Abstract
(EN)
An LED lighting device includes a base (1), a combined LED light source (2),and a lamp cover (3). The combined LED light source (2) includes a heat dissipating body (21), and a flexible printed circuit board (PCB) (22) installed with LED beads (23). The flexible PCB (22) is fixed on the heat dissipating body (21) which is conical in shape. The shape of the flexible PCB (22) is corresponding to that of the expanded surface of the heat dissipating body (21). Theflexible PCB (22) installed with the LED beads (23) enwraps the conical heat dissipating body (21) with a heat conducting double-sided adhesive (24), thus aconical lighting body is obtained. The lighting device can uniformly emit light in 360 degrees, and the effect of heat dissipation is better.

L'invention porte sur un dispositif d'éclairage à diodes électroluminescentes, lequel dispositif comprend une base (1), une source de lumière à diodes électroluminescentes combinée (2), et un capot de lampe (3). La source de lumière à diodes électroluminescentes combinée (2) comprend un corps de dissipation de chaleur (21), et une carte de circuits imprimés souple (PCB) (22) sur laquelle sont installés des cordons de diodes électroluminescentes (23). La carte de circuits imprimés souple (22) est fixée sur le corps de dissipation de chaleur (21), qui est de forme conique. La forme de la carte de circuits imprimés souple (22) correspond à celle de la surface d'expansion du corps de dissipation de chaleur (21). La carte de circuits imprimés souple (22) sur laquelle sont installés les cordons de diodes électroluminescentes (23) renferme le corps de dissipation de chaleur conique (21) avec un adhésif double-face conduisant la chaleur (24), et, par conséquent, un corps d'éclairage conique est obtenu. Le dispositif d'éclairage peut émettre de la lumière de façon uniforme sur 360 degrés, et l'effet de dissipation de la chaleur est meilleur.
