“确定照度标准、节约照明用电”一文发表后,收到很多读者来信,现简答如下:1.新光源的研究和开发在国际上是受到普遍重视的,新的光效高、电耗省的光源在不断出现。既使是当前最富代表性的第三代光源高压钠灯也仍在不断出现新品种。我国对新光源的研究开发也一直比较出色。近年来又先后从荷兰、联邦德国、日本等国引进了一些新光源的生产线。可以相信,节能的新光源在我国的应用将迅速扩大。2.就目前来说,高压钠灯应是效益最显著的节能 After the publication of the article “Implementation of Illumination Standards and Saving Electricity for Lighting” received a lot of letters from readers, the following is a brief answer: 1. The research and development of new light sources have received widespread attention in the world, and the new light efficiency is high. Light sources of power consumption continue to emerge. Even the most representative third generation light source high pressure sodium lamp is still emerging new varieties. China’s research and development of new light sources have also been outstanding. In recent years, some new light source production lines have been introduced from the Netherlands, the Federal Republic of Germany, Japan and other countries. It can be believed that the application of energy-saving new light sources in China will rapidly expand. 2. For now, high-pressure sodium lamps should be the most significant energy-saving
