Protective cover for a lighting device
First Claim
1. A lighting device for illuminating a work area, the device comprising light transmitting means for propagating light from an associated light source, cover means for allowing light to propagate through the light transmitting means with minimal disturbance to internal reflection of the light traveling therethrough, an air interface between the cover means and the light transmitting means, and attachment means for attaching an associated device to said lighting device, said attachment means including at least one of:
- an adhesive member, a Velcro fastener, clips, hooks, tabs, clamps, and snaps.

Abstract
A protective cover for protecting a lighting device from direct contact with contaminants or components which may interfere with proper operation thereof. The contaminant (e.g., blood, body tissue, dirt, oil, grease, paint, etc.) or other component (e.g., adhesive pad) can interfere with the desired internal reflection of the light propogating through a light transmitting member, by changing the angle of reflection of the propagating light. The result is that optical energy is absorbed by the contaminant or component and converted to heat, thus causing the contaminant or component to quickly rise to an undesirable temperature. The present invention protects a lighting device from such interference, while maintaining its versatility.

18. A lighting device for illuminating a work area, the device comprising light transmitting means for propagating light from an associated light source, cover means for allowing light to propagate through the light transmitting means with minimal disturbance to internal reflection of the light traveling therethrough, and an air interface between the cover means and the light transmitting means, said cover means including a central body portion, a closed end at one end of said central body portion, and an open end at the other end of said central body portion, said closed end including a lens member for focusing light emitted from said light transmitting means.
- 19. A lighting device for illuminating a work area, the device comprising light transmitting means for propagating light from an associated light source, cover means for allowing light to propagate through the light transmitting means with minimal disturbance to internal reflection of the light traveling therethrough, and an air interface between the cover means and the light transmitting means, said cover means including a central body portion, a closed end at one end of said central body portion, and an open end at the other end of said central body portion, said open end being dimensioned to interface with a connector means for sealing the open end of said cover means.

37. A boundary layer for covering a light transmitting means of a lighting device, said boundary layer allowing light to propagate through the light transmitting means without disturbance to internal reflection of light traveling therethrough, said boundary layer comprising a central body portion, a closed end at one end of said central body portion, and an open end at the other end of said central body portion, said closed end including a lens member for focusing light emitted from said light transmitting means.
- 38. A boundary layer for covering a light transmitting means of a lighting device, said boundary layer allowing light to propagate through the light transmitting means without disturbance to internal reflection of light traveling therethrough, said boundary layer comprising a central body portion, a closed end at one end of said central body portion, and an open end at the other end of said central body portion, said open end being dimensioned to interface with a connector means for sealing the open end of said boundary layer.
