Self-adaptive control device and self-adaptive control method for LED electric light source based on optimal light effect

Abstract

The invention discloses a self-adaptive control device and a self-adaptive control method for an LED electric light source based on optimal light effect. The self-adaptive control device is characterized by comprising a rectifier module, a PFC module, an LED module, an MCU control module, a temperature detection module, an illumination detection module, a constant current driver module and a current detection module. According to the self-adaptive control device and the self-adaptive control method, the working current of the LED electric light source can be automatically adjusted through the MCU control module, so that the heat generated by the LED electric light source can be reduced, the working temperature of the LED electric light source is reduced, and then the light effect of the LED electric light source is improved, and the intelligentization of the LED electric light source is improved.

Description

technical field [0001] The invention relates to an adaptive control device for an LED electric light source based on optimal light efficiency and an adaptive control method thereof, belonging to the field of semiconductor lighting. Background technique [0002] The energy crisis, the greenhouse effect, and the deteriorating ecological environment are always reminding people that the earth is already unbearable. It has become the consensus of the world to change people's energy acquisition methods and improve energy utilization. [0003] Because in the world's electricity usage structure, lighting electricity consumption accounts for 19% of the total electricity consumption; in my country, lighting electricity consumption accounts for about 12% of the country's total electricity consumption, and my country's annual lighting electricity consumption growth rate (conservative estimate) About 5%. Although the proportion of lighting electricity consumption varies due to different ...

AI Technical Summary

Problems solved by technology

[0006] 1. The heat dissipation technology of high-power LED is not mature enough, and the rise of temperature will accelerate the light decay of LED, which directly affects the life of LED;

[0007] 2. Ordinary LED light sources on the market generally work in their rated state, and the light effect is not in the best state;

[0008] 3. Once the ordinary LED light source is finalized, it can only work in one state, and cannot intelligently adjust its working state
