What is the connection way between LED and LED drive power matching
06 May, 2021
We already know very clearly that there are only two ways to drive the LED: Constant current type: the current does not change and the voltage changes within a certain range (varies with the load) Constant voltage: constant voltage and current changes within a certain range (varies with load) There are three ways to cooperate with LED lights: series and parallel. In Series: The LED driver i...

Working principle of 0 10v dimmable led driver
10 May, 2021
From the previous ordinary fluorescent lamps, electronic ballasts that used 0-10V to adjust the signal, to the current LED, it can be said that it has been widely used in Europe and the United States. Street lights use 0-10V as the dimming signal, and use the computer to automatically adjust. In the wee hours of the morning, when the usage is low, the brightness is automatically adjusted, and the ...

What are the characteristics of the DMX512 protocol optical control card?
13 Sep, 2023
The DMX512 protocol was first developed by the USITT (American Theater Technology Association) to control the dimmer from the console with a standard digital interface. DMX512 surpasses the analog system,but it cannot completely replace the analog system. The simplicity, reliability and flexibility of DMX512 make it quickly become the protocol of choice when funds permit. In additio...
