Abstract
Aiming at the needs of different lighting applications, combined with the characteristics of LED dimming and color control, and using MSP430 digital control technology, a novel LED intelligent dimming and color control system was designed. The system integrated Bluetooth remote, human infrared sensor, voice/gesture control and other control modes, which could achieve LED multi-mode dimming and color intelligent control. System hardware and software were designed to develop a prototype to experimental verification. The designed method proposes new ideas and information for LED control.
Highlights
With the development of communication networks, electronic information, LED lighting and other technologies, and the constant improvement of people’s living standards and the concept of green lighting, intelligent lighting has to get promotion
The designed system can use APP software and Bluetooth technology to control LED light switches, color and brightness, including the Bluetooth control mode, in order to control the modes of diversification and personalization
As can be seen from the test results, the system can be controlled according to the designed control mode, which achieve the prediction design goals and control effect
Summary
With the development of communication networks, electronic information, LED lighting and other technologies, and the constant improvement of people’s living standards and the concept of green lighting, intelligent lighting has to get promotion. The designed system can use APP software and Bluetooth technology to control LED light switches, color and brightness, including the Bluetooth control mode, in order to control the modes of diversification and personalization. The main control modes include: gesture control, human infrared sensor control, automatic light intensity control and Bluetooth remote control. The gesture control using ultrasonic ranging sensors to achieve, through gestures of far proximity sensors adjust the brightness of the light; human infrared sensor can detect whether the person to achieve different color conversion control; automatic light intensity control for the controller detects ambient illumination intensity, LED lighting dimming control; Bluetooth remote control, combined with intelligent mobile terminal software to achieve the LED lighting switch / dimming color control
