Abstract
A luminaire includes a primary HID light source housing having at least one selectively powerable HID lamp and an LED arm assembly having a secondary LED light source. In some embodiments the LED arm assembly may extend between a support structure and the HID light source housing and in other embodiments the LED arm assembly may be a stand alone assembly and extend from a support structure remote from the HID light source housing. The HID lamp may be powered during user selected peak hours and the LED light source may be powered during user selected non-peak hours.
Claims20
An outdoor luminaire installable to upwardly extending support structure, the luminaire comprising:
- a LED arm assembly extending from the support structure;
- a primary HID light source housing coupled to said LED arm assembly, said primary light source housing having a downwardly facing light exit aperture;
- at least one selectively powerable HID lamp enclosed in said primary HID light source housing and electrically connected to a HID ballast;
- a selectively powerable secondary LED light source coupled to said LED arm assembly between said pole and said primary light source housing, said secondary LED light source having a plurality of LEDs selectively producing a downwardly directed light output;
- a first and a second mutually independent power supply, said first power supply in electrical connection with said HID lamp, said second power supply in electrical connection with said secondary LED light source.
An outdoor luminaire installable to a support structure, the luminaire comprising:
- a primary light source housing coupled to the support structure, said primary light source housing having a downwardly facing light exit aperture and a downwardly facing reflector;
- at least one selectively powerable HID lamp enclosed in said primary light source housing and electrically connected to an HID ballast, said HID lamp selectively producing a downwardly directed HID light output;
- a longitudinally extending LED arm assembly extending from the support structure, said LED arm assembly having a downwardly facing bottom surface;
- a selectively powerable secondary LED light source coupled to said bottom surface of said LED arm assembly and having a plurality of LEDs electrically connected to at least one driver and selectively producing a downwardly directed LED light output;
- wherein the luminosity of said HID light output is at least two times greater than the luminosity of said LED light output;
- and
- wherein said HID ballast powers said HID lamp during user selected peak hours;
- and
- wherein said at least one driver powers said secondary LED light source during user selected non-peak hours and mutually exclusive of said HID ballast powering said HID lamp.
An outdoor luminaire installable on a pole, the luminaire comprising:
- a primary light source support arm extending from the pole;
- a primary light source housing coupled to the support arm, said primary light source housing having a downwardly facing light exit aperture and a downwardly facing reflector;
- at least one selectively powerable HID lamp enclosed in said primary light source housing and electrically connected to an HID ballast, said HID lamp selectively producing a downwardly directed HID light output;
- a longitudinally extending stand alone LED arm assembly extending from the support surface, said LED arm assembly having a longitudinally extending heatsink with a downwardly facing contact surface;
- a selectively powerable secondary LED light source coupled to said contact surface of said heatsink and having a plurality of LEDs electrically connected to at least one driver enclosed in said LED arm assembly, said LED light source selectively producing a downwardly directed LED light output;
- wherein the luminosity of said HID light output is at least three times greater than the luminosity of said LED light output;
- wherein said HID light source consumes at least two times as much power as said LED light source;
- and
- wherein said HID ballast powers said HID lamp during user selected peak hours and does not power said HID lamp during user selected non-peak hours, and wherein said at least one driver powers said secondary LED light source during said non-peak hours and does not power said secondary LED light source during said peak hours.
