ABSTRACT:
An LED lighting device having heat convection and heat conduction effects has a heat dissipating assembly, a substrate, multiple LEDs and a base. The heat dissipating assembly has a housing and an outer cover. The housing has multiple air holes. The outer cover is mounted on an open top of the housing and has multiple through holes and an exterior flue protruding from the outer cover and extending into the housing. The substrate is mounted inside the housing against the outer cover and has a hole allowing the exterior flue to extend therethrough. The LEDs are mounted on the substrate and respectively correspond to the through holes. The base is attached to a bottom of the housing. The exterior flue encourages heated air to move through the exterior flue and flow out of the housing via the air holes. With such continuous and directional air movement, the LED lighting device obtains good heat-dissipating efficiency.
