A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

A light tube apparatus includes a tubular housing, a first light source, a second light source, a driver and a controller. The tubular housing having a first light passing window and a second light passing window. The first light source is for emitting a white light from the first light passing window in an illuminating mode. The second light source is for emitting an ultraviolet light from the second light passing window in a sanitizing mode. The driver is for converting an external power source to a first driving current to the first light source and a second driving current to the second light source. The controller is for determining when to enter the sanitizing mode or the illuminating mode based on a stored criterion.

A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

A rotation wheel including a turntable and a motor is provided. The turntable is connected to the motor. The turntable has a first surface used for receiving an incident beam and a second surface opposite to the first surface. The first surface includes a light adjusting surface and a connecting surface. The connecting surface is used to connect the light adjusting surface and the motor. The light adjusting surface is perpendicular to a rotating axis of the motor. At least a part of the connecting surface is neither parallel nor perpendicular to the rotating axis.

An electronic device includes a back frame, a first heat source, a second heat source, a guiding member and a fan. The first heat source is disposed on a first side of the back frame. The second heat source is disposed on a second side of the back frame. The guiding member is disposed on the second side of the back frame. The fan is disposed corresponding to the guiding member. At least part of an airflow path is formed between the first heat source and the second heat source.
