    Abstract: Solid state lighting components are provided with improved color rendering, improved color uniformity, and improved directional lighting, and that are suitable for use in high output lighting applications and can be used in place of CDMH bulb lighting. Exemplary solid state lighting components include a substrate comprising a light emitter surface and or more light emitters disposed on and/or over the light emitter surface. Exemplary components include a light directing optic and/or a diffusing optic for mixing light. The light directing optic may be disposed at least partially around a perimeter of the light emitter surface. The diffusing optic may be disposed between portions of the light directing optic and spaced apart from the light emitter surface.

    Abstract: A solid state lighting apparatus can include a plurality of light-emitting devices (LEDs) that are electrically coupled together in at least one string. The apparatus can further include a first LED segment that is configured to emit a first chromaticity light coupled across a first bypass circuit, a second LED segment that is configured to emit a second chromaticity light coupled across a second bypass circuit, and at least one additional LED segment that is configured to emit an additional chromaticity light coupled across a respective at least one additional bypass circuit. A control circuit can be configured to modulate the at least one additional bypass circuit, to cause the lighting apparatus to emit an additional v′ shift in a chromaticity value of light emitted by the string to vary substantially in conformance with a Planckian locus in response to a dimming input to the control circuit.

    Abstract: A plurality of light-emitting devices (LEDs), included in at least a string, can include at least one first LED configured to emit first chromaticity light, at least one second LED configured to emit second chromaticity light, and at least one additional LED configured to emit additional chromaticity light, wherein the at least one string can be operated by modulating the first modulated LED segment and/or the at least one additional modulated LED segment based on respective specified chromaticity values of the plurality of LEDs to provide the light substantially in conformance with a Planckian locus. The chromaticity of the light emitted by the at least one string can b e measured to provide a measured chromaticity value and the modulation of the first modulated LED segment or the at least one additional modulated LED segment can be adjusted by a shift value based on a difference between the measured chromaticity value and a specified chromaticity value to provide an additional v′ shift in light toward the Planckian locus.
