照明具
Document Type and Number:
Japanese Patent JP7090630
Kind Code:
B2
Abstract:
Asymmetrical lenses are provided having design to mitigate or eliminate field of view mismatch between image sensor modules and luminaires incorporating the image sensor modules. Briefly, an asymmetrical lens comprises an optical axis and a front surface comprising a first set of normal axes (x, y) in a plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x, y). The asymmetrical lens also comprises a back surface comprising a second set of normal axes (x′, y′) in the plane normal to the optical axis and a negative radius of curvature or positive radius of curvature along each of the normal axes (x′, y′), wherein the asymmetrical lens has negative refractive power or positive refractive power in each of an x-axis and y-axis of an image plane of the asymmetrical lens.
