A DUSTPAN WITH AN INTEGRATED ILLUMINATION SOURCE
Abstract:
This invention describes a dustpan 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.
