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.

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: An SMD includes a substrate and one or more electrical contacts on a first surface of the substrate. Each one of the electrical contacts are configured to couple to a corresponding electrical contact located on a surface of a carrier, and are located within a concentric area of the first surface that is less than about 50% of a total area of the first surface. By providing the electrical contacts within the concentric area, the mechanical stress experienced by the electrical contacts can be significantly reduced when compared to conventional SMDs including electrical contacts on the outer edges thereof. Accordingly, the failure rate of the SMD due to separation of one or more of the electrical contacts from the carrier may be reduced.
Abstract translation: SMD包括衬底和在衬底的第一表面上的一个或多个电触点。 电触头中的每一个被配置为耦合到位于载体表面上的对应的电触点，并且位于第一表面的同心区域内，小于第一表面的总面积的约50％。 通过在同心区域内设置电触头，与传统的包括其外边缘上的电触点的SMD相比，可以显着降低由电触点所经历的机械应力。 因此，可以减少由于一个或多个电触点与载体分离导致的SMD的故障率。
