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