The first step in the manufacturing process of Led energy-saving lamps
The LED should have high brightness, the astigmatism brightness should be above 1200mcd, the angle should be 120 degrees, and the spotlight brightness should be above 20000mcd. The voltage is 3.0-3.6v and the current is 20mA. Generally, the feet of LED are very long. In order to facilitate welding, pre-cut the feet with needle-nosed pliers or oblique-nosed pliers, leaving a 3mm pin.
The second step of Led energy-saving lamp manufacturing process
Place the mounting surface of the circuit board upward and place the LED in the polarity direction. Note that the long leg is the positive pole and the short leg is the negative pole. The brim of the straw hat is flat, and the negative pole is the positive pole. Do not install it upside down, because the LED is unidirectional and the circuit uses a series circuit. As long as one lamp is installed backwards, the whole set of lamps will not light up.
The third step of Led energy-saving lamp manufacturing process
After the LED is installed, the circuit board can be soldered, with the soldering surface facing upward. The welding temperature should be controlled within 240 degrees, with 30W soldering iron and grounding wire, and the time should not exceed 2 seconds. After welding, repair long stitches with nail clippers. So the lamp board is assembled. Next, the power supply will be assembled, and the welding of the power supply will be easier. As shown in the figure below, the welding is successful. Because the space in the lamp cup is limited, the arrangement of parts should be reduced in size and easy to install. After the power supply and the lamp board are welded, the wiring test can be done. The test current is 14mA, which can meet the requirements. Be careful to insulate the power supply again. I use a heat-shrinkable tube, which is more convenient and safe.
Finally, the assembly is completed. Using the prepared AB glue diagram, place the power board and the lamp board on the edge of the lamp cup and press for a few minutes to cure the glue. Such a practical LED energy-saving lamp is made and can be used. Precautions in manufacturing: Because LED is very sensitive to static electricity, static electricity can easily damage LED, leading to LED performance degradation or reverse breakdown and short circuit. Therefore, when touching the LED, be sure to do a good job in electrostatic protection, wear an antistatic bracelet, use an antistatic soldering iron, and ground the common soldering iron. Conditional also need to use anti-static desk mat.
Having introduced so much, I believe everyone has a general understanding of the manufacturing process of led energy-saving lamps. In fact, it is not difficult to make so many beautiful led energy-saving lamps on the street. Bian Xiao has told you how to make led energy-saving lamps in the above article, and it will be easy for you to learn as long as you study hard. Among them, Bian Xiao also told you the matters needing attention in making led energy-saving lamps. As long as you pay attention, you can easily succeed.
