  • Patent number: 10378731
    Abstract: A lighting module has an LED (44), a lens (45) over the LED to produce a beam-shaped output from the LED and a collimator (50) arranged to partially collimate the beam-shaped out-put. Blue light is provided at large angles to the normal, for example using a filter arrangement (54, 56) over the collimator which is adapted to filter light from the collimator at relatively large angles to the normal. The filter arrangement does not filter light from the collimator at relatively small angles to the normal. Thus, the module provides white task light in a normal direction and blue ambient light at steep angles. The overall system can be compact and light efficient.

  • Patent number: 10309595
    Abstract: An LED beacon has a base and four vanes upon the base extending radially outward from a central axis which lies perpendicular to an upper surface of the base. The vanes are formed using two circuit boards that intersect each other at a right angle, in which each of the circuit boards provides two of the vanes extending outwards in opposite directions from the central axis. Each vane has two opposing surfaces, and upon each such surface are mounted, in proximity to the central axis, one or more LEDs producing same color or different colors of light. A controller enables the LEDs to output light in multiple modes of solid on, flashing and/or rotating patterns along the 360 degree extent of a lens upon the base, and substantially along the height of the lens, for projection preferably as collimated light. LED beacons thus having mono-color and multicolor operation are provided.

    Abstract: A recessed light includes an enclosure with a cavity, an opening into the cavity and a mounting surface about the periphery of the opening. An intermediate light assembly including a peripheral frame and a lamp is mounted on the mounting surface of the enclosure. The peripheral frame includes a main frame and extension rings which can be stacked to extend the lamp away from the cavity. The lamp has an array of light emitting diodes on a substrate which is affixed to and thermally integral with a pivotally mounted reflector mounted to the peripheral frame. The reflector provides cooling fins for the array of light emitting diodes. A lens associated with a lens frame is attached to the intermediate lamp assembly.

  • Patent number: 8622569
    Abstract: An apparatus, method, or system of lighting units comprising a plurality of individually positionable lighting elements, such as one or more LEDs, each element optionally having an associated optic. In embodiments of the present invention, one or more optics are developed using optimization techniques that allow for lighting different target areas in an effective manner by rotating or otherwise positioning the reflectors, refractive lenses, TIR lenses, or other lens types to create a composite beam. The apparatus, method, or system of lighting herein makes it possible to widely vary the types of beams from an available fixture using a small number of inventoried optics and fixtures. In some cases, by using a combination of individual beam patterns, a small set of individual optics would be sufficient to create a majority of the typical and specialized composite beams needed to meet the needs of most lighting projects and target areas.

  • Publication number: 20130300911
    Abstract: New optic control systems are provided that manage camera, user or environmental movement and other factors impacting optical and resulting image quality. In some aspects of the invention, a variably, directionally shadable semi-transparent matrix and actuating system is provided, which limits problematic glare for an observation point. In other aspects of the invention, a matrix creates directional light from a plurality of shiftable and angle-directable sources, which may aid in creating virtual, 3-D objects of greater realism than conventional 3-D imaging methods and aid in reducing the appearance of distracting interceding objects (e.g., finger blocking a touch screen). In still other aspects of the invention, electromagnetically actuated optical control techniques, including rotational lenses and sensors, are provided.

    Abstract: The present invention relates to an illumination device comprising at least one light source and a reflector system forming a spotlight (1), one or several actuators (5) arranged to pivot the spotlight (1) relative in a mounting base (4) for varying an illumination angle, and a camera (13) attached to the spotlight (1) and aligned to acquire images of an illumination region (7) to which the spotlight (1) is directed. The spotlight (1) is designed to comprise a central region from which the illumination region (7) is visible and which does not reflect or emit light of the light source towards the illumination region (7), wherein the camera (13) is arranged in said central region on an optical axis (14) of the spotlight (1). With the proposed illumination device an exact aiming of the spotlight (1) can be achieved even in applications in which the illuminated region (7) is close to the spotlight (1) without causing undesired shadows in the illumination region (7).
