Abstract: A light pipe such as a fiber ribbon may be formed from fibers joined by binder such as extruded binder. The fiber ribbon or other light pipe may have bends. A light source may provide light to an input of a fiber ribbon that is guided by the fiber ribbon to a corresponding output. The output may be located in an interior portion of an electronic device or may be positioned so that light from the output exits the electronic device and illuminates external objects. The light source may have light-emitting devices on a substrate. The light-emitting devices may be vertical cavity surface-emitting laser diodes or other lasers and/or may be light-emitting diodes. Light-emitting devices may be arranged in discrete clusters corresponding to the locations of fiber cores in the fiber ribbon.

Abstract: An optical module (20) includes a transparent substrate (30) and a refractive optical element (42) mounted on the substrate. A conductive heating trace (60) is deposited on the substrate around the refractive optical element. A temperature sensor (62) senses a temperature of the substrate. Control circuitry (50, 51, 53) is coupled to the temperature sensor so as to measure a difference between the temperature of the substrate and a target operating temperature of the module, and to drive a current through the conductive heating trace, responsively to the difference, so as to heat the substrate to the target operating temperature.
