Back to School with More LEDs

New LED Scoreboard at Allen High School, Allen, Texas

New LED Scoreboard at Allen High School, Allen, Texas

With most American students returning to school, we’ve put together a look at two schools that are taking advantage of LED lighting to save money and improve the learning environment.

Special Ed

LED lighting in special education classrooms creates a better learning environment.  The buzzing and flickering from fluorescent fixtures often bother or distract special education students.  Administrators from Cherokee Elementary School in Scottsdale, Arizona believe that LED light fixtures will help students focus more, particularly special education students.

With the help of MaxLite, Cherokee Elementary School replaced 69 2’x4’ fluorescent fixtures with 60 2’x2’ Direct Lit LED Flat Panels in four classrooms.  The move will save nearly 60 percent in energy consumption, plus reduce maintenance costs since the panels are designed to last 50,000 hours or up to 13 years.  In addition, the school received utility rebates for the energy conservation measures to help offset the cost of the lighting retrofit.

Extreme Stadium at Allen High School in Allen, Texas

Texans famously like their football, especially high school football.  Perhaps the most ambitious high school football stadium is in Allen, Texas.  Approved by voters in 2009, Allen High School set out to construct one of the largest high school football stadiums in the US.  Opening for the 2012 season, “Eagle Stadium” at the suburban Dallas high school features 18,000 seats (the band is 675 members alone), NaturalGrass Matrix turf, a 75-by-45 foot HD video scoreboard from Daktronics (that includes LEDs), a weight room, a press room and private boxes that rival some college football stadiums.  The new stadium worked, the Eagles were the 5A State Champions in 2012 with a record of 15 – 1.

About Beth

It seems like LEDs are in everything these days – backlighting everything from your mobile phone, Apple iPad and flat screen HDTV to traffic lights, light bulbs and even the kitchen sink. But, making LEDs is a complex process that begins with the creation of sapphire. Not the pretty blue gemstone, but large commercial crystals that can weigh as much as 400 lbs. Once these large sapphire crystals are grown into boules and cooled, they’re cut into cores, cut further into flat circular wafers, polished and then used to grow LEDs. About 85 percent of HB-LEDs (high brightness) are grown on sapphire. There’s not that much information out there about the process. This blog is meant to shed some light (excuse the pun) on sapphire, LEDs and the industry that is devoted to making our lives just a little brighter. In the months ahead, we’ll tackle some topics that will help you understand a little more about sapphire and LED industry. Here’s a sample of what we’ll cover in the coming months: • Growing sapphire • For a wafer, size matters • Quality - When sapphire wafers go bad • LED light bulbs • Market & myths • Interviews with industry shining stars • Reports from industry events • Current events in perspective Please join us each week to learn more about sapphire and the LED market. We look forward to seeing you.
