摘　　要：为了解决传统镝灯类影视灯具色温不可调和发光效率低等问题,设计可变色温的大功率摄影灯,主要由LED光源模组、智能控制模块、LED驱动模块和灯具支架组成。LED光源模组包括大功率CSP-LED光源和与之配套的散热器等,智能控制模块则采用Wi-Fi、蓝牙和DMX512三种控制方式结合的形式,整个灯具依据程序指令对影视灯具的参数诸如色温、亮度等进行调节,实现影视灯具的智能化工作。In order to solve the problems of the traditional dysprosium lamp,such as low luminescence efficiency and irreconcilable color temperature,a high-power photography lamp with variable color temperature is designed,which is mainly composed of LED light source module,intelligent control module,LED driver module and lamp bracket.LED light source module includes high-power CSP-LED light source and its matching radiator,etc.The intelligent control module adopts the combination of Wi-Fi,Bluetooth and DMX512 control modes.The whole lamp adjusts the parameters,such as color temperature,brightness,etc.according to the program instructions to realize the intelligent work of the film and television lamps.
