The light source module is located side by side between the two support arms, and the bridge is placed on the support platforms of the two support arms.

The above-mentioned support arm is a section of metal pipe, and the outside of the section is semicircular.

The above-mentioned light source module includes a lens pressing plate, a lens array, an LED lamp board and a radiator. The LED lamp board is attached to the surface of the radiator, the lens array is covered on the light bulb of the LED lamp board, and the lens pressing plate is covered on the lens and pressed against the edge of the lens. The side edge of the lens pressure plate surrounds the side of the heat sink, and the end of the heat sink is provided with mounting holes and fixed on the support platform through screws.

The present invention also provides a light source module of an LED street light source assembly, including a lens pressing plate, a lens array, an LED lamp board and a radiator, the LED lamp board is attached to the surface of the radiator, the lens array is covered on the bulb of the LED lamp board, and the lens pressing plate The cover is on the lens and pressed on the edge of the lens, the edge of the lens pressing plate with the side surrounds the side of the heat sink, and the end of the heat sink is provided with a mounting hole.

The radiator is composed of a radiator substrate and a plurality of fins arranged and distributed vertically to the substrate.

The above substrate has a cuboid structure.

The present invention also provides a heat sink for the LED street light source module. The heat sink is composed of a heat sink base plate and a plurality of heat sink fins arranged and distributed vertically to the base plate.

The beneficial effect of the present invention is that the light source assembly is composed of a plurality of light source modules, the modules are located side by side between two support arms and bridged on the support platforms of the two support arms, the two ends of each module are fixed to the support platform by screws, and the modules There is no connection between them, and maintenance can be performed without affecting other modules. The length of the support arm can be changed during design, and the length of the support arm can be determined according to requirements. When the support arm is longer, more modules can be installed to suit the needs of different places. Easy maintenance.

The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

Detailed ways

In order to understand the present invention and enable those skilled in the art to realize the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to FIG. 1 , the LED street lamp includes a street lamp connector 10 , a power supply assembly 20 , and a light source assembly 30 .

Referring to Fig. 2, the light source assembly 30 includes two support arms 31, 32 respectively fixed on the side walls 200, 201 of the power supply cavity of the above-mentioned power supply assembly and a plurality of light source modules 33 fixed between the two support arms, two The other ends of the support arms 31 and 32 are fixed integrally by an end cover 34 .

Referring to FIG. 2 , the support arm 31 is a section of metal pipe with a semicircular cross-section outside, and a support platform 35 is arranged inside the support arm, and a plurality of installation holes are arranged on the support platform 35 .

Referring to Fig. 4, Fig. 5a, Fig. 5b, the light source module 33 includes a lens pressing plate 301, a lens array 302, an LED lamp board 303 and a radiator 304, the LED lamp board 303 is attached to the surface of the radiator 304, and the lens array 302 is covered on the LED lamp board On the light bulb of 303, the lens pressing plate 301 is covered on the lens and is pressed on the edge of the lens, the edge 305 with the side of the lens pressing plate 301 surrounds the side of the heat sink 304, and the end of the heat sink is provided with a mounting hole 306 and fixed on it by screws.
