Title (EN) ILLUMINATING DEVICE COMPRISING LIGHT-EMITTING DIODES
(FR) DISPOSITIF D'ÉCLAIRAGE À DIODES ÉLECTROLUMINESCENTES
Abstract: front page image
(EN)The invention relates to an illuminating device (1) comprising light-emitting diodes, said device being equipped with a heat dissipator comprising a radiator, characterized in that said heat dissipator comprises: a base (4), one of the sides of the base (4), called the illuminating side, bearing said light-emitting diodes, said illuminating side being intended to be directed downwards, and the other side of the base (4), called the heat transmitting side (7), making contact with the radiator (3); the radiator (3), consisting of a single-part element, comprising: a plate (31), one of the sides of the plate making contact with said heat transmitting side (7) of the base (4); and fins (32) extending around said plate (31), said fins (32) being oriented substantially perpendicular to said plate (31) in such a way as to allow the light-emitting diodes to be cooled by natural convection.
(FR)Dispositif d'éclairage (1) à diodes électroluminescentes équipé d'un dissipateur d'énergie thermique comprenant un radiateur caractérisé en ce que ledit dissipateur d'énergie thermique comprend : - un corps de base (4), l'une des faces du corps de base (4), dite face d'éclairage supportant lesdites diodes électroluminescentes, ladite face d'éclairage étant destinée à être dirigée vers le bas, l'autre face du corps de base (4), dite face de transmission (7) de chaleur étant en contact avec le radiateur (3), - le radiateur (3) constitué par un élément monobloc comprenant : - une plaque (31), l'une des faces de la plaque étant en contact avec ladite face (7) de transmission de chaleur du corps de base (4) - des ailettes (32) s 'étendant autour de ladite plaque (31), lesdites ailettes (32) étant orientées sensiblement perpendiculaires à ladite plaque (31) de telle façon à permettre le refroidissement des diodes électroluminescentes par convection naturelle.
