The LED lamp comprises a light source, wherein a lens is arranged on the outer side of the light source and comprises an incident surface and an emergent surface, a plurality of PC particles are filled on the lens between the incident surface and the emergent surface, supports fixedly connected with the lens are arranged at two ends of the lens, and a film is arranged on the connecting surfaces of the supports and the lens.
Description
Technical Field
The utility model relates to a street lamp technical field specifically is a LED tunnel lamp lens.
Background
The light distribution design of the optical component of the tunnel lamp of the existing tunnel lamp generally adopts two modes, one mode is total reflection type light distribution, namely, the light source directly projects part of light, and the rest light is reflected by a reflection type outer cover and then is projected by glass; the other type is a modular PC lens, the optical component is a transparent optical PC, the whole module is of an integral structure, and light rays are all projected onto an irradiation surface through the lens and the PC part.
The main defects of the prior art are as follows: (1) the direct projection part of the reflective light distribution is directly projected through the glass, so that the light of the light source is not subjected to optical light distribution, the light distribution uniformity of the reflective light distribution only depends on the light distribution of the light source, and the ideal effect cannot be achieved; (2) the light of the reflective light distribution part is directly reflected by the reflecting surface, so that the light loss cannot be further controlled, and the light emitting efficiency of the lamp is not improved; (3) the reflective light distribution is characterized in that due to the special light distribution mode, the structure size of the reflective light distribution depends on the size of a light source seriously, and a reflective optical accessory is not easy to be completely matched with the light distribution of the light source and has higher design difficulty; (4) although the light distribution type design aspect of the integrated PC structure is better than that of a reflection type, the full-transparent PC structure also causes difficulty in controlling glare in special occasions.
Therefore, it is necessary to develop a lens of an LED tunnel lamp to solve the problems of the prior art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a LED tunnel lamp lens, can make full use of PC optical lens and the advantage of reflective grading, realize high homogeneity on the tunnel illumination grading, reduce the glare effect, promote lamps and lanterns light source luminous efficiency to solve the problem that proposes among the above-mentioned background art.
