An aircraft passenger service unit placard comprising an integrated unit adapted to be retrofitted to an existing passenger service unit having a bi-pin lamp connection, the integrated unit comprising at least a first signage area and having at least one low energy illumination means arranged to illuminate the signage area, wherein the low energy illumination mean is optionally an LED unit and wherein the integrated unit comprises a first layer and a second layer separated by a light guide and wherein the illumination means is arranged as a side light in the light guide between the first layer and the second layer, the integrated unit further comprising at least one flexible connector arranged and adapted to connect to the bi-pin connection.

A vehicle lighting system is provided primarily for use with emergency response vehicles. The vehicle lighting system includes at least one luminescent planar sheet affixed to a vehicle's mounting surface. The luminescent planar sheet includes a non-luminescent printed circuit board in the shape of a letter or number which has a top surface of a color which contrasts with the mounting surface's color. The luminescent planar sheet includes a plurality of light emitting LEDs which are surface mounted upon the printed circuit board so as to be arranged in the shape of the desired letter or number with the LEDs covering no more than 20% of the printed circuit board's top surface. Preferably, the LEDs cover no more than 7% the printed circuit board's top surface.

According to principles of the present inventive concepts, a dial-in board comprises a housing configured to house a digital display, a control module, and a rechargeable battery all within a single, portable, self-contained housing unit that mounts readily to a racing vehicle without the need for external wiring. The digital display is preferably a multi-colored LED display configured to display a dial-in time of the racing vehicle in any of multiple desired colors. A control module controls operation of the digital display, and the control module and the digital display are both powered by the rechargeable battery. The control module may further include a dimmer capable of controlling a brightness of the digital display. The control module may be controlled by a control panel arranged on the housing and/or through an external device that communicates with the control module wirelessly, such as through Bluetooth communication.

A component (6) for a passenger cabin (2) of a passenger aircraft (4) contains a base body (8) with a surface (10), and a layer structure (12), which is applied to the surface (10) and contains at least two layers in the form of at least one active layer (14) and an adhesive layer (16) arranged between the active layer (14) and the surface (10), wherein the active layer (14) contains at least one surface section (18a-c) which is formed from an electrically controllable colour-changing film (20), wherein at least a part of the colour-changing film (20) forms a visible surface (22) for the intended purpose in the passenger cabin (2).

A vehicle lighting system is provided primarily for use with emergency response vehicles. The vehicle lighting system includes at least one luminescent planar sheet affixed to a vehicle's mounting surface. The luminescent planar sheet includes a non-luminescent printed circuit board in the shape of a letter or number which has a top surface of a color which contrasts with the mounting surface's color. The luminescent planar sheet includes a plurality of light emitting LEDs which are surface mounted upon the printed circuit board so as to be arranged in the shape of the desired letter or number with the LEDs covering no more than 20% of the printed circuit board's top surface. Preferably, the LEDs cover no more than 7% the printed circuit board's top surface.

A window assembly is provided herein. The window assembly includes an emblem assembly configured to couple to a window of a vehicle. An indicia is disposed within the emblem assembly signifying a first operational mode of the vehicle. A reflective layer is disposed on the emblem assembly. The indicia is visible when the vehicle is operating in the first operational mode and non-visible in a second operational mode.

A lighting assembly of a vehicle is provided herein including a windshield and an electroluminescent member sealed within the windshield and configured to illuminate in response to applied electrical power. A reflector is optically coupled to the electroluminescent member and is configured to enhance the brightness thereof. A fit is coupled to the windshield and is positioned to at least partially conceal the electroluminescent member from a driver of the vehicle.

A window for a vehicle is provided herein. The window includes a light guide disposed between an outer panel and an inner panel. A light source is optically coupled with the light guide and is configured to direct excitation light towards a luminescent structure. The luminescent structure luminesces in response to receiving the excitation light. A controller is configured to illuminate the light source when an electronic device having an application thereon is in operation.

An electroluminescent vehicle emblem and a method for illuminating a vehicle emblem includes a base layer, a cover layer, and an electroluminescent light source, which can be one or two electroluminescent assemblies. When the electroluminescent light source is not activated, the cover layer has an opaque appearance. When the electroluminescent light source is activated, light emitted from the electroluminescent light source is transmitted through the cover layer and emitted from a front of the vehicle emblem. Light is also emitted from a back of the vehicle emblem that is opposite from the front of the vehicle emblem to provide back lighting to the vehicle emblem.

A badge is provided herein. The badge includes a viewable portion having indicia thereon. A plurality of first LED sources is configured to emit light toward the viewable portion. A light guide extends between the viewable portion and the first LED sources. A plurality of second LED sources is configured to emit light toward the viewable portion. The first LED sources illuminate a first region of the viewable portion and the second LED sources illuminate a second region of the viewable portion.
