Illumination arrangement for display tables - has LED(S) on board behind front panel illumination fixed transparent characters

摘要

An illumination arrangement for a display table with transparent fixed characters let into an opaque front plate (10) has a light source mounted behind the plate. Light emitting diodes (34) forming the source have transparent, pot-shaped covers (38) with convex mirrors (44) at the end towards which the light from the diodes is directed. The diodes are mounted on a plate (14) behind and parallel to the front plate so as to provide essentially uniform illumination of the characters. USE/ADVANTAGE - Improved quality of illumination of display tables for day and night reading, esp. for aircraft cockpit instrument panels.
