Example implementations relate to decorative display panels for aircraft interiors. An example display panel can include a display shell having one or more openings arranged to form a decorative design and a translucent layer coupled to the display shell. The translucent layer can extend across the openings in the display shell. The display panel can also include a lighting interface coupled to the translucent layer and configured to illuminate one or more portions of the translucent layer positioned relative to the openings in the display shell. The display shell may be coupled to the interior panel such that the translucent layer and the light interface are positioned in between the display shell and the interior panel from an aircraft. In some examples, the lighting interface can illuminate the display panel using different colors and patterns based on desired visual effect and/or operational status of the aircraft.

Example embodiments relate to luminaire head assemblies with brackets. One example luminaire head assembly includes a housing provided with a socket assembly. The luminaire head assembly also includes a light source arranged in the housing. Additionally, the luminaire head assembly includes a bracket releasably attached to the housing. The bracket is configured to fix the housing to a pole. The bracket has a first end for connection to a pole or pole connector and a second end attached to the housing. The bracket is provided with a through-hole at the second end. The socket assembly extends at least partially in the through-hole.

A compact conditioning system for controlling a volume, comprises: (a) at least one light source, said light source being coupled with a replaceable focusing lens; (b) at least one fan; (c) at least one temperature sensor; (d) control circuitry adapted to receive inputs from said sensor(s) and/or from a user, and to operate said light source(s) and/or said fan(s) as a result thereof; and (e) a housing suitable to house said light source, fan and control circuitry and adapted to be positioned at the top of a structural element defining a closed space.

Disclosed is a lamp for a vehicle, the lamp including a light source unit including a light source and a board, an optical fiber disposed forward of the light source unit, an inner lens disposed between the light source unit and the optical fiber, provided to be in close contact with the board, and configured to fix or hold one side of the optical fiber, a heat sink disposed rearward of the light source unit and provided to be in close contact with the board, an elastic member disposed rearward of the heat sink, provided to be in close contact with the heat sink, and having elasticity, and an aiming bolt disposed rearward of the elastic member and configured to penetrate the elastic member and press a rear surface of the heat sink, in which the aiming bolt is movable in a forward/rearward direction.

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adjacent a bottom thereof. The light source may be a light-emitting diode.

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.

Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.
