Abstract: Disclosed is a grid lighting system having at least one housing segment with at least one lighting zone. A lighting module is included that has at least one track lighting module and/or at least one non-track lighting module. The lighting zone extends along a first length of the housing segment having at least one first passage to receive the at least one lighting module. The housing segment includes a first power supply segment to be coupled with a designated line voltage outlet to deliver line voltage power to the lighting module in the lighting zone. Each lighting module includes a lighting subzone, with a second passage to receive one or more lighting submodules along a second length. A second power supply segment is provided to couple with the first power supply segment to receive line power and to deliver low voltage to the one or more lighting submodules.

Abstract: The present disclosure provides a control circuit to control power to a load, a typically load being a heating element. The control circuit is preferably comprised of a switch, such as a TRIAC switch, to switch from a first state to a second state. An energy bank, such as a capacitor, is also provided, the energy bank to store energy to power a thermostat when the switch is in a non-conducting state. The control circuit is also comprised of a drive circuit to actuate the switch back and forth from the first state to the second state. The improved control circuit has been shown to have reduced conducted electromagnetic interference, which is advantageous to meet ever stricter government guidelines for circuitry conducted EMI.

Abstract: A line voltage thermostat having a multiple heatsink switch. A total switch may have a semiconductor switch mounted on each heatsink of the multiple heatsink switch. The semiconductor switches of the respective heatsinks may be connected in parallel to represent the total switch. Each of the two or more heatsinks, having a semiconductor switch for switching, and in total conveying the same power as one equivalent switch with one total heatsink, may have higher maximum operating temperatures and higher thermal resistances than twice the thermal resistance of the one total heatsink. The two or more heatsinks may be situated within a housing of the line voltage thermostat, and be easier to distribute in the housing to achieve an efficient layout of a display and control buttons for the thermostat.
