Publication number: 20120139843Abstract: A light guide is provided for illuminating innumerable constructions, but which is ideally suited for illuminating the keys of a keyboard. The light guide includes a translucent planar plate having a top, a bottom and sides. Further, the light guide includes one or more cavities which project upwardly into the translucent plate from its bottom surface. The cavities are hollow or filled with a translucent material so that the translucent plate and the one or more cavities form translucent interfaces where the cavities interface with the plate. The light guide also includes a reflector which covers the plate bottom and cavity openings.Type: ApplicationFiled: January 12, 2012Publication date: June 7, 2012Inventors: Michael Shipman, David G.

Patent number: 8189008Abstract: A method and apparatus whereby a two-dimensional touchpad control for selecting color is implemented via a touch sensitive surface with a graphical attachment on its surface to select both an intensity and a color. The graphical attachment having two regions, one region being a rectangular shape to select the intensity via a Y-axis and the other being a two dimensional X/Y-axis control surface with color Hue on one axis and color Saturation on the other axis. Software running in a control device monitors touchpad regions for user inputs and converts the raw selected parameters on the touchpad into the Hue, Saturation and Intensity information, used in the preferred embodiment to control light fixture color and intensity.Type: GrantFiled: December 10, 2008Date of Patent: May 29, 2012Inventor: Daniel John Julio

Patent number: 8184021Abstract: A keyboard with illuminating architecture includes a keyboard portion and a substrate carrying the keyboard portion, wherein the keyboard portion includes a plurality of pressing elements for receiving a pressing force from the user and inter-dependent mechanisms respectively under a force receiving surface of each pressing element for providing a moving stroke of the pressing element following the force direction, and the substrate has an assembling portion for assembling with the other end of the inter-dependent mechanism. Moreover, the surface of the substrate has at least one light guiding groove, which forms a light channel for transmitting light, and at least one inner sidewall of the light guiding groove is a light reflecting surface, so that the light in the light guiding groove is reflected by the light reflecting surface to the keyboard portion, thereby providing the pressing elements the brightness, and reducing whole keyboard thickness and thinning.Type: GrantFiled: August 15, 2008Date of Patent: May 22, 2012Assignee: Zippy Technology Corp.Inventor: Chin-Wen Chou

Publication number: 20120113013Abstract: A keyboard comprises a key module and a backlight module in which the key module comprises a light-transmissive key part and an electric circuit substrate, and the backlight module comprises a light guide plate, a reflection unit and at least one light source. The backlight module is disposed between the key part and the electric circuit substrate. Thus, lights emitted by the light source are projected into the light guide plate from the lateral side of the light guide plate, and the lights are reflected by the reflection unit for directly passing through the light output surface of the light guide plate and the key part.Type: ApplicationFiled: September 23, 2011Publication date: May 10, 2012Applicant: GLOBAL LIGHTING TECHNOLOGY INC.Inventors: Guo-Chen LEE, Jerry WU, Yu-Jeng LIN, Tsung-Yung HUNG, I-Ping HUANG

Patent number: 8174304Abstract: A key module includes a key, a light emitting component, and a drive circuit. The key is operable between on and off states. The light emitting component is disposed adjacent to the key, and is capable of providing indicating light for the key. The drive circuit is electrically connected to the key and the light emitting component. The drive circuit is triggered upon switching of the key from the off state to the on state to provide a drive signal for driving the light emitting component to provide the indicating light. The drive signal has an intensity that gradually decreases over time once the key switches from the on state to the off state such that the indicating light provided by the light emitting component has a luminance that gradually decreases over time.Type: GrantFiled: September 5, 2007Date of Patent: May 8, 2012Assignee: Coretronic CorporationInventors: Lien-Fu Cheng, Wei-Chih Su, Jyh-Yu Chuang

Patent number: 8164030Abstract: An appliance including a top plate has its operability improved and prevents an operation error. The appliance includes electrostatic touch keys provided on a lower surface of the top plate, the electrostatic touch keys including electrodes made of conductive films having predetermined light-blocking property, respectively, operation-unit illuminators emitting light toward the electrodes, which are partially cut, from a direction opposite to the top plate, respectively, and an illumination controller controlling illumination of the operation-unit illuminators. The illumination controller changes the illumination state of the shapes of key indicators above the electrodes to allow a user to identify function and validity of the electrostatic touch keys. The illumination controller controls the illumination state of operation-unit illuminators, such as lighting-on, blinking, lighting-off, and adjusting the brightness, to provide information required for operation.Type: GrantFiled: July 26, 2007Date of Patent: April 24, 2012Assignee: Panasonic CorporationInventors: Keiko Isoda, Ryuuji Nagata, Chikashi Satou, Tsuyoshi Inada
