Description

Technical Field

[0001] The utility model relates to the technical field of LED street lamps, in particular to a polarized lens module for LED street lamps and an LED street lamp. Background Art

[0002] LED street lights, or semiconductor lighting, are highly efficient solid-state light sources based on a semiconductor PN junction, capable of emitting light using minimal electrical energy. Under a certain forward bias voltage and injection current, holes injected into the P region and electrons injected into the N region diffuse to the active region, recombine through radiation, and emit photons, directly converting electrical energy into light. As a solid-state cold light source, LED street lights offer environmentally friendly, pollution-free operation, low power consumption, high luminous efficiency, and a long lifespan. Therefore, they are the optimal choice for energy-saving road lighting retrofits.

[0003] After searching, the prior art publication number CN203880605U discloses a polarized lens module and LED street light for LED street lights. The polarized lens module for LED street lights includes a substrate and a plurality of lenses disposed on the substrate. Each lens includes an arc-shaped depression and an arched protrusion. The arc-shaped depression is formed by a plurality of first free-form surfaces smoothly connected, with two adjacent first free-form surfaces being tangent to each other; the arched protrusion is formed by a plurality of second free-form surfaces smoothly connected, with two adjacent second free-form surfaces being tangent to each other; and the cross-section of each lens is crescent-shaped. Light distribution tests have shown that LED street lights using this polarized lens module for LED street lights can illuminate the rectangular light spots required for road lighting, and while ensuring the illumination uniformity required by the standard, it also perfectly solves the problem of "zebra crossings" on the road surface by improving the longitudinal brightness uniformity.

[0004] However, the device and the prior art still have the following defects:

The connection method is complicated and the installed polarizing lens module cannot be quickly removed, which is not conducive to the subsequent maintenance of the LED street lamp and reduces the use effect of the LED street lamp.
