Introduction
Edge-lit LED panels have been successfully used as backlights in display applications including cell phones, tablets, LCD monitors, and TVs. With the decreasing cost and increasing efficiency of LEDs, they are penetrating into general lighting applications. Optical performances of edge-lit LED panels are two characters are contradictory to each other. In different applications, requirements for optical efficiency and surface illuminance uniformity are significantly different. Lighting applications need a high optical efficiency (above 80%) with a wide tolerance of surface illuminance uniformity. In this paper, a light guide design method is studied to achieve user-defined surface illuminance distributions with a high optical efficiency. Simulations results shows that uniform and non-uniform surface illuminance distributions can be achieved with a high optical efficiency up to 88%.
