Abstract
Abstract An imitation candle type of table lighting fixture contains one or more rechargeable batteries. While the lamp is in its holder, the battery is continously coupled to the small light bulb. The battery is recharged by removing the candle from the holder and plugging it into a recharging unit having a phone plug extending into a jack centered in the bottom of the candle. The insertion of the plug into the jack opens the light bulb circuit and forms a charging circuit through the rechargeable battery.
