Abstract (en)
A 360-degree angle LED (light-emitting diode) illumination device (1) comprises a copper base plate (10), a plurality of LED chips (12), and a flexible PCB circuit layer (16). The copper base plate is electroplated with a layer of silver thereon. The plurality of LED chips is provided on the peripheries of the copper base plate. The flexible PCB circuit layer is provided on the peripheries of the copper base plate and electrically connected with the LED chips for controlling the LED chips. Accordingly, it is able to provide 360-degree angle illumination range and to improve the thermal conductivity and heat dissipation capability in order to prolong effectively the lifetime of the LED chips in use.
