Abstract

L'invention, qui concerne un procédé d'assemblage d'une unité de sources de rayonnement et un appareil d'éclairage à LED comprenant cette unité, se rapporte aux techniques d'éclairage et peut être utilisée lors de la fabrication d'équipement d'éclairage pour l'éclairage général en extérieur ou intérieur. Le résultat technique de la présente invention consiste en une réduction de la déformation thermique du panneau optique, en une meilleure mise en œuvre industrielle, en une étanchéité et en un plus grand volume thermique. Le procédé est caractérisé en ce que, entre le panneau optique et la plaque de LED, on dispose une plaque d'isolation électrique élastique comportant un revêtement adhésif. Cette plaque d'isolation électrique élastique comprend des ouvertures pour recevoir des LED, et in utilise des éléments élastiques disposés entre le radiateur et le panneau optique en qualité de moyen pour pousser ladite plaque contre le radiateur.
