Heat dissipation structure of LED lamps

The present invention is a heat dissipation structure, in particular, a heat dissipation structure for an LED lamp, which can increase the heat dissipation area and improve the effects of heat radiation, heat convection and heat conduction.

With the evolution of technology, Light Emitting Diode (LED) has become a trend leading the lighting field due to its low energy consumption, long life, small size, no pollution and good luminous effect. However, as the power of the LED increases, the heat generated by the LED cannot be effectively dissipated, resulting in a decrease in luminous efficacy. Although the overall heat generation of the LED is not high, it is far more than other light sources when converted into heat flux per unit volume. Therefore, when the LED cannot be effectively dissipated, the LED luminous efficiency is easily reduced and damaged.

That is to say, if the temperature is increased, if the heat is not effectively dissipated, the junction temperature of the LED wafer p-n will increase, thereby reducing the photon energy emitted by the wafer, resulting in a decrease in light extraction efficiency. At the same time, due to the increase in temperature, the spectrum emitted by the wafer is red-shifted, and the color temperature quality of the LED is lowered.

At the same time, when the temperature of the p-n junction of the LED is increased, the luminance of the LED is inversely proportional to the linear relationship, and for the service life of the LED, the exponential relationship is rapidly shortened. For now, the most common method is to set the heat sink fins on the lighting device to Improve heat dissipation by means of thermal convection.
