Indicator test switch for downlight lighting device and bracket therefor
View Patent ↗A lighting device including a test device for testing the proper operation of a primary and a secondary power supply alternatively providing electrical power to the light. The test device is attached to a bracket using a single fastener such as a nut and the bracket is attached to a receptacle for the light using a different single fastener, such as a pop-rivet or screw.
1. A lighting device comprising:
a socket operable to electrically connect an illuminating device to a primary power source;
a test device operable to electrically disconnect the primary power source from the illuminating device and electrically connect a secondary power source to the illuminating device; and
a bracket operable to support said test device wherein said bracket is attached to said socket at an inside surface of said socket.
2. The lighting device claimed in claim 1 , wherein said bracket is attached to said socket with a single fastening device.
3. The lighting device claimed in claim 1 , wherein the illuminating device is a fluorescent lamp.
4. The lighting device claimed in claim 1 , further comprising an indicator operable to indicate whether the secondary power source is functioning during a time when the secondary power source is not providing power to the illuminating device.
5. The lighting device claimed in claim 1 , wherein the primary power source is an AC ballast and the secondary power source is a battery.
6. The lighting device claimed in claim 2 , wherein said single fastening device is one of a pop-rivet and a screw.
7. The lighting device claimed in claim 2 , wherein said test device is attached to said bracket using a threaded nut.
8. A lighting system comprising:
a receptacle device e to receive a fluorescent lamp;
a primary power supply operable to provide electrical power to said receptacle device;
a secondary power supply operable to provide electrical power to said receptacle device;
a bracket attached to an inside surface of said receptacle device; and
a test device attached to said bracket,
wherein said bracket and said test device are both located inside an outermost dimension of said receptacle device.
9. The lighting device claimed in claim 8 , wherein said test device is electrically connected to both of said primary and secondary power supplies and is operable to selectively electrically connect said primary power supply or said secondary power supply to said receptacle device.
10. The lighting device claimed in claim 8 , further comprising at least one U-shaped fluorescent lamp electrically connected to said receptacle device.
11. The lighting device claimed in claim 10 , further comprising a reflector device detachably connected to said receptacle device and operable to reflect light downwardly from said at least one U-shaped fluorescent lamp.
12. The lighting device claimed in claim 8 , wherein said bracket is mechanically attached to said receptacle device using a single fastening device.
13. The lighting device claimed in claim 12 , wherein said test device is mechanically attached to said bracket at an end of said bracket distal from an end of said bracket attached to said receptacle device.
14. The lighting device claimed in claim 11 , wherein said bracket and said test device are disposed between said at least one U-shaped fluorescent lamp and said reflector device.
15. The lighting device claimed in claim 14 , wherein said bracket and said test device are substantially enclosed within a space created by the inner surface of said receptacle device and said reflector device.
16. The lighting device claimed in claim 9 , wherein said test device comprises an indicator device operable to indicate whether said secondary power supply is electrically connected to a main power supply, said main power supply being operable to provide electrical current to both said primary power supply and said secondary power supply.
17. The lighting device claimed in claim 16 , wherein said secondary power supply includes a battery and the indicator of said test device is operable to indicate whether the battery is charging.
