| Several hundred micro-downlighters, deep-drawn from aluminium reflector material, and an inner reflector ensure glare-free lighting with outstanding luminous efficiency achieving a light output ratio of up to 90 per cent and turning a long, narrow light source into wide and flat illumination. As a result, there is a growing interest in increasing their luminous efficiency through a better understanding of the processes that govem their operation. The device also exhibits a high luminous efficiency of 65 candela per ampere (cd/A) and an external quantum efficiency of 18%, at 1,000 cd/m2, both characteristic features and benefits of phosphorescent OLED technology. |
