Sport Lighting:Modern sport lighting systems integrate advanced technologies to optimize visibility, safety, and energy efficiency. Professional venues require 300–2,000 lux illuminance (depending on sport and broadcast needs) with UGR <19 to minimize glare. LED fixtures (120–150 lm/W efficacy) dominate due to their 60,000-hour lifespan and 50% energy savings over traditional HID lamps. Key design elements include:
Adaptive Controls: Zonal dimming, motion sensors, and daylight harvesting.
Optical Precision: Asymmetric beam angles (Type III/IV) ensure uniform light distribution (≤1.5:1 uniformity).
Durability: IP65+/IK10 ratings for weather/impact resistance.
Poultry Lighting:Modern poultry lighting systems enhance productivity, animal welfare, and energy efficiency. LED technology dominates, offering tunable spectra (2,700–6,500K) to mimic natural cycles. Key parameters:
Broilers: 20–40 lux (first week) → 5–10 lux (maturity) to reduce aggression.
Layers: 14–16h photoperiods with 15–20 lux intensity for peak egg production.
Chick Health: UV-A (315–400nm) at 0.5–1.0 W/m² boosts vitamin D synthesis.
Smart systems feature:
Dawn/Dusk Simulation: 30-minute ramping to prevent stress.
Circadian Programming: Adjustable blue (470nm) for daytime alertness, red (660nm) for nighttime calm.
