Frequently asked questions about the use of LED power supplies

Heat dissipation problem

The LED is a cold light source, and 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 problems

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 problem

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 and so on. Analog driving refers to analog circuit driving, including AC constant current switching power supply, DC constant current control circuit.

The common problems in the use of LED power supply are mainly the above three points. In addition, LED lamps are not developed for a long time, and there are not many experiences that can be learned. 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 gives the LEDs a large heat dissipation space, and the heat dissipation space for the power supply is small.
