A combination assembly or apparatus of a ceiling fan and heater. The combination assembly or apparatus includes a ceiling fan, a heater, a fan to blow air across the heater, a translucent band, motor driven rotating reflective foils each having mounted therein a light source (e.g. an LED) to shine through the translucent band to give a motion effect like a flickering.

An HVAC register or return grille with an integrated nightlight, a battery-operated nightlight module and an area on the grille suitable for mounting the nightlight module. The nightlight module is operatively coupled to the grille and fitted with motion sensing technology to activate the light when a user nears the device. The integration of nightlight technology into HVAC grilles allows for a discrete nightlight location and enhances the utility of conventional HVAC register and return grilles.

The two or more negative temperature coefficient devices are positioned in a negative feedback loop of the single amplifier.

A heating unit includes a housing defining a thermal cavity and has a first longitudinal edge and an opposing second longitudinal edge, a reflector assembly disposed within the thermal cavity, a heating element, and a lighting element. The housing defines a vent positioned at least one of laterally between a central longitudinal plane of the housing and the first longitudinal edge and laterally between the central longitudinal plane and the opposing second longitudinal edge. The reflector assembly is coupled to an interior surface of the housing. A spacer is positioned between the reflector assembly and the interior surface forming an air gap therebetween. The heating element extends within the central longitudinal plane and is at least partially surrounded by the reflector assembly. The lighting element is positioned along at least one of the first longitudinal edge and the opposing second longitudinal edge such that the vent is positioned laterally between the lighting element and the heating element.

The present disclosure provides an airway device. The airway device includes: a main housing provided with a suction port and a blow port; an air passage having a cylindrical shape, and having an inner circumferential surface defining an air flow path from the suction port to the blow port; and a lighting unit for illuminating the inner circumferential surface. The airway device can be used alone or together with blower and the like to form a ceiling mounted ventilation fan. Compared with the prior art, the ventilating fan device has the advantages of small air pressure loss, high ventilation efficiency, high lighting efficiency and convenient maintenance.

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.
