LED Dimming has been a common lighting requirement in Today's Professional LED Lighting / Interior Design. But for many, who are in LED Lighting Design / Interior Design / M&E Consultant, they might have found different Reliability and Performance problems when using Traditional Incandescent Dimmers (a.k.a, TRIAC Dimmers) to realize LED Dimming. There are already many websites saying that LED Dimming requires a new type of Dimmer. It's our intention to create our Application Video Library to explore different LED Dimming topics so that the relevant parties would be able to visualize it than simply reading another technical article online.
To provide a simple-to-use and cost-effective LED Dimming solution for customers’ transition to Professional LED Lighting effect, our 450W / 220 - 240Vac Digital Phase Cut LED Wall Dimmers are designed for LED Deep Dimming. Not only are backward compatible to single Live-wire operation for TRIAC Dimmer Replacement, our LED dimmers have Other Benefits from Digital Processing, which upgrades Single Pole Dimmers with new features matching with today’s market needs.
Gen 3 LED Phase Dimmer
With our past effort, our Gen 3 LED Dimmer, DZ3G450DIAL, is officially listed on the leading Professional LED Lighting Manufacturer, SORAA®’s Compatibility List for its Professional LED Lamps. Not only that, our different solutions have been using in multiple projects by some prestigious customers, who encountered LED Dimming problems for their Interior Design projects. By working with LED Driver and Lighting Fixture Suppliers, Designers and Electricians, even Retailers, we've gained a comprehensive end-to-end understanding of the overall LED Dimming / Professional LED Lighting applications. This extensive Marketing experience also fuels our continuous product innovation for LED Dimming applications!

Dimming Range Customization with TCI DC MINIJOLLY 1-10V LED Driver & Further Discussion on 0/1-10VThis video starts off to demonstrate how to use the Min-Trim option of the DZ1G1TEN to set the Dimming Range of a Lighting Fixtures that is driven by a 1-10V Dimmable LED Driver. By using the Min-Trim option to set the Lowest Light Output between 0.8V - 3.5V, the result is to have the overall lighting range mapped from the Maximum (10V) to the New Minimum Voltage level: The lower the Minimum Level, the wider the dimming range.
We then continue to show that if we continue to adjust the Min-Trim downward, we are able to use the DZ1G1TEN to control the TCI driver (DC MINIJOLLY model # 122400) so that it switches off the light (Dim-to-Off feature). However, we also point out that for the < 1V control voltage range, such kind of behavior is not always guaranteed and is highly subject to the individual driver manufacturers' own interpretation of what "Minimum Light Output" means. This, in turn, explains the inconsistency of many 0-10V dimming devices as experienced in the market.
Furthermore, from the power meter measurement, we highlighted that although there is no light output from the driver (Dim-to-Off), the driver continues to operate and is still consuming a certain amount of power. The appearance of switching off the light by the dimmer should not be mistaken as actually cutting off the AC power to the driver (or switching off the driver).
In fact, feeding 0V to the control port is essentially the same as shorting the DIM+/- terminals, which is not recommended for prolonged operation. Hence, our suggestion is to keep the minimal light output as a way to remind of proper AC power-off mechanism to the LED driver instead. Thus, in 0/1-10V applications, we are always reminded of using a separate On/Off switch or a Power Management Unit to cut-off the AC power to the LED Driver.
Note that the TCI DC MINIJOLLY LED Driver # 122400 can be configured as either a Constant Current and Constant Voltage LED driver. Although we only showed the Constant Current mode in this video, we can also achieve same performance when the driver is configured as a Constant Voltage mode (typically for low power LED strip connection).
