Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and in particular to an LED street lamp module. Background Art

[0002] Street lights refer to lamps that provide lighting for roads. They generally refer to lamps within the road surface lighting range in traffic lighting. Street lights are widely used in various places where lighting is needed.

[0003] The Chinese patent with announcement number CN204513111U discloses a lighting street lamp, which includes a light emitting diode LED driver with multiple dimming modes, multiple asymmetric optical light distribution lenses, an electrical box and an aluminum substrate, wherein the aluminum substrate is provided with an LED light source, the asymmetric optical light distribution lens is detachably connected to one side of the aluminum substrate, and the LED light source is located between the asymmetric optical light distribution lens and the aluminum substrate, and the aluminum substrate is fixedly connected to one end of the electrical box. The utility model adopts an LED driver with multiple dimming modes, which can drive the LED light source to automatically adjust the brightness of the light emitted by the light source in environments with different brightness, and is equipped with an asymmetric optical light distribution lens to perform secondary optical processing on the light emitted by the light source, so that the lighting street lamp has the characteristics of high light efficiency, uniform brightness, good color rendering, etc., and is highly practical.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff used the cooperation of the lens pressure plate and the optical light distribution lens to cover the LED light source on the aluminum substrate, thereby realizing the diffuse lighting of the LED light source. However, the optical light distribution lens and the lens pressure plate are separately arranged, and according to the attached figure of the specification, the optical light distribution lens is installed between the aluminum substrate and the lens pressure plate. As a result, if the LED light source needs to be maintained, the lens pressure plate and the optical light distribution lens need to be removed in turn, and the maintenance steps are cumbersome. In the prior art, the heat emitted by the LED light source needs to pass through the double obstacles of the optical light distribution lens and the lens pressure plate. It also takes a long time to dissipate the heat by the one-way heat conduction of the lamp frame and the thermal conductive silicone sheet, so that the LED light source needs to be maintained in a high temperature environment for a long time. This will also affect the luminous efficiency of the LED light source to a certain extent and shorten the service life of the LED light source. Summary of the invention
