Easy-to-assemble integrated LED bulb lamp

Abstract

An easy-to-assemble integrated LED bulb lamp includes a lampshade, a bulb base, a lamp cap, an LED module, a driver IC, a resistor, a lampshade and a lamp cap that form a sealed cavity. The bulb base is installed to an opening of the lampshade to divide the sealed cavity into an upper compartment and a lower compartment; the LED module is installed in the upper compartment; and the LED module is partially inserted into the bulb base and connected to the driver IC in the bulb base. Since the driver IC and the LED module can be integrally fixed during the injection molding of the bulb base, therefore the actual assembling process only requires the step of soldering the solder point of the resistor, and the assembling process can be simplified significantly to increase productivity.
