Siluna VT – recessed luminaire with “visual depth effect”
29
with BAP60/Cat.2 louvre
Stereotypical office and
ceiling areas, often lit by
conventional louvre
luminaires will be livened up
by the visual depth effect.
Reduced contrast within the
luminaires gives rise to more
pleasant lighting.
The use of a specially coated
and partially coloured
reflector surface in the
canopy area creates a defined
interplay between colour
effects and white light. The
colour effects are changeable
and could be used to support
a uniform building or
corporate identity concept.
