Problems solved by technology

[0002] The light decay of light emitting diode (Light Emitting Diode, LED) is one of the most important problems in lighting applications. Excluding the factors of poor quality and improper use of LEDs, the greatest light decay is caused by overheating of LEDs, and the brightness of LEDs is affected. The working temperature has a greater impact, the higher the working temperature, the lower the brightness of the LED, the serious the light decay, and it will affect the life of the LED

Abstract

The invention is suitable for the field of lighting and provides an LED system. The LED system comprises an LED light source, a detecting unit for detecting a self-illumination parameter and / or an environmental parameter of the LED light source, and a brightness control unit which is connected with the detecting unit, carries out temperature reduction treatment on the environment in which the LEDlight source is positioned according to a detecting result of the detecting unit, and / or adjusts the brightness of the LED light source. By detecting the self-illumination parameter of the LED light source, or by detecting the environmental parameter of the LED light source, the LED system carries out real-time temperature reduction treatment or adjustment of the brightness of the LED light source so as to guarantee the brightness of the LED constant or the brightness of the LED luminous environment constant.

Description

technical field [0001] The invention belongs to the field of lighting, in particular to an LED system. Background technique [0002] The light decay of light emitting diode (Light Emitting Diode, LED) is one of the most important problems in lighting applications. Excluding the factors of poor quality and improper use of LEDs, the greatest light decay is caused by overheating of LEDs, and the brightness of LEDs is affected. The working temperature has a greater impact, the higher the working temperature, the lower the brightness of the LED, the serious the light decay, and it will affect the life of the LED. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an LED system to keep the illumination brightness of the LED constant. [0004] The embodiment of the present invention is achieved in this way, an LED system includes an LED light source, and the LED system also includes: [0005] a detection unit for detecting s...
