Excellent color rendering index

In order to achieve a good color TV broadcast effect, the lighting quality of the stadium is not only related to the illuminance, but also closely related to the color temperature and color rendering of the lighting source. Article 3.3.2 of my country's "Civil Building Lighting Design Standard" GBJ133-90 stipulates that the color rendering index Ra of general light sources for color TV broadcasting should not be less than 65. According to the requirements of CIE NO.83 and FIFA, the light source The correlated color temperature Tc is greater than 5000K and the light source color rendering index Ra is greater than or equal to 80 to achieve the best on-site lighting effects and color TV broadcast effects.(as shown in the above picture for clear contrast display)
