Description

Intelligent light source

Technical Field

The present invention relates to the field of lighting devices, and more particularly, to an intelligent light source capable of automatically adjusting the brightness and color temperature according to the local real-time of a selected area.

Background

Since the invention of the lamp bulb by the kinson, with the advance of science and technology, the light source used by human has been developed from the lamp bulb to the Incandescent lamp (Incandescent bulb) and the Fluorescent lamp (Fluorescent tube); furthermore, the latest Lighting technology at present is Solid-State Lighting (SSL) technology, and for example, Light-Emitting diodes (LEDs), Organic Light-Emitting Semiconductors (OLEDs), and Polymer Light-Emitting diodes (PLEDs) are all products of the SSL technology.

Fig. 1 is a data graph showing color temperature versus luminous efficiency, and fig. 2 is a CIE chromaticity diagram. Specifically, a black body radiation curve is shown in the CIE chromaticity diagram of fig. 2, and the color temperature thereof changes approximately to sunlight (sunlight). Referring to fig. 1 and 2, the following table (1) further summarizes the color temperature of sunlight and the color temperature of the color light emitted from the lighting device.

Watch (1)

The united states general space service and George c. brainard long term research results at Philadelphia University (philiadelphia University) indicate that light does affect human hormone secretion. For example, cortisol is a "stress hormone" that can concentrate and counteract stress, and cortisol secretion is associated with the exposure to light. Melatonin, a sleep hormone produced only by the pineal gland in the dark, is widely known. Sunlight is a natural gift, and especially sunlight in the daytime can give people a feeling of vigorous atmosphere; in contrast, dusk exposure causes a person to have a depressed mood and a gradual relaxation. However, for those people who cannot have a working environment with sufficient sunlight, such as astronauts, miners and underground workers, the hormones in the body cannot be naturally secreted according to day and night changes, and the health of the people is seriously affected due to abnormal physiological circulation after a long time.

Accordingly, manufacturers of lighting devices have introduced a color temperature adjustable lighting device, so that users can adjust the brightness and color temperature of the light emitted by the lighting device. Fig. 3 is a schematic diagram showing a conventional illumination device with adjustable color temperature. As shown in fig. 3, the color temperature adjustable lighting device 1 ' mainly includes an array formed by a plurality of first light emitting diodes 2 ' and a plurality of second light emitting diodes 3 ' arranged in a crossed manner, wherein the first light emitting diodes 2 ' can emit a warm white light 4 ' with a color temperature range of 2500K to 4000K, and the second light emitting diodes 3 ' can emit a cold white light 5 ' with a color temperature range of 6000K to 10000K. Moreover, as shown in fig. 1, the warm white light 4 'and the cool white light 5' are combined to form an output light 6 ', and the color temperature of the output light 6' depends on the relative contribution ratio of the warm white light 4 'and the cool white light 5'.

Although the color temperature tunable lighting device 1 ' shown in fig. 3 does provide the function of user's own determination or adjustment of color temperature, the electronic engineers who have been involved in the design and development of the lighting device for a long time now know through the feedback of the end user that the color temperature tunable lighting device 1 ' shows the following disadvantages in practical applications:

(1) the color temperature modulation of the color temperature adjustable lighting device 1 'is determined by the adjustable color temperature ranges of the first light emitting diode 2' and the second light emitting diode 3 ', thereby limiting the color temperature adjustable variation range of the color temperature adjustable lighting device 1'. In addition, the color temperature adjustable lighting device 1' includes light emitting diodes with different color temperatures, which causes difficulty in manufacturing and increases cost.

(2) To adjust the brightness or illumination of the color temperature adjustable illumination apparatus 1 ', the driving voltages or currents of the first light emitting diode 2 ' and the second light emitting diode 3 ' must be adjusted; however, in general, the brightness of the light emitting elements increases with the increase of the color temperature, so that the color temperature tunable illumination apparatus 1' cannot separately modulate the brightness and the color temperature.

As can be seen from the above description, how to design a light source capable of separately modulating color temperature and brightness (illumination) becomes a very important issue. Accordingly, the present invention provides an intelligent light source, which is a light source of the present invention.

