A ceiling light or wall light having a connection to a typical lighting power circuit, having an integrated heating fan function, and an intelligent control for simple operation and functions for saving energy. In order to avoid a cumbersome variation of the heating possibilities (for example, the installation of a heater, placement of an additional heater, and modification of the control of an existing heater), a replacement of the usually already existing lighting takes over this functionality. The device includes a common housing, that contains at least one lighting element, at least one electrical heating element, at least one fan, and at least one programmable electronic controller, by which the lighting, the fan and the heater are controlled and/or regulated, together with and/or separate from each other. All rooms of a building which have lighting and are to be heated only for a limited period may be part of the area of application.

Disclosed embodiments relate to a combination axial fan, LED lighting system and electric blue killer. The disclosed systems may include a housing forming an air chamber and an axial fan. The fan may include a fan cavity having an air diversion mechanism to direct air from the fan cavity toward the lighting, fan and electric bug killing components. The inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. The LED light fixture emits a blue or light blue light which attracts bugs. Moreover, disclosed embodiments include one or more electric bug killing devices to kill any bugs as air flows through the air chamber. The present invention may also include grow light fixture in the housing.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include 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 inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. Moreover, disclosed embodiments include one or more UV light sources which irradiate contaminants as air flows through the ceiling tile.

A heating unit includes a housing defining a thermal cavity, a reflector assembly disposed within the thermal cavity, and a heating element disposed within the thermal cavity. The reflector assembly includes a first reflector coupled to an interior surface of the housing and a second reflector coupled to the first reflector. The first reflector is spaced from the interior surface forming a first air gap therebetween and the second reflector is spaced from the first reflector forming a second air gap therebetween. The heating element is at least partially surrounded by the reflector assembly.

An air-conditioning light-emitting system includes: air conditioners; light emitters; a first communication means that connects the air conditioners and that causes the air conditioners to communicate with each other; a plurality of second communication means that each connects one of the air conditioners to one of the light emitters and that causes the one of the air conditioners to communicate with the one of the light emitters; and a controller that controls the light emitters by using the first communication means and the second communication means.

Embodiments of the invention provide an illumination grille assembly comprising a frame and a ventilation grille coupled to the frame, and a plurality of light-emitting diodes coupled with the frame and at least partially covered with a light transparent cover. Some embodiments of the invention provide a lighting and ventilating system including a main housing including an inlet through which air can be received within the main housing and an outlet through which the air can exit the main housing. A blower assembly can be supported in the main housing and it can be operable to generate a flow of air. In some embodiments, an illumination grille assembly can be coupled to the main housing to allow fluid to flow through the illumination grill assembly to the main housing. In some embodiments, the set of illumination devices can be configured and arranged to emit light through the light transparent cover.

A heat dissipating device includes a bottom assembly, a first light guide positioned on the bottom assembly, a first light assembly positioned on the first light guide, and an outer cover positioned on the bottom assembly and at least partially enclosing the bottom assembly, the first light guide, and the first light assembly. The outer cover defines a first opening on a top surface thereof, at least a portion of the first light guide is received in the first opening, and light from the first light assembly is emitted from the heat dissipating device through the exposed portion of the first light guide.

An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack. The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle. An electrical enclosure assembly includes a receptacle and a cover member configured as an air foil.
