Abstract

L'invention concerne un châssis métallique de lampe à diodes électroluminescentes (DEL) comprenant de multiples bandes de substrat agencées parallèles. Chaque bande de substrat comprend un premier conducteur (1), un second conducteur (2) et un conducteur thermique (3). Des zones électroluminescentes (4) et des zones de dissipation de chaleur (5) sont disposées en alternance sur les bandes de substrat. Les premiers conducteurs (1) dans les zones électroluminescentes (4) sont en forme de L renversé dans des agencements symétriques. Les conducteurs thermiques (3) des zones de dissipation de chaleur (5) font saillie vers le bas. Dans le châssis métallique de lampe à DEL, les multiples bandes de substrat sont formées en même temps et les bandes de substrat sont directement connectées. Grâce à l'ajout des conducteurs thermiques, les performances de dissipation de chaleur sont améliorées.