Disclosure of Invention

For people who are in a working environment where they cannot have sufficient sunlight, sunlight that can enjoy different color temperatures according to local real-time contributes to their body hormones being naturally secreted based on day-night changes. Although the prior art provides a color temperature adjustable lighting device, the color temperature of the output light of the color temperature adjustable lighting device cannot be widely adjusted. It is therefore a primary object of the present invention to provide an intelligent light source, comprising: a lighting module, a driver module and a controller module, wherein the lighting module comprises: the film comprises a plurality of first light-emitting elements, at least one second light-emitting element and a plurality of color temperature modulation films. In particular, one or more color temperature-adjusting films stacked on top of each other are connected to the light-emitting surface of each first light-emitting element. By such design, the color lights emitted by the different first light emitting elements are converted into pseudo-solar light in the morning, pseudo-solar light in the early morning and evening, orange-white light or orange-red light according to the stacking number of the color temperature adjusting films. On the other hand, the second light emitting device is used for emitting colored light with high color temperature, such as sunlight simulating noon or sunlight under blue sky. It is worth emphasizing that the controller module controls the driver module to correspondingly drive at least one of the plurality of first light emitting elements and/or the at least one second light emitting element to emit light according to the local real-time of a specific region selected by the user, so that the intelligent light source can correspondingly provide illumination with a light source similar to sunlight based on the local real-time of the selected region.

To achieve the above objective of the present invention, the present inventors provide an embodiment of the intelligent light source, which includes:

a lighting module, comprising:

a plurality of first light emitting elements for emitting a first color light;

at least one second light emitting element for emitting a second color light; and

one or more mutually stacked color temperature adjusting falling films connected to a light emitting surface of the first light emitting element for performing a color temperature adjusting falling process on a first color light emitted by the light emitting element; wherein, the color temperature of the first color light is reduced along with the increase of the number of the color temperature modulation films, and a CIE chromaticity coordinate of the first color light and the second color light is adjacent to a Black body radiation curve (Black body radiation curve) on a CIE chromaticity diagram;

the driver module is electrically connected to the lighting module and used for driving one or more first light-emitting elements and/or second light-emitting elements to emit light; and

a controller module for controlling the driver module, comprising:

a region selection unit for selecting a specific region;

a clock unit for correspondingly providing a local real-time based on the specific region;

a microprocessor electrically connected to the region selection unit, the clock unit and the database;

the microprocessor sends a control signal to the driver module according to the specific region and the local real-time, so that the driver module drives at least one of the first light-emitting elements and/or the at least one second light-emitting element to emit light.

Detailed Description

In order to more clearly describe the intelligent light source of the present invention, the following description will be made in detail with reference to the accompanying drawings.

First embodiment

Fig. 4 is a perspective view showing a first embodiment of an intelligent light source according to the present invention. Fig. 5 is a schematic diagram showing a first embodiment of an intelligent light source according to the present invention. As shown in fig. 4, the intelligent light source 1 of the present invention is used to provide illumination to a working environment that cannot have sufficient sunlight irradiation with a light simulation (light emission with reflected to sun) light source, such as: the interior of the spacecraft and the interior of the pit. It is worth mentioning that many houses do not have sufficient sunlight inside because of the increasing density of urban buildings. Meanwhile, for underground workers, such as staff of subway stations, the underground workers cannot receive sufficient sunlight. Thus, the intelligent light source 1 of the present invention can also be installed in similar areas that are not exposed to sufficient sunlight.

With continued reference to fig. 4 and 5. The intelligent light source 1 of the present invention mainly comprises: alighting module 11, adriver module 12 and acontroller module 13. Specifically, thelighting module 11 includes a plurality of firstlight emitting elements 111, at least one secondlight emitting element 113, and a plurality of colortemperature modulation films 112. It should be noted that the firstlight emitting element 111 and the secondlight emitting element 113 may be substantially the same light emitting element, for example: fluorescent lamps, light emitting diodes, quantum dot light emitting diodes, organic light emitting diodes, combinations of any two or more of the foregoing. Preferably, the light emitting elements with high color temperature (>6000K) are selected as the firstlight emitting element 111 and the secondlight emitting element 113, so that the light emitted by the intelligent light source 1 can more closely resemble sunlight.

