摘要： 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 is formed by pairs of transverse surfaces each surface of which redirects the received light.

摘要： A luminaire includes a first waveguide having a first primary light emitting surface directed in a first direction and a first secondary light emitting surface directed in a second direction. A second waveguide having a second primary light emitting surface directed in the second direction and a second secondary light emitting surface directed in the first direction. A first plurality of LEDs are optically coupled to the first waveguide and a second plurality of LEDs are optically coupled to the second waveguide. The first and second waveguides are independently operable. The first and second plurality of LEDs may comprise LED groups where each of the LED groups are independently controllable. The light emission pattern and light properties of the emitted light are controllable.

摘要： 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.

摘要： 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.

摘要： 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.
