How to make a good led dimming power supply

There are two power supply methods for power supply, namely constant current and constant voltage. It is mainly to change the current or voltage to control the brightness of the lighting lamps. Moreover, this equipment adjusts the current supplied to the LED light-emitting tube, and finally achieves the purpose of adjusting the brightness. In fact, LED has very strict standards for supply voltage ...

What is the difference between DMX and DALI driver?

DMX or Digital Multiplexing is a fast speed control system, while DALI or Digital Addressable Lighting Interface is a slow speed control system. A dmx driver can have up to 512 connections while in DALI power supply system max connections are 64 only. In the DMX system, automatic addressing cannot be performed while in a DALI system automatic addressing is possible. Following are the basic working...

Is the on/off switch connected to the input or output side of the power supply?

It's okay to put both side of power supply. But it's better to put it on input side, In this case, as soon as the switch is turned off, equivalent to entire circuit is powered outage. If you put the on/off switch on the output side, although the switch is powered off, the led drive power supply is still working on standby with the lowest loss, and the power supply is under working states, one of t...

What is stroboscopic of LEDs?

Stroboscope is the constant fluctuation of light during the switching cycle. It's a flicker that occurs because of the frequency. A stroboscope is a light source that blinks quickly and repeatedly over time. Popular speaking, is the feeling of light beating, unstable, this phenomenon is the so-called stroboscopic. Almost all types of lights are prone to flicker, including incandescent bulbs, halog...

Introduction to the principle of 0-10V dimming power supply

The power supply design has a control chip. When the 0-10V dimming power supply is connected, the output current of the power supply is changed through the 0-10V voltage change, and the light is reduced. For example: when the 0-10V dimming power supply is modulated to 0V, the current drops to When it reaches 0, the brightness of the light is also off. When the 0-10V dimming power supply is adjuste...
