Algoritmo System LED Controlled Emission
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 Algoritmo
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.
UGR<19
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).
