High visual comfort and optimum light quality - in indoor

E
Quintessence recessed luminaires
take the visual comfort and the
light quality of downlights, wallwashers and directional luminaires
into the outdoor area. The optical
systems of the downlights and
wallwashers achieve high uniformity with good glare control,
making them superb for extensive
illumination in large areas. The
exceptionally wide light distribution of the downlights with a 90°
beam angle and a 40° cut-off pro-
duces highly uniform and glareprotection against moisture and
free light, with luminaires that are dust.
spaced far apart. For precise accentuation, the optical system of the
directional luminaires can be tilted
by 20° and rotated through 360°.
With a protection rating of IP65,
Quintessence recessed luminaires
are the efficient lighting tool for
perception-orientated lighting
concepts in outdoor areas with
canopies and for indoor applications that call for a high degree of

Quintessence Recessed luminaires – Luminaire arrangement
Downlights
Extra wide flood
d
General lighting
For uniform ambient lighting, the
spacing (d) between two Quintessence downlights may be up
to approximately 1.5 times the
height (h) of the luminaire above
the working plane.
Arrangement: d ≤ 1.5 x h
The wall offset should be half the
luminaire spacing.
d
Lens wallwashers
Wallwash
Arrangement: a = d / 2
Wallwashing
For uniform vertical illuminance,
the distance (a) of Quintessence
lens wallwashers from the wall
should be around one third of the
room height (h).
Arrangement: a = 1/3 x h
For good longitudinal uniformity,
the spacing (d) of Quintessence
lens wallwashers may be up to
1.3 times the offset from the wall
(a).
Arrangement: d ≤ 1.3 x a
The optimal wall offset and luminaire spacing for each product are
indicated in the wallwasher tables
in the catalogue and the product
data sheets.
Directional luminaires

Accentuation
Quintessence directional luminaires
accentuate artwork, products and
architectural details effectively.
The ideal angle of tilt (y) for this is
around 20°. The object is modelled
without distorting the effect as a
result of excessive shadowing. It
also prevents shadows cast by the
observer.
Arrangement: y = 20°
