Patent number: 6886955Abstract: An illumination structure includes an operation button having a front face on which is formed an identifying indication of ‘AUTO’ made by exposing an opalescent synthetic resin to easily penetrate light and the other parts are painted in black. It also includes an illuminating part provided on a back of the operation button, which illuminates a back of the identifying indication, and plural protrusions in a shape of ribs that regulate an intensity of light penetrating through the identifying indication. In this structure, the plural protrusions obstruct and diffuse the light beams that advance from the illuminating part toward the back of the identifying indication, thereby achieving uniform emission of the light beams from the whole identifying indication. Further in the manufacturing process of the operation button, contraction of a front face of the operation button accompanied with coagulation of the synthetic resin is dispersed by the plural protrusions.Type: GrantFiled: October 16, 2002Date of Patent: May 3, 2005Assignee: Alps Electric Co., Ltd.Inventor: Yasuhiro Miyasaka

Patent number: 6820990Abstract: The present invention relates to illumination of an instrument for displaying information. In particular the invention relates to illumination for an instrument suitable for use in a vehicle. Such instruments, located on the dashboard of an automotive vehicle, require illumination to allow the driver to read the information when it is dark. An instrument suitable for use in a vehicle is thus provided, generally comprising a housing, an information bearing surface, a transparent protective cover having an interior surface and an exterior surface, and a first light source coupled to the protective cover. The protective cover acts as a light guide and is arranged to allow light to escape at a selected location into the interior of the instrument to illuminate a portion of the information bearing surface.Type: GrantFiled: December 12, 2002Date of Patent: November 23, 2004Assignee: Visteon Global Technologies, Inc.Inventors: Paul Simon Ewers, Maryline Thorailler, Pascal Guirauton

Publication number: 20040184255Abstract: An instrument cluster for communicating a vehicle's operating status to a vehicle occupant is disclosed. The instrument cluster includes a housing for supporting the instrument cluster. The housing is mountable to a vehicle instrument panel. A circuit board is secured to the housing. A motor having a motor shaft is rotatably coupled to the motor and the motor is secured to the circuit board. A gauge pointer is mounted on the motor shaft and rotatable therewith for indicating the vehicle's operating status. At least one diode is provided for illuminating the gauge pointer and at least one diode “footprint” is disposed on the circuit board proximate the motor shaft for electrically interconnecting the at least one diode to the circuit board. The at least one diode “footprint” has a cathode solder pad and an anode solder pad. The anode solder pad is substantially rectangular and the cathode solder pad is substantially L-shaped.Type: ApplicationFiled: March 17, 2003Publication date: September 23, 2004Inventors: Christopher L. Rovik, Wesley R. Corrion, Ricardo Hernandez, Adrian G. Gheorghiu

Publication number: 20040145885Abstract: Gauge face lighting includes an illuminative device disposed on top of a gauge face with mechanical meters; the device features on that the illuminative device is composed by a circular light guiding loop and a plurality of grooves. A plurality of light-emitting diode is disposed inside the grooves respectively. Thus the homogeneous light emits circularly from the light guiding loop for better lighting on the surface of the gauge face with mechanical meters.Type: ApplicationFiled: January 27, 2003Publication date: July 29, 2004Inventor: Kuan-Hsu Chen
