Light attenuation compensation method based on knowledge base

Abstract

This application relates to dimming control of LED lamps and light attenuation compensation control of LED lights, especially to a method of LED light attenuation compensation based on the knowledge base, which is calculated and set by the program in the controller according to the rules of the knowledge base The brightness compensation control parameters of the LED lamp enable the LED lamp to maintain a stable lighting brightness output for a long period of time. This application provides an LED lamp with a luminous margin. It uses artificial intelligence technology to build a knowledge base to monitor all operating data of the LED in real time. According to the operating data and knowledge base, through a certain algorithm, determine the light attenuation compensation. Amount, so that in a long period of time, the LED light can have a stable output, and reduce the light decay speed of the LED lamp as a whole. The advantage of the present invention is that by reserving a certain luminous margin at a relatively small cost during the production of LED lamps, the light decay speed of the entire LED lamp can be very well reduced, the service life of the LED lamp is generally improved, and the LED lamp is reduced. maintenance pressure.

Description

technical field [0001] The present application relates to the technical field of lighting equipment, and in particular, to a knowledge base-based light attenuation compensation method. Background technique [0002] A light-emitting diode (LED) is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. LED lights have the great advantages of high luminous efficiency, energy saving and environmental protection, so they have been widely used in the field of lighting. [0003] The illuminant part of LED is composed of LED chip body and fluorescent material. At the rated temperature, the life of the LED can reach more than 100,000 hours, which can be said to be very long. However, since the LED lamp usually works in different places, it is also a large heat generating body, and some factors will cause the luminous efficiency of the LED lamp to attenuate.

Problems solved by technology

However, since the LED lamp usually works in different places, it is also a large heating element, and some factors will cause the luminous efficiency of the LED lamp to attenuate.

One factor is the quality of the LED product itself: the quality of the LED chip used is not good, and the brightness decays quickly; there are defects in the production process, and the heat dissipation of the LED chip cannot be well derived from the PIN pin, resulting in an excessively high temperature of the LED chip and aggravated chip attenuation

Another factor is the condition of use: LEDs are driven by constant current, and some LEDs are driven by voltage to make the LED decay too fast; the driving current is greater than the rated driving conditions

[0005] Aiming at the problem of short service life of lighting equipment in the related art due to fast light attenuation, no effective solution has been proposed yet
