Abstract: The present disclosure relates to shifting a chromaticity of light generated from a light-emitting device. A light-emitting device may incorporate an optical element (e.g., filter) so that light emitted from a light-generating surface having an initial chromaticity may be altered. The optical element may shift the chromaticity of emitted light having the initial chromaticity to a final chromaticity that is different from the initial chromaticity. Thus, the chromaticity of emitted light from the manufactured LEDs that would otherwise be unacceptable for having chromaticity coordinates that fall outside of a desired chromaticity bin is shifted so as to have chromaticity coordinates that fall within suitable parameters. Accordingly, a number of the manufactured LEDs that would normally be discarded may be salvaged.
Abstract: A slim LED package configured to handle large current, having a narrow width, an LED chip mounting area positioned centro-symmetrically within the package, mounting holes positioned equidistantly from the mounting area, wherein multiple packages may be arranged with alternating anode and cathode ends in such a manner that a high-power density radiometric flux line may be created. Some embodiments include current density management areas positioned on one more sides of the LED chip mounting area.

Abstract: The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.
