Abstract
(EN)
A solar powered lamp (10) utilizing cold cathode fluorescent illumination and means for facilitating same. The solar powered lamp (10) is powered through the utilization of photovoltaic cells (14) which charge a battery (12) for providing power to a cold cathode fluorescent bulb (18) in the absence of sunlight. The cold cathode fluorescent bulb (18) provides increased illumination and a longer lamp life. The solar powered lamp (10) comprises circuitry (16) for converting the low power provided by the battery into an alternating current voltage sufficient to operate the cold cathode fluorescent bulb (18) in order to facilitate a longer lamp life and provide increased illumination. In a preferred embodiment, a lens (20) configured with vertically disposed ribs (22) about its inner surface (24) is disposed about the cold cathode fluorescent bulb (18) which is vertically disposed within the lamp, to further enhance illumination.

La lampe (10) objet de l'invention est alimentée par énergie solaire par l'intermédiaire de cellules photovoltaïques (14) qui chargent une batterie (12) afin de fournir un courant à une ampoule fluorescente (18) à cathode froide, en l'absence de lumière solaire. L'ampoule fluorescente (18) à cathode froide offre un éclairage plus intense et sa durée de vie est plus longue. La lampe (10) alimentée par énergie solaire comprend un circuit (16) destiné à transformer le courant faible fourni par la batterie en un courant alternatif suffisant pour faire fonctionner l'ampoule fluorescente (18) à cathode froide, cela permettant d'allonger la durée de vie de la lampe et d'obtenir un éclairage de plus grande intensité. Dans un mode de réalisation préféré, une lentille (20) dotée de nervures verticales (22) autour de sa surface intérieure (24), entoure l'ampoule fluorescente (18) à cathode froide, ladite ampoule étant placée verticalement à l'intérieur de la lampe pour améliorer encore l'éclairage.
