  • Publication number: 20210173138
    Abstract: An illumination device includes a plurality of light-emitting elements (LEEs); a light guide extending in a forward direction from a first end to a second end to receive at the first end light emitted by the LEEs and to guide the received light to the second end; an optical extractor optically coupled to the second end to receive the guided light, the optical extractor including a redirecting surface to reflect a first portion of the guided light, the reflected light being output by the optical extractor in a backward angular range, and the redirecting surface having one or more transmissive portions to transmit a second portion of the guided light in the forward direction; and one or more optical elements optically coupled to the transmissive portions, the optical elements to modify the light transmitted through the transmissive portions and to output the modified light in a forward angular range.

  • Publication number: 20210148517
    Abstract: In one embodiment, an LED lamp has a generally bulb shape. The LEDs are low power types and are encapsulated in thin, narrow, flexible strips. The LEDs are connected in series in the strips to drop a desired voltage. The strips are affixed to the outer surface of a bulb form to provide structure to the lamp. The strips are connected in parallel to a power supply, which may be housed in the lamp. Since many low power LEDs are used and are spread out over a large surface area, there is no need for a large metal heat sink. Further, the light emission is similar to that of an incandescent bulb. In other embodiment, there is no bulb form and the strips are bendable to have a variety of shapes. In another embodiment, a light sheet is bent to provide 360 degrees of light emission. Many other embodiments are described.

  • Patent number: 10859758
    Abstract: 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.
