Matters needing attention

According to the characteristics of power grid, led characteristics and related LED products, the following points should be considered when selecting the driving power supply for LED ceiling lamps: General principles

A, according to the characteristics of LED current and voltage, it is ideal to use constant current drive. The current fluctuation caused by the change of LED DC voltage can be avoided, and the constant current can stabilize the brightness of LED.

B, in addition, the LED luminous flux is inversely proportional to the temperature, so in use, it is necessary to minimize the power supply heating and carefully designed cooling system. Thereby reducing the working environment temperature of the LED.

C, in order to ensure the overall life of led products, the junction temperature of LED must be controlled within a certain range, that is, the working environment temperature of LED products should be well controlled.
