Comprehensive reason is mainly that only twenty percent of the electricity is used for light itself, while the remaining eighty percent of the electrical energy is used to produce heat. If the heat it produces can not be timely given off, it will cause the wafer temperature too high. The main reason for reducing the service life of the LED is that it can39。t realize LED energy saving effect , So my design is using semiconductor refrigeration piece refrigeration technology to realize LED heat by LED single chip microputer as the control core. Meanwhile, in order to verify the feasibility of the design, I joined the NOKIA5110 LCD as the display module. The temperature of DS18B20 temperature sensor on the LED lamp was monitored in real time, and I joined the buzzer as a warning to remind what time the temperature is too high. So the semiconductor refrigeration piece should begin to work. Finally, because of the semiconductor refrigeration piece of thermocouple function, it will affect the cooling effect of it that its generated heat is not timely given off. So I joined the fans for cooling the semiconductor refrigeration piece. Although the design increases more devices than traditional LED lamps, pared to the energy efficiency of LED, it has very practical significance. Keywords: LED。 single chip。 semiconductor refrigeration piece。 5110 LCD screen。 DS18B20 temperature sensor