According to the design of the present invention, one or more colortemperature adjusting films 112 stacked on top of each other are connected to the light emitting surface of each firstlight emitting element 111. The inventors of the present invention have found that the single color temperaturemodulation falling film 112 can perform a color temperature modulation falling process on a first color light emitted by the firstlight emitting element 111. Interestingly, while the color temperature of the first color light is being reduced, the color temperature-adjustingfilm 112 also reduces the brightness of the first color light. In addition, the inventors further found that, compared to a single color temperaturemodulation falling film 112, more than two color temperaturemodulation falling films 112 have a significant effect of enhancing the color temperature and brightness modulation of the first color light. The experimental data on the color temperature and brightness adjustment and reduction effects of the stacked number of the colortemperature adjustment films 112 on the color temperature and brightness of the first color light emitted by the firstlight emitting element 111 are summarized in the following table (2).

Watch (2)

Continuing to refer to fig. 6, a perspective view of the light emitting device and the color temperature adjusting film is shown. Fig. 7 is a side sectional view of the color temperature tuning film. As shown in fig. 6, one or more colortemperature adjusting films 112 may be disposed on the light emitting surface of the firstlight emitting element 111. In the present invention, the colortemperature tuning film 112 is a light conversion film. As can be seen from table (2), the color temperature of the color light emitted from the first light-emittingelement 111 decreases with the number of stacked color temperature-adjustingfilms 112. It is noted that, as the number of the colortemperature adjusting films 112 increases, the color light emitted by the firstlight emitting element 111 is gradually converted into an Orange-white light (Orange-white); finally, the color light emitted by the firstlight emitting device 111 is converted into Orange light (Orange red), and the color temperature range of the Orange light is between 1500K and 2000K.

The color temperaturemodulation falling film 112 mainly includes a polymer matrix PM and a plurality of light conversion particles LP doped or coated in the polymer matrix PM; wherein the polymer matrix PM may be any one of the following: polydimethylsiloxane (PDMS), polymethyl methacrylate (poly (methyl methacrylate), PMMA), Polystyrene (PS), Polyethylene terephthalate (PET), Polycarbonate (PC), Cyclic Olefin Copolymer (COC), Cyclic Block Copolymer (CBC), Polylactic acid (PLA), Polyimide (PI), a combination of any two of the foregoing, or a combination of any two or more of the foregoing. On the other hand, the light conversion particles LP may be quantum dots or phosphor particles; wherein the quantum dot may be any one of: a quantum dot of a group II-VI composite, a quantum dot of a group III-V composite, a quantum dot of a group II-VI composite having a shell-core structure, a quantum dot of a group III-V composite having a shell-core structure, a quantum dot of a non-spherical group II-VI composite having an alloy structure, a combination of any two of the foregoing, or a combination of any two or more of the foregoing. The following table (3) exemplarily lists several commonly used quantum dot materials. Meanwhile, the relationship between the size of the quantum dot and the color of the light of the photoluminescence can be referred to the related arrangement of the following table (4).

In another aspect, the phosphor can be any one of: silicate phosphor, aluminate phosphor, phosphate phosphor, sulfide phosphor, nitride phosphor, oxynitride phosphor, a combination of any two of the above, or a combination of any two or more of the above. The following table (5) exemplarily lists several commonly used phosphor materials.

Watch (5)

The above tables (3) and (5) list only exemplary materials of the light conversion particles LP, but it should be noted that the technical features of the present invention are not limited to the application of the specific materials of the light conversion particles LP. For example, the light conversion particles LP may also be a combination of phosphor particles and quantum dots. It should be noted that if quantum dots are used as the main material of the light conversion particles LP, a moisture barrier layer may be further coated on the surface of the polymer matrix PM to prevent moisture or oxygen from infiltrating into the polymer matrix PM to damage the light conversion particles LP when thecolor tuning film 112 is realized or manufactured. The moisture barrier layer can be made of any one of the following materials: polyethylene terephthalate (PET), Polyethylene naphthalate (PEN), polymethyl methacrylate (PMMA), silicon oxide, titanium oxide, aluminum oxide, a combination of any two of the above, or a combination of any two or more of the above.

