How to select a correct triac dimmer for LED applications?
Leading edge dimmers are typically used only on leading edge dimmable led driver and trailing edge dimmers are typically used only on trailing edge dimming power supplies. hence, Whether the leading or trailing edge dimmer can be adapted to a dimmable led driver, it depends on the power supply, not the dimmer. So, pls use trialing edge dimmer to a trailing edge dimmable driver and leading edge dimmer to a leading edge dimmable driver. If the LED driver you are using is able to work with both leading edge & trialing edge, then choose any one of them is suitable.
Forced to use the leading edge dimmer to adjust the power supply that can only use the trailing edge dimming may have flicker incompatibility problem, the worst incompatibility is the dimmer or dimmable driver would damage.
