A lamp unit is attached to an exterior panel of an aircraft and configured by accommodating a light source into a lamp chamber formed by a metallic housing and a cover attached to the housing. The cover includes a cover body having a light transmissive region that transmits light emitted from the light source and a metallic body support that supports an outer peripheral portion of the cover body. A holding cable that electrically and mechanically connects the housing and the body support is arranged in the lamp chamber. A grounding terminal that electrically connects the holding cable to a fuselage side structural member of the aircraft is provided in the housing.

A tubular LED lighting device (10) comprising an LED, a driver (18) for driving the LED, and an electrical connector (14). The lighting device further comprises a thermally triggered switch (16) for prevention of overheating of the electrical connector. The thermally triggered switch is connected in series between the electrical connector and the driver, and the thermally triggered switch is configured to interrupt current in the event of the temperature of the electrical connector meeting a triggering condition. If a significant degree of arcing occurs the electrical connector will heat up such that the triggering condition will be met and the current flow between the electrical connector and the driver will be interrupted. There is also provided a luminaire (20) comprising the tubular LED lighting device.

A luminaire includes a light emitting diode module, a driver housing, and a hollow connector that connects the driver housing and the light emitting diode module. The driver housing includes a rotatable cap and a driver that provides power to the light emitting diode module. The rotatable cap permits rotation of the hollow connector and the light emitting diode module in order to direct the light from the light emitting diode module in a desired direction. The light emitting diode module includes a plurality of optics wherein each optic covers at least one light emitting diode and at least one vent adjacent to each optic.

An example lighting device has a luminaire. The luminaire includes a laser light source configured to be driven by electrical power to emit laser light rays, a phosphor plate, and a solid medium freeform prism or waveguide. The solid medium freeform prism or waveguide confines incoming laser light ray emitted from the laser light source inside the solid medium until conversion into illumination lighting by the phosphor plate. The solid medium includes an input surface or lens coupled to the laser light source, an output surface, and a highly reflective internal surface to reflect laser light rays to propagate inside the solid medium until emission through the output surface. The phosphor plate is coupled to the output surface of the solid medium to convert the reflected laser light rays into the illumination lighting to emit from the luminaire.
