Stadiums Move to LED Lighting

　　LED的改進(jìn)能力，再加上更低的成本，打開(kāi)了戶(hù)外照明的大機(jī)會(huì)，特別是體育場(chǎng)照明。在這些應(yīng)用中，LED可以提供更明亮，更均勻的光，以及更多的照明選項(xiàng)相比，傳統(tǒng)光源。采用的三大因素是節(jié)約能源，降低維護(hù)成本，照明美學(xué)。

　　體育場(chǎng)是真的在移動(dòng)到LED照明方面的最后抵抗市場(chǎng)，主要是因?yàn)檫@些應(yīng)用需要高強(qiáng)度的光–多達(dá)100000流明每夾具。即使街道照明只需要10000至20000流明每夾具。

　　兩個(gè)最大的驅(qū)動(dòng)程序采用戶(hù)外LED照明是體育賽事和現(xiàn)場(chǎng)音樂(lè)會(huì)。“我們?cè)谝c(diǎn)，在LED方面的一些有利的技術(shù)只有一年或兩年老所以你現(xiàn)在開(kāi)始看到主要的玩家開(kāi)始采用它，”P(pán)aul Scheidt說(shuō)，產(chǎn)品營(yíng)銷(xiāo)，領(lǐng)先的LED組件，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.
