With the development of led technology, led lamps are widely used in many fields. Led lamp is not only energy-saving and environment-friendly, but also has a long service life. At the same time, it is green without stroboscopic, which has a protective effect on vision and is convenient to install. In particular, led bulbs have become the most commonly used green light source for citizens. Mastering the assembly process of led bulbs can naturally make life more convenient. Bian Xiao will teach you how to assemble led bulbs today.

Led bulb lamp assembly tool

Heat-conducting varnished cloth blade, cross screwdriver, manual soldering table, electric soldering iron, assembly fixture frame, tweezers, test regulated power supply, wire stripper, art knife, industrial scissors, multimeter, cleaning brush, etc.

Assembly procedure of Led bulb lamp

Step 1: After the preparation process is completed, lay the PCB flat on the workbench, and then apply insulating thermal paste on the thermal conductive surfaces of the PCB and led lamp beads with the blade of thermal conductive coating cloth, as shown in the following figure.

Step 2: Then pick up the led lamp beads with tweezers and carefully put them on the PCB, and solder the led lamp beads to the PCB with a soldering iron.

Step 3: Test the lighting with a test pen.

Step 4: Next, we will assemble the sleeve of the power supply and the radiator of the lamp. After inserting the power sleeve into the radiator of the lamp, fix the connection point between the power sleeve and the radiator with a screwdriver.

Step 5: Then insert the power into the power sleeve of the radiator of the lamp, with the red line being "+"and the blue line being "-",and then lead out the lead at the power output end.

Step 6: Apply the insulating thermal conductive paste evenly on the PCB panel of the lamp radiator, and be careful not to let the paste block the screw holes.

Step 7: Next, you can assemble PCBA (namely led lamp bead and PCB board) and radiator. Align the PCBA that has passed the lighting test with the screw holes, and fix the PCBA and the PCB heat conduction plate of the radiator with screws.

Step 8: solder the output conductor of the power supply on the pad connected to the power supply on the PCB with a soldering iron, and pay attention to distinguish the "+"and "-"poles during welding.

Step 9: Place a wire at the power output end on the rivet of the lamp holder and press the rivet tightly. Then another thread is wound around the thread of the power sleeve to tighten the metal shell of the lamp holder.

Step 10: Wet the cleaning brush with industrial alcohol, and then clean the dirt on the surface of PCBA and the rosin traces at the solder joints.

Step 1 1: At this time, conduct the second lighting test, and insert the assembled PCBA and radiator into the lamp holder to see if the lighting is normal.

Step 12: Finally, insert the PC cover into the inner cavity of the lamp radiator. An led bulb lamp is assembled here.

Through the above introduction, have you learned to assemble led bulbs yourself? Everyone must remember to wear an electrostatic wrist to protect themselves during the operation.
