Features of the venue lighting fixtures:
Spotlights
1) High light intensity. The height of the stadium is very high, and it is necessary to emit a few million candelas of light to obtain the illumination requirements for TV broadcasts of major international competitions.
2) Light distribution and light distribution. When the stadium is illuminated, multiple lamps and beams meet and cooperate to achieve the lighting effect. After the fixture is installed and fixed on site, it not only needs to meet the illumination and uniformity requirements on the horizontal plane, the illumination and uniformity requirements on the vertical plane, but also control the incident angle of the light to not cause the glare of the player in the active position and the field of view. The level of influence is exerted without spilling into the audience.
3) Anti-glare structure. In addition to the light distribution design, the glare control of the luminaire relies on the opaque structure of the luminaire to reduce glare.
4) Good color rendering. For the venues where television broadcasts major international competitions, the light of the fixtures should be very good at reducing the color, and the color rendering index should be no less than 80. The color rendering index of major international competitions for HDTV broadcasts should be no less than 90.
5) Angle adjustment device. The luminaire shall have a flexible, accurate and reliable aiming adjustment device. During the installation of the luminaire, the aiming of the luminaire is the final step in the installation. Aiming at the lighting designer's target position, the design level of illumination and uniformity can be achieved.
6) The light class should be flat and long. The luminaire is usually mounted on the side of the illuminated area, and the projection angle of the beam is at an angle to the illuminated surface. Therefore, when the spot shape of the luminaire is circular, the spot projected into the illuminated area becomes a flat elliptical shape. Only the light shift of the luminaire is a flat shape, and the light spot projected onto the illuminated area will form a circle covering a larger area. This light-emitting flat lamp has a two-sided symmetrical or one-sided symmetrical type. A lamp with a circular shape of a spot is a rotationally symmetric type of light distribution, and is used less.
