Design of LED Driver Controller Based on WiFi Dimming

设计一种基于WiFi短距离无线数字通信技术控制LED光源亮度的驱动控制器。采用PWM控制LED光源亮度,用脉宽调制技术精确控制流过LED光源的电流,为LED光源提供恒定的驱动电流和安全稳定的负载。使用者可以通过手机控制软件设置四路LED光源的亮度、色温等光学参数,也可以根据相应的应用场合设置光照时间以及光照模式等。实验证明,该控制方法简易、可靠、方便,具有一定的实用意义。

This paper designs a LED driver controller based on WiFi short-range radio communication technology to control the brightness of LED light source.Using PWM to control the brightness of the LED light source,pulse width modulation technology is used to precisely control the current flowing through the LED light source to provide a constant drive current and a safe and stable load for the LED light source.The user can set the optical parameters such as the brightness and color temperature of the four-way LED light source through the mobile phone control software,and also set the lighting time and lighting mode according to the corresponding application.Experiments show that the control method is simple,reliable,convenient and has certain practical significance.
