Abstract: The invention relates to a light sign (10) for displaying an instruction and/or guidance for ground airplane traffic at an airport, comprising a casing (20) with a transparent display panel (21) for representing an instruction and/or guidance symbol (Z), and a light source arranged inside the casing (20) with at least one luminescent diode (32) for illuminating the display panel (21). A diffusion panel (22) is made for scattering and/or back-scattering incident light, wherein the light source is arranged between the display panel and the diffusion panel. The at least one luminescent diode (32) is aligned on the diffusion panel (22) so that the display panel (21) is not illuminated directly, but indirectly by back-scattering of the light emitted from the at least one luminescent diode by the diffusion panel (22).

Abstract: Elevated airfield lighting device (10), comprising a main body (11) securable to a support (14) enabling the main body (11) to be fixed at an elevated position from ground (15), and at least one light unit (12, 13) comprising at least one LED (17), wherein the main body (11) encloses an electronic circuit for powering and driving the LED and comprises a first heat sink (110) thermally coupled to the electronic circuit and wherein the light unit comprises a second heat sink (120, 130) for dissipating heat generated by the LED. The lighting device (10) is characterised in that the light unit (12, 13) is formed as a separate body from the main body (11) and comprises a front (12, 132) for transmitting light emitted from the LED and a back comprising a rear surface at which the second heat sink is provided.

Abstract: Disclosed is a glide-angle light for approach guidance of aircraft, comprising a housing with a light outlet opening in which a light channel with an optical axis is arranged, along which a light source for production of a light beam, a colored filter for splitting the light beam into a filtered beam component and an unfiltered beam component and a lens arrangement for focused emission of the light beam through the light outlet opening are arranged. Only a single light channel is arranged in the housing so that the glide-angle lights according to the invention can be produced at considerably less cost.
