An LED lighting assembly (1) comprising a cassette (2), a lens, a printed circuit board, PCB, (6) having at least one LED light source mounted thereon, the lighting assembly comprising an LED driver circuit arranged to maintain conduction in the circuit, the PCB using a first amount of power and wherein the LED driver circuit is arranged to simulate use of a second amount of power, the second amount being lower than the first amount. The LED lighting assembly comprises a capacitor arranged to be activated when a voltage across the LED driver circuit is below a first predetermined level. A resistor or resistor/capacitor combination is connectable to a trickle sensor in a passenger service unit (PSU).

An aircraft emergency exit door indication system may comprise a first plurality of light sources, a controller, and a first sensor associated with a first exit door. The first sensor feedback signal indicates an availability for egress through the first exit door. The first plurality of light sources is operated by the controller based upon the first sensor feedback signal. The light sources may be lights that already exist in an aircraft such as ceiling wash lights, sidewall wash lights, floor path lights, dome lights, or passenger service unit lights. The system may include a second plurality of light sources logically separated from the first plurality of light sources based upon its location relative to the first exit door and a second exit door.

An aircraft passenger light includes a reading light unit having a reading light unit and a halo light unit. The reading light unit includes at least one reading light source and is configured for emitting a targeted reading light output. The halo light unit includes at least one halo light source and is configured for emitting a ring shaped halo light output, at least partly surrounding the targeted reading light output.

A reactive illuminated wireless charging surface incorporated into a seating module or worksurface aboard an aircraft or other mobile platform has a translucent exterior surface beneath which a wireless charging device may be positioned and over which a PED may be placed for charging. The illuminated wireless charging surface may incorporate arrays or strips of individually addressable light emitting diodes (LED) or other like luminous devices set into flexible printed control boards (PCB) beneath the exterior surface. The illuminated wireless charging surface may have a display controller for driving the LED arrays in practical or aesthetically appealing ways to provide dynamic visual indication of a charging status, e.g., by adjusting individual LEDs or groups thereof to shift in color or intensity according to predetermined or preprogrammed patterns.

Interior panels for an interior of a vehicle, vehicles, and methods for making interior panels for an interior of a vehicle are provided. In one example, the interior panel includes a first trim section having a first exposed surface configured to face towards the interior. A second trim section that has a second exposed surface configured to face towards the interior is disposed adjacent to and spaced apart from the first trim section to define a gap. A first lighting array that includes light sources is configured to be disposed proximate the gap hidden from the interior by the second trim section. A controller is configured to be in communication with the first lighting array to independently direct each of the light sources to generate light that passes through the gap into the interior and illuminates the first exposed surface to define an illumination pattern.

The control device for the luminaire of a vehicle has an operating power input (401) for receiving operating power, an illumination output (402) for supplying illumination power to one or more light sources (403), and a power converter (404) coupled between said operating power input (401) and said illumination output (402) for converting received operating power into illumination power, which is directed outside. The power converter (404) has a control connection (405). The control device has a control data connection (406) for transmitting control data, and a controller circuit (407) coupled between said control data connection (406) and said control connection (405). The control device has a control power input (408) separate from said operating power input (401) for receiving control power to said controller circuit (407) independently of said operating power, as well as a galvanic isolation (409) between said control circuit (407) and said power converter (407). The coupling from the controller circuit (407) to said control connection (405) passes through said galvanic isolation (409).
