Trailing edge led dimming driver

Trailing edge dimmers are now the more popular of the two types. Trailing edge dimmers are more sophisticated than leading edge dimmers, and usually use a mosfet metal oxide semiconductor field effect transistor or igbt insulated gate bipolar transistor switch rather than a triac and coil. Trailing edge dimmer function in led drivers erp power. Generally, when the driver that the luminaries include is trailing from the elt brand. Traditionally, this kind of technology is used with electronic drivers or transformers. With an incandescent light bulb, domestic dimmers promote a resistance that is characterized as ideal by many. Trailing edge dimming for led bulbs wholesale led lights. An elv dimmable led driver is also known as a trailing edge dimmer. Compatible with the most common leadingedge and trailingedge phase dimmers. There are no additional wires on a phase dimming driver.

Everything there is to know about the trailing edge dimming for led bulbs. Constant voltage dimmable led driver trailing edge dimmer led. Description trailing edge elv dimmable protocol led drive with 10% dimming remote mounting distance up to 10 20awg, 15 18awg to led load led load. There is a massive installed base of phase dimmers which is why they are so popular. When trailing edge dimmers are paired with a compatible led driver the resulting dimming capabilities are beyond impressive. Use our free driver selector tool to find your specific led driver.

What are the different types of dimming for led drivers. Selecting the best led driver for dimming led strip. If you want to dim your led driver from a leading edge triac dimmer, or trailing edge dimmer you will need to select a led driver from the power source pdv series. Different dimming types for led lighting arrantlight blog. How to choose leading edge dimmer or trailing edge dimmers. Dimming by cutoff in the wave on its descending side, from the end cutting backwards phase cutoff at switch off. Dimming leds the difference between leading and trailing. There are certainly advantages and disadvantages to a leading edge dimmer, and the same can be said about trailing edge dimmers. Particularly beneficial for incandescent and halogen bulbs is the soft start feature in trailingedge dimmers, which prevents filament bulbs from dying or exploding of thermal shock when first switched on. Dimmable constant voltage led driver with trailing edge.

Hatch led drivers with a p in the part number after the current. They have several advantages over leading edge dimmers including smoother control, soft start and silent running when in operation. The electrical current sinusoidal signal is turned off at the end of the ac input waveform immediately before the zero crossing traditionally used for electronic drivers or low voltage transformers capacitive loads. Browse through our range of dimmable drivers as well our low voltage dimmable. The dimmer switch must be led compatible from 04w 100200. Both types of dimmer can work with dimmable leds however due to its advantages, trailing edge is the preferred and as such led manufacturers have designed their retrofit lamps to work best with this type. Unlike incandescent bulbs, which are all dimmable by default, led retrofit bulbs have a builtin driver in their base.
