Patent number: 8534890Abstract: A light pipe assembly includes a light pipe and an optical concentrator. The light pipe is elongated between opposite ends along a longitudinal axis. The light pipe is formed from a light transmissive material. The optical concentrator is joined to the first end of the light pipe and includes an end section and an opposite coupling end connected to the first end of the light pipe. The end section is configured to receive light generated by a light source. The optical concentrator is formed from a light transmissive material that conveys light through the optical concentrator. The optical concentrator focuses the light generated by the light source into the first end of the light pipe.Type: GrantFiled: October 6, 2009Date of Patent: September 17, 2013Assignee: Tyco Electronics Canada ULCInventors: Kazuhiro Goto, Dragos Luca

Patent number: 8070343Abstract: A light pipe is configured to provide a wide effective angle of illumination while simultaneously providing a substantially uniform distribution of light along a length of the light pipe. One or more reflective surfaces not aligned with an inner surface are disposed such that when at least one reflective surface is illuminated, light is emitted from the light pipe at one or more specified angles of light emission. A plurality of reflection points are formed on the inner surface to cause the specified angles when at least one of the reflective surfaces is illuminated. A light pipe is also provided having one or more exterior protrusions configured to function as a secondary light source. A second portion of an outer surface of the light pipe has a radius of curvature which differs from the radius of curvature of the first portion of the outer surface.Type: GrantFiled: April 23, 2009Date of Patent: December 6, 2011Assignee: Tyco Electronics Canada ULCInventors: Kazuhiro Goto, Dragos Luca, Salvatore Alesio

Patent number: 6883949Abstract: A light pipe having one or more exterior protrusions that function as a secondary light source and an alignment component. The one or more exterior protrusions may provide a secondary light source by reflecting light from a primary light source. The one or more exterior protrusions also may function to align the light pipe with a lamp assembly or an object on which the light pipe is mounted. Further, a lamp assembly having a light pipe receiving portion, with one or more slits to allow an opening to expand upon insertion of the light pipe, and to provide a retention force upon contraction.Type: GrantFiled: September 17, 2002Date of Patent: April 26, 2005Assignee: Tyco Electronics Canada Ltd.Inventors: Kazuhiro Goto, Andras Gyimes, Ronald Charles Du Pont, Dragos Luca

Patent number: 6769799Abstract: A light pipe may be used to illuminate an elongated area. Light may emanate laterally relative to the axis of the light pipe, and the light intensity is substantially uniform along the length of the light pipe. The light pipe may include a translucent member and a opaque reflective member that is separated from the translucent member by an air gap. A band of reflective material may be located on an exterior surface of the translucent member. The entire light pipe may be formed by co-extrusion of the translucent member, the band of reflective material and the opaque section through a single co-extrusion die. Light emitted laterally from the translucent member toward the arcuate opaque reflective member and band of reflective material may be reflected laterally through the translucent member transverse to the axis of the light pipe, so that all light extends through the front surface of the translucent member.Type: GrantFiled: March 10, 2003Date of Patent: August 3, 2004Assignee: Tyco Electronics CanadaInventors: Kazuhiro Goto, Dragos Luca

Light may emanate laterally relative to the axis of the light pipe, and the light intensity is substantially uniform along the length of the light pipe. The light pipe may include a translucent member and a opaque reflective member that is separated from the translucent member by a space. A band of reflective material may be located on an exterior surface of the translucent member. The entire light pipe may be formed by co-extrusion of the translucent member, the band of reflective material and the opaque section through a single co-extrusion die. Light emitted laterally from the translucent member toward the arcuate opaque reflective member and band of reflective material may be reflected laterally through the translucent member transverse to the axis of the light pipe, so that all light extends through the front surface of the translucent member.Type: ApplicationFiled: March 10, 2003Publication date: September 18, 2003Applicant: Tyco Electronics CanadaInventors: Kazuhiro Goto, Dragos Luca

Patent number: 6095673Abstract: A light transmitting strip or light pipe 2 is used to illuminate an elongate area along which the light pipe 2 extends. The illumination is provided by light emanating laterally relative to the axis of the light pipe, and the light intensity is substantially uniform, at least to an observer, along the length of the light pipe 2. The light pipe 2 has a clear light guide section 4 and an opaque section 10 that is separated from the light guide section 4 by an air gap 8. The clear section 4 and the opaque section 10 are joined by top and bottom couplings 12 and 14, and the two sections are formed by coextruding an acrylic resin through a single coextrusion die. Light emitted laterally from the light guide 4 toward the arcuate opaque section 10 is reflected laterally through the clear light guide 4 transverse to the axis of the light pipe 2, so that all light extends through the front surface 6 of the light guide 4.Type: GrantFiled: January 20, 1998Date of Patent: August 1, 2000Assignee: The Whitaker CorporationInventors: Kazuhiro Goto, Andras Gyimes, Dragos Luca, Ronal C.
