Patent DE-3739643-A1 (DE)
Inventor: HULME ANDREW JOHN
IPC: B64D43/00
Filed: 1987-11-23
Abstract: A device for illuminating display legends such as aircraft instrument consoles or panels includes at least two light channels, each channel 10, 11 being associated with at least one light source 8, 9 for providing light within the channels. Means, e.g. a prism 15, are provided for directing light output from each light channel to a common legend bearing area 7. The arrangement is such that the light output from one channel is of a broad frequency spread predominantly falling outside the infra-red (I.R.) area and within the photopic area of the electro-magnetic frequency spectrum, e.g. by the use of an I.R. filter 12, and that light output from the other channel has a broad frequency spread covering at least the photopic area of the electro-magnetic frequency spectrum. The power supply to the light sources is selectively energisable to activate one or other of the light sources. <IMAGE>
