Abstract

The invention discloses an LED brightness setting method and an LED powers supply. The LED power supply comprises a power carrier demodulation unit, a control unit, a storage unit and a power unit, wherein an input end of the power carrier demodulation unit is connected with a power line, an output end of the power carrier demodulation unit is connected with the control unit, the control unit is also connected with the storage unit and the power unit, the power carrier demodulation unit is used for receiving and demodulating a power signal transferred through the power line so as to acquire a current setting signal, and the control unit is used for changing a preset current value stored in the storage unit according to the current setting signal and controlling the power unit to drive an LED to emit light according to the changed preset current value. In the LED power supply, the brightness adjustment of the LED is achieved by changing the preset current value, so that an adjustment hole is not needed to be formed in a shell of the LED power supply, glue filling is facilitated, and sealing and water prevention are achieved; and meanwhile, the brightness adjustment range of the LED is also expanded, so that the LED power supply can be applied to more types of LEDs.

Description

technical field [0001] The invention relates to the technical field of power circuits, in particular to an LED brightness setting method and an LED power supply. Background technique [0002] In LED applications, the sensitivity of LEDs to current determines that different LEDs have different current requirements, but for a single type of LED power supply, the maximum current is a fixed value, which will cause different LEDs to be equipped with different This will bring difficulties to LED power supply manufacturers. There may be thousands of types of LED power supplies that need to be designed and produced, which will increase management costs and easily cause mixed use. In fact, the difference of most LED power supplies is only the slight difference in current, and other materials are the same. Therefore, in order to save costs, LED manufacturers generally use the same design model in the same power segment, and change the power supply through some adjustment methods. The...
