摘要： A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

摘要： In a single lighting device including a large number of light-emitting elements (LEEs), the LEEs are divided into separately powered groups, and different combinations of the groups are fully energized to achieve the desired overall brightness. In some embodiments, the number of LEEs in each group has a binary relationship to the other groups. The resolution of the dimming is the brightness of the smallest group. In one example of five binary weighted groups of LEEs, 32 brightness levels can be achieved while the LEEs in the energized groups are fully ON. Thus, since there is no high frequency switching, there is substantially no power dissipation by the dimming control system, and there is limited noise or EMI created. The dimming control can be easily implemented with a logic circuit controlling a transistor switch for each group.
摘要翻译：在包括大量发光元件（LEE）的单个照明装置中，LEE被分成单独供电的组，并且组的不同组合被完全通电以实现期望的整体亮度。在一些实施例中，每个组中的LEE的数量与其他组具有二进制关系。调光的分辨率是最小组的亮度。在LEE的五个二进制加权组的一个示例中，可以实现32个亮度级，而通电组中的LEE完全ON。因此，由于没有高频切换，所以通过调光控制系统基本上没有功率消耗，并且产生有限的噪声或EMI。可以通过控制每组的晶体管开关的逻辑电路来容易地实现调光控制。
