The Safe bottle lamp, called sudeepa or sudipa for ''good lamp'', is a safer kerosene lamp designed by Wijaya Godakumbura of Sri Lanka. The safety comes from heavier glass, a secure screw-on metal lid, and two flat sides which prevent it from rolling if knocked over. ==History== As surgeon Dr. Godakumbura saw many burn cases caused by kerosene lamp fires. Over 1 million homes in Sri Lanka do not have electricity, and rely on kerosene lamps for illumination, often improvised lamps made from bottles. These tall lamps tip easily, and when they do, the wick holder often falls out and starts a sudden, intense fire. Often the fuel falls on a nearby person, setting them ablaze and resulting in severe burns, often fatal. In 1992, Dr. Godakumbura set out to design a new lamp that was both safer, and inexpensive enough to be affordable by the impoverished Sri Lankans at risk for these fires. The resulting lamp is a small, flattened sphere, which resists tipping and rolling. It is made of thick glass to resist breaking, and has a screw-on metal cap that holds the wick in place and prevents spilling. In 1993, with contributions from numerous sources, including Science Fiction writer and Sri Lanka resident Arthur C. Clarke, and the Canadian High Commission, the lamp was put into production. Available for a cost of less than US$0.25 each, over half a million of the new lamps have been sold, and Dr. Godakumbura hopes to continue producing the new lamps until use of improvised lamps drops to a small percentage of lamp use in Sri Lanka. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Safe bottle lamp」の詳細全文を読む スポンサード リンク
