Abstract: A LED lamp has at least two LEDs to provide light of at least two different spectral outputs. An optic element has an entry surface disposed to receive the light from the LEDs. The entry surface includes refracting surfaces that refract the light tangentially. The refracting surfaces may extend radially relative to a center of the entry surface. The refracting surfaces may be continuously curved in cross-section where the refracting surfaces may include convex refracting surfaces and concave refracting surfaces.

Abstract: A low profile lighting module. Devices according to this disclosure can produce a uniform light intensity output profile, limiting the perceived appearance of individual point sources, from direct lighting modules comprising several light emitting diodes. Individual lighting device components are disclosed that can contribute to this uniform profile, including: primary optics, secondary optics, and contoured housing elements. These components can interact with and control emitted light, thus adjusting its pattern. These components can alter the direction of emitted light, providing a more uniform light intensity over a wider range of viewing angle.

Abstract: The present disclosure is directed to LED components, and systems using such components, having a light emission profile that may be controlled independently of the lens shape by varying the position and/or orientation of LED chips with respect to one or both of an overlying lens and the surface of the component. For example, the optical centers of the LED emitting surface and the lens, which are normally aligned, may be offset from each other to generate a controlled and predictable emission profile. The LED chips may be positioned to provide a peak emission shifted from a perpendicular centerline of the lens base. The use of offset emitters allows for LED components with shifted or tilted emission patterns, without causing output at high angles of the components. This is beneficial as it allows a lighting system to have tilted emission from the LED component and primary optics.

Abstract: A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis. The lens has a faceted output region, a smooth output surface and at least one reflective surface which reflects light through total-internal-reflection (TIR) toward the faceted output region. The faceted output region is formed by pairs of transverse surfaces each surface of which redirects the received light to provide a composite illuminance pattern. The lens may further have faceted input surfaces at least partially defining a light-input cavity about the emitter axis. The faceted input region are formed by pairs of transverse surfaces each surface of which redirects the received light.

Abstract: A lighting fixture appears as a skylight and is referred to as a skylight fixture. The skylight fixture has a sky-resembling assembly and a plurality of sun-resembling assemblies. The sky-resembling assembly has a sky-resembling optical assembly and a sky-specific light source, wherein light from the sky-specific light source exits a planar interior surface of the sky-resembling light optical assembly as skylight light. The plurality of sun-resembling assemblies are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly. Each of the plurality of sun-resembling assemblies has a sun-resembling optical assembly and a sun-specific light source, wherein light from the sun-specific light source exits a planar interior surface of the sun-resembling optical assembly as sunlight light.

Abstract: LED packages are disclosed that are compact and efficiently emit light, and can comprise encapsulants with planar surfaces that refract and/or reflect light within the package encapsulant. The packages can also comprise a submount with one or more LEDs, and a blanket conversion material layer on the one or more LEDs and the submount. The encapsulant can be on the submount, over the LEDs, and light reflected within the encapsulant will reach the conversion material, where it will be absorbed and emitted omnidirectionally. This allows for reflected light to now escape from the encapsulant. This allows for efficient emission and a broader emission profile, for example when compared to conventional packages with hemispheric encapsulants or lenses. In certain embodiments, the LED package provides a higher chip area to LED package area ratio. By using an encapsulant with planar surfaces, the LED package can provide unique dimensional relationships between the various features and the LED package ratios, enabling more flexibility in using the packages in different applications.
