Direct emission
Direct emission + indirect
The appliance is fitted with a clear plastic
screen featuring an outer micro-prism
pattern designed in order to obtain a
focused luminous emission mostly within a
2x60° cone.
With this technology, Algoritmo
Prismoptic provides comfort lighting
even when the appliance falls within the
observer’s visual cone.
Patent-pending proprietary optic system
made by a thin black square-meshed grid
and by a system of square plano-convex
lenses of appropriate beam angle. The
internal part of the grid is white painted
and has a high reflection coefficient,
so that the light incident on the grid is
retrieved within the body.
A net ‘cut off’ at the required angle is
obtained through this system.
The convex profile of the lens is designed
with images optic techniques, so that the
emission is limited within the 65° required
by standard EN 12464.

Angle luminance equals to 65° and
beyond: <3,000 cd/m2.

The grid positioned over the lenses allows
only the rays falling into the required
output angular limits to be incident to the
lenses.
The rays beyond these limits are
recovered and redirected inside the light
box (if the ray is incident to the white
surface) or cancelled (if the ray is incident
to the black edge).
