The cover includes an infrared filter for substantially preventing emission of infrared light from the fluorescent lighting fixture and a protective layer for preventing damage to the infrared filter.
Claims11
A device for filtering light emitted from at least one fluorescent light emitter of a type having at least one electrical contact associated therewith, the device comprising:
- a transparent sleeve adapted to receive the at least one fluorescent light emitter, the sleeve comprising:
- at least one cap disposed on an end of the sleeve, the at least one cap having at least one hole disposed thereon, the at least one hole adapted to receive the at least one electrical contact of the at least one fluorescent light emitter;
- a filter, the filter comprising the following distinct layers of material:
- an infrared filter layer for substantially preventing emission of infrared light from the device, wherein the infrared filter layer comprises opposing sides;
- a color filter layer for filtering a color of light from the device;
- a plurality of protective layers for preventing damage to the infrared filter layer;
- and
- wherein the infrared filter layer is located between the plurality of protective layers.
