2. Direct and aimed general lighting
NON-DIFFUSED
•produces an even illumination on the horizontal
working plane.The architecture is visible and it is
possible to orientate oneself and work in the room.
•The directed light produces good modelling and
brilliance.
•Directed light enables good even and uniform general
visibility and appreciation of form and surface texture.

8. Direct and aimed general lighting
DIFFUSE
•Direct diffuse light produces a soft illumination
with little shadow and reflection.
•The limited formation of shadow results in weak
modelling capabilities. Shapes and surface textures
are only slightly emphasized.

9. Direct, diffuse general lighting for:
- working areas
- multifunctional rooms
- museums
- exhibitions
- pedestrian traffic areas
Preferred luminaire groups:
- light structures
- downlights
- wall-mounted downlights
- luminous ceilings

17. •Indirect general lighting uses a ceiling, wall or other
surface as a secondary reflector.The brightening of
these surfaces that delineate the room or area gives
an open spatial impression.
•Compared to direct illumination, a considerably
higher luminous flux is necessary for achieving the
same illuminance on the working plane.

44. •Accent light emphasizes individual objects or
architectural elements using narrow beams of light.
Bright points in dark surroundings attract attention.
•They separate the important from the unimportant,
allowing individual objects to come to the fore.
•The focused light produces pronounced shadows and
good modelling ability, as well as brilliance.
•A narrow beam and a high brightness contrast to the
surroundings give the object particular emphasis.

47. Accent lighting for:
- exhibitions
- museums
- sales and presentation areas
- restaurants, cafés, wine bars
- working areas
Preferred luminaire groups:
- spotlights
- contour spotlights
- directional downlights
- directional recessed floor luminaires
- task lights

62. Wallwashing is a popular name for a lighting design technique for
illumination of large surfaces. It is mainly used with contemporary
architecture; in public cultural buildings, museums and galleries;
and in landscape lighting.
Most of what one actually sees, entering a room, are the vertical
surfaces.The illumination requires asymmetric lighting
fixtures, which in a number of 3 or more in a line, can produce
evenly illuminated walls.

68. The specially designed
reflector of theTFL
Wallwasher provides
homogenous illumination of
the vertical plane.To
achieve a uniform
brightness distribution on
the wall, the recessed
luminaires can be attached
directly to one another.

69. Each luminaire has
removable end plates to
allow a row of wallwashers
to be mounted as a
continuous arrangement
without gaps. To achieve a
uniform brightness
distribution on the wall, the
luminaires can be attached
directly to one another.
