In order to further strengthen the construction of the school's sports infrastructure and provide teachers and students with a better learning and exercise environment, the school launched the sports stadium lighting facility renovation project in September this year. The original lighting of the venue uses traditional metal halide lamps. Due to the aging of the equipment, the light decay is significantly reduced, and the illuminance value of the venue is not up to standard; at the same time, there are serious glare, low color rendering, green light, poor lighting effect, and the light source is easy to damage, and the maintenance cost High, high power consumption, poor safety, not environmentally friendly and energy-saving, unable to meet the needs of daily use。

Main gymnasium

The main stadium of the stadium is a modern indoor basketball court, which can accommodate nearly 5000 people; the stadium adopts 38 200W CHZ lighting CHZ-HB21-200W series stadium lights, replacing the original 400W metal halide lights in a 1:1 ratio with hanging cloth The light method creates a professional and healthy light environment.

After renovation, the stadium illuminance reaches 850lx, and the illuminance uniformity reaches 0.84. It meets the III-level professional competition lighting standard HB21 stadium light. It has the advantages of high luminous efficiency and high CRI. The professional optical lens and anti-glare design minimize glare interference and ensure The lighting of the entire venue is bright and comfortable, helping the 2021 Zhejiang University Basketball League to come to a successful conclusion.

Track and field (soccer) field

The track and field (football) field contains a 400-meter standard track and an 11-a-side football field. According to the original facility conditions, the CHZ lighting technical team selected 32 CHZ-FL32-1000W stadium lights to replace the original 1500W traditional gold one-to-one. The halogen lamp has a pole height of 15 meters, the average illuminance of the venue is 243lx, and the uniformity of illuminance is 0.52. It meets the I-level fitness and amateur training lighting standards and creates lighting effects that exceed customer expectations.

Overall venue

Outdoor basketball court

This outdoor basketball court is divided into multiple venues, with lights on both sides of each venue, three 8m high poles on each side, and two sets of lamps on each pole. The previous 400W metal halide lamp has been used for a long time, the luminous efficiency is very low, it is prone to flicker, and the glare is still very serious, which greatly affects the comfort of training and competition and brings safety risks.

We adopted the professional CHZ-FL27-200W series of floodlights and a professional 60° light distribution, which greatly improved the lighting environment of the venue.
