luminescence - light not due to incandescence; occurs at low temperatures. light, visible light, visible radiation - (physics) electromagnetic radiation that can produce a visual sensation; the light was filtered through a soft glass window.
Energy efficiency. Energy effectiveness encompasses luminous efficacy of the light source and appropriate power supply in lumens per watt. (lm/W), optical efficiency of the luminaire (light fixture), and how well the luminaire delivers light to the target area. without casting light in unintended directions. The goal is to provide the necessary illuminance in the target area, with. appropriate lighting quality, for the lowest power density.
