An electronic device includes a substrate, a set of light emitters on the substrate and arranged in a plurality of axisymmetric light emitter groups, a set of lenses including a different lens disposed over each axisymmetric light emitter group of the plurality of axisymmetric light emitter groups, and a set of optical fibers. At least one optical fiber in the set of optical fibers has a proximal end, a distal end, and a bend between the proximal end and the distal end. The proximal end is positioned to receive light, through a respective lens in the set of lenses, from the light emitters of a respective axisymmetric light emitter group in the plurality of axisymmetric light emitter groups.

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens. In some embodiments, an optical window is disposed in the hollow chamber and is optically coupled to the output surface of the lens such that the light exiting the lens passes through the optical window before exiting the light module. In some embodiments, the shoulder can be formed as part of the housing. In other embodiments, the shoulder can be provided by a sleeve disposed in the module's housing.
