Abstract

Zuluftöffnungen im unteren Bereich der Leuchte sowie im Reflektor
und im Fall einer oberen Abdeckung, Abluftöffnungen an ihren Rändern.

Description

  • Bei hohen Umgebungstemperaturen der Lampen fällt ihr Lichtstrom stark ab. Die kritischsten Temperaturen enstehen in mehrlampigen Leuchten für starke Kompakt-Leuchtstofflampen.
  • Bei direkt/indirekt strahlenden Leuchten, die oben und unten offen sind ist ein kühlender Luftstrom durch Auftrieb von vorn herein gegeben.
  • Bei Indirektleuchten und direkt/indirekten, die unten lichtdurchlässig abgedeckt werden, sind besondere Maßnahmen erforderderlich. Davon ist hier die Rede.
  • In beiden Fällen erfordert eine gelegentliche obere Abdeckung weitere Maßnahmen.
