ABSTRACT:
A bulb-type LED lamp includes a cooling structure, an LED module, a transparent shade and a lamp head. The cooling structure includes a thermally conductive plate and a plurality of cooling fins configured by being bended upwardly from a periphery of the thermally conductive plate, and each cooling fins are disposed by being interspaced to each other. The LED module is attached onto a bottom face of the thermally conductive plate. The transparent shade covers the LED module correspondingly and is connected fixedly to the thermally conductive plate. The lamp head is fitted and connected to each cooling fin and electrically connected to the LED module. Thereby, the thermal convection is enhanced and the cooling efficiency is further promoted.
