Abstract
The invention relates to an illumination lamp. The illumination lamp comprises a casing, light-emitting diode (LED) light sources of at least two different light colors. The LED light sources are installed in the casing, a diffusion panel is arranged at a light outlet of the casing, and at least one kind of the LED light sources is emitted to the diffusion panel directly, diffused and distributed through lenses and emitted to the diffusion panel. Compared with the prior art, the lenses which diffuse and distribute the at least one kind of the LED light sources are arranged, even the LED light source of the light color is few, light rays of the LED light source can be illuminated to the whole diffusion panel evenly to be evenly mixed with LED light source light which is directly illuminated to the diffusion panel, and even light rays of light colors or color rendering indexes that we want are generated, accordingly, the number of the LED light sources is reduced greatly, and the lamp cost is further reduced.
Description
Technical field
The present invention relates to a kind of light fixture, relate in particular to a kind of lighting.
Background technology
The LED lighting has photochromic advantage that can flexible modulation.For example, we can adopt white light LEDs mixing monochromatic light to change the spectrum of white light LEDs, to reach the purpose of regulating colour temperature or improving colour rendering index.A kind of scheme of the prior art is, the led light source that difference is photochromic is arranged on the light source substrate separately equably, then come mixed light by the diffusion panel that is arranged at the lighting light-emitting window, the quantity of the different photochromic led light source that this technical scheme requires is more, just can reach the uniform purpose of colour mixture.
Summary of the invention
Technical problem to be solved by this invention provides a kind of lighting.
In order to solve above technical problem, lighting of the present invention comprises shell, at least two kinds of led light sources that difference is photochromic, described led light source is installed in the described shell, the light-emitting window of described shell is provided with the diffusion panel, one of them plants the described diffusion panel of the direct directive of light of described led light source, and one of them light of planting described led light source is dispersed the described diffusion panel of directive behind the luminous intensity distribution through lens.
Preferably, the quantity of the described led light source of the described diffusion panel of the direct directive of light is a plurality of, and is evenly distributed in the described shell.
Preferably, the material of described diffusion panel is acrylic.
Preferably, described lighting comprises white LED light source, red-light LED light source and green light LED light source, the described diffusion panel of the direct directive of the light of described white LED light source, the light of described red-light LED light source is dispersed the described diffusion panel of directive behind the luminous intensity distribution through lens, and the light of described green light LED light source is dispersed the described diffusion panel of directive behind the luminous intensity distribution through lens.
Preferably, the quantity of described white LED light source is a plurality of, and is evenly distributed in the described shell.
Operation principle of the present invention is such: lighting of the present invention comprises the photochromic led light source of two or more differences, and one of them light of planting photochromic led light source shines directly on the diffusion panel; One of them plants the light of photochromic led light source through being radiated at comparatively equably after the luminous intensity distribution effect of dispersing of lens on the diffusion panel, thereby the photochromic light of two kinds of differences evenly mix at the diffusion panel, generate the uniform light of the sort of photochromic or colour rendering index that we want.Compare with prior art, make the light of one of them kind led light source disperse the lens of luminous intensity distribution by setting, even the quantity of this photochromic led light source seldom, its light also can shine on the whole diffusion panel comparatively equably, thereby the light with the led light source that shines directly into the diffusion panel mixes, generate the uniform light of the sort of photochromic or colour rendering index that we want, thereby greatly saved the quantity of led light source, thereby reduced the cost of light fixture.
Description of drawings
Fig. 1 is the cutaway view of the lighting of a kind of embodiment of the present invention;
Fig. 2 is the schematic diagram behind the lighting removal diffusion panel among Fig. 1.
The specific embodiment
Shown in Fig. 1-2, lighting as a kind of embodiment of the present invention, comprise shell 2, at least two kind of led light source that difference is photochromic, described led light source is installed in the described shell 2, the light-emitting window of described shell 2 is provided with diffusion panel 1, one of them plants the described diffusion panel of the direct directive of light of described led light source, and one of them light of planting described led light source is dispersed the described diffusion panel of directive behind the luminous intensity distribution through lens.In the present embodiment, described shell 2 is cylindrical, and its inner surface is provided with high reflecting material, and substrate 9 is installed in the inner bottom surface of shell 2, and described led light source is installed on the substrate 9.In the present embodiment, described lighting comprises different photochromic led light sources in 3, respectively that chromaticity coordinates is (0.409,0.394) white LED light source 3, chromaticity coordinates be (0.66,0.33) red-light LED light source 5 and chromaticity coordinates be (0.168,0.726) green light LED light source 6, the colour rendering index of white LED light source 3 is 82.In the present embodiment, the quantity of white LED light source is a plurality of, and is evenly distributed in the shell 2, the described diffusion panel 1 of the direct directive of its light.The quantity of red-light LED light source 5 is 1, and directive spread panel 1 after its rays pass through lens 7 was dispersed luminous intensity distribution.The quantity of green light LED light source 6 is 1, and directive spread panel 1 after its rays pass through lens 8 was dispersed luminous intensity distribution.The light of white LED light source 3 is radiated on the diffusion panel 1 equably, and the light of red-light LED light source 5 and green light LED light source 6 is radiated on the diffusion panel 1 after dispersing luminous intensity distribution through lens equably.The light that aforementioned three kinds of photochromic led light sources of difference send is in the stack of diffusion panel, finally make the chromaticity coordinates of the mixed light that described lighting sends be (0.434,0.406), colour rendering index is 92, thereby obtain the light of the high colour developing of low colour temperature, to satisfy the lighting demand of specific occasion.The material of described diffusion panel 1 is acrylic.Need to prove that in the present invention, different photochromic led light sources refer to send the led light source of different-colour or color light.
Operation principle of the present invention is such: lighting of the present invention comprises the photochromic led light source of two or more differences, and one of them light of planting photochromic led light source shines directly on the diffusion panel; One of them plants the light of photochromic led light source through being radiated at comparatively equably after the luminous intensity distribution effect of dispersing of lens on the diffusion panel, thereby the photochromic light of two kinds of differences evenly mix at the diffusion panel, generate the uniform light of the sort of photochromic or colour rendering index that we want.Compare with prior art, make the light of one of them kind led light source disperse the lens of luminous intensity distribution by setting, even the quantity of this photochromic led light source seldom, its light also can shine on the whole diffusion panel comparatively equably, thereby the light with the led light source that shines directly into the diffusion panel mixes, generate the uniform light of the sort of photochromic or colour rendering index that we want, thereby greatly saved the quantity of led light source, thereby reduced the cost of light fixture.
