专利汇可以提供Incandescent-high intensity discharge lamp lighting system专利检索，专利查询，专利分析的服务。并且A lighting system is disclosed utilizing an improved lamp including an exterior glass envelope which is affixed to a terminal fastener, and which contains an arc tube (for providing a high intensity discharge) as well as a filament (for use in a system furnishing auxiliary incandescent illumination). The arc tube incorporates starting and primary discharge electrodes. A limiting resistor is also contained in the envelope, serially connected with the starting electrode. As disclosed, the lamp is incorporated in a system such that the incandescent filament furnishes illumination indepdendent of the arc tube. For further control, a heat-operated switch may be incorporated.，下面是Incandescent-high intensity discharge lamp lighting system专利的具体信息内容。

权利要求

1. A high-intensity lamp comprising: arc tube means defining a light-transmissive closure for supporting an illuminating gaseous discharge; first and second discharge electrodes affixed in spaced-apart relationship within said arc tube means; a starting electrode means affixed in said arc tube means in glow-discharge relationship with one of said discharge electrodes for initiating an illuminating discharge between said discharge electrodes; a light-transmissive envelope enclosing said arc tube means; connection means for providing first and second terminal contacts exterior of said envelope for connection to said electrodes; an incandescent filament means affixed in said envelope and connected in cooperative relationship with one of said electrodes; and a third terminAl contact external of said envelope, connected to said incandescent filament means whereby said filament means is energized separately from said arc tube.

2. A high-intensity lamp according to claim 1 further including a resistance connected in series relationship with said starting electrode, and positioned inside said envelope means.

3. A high-intensity lamp according to claim 1 further including a heat-operated switch means positioned in heat-transfer relationship to said arc tube means and connected in series relationship with said incandescent filament means.

4. A high-intensity lamp according to claim 1 wherein said incandescent filament is of a wattage of less than one eighth of that of said discharge electrodes.

5. A high-intensity lamp according to claim 1 wherein one of said terminal contacts comprises a fastener terminal means.

6. A high-intensity lamp according to claim 1 wherein said arc tube means enclosing said electrodes is composed of quartz.

7. A high-intensity lamp according to claim 1 incorporated in a system comprising: a ballast circuit for connecting said gaseous discharge lamp to a source of power and limiting the flow of current therethrough; means for providing a base level potential somewhat intermediate the extreme potential levels occurring across said discharge electrodes; and means for connecting said incandescent resistance wire means to be energized by the potential developed across said discharge electrodes by said ballast circuit, referenced to said base level potential.
