A LED lighting system in the modern theater and the corresponding control program is introduced. Studies show that
moderate and mutative brightness in the space would attract audiences' attention on the screen easily. SCM controls
LED dynamically by outputting PWM pulse in different duty cycle. That cinema dome lights' intensity can vary with
the plot changed, make people get a better view of experience. This article expounds the architecture of hardware
system in the schedule and the control flow of the host of the solution. Besides, it introduces the design of software
as well. At last, the system which is proved energy-saving, reliable, good visual effect and having using value by
means of producing a small-scale model, which reproduce the whole system and achieves the desired result.
