Abstract
The utility model provides a LED lamp, includes lens, reflection of light cup and LED lamp board, and reflection of light cup upper end is connected with lens, and a reflection of light cup lower extreme is connected with the LED lamp board, is equipped with LED light source group on the LED lamp board, and inside LED light source group was in the reflection of light glass lower extreme, the face that moves towards glass lower extreme that reflects light at lens was equipped with a plurality of compound eye lens unit, was ring grain fei nieer face at the another side of lens. Because be equipped with a plurality of compound eye lens unit at the face of lens orientation reflection of light cup lower extreme, be ring grain fei nieer face at the another side of lens, then act on through the spotlight effect of feinieer face and compound eye lens unit's mixed light for smooth colour mixture that the LED light source was compiled and published out is even, spotlight is effectual.
Description
Technical field
The utility model relates to field of LED illumination, is specifically related to a kind of LED.
Background technology
LED as the light source of new generation got most of the attention, have that volume is little, luminous flux is large, all solid state work, compact conformation, green non-pollution, the plurality of advantages such as efficient, energy-conservation.But be half space Lambertian source because its typical case goes out light characteristic, direct application easily causes the shortcomings such as Luminance Distribution is unreasonable, dazzle, so all adopt secondary light-distribution technology to carry out luminous intensity distribution again in usual lamp applications, various LED light lens become optimal secondary light-distribution technology.
Current lens all adopt silica gel or the optical plastic material such as Merlon (PC), polymethacrylates (PMMA) to make, lens-shape is designed by nonimaging optics, the optical effects such as refraction, reflection are utilized to change LED light line injection direction, the light source that LED sends is redistributed, thus obtains the Illumination Distribution of expection.Common secondary light-distribution lens design needs the characteristics of luminescence considering chip itself, for different LED chip or different LED, because chip light emitting characteristic there are differences, after changing chip, just need to redesign to meet same illumination distribution requirements to secondary optical lens, namely the versatility of secondary optical lens has stronger limitation, cause in actual production process, need to design different lens for different chip, this adds increased high lens die sinking cost, be unfavorable for that popularity is applied.In prior art, the light distribution effect of the secondary light-distribution lens of LED lamp neither be very desirable, causes the LED light source sent through secondary light-distribution lens luminous intensity distribution still to there is the uneven technical problem of light dazzle, distribution of light.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of LED that light colour mixture is even, spotlight effect is good that LED light source can be made to send.
In order to solve the problems of the technologies described above, the utility model comprises lens, reflector and LED lamp panel, reflector upper end is connected with lens, reflector lower end is connected with LED lamp panel, LED lamp panel is provided with LED light source group, it is inner that LED light source group is in reflector lower end, and being provided with multiple fly's-eye lens unit at lens towards the face of reflector lower end, is ring grain Fresnel surface at the another side of lens.Because be provided with multiple fly's-eye lens unit at lens towards the face of reflector lower end, be ring grain Fresnel surface at the another side of lens, then by the optically focused effect of Fresnel surface and the mixed light effect of fly's-eye lens unit, the light colour mixture that LED light source group is sent is even, spotlight effect good.
As further improvement of the utility model, in reflector upper end, medial surface is provided with boss, and lens are located on boss.
As further improvement of the utility model, the inwall of reflector is provided with reflecting surface, reflecting surface is made up of several convex reflex blocks equally distributed.
As further improvement of the utility model, described ring grain Fresnel surface is annular gradual change dentation optical surface, and the size of dentation is diminished in the middle part of lens gradually by rims of the lens.
As further improvement of the utility model, described LED light source group comprises red LED light source, yellow LED light source, blue led light source, green LED light source and White LED light source, the LED light source of these five colors is with multiple circular arrangement, the color of two LED light sources adjacent on annular is not identical, and on annular, the LED light source of same color is evenly arranged.
As further improvement of the utility model, described LED light source group comprises red LED light source, yellow LED light source, blue led light source and green LED light source, the LED light source of these four colors is with multiple circular arrangement, the color of two LED light sources adjacent on annular is not identical, and on annular, the LED light source of same color is evenly arranged.
In sum, the utility model has the advantages that the light colour mixture that LED light source can be made to send is even, spotlight effect good.
