Abstract

A lighting system for illuminating artwork includes a housing; a lamp mounted within said housing and including a halogen bulb and a reflector, said reflector having a dichroic coating; a linear spread lens positioned in front of said lamp and having an etched portion covering less than one hundred percent of a first surface of said lens; and a door associated with said housing and defining an opening therein, said opening having a flattened portion and a rounded portion, said linear spread lens positioned over said opening, and the light emitted by the lighting system being directed through said linear spread lens and said opening. The resulting lighting system produces safe light diffused evenly substantially over the entire surface of a piece of artwork.

Claims (26)

1. A lighting system for illuminating artwork, comprising:

a housing;

a lamp mounted within said housing and including a halogen bulb and a reflector, said reflector having a dichroic coating;

a linear spread lens positioned in front of said lamp and having an etched portion on a first surface of said lens; and

a door associated with said housing and defining an opening in said door, said opening having a flattened portion and a rounded portion, said linear spread lens positioned over said opening, and the light emitted by the lighting system being directed through said linear spread lens and said opening.

2. A lighting system for illuminating artwork as set forth in claim 1 , wherein said opening is approximately D-shaped.

3. A lighting system for illuminating artwork as set forth in claim 1 , wherein said flattened portion of said opening is closer to the illuminated artwork than said rounded portion.

4. A lighting system for illuminating artwork, comprising:

a housing;

a lamp mounted within said housing and including a halogen bulb and a reflector, said reflector having a dichroic coating;

a linear spread lens positioned in front of said lamp and having an etched portion on a first surface of said lens; and

a door associated with said housing and directing the light emitted by the lighting system through said linear spread lens.

5. A lighting system for illuminating artwork as set forth in claim 4 , wherein said etched portion covers all of said first surface of said linear spread lens.

6. A lighting system for illuminating artwork as set forth in claim 4 , wherein said etched portion covers approximately fifty percent of said first surface of said linear spread lens.

7. A lighting system for illuminating artwork as set forth in claim 4 , wherein said etched portion covers between approximately seventy-five percent and approximately twenty-five percent of said first surface of said linear spread lens.

8. A lighting system for illuminating artwork as set forth in claim 4 , wherein said etched portion covers less than approximately twenty-five percent of said first surface of said linear spread lens.

9. An optical conversion system for an artwork light having a halogen light source, including:

a reflector having a dichroic coating surrounding the halogen light source; and

a linear spread lens positioned in front of the halogen light source, said linear spread lens having:

an ultraviolet filter coating;

a color-adjusting tint; and

an etched portion on a first surface of said lens.

10. An optical conversion system for illuminating artwork as set forth in claim 9 , wherein said etched portion covers all of said first surface of said linear spread lens.

11. An optical conversion system for an artwork light as set forth in claim 9 , wherein said etched portion covers approximately fifty percent of said first surface of said linear spread lens.

12. An optical conversion system for illuminating artwork as set forth in claim 9 , wherein said etched portion covers between approximately seventy-five percent and approximately twenty-five percent of said first surface of said linear spread lens.

13. An optical conversion system for illuminating artwork as set forth in claim 9 , wherein said etched portion covers less than approximately twenty-five percent of said first surface of said linear spread lens.
