In-line LED lamp bead manufacturers have summarized the following 5 elements to pay attention to when using the commonly used lamp beads. I hope it will help you when using in-line LED lamp beads!

1. Forming method of in-line led lamp beads

1. It needs to be 2 mm away from the colloid to bend the bracket.

2. The bracket forming needs to be completed before welding.

3. The forming of the bracket needs to ensure that the pins and spacing are consistent with the circuit board.

2. Pay attention to the bending and cutting of the LED lamp beads in-line

Because the design requires bending and cutting, when bending and cutting the LED, the position of the bending and cutting should be more than 3mm from the bottom surface of the gel. Bending should be done before welding. When using LED plug-in lights, the spacing between the holes of the pcb board should correspond to the spacing between the LED pins. When cutting feet, high voltage static electricity is generated due to the vibration and friction of the cutting machine, so the machine should be grounded reliably and anti-static work should be done well.

3. In-line LED lamp bead cleaning

Special care should be taken when cleaning the gel with chemicals, as some chemicals can damage the surface of the gel and cause discoloration such as trichloroethylene, acetone, etc. It can be wiped and impregnated with ethanol, and the time should not exceed 3 minutes at room temperature.

4. In-line LED lamp beads overcurrent protection

The overcurrent protection function is to connect the LED series protection resistor to make it work stably

The formula for calculating resistance value is: R=(VCC-VF)/IF

VCC is the power supply | voltage regulator, VF is the LED driving voltage, IF is the forward current

Five, in-line LED lamp beads welding conditions

Soldering iron welding: The temperature of the tip of the soldering iron (higher 30W) should not exceed 300 °C, the welding time should not exceed 3 seconds, and the welding position should be at least 2 mm away from the colloid.