It should be noted that, in order to facilitate the application of the color temperature adjusting fallingfilm 112 to other firstlight emitting elements 111 or other light sources capable of serving as the firstlight emitting elements 111, in practice, the color temperature adjusting fallingfilm 112 may also be formed by a transparent substrate and multiple layers of light conversion coatings. Fig. 8 is a side sectional view showing the first light emitting device and the color temperature-adjusting falling film. As shown in fig. 8, an organic light emitting diode may be practically used as the firstlight emitting element 111, which structurally includes: atransparent substrate 1A, ananode 1B formed on a surface of thetransparent substrate 1A, ahole injection layer 1C formed on theanode 1B, ahole transport layer 1D formed on thehole injection layer 1C, alight emitting layer 1E formed on thehole transport layer 1D, anelectron transport layer 1F formed on thelight emitting layer 1E, anelectron injection layer 1G formed on theelectron transport layer 1F, and acathode 1H formed on theelectron injection layer 1G. Also, one or more color temperature-adjustingfilms 112 are connected to the light-emitting surface of the first light-emitting element 111 (i.e., the bottom surface of thetransparent substrate 1A).

Fig. 9 is a side sectional view of the first light emitting device and the color temperature adjusting film. As shown in fig. 9, in practice, a light emitting diode may also be used as the firstlight emitting element 111, which structurally includes: an insulating body 10 ', a lead frame including a first electrical component 13 ' and a second electrical component 14 ', an LED die 12 ', and an encapsulant 11 '. As shown in fig. 9, the insulating body 10 'has an LED mounting groove for receiving the LED die 12'. Moreover, the first electrical component 13 'and the second electrical component 14' both have a soldering portion and an electrical connection portion; wherein the soldering portion is exposed inside the LED mounting groove, and the electrical connection portion penetrates outside the insulating main body 10'. It should be noted that the encapsulant 11' is doped with phosphor. And, the short wavelength light emitted from the LED die 12 'is converted into white light after passing through the encapsulant 11'. Further, the one or more colortemperature tuning films 112 reduce the color temperature and brightness of the white light.

Experimental example 1

Referring to fig. 4 and 5 repeatedly, and referring to fig. 10, a CIE chromaticity diagram obtained by measuring color light emitted from the LED light source is shown. In the first experimental example, an LED light source is used as the firstlight emitting element 111 and the secondlight emitting element 113, and the color temperature adjusting fallingfilm 112 includes quantum dots with a size between 5nm and 20 nm. On the other hand, it should be noted that the LED light source used can emit light with a color temperature of 6000K (pure white light). Meanwhile, it should be further explained that the data of fig. 10 is obtained after color temperature-down-converting the color light emitted from the LED light source using one color temperature-convertingfilm 112, two color temperature-convertingfilms 112, three color temperature-convertingfilms 112, and four color temperature-convertingfilms 112.

As can be seen from fig. 10, the second color light emitted by the secondlight emitting element 113 is Pure white light (Pure-white light) with a color temperature of about 6000K, and its CIE chromaticity coordinates are close to the black body radiation curve. On the other hand, for the firstlight emitting element 111 whose light emitting surface is provided with a colortemperature modulation film 112, the first color light emitted therefrom is Warm white light (Warm-white light) having a color temperature of about 4150K, and its CIE chromaticity coordinates are also close to the black body radiation curve. Furthermore, for the firstlight emitting element 111 having two colortemperature adjusting films 112 on the light emitting surface, the first color light emitted therefrom is warm white light with a color temperature of about 3000K, and the CIE chromaticity coordinates thereof are also close to the black body radiation curve. On the other hand, for two firstlight emitting elements 111 having three colortemperature modulation films 112 and four colortemperature modulation films 112 on the light emitting surface, the emitted first color lights are orange lights with color temperatures of about 2000K and 1500K, respectively, and the CIE chromaticity coordinates thereof are also close to the blackbody radiation curve.

