Baseball Under the Lights: How it All Got Started

 

Early Cincinatti Reds Night Game

Early Cincinnati Reds Night Game

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%.

Iconic Christ the Redeemer statue lit up in LEDs to celebrate the FIFA World Cup in Brazil

While the glitz and glamour of FIFA World Cup soccer remains on the field, others in Brazil are turning to LEDs to celebrate the tournament with light.  Even Brazil’s iconic Christ the Redeemer Statue is taking a role in the FIFA World Cup. The monument will be lit up with the colors of each country’s flag. This is possible due to a recent LED lighting retrofit of the popular tourist destination Rio de Janeiro, Brazil.

Completed in 1931, the famous statue had an LED light retrofit for its 80th birthday in 2011. Lighting company Osram replaced the outdated lighting system with 300 advanced LED projectors (from subsidiary Traxon Technologies).  These high-output spotlights are fitted with a special lens to precisely light the statue in alternating colors and different light intensities.

A special “Lighting Control Engine” aims each LED projector to light a particular part of the statue. The lighting can be programmed and controlled remotely providing energy efficient atmospheric lighting for the monument. The new lighting system saves time and resources for the Archdiocese of Rio de Janeiro.

Cities Worldwide Tap LEDs to Make Skylines Sparkle

The world’s skylines are changing. They’re no longer bathed in white light or neon. Thanks to new programmable LEDs, today’s city skylines are transformed into rainbows of light promoting good causes, events and company brands in every color imaginable that can change nightly.

But first let’s take a look at how lighting in cities got its start. Skylines and exhibitions played an early role in promoting lighting. Perhaps one of the most notable points in the history of lighting is the Chicago World’s Fair in 1893.

The Chicago World’s Fair in 1893 set the stage for promoting the wonder of electric lighting. In fact it was a big part in the race to light the world between Westinghouse backing Nicola Tesla (inventor of alternating current) and General Electric, owned by JP Morgan and Thomas Edison (inventor of light bulbs and direct current).

Westinghouse outbid Edison for the contract to light and power the fair. More than 200,000 white incandescent bulbs, using Tesla’s polyphase alternating current system, amazed crowds as they lit up the world’s fair at night. How did they beat out Edison? They under-bid Edison and GE banned them from using Edison light bulbs in retaliation for losing the bid. To light the fair, Westinghouse and Tesla sidestepped Edison’s light bulb patents with a new double stopper light bulb.

Here’s a photo from the Chicago World’s Fair at night. Just imagine how impressive this display of light must have been to a population used to gas lights and candles.

Substrate Update: It’s All About Patterning & Large Diameter Wafers

yole_developpement_logoMarket research firm Yole Developpement recently published a new report on front-end manufacturing trends for LEDs. Their latest report gives us some very good news about the sapphire market. Semiconductor Today reported on Yole’s analysis. Here are some big take-aways:

  • There is increased demand for larger-diameter sapphire wafers, with big players (such as LG, Sharp or Osram) moving to 6” wafers and Taiwanese players moving to 4” wafers.
  • LED chip makers demand more patterned sapphire substrates (PSS). PSS are now mainstream in the market with an 87% share as of Q1 2014.
  • While some companies (such as Soraa and Toshiba) have begun mass production of gallium nitride-on-silicon (GaN-on-Si) and GaN-on-GaN LEDs, market penetration of these alternative substrates will depend on future improvements in terms of performance and cost.  Without these improvements, alternative substrates will not be able to fully compete with sapphire-based LEDs.

What does this mean for sapphire makers? LED chip manufacturers are looking to gain production efficiencies, lower costs, and increase performance for their LEDs.  As the adoption for LED lighting increases, they need to make more and better performing LEDs. Large diameter sapphire wafers enable more throughput for each run of the MOCVD reactor, making better use of the reactor “real estate” and decreasing the cost per unit of area processed. Depending on the type of MOCVD reactor used, LED chip manufacturers using six-inch wafer platforms may achieve up to 48% greater usable area per reactor run as compared to two-inch wafers.

What does PSS offer? First, PSS helps improve epitaxial growth by promoting growth of the GaN in parallel to the substrate surface. This helps reduce the number of dislocations, called the dislocation density, which can degrade performance of an LED.  Secondly, patterning can help extract as much as 30 percent more light from an LED.  This is particularly advantageous for high brightness LEDs (HB LEDs) that are used in LED lighting applications.

