Large Football Stadium Professional Luminaire

1.​ Luminaire power 1500W±3%, luminaire efficacy ≥130lm/W, total luminous flux ≥195000Lm, power factor ≥0.97; 5000K ≤ color temperature ≤ 6000K, color tolerance SDCM ≤5, color rendering index Ra ≥80, R9≥0, input voltage: AC220V/AC380V ±5%; frequency: 50Hz±2%. 2.​ The LED luminaire uses LED light sources with a lifespan of ≥120,000 hours, luminaire protection rating not lower than IP66, and impact resistance rating not lower than IK08. 3.​ Equipped with an independent optical-grade PC lens and spill light control function, effectively reducing illumination outside the field edges and minimizing light pollution to surrounding buildings. The optical lens adopts a prismatic design with a transmittance ≥96%, providing precise light distribution and effectively suppressing glare and stray light. 4.​ The luminaire features an external high-performance anti-glare reflector from the same manufacturer as the luminaire. It must maintain overall consistency with the luminaire in terms of appearance and color. The reflector uses anodized high-purity aluminum for high reflectivity and combines built-in reflective devices with external anti-glare components to effectively reduce spill light and glare, achieving excellent glare control.
