Definitions

  • the invention relates to an operating device for a communication device, in particular a remote control for a device of entertainment electronics according to the preamble of patent claim 1.
  • Remote controls are commonly used as so-called remote control transmitters for operating consumer electronic devices, such as televisions, video recorders and audio devices. Since such remote controls are often to be operated by the user in darkened rooms, also remote control transmitter are known whose keypads are illuminated.
  • EP-A-0414366 is known a light guide for illuminating an information-carrying element.
  • a translucent plate having at least one region connected to the information-carrying element, the plate having means for reflecting light from an external light source into the plane of the plate.
  • the reflecting means comprise a first reflecting means which directs light from the light source in a first direction in the plane of the plate, and a second reflecting means, the light from the first reflecting means in a second direction, transverse to the first direction and in the plane the plate reflects.
  • a third reflecting means which reflects light from the second reflecting means in a third direction, transverse to the second direction and in lateral, parallel, but opposite to the first direction, and in the plane of the plate.
  • the invention has for its object to provide an operating device of the type mentioned above, the keypad is illuminated as homogeneously as possible without great effort and is easy to produce.
  • the light-conducting means homogenous distribution of the available light, in particular to the edge regions of the buttons to be illuminated, resulting in a simpler and more ergonomic handling of the Whyseininoplasty even in darkened visibility.
  • Fig. 1 shows a first embodiment of a keypad 1 as a section in the side view.
  • the keypad 1 consists of keys 2 which are surrounded by light-guiding means 9. Between the buttons 2 each light emitting diodes 8 are arranged.
  • Fig. 2 shows that in Fig. 1 illustrated keypad in plan view.
  • the keypad 1 is part of an operating device, such as a remote control for a TV.
  • the keypad contains buttons 2 for activating certain device functions.
  • buttons 2 for activating certain device functions.
  • In the area between the keys 2 are in the in Fig. 2 illustrated embodiment, four LEDs 8 are provided which are provided for illuminating the area surrounding the keys 2.
  • Each key 2 is surrounded by a light guide 9 for this purpose.
  • the light-guiding means 9 are formed as circular rings, and consist of a transparent material. This material can also be colored to produce certain optical effects.
  • the individual rings of the light-guiding means 9 are integral to the simplified manufacture of the operating device, i. produced as a coherent rings.
  • Fig. 3 shows a further embodiment of a keypad in cross section.
  • the keypad 1 consists of keys 5, 6, 7, which are surrounded by light-guiding means 9.
  • the light is transmitted to the light guide 9.
  • the light-guiding means 9 are connected to a notch. Accordingly, in the upper area 11 of Lichtleitstoff another notch provided.
  • the function for illuminating the keypad 1 corresponds to the in Fig. 3 illustrated embodiment, substantially in the context of Fig. 1 and Fig. 2 explained embodiments, so that reference is made to the simplification to the relevant description.
  • Fig. 4 shows that in Fig. 3 illustrated keypad in plan view.
  • the keypad 1 has keys 3, 4, 5, 6, 7, which are provided for activating certain device functions of a consumer electronics device.
  • the edge regions of the keys 3, 4, 5, 6, 7 are surrounded by light-guiding means 9.
  • the entire keypad 1 is framed by another light guide 12.
  • light-emitting diodes 8 covered by the operating device are provided in the keypad.
  • LEDs 8 is in the in Fig. 4 illustrated embodiment in addition to lighting only the surrounding area of the keys 3, 4, 5, 6, 7 also achieves illumination of the entire keypad 1.
  • illustrated light guide 9, 12 are can be made in one piece from a translucent material.
