Abstract: Disclosed herein are electronic devices having flat lenses. The flat lens may be combined with an infrared (IR) emitter, an IR sensor, or an image sensor, and/or one or more additional optical lenses or filters. The flat lens may provide a more compact footprint over a conventional curved optical lens. Additionally, the flat lens may be configured to bend light instantaneously, rather than gradually as the light passes through the lens. This may be advantageous in reducing the number of optical lenses within the electronic device and/or size (e.g., thickness) of the overall lens arrangement (as well as the size of the overall electronic device), therein allowing for a more compact configuration for the electronic device.

Abstract: A wavelength-converting structure for a light module including a solid-state light source. The wavelength-converting structure includes a plurality of apertures formed therein. The plurality of apertures may be configured to increase conversion efficiency of the wavelength-converting structure or color uniformity.

Abstract: A wavelength-converting structure for a light module including a solid-state light source. The wavelength-converting structure includes a pattern of discrete wavelength-converting sections of wavelength-converting material formed therein, wherein each wavelength-converting section is separated from adjacent wavelength-converting sections by at least one transmissive section. The wavelength-converting sections are comprised of a wavelength-converting material such as a phosphor that converts at least a portion of the light emitted by the solid-state light source into light having a different peak wavelength.
