Abstract

The invention relates to the electronic technology field and discloses a voltage power supply used for driving a light emitting diode lamp. The voltage power supply comprises a shell (1), an LED lamp (2), a control button (3), a current sensor and an integrated circuit board, wherein the LED lamp (2) and the control button (3) are arranged on the shell (1); and the current sensor and the integrated circuit board are arranged in the shell (1). The integrated circuit board is provided with an AD conversion circuit, a control switch circuit and a single-chip microcomputer. The control switch circuit is connected in series in a power supply output loop and is used for controlling conduction and disconnection of an output circuit. In the invention, the power supply and load equipment can be well protected, equipment losses are reduced, a service life is prolonged, and simultaneously accidents of a fire hazard and the like are avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a voltage power supply for driving light-emitting diode lamps. Background technique [0002] LED lamps cannot directly use conventional mains grid voltage. Due to the characteristics of the diode light source, in order to meet the special voltage and current requirements of the diode lamp, a specially designed voltage conversion device must be used to make the diode lamp work normally. So the diode lamps have a power drive mode different from traditional lamps. There are two types of driving methods for diode lighting power supplies: first, constant current driving power; second, regulated voltage driving power. Regulated drive power supply, when the parameters in the stabilized circuit are determined, the output voltage is fixed, but the output current changes with the increase or decrease of the load, so it is particularly important to monitor the current first, and the c...
