In the present invention, the integral type that laser street lamp reflecting shade is made up of reflector, reflective surface portion and rake fills
Put, ensure that integrally-built do not fall off；Minute surface is coated with the inside of rake, ensure that the reflection of laser beam is utilized, is protected
The maximum reflection for having demonstrate,proved luminous energy utilizes；It is 35 °~40 ° that rake I is angled with reflector central shaft institute, rake II with it is reflective
Angled cup central shaft institute is 10 °~15 °, and it is 65 °~70 ° that rake III is angled with reflector central shaft institute, be ensure that sharp
The utilization rate of light light beam.
By adopting the above-described technical solution, the present invention has the advantage that：Cost is cheap, and it not only utilizes laser
Rate up to 92.5%, and it is reasonable in design, structure is attractive in appearance and light is evenly distributed, good illumination effect.
