What are the common problems with LED power supply in use? The application of LED power supply is more and more extensive, so what are the common problems in the use of LED power supply? Zhongfu photoelectric plant lamp power supply manufacturers have summarized some for you, interested friends to come to understand:

Frequently Asked Questions about LED Power Sources

1. Thermal issues

The LED is a cold light source, the operating junction temperature cannot exceed the limit, and a certain margin must be left when drawing. The whole luminaire should be considered in a beautiful shape, convenient installation, light distribution, heat dissipation and many other problems. It is necessary to find a balance among many elements, so that all the lamps are the best.

2. Using parameter issues

The selection of purchased power sources mainly depends on the voltage scale of constant current and constant current. The constant current value is chosen to be the standard current of the LED. The selection of the voltage scale should be moderate, try not to choose a larger scale to prevent the dross of power.

3. LED life issues

The LED drivers we refer to include digital drivers and analog drivers. Digital drivers refer to digital circuit drivers, including digital dimming control, RGB full color change. Analog driving refers to analog circuit driving, including AC constant current switching power supply, DC constant current control circuit.

Frequently Asked Questions about LED Power Supply There are three main points. In addition, LED lamps are not developed for a long time, and there are not many experiences to learn. Many of them are constantly improved. Some LED luminaire manufacturers use the power supply for the outsourcing or outsourcing. The luminaire painter knows little about the power supply, and the heat dissipation space for the LED is large, and the heat dissipation space for the power supply is small.
