Technical Field

Background
LED lamps made of LEDs are called the most commonly used lighting lamps with the advantages of good quality, durability, energy saving, etc. However, the LED lamp has a disadvantage that the lighting effect of the LED lamp is greatly affected by the junction temperature of the LED, and the higher junction temperature of the chip will cause the lighting effect to be significantly reduced, and will affect the service life of the LED lamp. Because the LED lamp is when luminous, its self temperature can constantly rise, in the illumination work that lasts, if the heat that the LED lamp produced can not in time disperse away, will cause the damage of LED lamp, influence the life of LED lamp. Therefore, solving the heat dissipation problem of the LED lamp is very important to improve the performance of the LED lamp.
In order to solve the problems, some LED lamps generally directly transfer heat energy generated by the LED during lighting to an aluminum alloy or various metal shells for heat dissipation, or transfer heat energy by a heat-conducting silica gel, thereby reducing high temperature generated during LED lighting, reducing light attenuation of the LED, and prolonging the service life of the LED lighting.
To ensure an extended life and desired luminous output of the solid state lighting device, LED light fixtures are typically mounted or otherwise thermally connected to a heat sink that absorbs heat generated by the solid state lighting device and transfers the heat to its surroundings. To this end, such heat sinks typically have a large surface area, which is typically provided by a plurality of fins of a thermally conductive material (e.g., a metal, metal alloy, or thermoplastic) to ensure high rates of heat transfer between the heat sink and its surroundings. In this manner, the heatsink may effectively maintain the operating temperature of the solid state lighting device below a critical temperature at or above which the solid state lighting device may exhibit reduced lifetime and/or degradation of optical performance.
However, the general radiator is formed by simply arranging aluminum sheets, the aluminum sheets are arranged in different manners, the radiating effect is different, and the common aluminum sheet arrangement manner cannot effectively radiate heat. The common aluminum material is pressed and integrally manufactured by metal, which causes great limitation to the heat dissipation efficiency of the heat dissipation area.
