Abstract

L'invention concerne une lampe à semi-conducteur (1) qui est équipée d'un dissipateur de chaleur (2, 3) qui comporte une première partie (2) et une seconde partie (3) qui sont reliées entre elles par ajustement serré et qui définissent conjointement un espace de réception (10, 12) destiné à un circuit d'attaque (5), la première partie (2) comportant une zone d'insertion (8) destinée à être insérée dans la seconde partie (3) et constituée d'éléments élastiques (21) pouvant être pressés vers l'intérieur. L'invention est particulièrement applicable à des lampes de rattrapage, en particulier des lampes de rattrapage pour lampes à incandescence et pour lampes halogènes.
