Title
(EN) LED LUMINAIRE
(FR) LUMINAIRE À DEL
Abstract
(EN) An LED luminaire has a luminaire housing, an LED light module, and an LED driver. The LED light module comprises at least one LED array, a first thermal interface, and at least two second thermal interfaces. The first thermal interface is removably attached to the second thermal interfaces. The first and second thermal interfaces have sufficient surface area so as to maintain the ambient temperature within the luminaire housing at a level below which LED longevity significantly degrades.
(FR) L'invention concerne un luminaire à DEL qui a un logement de luminaire, un module de lampes à DEL, et un pilote de DEL. Le module de lampes à DEL comprend au moins une matrice de DEL, une première interface thermique, et au moins deux secondes interfaces thermiques. La première interface thermique est fixée de manière amovible aux secondes interfaces thermiques. Les première et seconde interfaces thermiques ont une aire de surface suffisante pour maintenir la température ambiante dans le logement de luminaire à un niveau inférieure à celui où la longévité des DEL se dégrade significativement.
