Светодиодная лампа GE остывает за счет "дыхания"

15 Май 2012

В последнее время новые светодиодные лампы появляются практически каждый день, но примечательно, что в рамках большинства новых продуктов инженеры стараются внедрять очень интересные достижения в области технологий. Новая светодиодная лампа GE, эквивалентная 100-ваттной лампочке накаливания, как раз и является одним из примеров передовых продуктов. Инженеры разработали интересный способ защиты лампы от перегрева - она "дышит". 

Светодиодные лампы могут быть очень горячими. Особенно это актуально для ярких ламп. Охлаждение LED было и является большой проблемой. Не так давно производители предлагали большие и неуклюжие лампы, которые охлаждались за счет механических вентиляторов. Подход компании GE к созданию своих светодиодных ламп Energy Smart является гораздо более высокотехнологичным и позволяет продукту, эквивалентному по уровню светового излучения 100-ваттной лампе накаливания, быть достаточно компактным, чтобы совпадать по размеру со стандартными бытовыми лампами для светильников.

Так называемое "дыхание" осуществляется при помощи встроенной в лампу диафрагмы, которая вибрирует и позволяет создавать поток холодного воздуха. Точно так же пульсирует поверхность динамика. Эта технология называется SynJet. Она была разработана специалистами компании Nuventix. Подобные системы будут использоваться в бытовой электронике и компьютерах, которые нуждаются в направленном охлаждении. Компания Nuventix сотрудничает с GE, чтобы создать миниатюрную версию светодиодной лампы.

St2.jpg
Лампа излучает 1600 люмен света и потребляет всего 27 Вт. Она имеет срок службы в 23 года при работе по три часа в день. Цветовая температура светодиодной лампы составляет 3000 Кельвин. То есть речь идет о белом цвете. Лампа поступит в продажу в 2013 году. Ее точная цена пока не установлена. По предварительным данным, новинка будет находиться в ценовом диапазоне $ 39 - $ 49, при этом стоимость будет снижаться с ростом объема массового производства.
