This invention describes a dust pan comprising a light source that is designed to illuminate a floor or other flat work surface in front of the dustpan for the purpose of locating and collecting small hard to see objects. This can be for the purpose of cleaning or simply locating a small valuable object. The light source is fashioned such that it provides a very low grazing angle of illumination that it skims across a surface. Small objects or particles are visible as being brighter than the surroundings and set off by a long shadow on the side of the particle away from the light.

What is claimed is: 1. An illuminated dustpan comprising a) a dustpan with a debris receptacle resting flat on a planar surface to store debris swept into the debris receptacle by a broom, b) at least one body section attached to the debris receptacle, and c) at least one light producing structure,
What is claimed is: 1. An illuminated dustpan comprising a) a dustpan with a debris receptacle resting flat on a planar surface to store debris swept into the debris receptacle by a broom, b) at least one body section attached to the debris receptacle, and c) at least one light producing structure, mounted in said at least one body section, said at least one light producing structure comprising; i) at least one light source mounted in the at least one light producing structure, ii) at least one light shaping means mounted in the at least one light producing structure for focused, low grazing angle illumination, said at least one light shaping means being capable of providing illumination of the surface in an area extending from immediately adjacent to the dustpan and for a further distance from the dustpan, wherein said illumination is characterized as having a low grazing angle, and iii) whereby said light is focused at an angle nearly parallel to the surface. 2. The illuminated dustpan of claim 1, wherein said light shaping means comprises a reflector and a lens. 3. The illuminated dustpan of claim 2, wherein the lens comprises a cylindrical lens. 4. The illuminated dustpan of claim 1, wherein said light shaping means comprises a reflector. 5. The illuminated dustpan of claim 2, wherein the lens is a fresnel lens. 6. The illuminated dustpan of claim 1, wherein the low grazing angle is less than 30 degrees. 7. The illuminated dustpan of claim 6, wherein the grazing angle is less than 10 degrees. 8. The illuminated dustpan of claim 7, wherein the grazing angle is in the range between six and zero degrees inclusive. 9. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 500 lux on the surface at a distance from less than one foot to at least 5 feet from the dustpan. 10. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 2500 lux on the surface at a distance from about one foot to at least 5 feet from the dustpan. 11. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 5000 lux on the surface at a distance from about one foot to at least 5 feet from the dustpan. 12. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 500 lux on the surface at a distance from about one foot to at least 10 feet from the dustpan. 13. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 2500 lux on the surface at a distance from less than one foot to at least 10 feet from the dustpan. 14. The illuminated dustpan of claim 6, wherein the illumination of the surface is at least 5000 lux on the surface at a distance from less than one foot to at least 10 feet from the dustpan. 15. The illuminated dustpan of claim 1, wherein said light source is positioned close enough to the surface to form a beam on the surface with low grazing angle. 16. The illuminated dustpan of claim 15, wherein said light source is in the range of about one to four inches above the planar surface when the dustpan sits on the planar surface. 17. The illuminated dustpan of claim 1, wherein said high intensity light source comprises a light chosen from the group consisting of incandescent, tungsten, krypton, xenon, LED's, LED arrays, and scanning lasers. 18. The illuminated dustpan of claim l, wherein the at least one body section comprises at least two body sections. 19. The illuminated dustpan of claim 18, wherein the at least one light producing structure, comprises at least two light producing structures. 20. An illuminated apparatus comprising a) a dustpan with a debris receptacle resting flat on a planar surface to store debris swept into the debris receptacle by a broom, b) at least one body section attached to the debris receptacle, and c) at least one light producing structure, mounted in said at least one body section, said at least one light producing structure comprising; i) at least one light source mounted in the at least one light producing structure, ii) at least one light shaper mounted in the at least one light producing structure, said at least one light shaper being capable of providing illumination of the surface in an area extending from immediately adjacent to the dustpan and for a further distance from the dustpan, wherein said illumination is characterized as having a low grazing angle, and iii) whereby said light is focused at an angle nearly parallel to the surface.
