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.

Adding Control Intelligence to a Phase Dimming System

As the LED lighting industry continues to advance with better lighting product performance, the demand for more control intelligence has also raised proportionally. In between only On/Off and Smart Control with a mobile phone, in this video, we utilize only a Timer, a Motion Sensor, and a Dimmer (& LED Driver) unit to realize some level of control intelligence. This proposed system makes phase dimming more interesting by adding control intelligence to further contribute to energy saving. Unlike a centralized control system, this system can be added to wherever it is needed at low costs.

In this video, we stimulate a typical energy saving scenario, where the lights are dimmed and switched-on fully according to the body motions detected. The idea is similar to a T8 tube with an integrated sensor in the facilities management or building staircases. But unlike a sensor integrated T8 tube, this proposed system can be adapted to other phase dimmable lighting fixtures at will. In this video, we’ve used a CCT changeable and a regular phase dimmable downlight and dimmable LED light bulbs to illustrate the idea.

Furthermore, the timer, sensor, and dimmer units can be located separately that allow the units to be placed at more convenient locations. As the wiring is very simple and only requires live-and-neutral wires for connection,  this proposed system is good for installation, where an only small budget is available and implementation is only required for few selected locations. Potential applications would include Commercial Lighting and Art Museum Lighting etc.

As different combinations of the control units can achieve different control intelligence, this proposed solution only serves as a proof-of-concept for lighting designer and electrical contractors to consider and brainstorm for applications that require easy implementation of more intelligent control of the lighting effects.
