MULTl-COLOR SEMICONDUCTOR LAMP BACKGROUND OF THE INVENTION I. Field of the Invention This invention relates to semiconductor lamps and more particularly, to multi-color semiconductor lamps capable of emitting light of many different colors from what appears to be a single light source.
2. Description of the Prior Art A typical example of a multi-color indicating device is a traffic signal lamp device. It consists of three different light sources arranged side by side respectively emitting the lights of red, orange and green colors, these light sources being selectively and individually switched, on and off electrically, and the colors ofthese sources respectively indicating the condition of danger, caution and safety. Since the multi color indicating device of this type has the excellent function of permitting an observer to recognize various conditions instinctively, there are extensive applications for these devices such as for indicating the working state of apparatus, for indicating the occupancy of roads and seats, for indicating positive or negative signs of various values, for indicating whether some value is greater or less than a reference value and for indicating whether an input signal is correct or not.
However, prior-art multi-color indicating devices such as the afore-mentioned traffic signal lamp device usually use a separate light sources for each different color, and the individual light sources are located at different positions. Therefore, an undesirably large space is required for the whole device. Also, unless the device is located in a dark place, the light sources which are not emitting light are likely to be mistaken for those emitting light since they can reflect ambient light.
Due to the above drawbacks it has heretofore been very difficult to achieve clear multi-color indication with a small light emitting device or lamp.
In order to overcome the afore-mentioned drawbacks it has been proposed to dispose a plurality of filters individually transmitting the lights of respectively different particular wavelengths in front of a single white light source and switch or position these filters by a suitable means or provide light sources disposed at the focuses of lenses or curved mirrors mounted in a panel such that these light sources may be not seen from the back of the panel and suitably switch these light sources on and off by an appropriate means. All of such systems, however require very complicated mechanism, so they are not in popular use yet.
An ideal multi-color indicating device or lamp would be one from which light of two or more colors can be I emitted from an apparently single light source with the color selected by simple electric control. Such a light source, which would thereby occupy an optimally minimum amount of space, has not been practically available prior to the present invention.
An object of the present invention is to provide a novel and improved multi-color semiconductor lamp.
Another object of the invention is to provide a multicolor semiconductor lamp, which can emit light of dif ferent colors apparently from a single light source.
A further object of the invention is to provide a multi-color semiconductor lamp, which is capable of emitting light of different colors, but occupies smaller space and nevertheless permits to emit light in clear and distinct colors.
SUMMARY OF THE INVENTION According to the invention, a plurality of lightemitting diodes individually capable of emitting the light of respectively different colors are disposed close to one another, and these light-emitting diodes are covered with a light scattering layer such that light from any one of this plurality of light sources corresponding to a respective color is seen as if emitted apparently from the same source or position, whereby multicolor indication with the respectively different colors of the individual light emitting diodes as well as blends of these colors may be obtained.

The two diodes A and B are disposed closely adjacent one another on an internal surface of a common metal casing 1 such that ohmic contact is made between one side of each of the diodes A and B and the said casing 1. Both diodes are encased in a commonlight scattering layer 2 on the casing I.
The diodes A and B are respectively connected to external terminal leads 3 and 5 which extend through the casing 1 within respectiveinsulating sleeves 11 and 12. The internal ends of the terminal leads 3 and 5 are respectively connected throughmetal wires terminal lead 4 for both diodes is conductively connected to the underside of the metal casing l.
A lens C is positioned over thelight scattering layer 2 to confine the said layer and the diodes A and B within the said casing 1.
The light emitting diode A is energized to emit light of its chosen color by impressing an appropriate voltage between the input terminal leads 3 and 4 and the light emitting diode B is energized to emit light of its chosen color by impressing an appropriate voltage between the input terminal leads 4 and 5. When these diodes are so energized, either one at a time or concurrently, the resulting light emitted thereby is scattered in passing through thelight scattering layer 2 so that all such emissions transmitted to the exterior of the casing 1 through the lens C appear to come from one and the same source.
FIG. 2 shows a modified construction in which like elements to FIG. I bear like numerals. In this case, the casing I has an inner reflecting surfaces, and thelight scattering layer 2 is covered with atransparent resin layer 6 having a lens-shaped outer surface L.
FIG. 3 shows another embodiment in which like elements to FIGS. I and 2 bear like numerals. In this case, light emitting diodes A and B' for converting infrared rays to visible light respectively consisting of infraredluminescent diodes light scattering layer 2 andtransparent resin layer 6 as previously described with reference to FIG. 2.
