In the optical system of the existing stage lamp, when the LED light source module passes through a coated lens coated with a dielectric film or a colored filter, the color temperature is not constant and is not uniform, and because the dielectric films coated with different materials or the colored filter coated with the coated lens can absorb or scatter incident light, the spectrum of the LED light source module can be changed after passing through coated glass or the colored filter, so that the color temperature of the LED light source module in the optical system of the existing stage lamp is not constant and is not uniform.
Based on this, referring to fig. 1, an optical system having an led light source module for maintaining a constant color temperature is provided according to an embodiment of the present utility model, including:
the LED light source module comprises a light emitting diode array, the light emitting diode array at least comprises two light emitting diode units with different light emitting colors, the LEDs of the light emitting diode units comprise a first LED light source and four second LED light sources, the four second LED light sources are arranged at equal intervals around the first LED light source, the first LED light source is used as a main light source of the light emitting diode unit, the second LED light source is used as a secondary light source of the light emitting diode unit, and the color temperature of the second LED light source is 50-9000K higher than that of the first LED light source.
According to the embodiment of the utility model, the optical system with the LED light source module for maintaining the constant color temperature has at least the following beneficial effects:
it can be understood that when the LED light source module in the existing optical system passes through the coated lens coated with the dielectric film or the optical filter coated with the color, the color temperature is not constant and uneven, because the coated lens coated with the dielectric film or the optical filter coated with the color of different materials absorbs or scatters the incident light, after passing through the coated glass or the optical filter coated with the color, the spectrum of the LED light source module is changed, so that the optical system with the LED light source module maintaining the constant color temperature according to the embodiment of the utility model has the advantages that the LED light source units in the LED light source array in the LED light source module comprise the first light source, namely the main light source, and the second light source, namely the secondary light source, and the color temperature of the second light source is higher than the color temperature 50-9000K of the first light source, so that when the color temperature of the main light source is reduced due to the external factor, the second light source can be used for compensating, the color temperature of the main light source is kept constant, and moreover, because the second light source is four, and the four second light sources are arranged around the first light source, namely the two adjacent second light sources, and the second light source can uniformly compensate the first light source. Therefore, according to the LED light source module with the constant color temperature, when the color temperature of the light emitted by the LED light source module is reduced through the optical components such as the film plating lens plated with the dielectric film or the optical component such as the optical filter plated with the color, the color temperature of the LED light source module is constant and uniform by arranging four secondary light sources, namely the secondary light sources, and arranging the secondary light sources around the primary light sources in a two-to-two adjacent manner.
It should be noted that, in the optical system according to the embodiment of the present utility model, the color temperature of the second light source is 50-9000K higher than the color temperature of the first light source, so it is understood that, because the color temperature of the first light source is reduced due to external reasons, the color temperature of the second light source needs to be higher than the color temperature of the first light source, but the reduced color temperature of the optical system due to external reasons is uncertain, such as the optical system needs a lens with a practical coating on one stage, and the optical system needs to use a combination of a coated lens and a color-coated filter on the other stage, so that the reduced color temperature is uncertain for different situations, and the color temperature of the second light source needs to be correspondingly adjusted to keep the color temperature of the first light source constant.
Further, it can be understood that at least two light emitting diodes with different light emitting colors are provided in the light emitting diode array, and because the optical system of the embodiment of the utility model is mainly used on a stage, and light mixing is often required on the stage, at least two light emitting diodes with different light emitting colors are provided in the light emitting diode array of the optical system of the embodiment of the utility model, and those skilled in the art can understand that the light emitting diode array of the optical system of the embodiment of the utility model can only have two light emitting colors, namely, light emitting diodes with red light and white light, and can also have four light emitting colors, namely, light emitting diodes with red light, white light, blue light and green light.
It is conceivable that, because the display effect of the circular light spots is good and more commonly used on the stage, the led units on the led array according to the embodiment of the present utility model are arranged in an approximately circular shape.
Further, it may be understood that, in order to ensure the light condensing effect of the optical system, a corresponding optical collimator array may be disposed in the light emitting direction of the LED light source module, for example, in one embodiment, a first optical collimator array is disposed in the light emitting direction of the LED light source module, the light incident surface of the collimator unit on the first optical collimator array is set to be concave, the light emitting surface is set to be spherical, the light incident surface of the collimator unit of the first optical collimator array is set to be concave, for better collecting the light emitted by the light emitting diode unit, the light emitting surface is set to be spherical, which is used for increasing the focal power of the collimator unit so as to enhance the light condensing effect of the first optical collimator array, and further, in order to further enhance the light receiving effect of the optical system, a second optical collimator array is disposed behind the first optical collimator array, and both the light incident surface and the light emitting surface of the collimator unit of the second optical collimator array are set to be aspheric, so as to further reduce the light beam angle of the light focused by the first step of the first optical collimator array.
Finally, it can be understood that the circuit board in the LED light source module of the optical system of the embodiment is regular hexagon, and the regular hexagon circuit board can enable the LED units to be in the limited substrate area, ensure heat dissipation, and meanwhile, the maximum number of LED units are arranged, and the regular hexagon circuit board is adopted to enable the light emitted by the LED light source module to be more close to an ideal uniform surface light source, so that light loss is reduced to the greatest extent.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
