摘要： A luminaire can comprise a system that automatically adjusts light output from the luminaire to control light level in an illuminated area. The system can increase light output if the light level in the area falls below a target light level or decrease light output if the light level in the area rises above the target. For example, when the area is illuminated by a combination of sunlight and luminaire light, the light level can be maintained at the target level by gradually decreasing light output as the sunlight contribution increases in the morning and by gradually increasing light output as the sunlight contribution decreases in the evening. The system adjustments can take into consideration whether the light level is offset from the target due to a change in the target or a short-term fluctuation that may be due to a cloud temporarily blocking the sun.
摘要翻译： 照明器可以包括自动调节来自照明器的光输出以控制照明区域中的光级的系统。 如果该区域的光线水平降低到目标光照水平以下，则系统可以增加光输出，或者如果该区域中的光线水平升高到目标值以上，则可以减少光输出。 例如，当通过太阳光和照明灯的组合来照亮该区域时，通过逐渐降低光输出，当阳光的贡献在早晨增加时，并且通过逐渐增加光输出作为阳光的贡献，能够将光水平维持在目标水平 晚上减少 系统调整可以考虑到由于目标的变化而导致的光水平是否偏离目标，或者由于云暂时阻挡太阳而引起的短期波动。

摘要： The present disclosure provides techniques for a power factor correction system having an arbitrary input waveform. The present disclosure provides two example methods of digital power factor correction that allow for a high power factor on an arbitrary input waveform. The two example methods are applicable to both constant-current inputs and constant-voltage inputs. One example method samples the arbitrary input waveform to produce a reference table used to synchronize the input voltage with the input current in a constant current system, and to synchronize the input current to the input voltage in a constant voltage system. A second example method uses instantaneous input values as a reference in performing power factor correction.

摘要： A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises a cavity. At least a portion of the cavity can have an outline that is egg-shaped in cross section. A backside of the cavity (or a backside portion of the optic) can have an irregular shape for receiving the light emitting diode, for example to form a receptacle shaped to fit a circuit board on which the light emitting diode is mounted.

摘要： Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.
