The LED heat-dissipating module has a reasonable structure, is made of a preferred aluminum material, and has light weight; moreover, radiating fins are provided with strip-shaped vertical bumps which can be used for enhancing the structural strength, increasing the heat-dissipating area and improving the heat-dissipating effect; furthermore, two adjacent radiating fins are fixed together through a fixing pin, so that high stability is achieved; and a ventilation groove isformed between every two adjacent radiating fins for ventilating, so that heat of the LED lamp can be dissipated quickly, the light decay speed is lowered, and the service life is prolonged greatly.

Description

technical field [0001] The invention relates to a lighting fixture manufacturing technology, in particular to an efficient and environment-friendly heat dissipation method for an LED heat dissipation module and the LED heat dissipation module. Background technique [0002] Most of the traditional road lamps use high-power mercury lamps, metal halide lamps or high-pressure sodium lamps as light sources. High, lighting effects are unsatisfactory in terms of color rendering and anti-glare performance. At the same time, the development of semiconductor light-emitting diodes (LEDs) is extremely rapid. In recent years, the luminous efficiency of some LEDs has greatly exceeded that of incandescent lamps, and even exceeded that of fluorescent lamps. Compared with the traditional floodlight electric light source, the LED light source is basically non-toxic, non-electromagnetic pollution, and has many advantages such as small size, low energy consumption, high luminous efficiency, re...

Problems solved by technology

Excessive chip temperature will bring many problems, such as accelerating device aging, accelerating the speed of LED light decay, shortening the service life, and even causing the chip to burn

[0004] At present, the heat sinks for LED heat dissipation on the market are usually extruded, die-casted, machined or cut to solve the heat dissipation. Generally, they are large in size, heavy in weight, use more materials, and have high cost. Those who do not have enough understanding of thermal conduction, heat convection and heat radiation, the designed radiators are often not very reasonable, so many problems are caused, such as heat conduction is good, but heat convection is not good; heat convection is good, heat conduction is not good , has a great impact on the heat dissipation of LED light sources. For example, the weight of LED lamps cannot be effectively reduced, the heat dissipation problem of LED lamps cannot be solved well, and it is difficult to achieve high-power LED lamps. The service life of LED also has a great influence
