- Electric cars and LED streetlights to help Edinburg meet emissions targets – Herald Scotland: This week, the Edinburgh City Council began considering adoption of the Sustainable Energy Action Plan (SEAP) that aims to reduce carbon emissions 42 percent by 2020. One proposal put forward in the plan is the replacement of street and tenement stair lights with energy efficient LED systems.
- New branding at Great American Ball Park – WVXU Cincinnati: When the Cincinnati Reds return from spring training, they’ll find new signs at their home stadium, Great American Ball Park. The $1-2 million project was paid for by Great American Insurance Group and will replace three neon signs throughout the park with new LED signage. The LEDs will use less electricity and operation costs will be approximately 80 percent less than the current neon signs.
- UL researchers LED the way – Clare Herald: Researchers at the Circuits and System Research Center at University of Limerick have received $380,000 in funding from Enterprise Ireland to develop technology that will make LED light-bulbs programmable. The technology will allow homeowners to control the level, tone and even color of light emitted from an LED light-bulb. The research aims to develop ‘smarter’ digital control algorithms to allow for increased functionality, as well as significant savings in energy consumption.
- This Smart LED Jump Rope Flashes Stats in Front of Your Face – Gizmodo: Smart Rope, an LED-laden jump rope is putting a twist on fitness-tracking. Like a wearable, the jump rope tracks your movements and generates stats, but thanks to the LEDs embedded in the rope, it then displays your stats right in front of your eyes while you’re working out.
Major League Baseball will play its All-Star Game on July 15th. Baseball may be as American as apple pie, but many people may not realize that it wasn’t always played at night. In fact, before lighting, the stands for most MLB games during weekdays were empty since most baseball fans were at work. Lighting changed all that and turned the MLB into the behemoth sport it is today. Today, even kids play baseball under lights. Now, Major League Baseball is going through another revolution – LED lighting.
But first, let us take a look at how revolutionary lighting was to baseball. GE lighting engineer Robert J. Swackhamer successfully deployed an array of high-wattage lamps to light the railroad yards at night for a railroad. The lighting worked so well that Swackhamer convinced his bosses to test the arrays at General Electric Athletic Field in Lynn, Massachusetts.
On June 24, 1927, General Electric lit up the first night baseball game in history between Lynn and Salem using 72 flood lamps on five towers. Salem won 7-2 in front of a crowd that included players from the Boston Red Sox and the Washington Americans.
The GE executives were onto something. The progress was slow at first. It took GE three years to sign up a few minor league teams as customers. By 1935, GE finally hit the Major Leagues with the Cincinnati Reds. The first Major League night game took place at the Red’s Crosley Field on Friday, May 24, 1935. The Reds beat the Philadelphia Phillies 2-1 in front of a crowd of 20,000 people. Legendary Cincinnati announcer Red Barber said, “As soon as I saw the lights come on, I knew they were there to stay.” By 1941, 11 of the 16 Major League baseball fields installed GE lighting, including the New York Yankees and Brooklyn Dodgers.
Today, yesterday’s high-intensity-discharge (HID) metal halide lamp floodlights are beginning to be replaced with LED lighting. There are a lot of factors that make LED lighting attractive in to MLB and even NFL stadium management. It may be difficult to light the entire playing surface with traditional HID lighting. Lighting must be able to shine on second base or the 50 yard line requiring brighter and longer distance. LEDs shine brighter and can light longer distances making them more efficient. They are also more precise, so they can light up the playing surface and not blind spectators. LED lighting also lasts longer – 50,000 hours – reducing maintenance costs. They also light to full strength instantly.
Super Bowl XLVII in New Orleans was marred by a 34 minute delay at the Superdome. According to Entergy New Orleans, power to the lights was lost when sensing equipment detected abnormalities. Once the outage cause was discovered and power was restored, the HID floodlights required time to come back to full brightness, about 10 to 15 minutes. By contrast, LED lighting is instant on.
Major League Baseball stadiums have already made progress in switching to LED signage with most stadiums sporting LED scoreboards and/or ribbon lighting. The most notable LED scoreboards in baseball are the Detroit Tigers’ 6,096 square feet LED video panel at Comerica Field and the Seattle Mariners’ scoreboard that measures 56.7-feet high by 201.5-feet wide and covers 11,425 square feet. They’re beginning to make progress in switching to LED lighting for their facilities. Busch Stadium, where the St. Louis Cardinals play, began energy efficiency improvements soon after it opened in 2006. Facility management has replaced more than 1,000 traditional spotlights and floodlights with LED lamps to cut lighting power demand in several areas by 90%.
