The lamp body 4 below has base 2, and base 2 sets up on platform 1, rotates through lighting fixture 3 between base 2 and the lamp body 4 to be connected. The light emitting unit 41 is a lamp, the first light detecting unit 5 continuously receives light of the light emitting unit 41, when the detected brightness cannot reach the brightness of the light emitted by the light emitting unit 41, the low head shielding of a user is judged at the moment, and the controller 7 controls the light emitting unit 41 to perform relevant operation to remind the user of taking care of sitting postures, so that the light emitting unit is convenient to use and low in cost.
It should be noted that, the first light detecting unit 5 is a special sensor for measuring illumination intensity, and in this embodiment, a photoresistor is selected as a sensing device, and the photoresistor is a resistance device based on a photoresistor effect. The resistance value of the light intensity sensor changes along with the change of the light intensity, and can be used for measuring the light intensity.

As shown in fig. 2, for the intelligent myopia prevention desk lamp provided in this embodiment, further includes: the second light detection unit 6, the second light detection unit 6 is electrically connected with the controller 7, and the second light detection unit 6 can perform wavelength detection analysis on external light and send data to the controller 7; the light emitting unit 41 includes a light emitter capable of emitting multi-spectrum light and increasing or decreasing a single spectrum thereof. The second light detecting unit 6 transmits the detected light wavelength data to the controller 7, analyzes whether a certain wavelength exceeds or does not meet the light range suitable for learning by human eyes, and the controller 7 controls the light emitting unit 41 to decrease or increase the wavelength so that the range comfortable for human eyes can be reached. In addition, as an alternative embodiment, the second light detection unit 6 may be integrated into the first light detection unit 5.
It should be noted that the second light detection unit 6 is mainly used for detecting an environmental spectrum. There are many types of light sources included in the ambient light, and the spectra of different light sources are different, and the following list includes some common light sources in the ambient light and their spectra: sunlight is a white light that contains the entire visible spectrum, with wavelengths ranging from violet to red, but with the blue light at short wavelengths being the strongest. Incandescent lamps are warm white light sources that emit primarily yellow and red light, with spectra that are biased toward the red and yellow regions, and lack blue and violet light. The fluorescent lamp mainly emits green and blue light, and the proportion of blue light in the spectrum is high. LED lamps can emit light of various colors, the spectrum of which depends on their design and material choice. White LED lamps generally emit light from a mixture of blue LEDs and yellow phosphors, with some proportion of the blue light in the spectrum. Natural light refers to light rays in natural environment, and the spectrum of the natural light depends on factors such as solar altitude, cloud layers, atmospheric pollution and the like. In the case of sky blue, blue light occupies a relatively high proportion of the spectrum of natural light. Therefore, the spectrum difference of different light sources can influence the visual experience and the true restoration degree of the color, and the vision can be influenced tens of thousands of times, and attention should be paid to selecting a proper light source to avoid damaging eyes. The effect of different spectral combinations on vision can be considered in two ways: color temperature and color saturation. Color temperature: color temperature refers to the color properties of a light source, typically expressed in terms of values in kelvin (K). The higher the color temperature, the blue shade of the light, and the lower the color temperature, the yellow or red shade of the light. According to researches, high-color-temperature light (such as blue light and purple light) can negatively influence the vision, and long-time exposure to the light can cause problems of eye fatigue, vision degradation and the like. Color saturation: color saturation refers to the purity and vividness of a color, usually expressed in percent. The more saturated the color, the more irritating the human eye. In some scenes, high color saturation light (e.g., red, yellow, orange) may cause visual fatigue and discomfort, and prolonged exposure to such light may negatively impact vision. Therefore, from the viewpoint of protecting eyesight, it is recommended to use a light source having a suitable color temperature and a low color saturation, such as natural light, yellow warm light, white natural light, or the like. In order to achieve the above-mentioned functions, the light emitting unit 41 of this embodiment may be a multispectral light source, which may be formed by arranging and combining a plurality of single-spectrum light sources, or may be formed by a light source having a multispectral light source wick, and the design may be selected according to the situation. Meanwhile, in order to implement the functions, the lamp also has a controller 7, which can process the information of the collected light intensity and spectrum and control the multispectral light source.
