WIPO Patent Application WO/2011/160452
Kind Code:
A1
Abstract:
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.
