A modular PC cooling pump for use in a personal computer is disclosed, according to certain embodiments. The modular PC cooling pump comprises a plurality of stackable interchangeable modules, according to certain embodiments.

A luminaire for lighting and for distribution of conditioned air within a space includes a housing having a lighting element, a duct opening, and at least one air vent coupled to the duct opening. The at least one air vent is configured to deliver conditioned air to the space. A method of controlling light and conditioned air delivery within a space, by a single combined lighting and conditioned air fixture, includes providing control and power signals to a controller coupled to the single combined lighting and conditioned air fixture, controlling lighting functions via the controller, and controlling conditioned air functions via the controller.

An apparatus includes a high side heat exchanger, a first load, a second load, a first plurality of lights, a second plurality of lights, a third plurality of lights, and a controller. The high side heat exchanger removes heat from a refrigerant. The first load uses the refrigerant to cool a space proximate the first load. The second load uses the refrigerant to cool a space proximate the second load. The first plurality of lights is coupled to the high side heat exchanger. The second plurality of lights is coupled to the first load. The third plurality of lights is coupled to the second load. The controller receives an indication of a detected malfunction in at least one of the high side heat exchanger, the first load, the second load, and in response to the indication, activates the first, second, and third plurality of lights.

A system includes a first power cord and at least one heated repellant dispersal unit electrically connected to the first power cord that increases an evaporation rate of a repellant within the heated repellant dispersal unit.

A flame simulating assembly for providing a moving effect of flames. The assembly includes a light source; a flicker element disposed in the path of the light source configured and arranged to reflect light from the light source; and an imaging wall. The imaging wall is disposed above the light source and includes a front facet and at least one additional facet. The front facet has an upper portion disposed forward of a lower portion thereof and the at least one additional facet extending rearward from the front facet. Light from the flicker element is occluded by the front facet to provide a more realistic fire shape. The fire shape appears wider at the base than at the top.

An air conditioner includes a main body, a blower fan disposed in the main body, a discharge panel including a main outlet configured to discharge air discharged from the blower fan and a plurality of fine outlets provided near the main outlet, an opening and closing member configured to move in forward and backward directions and open and close the main outlet, and a lighting apparatus disposed on a back surface of the opening and closing member and configured to emit light to a back side thereof. Since an area illuminated by the lighting apparatus is changed according to a position of the opening and closing member, a user intuitively identifies an operational state of the air conditioner.

A fan includes a fan frame, an impeller, a plurality of blades and a light emitting unit. The impeller is rotatably coupled with the fan frame and includes a light diffuser ring. The plurality of blades is connected to the light diffuser ring. The light emitting unit is mounted in the fan frame and shines light on the light diffuser ring.

At least one light socket is electrically connected to a power cord and at least one heated repellant dispersal unit is electrically connected to the power cord and increases an evaporation rate of a repellant drawn by a wick from a fluid pod affixed to the heated repellant dispersal unit.

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.

A light source module and an air conditioner including the light source module. The light source module includes: at least one light source emitting sterilizing light in a wavelength band capable of sterilizing pollutants; a substrate on which the light source is mounted, the substrate being electrically connected to the light source; and a light guide guiding a traveling direction of the sterilizing light emitted from the light source. The light guide may guide the sterilizing light such that a beam angle of the light source module becomes narrower than a beam angle of the light source.
