For those of you who have been in the LED lighting industry all the year round, you will definitely come into contact with various dimming power supplies. How to choose the right LED dimming power supply is especially important. Then follow the Xiaobian to find out.
First, select wired / wireless dimming according to demand
Before we choose the right LED dimming power supply, the first thing to be clear is: wireless or wired way to dim, the current LED mainstream dimming mode: wired dimming: thyristor dimming, 0/1-10V, DALI, PWM, DMX wireless dimming: Bluetooth, WIFI, Zigbee, Z-Wave
Second, the comparison of several wired dimming methods
Take led dimming power supply as an example, most of our products are wired dimming power products.
1. Development process of several dimming methods
SCR----0/1-10V driver----PWM drivers 100w----DALI----DMX
2, the advantages and disadvantages of several dimming methods
Led dimming power prompt: can be selected according to the budget cost and actual needs, if not very clear can communicate with the crown technicians, recommend the most cost-effective dimming method for you.
Third, how to choose constant current or constant voltage dimming power supply
If you do not know how to choose constant current or constant pressure, you can judge according to the parameters marked by the luminaire. If the output voltage is: DC12V/24V/36V, it is a constant voltage lamp. Common constant voltage lamps have: LED light bar, light strip, MR16 and so on. If the output current is constant, such as 350mA, the output voltage is a range value, such as 3-15V, which is a constant current luminaire. Common constant current lamps have: downlights, ceiling lights, panel lights, and the like. For example, the common 5050 monochrome/RGB light bar power is 14.4w/m, and the lamp power can be calculated according to the length of the lamp strip to select the constant voltage dimming power supply. The constant current luminaire can be equipped with a dimming power supply with appropriate power and current according to the output current and power.
The above is the content of the led dimming power supply for everyone to share, I hope to help everyone. If you have more information about LED dimming power needs to know, please contact us in time.
