Claims
- 1. A luminaire, comprising:a housing; a lamp with optical sides mounted in said housing; a main reflector mounted in said housing about said lamp, said main reflector having a plurality of openings; and a first removable reflector shield having a body portion and a plurality of tabs extending from said body portion, said tabs being releasably engaged in said openings.
- 2. The luminaire of claim 1, further comprising:a second removable reflector shield having a body portion and a plurality of tabs extending from said body portion, said tabs are releasably engaged in said openings.
- 3. The luminaire of claim 1 whereinsaid first reflector shield has first, second and third tabs, said first and third tabs being substantially L-shaped, said second tab being substantially T-shaped.
- 4. The luminaire of claim 1 whereinsaid openings are substantially semi-circular for receiving said plurality of tabs.
- 5. The luminaire of claim 1 whereinsaid first reflector shield is made of a flexible material for adapting to a curve defined by said openings.
- 6. The luminaire of claim 5 whereinsaid curve is substantially parabolic.
- 7. The luminaire of claim 1 whereinsaid first reflector shield covers at least half of said optical sides of said lamp.
- 8. The luminaire of claim 1 whereinsaid first reflector shield is made of specular aluminum.
- 9. The luminaire of claim 1 whereinsaid first reflector shield and said plurality of tabs are unitarily formed.
- 10. A luminaire, comprising:a housing; a lamp with optical sides mounted in said housing; a main reflector mounted in said housing about said lamp, said main reflector having four openings, said openings being substantially semi-circular and located 90 degrees apart; a first removable reflector shield having a body portion and first, second and third tabs extending from said body portion thereof, said first, second and third tabs being releasably engaged in three of said openings, said first and third tabs being substantially L-shaped, said second tab being substantially T-shaped and being spaced between said first and third tabs; and a second removable reflector shield having a body portion and fourth, fifth and sixth tabs extending from said body portion thereof, said fourth, fifth and sixth tabs being releasably engaged in three of said openings, said fourth and sixth tabs being substantially L-shaped, and said fifth tab being substantially T-shaped and being spaced between said fourth and sixth tabs.
- 11. The luminaire of claim 10 whereineach of said reflector shields is made of a flexible material for adapting to a curve defined by said openings.
- 12. The luminaire of claim 11 whereinsaid curve is substantially parabolic.
- 13. The luminaire of claim 1 whereineach of said reflector shields covers at least half of said optical sides of said lamp.
- 14. The luminaire of claim 1 whereineach of said reflector shields is made of specular aluminum.
- 15. The luminaire of claim 1 whereineach of said reflector shields and said tabs thereof are unitarily formed.
- 16. A method of blocking and redirecting light from a luminaire, comprising the steps of:bending a first reflector shield to a shape defined by a plurality of openings in a luminaire reflector mounted in a luminaire; and releasably attaching said first shield to the luminaire reflector by inserting a plurality of tabs on the first shield in the plurality of openings in the luminaire reflector for blocking and redirecting light emitted by a lamp mounted in the luminaire, the lamp having optical sides, and said first shield covering substantially half of the optical sides of the lamp; whereby a first beam configuration is created.
- 17. The method of claim 16, further comprising the steps of:bending a second reflector shield to the shape defined by the plurality of openings in the luminaire reflector mounted in the luminaire; and releasably attaching said second shield to the luminaire reflector by inserting a plurality of tabs on said second shield in the plurality of openings in the luminaire reflector for further blocking and redirecting light emitted by the lamp mounted in the luminaire, said second shield covering substantially half of the optical sides of the lamp; whereby a second beam configuration is created.
- 18. The method of claim 17 whereinsaid first and second reflector shields are attached on opposite sides of the reflector for completely enclosing the optical sides of the lamp, thereby cutting off 360 degrees of light emitted by the lamp and resulting in a spotlight beam being emitted from the luminaire.
- 19. The method of claim 17 whereinsaid first and second reflector shields are attached on the luminaire reflector such that substantially 90 degrees of said first and second shields overlap, thereby cutting off substantially 270 degrees of light emitted by the lamp.
- 20. The method of claim 17, further comprising:removing said second reflector shield; and reattaching said second shield to the luminaire reflector in a different position by inserting said plurality of tabs on said second shield in the plurality of openings in the luminaire reflector for altering the second beam configuration.
