摘要： A high intensity discharge ballast having an ignitor which shuts off after a predetermined time period has elapsed. The ballast is sensitive to voltage dips in power line voltage and resets a timer whenever the power line voltage drops below a level sufficient for lighting a lamp load. Restart of the lamp load immediately following restoration of power line voltage is achieved without requiring that the power line voltage be removed from the ballast or otherwise reduced to approximately 0 volts before restart can be initiated.

摘要： A thermal protection device for a dual input voltage lighting fixture apparatus which includes a reversible connector for coupling either of two possible input voltages to the appropriate terminal of a winding of a transformer/ballast apparatus via a normally closed contact of a heat responsive thermal switch having a heating element electrically coupled to the reversible connector and thermally coupled to the closed contact. The latter contact opens in response to a level of heat above a given value. The transformer winding has two connection terminals, one of which is a tap point, connected to the reversible connector. The connection scheme provides the same energizing voltage to the heating element for each of the two different possible levels of the input voltage. The apparatus will automatically indicate if the connector is reverse connected for either of the two input voltages.

摘要： An auxiliary lighting system for a high-intensity discharge lamp. In one embodiment, the auxiliary lighting system has an auxiliary light source, an HID lamp status circuit having an input for connection to a status signal representative of the operational state of a high-intensity discharge lamp wherein the HID lamp status circuit determines whether the status signal meets predetermined signal criteria, a switch circuit having a first state that effects application of a voltage source to the auxiliary light source, and a second state that isolates the voltage source from the auxiliary light source, and a control circuit responsive to the HID lamp status circuit for controlling the switch circuit. The control circuit has a first state when the HID lamp status circuit determines that the status signal meets the predetermined signal criteria and a second state when the HID lamp status circuit determines that the status signal does not meet the predetermined signal criteria. When the control circuit is in the first state, the control circuit outputs a control signal for input into the switch circuit that configures the switch circuit into the first state. When the control circuit is in the second state, the control circuit outputs a control signal for input into the switch circuit that configures the switch circuit into the second state.

摘要： An ignitor circuit for a discharge lamp is controlled by a timer to shut-off ignition pulses after a predetermined time if the lamp does not ignite. The timer is controlled by the application of power to the input line. Means in the lamp housing allow the timer to be manually reset during a hot relamping operation.
