an electromagnetic wave that spreads in space and time.

• Sound Waves

• Infrared Waves

• Light Waves

• Optical Waves

a sensation caused by luminance in the visual field that are too bright, cause Discomfort, annoyance, or reduced productivity can result.

• Reflection

• UV Light

• Blue Light

• Glare

It measures the degree that perceived colors of objects, illuminated by a given light source, conform to the colors of those same objects when they are lighted by a reference standard light source.

• Flux

• Luminous Intensity

• Color Rendering Index

• Color Temperature

Defined as the flow of light, Measured in lumens.

• Luminous Intensity

• Luminous Flux

• Efficacy

• Luminance

the act or process of making something clearer or brighter or a device for doing so.

• Light Level

• Diffraction

• Reflection

• Illumination

a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle.

• Luminance

• Luminous Efficacy

• Luminous Efficiency

• Luminous Flux

a family of gas-discharge arc lamps which create light by sending an electrical discharge between two electrodes and through a plasma, or ionized gas.

• Incandescent Lamps

• Flourescent Lamps

• High Intensity Discharge Lamps

• LED Lamps

This is a system designed to give approximately uniform illuminance over the whole of the working plane. The method of accomplishing this result varies from the resultant lighting on the horizontal working plane, must be same, reasonably uniform.

• Task Lighting

• Local Lighting

• Direct Lighting

• General Lighting

These are lighting system that provides illuminance for relatively small areas, incorporating visual tasks. Where visual tasks are essential to achieve a demanded level of illuminance.

• Down Lighting

• Local Lighting

• General Lighting

• Ambient Lighting

Identify this Type of Lighting System:

• General Lighting

• Task Lighting

• Local Lighting

• Combined General & Local Lighting
