The driving power of LED lighting fixtures is inseparable from the driving power supply, so what is the classification of the driving power supply of LED lighting fixtures? BETTER will answer it for you.

At present, the driving power of LED lighting lamps is mainly divided into two categories: constant voltage drive and constant current drive. At present, the constant current power driver occupies the mainstream. Let's look at the differences and characteristics of the two:

LED constant current drive

1. At present, the constant current drive LED power supply is the mainstream LED drive power supply in the market, but its price is relatively high.

2. the circuit output of constant current drive power is constant current. The output voltage varies with the load. The smaller the load resistance, the lower the output voltage. On the contrary, the larger the resistance, the higher the voltage.

3. Because the output current is fixed, this limits the number of LED lights used.

4. Contrary to the constant voltage drive, the constant current circuit is not afraid of short circuit of the load, but it is not allowed to open the load completely.

LED constant voltage drive

1. Because its voltage is fixed, when the parameters in its circuit are determined, the output current will change with the load.

2. the brightness will change due to changes in voltage

3. Driving LEDs with a constant voltage requires adding a suitable resistor to each string of LEDs to ensure uniform LED display brightness.

4. the voltage regulator circuit allows the load to be open-circuited, and prohibits the load from being completely short-circuited.

The above are the characteristics and differences of the two major types of LED power drivers for LED lighting fixtures. Knowing their characteristics, everyone should have some insights when choosing a power drive. If you are afraid of encountering problems when purchasing LED lighting fixtures, please choose an LED lighting manufacturer with a guaranteed brand quality.
