Abstract

A solar powered illuminated device is provided with a power module electrically connected to an illuminated module, the power module having a solar cell array electrically connected to a battery array having at least one rechargeable battery, the battery array being electrically connected to the illuminated module. The power module utilizes a power charging mode during generally daylight hours to charge the battery array with energy generated and provided by the solar cell array, and a photo switching device to switch from the power charging mode to a power source mode during generally non-daylight hours to enable the battery array to discharge current to the illuminated module to light up one or more housings in the illuminated module with a light source mounted in each housing. A display plate manufactured of one or more or a combination of opaque, translucent and transparent materials is positioned adjacent or proximate to a non-reflective side of each housing to display any of alphanumeric characters, symbols and/or designs utilizing the device without illumination during the daylight hours and with illumination during non-daylight hours.
