A solar battery type indication apparatus comprising: a solar battery; a capacitor for accumulating electric power generated by said solar battery; light-emitting diodes for emitting light on the basis of said electric power supplied from said capacitor; an indicator for making a necessary indication on its front surface; and optical fibers with their one-ends disposed to face said light-emitting diodes and with their other-ends disposed on said indicator; wherein the capacitor is constituted by an electric double-layer capacitor and the necessary indication on the indicator is performed by using characters, figures and/or symbols. In this occasion, the following configurations are thought of: a configuration in which the indicator is made hollow so that the electric double-layer capacitor and the light-emitting diodes are put in the inside of the indicator, and the solar battery is put on the upper surface of the indicator so as to be united with the indicator into one body; a configuration comprising optical fiber bundles disposed respectively correspondingly to characters, figures and/or symbols indicated on an indicator and light emitting diodes provided respectively correspondingly to the optical fiber bundles and a control portion for controlling light emitting states of the respective light emitting diodes individually; a configuration in which in a solar battery type indication apparatus comprising light emitters for emitting light in response to electric power generated by a solar battery, and an indicator for leading the light emitted by the light emitters to light-emission ends through optical fibers so as to serve as a sign portion forming a predetermined sign, a portion for binding the optical fibers is arranged substantially in the center of the sign of the indicator; etc.
L'invention est un indicateur du type à pile solaire comportant les éléments suivants : une pile solaire; un condensateur servant à stocker l'énergie électrique engendrée par ladite pile solaire; des diodes luminescentes alimentées en énergie par ledit condensateur; un afficheur affichant une indication sur sa face frontale; des fibres optiques dont une extrémité est aboutée à une diode luminescente et l'autre aboutit à l'afficheur. Le condensateur comporte deux couches et l'indication est affichée au moyen de caractères, de chiffres et/ou de symboles. Les configurations suivantes sont possibles : une configuration dans laquelle l'afficheur est creux et contient le condensateur à double couche et les diodes luminescentes, la pile solaire étant montée sur la surface supérieure de l'afficheur et intégrée à celui-ci; une configuration dans laquelle des faisceaux de fibres optiques sont disposés de façon à correspondre aux caractères, aux chiffres et/ou aux symboles affichés, avec des diodes luminescentes correspondant aux divers faisceaux de fibres optiques respectivement et un bloc de commande servant à contrôler les états de luminescence des diodes luminescentes individuelles; une configuration comportant des dispositifs luminescents alimentés en énergie électrique par une pile solaire et un afficheur servant à transmettre la lumière produite vers l'extérieur au moyen de fibres optiques pour former un signe donné, un élément servant à lier les fibres optiques étant placé approximativement au centre du signe sur l'afficheur; etc.
