Abstract

L'invention concerne les équipements d'éclairage et notamment la conception de lampes à diodes électroluminescentes à usage général. Le résultat technique consiste en une simplification de la conception et une amélioration d'évacuation de chaleur grâce à la possibilité de disposer différentes unités fonctionnelles sur une seule carte avec base métallique qui est disposée dans un plan commun formé par le corps et le dissipateur. Sur la carte on a monté des diodes électroluminescentes, une source d'alimentation et on a fixé un culot vissable. La base métallique de la plaque est utilisée comme conducteur électrique. L'échange de chaleur avec l'environnement s'effectue depuis l'intégralité de la surface du corps et du dissipateur.
