Abstract

The present invention provides a lamp head of a soft light LED street lamp, which includes at least one reflective LED bulb; the street lamp connecting device includes a first hinged device for adjusting the pitch angle of the lamp head of the LED street lamp, and a second hinged device for adjusting the LED lamp head. The lateral rotation angle of the lamp head of the street lamp includes an eccentric lens for the LED street lamp, and the light exit surface of the eccentric lens is composed of a left-right symmetrical and front-back asymmetric curved surface. A street lamp using an eccentric lens will form approximately rectangular or elliptical light spots when illuminated vertically, and can form a relatively uniform light spot effect on the road surface. The light source of the present invention is softer and can produce better lighting effects.

Description

technical field [0001] The invention relates to the field of city and road lighting engineering, in particular to a soft light LED street lamp lamp holder. Background technique [0002] As the new light source high-power LED technology is becoming more and more mature, the scheme of using high-power LED as the light source for street lamps is gradually becoming common. Since the light of the LED light source has strong directionality, in order to achieve a better road lighting effect, the general method is to adjust the bending angle of the light pole to change the direction of the light source to meet the road lighting requirements. However, the light emitted by the LED light source is not uniform enough, not soft enough, and the uniformity of illumination is not ideal enough. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a soft light LED street lamp lamp holder. [0004] The present invention is realiz...
