Patent number: 7625112Abstract: A lamp-supporting unit includes a mold frame and a lamp-fixing member. The mold frame includes a bottom face, a side face upwardly extending from an edge of the bottom face, and a top face horizontally extending from an upper end of the side face and being opposite to the bottom face. The side face has openings through which lamps are moved. The lamp-fixing member is installed on the bottom face of the mold frame and fixes an end of each of the lamps.Type: GrantFiled: September 9, 2005Date of Patent: December 1, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Rok Ko, Jae-Hwan Chun, Jong-Ho Won

Patent number: 7623111Abstract: The invention is intended to change the viewing angle in accordance with a viewer's intention. Disposed between a light source (810) and a liquid crystal display panel (804), a Fresnel lens (812) converts light coming from the light source (810) to approximately parallel light and allows plural images to be displayed to different positions. The light source (810) is configured in such a manner that lighting positions and lighting regions can be changed. Lighting control means for changing the lighting positions or lighted regions of the light sources (810) is provided.Type: GrantFiled: February 20, 2004Date of Patent: November 24, 2009Assignees: Sophia Inc., Arisawa Mfg. Co., Ltd., Amita Technologies, Inc.Inventors: Sadao Ioki, Sanji Arisawa, Seijiro Tomita

Patent number: 7616849Abstract: An optical device for collecting and distributing light from a quasi point light source which includes a planar light guide having surfaces through which optical axes are periodically spaced. There is at least one quasi point light source, the optical axis of each being coincident with the optical axes of the surfaces. There is also at least one optical element depressed within the edges or adjacent surfaces of the light guide at least partially rotated about the optical axis, and having a focal point at the quasi point light source.Type: GrantFiled: March 23, 2006Date of Patent: November 10, 2009Inventor: Jerome H. Simon

Patent number: 7612660Abstract: Instruments or gauges arranged to provide feedback detectable by the peripheral vision of a driver when vehicle operating parameters, such as engine speed, temperature, pressure, and voltage, are in a critical range, include one or more of the following types of instruments or gauges and/or features: (a) a tachometer that not only includes a primary numeric display, but also a secondary display made up of a plurality of discrete lights of different colors, the colors indicating whether the engine speed of a vehicle is within a relatively narrow range of engine speeds acceptable for the roadway leading from a race track to service areas, known as “pit road,” the high and low limits of the range being adjustable to meet pit road requirements at different tracks; (b) an instrument or gauge having a background that illuminates to indicate critical sensor readings; (c) an instrument or gauge having improved handling of sensor abnormalities to prevent false readings; (d) a non-linear analog gauge for a motor vehiclType: GrantFiled: April 20, 2009Date of Patent: November 3, 2009Inventors: John Timothy Sullivan, Steve Parks

Patent number: 7607808Abstract: A light distributing assembly for a vehicle instrument panel includes a light source that emits light in a first direction. A first surface that is transverse to the first direction receives the light and changes the direction of the light to a second direction. A vehicle instrument panel housing having a second surface receives the light from the first surface and reflects a portion of the reflected light toward a vehicle display surface to illuminate the vehicle display surface.Type: GrantFiled: May 10, 2005Date of Patent: October 27, 2009Assignee: Continental Automotive Systems US, Inc.Inventors: Vyacheslav B. Birman, Werner Eckardt, Christian Jean Tanguy
