Abstract: In one aspect, optical elements and luminaires employing optical elements are described herein. In some embodiments, an optical element comprises a planar light transmissive body comprising a light input surface and a light output surface opposite the input surface, and light redirection features arranged over the light input surface and the light output surface, the light redirection features comprising refractive facets, reflective facets, facets supporting total internal reflection within the planar light transmissive body, or combinations thereof.

Abstract: A lens for chromatic aberration compensation is provided. The lens includes a lens body and a plurality of color filter films. The lens body has a light incident plane, a light exit plane and an optical axis. The light incident plane and/or the light exit plane comprises a plurality of discrete area, wherein the area comprises, for example but not limited to, a plurality of annular areas, fan-shaped areas, or polygon areas. The color filter films are disposed over the areas of the lens body respectively, and comprise red color filter films, green color filter films or blue color filter films. Accordingly, the lens for chromatic aberration compensation of the invention can eliminate the aberration effectively.

Abstract: A light emitting device having a circuit protection unit is provided. The circuit protection unit has a low-resistance layer and a potential barrier layer, wherein a barrier potential exists at the interface between the low-resistance layer and the potential barrier layer. The circuit protection unit is electrically connected with the light emitting device. When an electrostatic discharge or excessive forward current is occurred in the light emitting device, the circuit protection unit provides a rectifying function for preventing damages caused by static electricity or excessive forward current to the light emitting device.

Abstract: A dynamic workload management system enables system administrators to easily identify installed applications and to assign them to affinity groupings in order of importance to the enterprise and to enable the system administrators to save and restore multiple configurations. The workload configuration is continually updated based on the hardware utilization measurements of the application groups that make up a workload configuration. The software interface of the system of the invention permits the system to dynamically add and remove processors to and from affinity masks that are automatically set up. This feature of the invention allows the application groups to consume CPU resources according to their priority.
