Problems solved by technology
[0003] The exposed PC lens is easy to be contaminated with dust and oil, and the PC or PMMA material is prone to aging and yellowing. The two factors together aggravate the light decay and seriously reduce the luminous flux maintenance rate, thus affecting the road lighting effect.
[0004] The light transmittance of the PC lens is about 90%, and the light loss is serious
When the requirements for high light efficiency are strict, through conventional adjustments and improvements, the light effect improvement will become less and less significant, and the improvement will not move when encountering a bottleneck

Embodiment 1
[0033] This embodiment discloses a distributed light guide system with double reflection characteristics, which can be used for lighting fixtures, such as garden lights or street lights, etc., such as figure 1 , 2 , 3, the whole lamp equipped with this light guide system includes protective glass 1, double reflection light guide 2, light source board 3, spring clip 4, circuit board 5, radiator 6, safety clip 7, respirator 8 and Waterproof joint 9. The radiator 6 includes a hollow cavity and heat sinks located outside the hollow cavity. The hollow cavity is the light source cavity of the whole lamp. The light source board 3, the spring clip 4, the circuit board 5, and the double-reflection light guide 2 are all arranged on the light source. In the cavity, the light source board 3 is fixed by the spring clamp 4, the double reflection characteristic light guide 2 is installed on the light source board 3, there is a groove for coating glass glue on the top of the hollow cavity of...

The invention discloses a double-reflection characteristic distributed cross light guide system, which includes a light source board, a radiator, a double-reflection characteristic light guide and a spring clip, the light source board is fixed on the radiator through the spring clip, and the double-reflection characteristic light guide is installed On the light source plate, it is used for diffuse reflection and specular reflection of the light emitted by the light source plate; the light guide with double reflection characteristics includes a plurality of reflective cavities distributed in an array, and the reflective cavity is a concave cavity, and on the wall of the reflective cavity There are a plurality of light outlet holes connected to the light source plate for the light output of the light source. The inner wall of the reflective cavity forms a curved light guide surface for the light output from the light source. Each light guide curved surface is configured with different reflection characteristics. light needs. The present invention avoids the serious light decay caused by dust absorption and yellowing of the PC lens, and the problems of low light efficiency caused by low light transmittance.
Description
technical field [0001] The invention relates to a light guide system, in particular to a distributed cross light guide system with double reflection characteristics, which is used for lighting lamps and belongs to the technical field of lighting. Background technique [0002] At present, garden lights and street lighting generally use modular PC lens refraction light distribution to meet the needs of road lighting, but PC lens refraction light distribution has the following problems: [0003] The exposed PC lens is easy to be contaminated with dust and oil, and the PC or PMMA material is prone to aging and yellowing. The two factors together aggravate the light decay and seriously reduce the luminous flux maintenance rate, thus affecting the road lighting effect. [0004] The light transmittance of the PC lens is about 90%, and the light loss is serious. When the requirements for high light efficiency are strict, through conventional adjustments and improvements, the light ...
