Lightgap. Emphasising wall structures for a three-dimensional effect

Grazing light wallwashers accentuate surface texture on walls

Special characteristics
Product description

Excellent visual comfort

The shallow recess depth of the Lightgap grazing light wallwasher keeps the luminaire concealed to ensure excellent visual comfort. The shielding angle (α) of Lightgap depends on the ceiling height.

Continuous line installation

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

Grazing light wallwashers

The very narrow light distribution of the grazing light wallwashers positioned close to the wall uniformly illuminates relief-like surfaces, making elegant materials highly visible.

Dry construction defines light effect

The dry construction detail of the suspended ceiling is used to manipulate the emission angle and to define a beam that spreads light from the ground. A small space between wall and dry construction ceiling results in a narrow beam.

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

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.
