Maintenance

Term for the measures taken for the ongoing and effective operation of a lighting installation. It includes replacing lamps, cleaning luminaires and setting the direction of any spotlights. Maintenance is taken into consideration in the design of a lighting system using the parameter light loss factor.

The maintenance of LED lighting systems is usually limited to cleaning the outside of the luminaire, particularly the covers, lenses or reflectors. Any soiling of these reduces the light output ratio, thereby decreasing the required level of brightness and the light effect.
Though not generally required, the LED module should only be replaced by the factory.
The task of the lighting designer is to draw up a maintenance plan that meets the requirements of the given situation and includes the necessary informative literature.
