When it comes to the compatibility of triac dimming, one of the common problems is that the maximum and minimum firing angles produced by the phase-cut dimmers are generally inconsistent during dimming, which results in the dimming performance of LED lamps. Differentiation.

Different brands and different product models have a very large range of trigger angles. As a result, their on-time and power applied to the load will also change.

The conduction period of the phase-cut dimmer is directly related to the working current of the LED, and therefore affects the luminous output of the lamp. Assuming that the triac LED driving power supply has a fixed dimming curve, the performance of the driving power circuit will be different for different triac dimmers. In addition, any non-linearity in the dimming curve will exacerbate the performance difference between dimmers.

In addition to compatibility issues, common problems with thyristor dimming include: when the dimmer or system is under low load, due to insufficient maintenance current, it is easy to be unstable and cause LED lights to flicker.

In combination with the above problems, Quanzhou Smarts professional dimming power supply manufacturer has designed different solutions for LED triac dimming power supplies for various triac dimmers and dimming systems on the market, hoping to solve them for our customers Dimming power matching compatibility problem!
