Description

technical field [0001] The invention relates to an LED lamp with a cooling device and a processing method thereof, which belongs to the technical field of LED lighting and is especially suitable for street lamps. Background technique [0002] The lamp cap of a known LED street lamp is composed of LED particles, a circuit, a light source module equipped with a lens, a heat sink, a lamp housing and a power supply, wherein the light source and power supply are generally integrated in a relatively closed lamp housing. Because it is used as a street light, high-power LEDs are usually required, and high-power LEDs will emit a lot of heat when they work. If the heat cannot be discharged in time, the temperature of the PN junction of LED particles will increase significantly, which greatly affects the service life of LEDs. And color rendering, these heats also have a negative impact on the power supply, therefore, how to quickly and efficiently export the heat generated by LED parti...

AI Technical Summary

Problems solved by technology

[0004] 1. The heat sink technology commonly used in existing LED street lamps is not mature enough. Low-end heat sinks are rough in manufacture and poor in heat dissipation, and cannot achieve the purpose of rapid heat conduction; high-end heat sinks are too expensive and limited in use. Although the heat dissipation effect is good, it is not suitable for street lamps used in the open air

[0005] 2. The known finned radiators are air-cooled or water-cooled. These radiators are not suitable for street lamps

[0006] 3. Although the heat dissipation effect of the known heat pipe radiator is relatively good, but due to the greatly increased cost, and the harsh outdoor environment, the heat pipe is easily damaged, so the use is also limited

[0007] 4. The structure of the real radiator cannot be matched and installed with other modules in the lamp body of the real street lamp, so it is impossible to achieve the optimal heat dissipation effect

[0008] After retrieving Chinese patents, there are several articles on the invention of LED lamps with heat sinks, but they are different from the technical solutions provided by the present invention; they do not involve the processing method of the present invention, and so far, the prior art does not relate to the present invention. invention related technology
