Assembly and method for glare elimination
An assembly is disclosed, which comprises a light fixture comprising a light source thereon; an image capturing device mounted adjacent with the light source; and a housing covering the image capturing device, wherein the housing has a window within a field of view of the image capturing device; wherein at least a portion of the window serving as working optical surface of the image capturing device is located within a shadow of direct light from the light source of the light fixture.
1. An outdoor light fixture assembly, comprising:
a roadway light fixture comprising an LED light source thereon;
an image capturing device mounted with the assembly; and
a shield of opaque or diffusive material provided between the light source and a working optical surface of the image capturing device for creating a shadow;
the image capturing device being at least partially covered by a housing,
wherein the housing has a window within a field of view of the image capturing device, at least a portion of the window serving as the working optical surface of the image capturing device, and
wherein at least a portion of the window is located within a shadow of direct light from the light source.
2. The outdoor light fixture assembly of claim 1 , wherein the shield serves as a part of the housing.
3. The outdoor light fixture assembly of claim 2 , comprising a surface extended from the housing for shielding direct light from the light source.
4. The outdoor light fixture assembly of claim 1 , wherein the shield forms at least one of cylindrical shape, visor, or hood.
5. The outdoor light fixture assembly of claim 1 , wherein the light source comprises a reflector and a lamp within the reflector.
6. The outdoor light fixture assembly of claim 5 , wherein the reflector comprises an ellipsoidal reflector.
7. The outdoor light fixture assembly of claim 1 , wherein scattering material is provided on at least a portion of an outer surface of the housing for breaking up light from the light source.
8. The outdoor light fixture assembly of claim 7 , wherein the scattering material is selected from diffuser or light absorbent material.
9. The outdoor light fixture assembly of claim 1 , wherein the housing comprises absorptive coatings and/or non-specular finishes on at least a portion of an exterior and/or interior surface of the housing at least partially covering the image capturing device, or on interior components inside the housing.
10. The outdoor light fixture assembly of claim 1 , wherein said shield is a shield of diffusive material provided between the light source and the working optical surface of the image capturing device.
11. An outdoor light fixture assembly, comprising:
a roadway light fixture comprising an LED light source thereon;
a camera mounted with the assembly; and
a housing covering the camera, wherein the housing has a window within a field of view of the camera, the housing comprising a surface extending from the housing for shielding direct light from the light source;
wherein at least a portion of the window serving as working optical surface of the camera is located within a shadow of direct light from the light source of the light fixture.
12. The outdoor light fixture assembly of claim 11 , wherein the light source comprises a reflector and a lamp within the reflector.
13. The outdoor light fixture assembly of claim 12 , wherein the reflector comprises an ellipsoidal reflector.
14. The outdoor light fixture assembly of claim 11 , wherein scattering material is provided on the housing for breaking up light from the light source.
15. The outdoor light fixture assembly of claim 11 , wherein the housing comprises absorptive coatings and/or non-specular finishes on at least a portion of an exterior and/or interior surface of the housing at least partially covering the image capturing device, or on interior components inside the housing.
16. An outdoor light fixture assembly, comprising:
a roadway light fixture comprising an LED light source thereon;
an image capturing device mounted with the assembly; and
a shield of diffusive material provided between the light source and a working optical surface of the image capturing device;
the image capturing device being at least partially covered by a housing, wherein the housing has a window within a field of view of the image capturing device, at least a portion of the window serving as the working optical surface of the image capturing device.
