The invention adopts novel materials and a fire-new process, so the invention has a high-efficiency unique heat radiation structure, and the heat radiation efficiency is high.

Description

technical field [0001] The invention relates to a street lamp, in particular to a novel low-cost, high-efficiency, heat-dissipating, high-power LED street lamp and a production process thereof. Background technique [0002] At present, the traditional LED high-power street lamps have the following defects: (1) The lamp beads of the street lamps are installed on the PCB board. Since the PCB board is prone to heat accumulation, it is not easy to conduct heat and dissipate heat. When the chip conducts light and generates heat, its heat passes through Silver glue and silica gel are transferred to the aluminum substrate, and then transferred to the heat dissipation shell through thermal silica gel. The heat conduction process is complicated, resulting in the formation of thermal resistance layer by layer, resulting in junction temperature and light decay problems of the chip. The heat on the lamp bead chip cannot be transferred out in time, which greatly shortens the service life...

[0002] At present, the traditional LED high-power street lamps have the following defects: (1) The lamp beads of the street lamps are installed on the PCB board. Since the PCB board is prone to heat accumulation, it is not easy to conduct heat and dissipate heat. When the chip conducts light and generates heat, its heat passes through Silver glue and silica gel are transferred to the aluminum substrate, and then transferred to the heat dissipation shell through thermal silica gel. The heat conduction process is complicated, resulting in the formation of thermal resistance layer by layer, resulting in junction temperature and light decay problems of the chip.

[0003] Due to the above-mentioned defects in the structure of traditional LED high-power street lamps, the production process is complicated, the production efficiency is low, the quality is unstable, the cost is high, and the promotion is difficult.
