Abstract:
The present invention relates to a bulb-shaped LED lighting device that: includes plural LEDs using a polygonal metal substrate (metal PCB) and enables efficient heat radiation by integrating a heat-sink device with an LED-mounting unit supporting the metal PCB. The heat-sink device includes: a body that is installed between an LED package into which the plural LEDs are integrated and a screw cap which applies electric power to the LED package; and plural heat-sink pins that are extended in a radial direction on the outer circumference and are distanced from each other along the length of the body. At least one air passage is formed along the length of the body and passes through the heat-sink pins in the same location. Therefore, the heat-sink pins radiate the heat that is conducted from the LED package to the body, through an air-cooling method using the convection of external air.
