LED bulb light assembly steps

1。 The preparation procedure done, flat on the PCB working mesa, thermal conductive coating cloth and the blade will insulating thermal conductive paste coated on the PCB and led lights, heat transfer.

2。 Then with tweezers to pick up the led lamp bead on PCB, and soldering iron to the led lamp bead welding on the PCB.

3。 With test pen have a light test.

4。 Next, we need to assemble the power casing and heat dissipation body of lamps and lanterns. After power casing stabbing into the lamps and lanterns of the cooling body, use the screwdriver fixed power point and heat dissipation of cohesion.

5。 Then put in the power supply into the lamps and lanterns of heat dissipation power casing, red wire for & other; +” , the blue wire for & other; - ” And then lead to the output of the power supply wire.

6。 Insulating thermal conductive paste evenly coated to the PCB panel of lamps and lanterns of the cooling body, pay attention to don't let the paste plug screw holes.

7。 You can will PCBA ( The led lamp bead and PCB) Them together and heat dissipation. Light the through the test of PCBA aligned with screw holes, screws with good PCBA thermal conductivity and heat dissipation of PCB panel.

8。 Use soldering iron to the output of the power supply wire welding on the PCB cohesion power welding plate, pay attention to the difference between when welding & other; +” “ - ” Extremely.

9。 A wire on the power supply output side on the lamp holder of the rivets, and riveting pressure. Then put another wire around the power casing thread, and the lamp holder of the metal shell tight.

10。 With industrial alcohol wet cleaning brush after the PCBA exterior dirt and clean solder flux trace.

11。 At this moment to be seeking a second light test, good assemble PCBA and heat in the body into the lamp holder to check whether normal light.

12。 Finally, the PC cover embedded into the lumen of heat dissipation body of lamps and lanterns. Here, a led ball bubble lamp is assembled finished.
