LED is a recent energy-saving and environmentally friendly light source. It is not only energy-saving and environmentally friendly, but also has a service life of 100,000 hours. It is a new type of light source advocated by the government. It has been a long time since the introduction of LED lamp beads in 1996. With the advancement of technology, the shortcomings of LEDs are gradually being improved. Today we will talk about some common problems of LED lamp beads, and how to deal with them. .

Problems caused by abnormal power supply: Check whether the power supply is working normally, and whether the indicator light is on. If not, please check whether the power supply is connected well; check whether the power cord of the lamp bead is the same as the positive and negative of the power supply. The pole is connected well, whether there is inversion, if the above problems exist, please connect it correctly.

How to divide the light-emitting color of the LED lamp beads: In the case of no power, if you want to choose conveniently when purchasing, it is recommended to prepare a 3V button battery, which can be used to easily check what light the LED emits when choosing.

The voltage requirements of LED lamp beads: LED lamp beads with a nominal 3V, in fact, different colors have different requirements for current, yellow requires the smallest current, followed by red, green, white, and blue. Too much current will burn the wick. Using a 2.4V rechargeable battery, the yellow color is easy to burn, because even if the voltage is not large, but the current is too large, it will still burn at will. When using a button battery, because the button battery voltage is 3V, but because the button battery discharge current is very small, the 3V LED lamp beads will not be burned. Therefore, when using LED lamp beads, you should choose a suitable power supply, pay attention to voltage and current. When choosing a power supply, if it does not meet the rated requirements of the LED lamp beads, the circuit needs to be improved, and the common resistance is added!

The reason for the leakage of LED lamp beads: The machine equipment is not grounded, and the personnel do not wear electrostatic wristbands (must be corded). Improper electrostatic protection. Then there is the packaging process, the welding wire PAD is biased, and finally the hidden quality problem of the chip itself.
