LED Lighting Glossary |

- Accent Lighting Used in many different ways to illuminate pictures, stairs, lavatories, insides of drawers, or any area that requires small amount of illumination.
- Candlepower (Candela) Basic unit of measuring luminous intensity from a light source in a given direction.
- Cd/m2 Candelas per square meter, measure of luminance (Metric unit of measure).
- Correlated Color Temperature (CCT) A description of the color appearance of a light source measured in Kelvins.
- Diffuser A device to redirect or scatter the light from a source.
- Downwash Lighting An indirect source that emits from behind avalance and gives general wash of light to the floor or lower portions of a wall.
- Electroluminescence the conversion of electrical energy to light energy.
- Emergency Pathway Lighting Used to mark safe pathways of emergency escape routes.
- Footcandles (fc) lumens per square foot, measure of illuminance (English until f measure).
- Footlambert (fL) Candelas per square foot, measure of luminance (English unit of measure).
- Glare Shield Lighting Designed to illuminate a control panel, in such a way that the amount of light and color of light cancels the ambient light.
- Illuminance the density of light striking a surface typeically measured in footcandles or lux.
- Kelvin unit of measure ofabsolute temperature. Measurement not rated in degress.
- LED (Light Emitting Diode) A semiconductor device that emits light through a phenomenon called electroluminescence.
- Luminance Photometric brightness of a surface, typically measured in footlamberts or cd/m^2.
- Luminaire A complete lighting fixture consisting of lamps, housing, optics and wiring.
- Lux Lumens per squaremeter, measure of illuminance (Metric unit of measure).
- Opaqure No transmission of light.
- Recessed Lighting Describes the type of lighting systems which are placed within a ceiling or wall. The cover of the lighting unit is designed to be fluxh against the wall or ceiling.
- Transparent Transmission of light through a material, such that objects or images can be seen as if there were no intervening material.
- Translucent Transmitting light but causing sufficient diffusion to eliminate perception of distinct images.
- Upwasy Lighting Term given to the indirect lighting that emits from behind a valance and gives a general wash of light to the ceiling and upper portions of a wall.
- Wash Expression describing the ay light spreads over a surface.
