2. Floodlights: Floodlights are high-power lighting fixtures, usually installed in fixed positions around the field or suspended on high mast lights. The light of floodlights can be focused on the field, providing strong illumination.

3. Track lights: Track lights are lighting fixtures installed on athletic tracks to illuminate the track. Track lights are usually rows of small bulbs that provide sufficient illumination without affecting the athletes' vision.

4. LED lights: LED lights are a new type of lighting fixture with the advantages of energy saving, environmental protection, and long service life. LED lights are increasingly used in sports venues and can be used for high mast lights, floodlights, track lights, and other applications.

5. Intelligent lights: Intelligent lights are lighting fixtures that can be controlled through an intelligent control system and can be adjusted according to different competition needs. Intelligent lights can automatically adjust according to factors such as the type, time, and atmosphere of the competition, providing the best lighting effect.
