Heat dissipation assembling structure of light-emitting diode (LED) street lamp

Abstract

The invention relates to a heat dissipation assembling structure of a light-emitting diode (LED) street lamp, which is composed of a baffle and a heat dissipation substrate. The heat dissipation substrate is in a semi-cylindrical shape, the cambered surface of the heat dissipation substrate is provided with a heat dissipation rib, the plane of the heat dissipation substrate is provided with a groove, the heat dissipation substrate is in a cavity shape, heat-conducting rib plates are arranged in the cavity and divide the cavity into at least two or more than two independent spaces, and the baffle is roundly combined with one end of a radiator. When the heat dissipation assembling structure of the LED street lamp is in use, an LED light-emitting assembly is assembled according to road conditions, the requirements for power and the technical scheme. The baffles are added to two ends of each LED light-emitting assembly so that one or a plurality of LED light-emitting assemblies form a lamp cap, a light-emitting strip is arranged reasonably, and the strength of cross-ventilation is reinforced during work. Dust and sundries which are accumulated in a lamp holder heat-dissipation groove are eliminated under the flushing effects of natural air or rain water, the heat dissipation effect of a heat dissipation base is achieved and enhanced, and the heat dissipation assembling structure of the LED street lamp has the advantages of being low in cost, simple in assembling process, flexible in light distribution, good in heat dissipation effect and the like.

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED street lamp heat dissipation assembly structure with good heat dissipation effect and long service life. Background technique [0002] As we all know, with the continuous innovation and development of science and technology. High-power LED light sources for semiconductor lighting will eventually completely replace traditional light sources. The performance and life are inversely proportional to the working junction temperature of the LED light source. Therefore, when in use, a good heat dissipation design is required to reduce the working temperature of the LED light source and then reduce its junction temperature. Street lamps need good airtightness in harsh outdoor environments To achieve the effect of waterproof and dustproof, this kind of airtight environment is not conducive to the heat dissipation of LED light source, thus affecting the performance and service lif...

High-power LED light sources for semiconductor lighting will eventually completely replace traditional light sources. The performance and life are inversely proportional to the working junction temperature of the LED light source. Therefore, when in use, a good heat dissipation design is required to reduce the working temperature of the LED light source and then reduce its junction temperature. Street lamps need good airtightness in harsh outdoor environments To achieve the effect of waterproof and dustproof, this kind of airtight environment is not conducive to the heat dissipation of LED light source, thus affecting the performance and service life of LED street lamps. The radiator of existing high-power LED lamps is generally a solid core body, and the radiator is external The "fish gill" shape heat sink has the disadvantages of heavy weight, waste of materials, poor heat dissipation, etc.