Please continue to refer to the CIE chromaticity diagram of fig. 11, which is obtained by measuring the color light emitted from an LED light source. The data of fig. 11 is obtained by subjecting color light emitted from the LED light source (i.e., the first light emitting element 111) to color temperature reduction processing using one color temperatureadjustment falling film 112, two color temperatureadjustment falling films 112, three color temperatureadjustment falling films 112, four color temperatureadjustment falling films 112, five color temperatureadjustment falling films 112, six color temperatureadjustment falling films 112, seven color temperatureadjustment falling films 112, and eight color temperatureadjustment falling films 112, respectively. The color temperature-adjusting fallingfilm 112 used therein comprises quantum dots with a size ranging from 3nm to 10 nm. As can be seen from fig. 11, the second color light emitted by the secondlight emitting element 113 is Pure white light (Pure-white light) with a color temperature of about 6000K, and its CIE chromaticity coordinates are close to the black body radiation curve. Also, as the number of stacked colortemperature tuning films 112 increases, the color temperature of the second color light emitted by the secondlight emitting element 113 correspondingly decreases, and the CIE chromaticity coordinates of the second color light are adjacent to the black body radiation curve on the CIE chromaticity diagram.

From the experimental data of fig. 10 and 11 and the significance represented by the color temperature of the sunlight loaded in table (1), it can be known that the second color light of the pseudo-midday sunlight can be further converted into pseudo-midday sunlight, pseudo-early morning and evening sunlight, orange white light, or orange red light by adjusting the number of stacked colortemperature adjusting films 112. Meanwhile, we can also know that if the LED light source with the color temperature greater than 6500K is used as the firstlight emitting element 111 and the secondlight emitting element 113, the intelligent light source 1 of the present invention can also provide illumination simulating sunlight in a blue sky.

Experimental example two

Please refer to fig. 4 and 5 repeatedly, and also refer to fig. 12, which shows a CIE chromaticity diagram obtained by measuring the color light emitted from an OLED light source. The data of fig. 12 is obtained by subjecting color light emitted from one OLED light source (i.e., the first light emitting element 111) to color temperature reduction processing using one color temperatureadjustment falling film 112, two color temperatureadjustment falling films 112, three color temperatureadjustment falling films 112, four color temperatureadjustment falling films 112, five color temperatureadjustment falling films 112, six color temperatureadjustment falling films 112, seven color temperatureadjustment falling films 112, and eight color temperatureadjustment falling films 112, respectively. The color temperature-adjusting fallingfilm 112 used therein contains quantum dots with a size of 5nm to 20 nm. As can be seen from fig. 12, since the light emitting surface of the secondlight emitting element 113 is not provided with any colortemperature adjusting film 112, the second color light emitted therefrom is a color light having a color temperature of about 5400K (warm white light), and the CIE chromaticity coordinates of the second color light are close to the black body radiation curve. Also, as the number of stacked colortemperature tuning films 112 increases, the color temperature of the second color light emitted by the secondlight emitting element 113 correspondingly decreases, and the CIE chromaticity coordinates of the second color light are adjacent to the black body radiation curve on the CIE chromaticity diagram.

Obviously, although the OLED light source used in the second experimental example can only emit nearly pure white light, the pure white light (i.e., the first color light emitted by the first light emitting element 111) can be further converted into pseudo-morning sunlight, pseudo-morning and evening sunlight, orange-white light, or orange-red light by adjusting the number of stacked colortemperature adjusting films 112. Meanwhile, it can be known that if the OLED light source with a color temperature greater than 6000K is used as the firstlight emitting element 111 and the secondlight emitting element 113, the intelligent light source 1 of the present invention can correspondingly provide illumination to a working environment (such as a spacecraft or a mine pit) that cannot have sufficient sunlight irradiation with a light source (light emission with reflection to sun) similar to sunlight according to the local real-time of a specific region.

With continuing reference to fig. 4 and 5 and with concurrent reference to fig. 13, a block diagram of the internal circuitry of the controller module is shown. According to the design of the present invention, thedriver module 12 is electrically connected to thelighting module 11 for driving one or more of the firstlight emitting elements 111 and/or the secondlight emitting elements 113 to emit light. On the other hand, as can be seen from fig. 4, 5 and 13, the user can control thedriver module 12 through thecontroller module 13. Further, thecontroller module 13 mainly includes: aregion selection unit 131, aclock unit 132, adatabase 133, and amicroprocessor 134. Theregion selection unit 131 is used for the user to select a specific region, such as: taiwan or usa. After the selection of the specific region is completed, theclock unit 132 may provide a local real-time based on the selected region. On the other hand, thedatabase 133 stores therein solar light data corresponding to the specific region and the current real time of the specific region, and includes: brightness and color temperature.

