    摘要: Segmented LED arrays with various diffusing elements are disclosed. An example segmented LED array includes a plurality of LEDs arranged in a plurality of sections where a given section may include one or more LEDs and where each section may be aligned with a different respective optical element such as a lens. Each LED may be a wavelength-converting LED in that it may include a light emitter arrangement and a wavelength-converter structure. In various embodiments, diffusing elements in the form of one or more structures of a diffuser material may be provided over the wavelength-converter structure of one or more LEDs, the one or more structures being in a light path between the wavelength-converter structure and at least one of the plurality of optical elements, and configured to diffuse light emerging from the wavelength-converter structure.

    摘要: A device for controlling illumination of a scene using an LED array that includes a plurality of individually addressable LEDs, built into a hand-held device, is disclosed. The device includes a controller arranged to configure a first sub-set of the LEDs to provide illumination for a target spot in the scene and to monitor movement of the hand-held device. If the controller detects movement of the hand-held device while the first sub-set of the LEDs is providing illumination, then the controller may configure a second sub-set of the LEDs to continue providing illumination of the target spot. In this manner, even though there may have been movement that could change the specific area illuminated by the LED array, the movement is compensated for, at least partially, by selecting one or more other LEDs to illuminate the same target spot in a manner that is substantially unnoticeable to the user.

    摘要: LED arrays with diffusing elements are disclosed. In various embodiments, diffusing elements in the form of one or more structures of a diffuser material may be provided between an LED array and an optical element that collects light emitted by the array and directs the light to an optical far field. The optical element may image or approximately image the LED array. The diffusing elements at least partially blur patterning in the far field illumination that may otherwise arise from the optical element imaging the array. Each LED may be a wavelength-converting LED in that it may include a light emitter arrangement and a wavelength-converter structure.

    摘要: A lighting apparatus and method of controlling a lighting apparatus are described. A power supply capable of supplying an amount of power is connected to an array of light emitting elements capable of illuminating an area in response to the supplied amount of power. At least some light emitting elements can have independently controllable illumination intensity, with the array of light emitting elements being switchable between a first mode in which each member of the array of light emitting elements received the supplied amount of power and provides a broadly collimated beam, and second mode where a subset of the array of light emitting elements receive the supplied amount of power and provides a narrower collimated beam.
