Wie andere Halbleiterbauelemente bieten LEDs bei richtiger Anwendung eine lange Lebensdauer. Bei richtiger Auslegung halten diese Halbleiterbauelemente im Gegensatz zu herk\u00f6mmlichen UV-Lampen \u00fcber 40.000 Betriebsstunden. Herk\u00f6mmliche Lampen erzeugen Licht, indem sie einen Lichtbogen in einer Kammer mit ionisiertem Gas (typischerweise Quecksilber) erzeugen, um Atome anzuregen, die dann zerfallen und Photonen emittieren.  Dar\u00fcber hinaus hat die Europ\u00e4ische Kommission (EC) durch ihre RoHS-Richtlinien (Restriction on Hazardous Substances) den rasanten Fortschritt der UV-LED-F\u00e4higkeiten kontinuierlich \u00fcberwacht. Viele in der Branche gehen davon aus, dass die EU die Verwendung herk\u00f6mmlicher Lampen einschr\u00e4nken wird, wobei sie zun\u00e4chst mit kleineren Systemen beginnen und in den folgenden Jahren zu gr\u00f6\u00dferen Systemen \u00fcbergehen wird. Durch die Kombination der Energieerzeugung heutiger UV-LED-Lichtquellen und der richtigen Formulierung von UV-h\u00e4rtenden Harzen, Photoinitiatoren und Additiven ist es m\u00f6glich, die derzeitigen Prozessm\u00f6glichkeiten f\u00fcr eine Vielzahl von Anwendungen zu \u00fcbertreffen.<\/p>\n\n\n\n<p>UV-LEDs sind ein kleiner, aber wichtiger Teil einer UV-Lichtquelle, aber auch der Rest des Systems muss ber\u00fccksichtigt werden, wenn es um die Lebensdauer geht. Dazu geh\u00f6ren der interne Steuerschaltkreis plus das K\u00fchlsystem, um sicherzustellen, dass die LEDs innerhalb ihrer Betriebsspezifikationen bleiben, sowie das Geh\u00e4use zum Schutz der LEDs vor Umwelteinfl\u00fcssen. <\/p>\n\n\n\n<p>Die patentierten und propriet\u00e4ren Systeme von Phoseon nutzen W\u00e4rmemanagement, Versiegelungstechniken, optische Verbesserungen und Steuerschaltungen, um die Leistung zu maximieren, ohne die Lebensdauer zu beeintr\u00e4chtigen.<\/p>\n\n\n\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background\" href=\"https:\/\/discover.phoseon.com\/led-uv-systems-lifetime\" style=\"background-color:#633799\">Download LED Lifetime Technical Note<\/a><\/div>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\t<section class=\"section-header\">\n\t<div class=\"grid-container\">\n\t\t<div class=\"grid-x grid-margin-x\">\n\t\t\t<div class=\"cell small-12\">\n\t\t\t    <h2>Vorteile der UV-LED-Technologie <\/h2>\n\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"cell small-6 small-offset-3\">\n\t\t\t\t\t\t<hr \/>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"cell small-10 small-offset-1\">\n\t\t\t    \t\t\t    <p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-19256 size-full\" src=\"https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart.jpg\" alt=\"\" width=\"960\" height=\"540\" srcset=\"https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart.jpg 960w, https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart-300x169.jpg 300w, https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart-768x432.jpg 768w, https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart-16x9.jpg 16w, https:\/\/phoseon.com\/wp-content\/uploads\/2020\/12\/BenefitsChart-640x360.jpg 640w\" sizes=\"(max-width: 639px) 98vw, (max-width: 1199px) 64vw, 770px\" \/><\/p>\n<\/p>\n\t\t\t    \t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n\n<p><\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\t<section class=\"two-column-flex\">\n\t\t\t\t<div class=\"two-column-flex-container\">\n\t\t\t<div class=\"flex-item small-flex-item\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"LED-Stapel\" src=\"https:\/\/phoseon.com\/wp-content\/uploads\/2019\/01\/LED-Stack-2-640x321.jpg\" \/>\n\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<div class=\"flex-item large-flex-item\">\n\t\t\t\t\t\t\t\t\t<h2 class=\"two-column-cta-image-header\">Faktoren, die die LED-Lebensdauer beeinflussen<\/h2>\t\t\t\t\t\t\t\t\t<p class=\"two-column-cta-image-content\"><p>Zwei wichtige Faktoren, die die Lebensdauer von LEDs beeinflussen, sind Temperatur und Stromst\u00e4rke. Wenn LEDs Strom in Licht umwandeln, entsteht innerhalb des p-n-\u00dcbergangs W\u00e4rme, die als Sperrschichttemperatur bezeichnet wird. Damit eine Diode eine maximale Lebenserwartung erreicht, muss die Sperrschichttemperatur in einem sicheren Betriebsbereich bleiben. Die UV-Leistungsabgabe einer Diode steigt mit dem Eingangsstrom, nimmt aber mit der Sperrschichttemperatur ab. Bei einem beliebigen festen Eingangsstrom gilt: Je k\u00fchler die Sperrschichttemperatur bleibt, desto mehr UV-Leistung liefert die Diode.<\/p>\n<\/p>\t\t\t\t\t\t<a href=\"http:\/\/phoseon.com\/de\/contact-us\/\" target=\"\"\n\t\t\t\t\t\t\t class=\"button two-column-cta-image-button\">Kontakt<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/section>\n\n\n\n\n\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\t<section class=\"two-column-flex\">\n\t\t\t\t<div class=\"two-column-flex-container\">\n\t\t\t<div class=\"flex-item small-flex-item\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"Grafik, Phoseon Lifetest-Daten\" src=\"https:\/\/phoseon.com\/wp-content\/uploads\/2019\/01\/Graph_Phoseon_Lifetestdata.jpg\" \/>\n\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<div class=\"flex-item large-flex-item\">\n\t\t\t\t\t\t\t\t\t<h2 class=\"two-column-cta-image-header\">LED End of Life Eigenschaften<\/h2>\t\t\t\t\t\t\t\t\t<p class=\"two-column-cta-image-content\"><p>Der normale \"Ausfallmodus\" einer LED ist die allm\u00e4hliche Verschlechterung der Lichtleistung.

Phoseon-Lichtquellen sind so ausgelegt, dass sie eine L80-Lebensdauer (80% der urspr\u00fcnglichen Leistung) von mindestens 40.000 Stunden gew\u00e4hrleisten, aber es hat sich gezeigt, dass die L80-Lebensdauer bis zu 60.000 Stunden betr\u00e4gt.
