Accompanying drawing explanation
Fig. 1 is one embodiment of the present of invention.
Fig. 2 is another embodiment of the presently claimed invention.
Detailed description of the invention
The following stated is only the detailed description of the invention of invention, does not therefore limit protection scope of the present invention.
The first embodiment of the present invention is referring to Fig. 1, and a kind of light filtering structure, including light source 1, heat shield 2 and optical filtering Colour-changing disk 3, light source 1 is used for irradiating optical filtering Colour-changing disk 3, and light source 1 can use LED light source or non-LED light source；Optical filtering Colour-changing disk 3 is positioned at the front of light source 1, optical filtering Colour-changing disk 3 is provided with light filter 31, the light that light source 1 is launched can obtain the light of different colours after the light filter 31 on optical filtering Colour-changing disk 3, light filter 31 annular is arranged on optical filtering Colour-changing disk 3, light filter 31 near the one end at optical filtering Colour-changing disk 3 center as the inner of light filter 31, the inner of this light filter 31 is prominent to light source side, makes light filter 31 have specific angle of inclination relative to the front end face of light source 1；Heat shield 2 is arranged on light source 1 and the centre of optical filtering Colour-changing disk 3；Heat shield 2 has the angle of inclination relative to light source 1；The light that light source 1 sends, from the central authorities to heat shield 2 through being irradiated on the optical filter 31 optical filtering Colour-changing disk 3.The thickness of heat shield 2 is gradually increased from center to edge, and its change curve can be straight line, it is preferred that for the such as camber line shown in profile 4.By such setting, light source 1 light sent, passing through from the center of heat shield 2, owing to its center is relatively thin, heat shield 2 is more weak for the stop of light, and the transmitance of light is higher.Through the light of heat shield 2, part is reflected by optical filtering Colour-changing disk 3, and owing to light filter 31 has inclination angle, the light of its transmitting is upwards dispersed, and from the edge traverse that heat shield 2 is thicker, thus it stops relatively strong, reflection light is difficult to affect light source through heat shield.Preferably, at heat shield 2, reflecting layer can be set in the face of the side of optical filtering Colour-changing disk 3, thus the reflection light of optical filtering Colour-changing disk 3 is reflected optical filtering Colour-changing disk again, thus increasing the brightness of emergent light, this reflecting layer can be arranged at outside the area of the light source irradiation of heat shield 2.Preferably, due to the first half being just radiated at heat shield of optical filtering Colour-changing disk reflection, it is possible to this reflecting layer to be positioned at the first half of described heat shield.Preferably, it is possible to described reflecting layer is set to parallel with described light filter so that reflection light is irradiated on described light filter better.
Another embodiment of the presently claimed invention is referring to Fig. 2, and a kind of light filtering structure, including light source 1, heat shield 2 and optical filtering Colour-changing disk 3, light source 1 is used for irradiating optical filtering Colour-changing disk 3；Optical filtering Colour-changing disk 3 is positioned at the front of light source 1, optical filtering Colour-changing disk 3 is provided with light filter 31, the light that light source 1 is launched can obtain the light of different colours after the light filter 31 on optical filtering Colour-changing disk 3, light filter 31 annular is arranged on optical filtering Colour-changing disk 3, light filter 31 near the one end at optical filtering Colour-changing disk 3 center as the inner of light filter 31, the inner of this light filter 31 is prominent to light source side, makes light filter 31 have specific angle of inclination relative to the front end face of light source 1；Heat shield 2 is arranged on light source 1 and the centre of optical filtering Colour-changing disk 3；Heat shield 2 has the angle of inclination relative to light source 1；The light that light source 1 sends, from the central authorities to heat shield 2 through being irradiated on the optical filter 31 optical filtering Colour-changing disk 3.Heat shield 2 center has perforate 4, and wherein the area of perforate 4 is equal to the light source 2 irradiated area on heat shield 4.By such setting, light source 1 light sent, pass through from the center drilling 4 of heat shield 2, the impact of heat shield 2 will not be subject to.Through the light of heat shield 2, part is reflected by optical filtering Colour-changing disk 3, and owing to light filter 31 has inclination angle, the light of its transmitting is upwards dispersed, traverse beyond heat shield 2 perforate 4, is subject to the stop of heat shield 2, thus avoiding reflection light to affect light source.Preferably, it is possible to reflecting layer 21 is set in the side in the face of optical filtering Colour-changing disk 3 of heat shield 2, thus the reflection light of optical filtering Colour-changing disk 3 is reflected optical filtering Colour-changing disk 3 again, thus increasing the brightness of emergent light.Preferably, it is possible to reflecting layer 21 is set to parallel with light filter 31 so that reflection light is irradiated on light filter 31 better.
As another aspect of the present invention, it is provided that a kind of decor LED, it has the light filtering structure in above-described embodiment.
Embodiment described above only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.
