[0020] LED lamps have lower energy consumption, longer life and lower heat generation compared to traditional fluorescent lamps and incandescent lamps. Installing sensors and timers in intelligent LED lighting fixtures can achieve automatic switching and brightness adjustment, thereby saving energy. The heat dissipation of LED lamps is very important because high temperature can affect the life and energy consumption of LEDs.
