A plurality of light guiding pipes are inserted into to the holding body of the holding member.

An apparatus for concentrating light from a light source includes a plurality of fibers that are substantially parallel with one another. Each fiber includes a light-receiving end and a light-transmitting end. The light-receiving end is configured to receive the light from the light source. The light-transmitting end is configured to transmit the light from the fiber. The light-receiving ends the fibers extend different distances from a plane that is perpendicular with respect the fibers.

The present disclosure provides an apparatus for generating fiber delivered laser-induced white light. The apparatus includes a package case enclosing a board member with an electrical connector through a cover member and a laser module configured to the board member inside the package case. The laser module comprises a support member, at least one laser diode device configured to emit a laser light of a first wavelength, a set of optics to guide the laser light towards an output port. Additionally, the apparatus includes a fiber assembly configured to receive the laser light from the output port for further delivering to a light head member disposed in a remote destination. A phosphor material disposed in the light head member receives the laser light exited from the fiber assembly to induce a phosphor emission of a second wavelength for producing a white light emission substantially reflected therefrom for various applications.

The present invention relates to a vehicle lighting device including a first light guide and a second light guide each adapted to emit at least a part of a lighting function. The first light guide has a main light guide part, a fixing part fixing the main part to the second light guide and extending between the main part and the second guide so that one of the guides supports the other one in said lighting device.

The invention relates to a light guide block made up of a plurality of light guide rods (9) that are molded in a curable filler material, wherein for manufacturing the light guide block (1, 2), the curable filler material is fillable into an at least half-open trough (3), the light guide rods (9), as plastic injection-molded parts or plastic molded parts, being molded onto surfaces (4-8) of the trough (3) that is made, at least partially or in sections, of light-conducting plastic.

Disclosed herein is an optical fiber assembly comprising a launching fiber having a receiving end and a transmitting end; an illuminating fiber having a receiving end and a transmitting end; where the receiving end of the launching fiber is operative to receive light from a light source and the transmitting end of the launching fiber is operative to transmit light to the receiving end of the illuminating fiber; where the launching fiber contacts the illuminating fiber in a manner so as to be offset from a center of a cross-sectional area of the illuminating fiber; and where the launching fiber has a diameter that is ⅛ to ½ of a diameter of the illuminating fiber; and a lens that is operative to contact the transmitting end of the illuminating fiber.

An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.

A system simulating an open candle flame is provided in the present invention. In a preferred embodiment, the present system comprises a gyro-levitation unit including two spinning wheels with axes mutually perpendicular to each other to allow a two-degree of rotational freedom resembling the open candle flame motion caused by air flow in its surrounding environment. A mechatronics based actuator made of a bi-metal is employed to disturb the equilibrium of the gyroscope by exerting an actuating force against the gyro-levitation unit. Electric current controlled by a dedicated electronic unit flowing through the actuator allows reciprocal linear motion aligned with the visible light pattern of the candle flame. Varying light intensity of the candle flame is obtained as a combination of two light sources with one transmitted to a flame display through an optical device by total internal reflection and another one by projecting on its sideway.

A shield cage assembly of the present disclosure comprises a metal shield shell and a heat dissipating module. The metal shield shell comprises a plurality of walls and an accommodating space defined by the plurality of walls, and the accommodating space has a front end port. The heat dissipating module is assembled to one of the walls of the metal shield shell, and the metal shield shell further includes side walls respectively positioned at two sides of the wall to which the heat dissipating module is assembled. The heat dissipating module further includes a frame and a first heat dissipating member, the frame having a frame body formed at a central portion of the frame to receive the first heat dissipating member and two side plates which extend from two side edges of the frame and which are parallel to the side walls.

The present invention relates to a light guiding apparatus, comprising a light transmitting polymer guide having a first end, a second end extending from the first end, and a light path extending between the first end and the second end, and at least one light reflector disposed along the light path and at an angle relative to the light path. The present invention also relates to a method of fabricating the light guiding apparatus.
