Abstract
A multi-lamp HID luminaire is provided with a HID ballast. An ignitor that produces a high voltage ignition pulse is coupled to the HID ballast and is also coupled to a plurality of HID lamp sockets that receive HID lamps. A cycling switch is also electrically coupled to the HID ballast and causes a periodic power interruption to the plurality of HID lamp sockets.
Claims21
A HID luminaire assembly for periodically causing a power interruption to a plurality of HID lamps, comprising:
- a HID ballast that receives an input and produces a refined output, said HID ballast having a first input tap and a second input tap for receiving said input and a first output tap and a second output tap for emitting said refined output;
- an ignitor that produces a high voltage ignition pulse, said ignitor electrically coupled to said first output tap and said second output tap;
- a plurality of HID lamp sockets that receive HID lamps, said plurality of HID lamp sockets electrically coupled to one another in a parallel configuration and coupled to said first output tap and said second output tap of said HID ballast;
- a cycling switch electrically coupled to said HID ballast;
- whereby said cycling switch causes a periodic power interruption to said plurality of HID lamp sockets, said periodic power interruption having a duration of more than an extinguishment time period of HID lamps.

- a HID ballast that receives a power input and produces a refined power output, said HID ballast having a first input tap and a second input tap for receiving said power input and a first output tap and a second output tap for emitting said refined power output;
- an ignitor that produces a high voltage ignition pulse, said ignitor electrically coupled to said first output tap and said second output tap;
- a plurality of HID lamp sockets that receive HID lamps, said plurality of HID lamp sockets electrically coupled to one another in a parallel configuration and coupled to said first output tap and said second output tap of said HID ballast;
- a cycling switch electrically coupled to said HID ballast;
- whereby said cycling switch causes a periodic power interruption to said plurality of HID lamp sockets at least once per week, said periodic power interruption having a duration of more than an extinguishment time period of HID lamps;
- a housing enclosing said HID ballast, said ignitor, and said cycling switch.
A HID luminaire assembly for periodically causing a power interruption to a plurality of HID lamps, comprising:
- a HID ballast that receives a power input and produces a refined power output, said HID ballast having a first input tap and a second input tap for receiving said power input and a first output tap and a second output tap for emitting said refined power output;
- an ignitor that produces a high voltage ignition pulse, said ignitor electrically coupled to said first output tap and said second output tap;
- a plurality of HID lamp sockets that receive HID lamps, said plurality of HID lamp sockets electrically coupled to one another in a parallel configuration and coupled to said first output tap and said second output tap of said HID ballast;
- a cycling switch electrically coupled to said HID ballast;
- whereby said cycling switch causes an irregular periodic power interruption to said plurality of HID lamp sockets at least once per week, said periodic power interruption having a duration of less than thirty seconds;
- a housing enclosing said HID ballast, said ignitor, and said cycling switch.
A method of cycling power to a HID luminaire, comprising:
- connecting a plurality of HID lamp sockets that receive HID lamps in a parallel configuration;
- connecting said plurality of HID lamp sockets to the output of an HID ballast having an ignitor;
- electrically coupling a cycling switch to said HID ballast;
- utilizing said cycling switch to cause an irregular periodic power interruption of less than thirty seconds to said HID lamp sockets at least once per week.
