DESCRIPTION

The TLV.420. series was developed for backlighting. Due to

its special shape the spatial distribution of the radiation is

qualified for backlighting.

To optimize the brightness of backlighting a custom-built

reflector (with scattering) is required. Uniform illumination

can be enhanced by covering the front of the reflector with

diffusor material.

This is a flexible solution for backlighting different areas.
