教室人工照明是保护学生视力重要条件之一。由于提高照度的同时,还需考虑降低能耗及节约经费等问题,如何最大限度的利用现有照明灯具的效率,是学校卫生工作必须考虑的现实问题。为此,近年来我们在青岛有关中学中进行了改进白炽灯照明灯具的试验。 Artificial classroom lighting is one of the important conditions to protect students’ eyesight. Due to the improvement of illumination, it is also necessary to consider such issues as reducing energy consumption and saving funds. How to make maximum use of the efficiency of existing lighting fixtures is a realistic problem that must be considered in school health work. To this end, in recent years, we have conducted experiments in schools in Qingdao to improve incandescent lighting.
