Problems solved by technology

[0009] (1) The color temperature adjustment of the adjustable color temperature lighting device 1' is determined by the adjustable color temperature range of the first light emitting diode 2' and the second light emitting diode 3', thus limiting the color temperature adjustable lighting device 1' color temperature adjustable range
In addition, the color temperature adjustable lighting device 1' also includes light emitting diodes with different color temperatures, which also causes manufacturing difficulties and increases costs.
[0010] (2) To adjust the brightness or illuminance of the color temperature adjustable lighting device 1', the driving voltage or current of the first light emitting diode 2' and the second light emitting diode 3' must be adjusted; however, in general, the light emitting element The brightness will increase with the increase of the color temperature, so that the color temperature adjustable lighting device 1' cannot adjust the brightness and color temperature separately

[0079] see Figure 4 , is a perspective view showing the first embodiment of an intelligent light source of the present invention. Also, please also refer to Figure 5 , is a structural diagram showing the first embodiment of the intelligent light source of the present invention. Such as Figure 4 As shown, 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 similar to sunlight (light resemblance with respect to sunlight), for example: the interior of a spaceship and the interior of a mine. It is worth noting that due to the increasingly dense urban buildings, many houses cannot have sufficient sunlight inside. Simultaneously, for those underground workers, for example: the employee of subway station, it cannot accept the irradiation of sufficient sunlight equally. Therefore, the intelligent light source 1 of the present invention can also be installe...

[0098] Please refer again Figure 4 and Figure 5 , and see also Figure 10 , showing the CIE chromaticity diagram obtained by measuring the color light emitted by the LED light source. In Experimental Example 1, LED light sources are used as the first light emitting element 111 and the second light emitting element 113, and the color temperature reducing film 112 is made to include quantum dots with a size between 5nm and 20nm. On the other hand, it must be noted that the LED light source used can emit colored light (pure white light) with a color temperature of 6000K. At the same time, it must be further explained that, Figure 10 The data obtained by using one piece of color temperature reducing film 112, two pieces of color temperature reducing film 112, three pieces of color temperature reducing film 112, and four pieces of color temperature reducing film 112 are used to reduce the color temperature of the color light emitted by the LED light source.

[0103] Please refer again Figure 4 and Figure 5 , and see also Figure 12 , to show the CIE chromaticity diagram obtained by measuring the color light emitted by an OLED light source. Figure 12 The data respectively use one color temperature reducing film 112, two color temperature reducing films 112, three color temperature reducing films 112, four color temperature reducing films 112, five color temperature reducing films 112, and six color temperature reducing films 112 , seven pieces of color temperature reducing films 112 , and eight pieces of color temperature reducing films 112 are obtained after performing color temperature reducing treatment on the color light emitted by an OLED light source (ie, the first light emitting element 111 ). Wherein, the used color temperature reducing film 112 includes quantum dots with a size ranging from 5 nm to 20 nm. Depend on Figure 12 It can be found that since the light-emitting surface of the second light-emitting element 1...

Abstract

The invention provides an intelligent light source. The intelligent light source includes a lighting module, a driver module and a controller module; wherein the lighting module includes a plurality of first light-emitting elements, at least one second light-emitting element and a plurality of color temperature down-regulation films. In particular, the light-emitting surface of each first light emitting element is connected with one or more color temperature down-regulation films which are stacked. By means of the design, color lights emitted by the different first light-emitting elements areconverted into the sunlight similar to the forenoon light, the sunlight similar to the morning and evening light, an orange-white light, or an orange-red light according to the stacking number of thecolor temperature down-regulation films. On the other hand, the second light-emitting element is used for emitting a color light with a high color temperature, for example, the sunlight is similar tothe noon light or the sunlight under a blue sky.
