Badminton, table tennis and other types of balls are multi-directional, multi-angle flighting in the air, players playing the balls are multi-angle, making multi-phase movement at different speeds, it is always a process of tracking, capturing and focused imaging between the human eyes and the badminton and table tennis. The process of playing the ball is the process of tracking the ball flight path and aerial positioning. For indoor badminton, table tennis, basketball, volleyball, tennis and other sports stadium lights. There are a number of lighting effect indicators should be reached. However, from the practical point of view in practical exercise, for the civil fitness indoor stadium with leisure and fitness, lighting quality level should not be adopt a unitary standard of rigid indicators. According to the investment situation, playing level of players etc. many other technical and economic factors, determined by the investment operators in a reasonable range. Meeting the use is practical, practical is good. A lot of stadium lighting cases of indoor badminton, table tennis, basketball, volleyball, tennis show that: indoor lighting of civil stadium with fitness function which grasping the following five aspects of lighting quality, lighting effects can reach a certain level, will be able to meet playing exercise requirements. Indoor stadium lights should be no glare. Once there is glare in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, multiple locations and different angles of stadium will produce glare. Players can only see a strong stimulation of light, but can not see the flying ball, produced dazzling or discomfort visual effects in the visual system. Indoor stadium lights should be no stroboscopic effect. At present, in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, the stadium lights widely used are metal halide lights, bar lights, ordinary high-power energy-saving lights and so on. They have varying degrees of stroboscopic and stroboscopic effect. Indoor stadium lights should be high color performance. Lights only are bright, it is also important that light should with color. Light is just the founder of the colorful world. The principle of visual physiology reveals that light energy acts on the human visual organs, not only in the visual perception system to produce bright sense, but also to produce a sense of color. In the bright visual state, the bright sense corresponds to the intensity of the light energy, and the color sense corresponds to the wavelength of the light energy. Indoor stadium lights should be the sun color. Sunlight radiated to the ground are mainly three parts of UV-light, visible light, infrared light. UV-light and infrared light are invisible to the human eye, the light that the human eye can see is visible spectrum. Indoor stadium lights should be energy saving. The economic and technical objectives that indoor stadium lights in badminton, table tennis, basketball, volleyball, tennis and other stadium lighting should pursued is to achieve the most bright, clear, true and comfortable lighting quality in the most reasonable investment in lighting fixtures and minimum lighting operating costs. In current, there are many lights can be used for indoor stadium lighting, such as J-series LED stadium lights in Hangzhou ZGSM, we have great advantages in price, technical performance, the number of lights used in stadium, lighting effects and so on. We are leading in the field of lighting.
