Definitions

  • the subject of the present invention is a lighting system of at least one key on a device, and in particular on a radiocommunication telephone portable type of mobile or wireless.
  • the present invention aims to overcome the aforementioned drawbacks in offering a space-saving lighting system optimized for the device, and which does not require any energy input from the device.
  • a lighting system of at least minus a key on a device characterized in that it comprises, at the level of said key, an area made of material reactive to ultraviolet radiation, and a source of ultraviolet radiation intended to radiate over said area, said source being positioned at a location separate from said device.
  • the source is advantageously placed on a mobile phone accessory, for example example on the car charger or car-kit, or on the desktop charger.
  • a mobile phone accessory for example example on the car charger or car-kit, or on the desktop charger.
  • This type of accessory is connected to an energy source independent of the battery clean of the mobile phone, namely to the car battery in the case of a car-kit, or to a conventional power outlet in the case of a desktop charger.
  • the source is advantageously placed on the base of the telephone wireless, itself connected on the one hand to a wired telephone network (PSTN), and on the other hand, to the conventional power supply network.
  • PSTN wired telephone network
  • the source can advantageously be placed in the center of the interior roof of the passenger compartment of the car, and thus serve to light a multiple devices, including mobile phone, without the need to add a source on the accessory, typically the car-kit, receiving the phone mobile.
  • FIGs 1 and 2 there is shown schematically an apparatus 1, by example a radiocommunication telephone of the mobile or wireless type, comprising a key keyboard 2.
  • a radiocommunication telephone of the mobile or wireless type comprising a key keyboard 2.
  • these are made of a specific material, or covered with a layer of a specific material, the specificity of this material being that it reacts to a ultraviolet radiation.
  • the radiation source ultra-violet is placed in a separate place from the device 1, so as not to burden energy consumption at device level 1. This is particularly important when the device considered is a portable device with limited autonomy, for example a mobile or wireless phone.
  • the radiation source consists of a plurality of light entities 3 of the LED type arranged on a element 4 separate from device 1, and has its own power supply (not shown).
  • this element 4 is a support intended to receive device 1 (for example a vehicle support known as a "car-kit” or a charger for office in case the device 1 is a mobile phone, or a base if the device 1 is a cordless phone).
  • the position of light entities 3 on element 4 is chosen so as to obtain a direct radiation of these entities on the keys 2 when the device 1 is in place on the element, as shown in figure 2.
  • the position can be that shown in Figures 1 and 2, or any other position to obtain the same result (radiation on the side, or from above the device ).
  • the light source will be composed of a plurality of light entities, as shown in Figure 1. This provides the most radiation homogeneous possible.
  • the system described lighting has the advantage of achieving a non-aggressive lighting of device keys. This is particularly important in such an environment than a car driven at night, in which all too violent lighting is proscribe.
  • the invention can be applied to any type of device comprising a control or navigation or dialing key which must be visible to the user.
  • the invention also finds its application for car radio devices with a removable bar when the user is not in his car.
  • the radiation source is then advantageously positioned on the support of the car radio intended to receive the bar. More generally, the radiation source can be positioned at any location as shown in Figure 3, by example in the interior of a car, without the need to incorporate it in a dedicated accessory of the device for which you wish to make visible the keys.
