缺电无电地区的未来照明──太阳能电灯

Lighting for Unelectrified Areas in Future──solar Power Lamp

目前，尚有不少常规能源难以运送、架设电网也很不经济的无电缺电地区。这些地区往往人口分散，交通不便，文化水平不高，照明条件很差。本文主要讨论这类地区的未来照明问题。 这些地区的照明要求分散的独立电源供电，一次能源最好能就地取材，照明装置（连同供电电源）性能可靠，使用方便，且价格便宜，据此，经过技术经济分析，提出由小功率阳光发电系统供电的阳光电灯将是这类地区未来照明的最佳选择。

Nowadays, there are many remote areas without or hardly any of power supply in our country, where it is very expensive or impractical to tie in an electric grid directly and transport fuel for generating electricity. Lighting condition is very poor there because of sparsepoputation and poor transport facitities. The lighting for scuh areas in future is presented in this paper. Lighting there needs to be supptied hy stand-alone power system. The Lighting device (including power supply) must be highly retiable, easy to operate and cheap in price. According to analysis on technology and cost of the device, the option of the lighting for such areas in futurewill be the solar power lamp supplied by small photovoltaic power generation system.
