Louvres and reflectors
Reflector and louvre material
The reflectors and active louvres in the Fagerhult range are designed
for maximum eciency and controlled light distribution. This
makes it possible to plan lighting for energy ecient solutions.
A significant factor in obtaining ecient luminaires is the choice
of reflector and louvre material. Fagerhult carefully selects the best
material available on the market.
The louvres and reflectors fitted in Fagerhults T5 luminaires are
constructed from the most eective aluminium available. Many
products for T8 uorescent lamps and compact uorescent lamps
come equipped with reectors and louvres featuring highly reec-
tive material. All done with improved energy eciency and a lower
environmental impact in mind.
Advantages:
Reection factor up to 95 %. •
Reection factor 10 % better than anodised aluminium.•
Better controlled beam path.•
Total lack of colour shifting on surfaces.•
Reduction in unwanted diused beam path. •
The manufacturing process impacts less on the environment than anodising. •
Thin cross blades give
larger light openings and
increase eciency.
No reflections from
the top of the cross
blades are visible in
the side reflectors.
The r5 louvre eectively
guides out the light even
from the back of the
fluorescent lamp.
Sealed top
eliminates
light loss.

r5-louvres
Fagerhult’s double parabolic r5-louvre has been developed for the
T5-uorescent lamp and gives the best eectiveness with regard to
light distribution and eciency. High eciency is directly linked to
energy eciency.
The r5-louvre consists of a double parabolic louvre and a top
reector, which maximises the optical eciency and controls the
luminance in all directions around the luminaire.
The r5-louvre has the following advantages:
The reduction in the thickness of the cross-blades means that the •
light opening’s area has been enlarged by approximately 4 %.
Sealing the top of the cross-blades minimises light losses.•
The curved tops of the cross-blades eliminate unwanted reec-•
tions on the side reflector and gives good mechanical cut o in all
directions.
Metallised aluminium.•
Fixed top reector of specular metallised aluminium. •
The r5-louvre is available as r5, r5 mini and r5 micro.
