An aircraft lighting device includes a circuit board; an LED soldered to the circuit board; an optical element supported by the circuit board and positioned for re-directing at least part of the light emitted by the LED; a magnetic coupling between the circuit board and the optical element; and at least one surface mounted device included in the optical element, such surface mounted device including a pin soldered to the circuit board.

Aircraft lighting device having optical element magnetically coupled to LED circuit board

A lens structure for placement over a light source and for attachment to a circuit board around the light source includes a circuit board engagement portion for being placed towards the circuit board, a recess provided in the circuit board engagement portion for receiving the light source upon attachment of the lens structure to the circuit board, a light entry surface around the recess, a lens body, a light exit surface distal from the circuit board engagement portion, and an attachment structure, the attachment structure being partially molded into the lens body and partially extending from the lens body for attaching the lens structure to the circuit board.

Lens structure for a light unit, light unit, and aircraft comprising such light unit

An aircraft LED light unit comprises at least one printed circuit board which comprises at least one metal core layer and at least one dielectric layer, and at least one LED disposed on the printed circuit board and which comprises an anode and a cathode for electrically coupling to a power source. One of the anode and cathode of the at least one LED is connected to an electrical conductor which is disposed on the dielectric layer and is coupled to a first terminal of the power source, wherein the dielectric layer electrically isolates the electrical conductor from the metal core layer, and the other one of the anode and cathode of the at least one LED is connected to the metal core layer of the at least one printed circuit board, wherein the metal core layer is coupled to a second terminal of the power source.

Aircraft LED light unit

An interior aircraft LED light unit includes at least one printed circuit board, on which a plurality of LEDs are connected to a power source, each one of the plurality of LEDs having a predetermined distance to the power source, and each one of the plurality of LEDs being associated with a respective thermal transfer member having a predetermined size, for transferring heat away from the respective LED, wherein, for at least some of the plurality of LEDs the predetermined size of the respective thermal transfer member varies with the predetermined distance of the LED to the power source.

Interior aircraft LED light unit

An aircraft LED light unit is disclosed that includes a flat electric circuit device having a first main surface, a second main surface and at least one side surface extending between the first main surface and the second main surface, power supply circuitry, disposed in the electric circuit device, at least one heat transport element, disposed in the electric circuit device, and at least one LED. The at least one LED is arranged on the at least one side surface of the electric circuit device, is electrically coupled to the power supply circuitry, and is in heat exchange relationship with the at least one heat transport element.

A lamp for a vehicle, in particular for aircraft, has a housing in which a light source is arranged, with the housing including a first housing part detachably attached to a second housing part, the first and second housing parts being coaxially arranged. Each of the first and second housing parts has at least one projection extending in the axial direction from an edge thereof, for inter-engaging in a corresponding recess of the other housing part. Each projection has a retaining nose protruding in the radial, transverse, direction to form a groove into which a locking element can be inserted to lock the first housing part to the second housing part.
