recessed luminaires

Recessed ceiling luminaires with various light distributions

Recessed luminaires integrate into the architecture. As a downlight, floodlight, wallwasher or directional luminaire in round or square version they fulfil their task without unduly affecting the ceiling’s appearance.

Criteria for recessed luminaires
- choice of luminaire determines lightcolour and light intensity
- emission angle determines thebeam of light
- cut-off angle or optical cut-off limit glare and increase visual comfort
- recess depth
- size of ceiling aperture

Downlights

Downlights are suitable for attractive, uniform and efficient ambient lighting. They are optimally shielded for good visual comfort. In luminaires with lens system this is achieved by a wide optical cut-off or by an equivalent cut-off angle in darklight reflectors.
Luminaires with quite a narrow beam spread are ideal for high rooms, combining good visual comfort with uniform illumination.

Directional luminaires

Directional luminaires provide highlighting for individual areas or objects with a medium to narrow light distribution.

Wallwashers

Wallwashers have an asymmetrical light distribution that is directed onto vertical surfaces. They provide even illumination for wall or façade surfaces. Special lens systems for lens wallwashers ensure even wall illumination. The light is spread out by the lens and directed onto the wall by wallwasher reflectors. The Darklight reflectors of lens wallwashers are visible from below and are glare-free.

The offset from wall should measure approximately half of the luminaire spacing in order to achieve sufficient brightness on the wall and well proportioned scallops of light. To attain an even illumination on a reference plane, the luminaire spacing should not exceed the mounting height h by more than 1.5:1. An optimal evenness is achieved when a = h.

Downlights provide general lighting for
- entrance areas
- arcades
- passages
- atria
Recessed downlights are inconspicuous architectural details, whereas surface-mounted downlights and pendant luminaires act as room features. They should correspond to the architecture in their arrangement and design.
