Description

technical field [0001] The invention relates to a lamp, in particular to an LED lamp. Background technique [0002] Existing street lamps generally adopt the structure of reflection and transmission to produce a circular bright spot on the road surface, and the light spots of the street lamps on the same side are spread along the road in turn to meet the lighting requirements of the road surface. The light distribution of existing lamps has the following defects: First, A single high pole light gets a circular light spot with a bright center and dark surroundings on the road surface, and there is unevenness in the brightness of a single light spot in the vertical and horizontal directions. Secondly, the adjacent light spots are arranged in sequence to form the overall illuminance of the road surface. Dark areas are inevitably generated at the junctions of circular light spots. Under the premise of not providing lighting density, the dark areas at the intersection of light sp...

[0002] Existing street lamps generally adopt the structure of reflection and transmission to produce a circular bright spot on the road surface, and the light spots of the street lamps on the same side are spread along the road in turn to meet the lighting requirements of the road surface. The light distribution of existing lamps has the following defects: First, A single high pole light gets a circular light spot with a bright center and dark surroundings on the road surface, and the brightness of a single light spot has unevenness in the vertical and horizontal directions

Secondly, the adjacent light spots are arranged in sequence to form the overall illuminance of the road surface. Dark areas are inevitably generated at the junctions of circular light spots. Under the premise of not providing the density of lights, the dark areas at the junction of light spots become the limit to improve the uniformity of road brightness. bottleneck

In order to ensure high illuminance uniformity, the density of lighting is often increased, that is, adjacent spots are overlapped, so the power consumption is relatively large

Therefore, the existing LED lamps simply arrange multiple LED lamps together without using the optical response of the quadric surface, and cannot effectively use the outgoing light energy of the LED for charging and discharging.
