• Energy variation logic control algorithm

In this study, a composite light emitting device for sunset emulator with a novel control algorithm is presented. The proper light sources corresponding to the sunrise or sunset light's wavelength and its integrated circuit are discussed. Sequence control adjustment is used to establish the lamp design, imitating the sunrise and sunset with time duration. The sunset-simulation mode uses light beam, which is generated by different light emitting elements, filtered by an optical filter; and many groups of the light emitting elements capable of irradiating red light and infrared light to simulate sunset spectrum with an energy variation logic control algorithm. By using different utilization modes, a better imitating effect can be achieved.
