An in-grade light fixture is provided with a corrugated housing design. The corrugated housing design enhances structural integrity and the flow of air within the light fixture to facilitate cooling. The light fixture includes an annular door with slots aligned with the corrugations to facilitate the influx of cool air into the housing and the exhaust of hot air from the housing. The light fixture includes a hot-aiming system that allows a tilt optic to be rotated via magnetic force within the light fixture using an external instrument, such as magnetic wand. The beam direction can be rotated using this hot-aiming system without opening the light fixture.

A lighting apparatus includes a printed circuit board. A first light source and a second light source can be mounted on the printed circuit board. A first optical member can receive and redirect light from the first light source, and a second optical member can receive and redirect light from the second light source. A vent aperture can be defined in the printed circuit board, the vent aperture being positioned between the optical members. The apparatus can include first and second thermally conductive sheets thermally coupled to the printed circuit board, the first thermally conductive sheet disposed on a first back side of the first optical member, the second thermally conductive sheet disposed on a second back side of the second optical member. The apparatus can include a housing having a housing vent, the housing vent and the vent aperture defining a first convective path between the optical members.

An LED illumination device for spotlighting includes: a lower case part having a plurality of planar inner side surfaces so that a light-emitting hole on the bottom surface thereof can be a polygonal shape; an upper case part, positioned above the lower case part, for receiving a power supply unit; substrates which are respectively coupled to the planar inner side surfaces of the lower case part and in which LEDs are mounted such that a light-emitting surface can be directed to the central part of the polygon; and a plurality of heat dissipation fins which are protrudingly positioned along the circumference of the lower case part, wherein the spaces between the heat dissipation fins communicate in the longitudinal direction of the lower case part. A case is manufactured as a single structure and components such as a power supply unit, LED-mounted substrates, reflective plates, etc. can be assembled within the case through the light-emitting hole.

An LED light fixture includes an integrally formed unitary housing having a first portion and second portion laterally adjacent to one another. The first and second portions at least partially define separate illuminating and wiring compartments. The illuminating compartment houses a plurality of light emitting diodes and a reflector. The illuminating compartment is partially defined by a frame and a lens mounted to the first portion of the housing. The wiring compartment has at least one wall defined by a door. The door is pivotably attached to the housing. A driver for the plurality of light emitting diodes is mounted to the door for movement with the door.

An illuminating undergarment carries a series of illuminating devices for emitting light and presenting a glow from underneath an outer garment. The undergarment can be tailored in any suitable form factor, such as a slip for placement under a skirt or skirt portion of a dress or other form factors for use under dresses, blouses, pants, etc. The undergarment comprises a series of illuminating device retention members affixed to a surface of the undergarment body. The undergarment body can be sectioned into segments, enabling changes in length and/or shape. The illuminating devices are removably attached to the undergarment by the retention members. The illuminating devices can be arranged in a random pattern, a pattern representing an object, a pattern representing text, etc. and any combination thereof. The illuminating devices can be powered by a portable power supply and controlled by a circuit and/or a switch.
