Description

Device and method for diagnosing LED module failure

The present invention relates to a technique for diagnosing a failure of an LED module, and more particularly, diagnosing whether an LED module installed for an outdoor electric signboard (or outdoor lighting fixture) has a failure based on the measurement result based on the operating environment, , relates to an apparatus and method for diagnosing a failure of an LED module capable of alerting this to a preset communication terminal.

Recently, due to various advantages of LEDs (eg, energy saving, long lifespan, eco-friendliness, etc.), it is widely applied to outdoor (outdoor) electric signs and outdoor lighting equipment.

That is, it is a recent trend to build an outdoor electric signboard or outdoor LED lighting equipment using LED elements. In such an outdoor electric signboard, the LED module is partially damaged or the LED module is damaged due to the external operating environment (or use environment), etc. Individual LED elements constituting the components are frequently damaged.

Conventionally, a manager (or an operator) visually monitors the operation status of an outdoor electric sign board or outdoor LED lighting equipment at a remote control center (for example, remote monitoring using CCTV, etc.) or an electric sign manager directly visits the site. The failure of the LED module is diagnosed by visually observing it.

However, the conventional method for diagnosing LED failures has a fundamental problem in that real-time failure diagnosis is difficult and an administrator's diagnostic time required for failure diagnosis is unnecessarily excessive.
