Infrared filter system for fluorescent lighting
An apparatus effectively filters infrared light from fluorescent lighting using a cover that is easily adapted to typical fluorescent lighting and assemblies. A cover for a fluorescent light bulb or lighting fixture operates to filter infrared light. The cover includes infrared filtration or blocking properties for substantially preventing emission of infrared light from the fluorescent light or lighting fixture. Transmission reduction may also be provided.

A cover for infrared filtration of a tubular fluorescent light bulb, comprising a cylindrical tube including an open center sized and shaped to receive the tubular fluorescent light bulb, the cylindrical tube possessing infrared blocking and transmission reduction properties which are formed directly into the tube.
2 . The cover of claim 1 wherein the transmission reduction properties are provided by green filtration.
3 . The cover of claim 1 , further including an opaque light blocker.
4 . The cover of claim 1 , wherein the infrared blocking properties which are formed directly into the tube are Night Vision Imaging Systems Green A-compatible.
5 . The cover of claim 1 , wherein the infrared blocking properties which are formed directly into the tube are Night Vision Imaging Systems Green B-compatible.
6 . The cover of claim 1 , wherein the infrared blocking properties which are formed directly into the tube are Night Vision Imaging Systems White-compatible.
7 . The cover of claim 1 , further comprising: a first cap for capping a first end of the cylindrical tube and a second cap for capping a second end of the cylindrical tube so as to retain the tubular fluorescent light bulb within the open center of the cylindrical tube.
8 . A cover for infrared filtration of a tubular fluorescent light bulb, comprising a cylindrical tube including an open center defined by a wall that is sized and shaped to receive the tubular fluorescent light bulb, the cylindrical tube possessing infrared blocking properties which are formed directly within the wall of the tube.
9 . The cover of claim 8 wherein the cylindrical tube further possesses transmission reduction properties which are formed directly within the wall of the tube.
10 . The cover of claim 9 wherein the transmission reduction properties are provided by green filtration.
11 . The cover of claim 8 , further including an opaque light blocker.
12 . The cover of claim 8 , wherein the infrared blocking properties which are formed directly within the wall of the tube are Night Vision Imaging Systems Green A-compatible.
13 . The cover of claim 8 , wherein the infrared blocking properties which are formed directly within the wall of the tube are Night Vision Imaging Systems Green B-compatible.
14 . The cover of claim 8 , wherein the infrared blocking properties which are formed directly within the wall of the tube are Night Vision Imaging Systems White-compatible.
15 . The cover of claim 8 , further comprising: a first cap for capping a first end of the cylindrical tube and a second cap for capping a second end of the cylindrical tube so as to retain the tubular fluorescent light bulb within the open center of the cylindrical tube.
16 . A cover for infrared filtration of a tubular fluorescent light bulb, comprising a cylindrical tube including an open center sized and shaped to receive the tubular fluorescent light bulb, the cylindrical tube possessing infrared blocking and transmission reduction properties which are integrated into the tube.
17 . The cover of claim 16 wherein the transmission reduction properties are provided by green filtration.
18 . The cover of claim 16 , further including an opaque light blocker.
19 . The cover of claim 16 , wherein the infrared blocking properties which are integrated into the tube are Night Vision Imaging Systems Green A-compatible.
20 . The cover of claim 16 , wherein the infrared blocking properties which are integrated into the tube are Night Vision Imaging Systems Green B-compatible.
21 . The cover of claim 16 , wherein the infrared blocking properties which are integrated into the tube are Night Vision Imaging Systems White-compatible.
22 . The cover of claim 16 , further comprising: a first cap for capping a first end of the cylindrical tube and a second cap for capping a second end of the cylindrical tube so as to retain the tubular fluorescent light bulb within the open center of the cylindrical tube.
23 . A cover for infrared filtration of a tubular fluorescent light bulb, comprising a cylindrical tube including an open center defined by a wall that is sized and shaped to receive the tubular fluorescent light bulb, the cylindrical tube possessing infrared blocking properties which are integrated within the wall of the tube.
24 . The cover of claim 23 wherein the cylindrical tube further possesses transmission reduction properties which are formed directly within the wall of the tube.
25 . The cover of claim 24 wherein the transmission reduction properties are provided by green filtration.
26 . The cover of claim 23 , further including an opaque light blocker.
27 . The cover of claim 23 , wherein the infrared blocking properties which are formed directly within the wall of the tube are Night Vision Imaging Systems Green A-compatible.
