Abstract

A novel LED backlight device is introduced in this paper, which is mainly used for transparent or translucent glass bottle detection relevant to machine vision. A special controlling and drive circuit is adopted in this LED backlight device to realize independent control of each color and rapid and convenient change of many colors and luminance. Because the area of LED backlight can be changed at random according to the size of tested product, many application requirements will be met easily. On the other hand, safe and effective cooling equipment is used to improve stability of the whole system.