While the constructions shown in FIGS. I to 3 have used two light-emitting diodes for emitting respectively different visible lights, similar effects may of course be obtained if three or more different light-emitting diodes are used.
Also, colored light resulting from the blending of the individual colors from the respective light emitting diodes may be obtained by causing two or more of the said lightemitting diodes to simultaneously emit light.
The light-emitting diodes may be visible lightemitting diodes, or a combination of an infrared luminescent diode with a fluorescent material for emitting visual light in response to the infrared emissions.
Thelight scattering layer 2 of the several embodiments of the invention may comprise a ground glass body disposed in the position of the lens C of FIG. 1 or located between the light-emitting diodes A and B and the lens C.
Alternatively, thelight scattering layer 2 may comprise fine alumina powder bonded with resin.
For infrared to visual conversion, thelight scattering layer 2 may comprise powdered phosphors (the fluo rescent material responsive to infrared emissions) bonded with resin.
As has been described, according to the invention a variety of combinations may be incorporated into the device; for instance it is possible to provide a device where a plurality of visible light-emitting diodes capable of emitting respectively different colored light are covered with a light-scattering layer, a device where a plurality of infrared luminescent diodes in combination with respective fluorescent powders capable of converting infrared rays into visible light of different colors are wholly covered with a light scattering layer, or a device where a visible light emitting diode and an infrared luminescent diode are covered with a fluorescent material for visualizing the infrared and scattering the visible light.
Also, by using not only the ordinary light emitting diodes having only one p-n junction but also one or more multi-color emitting diodes each having two or more p-n junctions defined between successively laminated layers of semiconductor crystal presenting different band gaps, three or more colors of luminescence may be very readily obtained.
EXAMPLE I In the multi-color semiconductor lamp of FIGS. I and 2, a green light-emitting gallium phosphide diode is used as light-emitting diode A, a red light-emitting gallium phosphide diode is used as light-emitting diode 10 B. and an epoxy resin body containing fine powder of alumina is used aslight scattering layer 2. Green light is emitted from the light-emitting diode A by impressing between the input terminal leads 3 and 4 an electric input of 3.5 volts and i0 milliamperes, and red light is emitted from the light emitting diode B by impressing between the input terminal leads 4 and 5 the same electric input. These emitted lights are projected through the lens C or thetransparent resin layer 6 as the case may be.
EXAMPLE 2 In the light-emitting semiconductor lamp of FIG. 3, the light-emitting diode A' comprises a light emitting diode in which an infrared luminescentgallium arsenide diode 7 is covered with a layer 9 consisting of sodium yttrium fluoride fluorescent powder activated with ytterbium and erbium and a resin bonded therewith; and the lightemitting diode B comprises a light emitting diode in which an infrared luminescentgallium arsenide diode 8 is covered with a layer 10 consisting of yttrium oxyfluoride phosphor powder activated with ytterbium and erbium and a resin bonded therewith. Over these fluorescent powder layers 9 and I0, thelight scattering layer 2 is provided comprising a fine alumina powder bonded with resin and the fluorescent powder layers 9 and 10 together with thealumina powder layer 2 are covered with theepoxy resin layer 6.
Green light is emitted through theepoxy resin layer 6 by impressing an electric input of 1.2 volts and 50 milli' amperes between the input terminal leads 3 and 4 for the light-emitting diode A, and red light is emitted through the same layer by impressing an electric input of 1.2 volts and 100 millivolts between the input terminal leads 4 and 5 for the light emitting diode B.
EXAMPLE 3 A light emitting semiconductor lamp having a function similar to that of Example 2 is obtained by utilizing, in the fluorescent layer 10, yttrium oxychloride fluorescent powder activated with ytterbium and erbium in place of yttrium oxyfl uoride activated with ytterbium and erbium of Example 2.
