Abstract
Description
La présente invention a pour objet un téléphone portable comportant 5 uneThe present invention relates to a mobile phone comprising a
alimentation électrique de type photovoltaïque. photovoltaic type power supply.
Elle se rapporte d'une manière générale au domaine industriel et commercial de la fabrication et de la diffusion de téléphones transportables sans fil ou "mobiles" permettant de communiquer de tous lieux, et en particulier en déplacement. It relates in a general way to the industrial and commercial field of the manufacture and the diffusion of mobile telephones cordless or "mobile" allowing to communicate of all places, and in particular on the move.
L'es appareils de ce type sont actuellement alimentés par une batterie électrique dont l'autonomie est limitée en particulier en raison de son poids nécessairement réduit pour ne pas alourdir le téléphone qui en est équipé. Celà entraîne l'obligation de recharges périodiques assez fréquentes et il n'est pas rare de voir une conversation s'interrompre de façon intempestive parce que la batterie est arrivée en fin de charge. The devices of this type are currently powered by an electric battery whose autonomy is limited especially because of its weight necessarily reduced to not weigh down the phone that is equipped. This entails the obligation of frequent periodic recharges and it is not uncommon to see a conversation stop unexpectedly because the battery has arrived late charging.
Or il existe depuis un certain temps déjà un moyen permettant de produire de l'électricité à partir du rayonnement lumineux ambiant dont la longueur d'onde peut être comprise dans le spectre visible, dans l'infrarouge ou l'ultraviolet. Il s'agit de la photoélectricité qui, dans certains corps (semiconducteurs, notamment), libère des électrons sous l'effet de l'énergie communiquée par les photons qui les atteignent, ce qui provoque, sous l'effet d'un flux lumineux, l'apparition d'une différence de potentiel entre deux couches d'une plaquette de semi- conducteur dont les conductibilités sont opposées, ou entre un semi- conducteur et un métal. Ce phénomène a donné lieu à la réalisation des cellules photovoltaïques, ou photopiles, ou piles solaires, qui transforment directement l'énergie lumineuse en énergie électrique. However, there has been for some time now a means for producing electricity from ambient light radiation whose wavelength can be in the visible spectrum, in the infrared or the ultraviolet. This is the photoelectricity which, in some bodies (semiconductors, in particular), releases electrons under the effect of the energy communicated by the photons that reach them, which causes, under the effect of a luminous flux. , the appearance of a potential difference between two layers of a semiconductor wafer whose conductivities are opposite, or between a semiconductor and a metal. This phenomenon has led to the production of photovoltaic cells, or solar cells, which directly transform light energy into electrical energy.
L'efficacité des cellules photovoltaïques ne cesse de croître et les dernières réalisations dans ce domaine atteignent, sous un volume très réduit, un rendement suffisament élevé pour fournir le courant électrique nécessaire pour faire fonctionner des systèmes électroniques. The efficiency of photovoltaic cells continues to grow and the latest achievements in this field reach, under a very small volume, a sufficiently high yield to provide the electric current needed to operate electronic systems.
Ces équipements sont déjà utilisés pour recharger les batteries de téléphones mobiles. These devices are already used to recharge mobile phone batteries.
On peut citer par exemple la demande de brevet N WO 007 6051 qui décrit un bloc d'alimentation portatif spécialement conçu pour la recharge de blocs batteries de téléphones portables et comprenant un boîtier dont au moins une surface est pourvue de plusieurs cellules solaires couplées à un circuit de commande de la tension d'alimentation du bloc batterie à recharger. For example, patent application WO 0076051 describes a portable power supply unit specially designed for recharging cell phone battery packs and comprising a housing having at least one surface provided with a plurality of solar cells coupled to a circuit for controlling the supply voltage of the battery pack to be recharged.
Un autre brevet, publié sous le numéro FR 2 844 660 concerne un dispositif d'alimentation pour la recharge de batterie, caractérisé en ce qu'il 10 comprend un film solaire composé d'un substrat souple sur lequel est déposée une pluralité de cellules solaires photovoltaïques utilisées comme source d'énergie électrique et des moyens de connexion électrique vers la batterie. Another patent, published under the number FR 2 844 660 relates to a power supply device for battery charging, characterized in that it comprises a solar film composed of a flexible substrate on which a plurality of solar cells is deposited. photovoltaic cells used as a source of electrical energy and means of electrical connection to the battery.
Malheureusement, ces chargeurs augmentent l'encombrement du téléphone, ce qui va à l'encontre d'un des principaux intérêts de ces appareils qui est précisément leur taille de plus en plus faible permettant de les loger aisément dans une poche ou un sac à main. Unfortunately, these chargers increase the size of the phone, which goes against one of the main interests of these devices which is precisely their smaller and smaller size for easy housing in a pocket or purse .
