引言随着世界经济的增长,电力需求迅速增加;同时,每人年均照明用电也在增加。有关资料表明, 美国的照明用电约占电力消耗的20%-25%,工业发达国家约为10%-20%,我国也已达到10%。因此,节约照明用电已成为各国政府关注的问题。在当今技术条件下,我国仍以石化燃料发电为主,所以增加发电就意味着增加环境污染,节约电能就意味着减少环境污染,因此,我国提倡节约照明用电具有重大的经济价值以及伴随的环保意义。
Introduction As the world economy grows, the demand for electricity increases rapidly; meanwhile, the annual electricity consumption per person is also increasing. Relevant data show that the United States accounts for about 20% -25% of electricity consumption in the lighting industry, about 10% -20% in industrialized countries and 10% in our country. Therefore, saving electricity for lighting has become a concern of governments of all countries. In today’s technical conditions, China is still dominated by fossil fuel power generation, so increasing power means increasing environmental pollution, saving energy means reducing environmental pollution, therefore, our country advocates the use of energy-saving lighting has a significant economic value and the accompanying Environmental significance.
