Devices that control the distribution of the light emitted by a lamp or lamps and that include all the items necessary for fixing and protecting the lamps (and sometimes the gear, too) and for connecting them to the electricity-supply circuit [1].

Luminaire Characteristics

The principal characteristics of luminaires can be listed under the following headings:
  • Optical

  • Mechanical

  • Electrical

  • Thermal

  • Aesthetics

Optical Characteristics

The optical characteristics of a luminaire determine the shape of its light beam, or light-output distribution. The light distribution of a luminaire defines how the luminous flux radiated by the lamp or lamps is distributed in the various directions within the space around it. Different lighting applications require different light distributions and thus different luminaires.

The desired light distribution of a luminaire is obtained through the application of one or more of the...
