Ice Orchestra Lights Up with LEDs

We like to talk about applications of LEDs on Clearlysapphire. This might be one of the most unusual applications so far. The remote Swedish town of Luleå, near the Arctic Circle, features an orchestra with instruments made of ice and LEDs. Using an igloo that seats 170 people for an auditorium, the orchestra using ice instruments has been playing music for 15 years in Sweden and around the world.

American ex-patriot Tim Linhart makes each instrument in his back yard each year – from cellos and violas to an ice xylophone, guitars, congas and a banjo – out of ice.  The finely chiseled instruments take about a week each to build, but that’s not the hardest part of the process.  Being made of ice, you need to make sure that the instruments don’t melt when played. They are so fragile that even the heat from a player’s breath will make them out-of-tune.  And, of course, you need to play them in a suitably cold environment, an ice auditorium.

Linhart uses LEDs to light the instruments bringing an otherworldly feel to the concerts.  LEDs are a perfect medium for lighting the fragile instruments because they don’t emit heat along with light.  Traditional lighting would melt the instruments.

You can see the instruments with the LEDs and listen to a performance in this story from CNN.

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.
