Description
Technical Field

Background
The existing silicon controlled intelligent dimmers on the market generally have the problems that the brightness change among all dimming gears is not uniform, and the minimum brightness is not matched with the starting voltage thresholds of different load bulbs, for example, if a certain dimmer uniformly divides the delay time into 7 gears from the minimum value to the maximum value, the visual difference of the change of the low gear is very obvious, and the change of the high gear is hardly perceived. Designing the lowest-level brightness of the dimmer to be a proper value may make it difficult to take into account different loads such as incandescent lamps and LED lamps. Taking an AC frequency of 60Hz as an example (phase cut period = 1/(60 × 2) =8333 us), the incandescent lamp can start to have an illumination effect when the DelayTime is less than 6000us, and most of the LED lamps are already very bright at this time, if the DelayTime is added to more than 7000us to take care of the performance of the LED lamp, the incandescent lamp can only make the filament just turn red at this time, so that the visible light dimmer cannot give consideration to various loads, and meanwhile, the gear cannot be intelligently adjusted, so that the user experience is poor.
