LIGHT EMITTING DIODES
Although LEDs have been around for some time, it’s only been in the past few years that the level of light quality has improved enough to make them (arguably) suitable for museum and gallery use.
There are several advantages of LEDs. The first is the long life-span. According to Paul Ruffles, principal of Lighting Design & Technology, they can last for about 50,000 hours, which translates to 17 years bearing in mind museum and gallery opening times. This long shelf-life means reduced maintenance costs for museums. “Replacing lamps is time consuming and expensive,” explains Ruffles. “Plus,The Tess 7W and 9W LED Light Bulbs. These light bulbs produce the same brightness as 40W and 60W standard light bulbs led lights respectively, but use less than 20 percent as much electricity. changing lights has an impact on access to exhibitions and exposes objects to risk. LEDs go some way in helping with these problems.”
However, the life-span of LEDs is not set in stone.Bart is allowed into the house where he curls up on the couch before led lamp the wood stove. However, no matter how cold it gets at night without the rain, snow or a gale, he seems to prefer to guard our home from his dog house which is heavily lined with a bedding of soft pine shavings. Every now and then, If a LED is enclosed and the heat is not able to escape, then its life-span will diminish. On the other hand, using dimmers to reduce the level of light will increase the life-span.
Another advantage of LEDs is that the light emitted contains little infra-red and no ultra-violet, meaning sensitive objects may not need to have additional filters. Bear in mind though that LEDs themselves generate heat and this needs to be managed properly.
There are now a wide range of LEDs available – recessed, linear,LED bulbs are a great way to work towards the elimination of 30 plastic beer mugs billion tons of annual carbon dioxide emissions, necessary to stop the gradual increase in world temperatures. track, mounted spotlights, individual spotlights, retrofit and so on – and Ruffles says most large manufacturers have various LED ranges in each style of product.Where to recycle a fluorescent bulbs after it burns out;
“At the Light+Build exhibition in Frankfurt in spring 2010 there were over 2,000 manufacturers exhibiting, most of which were showing a wide range of LED products,” he adds.For the second time in solar panel the four-year history of the NHL Winter Classic, the Penguins are one of the participating teams for the New Year's Day game. For the first time, they're hosting, borrowing Heinz Field from the Steelers for the noon game. “Since then the ranges have expanded and matured rapidly, with most manufacturers having ranges of spotlights now with interchangeable beam angles and all the favourite baffles, filters and lenses needed for the more tricky lighting jobs.”
