Compared with conventional light sources, high-pressure sodium lamps with high luminous efficiency, low power consumption, long life, through the fog and strong and not attracting insects, etc., is the application of university physical education major stadium lighting.

Compared with the traditional lighting, high-pressure sodium lamps with a high luminous efficiency, low power consumption, long life, and fog capabilities and does not induce such as insects, is the country's colleges and universities teaching sports venues of lighting applications light source.

Compares with the traditional photosource, the high-pressured sodium lamp has the luminous efficiency high, consumes the electricity few, the life long, passes the fog ability strong and does not tempt merits and so on insect, is the present Our country University sports teaching facility applicatio