LED chip manufacturers have been buying smaller 2-inch and 4-inch PSS from outside suppliers for years.  The next step in the evolution in the market is the migration to large diameter PSS. Already a pioneer in the development of large diameter sapphire substrates, Rubicon Technology has developed capabilities for large diameter PSS making it possible to manufacture 6-inch and even 8-inch PSS. Rubicon is already gaining traction in the PSS market.  The company recently reported in their Q1 2014 earnings call that they received their first order for PSS and have samples out to more than a dozen LED chip manufacturers.

Have LED Light Bulb Questions? Infographics & Such to “Enlighten”

Angie's List Infographic - LEDs

Angie’s List Infographic – LEDs

A lot of companies are participating in the new LED light bulb market, also called Solid State Lighting or SSL. These companies can be LED light bulb makers or participate by making some component of the LED light bulb ranging from heat sinks and LED chips to the sapphire growers, polishers and fabricators that make the foundation of the LED, the sapphire chip. All of them have a vested interest in helping consumers understand LED light bulbs and why they are different from CFLs and traditional incandescent light bulbs. We’ve gathered together some resources to help consumers understand their lighting options.

The US Department of Energy is leading the effort to educate consumers about their new lighting options and have enlisted companies that participate in the LED lighting market to help. The DOE has developed some very good resources on their own web site for the industry, http://www1.eere.energy.gov/buildings/ssl/. But they’ve also developed resources for consumers to learn more about their lighting choices. Some sample resources for consumers to learn more about LED lighting include a good FAQ here, http://energy.gov/articles/askenergysaver-led-lights.

The Federal Trade Commission requires a new lighting label, Lighting Facts, on all light bulb packages to help consumers understand what they’re buying. Optical and lighting publication Novus Light Today wrote about these new labeling requirements featuring an infographic from light bulb manufacturer Cree.

LED Spotlight: Cathedral Notre-Dame de Paris Goes LED

notre dame paris cathedral photos LED 11

Recently, a familiar European landmark got an illuminating facelift: Cathedral Notre-Dame de Paris. The famous 13th century gothic cathedral was retrofitted with a new LED lighting system by Philips, designed by Benoit Ferré, the resident bishop’s architect (European Architecture Company, EUROGIP). The project used a total of more than 400 luminaires with an installed capacity of just 30 kW, compared with almost 140 kW previously – reducing energy consumption by 80 percent.

The 400 luminaires are controlled by an easy-to-use touch-pad operated computerized system.  The system contains several lighting programs that can change the lighting due to the requirements of the day and Notre-Dame’s manager can add more if required. Almost all of the luminaires are dimmable, making it possible to modify the lighting according to the event taking place (ceremonies, concerts, prayers, etc.), the time of day, or the season.

The new lighting highlights two key works of art:

The Virgin and Child — This statue, moved to Notre-Dame in 1818, is the most famous of the thirty-seven representations of the Virgin that the cathedral contains. The LED lighting, using profile spots, redefines the characters while at the same time shining a gentle light onto the sculpture and the white flowers laid out at her feet.

The north and south rose windows — Made in the 13th century, the windows symbolize the flowers of paradise. Positioned discretely above the north and south doors more than 50 meters from the windows, two 250W LED spotlights shine onto each rose window, revealing the delicacy of the sculptures. Since they are invisible, the lighting gives the impression that the stained-glass window itself is radiating light.

LEDs, Sleep and SAD –Innovations in Light

Philips Wake Up Light

Philips Wake Up Light

In the past, most people just bought light bulbs without a thought. It was simply about light. There weren’t many extra considerations. Today’s lighting purchase might be made with intelligent applications and even therapeutic reasons in mind, such as seasonal affective disorder (SAD).

Light can help prevent or lessen the symptoms of SAD. According to WebMD, as many as 3% of Americans can suffer from SAD in the winter. When people are exposed to less natural light they may develop depression and anxiety, oversleep, and even have difficulty concentrating. Some people who live in extreme areas that depend on artificial light during long winter months without sunlight can use artificial light derived from LED light bulbs for some SAD relief.

Until now, most SAD sufferers needed special light boxes for SAD-related light therapy. LEDs are a natural light therapy source. Light from almost all LEDs used for lighting, displays and even TVs tend to naturally skew towards the blue part of the spectrum. Blue light stimulates a photoreceptor in the eye that reduces the production of the hormone melatonin and helps people stay awake.

LED lighting companies have begun to leverage blue light for those with seasonal disorders and even sleep issues.

