Abstract

The invention discloses a planar light extracting LED street lamp comprising a lamp holder, a spacer fixed on the lamp holder, a lamp housing screwed on the spacer and a screw cap arranged on the lamp housing, wherein a circuit board is arranged in the spacer; a single LED lamp is arranged at the front end of the lamp holder and is connected with the circuit board; the LED lamp comprises a lamp panel, a bulb and a double-peak optical lens; the bulb and the double-peak optical lens are arranged on the lamp panel; the middle of the double-peak optical lens is sunken; the bulb faces towards the sunken part in the middle of the double-peak optical lens; and the LED lamp is covered by a non-lighttight cover. The LED street lamp has the characteristics of uniform light distribution, high utilization ratio of light energy, good heat dissipation effect and long use time.

Description

technical field [0001] The invention relates to a diode street lamp, in particular to a plane light-emitting LED street lamp. Background technique [0002] Existing LED street lamps usually cover the diode beads with a convex lens to process the light emitted by the diodes, but this processing method will cause problems such as uneven distribution of light and low utilization of light energy. In addition, some existing LED street lamps still have The heat dissipation effect is poor and the use time is short. Contents of the invention [0003] The object of the present invention is to provide a plane light-emitting LED street lamp. [0004] The present invention aims to solve the problems of uneven light distribution, low utilization rate of light energy, poor heat dissipation effect and short service time of the existing LED street lamps. [0005] For realizing the purpose of the present invention, the technical scheme that adopts is: [0006] It includes a lamp holder,...
