50W 2CH 0-10V LED DriverHere is the text version：Hello, everyone. I'm Jiaqi Chen from MOONS' Japan. Today I would like to introduce a 50W 2CH 0-10V LED driver.Here are the main features of the driver. The driver owns two outputs channel and four dimming modes. They are Tunable white, dim to warm, solo, and dual. The LED driver's dimming range is 0.1% - 100%, and the dimmer curve can be switched between logarithm and linear.These are the shapes of the LED drivers. The left one is built-in version BQI211, and the right one is independent version BQI251.Next, let me introduce the dimming modes of the driver.The first dimming mode is tunable white. The Left is the LED driver, the right is the luminaire which has warm and cold colors, and the middle is a two-channel 0-10V dimmer; the left channel is used to adjust brightness, while the right channel is used to adjust color temperature. Thus, this is the tunable white whose brightness and color temperature can be adjusted.The second dimming mode is dim to warm. One channel can be used to control both brightness and color temperature simultaneously. The luminaire remains a 2CH luminaire with color temperature. Blue dimmer is a Lutron 0-10V dimmer. A remote dimmer is shown in black. At low brightness, the color is close to the fire, but when brightness is increased, the color becomes cool white. Using one channel of 0-10V to control the color and brightness, this is Dim to Warm.The third dimming mode is the solo mode. When two separate LED modules are powered, the dimming effect is synchronous. There is only one 0-10V dimming signal required for this mode. As I just mentioned, this is a wireless dimming system developed by Lutron. This is a 0-10V single-channel slide dimmer, so it can adjust brightness and color temperature simultaneously same as the wireless dimmer.The last dimming mode is the dual mode. This power can also be applied to two separate LED modules. But the dimming effect is separate, one signal control channel 1, and another signal control channel 2.This is the general introduction to our LED driver. These two are luminaires with the same color temperature. This is a two-color luminaire. This one is the LED driver. And this is a 0-10V dimmer with a remote dimmer.I'll show you how to dim it later. Now let me do a dimming demonstration.What I am demonstrating now is a Dim to Warm connection method, which is to use a signal to control the change of color temperature and brightness simultaneously. When the brightness is at the minimum of 0.1%, the color temperature is also the lowest. For example, the warmest effect of color temperature is 2700K, when dimmed to 0.1%, the color temperature of the light would be 2700K. This is the lowest color temperature, and as the brightness goes up, the color temperature will change slowly.We can set a specific value for the LED driver. When the brightness reaches this level, the color temperature becomes cold. I will introduce the details later. The color temperature gradually turns white as it rises until it reaches its brightest point. Your power will determine the brightness of the display. The current light is now set to 350mA. It is a very soft dimming. Likewise, the lower the brightness, the warmer the color temperature. In this case, the light is dim to warm.As you can see, the dimming performance is very impressive. A signal can be used to control its brightness and color temperature simultaneously.This was a popular dimming method before. If you have this kind of luminary, you can try them. Here I'll introduce the level value of dim to warm which I just mentioned.Now, as you see this is the setting interface on Dim to Warm, this is the color temperature lamp.You can adjust the value according to the type of lamp you have. What number would be the best and most comfortable depends upon the lamps and your personal preferences.We can set the value more conveniently through this software. I'm going to set it to 1, which I think is ideal. You also can set the value to 2,3,5 or 10 according to your adjustment. For other values, you can also have some changes, the same as the color temperature settings.According to the color temperature lamp's color temperature, we can change physical and logical color temperature values in the software. For example, change to 1500~3200 or 2700~5000.There is another parameter, you can change the dimming curve to be logarithm or linear. There are four dimming modes, tunable white, dim to warm, solo, and dual. Our LED driver has some different dimming modes and curves.Today's presentation is mainly about this 0-10V LED driver. So, if you need to use 0-10V dimming, you can try to use this LED driver to do a test and see if it meets your needs.
