Abstract: An electrical receptacle comprises a body comprising an opening and main terminal channels that are spaced apart from each other and from the opening. Electrically conductive main connectors are disposed in the body and spaced apart from each other. The main connectors are disposed in or in alignment with the main terminal channels. A connector is disposed in the body and includes an arcuate shape in or near the opening.

Abstract: An electrical receptacle includes an exterior component and an interior component received inside the exterior component. Main electrical connectors have exterior end portions aligned with main connector openings of the interior component and have interior end portions disposed in alignment with main terminal channels of the exterior component. First and/or second central connectors each having substantially circular portions extend from an end plate of the exterior component and have exterior portions extending to a central connector opening of the interior component. Also featured is a method for electrically connecting the electrical receptacle to a controller device.

Abstract: The embodiment disclosed herein relates to a lighting system that includes an auxiliary lighting circuit for use with an electronic HID ballast. The lighting system comprises a power supply configured to provide power to a high intensity discharge (HID) lamp via an electronic ballast and a ballast power sensing component configured to determine the amount of power drawn by the electronic ballast and to convert this power drawn by the electronic ballast to a scaled voltage that is representative of the power drawn by an HID ballast. A lamp driver component is configured to provide power to an auxiliary lamp via the same power supply when the scaled voltage reaches a triggering threshold. A voltage regulation component is configured to regulate the power delivered to the auxiliary lamp such that the auxiliary lamp power stays within a predefined range.

Abstract: A buck converter generates a direct current (DC) bus voltage at a buck converter output. An inverter circuit is coupled to the buck converter and configured to receive the generated DC voltage and convert the DC voltage into an alternating current (AC) voltage to drive a lamp. A power control circuit is coupled to the buck converter output and configured to provide a control voltage signal to the buck converter so that the buck converter generates the DC voltage and current of a predetermined value. A crest factor reduction circuit is coupled (a) to the buck converter output to sense a rate of change in the generated DC bus voltage, and (b) to the power control circuit to modify the control voltage signal based on the sensed rate of change in the DC bus voltage.

Abstract: A lamp ballast starting circuit and method for a gas discharge lamp is disclosed. The ballast starting circuit includes the inputs of the starting circuit connected to an inverter circuit, the starting circuit generating a pulse at the leading edge of each alternating half cycle of the inverter circuit output, the polarity of the pulse being the same as the polarity of each alternating half cycle of the inverter circuit output. The output of the starting circuit starts a gas discharge lamp.

Abstract: A low-pressure discharge lamp with a double spiral shaped discharge tube including two spiral shaped tube portions. The tube portions define a central axis of the discharge tube. A cold chamber portion connects the ends of the spiral shaped tube portions. The cold chamber portion has a first transversal dimension substantially perpendicular to the central axis which is larger than the diameter of the tube portions. The cold chamber portion further has a second transversal dimension substantially parallel to the central axis. The second transversal dimension of the cold chamber portion substantially corresponds to the diameter of the tube portions.