In addition, more specifically, yellow light is suitable for vision protection, and the spectrum of optimum vision is yellow light with a wavelength in the range of 570-600 nm. This is because the yellow light can minimize astigmatism of human eyes while improving contrast and sharpness, so that the outline of an object is clearer. In activities such as reading, writing, drawing, computers and the like, the yellow light can be used for effectively reducing eye fatigue, reducing the appearance of eye fatigue symptoms and protecting eyesight. In addition, in different scenarios, a suitable spectrum may also be selected as desired. For example, warmer colored light may improve reading comfort while cooler colored light may improve attention and speed of response while performing fine activities. In summary, selecting a suitable spectrum can improve visual comfort and efficiency, which is critical to protecting vision and improving vision health.

The second light detecting unit 6 is provided with a filter 63 for filtering a single wavelength, in this embodiment, the filter 63 is a filter, and in this embodiment, the filter 63 is selected from 550 nm to 590 nm, preferably 560 nm, 570 nm or 580 nm. Under the illumination of 560 nm, 570 nm and 580 nm wavelength, the astigmatism of human eyes is minimum, the contrast and the definition can be improved, the asthenopia can be lightened, and the eye-protecting mask has a certain effect on the vision recovery of human eyes. The filter 63 is disposed above the receiving end of the second light detecting unit 6, and in other embodiments, the filter 63 may not be disposed. In addition, as an alternative embodiment, the second light detection unit 6 may further comprise a spectrum analysis module for counting the detected data and transmitting the data to the controller 7.
As shown in fig. 6, for the intelligent myopia prevention desk lamp provided in this embodiment, the spectrum detection member 62 includes a plurality of spectrum sensors 621, and the spectrum sensors 621 are arranged in the detection unit housing 65 in an array. The spectral sensors 621 are arranged in a circumferential array. The spectrum sensors 621 concentrically arranged in the mounting holes 8 are horizontally arranged, and the rest spectrum sensors 621 are obliquely arranged towards the mounting holes 8 for the receiving ends. The spectrum detecting member 62 is composed of a plurality of spectrum sensors 621 of different sensitive wavelengths and is divided into a plurality of angles to form an arc shape, and the intersection point of the center vertical line of the spectrum sensor 621 passing through the light dispersing member 61 is the center of the light dispersing member 61, so that the light path length of the light reaching the surface of each spectrum sensor 621 from the light dispersing member 61 is ensured to be uniform, thereby ensuring the accuracy and consistency of the detected information. The single incident ray can be made to enter the spectrum sensor 621 which reaches different positions and is in different sensitive wave bands through one lens. In addition, as an alternative embodiment, the spectral sensors 621 may be arranged in a linear array.
In addition, in some embodiments, to complete the above-described operation, the communication unit 64 may further include a first communication module and a second communication module. The first communication module is arranged in the second light detection unit 6 for processing the detected wavelength and analyzing; the second communication module is arranged in the base 2 and is used for receiving the signal of the first communication module and controlling the working state of the desk lamp.
Working principle of intelligent myopia prevention desk lamp: after the lamp is turned on, the light emitting unit 41 emits light, and the first light detecting unit 5 detects the brightness in the current environment and adjusts the brightness of the light emitting unit 41. The second light detecting unit 6 detects the spectrum in the current environment, and the controller 7 controls the light emitting unit 41 to increase or decrease the light of a certain wavelength by analyzing and transmitting the data to the controller 7. When the first light detecting unit 5 cannot receive the light of the light emitting unit 41, it is determined that the head of the user leans forward at this time, and the controller 7 controls the light emitting unit 41 to perform a flicker reminding to correct the sitting posture of the user.
