Abstract
LED lighting devices and fabrication methods are provided. An LED lighting device includes a heat dissipation lamp cup including a hollow structure, a driving power supply casing socket configured within the heat dissipation lamp cup to form a ventilation gap between the driving power source casing and an inner wall of the heat dissipation lamp cup, and a lamp holder configured on top of the heat dissipation lamp cup. The lamp holder includes one or more sidewalls forming a ventilation channel passing through the lamp holder. The ventilation channel is connected to the ventilation gap for air circulation. The LED lighting device also includes a substrate configured on an outer surface of each of the one or more sidewalls of the lamp holder and a plurality of LED light sources mounted on the substrate.
