System and method for detecting fault of LED illumination equipment

Abstract

The invention discloses a system and method for detecting a fault of LED illumination equipment. The system for detecting the fault of the LED illumination equipment comprises a current measurement component that measures an existing current amount of at least one LED of the LED illumination equipment, an operation parameter measurement component that measures an existing operation parameter of an LED, a storage component that stores an initial state parameter of the LED and a control component that calculates an existing state parameter according to the existing current amount and the existing operation parameter, calculates a state differential value between the existing state parameter and the initial state parameter, judges if the state differential value is greater than an abnormal critical value and determines that the LED works abnormally when the state differential value is greater than the abnormal critical value.

Description

technical field [0001] The present invention relates to a fault detection system, a fault detection method, and a computer-readable recording medium for storing them, and in particular to a fault detection system for LED lighting equipment, and a fault detection system for LED lighting equipment. A method and a computer-readable recording medium storing the same. Background technique [0002] A light-emitting diode (Light-Emitting Diode, LED) is a semiconductor component. At the beginning, it was mostly used as indicator lights, display panels, etc.; with the emergence of white light-emitting diodes, it was also used as lighting. It is a new type of light source in the 21st century, with advantages that traditional light sources cannot compare with, such as high efficiency, long life, and not easy to break. When the forward voltage is applied, the light-emitting diode can emit monochromatic, discontinuous light, which is a kind of electroluminescence effect. Changing the ...

Problems solved by technology

Therefore, if the electrical signals collected by the system are manually observed and faults are judged, the manpower required is quite high, and the management units of general lighting systems cannot have enough manpower to carry out manual observation

If it is directly judged whether the equipment is faulty at each lamp end of the lighting system, it will lead to an increase in equipment cost, and each equipment needs to increase this cost

For medium and large lighting systems, the added cost is high
