As an advanced application of LED light, LED stage light enjoys their unique superior per-formances of long life and fast independent color adjustment which are widely used in stage lighting.In order to continuously improve the product performance and reliability of LED stage lights, 32-bit embed-ded STM32F103 chip is used instead of the original 3-chip of 8-bit micro-controllers, greatly simplifying the circuit and procedure and significantly increasing the software performance.The researchers optimize and experiment the whole system′s circuit, the motion control way, the dimming way and the temperature protection to let the lamps have the better control performance, function and reliability, and to improve the motion control accuracy, stability and the approximately stepless four-color light dimmer.The princi-ple we develop has been applied to many head-moving lights which proves very effective.
