  • Publication number: 20130037838
    Abstract: Light-emitting elements such as LEDs are associated with light-converting material such as phosphor and/or other material. A donor substrate comprising the light-converting and/or other material is suitably placed relative to a target substrate associated with the light-emitting elements. A laser or other energy source is then used to transfer the light-converting and/or other material in a pattern via writing or masking from the donor substrate to the target substrate in accordance with the pattern. Addressability and targetability of the transfer process facilitates precise patterning of the target substrate.

  • Publication number: 20130039050
    Abstract: In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.

  • Patent number: 8334152
    Abstract: Semiconductor material is formed on a host substrate of a material exhibiting optical transparency with an intervening radiation lift off layer. A transfer device, intermediate substrate or target substrate is brought into adhesive contact with the semiconductor material and the radiation lift off layer is irradiated to weaken it, allowing the semiconductor material to be transferred off the host substrate. Electronic devices may be formed in the semiconductor layer while it is attached to the host substrate or the intermediate substrate.

  • Patent number: 8159150
    Abstract: The present invention provides a method and apparatus for optical feedback control for an illumination device, wherein the control signal for each array of one or more light-emitting elements corresponding to a particular color, is independently configured using a modification signal whose frequency is different for each color. Electronic filters whose center frequencies are substantially equal to the modification signal frequencies of the drive currents for the light-emitting elements are used to discriminate between the radiant flux corresponding to each of the different colors of light-emitting elements, from a sample of the mixed radiant flux output collected by one or more optical sensors. The output of an individual electronic filter is substantially directly proportional to the radiant flux output of the light-emitting elements of the associated color, which together with the desired luminous flux and chromaticity of the output light, the controller can use to adjust the control signals.

  • Patent number: 7909496
    Abstract: The present invention combines point light sources in combination with a light guide element and light redirecting elements into a system which can emit light across one or more extended surfaces of the light guide and may be designed to be able to emit light uniformly across the extended surfaces. The system comprises one or more light-emitting elements and a light guide in which are defined one or more voids. The light-emitting elements are optically coupled to the light guide by positioning them adjacent to a surface of the light guide, or by positioning them proximal to one or more of the voids. One or more light-emitting elements can be optically coupled to one void such that they emit light into the light guide substantially through that void and not through any other void of the one or more voids.

  • Patent number: 7906794
    Abstract: The present invention provides a lighting device package with one or more light-emitting elements operatively coupled to a substrate and a frame disposed at least in part around the one or more light-emitting elements. The frame and substrate define a cavity in which the one or more light-emitting elements are positioned, wherein this cavity can be substantially enclosed by an optically transmissive system. At least a portion of the cavity can be filled with an encapsulation material. The frame defines one or more passageways, wherein each passageway interconnects the cavity with the outside through an outside port. For example, the outside port can be accessible from the ambient when the lighting device package is in an assembled state, thereby enabling fluidic movement of the encapsulation material into and/or out of the cavity.

  • Patent number: 7868562
    Abstract: The present invention provides a system and method for controlling one or more light-emitting elements which are driven by forward currents to generate mixed light for use, for example, through a luminaire. The system has one or more light sensors for acquiring feedback optical sensor data and a user interface for providing reference data representative of a desired mixed light. The system also has a controller for transforming either the sensor data or the reference data into the coordinate space of the other and to determine a difference between the sensor and the reference data in that coordinate space. The controller is configured to adjust the forward currents during operating conditions so that the sensor data matches the setpoint data. The present invention also provides a system and method that can at least partially compensate certain temperature induced effects when transforming the optical sensor or the reference data.
