Convenient, the heat dissipation structure of the whole light source module is reasonable, the heat dissipation effect is better, and the overall service life of the lamp body is long.

The technical scheme that the present invention adopts is as follows:

A street lamp with adjustable lighting angle, including a lamp module, a support rod, a front baffle, a rear baffle and a connecting rod, the lamp module includes a radiator, a heat conducting plate, an LED light source, a lens and its components, The LED light source is arranged on the front of the heat conducting plate, and the lens and its components are arranged in front of the LED light source. The heat sink is composed of a plurality of heat sinks, and the heat sink is provided with a plurality of parallel reinforcement ribs, and heat dissipation holes are arranged on both sides of the reinforcement ribs. The lower side of the heat dissipation hole has buckle ears protruding outward, and the adjacent heat sinks are inserted into the heat dissipation holes through the buckle ears to fix them. The back of the heat conducting plate has a plurality of fixing grooves continuously connected with the heat dissipation fins, and the heat dissipation fins are inserted into the fixing grooves. Among them, baffles are provided on the outer sides of both ends of the radiator, and the baffles and the heat conduction plate are fixedly connected by bolts, and the two ends of the front of the heat conduction plate are provided with connecting rod placement slots, and the plurality of lamp modules are arranged side by side. The rod is arranged in the connecting rod placement groove, and the front and rear sides of the multiple lamp modules are provided with baffles, the rear ends of the rear baffles are connected to the support rods, and the rear ends of the support rods are rotatably connected to the main rod.

The connecting rod is in contact with inclined surfaces on both sides of the connecting rod placing groove.

A slot is provided at the contact between the buckle ear and the heat sink.

The buckle ear is composed of a right-angle plate, wherein the middle of the right-angle plate has a side extending outward, and the two sides of the side are separated from the two sides.

Compared with the prior art, the beneficial effects of the present invention are as follows:

The invention improves the structure of the heat sink in the light source module of the lamp. The heat sink is connected by a plurality of heat sinks, and the heat sink is inserted and connected with the heat conduction plate to increase the contact area, improve the heat dissipation effect, and quickly export the heat generated by the light source. The heat dissipation effect is good through the cooling fins on the radiator. The lamp light source module is reasonably assembled with the street lamp bracket structure. The light source module is easy to install and disassemble. After multiple lamp modules are combined, the rear end is connected to the support rod, and the rear end of the support rod rotates. Connect the main pole to facilitate the adjustment of the lighting angle of the street light.
