Description

Technical Field

[0001] The utility model relates to an LED bulb lamp, in particular to a clamping type LED bulb lamp. Background Art

[0002] The assembly process of the existing LED bulb lamp is as follows. First step, assemble the power supply sleeve and the heat sink. Insert the power supply sleeve into the heat sink and use screws to connect and fix the power supply sleeve and the heat sink inside the power supply sleeve. Second step, insert the power supply into the power supply sleeve of the heat sink and lead out the wire at the power output end. Third step, assemble the PCB board. After aligning the tested PCB board with the screw holes, use screws to connect and fix the PCB board and the PCB heat conduction panel of the heat sink. Fourth step, assemble the lamp cap and wire. Fix one wire at the power output end on the rivet of the lamp cap, press it tightly, wind the other wire around the threaded part of the power supply sleeve, then tighten the screw shell, install the lamp shell, and the assembly is completed. From the above assembly process, it can be seen that the PCB board is a flat plate, which is inconvenient to install, and the positioning and fixation of the whole structure are mainly realized by screws, resulting in slow assembly speed and low assembly efficiency.
