Publication number: 20230417382Abstract: Lighting devices having optical waveguides for controlled light distribution are provided. A lighting device includes a housing, a light emitter disposed in the housing, and a waveguide at least partially disposed in an opening of the housing. The waveguide includes a light input surface defining coupling features, wherein the light emitter is disposed adjacent the light input surface and emits light into the coupling features. The waveguide further includes a light transmission portion disposed between the light input surface and a light extraction portion, wherein light from the light emitter received at the light input surface propagates through the light transmission portion toward the light extraction portion. The waveguide further includes the light extraction portion, which comprises at least one light redirection feature and at least one light extraction feature that cooperate to generate a controlled light pattern exiting the lighting device.Type: ApplicationFiled: April 17, 2023Publication date: December 28, 2023Inventors: Kurt Wilcox, Jin Hong Lim, Curt Progl, Steve Wilcenski, Zongjie Yuan

Patent number: 10502935Abstract: 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.Type: GrantFiled: March 3, 2017Date of Patent: December 10, 2019Assignee: IDEAL INDUSTRIES LIGHTING LLCInventors: Jin Hong Lim, John Roberts, Steve Wilcenski
