Mounting

Technical details for luminaire installation

Both technical and design aspects are important when mounting. If the arrangement of the luminaires is already fixed, then the focus shifts to the mounting detail. Various mounting versions are available for downlights, e.g. surface-mounting, recessed-mounting or pendant suspension.

Suspended ceilings

In the case of flat suspended ceilings, e.g. plasterboard ceilings, the luminaires can almost always be arranged irrespective of the suspended ceiling grid. The luminaires are fixed firmly in the ceiling apertures provided; if necessary, the weight of the luminaire must be carried by additional suspensions fixed onto or in close proximity to the luminaire. If the ceiling is to be plastered, plaster rings are required for the luminaire apertures.

Ceiling

Panel ceilings

For open grid ceilings and honeycomb-grid ceilings there are recessed cassettes available complete with suitable apertures for the recessed mounting of downlights. The cassettes are dimensioned to suit the respective ceiling grids. They can replace a ceiling panel or allow the installation of luminaires between ceiling panels which would otherwise not be suitable to take the static load.

Ceiling channel

Light sources can be mounted in a track ceiling channel in order to integrate them invisibly into the ceiling.

Pendant luminaires

Pendant mounting can be effected in a variety of ways. Light-weight luminaires are usually suspended by the connecting cable. Heavier luminaires require a separate suspension device. This may take the form of a stranded wire cable or a pendant tube, which generally contains the connecting cable.

Ceiling

Concrete ceilings

For recessed mounting into concrete ceilings the luminaire apertures are created when the ceiling is cast. Another possibility is to install prefabricated housings, which are also attached onto the concrete shuttering and remain in the ceiling. It is essential to check that the planned lighting layout is compatible with the structure of the ceiling, whether specific installation locations must be avoided, for example, due to concealed joists or whether the reinforcement of the ceiling should be co-ordinated with the lighting layout.

Luminaires can be mounted onto wall surfaces or recessed into the wall. The latter can be in either concrete or hollow walls.

Floor

Floor

Luminaires for floor or ground installation can be surface-mounted or recessed-mounted. When recess-mounted in the floor or ground, the luminaire cover must be robust and provide protection against the ingress of moisture. Bollard luminaires and mast luminaires may also be used outdoors.