EXAMPLE 4 milliamperes This example is one modification of the lamp of FIG. 2 or FIG. 3, and is shown in FIG. 5, wherein the light emitting diode A is replaced by a red light-emitting gallium arsenide diode and the light-emitting diode B is replaced by a light emitting diode in which an infrared luminescent gallium arsenide diode is combined with the fluorescent layer 10 consisting of sodium yttrium fluoride fluorescent powder activated with ytterbium and erbium. These light-emitting elements A and B are covered with alight scattering layer 2 of sodiumyttrium fluoride fluorescent powder activated with ytterbium and erbium, which is fixed with apolystyrene layer 6 covering it. Red light is emitted through thepolystyrene layer 6 by impressing an electric input of 1.7 volts and 20 milliamperes between the input terminal leads 3 and 4 for the light-emitting element A, and green light is emitted through the same layer by impressing an electric input of 1.2 volts and 60 milliamperes between the input terminal leads 4 and 5 for the light-emitting element B. In this case, thelight scattering layer 2 and a fluorescent layer which contain the fluorescent powders serve the dual roles of both converting the wavelengths of light and scattering light.
This lamp is a modification of that of Example 2 in that a red light emitting diode A and an infraredemitting diode 8 are covered directly with alight scattering layer 2 containing powdered fluorescent material.
EXAMPLE 5 A light emitting semiconductor lamp having a function similar to that of Example 4 is obtained by using, in the fluorescent layer 10, yttrium fluoride fluorscent powder activated with ytterbium and erbium in place of sodium yttrium fluoride fluorescent powder activated with ytterbium and erbium.
EXAMPLE 6 A yellow light-emitting gallium phosphide diode is used as a third light-emitting diode (not shown) in addition to the two light-emitting diode A and B' of Example 4. Red light is emitted by impressing an electric input of 1.7 volts and 20 milliamperes between the input terminal leads 3 and 4 for the light-emitting diode A, while green light is emitted by impressing an electric input of 1.2 volts and 60 milliamperes between the input terminal terminal leads 4 and 5 for the lightemitting diode B, and yellow light is emitted by impressing an electric input of 3.5 volts and 10 milliamperess between theinput terminal lead 4 and a similar additional input lead (not shown) extending through the casing 1 like theleads
EXAMPLE 7 1n the lamp of Example 2, green light is emitted by impressing an electric input of 1.2 volts and 50 milliamperes between the input leads 3 and 4 for the lightemitting diode A', while red light is emitted by impressing an electric input of 1.2 volts and 100 milliamperes between the input leads 4 and 5 for the light emitting diode B, and yellow light is emitted by simultaneously impressing an electric input of 1.2 volts and 40 milliamperes between the input leads 3 and 4 for the lightemitting diode A' and an electric input of 1.2 volts and 80 milliamperes between the input leads 4 and 5 for the light emitting diode B. it will thus be seen that light of three different colors can be emitted in employing only two different light-emitting diodes.
EXAMPLE 8 This example is realized by using the construction as shown in FIG. 2, but a light-emitting diode having two p-n junctions is used as one of the two light-emitting elements for three-color emission, as will be described with reference to FIG. 4.
Referring to the diagrams, light emitting-diode A" is constituted by a conventional light emitting gallium phosphide diode, and light emitting diode B" is composed of a GaAs crystal doped with Si and a GaAs P crystal, each said crystal containing a p-n junction.
6Lightscattering layer 2 is formed by hardening a coating of epoxy resin containing yttrium fluoride fluorescent powder activated with ytterbium and erbium.
Thecrystal 13 makes ohmic contact with the casing 1 and its p-n junction makes ohmic contact with the crystal 14. The p-n junction of the crystal 14 is connected with themetal wire 5A from theinput terminal lead 5 and the crystal 14 is connected with ametal wire 5A extending from an input terminal lead 5' extending through the casing 1 via an insulating sleeve 12' in the same manner as the input terminal leads 3 and 5 extend through the sleeves I1 and 12, respectively.
With this lamp, green light having a wavelength of 5,600 A is emitted through theresin layer 6 by impressing voltage between input terminal leads 3 and 4, while blue light having a wavelength of 4,750 A is emitted through thesame layer 6 by impressing voltage be tween input terminal leads 5 and 5', and red light having a wavelength of 6,600 A is emitted through thesame layer 6 by impressing voltage between input terminal leads 4 and 5'.
While this embodiment has used a double p-n junction diode composed of GaAs P crystal and GaAs crystal doped with Si, it is also possible to use various other double p-n junction diodes, for instance those composed of Gal crystal doped with Zn and O, and GaP crystal doped with Zn and N.
Also, by using not only the double junction diode but also a multiple junction diode formed by laminating a greater number of diodes, it is possible to obtain a far greater number of colors for the indication of the occurrence ofa correspondingly greater number of conditions being monitored.
