Abstract: A lighting fixture includes a first compartment including a light sealed air plenum and a first lighting source arranged in the plenum to irradiate passing air through the plenum to destroy pathogens. A second compartment is configured to be external to the first compartment. A second lighting source is arranged in the second compartment to illuminate an area adjacent to the second compartment.

Abstract: A junction box includes a bottom portion including a first end portion and a second end portion and a top portion configured to mate with the bottom portion. The top and bottom portions form a first opening to receive a first cable at the first end portion and form a second opening to receive a second cable at the second end portion. Interchangeable connection blocks are included for receiving wires of different gauges to make connections between the first cable and the second cable. A connection block receiving-feature is formed in the bottom portion to secure the connection blocks.

Abstract: A lighting device includes a junction box and a power cord coupled to the junction box. A tape is connected to the junction box and is electrically coupled to the power cord. The tape includes light emitting diodes (LEDs) disposed in sections. Each section includes a repeating light engine block with the LEDs and a circuit repeat joint such that a dimension of the tape can be scaled by cutting the tape at a circuit repeat joint.

Abstract: A lighting device includes a cover portion configured to have a hinged connection for mounting on a housing. The cover portion includes a light emitting diode (LED) and a mixing chamber having a reflective internal surface for receiving light from the LED. A phosphorescent lens is disposed opposite the LED and is configured to reflect light from the LED back to the mixing chamber and to emanate absorbed light from the lens to a surrounding region outside of the mixing chamber. An LED driver circuit is configured to power the LED, the LED driver circuit being electrically connected to a power source. Other embodiments are also disclosed.

Abstract: A preheater unit which includes a chamber for boiler water and a domestic water heating coil is arranged in heat exchange relationship with the exhaust duct of a boiler of a heating system for extracting heat from the flue gases. Boiler water may be shut off to the heat radiating system in the summer although boiler water is fed to the preheater unit both in summer and in winter. The domestic water heating coil within the preheater unit is connected in series flow relationship with the domestic water heating coil interiorly of the boiler. A summer/winter switch is added to the conventional boiler circuitry to enable control of the water circulator by the thermostat in the winter, while the water circulator is operated by the upper limit aquastat during summer operation whenever the burner of the boiler is energized.
