La présente invention concerne un agencement de module de lampe destiné à une lampe. L'agencement de module de lampe présente au moins une DEL (2) et au moins une platine (4), la ou les DEL (2) étant disposée(s) sur la ou les platine(s) (4). L'agencement de module de lampe présente également un élément de support (6) sur lequel est ou sont maintenue(s) la ou les platine(s), et un élément optique (8) destiné à agir optiquement sur une lumière émise par la ou les DEL (2). L'élément optique (8) est selon l'invention conçu en tant qu'élément de protection destiné à assurer la protection contre l'entrée en contact avec la ou les platine(s) (4). De cette manière, on obtient, notamment sans nécessiter la constitution d'un composant supplémentaire, une protection fiable contre l'entrée en contact accidentelle avec la ou les platine(s) ou la ou les DEL (2), incident qui pourrait entraîner un endommagement en raison d'une tension électrique élevée.
