The light source, the luminescent material and/or the shielding means are changeable from a first situation to a second situation. In the first situation the color-tunable illumination system is arranged for shielding at least part of the luminescent material against impinging light of the first predefined color.

  • Patent number: 8282239
    Abstract: A light-directing apparatus for off-axial preferential-side distribution of light from a light emitter having an emitter axis, including a lens member positioned over the light emitter and a shield member. The lens member has a proximal end substantially transverse the emitter axis and an outer surface which may be configured for refracting light from the emitter. The shield member may be snugly received in a shield-receiving void of an inner surface of the lens member. Alternatively, the shield member is embedded by the lens member having been molded thereabout. Another aspect of this invention is a lighting fixture utilizing such light-directing apparatus.

  • Patent number: 8256921
    Abstract: An apparatus, system and method for lighting an area, for example, an outdoors pedestrian area or building facade or an auto traffic area, or an indoor large area, which provides indicator/guide light, reference light for structures, and task lighting for a target area. The method uses first lighting sources that are directly viewable by observers and which can be historical, architectural, or aesthetically selected sources, but which produce a relatively low level of light or luminance insufficient to effectively light the area but sufficient to act as an indicator or guide, as well as to provide reference illumination on buildings or structures. Second lighting sources are configured to produce directional light to light the area but hide the light sources from most conventional observer viewing angles and may be enclosed within the general outlines of the globe or transmissive surface area of the fixture.

  • Patent number: 8192060
    Abstract: An aircraft navigation light comprises a base and circuit board in thermal contact with the base. White and colored LEDs mount on the circuit board. A reflector-shade placed adjacent the LEDs reflects light from the LEDs in desired directions and shades other directions from view of selected LEDs. A light transmissive cover sealed to the base, encloses the circuit board, LEDs and reflector-shade. Temperature responsive circuitry on the circuit board regulates the current through the LEDs and reduces the LED current under high temperature conditions.

  • Patent number: 7993030
    Abstract: A lighting system comprises a housing suitable for mounting to a structural unit. The housing includes a plurality of enclosure panels. At least two light-bearing members are moveable relative to the housing and are pivotally coupled one to another. A pair of actuators are moveable in opposing directions, one of the light-bearing members being coupled to one of the actuators and an other of the light-bearing members being coupled to an other of the actuators. Movement of the actuators relative to one another results in pivotal movement of the light-bearing members relative to one another, causing an end of each light-bearing member to move further from or closer to the housing.
