Lightgap. Emphasising wall structures for a three-dimensional effect

Grazing light wallwashers accentuate surface texture on walls

Special features of Lightgap
View product description

Very high visual comfort

Due to the small installation dimensions of Lightgap grazing light wallwashers, the luminaires remain concealed and thus support ideal visual comfort. The shielding angle (a) of Lightgap depends on the ceiling height.

Grazing light wallwasher

The especially narrow light distribution of the grazing light wallwashers at short distances from the wall displays relief surfaces in a high quality and uniform way.

Continuous line arrangements are possible

Lightgap luminaires can be mounted directly together to achieve a very uniform distribution of brightness on the wall.

Lightgap emphasises the tactile qualities of architectural materials. The grazing light wallwasher brings out the finest wood or concrete texture as exquisitely as rough surfaces such as natural stone, thereby enabling the luminaire to set off historic features or regional materials. In contrast to conventional wallwashers which give walls a soft character, Lightgap adds an almost tactile dimension through high-contrast light and shadow effects. With its asymmetrical light distribution, the grazing light wallwasher can be positioned up to 10cm close to the wall and still produce an exceptionally uniform beam. The luminaire can be tilted conveniently by up to 10° in both directions. The resulting special rendering of vertical illuminance combines strikingly illuminated texture for scenic effect with efficient room lighting for places such as restaurants and hotels.

Grazing light wallwashers

Grazing light wallwashers

To allow surface textures to come to the foreground of attention, the distance (a) of Lightgap grazing light wallwashers from the wall should be at least 10cm.

Arrangement: a > 10cm

Application: surfaces with a three-dimensional texture, e.g. natural stone walls in prestigious areas.

The shielding angle (α) depends on the position of the suspended ceiling and the size of the cove lighting. A small opening between wall and dry construction narrows the beam on the ground.

Excellent visual comfort

The shallow recess depth of the Lightgap grazing light wallwasher keeps the luminaire concealed to ensure excellent visual comfort.

Dry construction defines light effect

The dry construction detail of the suspended ceiling is used to manipulate the emission angle of grazing light wallwashers. A small opening between wall and dry construction narrows the beam on the ground.

Tiltable by 10°

After installation, Lightgap can be tilted by +/- 10° within the mounting profile to optimise the light distribution along the wall.

Continuous line installation

The Lightgap luminaires can be installed in a continuous line to achieve maximised and uniform illuminance distribution on the wall.

System design

The Lightgap lighting system is available in three lengths for different room layouts. When arranged end to end in a continuous row, the individual luminaires create an elegant and uniform band of light along the wall.
