Rated power so it can be compatible with the following LED lights. The problem for the no-load losses can be used to detect whether a load access MCU,[link widoczny dla zalogowanych], LED access when not detected, you can turn off the circuit after the class BUCK,[link widoczny dla zalogowanych], reducing the load loss. Finally, the SCR compatibility issues. Constant power control scheme, using pure hardware mode to stabilize the SCR turns on, the adaptability of dimmer or limited.
Constant current control in the MCU program,[link widoczny dla zalogowanych], in addition to stable hardware circuit, as well as software to SCR chopper waveform after the identification processing. Can be set by software to determine the waveform after the chopper is really distortion or dimming, and to determine whether or not to alter the dimming signal.
Therefore, constant current MCU control program improves the adaptability of dimmer. Of course, the MCU current control scheme with two closed-loop control, as opposed to single-level ASIC's constant power control scheme, there are some shortcomings,[link widoczny dla zalogowanych], starting with the structure of complicated than the constant power control scheme, a slightly higher cost ~ 2RMB, the other is more efficient than constant power scheme must be low, but can meet the "Energy Star" requirements.
