OLED Requirements for Solid-State Lighting

Materials for Solid State Lighting

Dramatic improvement in the efficiency of inorganic and organic light emitting diodes (LEDs and OLEDs) within the last decade has made these devices viable future energy efficient replacements for current light sources. However, both technologies must overcome major technical barriers, requiring significant advances in material science, before this goal can be achieved. Attention will be given ...

Hybrid Solid-State Lighting Design

The transition from incandescent lighting to more energyefficient options is projected as a major opportunity for solid-state lighting (SSL.) The current prevailing technology for white-light SSL uses a nitride semiconductor blue LED combined with a downconverting YAG:Ce yellow phosphor. The residential use of LED lights presents challenges beyond efficiency, because of very-high color-renderin...

Basic Research Needs for Solid - State Lighting

Solid-State Lighting for Refrigerated Display Cases

The intent of this paper is to initiate a discussion within the community interested in commercial refrigerators, on the possible use of LED lighting in commercial refrigerated and freezer display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. LED is a solid-state light source tha...

Lighting programme and iranian schools lighting requirements

It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...
