Преимущества энергосберегающих лампочек

Содержимое наших кошельков тает все быстрее. Причем наступление на наши кошельки идет по всем направлениям: как продавцы мгновенно реагируют скачком цен на любые известия, так и правительство постоянно повышает цены на коммунальные услуги. Правда, повышение оплаты за электроэнергию идет довольно медленно, но можно не сомневаться, что «коммунальная реформа» свое возьмет. Да и сейчас за месяц набегает кругленькая сумма. Что же делать, как противостоять этому? Нельзя же в самом деле, рискуя зрением, вкрутить повсюду лампочки по 40 ватт?

Оказывается, можно! И даже не по 40, а по 15 или 20 ватт, причем без какой-либо потери освещенности. Энергосберегающие лампы потребляют энергии в 5 раз меньше, так что 15-ваттная лампа светит, как обычная в 75 ватт, а 20-ваттная — как в 100. Более того, вместо 1000 часов эксплуатации, на которые рассчитана обычная лампочка, энергосберегающая прослужит от 10000 часов. Это значит, ввинтив такую лампу, вам в течение нескольких лет не придется покупать новую.

Включаются энергосберегающие лампы, как обычные, поскольку они имеют тот же цоколь, вкручивающийся в стандартные патроны.

Обычные лампы накаливания очень неэкономичны: только 5% потребляемой энергии преобразуется в свет, а 95% — в тепло, так как вольфрамовая нить начинает светиться, только разогревшись до температуры 2500 градусов Кельвина. Компактные энергосберегающие лампы — это многократно изогнутые для уменьшения длины люминесцентные лампы. Свет в этих «холодных» лампах испускается атомами ртути при столкновении с электронами, возникающими в электрическом разряде, на создание которого и идет потребляемая энергия. Поскольку ртуть излучает в ультрафиолетовой области, внутренняя сторона поверхности лампы покрыта люминофором, преобразующим ультрафиолет в видимый свет. В зависимости от типа люминофора различные лампы излучают свет разных оттенков, он может быть теплым, или холодным, или ярко-белым — как пожелаете.

Встроенный пускорегулирующий аппарат обеспечивает мгновенное и без мерцаний загорание и ровное немигающее свечение. Он рассчитан на 500 тысяч включений, заведомо перекрывающих временной ресурс самой лампы. Со временем свечение может несколько ослабиться из-за старения люминофора, но это не идет ни в какое сравнение с ослаблением света у ламп накаливания, колба которых покрывается темным слоем распыленного вольфрама. Иногда к энергосберегающим лампам причисляют и галогенные. Это верно только отчасти. В некоторых типах ламп, где применяется технология IRC, внутренняя поверхность колбы покрыта специальным теплоотражающим веществом, благодаря чему для поддержания рабочей температуры нити накала расходуется на 30% меньше электроэнергии. Но главное отличие галогенных ламп от обычных ламп накаливания

В том, что они сохраняют яркость свечения на протяжении всего срока службы. Достигается это тем, что к газу, наполняющему колбу, добавляется галоген — он перехватывает испаряющийся вольфрам и возвращает его обратно нити. Галогенные лампы имеют и другие преимущества: кварцевая колба поглощает большую часть вредного ультрафиолетового излучения, а нанесение на ее поверхность окиси титана и кремния увеличивает срок службы до 4000 часов.

Компактные энергосберегающие лампы выпускаются разными фирмами: американской General Electric, немецкой Osram, английской Philips и т. д. Поэтому можно быть уверенным в надежной работе лампы. Правда, стоимость их может поначалу испугать: она гораздо выше, чем цена обычной лампочки. Однако поскольку они служат минимум в 10 раз дольше, то и стоимость лампочек накаливания, использованных за этот срок, будет сопоставимой.

А затраты на электроэнергию будут для энергосберегающих ламп меньше, так как мощность у них раз в пять меньше, чем у обычных ламп накаливания. Учтите еще лишние хлопоты из-за всегда несвоевременно перегоревших лампочек. Не лучше ли вместо того, чтобы закупать впрок десяток лампочек (где их хранить, чтобы не разбились, да и как не позабыть, где лежат, за 12-то лет! ) или платить за электричество на годы вперед, потратиться один раз на энергосберегающуюлампочку. И платить ежемесячно в 5 раз меньше, чтобы дальнейшее увеличение платы за электроэнергию было нам до лампочки!
