Research and Implementation of the Portable LED Stage Lighting Control System

With the development of stage lighting technology, people have increasing demands for the lighting control, such as real-time and portable, However, existing LED dimming control equipments usually have large size and complicated functions, so they are not easy to move and operate. In order to improve these problems, this paper proposes a portable LED stage lighting control system and designed its software and hardware. Its hardware is composed of three parts: stage lighting manipulator, the communication lines based on DMX512 protocol and LED dimming control circuit. ATmega16 is the core of the control system. Data transmission follows the DMX512 protocol. The test results showed this system had stable performance and high reliability, which can completely met the requirement of stage lighting control. Its simple structure and convenient operation made it easy to carry and use. Meanwhile, using LED lamps instead of traditional ones can effectively save energy.
