A light emitting diode illumination device comprises: a heat-dissipating element, multiple fins, a diode luminous device, multiple heat-conducting elements and a cap element. The multiple fins extend from the surface of the heat-dissipating element. The multiple heat-conducting elements that set between the fins are closely adhibited the surface of the heat-dissipating element, the heat produced in operation by the light emitting diode illumination device is distributed uniformly on the heat-dissipating element and the fins by the effective heat exchange effect of the multiple heat-conducting elements and then dissipated. In addition, thereis a waterproof passage in the cap element so as to start a control circuit by passing a wire line into it. So the illumination device is suitable to the outdoor fixing.

L'invention concerne un dispositif d'éclairage à diodes électroluminescentes comprenant : un élément dissipant la chaleur, plusieurs ailettes, un dispositif lumineux à diodes, plusieurs éléments conducteurs de chaleur et un élément de fermeture. Les éléments conducteurs de chaleur se trouvant entre les ailettes se trouvent placés tout contre la surface de l'élément dissipant la chaleur, la chaleur produite en fonctionnement par le dispositif d'éclairage à diodes électroluminescentes étant répartie uniformément sur l'élément dissipant la chaleur et les ailette par un effet efficace d'échange thermique des éléments thermoconducteurs et ensuite dissipée. De plus, un passage étanche est formé dans l'élément de fermeture de façon à pouvoir exciter un circuit de commande en faisant passer un fil dans celui-ci. Ainsi, le dispositif d'éclairage est approprié pour être fixé à l'extérieur.
