Title
(EN) LED LAMP ASSEMBLY
(FR) ENSEMBLE LAMPE À DIODES ÉLECTROLUMINESCENTES
Abstract
(EN)
A vehicle lamp assembly, comprising a lens, a monolithic lamp housing that cooperates with the lens to at least partially define a lamp chamber that is generally fluidly isolated from an ambient atmosphere, and the lamp chamber subdivided into at least three distinct cavities. At least one LED is provided in each of the at least three distinct cavities. The lamp housing further comprises a heat sink exposed to the ambient atmosphere outside the lamp housing. The heat sink is arranged so that heat generated by the LEDs in any one or more of the at least three cavities of the lamp chamber is dissipated to the ambient atmosphere.
(FR)
La présente invention concerne un ensemble lampe pour automobile, comprenant une lentille, un logement de lampe monolithique coopérant avec la lentille de façon à définir au moins en partie une chambre de lampe qui soit généralement fluidiquement isolée d'une atmosphère ambiante, la chambre de lampe se subdivisant en au moins trois cavités distinctes. Chacune des trois cavités distinctes est équipée d'au moins une diode électroluminescente. Le logement de lampe comporte en outre un dissipateur thermique exposé à l'atmosphère ambiante de l'extérieur du logement de lampe. Ce dissipateur thermique est organisé de façon que la chaleur produite par les diodes électroluminescentes dans l'une quelconque au moins des trois cavités de la chambre de lampe se dissipe dans l'atmosphère ambiante.
