Application of Solid State Lighting Sources in Plant Factory

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...

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 ...

Energy-efficient control of solid-state lighting

Lighting control is in the midst of radical change. Presentday state-of-the-art lighting systems tend to be extremely complex. They exhibit very flexible actuation possibilities with many degrees of freedom that can be exploited to answer dynamiclighting needs. However, user interfaces to these systems are woefully lacking. They are frequently denigrated to a panel of buttons that select partic...

Basic Research Needs for Solid - State Lighting

Solid-state lighting: an energy-economics perspective

Artificial light has long been a significant factor contributing to the quality and productivity of human life. As a consequence, we are willing to use huge amounts of energy to produce it. Solid-state lighting (SSL) is an emerging technology that promises performance features and efficiencies well beyond those of traditional artificial lighting, accompanied by potentially massive shifts in (a)...
