Example Embodiment

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] At present, there is a technical problem of attenuation of the luminous flux of LED lamps. The traditional solution is to use LED lamps with higher luminous flux, but the cost is high; or artificial intervention to adjust the luminous flux of LED lamps, but the adjustment is cumbersome.

[0028] In order to solve the technical problem that LED lamps cannot properly solve the attenuation of luminous flux, please refer to figure 1 This embodiment ...

Abstract

The invention relates to the technical field of LED driving power supplies, and particularly relates to a driving power supply power regulation system for compensating LED light decay and a driving power supply power regulation method thereof. The system comprises an LED driving power circuit module which is connected with an LED lamp and an MCU control module which is used for controlling the output power of the LED driving power circuit module. The MCU control module comprises an MCU power supply conditioning module, an MCU module, an LED power control PWM conditioning module and a power supply conditioning circuit module for maintaining the MCU to save the accumulated work time after disconnection of the LED driving power supply. The objective of the invention is to provide the power supply power regulation system for compensating LED light decay and the power supply power regulation method thereof. Manual intervention in LED light decay regulation is not required in the technical scheme so that the system and the method are convenient and the energy consumption can be saved.

Description

technical field [0001] The invention relates to the technical field of LED driving power supply, in particular to a driving power regulation system and a method thereof for compensating LED light decay. Background technique [0002] At present, LED lamps have been running for a certain period of time, and the luminous flux has the characteristic of attenuation. The service life of the lamp has not yet been reached. The luminous flux has decayed to the point that it does not meet the lighting requirements of certain specific places. [0003] There are two traditional methods to solve this problem. One is to use LED lamps with higher luminous flux to meet the requirements of predetermined luminous flux after the luminous flux decays even after reaching the service life, but the energy consumption is relatively large, which cannot meet the goal of energy saving. ; Second, when the light attenuation reaches a certain level and does not meet the luminous flux requirements, it is ...
