    摘要: A control circuit including at least one switch and a plurality of rectifiers for selectively applying a-c utility power to either or both of two remote electrically-powered apparatus at respective first and second states of rectification by means of a conventional two-wire interconnection cable. Where one of the apparatus is of a type, such as a motor, adapted to be powered by a full-wave a-c, the control circuit includes a relay and relay switch responsive to switch-selectable half-wave a-c for connecting the motor to receive full-wave power. In one disclosed embodiment, the two apparatus comprise a composite smoke detector and lamp fixture, and the control circuit provides continuous power at a first state of rectification to the smoke detector portion of the fixture and switch-selectable power at a second state of rectification to the fixture lamp.

    摘要: An electric lamp includes an arc tube assembly mounted in a lamp envelope including a reflector, a lens and a base for connection to an electrical source. The arc tube assembly includes an arc tube having a longitudinal axis aligned with the optical axis of the reflector, a light-transmissive shroud disposed around the arc tube, first and second clips attached to opposite ends of the arc tube, a connection member attached to the first and second clips such that the shroud is retained between the first and second clips in a fixed position relative to the arc tube, and upper and lower electrode supports for mechanically supporting the arc tube in the lamp envelope entirely from the base region and for coupling electrical energy to the arc tube. A support ring is positioned in a heel region of the lamp envelope and is attached to the connection member. The support ring cushions the arc tube assembly when the lamp is subjected to mechanical shock. The connection member includes a connection rod having a first section located outside the shroud between the first and second clips and a second section extending between the first section and the support ring.

    摘要: An electric lamp includes a lamp assembly mounted in a lamp envelope including a reflector, a lens and a base for connection to an electrical source. The lamp assembly includes an arc tube having a longitudinal axis aligned with the optical axis of the reflector, an arc tube support strap attached to one end of the arc tube and including legs extending laterally in opposite directions from the axis of the arc tube, bulb spacers coupled to the legs of the support strap for positioning the arc tube relative to the lamp envelope, a light-transmissive shroud around the arc tube, and electrode supports coupled to the upper and lower electrode leads of the arc tube. The shroud includes an open end which abuts against the legs of the support strap and a domed end which substantially encloses one end of the arc tube. The electrode supports are electrically isolated from the support strap, the bulb spacers and the reflector. The shroud is secured between the support strap and one of the electrode supports. The domed end of the shroud is preferably located at the lens end of the arc tube, but can also be located at the base end of the arc tube.
