The Research on the Application of Two Kinds of Light Sources in the Training Venue for Physical Education of Universities

摘要

The energy efficiency experiment of electric light is implemented according to the lighting design of the physical training venues.In the experiment,the corresponding illumination,power and energy efficiency ratio of the commonly used high pressure sodium lamp and metal halide lamp which work under the voltage ranging from 187V to 234V are experimentally measured and the lighting effect characteristics of the two kinds of electric light sources compared,proving that the high pressure sodium light source should be employed in the training venue for physical education of universities.
