An LED light guide bar is a component used to distribute light evenly from LED sources, typically found in lighting applications such as backlighting, display panels, and general illumination. The light guide bar typically consists of a transparent or translucent material, such as acrylic or polycarbonate, designed to efficiently channel and diffuse light from the LED sources placed at one or both ends of the bar. LED light guide bars are valuable in modern lighting solutions for their efficiency and versatility.
