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.
Implement Dimming Function to a LED Lamp with a Multi-Power LED DriverLong product lifespan is a big part of the LED lighting value proposition. In order for the proposition to hold, the quality of the LED driver is a critical factor to consider. However, it's not uncommon to find an LED driver that fails to operate after a year or two. Often, after replacing the LED driver, an LED lamp will function as new again. But since most LED drivers have constant current output, sometimes it's not straightforward to find the right replacement driver with the right output voltage and output current. This is when a Multi-Power LED Driver comes in handy. In this video, we'll use a multi-power LED driver from our business partner, IDP Power Technology Ltd. and our DZ1G1TEN, 1-10V Controller, to modify a malfunction LED lamp to a dimmable lamp. Whether it's a Dimmable E27 and GX53 bulb from IKEA (dimmed by our Phase Dimmers) or a lighting fixture that requires an external LED driver and dimmed by our 1-10V controller, it's our intention to show that LED dimming can be very straightforward with the appropriate equipment in place!
[Above] Model #: SC-AD-025W-0A90-A-AV-20 has output voltage from 5V - 60V and the output current from 150mA - 900mA, in step of 50mA that can be set with a 4- bit DIP switch; these type of LED drivers are also known as Selectable-Output Constant Current LED drivers; note the LED driver also has a 1-10V control interface for connection with DZ1G1TEN. In this video, we'll also show how to control the dimming range with the Minimum-Trim option of DZ1G1TEN and a trick to further adjust the brightness with different output current levels for replacement projects. We point out that the most frequent pitfall for 1-10V connection is that DIM+ and DIM- mixed up with the LED driver inputs, which would result in no dimming function. Note for 1-10V control, the positive and negative terminals are not interchangeable and must be connected correctly.
