Stadiums Move to LED LighTIng
LED的改进能力，再加上更低的成本，打开了户外照明的大机会，特别是体育场照明。在这些应用中，LED可以提供更明亮，更均匀的光，以及更多的照明选项相比，传统光源。采用的三大因素是节约能源，降低维护成本，照明美学。
体育场是真的在移动到LED照明方面的最后抵抗市场，主要是因为这些应用需要高强度的光–多达100000流明每夹具。即使街道照明只需要10000至20000流明每夹具。
两个最大的驱动程序采用户外LED照明是体育赛事和现场音乐会。“我们在引爆点，在LED方面的一些有利的技术只有一年或两年老所以你现在开始看到主要的玩家开始采用它，”Paul Scheidt说，产品营销，领先的LED组件，Cree公司
However， the benefits are not just on the lighTIng side， including energy savings and lower maintenance costs. LEDs deliver better lighTIng for broadcast TV， improving the watching experience on high-definiTIon TVs， and providing better special effects such as slow-motion camera replays.
In addition to the broadcasting requirements， stadiums also are re-evaluating LEDs as a light source due to reliability concerns， said Ray Chock， senior director of business development at Lumileds. “When the lights went out at the 2012 Super Bowl for about 30 or 40 minutes stadium officials not only worried about a delay at one of the largest sporting events， but also the potential liabilities when lights are off for that long. Typically， traditional light sources need to cool off before you can restart them， unlike LEDs，” added Chock.
