  • Publication number: 20030137838
    Abstract: A highly efficient LED lamp includes an optical module and a housing. The optical module has at least one light emitting diode (LED) that emits light with a wide divergence, a non-imaging optical (NIO) element and a transparent window. The NIO element includes a refractive member located around a LED optical axis and a total internal reflection member located around the refractive member. The refractive member and the total internal reflection member are integrated in a single transparent element having a mutual focal point, wherein the NIO element collects a significant amount of light emitted by the LED with wide divergence located at the focal point, to compress the collected light with high efficiency into a beam with a generally different angular spread in a horizontal plane and a vertical plane and to direct the compressed light outside of the lamp.

  • Patent number: 6565239
    Abstract: A luminaire flush with a horizontal surface and comprising a housing, an optical window, a light source, and an optical element. The housing has an internal cavity disposed beneath the horizontal surface and defines an opening disposed adjacent the horizontal surface. The optical window, substantially flat and transparent, has a surface that overlays the housing opening. The light source, disposed within the housing cavity, provides a spatial light distribution pattern which defines an optical axis that is disposed substantially perpendicular relative to the optical window surface. The optical element, also disposed within the housing cavity, redistributes light rays emitted by the light source along preselected angles relative to the horizontal surface.

  • Publication number: 20030072150
    Abstract: A portable luminaire includes an optical module, a power source and a housing. The optical module has at least one light emitting diode (LED) that emits light with a wide divergence, a non-imaging optical element and a transparent window. The non-imaging optical element (NIO) has a refractive member located around a LED optical axis and a total internal reflection member located around the refractive member. The refractive member and the total internal reflection member are integrated in a single transparent element having a mutual focal point. The NIO element collects a significant amount of light emitted by the LED with wide divergence located at the focal point to compress the collected light with high efficiency into a required pattern with a generally different angular distribution in a horizontal plane and a vertical plane, and to direct the compressed light outside of the luminaire.

  • Patent number: 6543911
    Abstract: A highly efficient luminaire. The luminaire includes a light source that emits light. The emitted light is redirected by a light transformer having a curved circular reflective interior surface, the reflective interior surface reflecting the light in a predetermined pattern. A substantial amount of light being may be reflected close to an axis coincident with a radial line defining a radius of the circular reflective interior surface. Additionally, a substantial amount of light may be reflected in a pattern with low divergency or parallel with an axis of the light transformer. The light is transmitted to the exterior of the luminaire by an optical window.

  • Patent number: 6201915
    Abstract: A remote light source lighting system is provided having an illuminator assembly including a housing. Held within the housing is a high intensity light source for providing light energy to a fiber optic cable bundle connected to the housing and facing the light source. The cable bundle includes a plurality of plastic optical fibers wherein at least one of the terminal ends of the bundle is formed by molding an optical quality resin around an optically transparent ferrule that binds the exposed ends of the optical fibers. The housing further includes a separate air plenum containing a blower. The blower produces a high velocity air stream directed precisely at the terminal end of the cable adjacent the light source to cool the terminal end.

  • Patent number: 6155703
    Abstract: Surface light assemblies are disclosed that are particularly useful as edge light assemblies for illuminating the outer boundaries of a deck of a ship or a heliport and as line-up light assemblies for illuminating a path on a surface such as a ship deck, a runway or the like. The light assembly includes a fiber optic cable connected to the bottom of a housing or enclosure which distributes light from a terminal end of the cable. The terminal end may include a transformer which produces a particular spread or cone of a light output pattern. Alternatively, a diffuser or optical element may be placed directly adjacent the terminal end of the cable or transformer which shapes, directs and homogenizes light emanating from the cable. The light assembly can include a durable glass window which protects the diffuser and cable and which can be adapted to filter out certain wavelengths of light producing a light output in a desired color. Such a construction is particularly useful for deck edge lighting.

  • Patent number: 6152577
    Abstract: An illuminator for a high energy remote lighting system includes a light source for generating light energy and a selectively positionable light output modifying apparatus having a plurality of light output modifying elements, each element corresponding to a predetermined position of at least a portion of the apparatus. At least some of the light output modifying elements of the apparatus are configured to filter light energy to provide either dimmed or colored light. The illuminator can be implemented in a system having a plurality of area control panels, each control panel generating a control signal indicative of a corresponding light characteristic, the illuminators each being coupled to a corresponding one of the area control panels to receive the control signal and to output a particular type of light in response thereto.

  • Patent number: 5986792
    Abstract: A remotely illuminated lighting system (10) incorporates a lighting system sequencer (18) for providing a sequenced distribution of light signals to a plurality of light distribution devices (108, 208, 210 and 212). An illumination source (12) provides focused light signals (44, 46) to the lighting system sequencer (18). The lighting system sequencer (18) includes an optical scanner (22) and an electronic control (24) for selectively directing the light signals (44, 46) to individual optical fibers (20) of a fiber-optic distribution system. The optical fibers (20) couple the light signals to the luminaires (108, 208, 210 and 212), which sequentially illuminate in accordance with a desired pattern.
