Abstract

Une lampe (100) comporte un substrat (110), un élément de dissipation de chaleur (150), un élément optique (130) et un élément de transfert de chaleur (190). L'élément optique, le substrat et l'élément de dissipation de chaleur sont empilés dans cet ordre. Un élément de l'élément de dissipation de chaleur et un élément de l'élément optique ou un élément de l'élément de dissipation de chaleur et un élément du substrat présentent des premiers côtés d'extrémité fixés l'un à l'autre par un mécanisme de fixation, et leurs autres côtés d'extrémité sont accrochés et fixés de sorte à empêcher les deux éléments d'être déplacés dans une direction les éloignant l'un de l'autre, l'élément de transfert de chaleur étant disposé entre un des premiers côtés d'extrémité et un des autres côtés d'extrémité constituant un point d'appui et un des premiers côtés d'extrémité constituant un point d'application de force.
