发明名称 Solar powered address indicator with rechargeable and replaceable batteries
摘要 An address indicator has panels each displaying a translucent character surrounded by an opaque area. A frame with a channel slidably captures the panels and has an upper chamber above the channel and a rear chamber behind the channel. Stops at opposite ends of the channel keep the panels in the channel and lights such as LEDs are spaced in the upper chamber for casting light into the rear chamber. A translucent screen in the rear chamber defuses light for illuminating the translucent character of each panel. Solar cells charge replaceable, rechargeable batteries for powering the lights.
