Besides energy saving, controllability is the next highly expected feature of LED Lighting over Traditional Lighting. However, such a control aspect seems to be missing in daily applications. Since 2015, we've been developing & marketing Phase Dimmers* and related products to address LED dimming control

Driven by our project field experience, we developed a new type of Tunable White control using Phase Dimming & 0-10V technologies, which gives our Tunable White Controller (DZ1G300TUNE) & Dynamic Lighting Controllers (DZ2G300TUNE_TOGG / _PUSH). It's our goal to lower the technical and costs barriers for different Circadian Lighting or Commercial applications that desire Multi-Purpose Lighting.

* Our 450W / 220-240Vac Single Live-wire Operational Trailing-edge LED Phase Dimmers released to market includes DZ2G450DIAL & DZ1G450CAPS (2015), DZ3G450DIAL (2017), DZ4G450MULT (2018). In 2017, our DZ3G450DIAL was listed as a SORAA® Compatible dimmer. In Q2 2021, an Enhanced version of DZ3G450DIAL has been available.

In this Application Video Library, we shared a number of interesting topics on LED dimming or how our products can be applied in different scenarios.

Minimum-Level-Set with Philips Tunable White Recessed Spot Light (61034/31/66) to prevent LED Flickering

As there is not yet an established market standard on LED dimming, any products with adjustable brightness level can be called “dimmable” products. The dimming performance of LED Driver is the first condition for dimming performance, i.e. if a driver is not dimmable, the dimming performance is going to be problematic.

How deep does the dimmable LED driver support dimming is another key for overall Deep Dimming effect. Since there are many LED drivers with varied quality, our Minimum-Level-Set feature allows the dimmer to match the optimal dimming level of a LED dimming system. By manually setting a “System-Minimum”, Legend Tech DIMEZE™ dimmer forbids further dimming below the minimum brightness level and hence, prevents flickering. The option to SET and RESET the Minimum-Dimming-Level is straight-forward as shown in this video.
