The Wireless Controlled LED Based On Single-chip Computer

LED(light Emitting Diode)light source is widely used in various lighting occasions with its high brightness and low energy consumption characteristics.With the rapid development of LED technology in recent years,the features of emerging lighting products are constantly perfected.With the continuous development of society,the easy lighting function can not meet the needs of people's lighting.Especially in the home aspect,traditional lamps gradually withdraw from the illumination market,while intelligent lighting becomes the direction of development.This paper aims to design an LED illumination system which can be controlled by mobile APPP.On the basis of summarizing the predecessors led and taking full account of people's illumination demand,the system adopts SCM as the main control unit,handles the information of each module and makes the corresponding control;system lamp Group contains R(red),g(green),B(blue)three kinds of LEDs,Using the tri-color color matching principle of Chroma,using PWM(pulse width Modulation)technology to modulate three kinds of LEDs,we can realize the dimming and tinting of the whole led system.The system can realize the adjustment of brightness 0%?100%and full color adjustment to satisfy people's diversified illumination needs,and the wireless remote control of led by infrared technology can be realized by mobile APP,which makes the lighting system more convenient and intelligent.This article mainly introduces the hardware circuit construction of the illumination system and the software program,and the system is designed in the principle of high efficiency and economy.The diversified function of the system can effectively improve the single phenomenon of lighting function nowadays,which has a wide application foreground and market foreground in the development of science and technology and the improvement of home intellectualization.
