Street lamp adopting LED light source

Abstract

A street lamp adopting an LED light source comprises a lamp housing, a reflecting shade, a light-emitting port, a light-transmittable shade and an LED light source module, wherein the reflecting shade is arranged in the lamp housing; the light-emitting port is arranged on the lamp housing; the light-transmittable shade is arranged at the light-emitting port; the LED light source module is fixed in the reflecting shade, and comprises a first stamping sheet metal, a second stamping sheet metal, a third stamping sheet metal, a plurality of LED chips and a control circuit board; the LED chips arearranged on the second stamping sheet metal; the control circuit board is connected with the LED chips; the second stamping sheet metal is provided with a mounting port used for fixing the control circuit board; a plurality of openings for limiting an area with point fluorescent powder glue are formed on the third stamping sheet metal; the LED chips are stuck on the second stamping sheet metal inpositions corresponding to the openings; and the first stamping sheet metal, the second stamping sheet metal and the third stamping sheet metal are fixed with one another through a connecting mechanism. The street lamp adopting the LED light source has the advantages of good heat dissipation performance, low cost and long service life.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a street lamp with a light-emitting diode light source. Background technique [0002] With the construction of urbanization, street lamps can be seen everywhere. Street lighting not only accelerates the pace of urbanization, but also promotes the rapid development of municipal construction. As a window of urban image, landscape lighting, road lighting construction and management have also achieved unprecedented development. Street lights provide a safe and orderly environment for residents to travel at night. [0003] Compared with traditional street lights, LED street lights not only have the advantages of good chromaticity, maintenance-free, and long life, but more importantly, they are more energy-efficient than traditional street lights. At present, the light-emitting diode light source and power driver of LED street lamps are mostly separated, and some of them are driven ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a street lamp with light-emitting diode light source, which aims at overcoming the shortcomings of the existing light-emitting diode light source and power driver, which occupy a large space, have low voltage efficiency, and voltage fluctuations are likely to cause current fluctuations. In order to overcome the shortcomings of poor heat dissipation performance of existing LED street lamps