As described above, themicroprocessor 134 is electrically connected to theregion selection unit 131, theclock unit 132, and thedatabase 133. According to the design of the present invention, themicroprocessor 134 controls thedriver module 12 to drive at least one of the plurality of firstlight emitting elements 111 and/or the at least one secondlight emitting element 113 to emit light according to the specific region and the real time, so that the intelligent light source 1 correspondingly provides illumination with a light source similar to sunlight to a working environment (such as a space ship or a mine pit) which cannot have sufficient sunlight irradiation according to the local real time of the region selected by the user. Furthermore, thecontroller module 13 further includes acommunication unit 135 and a human-machine interface unit 136, wherein thecommunication unit 135 is electrically connected to themicroprocessor 134 for enabling thecontroller module 13 to communicate with an externalelectronic device 2. The human-machine interface unit 136 is electrically connected to themicroprocessor 134 for a user to operate thecontroller module 13. It should be noted that although fig. 4 and fig. 5 show that theelectronic device 2 is a smart phone, in practice, theelectronic device 2 may be otherelectronic devices 2, such as: a desktop computer, a laptop computer, a tablet computer, or an intelligent watch.

Second embodiment

Referring to fig. 14, a second embodiment of an intelligent light source according to the present invention is shown. As can be seen by comparing fig. 5 and fig. 14, the second embodiment of the intelligent light source 1 further comprises anoptical receiver module 14. When the intelligent light source 1 of the present invention is applied to a pit, an underground railway, and a house which cannot have sufficient sunlight irradiation, thelight receiver module 14 can be disposed on the ground and electrically connected to thecontroller module 13. So designed, theoptical receiver module 14 receives an ambient light (i.e., sunlight) on the ground and transmits an ambient light data to thecontroller module 13. Further, themicroprocessor 134 sends a control signal to thedriver module 12 to enable thedriver module 12 to drive at least one of the firstlight emitting elements 111 and/or the at least one secondlight emitting element 113 to emit light, so that the intelligent light source 1 can correspondingly provide illumination with a light source similar to sunlight based on the ambient light data.

Thus, all embodiments and structural components of the intelligent light source of the present invention have been fully and clearly described above; moreover, the present invention has the following advantages as follows:

(1) for people in a working environment where they cannot have sufficient sunlight, sunlight that can enjoy different color temperatures based on local real-time contributes to their natural secretion of hormones in the body based on day-night changes. Although the prior art provides a color temperature adjustable lighting device, the color temperature of the output light of the color temperature adjustable lighting device cannot be widely adjusted. In contrast, the present invention uses alighting module 11, adriver module 12 and acontroller module 13 to form an intelligent light source 1. In particular, thelighting module 11 comprises: the display device comprises a plurality of first light-emittingelements 111, at least one second light-emittingelement 113 and a plurality of color temperaturemodulation falling films 112, wherein one or more color temperaturemodulation falling films 112 stacked with each other are connected to a light-emitting surface of each first light-emittingelement 111. With such a design, the color lights emitted by the different firstlight emitting elements 111 are converted into pseudo-solar light in the morning, pseudo-solar light in the early morning and evening, orange-white light, or orange-red light according to the number of stacked colortemperature adjusting films 112. On the other hand, the secondlight emitting element 113 is used to emit a color light with a high color temperature, such as sunlight simulating noon or blue sky.

(2) Further, after the user selects a specific region through thecontroller module 13, thecontroller module 13 controls thedriver module 12 to drive at least one of the first light-emittingelements 111 and/or the at least one second light-emittingelement 113 to emit light according to the selected local real-time, so that the intelligent light source 1 correspondingly provides illumination with a light source similar to sunlight according to the local real-time of the region selected by the user. Thus, the intelligent light source 1 of the present invention is particularly suitable for being applied to provide illumination to a working environment which cannot have sufficient sunlight irradiation with a light source simulating sunlight, such as: the interior of the spacecraft and the interior of the pit.
