Abstract

Abstract Translated from French L'invention concerne une matrice d'éléments électro-luminescents présentant chacun une tige conductrice (13), une rondelle isolante (12) et une rondelle conductrice (11), un composant (17) étant monté sur la face supérieure de la tige (13). Les éléments sont disposés dans des trous d'un substrat isolant (30) et sont reliés électriquement selon des lignes par des métallisations (22) de la face supérieure du substrat (30) et selon des colonnes par des métallisations (24) de la face inférieure (36) du substrat (30). Selon le procédé, les éléments sont introduits dans les trous (33) du substrat et sont solidarisés d'une part aux métallisations (22) et d'autre part aux métallisations (24). Une plaque 20 portant des cavités paraboliques réfléchissantes (21) est montée en butée sur le substrat 30 et est maintenu par coopération entre des ouvertures 41 prolongeant les cavités 21 et les rondelles conductrices 11. The invention relates to a matrix of electroluminescent elements each having a conductive rod (13), an insulating washer (12) and a conductive washer (11), a component (17) being mounted on the upper face of the rod ( 13). The elements are arranged in holes of an insulating substrate (30) and are electrically connected in lines by metallizations (22) of the upper face of the substrate (30) and in columns by metallizations (24) of the face bottom (36) of the substrate (30). According to the method, the elements are introduced into the holes (33) of the substrate and are joined on the one hand to the metallizations (22) and on the other hand to the metallizations (24). A plate 20 carrying reflective parabolic cavities (21) is mounted in abutment on the substrate 30 and is held by cooperation between openings 41 extending the cavities 21 and the conductive washers 11.
