Problems solved by technology

The traditional structure is to fix the light source module or power module in the housing, and the housing cover is fixed with screws. During operation, the screw needs to be removed in the air to open the lamp body, which is difficult to operate.
Existing light source modules generally consist of radiators, LED light panels, and lenses. After the LED light-emitting chip is damaged, it can only be replaced as a whole, which has poor flexibility and high maintenance costs.
The existing lamp body joint cannot be rotated, and the angle cannot be adjusted according to actual needs

Abstract

The invention discloses an LED street lamp and relates to a road traffic lighting technology. The LED street lamp comprises a street lamp joint, a power assembly and a light source assembly, wherein the street joint is rotatably and adjustably fixed with the power assembly in a positioning groove through an inner toothed ring structure and an outer toothed ring structure; a surface cover of the power assembly is provided with a light-operated module, and a power module is fixed in a clamping groove of a power cavity through a per se fixing plate and butted against the light source module; the surface cover is connected and fixed with the main body of the power assembly though a hinge and a hook; the light source assembly comprises two supporting arms fixed on the side wall of the power cavity and a plurality of light source modules which are bridged between the two supporting arms and positioned on supporting platforms of the supporting arms; and the end parts of the other ends of the supporting arms are fixed into a whole through an end cover. The LED street lamp is quite convenient to assemble and disassemble, when fragile parts are replaced during maintaining, other parts cannot be influenced, and the supporting arms of different lengths can be used according to actual requirements so as to arrange different quantities of light source modules. The lamp has optimized structure, convenient mounting angle regulation and low use and maintenance cost.

Description

technical field [0001] The invention relates to an LED street lamp, which is used for road traffic lighting. Background technique [0002] LED street lamps generally include two parts: a power supply and a light source module. The power supply module has a high failure rate and is the most prone to failure component in the lamp body. The traditional structure is to fix the light source module or power module in the housing, and the housing cover is fixed with screws. During operation, the screw needs to be removed in the air to open the lamp body, which is difficult to operate. Existing light source modules generally consist of radiators, LED light panels, and lenses. After the LED light-emitting chip is damaged, it can only be replaced as a whole, which has poor flexibility and high maintenance costs. The existing lamp body joint cannot be rotated, and the angle cannot be adjusted according to actual needs. These problems existing in the existing LED street lamps are the ...
