Abstract

The invention is applicable to the field of power supplies, in particular to a battery discharge circuit, a power supply and an LED lamp, the circuit comprises a constant-current drive control chip, an adjustable width pulse circuit and a battery discharge passage, wherein the constant-current drive control chip is used for outputting constant-current drive current; the adjustable width pulse circuit is series-connected between a positive end of a battery and a pin of the power supply of the constant-current drive control chip and used for changing the resistance of a charge-discharge resistor, outputting the adjustable width pulse and regulating the high-level duty cycle; and the battery discharge passage is series-connected between the positive end of the battery and a drive pin of the constant-current drive control chip and used for receiving the drive current outputted by the constant-current drive control chip. An oscillation working circuit in the battery discharge circuit is designed to the adjustable width pulse circuit, and the discharge time of the battery is prolonged by changing circuit parameters and adjusting the pulse width.

Description

technical field [0001] The invention belongs to the field of power supplies, and in particular relates to a battery discharge circuit, a power supply and an LED lamp. Background technique [0002] The current battery discharge circuit cannot adjust the pulse width because the pulse width ratio of the oscillating working circuit is fixed, so that the battery discharge time cannot be extended. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a battery discharge circuit, aiming at solving the problem that the pulse width ratio of the existing battery discharge circuit is fixed and it is difficult to prolong the battery discharge time. [0004] The embodiment of the present invention is achieved in this way, a battery discharge circuit, the circuit includes: [0005] Constant current drive control chip, used to output constant current drive current; [0006] The adjustable width pulse circuit is connected in series betw...
