Example Embodiment

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] see figure 1As shown, a LED lamp heat sink in this embodiment has a circular structure as a whole, including a circular base 1, and a number of cooling fins 2 are arranged on the periphery of the circular base 1. The heat dissipation fins 2 are radially and evenly spaced, and there are 24 heat dissipation fins 2 in total. The rubber strip mounting seats 3 are arranged on the periphery of the circular base 1 in equal parts, and between two adjacent rubber strip mounting seats 3 There are 6 heat dissipation fins 2, and the rubber strip mounting seat 3 is arranged radially, and the length is consistent with the heat dissipation fins 2. Two cavities are provided on the rubber strip mounting seat 3 for setting the rubber strips. On the one hand The weight of the radiator can be reduced, the material can be saved, and at the same time, it ca...

Abstract

The invention relates to an LED lamp radiator. The radiator comprises an annular base, a plurality of radiating fins are arranged on the periphery of the annular base, the radiating fins are evenly arranged at intervals in a radial shape, adhesive tape mounting bases are arranged on the periphery of the annular base at equal intervals, the adhesive tape mounting bases are arranged in the radial direction, the inner surface of the annular base is arranged to be sawtooth-shaped, a pair of electric heating tube mounting seats is arranged on the inner surface, the two electric heating tube mounting seats are oppositely arranged along the same diameter, and meanwhile, small radiating fins are symmetrically arranged on the two sides of the outer surfaces of the electric heating tube mounting seats. The preparation process mainly comprises the steps of pre-production preparation, cast ingot heating, extruding, stretch straightening, fixed-length saw cutting and sampling, artificial aging, acceptance check and handover. According to the preparation method of the radiator, the control is carried out through reasonable process steps and process parameters, so that the preparation success rate of the complex radiator is improved.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of LED modules, and in particular relates to a heat dissipation structure, a heat sink for an LED lamp and a processing method thereof. Background technique [0002] At present, LED light sources are widely used in new energy-saving light sources. Compared with discrete LED light sources, COB structure LED light sources have the advantages of high luminous efficiency and simple heat dissipation structure. However, the luminous efficiency and life of COB structure light sources are not as good as The temperature of the light source is seriously related. The higher the temperature, the lower the luminous efficiency and the lower the lifespan. The key design of LED lamps is heat dissipation design, trying to reduce the temperature of LED light source. High-power LEDs generate a lot of heat, and various traditional cooling technologies such as conventional-sized liquid single convection cool...
