Description

technical field [0001] The invention is a power supply for LED lamps with timing power reduction, which belongs to the field of LED lamp power supply equipment. Background technique [0002] LED power supply is a kind of power supply. It is a device that provides power to electronic equipment, also known as a power supply. It is deployed as a different power input on the device connected to an independent circuit device with two or three power inputs. Dry batteries, etc. are also called power supplies; devices that convert alternating current into direct current through transformers and rectifiers are called rectified power supplies. [0003] In the prior art, there is no short-circuit protection mechanism installed in the traditional traditional LED lamp power supply, resulting in that the circuit cannot be automatically shut down and cannot automatically alarm when the circuit is short-circuited, which will easily lead to damage to the main components of the power supply, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is no short-circuit protection mechanism installed in the traditional traditional LED lamp power supply, resulting in that the circuit cannot be automatically shut down and cannot automatically alarm when the circuit is short-circuited, which will easily lead to damage to the main components of the power supply, increase production costs, and easily Cause a fire, the traditional LED lamp power supply does not have a timing power reduction mechanism, resulting in the LED lamp usually using a constant power to work, resulting in the inability to intelligently regulate the LED lamp power supply, increasing energy loss, wasting non-renewable energy, and increasing pollution to the environment
