LED display device for aircraft cabin - has diodes for symbols to be illuminated simultaneously or separately which have different colours when switched on
The display device has a housing (G), closed by a light panel (L), containing several light sources (I). The device also includes characters or symbols (Z) which illuminate separately or simultaneously and which have different colours. The light sources (I) are light emitting diodes. Two flat light conductors (M) are arranged in the housing (G) behind the panel (L). The diodes (I) are connected to conductive tracks on the plates (P). The plates (P) are symmetrical with the conductors (M) and have a plug (S) on one side. An electric plug connector (T) is arranged in the middle of the housing (G) into which the plates (P) can be inserted from both sides. ADVANTAGE - Simple, inexpensive and reliable device which is as flat as possible. Defective light sources can be easily replaced. Increased life span.
