Definitions

  • the inventive method includes: providing a set of mounting holes through the circuit board and a set of alignment holes in the circuit board; providing a set of mounting holes through the one-piece lensing member and a set of alignment protrusions extending from a circuit-board-adjacent surface of the lensing member; providing first and second sets of fastener-receiving cavities in the heat-conductive structure and open at the mounting surface thereof; mounting the circuit board to the mounting surface by inserting a first set of fasteners through the circuit-board mounting holes into the first set of fastener-receiving cavities; aligning the lensing member with respect to the circuit board by mating engagement of the alignment protrusions with the alignment holes; and installing the lensing member over the circuit board by inserting a second set of fasteners through the lensing-member mounting holes into the second set of fastener-receiving cavities.

Abstract

L'invention concerne un appareil d'éclairage à DEL (10) qui comprend (1) une pluralité de lentilles primaires (32) disposées chacune sur une matrice de DEL correspondante parmi des matrices de DEL (31) espacées sur une carte de circuit imprimé (30). L'appareil d'éclairage comprend également (2) un élément à lentilles d'une seule pièce (40) placé sur la carte de circuit imprimé et ayant une pluralité de lentilles secondaires (41) chacune placées sur l'une des lentilles primaires, à une certaine distance de celle-ci, sur la carte de circuit imprimé, la carte de circuit imprimé et l'élément à lentilles présentant des premier et second éléments conjugués positionnés et conçus pour s'emboîter mutuellement afin de permettre un alignement de haute précision des lentilles. La carte de circuit imprimé et l'élément à lentilles d'une seule pièce sont chacun reliés à une surface de montage (23) d'un élément conducteur de chaleur (20), et un tel assemblage, bien qu'il facilite un montage à haut rendement, n'empêche pas un alignement de haute précision des lentilles.
