Abstract

A system for illuminating an object comprises a plurality of light beams; an emission region from which the plurality of light beams is emitted; and an illumination zone defined by placement of the light beams and being projected in a manner to maximize illumination of the object. A method for illuminating an object using a system comprising one or more light sources comprises generating a plurality of light beams; placing the light beams to define an illumination zone; and positioning the system such that the object falls within the illumination zone. A system for illuminating an object comprises a body having one or more openings in an outer surface; one or more light sources configured to generate a plurality of light beams; and a rotation mechanism configured to rotate the plurality of light beams to form a contiguous effective illumination zone configured to illuminate an object disposed anywhere therein.

Claims

1. A device for illuminating an object, the device comprising:

a light source to generate a light beam having a substantially solid fan shape;

a housing having an outer wall, a base, and one or more openings on the outer wall through which the solid fan-shaped light beam can be emitted;

a support positioned in the housing for supporting the light source to permit the solid fan-shaped light beam to be emitted through the opening in the outer wall of the housing at a slanted orientation relative to the housing, and illuminate the object, including both a raised portion of the object and a portion of the object adjacent to a surface on which the object is located; and

a motorized rotation mechanism situated within the housing to rotate the slanted light beam about an axis of the housing by rotating the support relative to the base to sweep an illumination zone defined by the slanted light beam about a circumference of the housing.

2. A device as set forth in claim 1, the motorized rotation mechanism including a bearing rotably coupling the base and the support to permit rotation of the support relative to the base.

3. A device as set forth in claim 1, wherein the housing has a shape of a dustpan.

4. A device as set forth in claim 1, further comprising additional light sources within the housing operable to generate additional light beams.

5. A device as set forth in claim 1, wherein the solid fan-shaped light beam has an elongated cross section that is line-shaped.

6. A device as set forth in claim 1, wherein the support includes an arm and a fiber optic cable or other optical conduit.

7. A method for illuminating an object, the method comprising:

positioning, on a surface, a device, the device including a housing having an outer wall, a base, and one or more openings on the outer wall,

supporting, by a support positioned within the housing, a light source for generating a substantially solid fan-shaped light beam;

emitting, through the opening on the outer wall of the housing, the solid fan-shaped light beam at a slanted orientation relative to the housing to illuminate the object, including both a raised portion of the object and a portion of the object adjacent to a surface on which the object is located; and

rotating, by a motorized rotation mechanism situated within the housing, the slanted light beam about an axis of the housing by rotating the support relative to the base to sweep an illumination zone defined by the slanted light beam about a circumference of the housing.

8. A method as set forth in claim 7, wherein in the step of emitting, the solid fan-shaped light beam has an elongated cross section that is line-shaped.

9. A method as set forth in claim 7, wherein the axis of the housing is a vertical axis of the housing.

10. A method as set forth in claim 7, wherein the step of positioning comprises positioning the housing on, above, or below the surface on which the object is disposed.

11. A method as set forth in claim 7, wherein in the step of emitting, the light beam is directed at a downwards angle relative to the base.

12. A method as set forth in claim 7, wherein the step of positioning further includes directing the housing at a downwards angle relative to the surface on which the object is situated.

16. A method as set forth in claim 7, wherein the motorized rotation mechanism includes a bearing rotably coupling the base and the support to permit rotation of the support relative to the base.

13. A system for illuminating an object, the system comprising:

a housing having an outer wall, a base, and an opening in the outer wall;

a light source positioned within the housing to generate a substantially solid fan-shaped light beam emmittable through the opening in the outer wall at a slanted orientation relative to the housing to illuminate the object, including both a raised portion of the object and a portion of the object adjacent to a surface on which the object is located; and

a motorized rotation mechanism situated within the housing to rotate the slanted light beam about an axis of the housing by rotating the support relative to the base to sweep an illumination zone defined by the slanted light beam about a circumference of the housing.

14. A system as set forth in claim 13, wherein the light source is further positioned at a downward angle relative to the base.

15. A system as set forth in claim 13, further comprising additional light sources within the housing operable to generate additional light beams.

17. A system as set forth in claim 13, wherein the solid fan-shaped light beam has a substantially elongated cross section.

18. A system as set forth in claim 13, wherein the motorized rotation mechanism includes a bearing rotably coupling the base and the support to permit rotation of the support relative to the base.
