Abstract

The invention discloses a planar light extracting LED projection lamp comprising a lamp body, an aluminum substrate arranged on the front of the lamp body and a driving power module arranged at the back of the lamp body, wherein LED lamps are distributed on the aluminum substrate and are connected with the driving power module; each 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 has a sunken structure; and the bulb faces towards the sunken structure in the middle of the double-peak optical lens. 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 floodlight, in particular to a plane-emitting LED floodlight. Background technique [0002] Existing LED floodlights usually cover the diode beads with a convex lens to process the light emitted by the diodes. However, this processing method will cause problems such as uneven distribution of light and low utilization of light energy. In addition, some existing LED floodlights The light lamp also has the problems of poor heat dissipation and short service life. Contents of the invention [0003] The object of the present invention is to provide a planar light-emitting LED floodlight. [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 use time of the existing LED projecting light. [0005] For realizing the purpose of the present invention, the technical scheme that adopts is: [0006] It includes a lamp ...
