摘要：

A lighting apparatus for use with a name plate sign includes an elongate frame having a planar bottom with an upper portion defining an interior space. The frame bottom includes a bracket for attachment to the name plate. A rechargeable battery is mounted within the interior space of the frame and is electrically connected to a plurality of light sources depending from the frame bottom. A thin film solar panel is positioned atop the upper frame portion and is electrically connected to the battery to repeatedly recharge it as the panel collects solar energy. A photoelectric light sensor is mounted to the frame and permits current to flow from the battery to the light sources when a sensed level of ambient light is less than a predetermined level. Therefore, the name plate is illuminated when insufficient ambient light is available.