Philips tackled the issue of the lack of light during polar winter in a town in the Arctic, Longyearbyen, Svalbard, where they experience dark for four months straight. Longyearbyen is the northernmost town in the world with 2,000 inhabitants (outnumbered by 3,000 polar bears). For two months, 186 volunteers used the Philips Wake-up Light for a study.  Already proven to work in a number of independent clinical studies, the Philips Wake-up Light was used to help wake up the volunteers with gradually increasing LED light prior to the alarm.

After using the Philips Wake-up Light for six weeks during the polar winter, 87% of residents said that they wake up feeling more refreshed, alert and ready for the day. Philips reported that 98% of residents said they would continue to use the Philips Wake-up Light rather than their previous method of waking up.  You can see a video about the experiment here.

Philips also has designed Philips goLITE BLU to help stave off the winter blues. The goLITEBLU provides the right level of blue light to help regulate a body’s clock and improve mood and energy levels. It is more efficient than traditional white light boxes, producing more concentrated light in a considerably smaller form factor.

For those challenged to wake up without hitting the snooze button repeatedly, there’s the Philips HF3500/60 Wake-Up Light that leverages both music and light to wake you up.  Here’s a link to an entertaining review written by a snooze button addict from Gizmodo.

Lighting Science’s Awake and Alert LED lamp brings more blue light to help people stay awake, while the company’s Good Night light reduces the blue light to help people sleep. The company also has designed the Rhythm Downlight with an app that can keep a sleep schedule for shift workers, those in extra long nights in cold climates and even those in space. The app syncs up with a specially designed digital LED light bulb. When it’s time to begin waking, the bulb will emit more blue light to help you wake up. But when it’s time go to sleep, the percentage of blue light is reduced, turning on your melatonin so you can sleep.

Hollywood Streets Get LED Makeover

The recent project to replace Los Angeles street lights with LEDs has come with some unintended consequences. Making movies at night on the streets of LA may never be the same.  In the past, directors liked the look that LA’s high-pressure sodium street lights gave to their movies.  The old street-lighting would lend a gritty, dark, film-noir feel to movies filmed on the streets of LA.

Here’s an image of an LA street before LEDs and after:

Hollywood Street Lights, Before and After LEDs (Source, Los Angeles Bureau of Street Lighting)

Hollywood Street Lights, Before and After LEDs (Source, Los Angeles Bureau of Street Lighting)

According to Dave Kendricken in No Film School, filmmakers like Michael Mann specifically chose Los Angeles as the location for the movie Collateral (2004, starring Tom Cruise) because of the antique aura the street lights brought the film.  Collateral’s plot took place completely at night, so the feeling that the lighting gave the film was a prime concern for the director.

The project is important to the city for saving money and energy.  LA’s 140,000 new street lights, a combination of Cree, Hadco and Leotek lights, are projected to save LA about $7 million in electricity savings.  According to a press release, LA funded the project through a $40 million loan from the Los Angeles Department of Water and Power (LADWP) and a combination of rebate funds also from the LADWP a Street Lighting Maintenance Assessment Fund.

The city said the loan paid back through savings in energy and maintenance costs by over the next seven years. After the loan is repaid, LA will begin to save $10 million/year. The project in LA isn’t complete yet. And you can see a map of the project’s progress here.

But, what can filmmakers do to mimic the look of the old street lights in LA?  They can choose a new city, select a different part of LA that hasn’t been converted yet, or use digital techniques and/or lighting filters to change the look. LED street lights present a challenge for filmmakers, but they’re worthwhile for the planet.

Sochi Olympic Venues Light Up with LEDs

The Winter Olympics in Sochi, Russia begin in just a few weeks on February 7th with the Opening Ceremonies.  The buzz about the Olympics is only just beginning.  This week Clearlysapphire focuses on the lighting for the games. Unlike many Olympic cities, Russia’s Sochi had to start from scratch and build their entire Olympic infrastructure from scratch. This did allow organizers to focus on building green, including installing green lighting using standards developed by the Russian Federation.  In total 200 buildings were built according to these standards, the first applied to construction in Russia, for the Games.

Organizers selected LEDs for lighting several key venues including Fisht Olympic Stadium, Bolshoy Ice Dome, Shayba Arena, and the Iceberg Skating Palace.  We’ll focus on two of them here.

The Bolshoy Ice Dome, to be used for hockey, features an innovative aluminum roof studded with 38,000 LEDs. Inspired by an ice drop, the roof will light up at night in vibrant colors like this photo. The facility will seat 12,000 people and will be used for concerts and sporting events after the Olympics. Fact:  Bolshoy means “major” in Russian.
