Heat dissipation assembly structure of LED (Light Emitting Diode) street lamp

Abstract

The invention relates to a heat dissipation assembly structure of an LED (Light Emitting Diode) street lamp. The heat dissipation assembly structure consists of baffles and a heat dissipation substrate; the heat dissipation substrate is semicylindrical; the cambered surface of the heat dissipation substrate is provided with heat dissipation ribs; a groove is formed in a plane of the heat dissipation substrate; the heat dissipation substrate is in a shape of a cavity; heat conduction ribbed plates are arranged in the cavity; the cavity are divided into at least two independent spaces by the ribbed plates. When the heat dissipation assembly structure is used, according to a road situation and the power requirement, one or more than one LED luminescence component is assembled according to the technical solution; the baffles are arranged at two ends of the one or more than one LED luminescence component to enable the one or more than one LED luminescence component to form a lamp holder; luminescence bars of the one or more than one LED luminescence component are reasonable in layout; air convection intensity is enhanced by brightness and light spot patterns generated by the lamp holder during working; dust and impurities deposited in a heat dissipation groove of a lamp base are cleared by natural wind or under scouring action of rainwater, so that heat dissipation efficacy of a heat dissipation base is realized and enhanced. The heat dissipation assembly structure has the advantages that cost is low, an assembly process is simple, light distribution is flexible, a heat dissipation effect is good 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.

The high-power LED light source for semiconductor lighting will eventually completely replace the traditional light source. 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.
