Abstract

L'invention concerne un dispositif d'éclairage pour un dispositif réfrigérant, notamment un réfrigérateur, comportant au moins un corps transparent allongé (12, 14) et au moins une diode électroluminescente (DEL) (16, 18) placée sur une face (74, 76) du corps ou à proximité de cette dernière pour injecter dans le corps la lumière émise par la DEL. Une première surface partielle (70) de la surface du corps, s'étendant dans le sens longitudinal du corps, est conçue pour diffuser et/ou réfracter et/ou réfléchir la lumière injectée dans le corps de sorte qu'elle soit déviée en direction d'une deuxième surface partielle (72) du corps, opposée à la première surface partielle, et sorte du corps. Un contact assurant une bonne conduction thermique est réalisé entre la DEL (16, 18), sur son côté opposé au corps (12, 14), et un déflecteur (20,22) qui s'étend le long de la première surface partielle (70) en recouvrant sensiblement cette dernière.
