The fabrication of LED detecting system

In recent years, the brightness of light-emitting diodes with efficiency has reached a high level, and the next surge is in demand for various types of luminous equipments, such as those can be used in the urban landscape of electronic outdoor billboards, aviation and electronic equipment indicators, which can replace the automobile´s headlights. Particularly in view of the safety factor, such as solid-state components, the hardness of life, and the reliability. Therefore, they become the most suitable alternative with lower maintenance costs. However, when the factory produces a few thousands of light-emitting diode, traditional expensive detecting systems have been used to determine whether their characteristics are good or bad. It is noteworthy that this work will design and fabricate the effective detection and measurement system for the advanced light-emitting diodes, and this system can be used to analyze the stability as well.
