Do you know the common problems of LED lamp beads?
LED is a recent energy-saving and environment-friendly light source. It is not only energy-saving and environment-friendly, but also has a service life of 100000 hours. It is a new light source advocated by the government and the country. It has been a long time since LED lamp beads came out in 1996. With the progress of science and technology, they are gradually improving the shortcomings of LED. Today, let's 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 works normally and whether the indicator light is on. If not, check whether the power supply is connected properly; Check whether the power cord of the lamp bead is well connected with the positive and negative poles of the power supply, and whether it is reversed. If the above problems exist, please connect them correctly.
How to distinguish the light-emitting color of braided LED light beads: in case of no power supply, it is recommended to prepare a 3V button battery to facilitate the selection at the time of purchase. The battery can be used to easily check what light the LED emits.
Voltage requirements for LED lamp beads: for nominal 3V LED lamp beads, in fact, different colors have different requirements for current. Yellow requires the lowest current, followed by red, green, white and blue. Excessive current will scorch the wick. Using 2.4V rechargeable battery, yellow is easy to burn, because even if the voltage is small, but the current is too large, it will still burn at will. When using the button battery, although the button battery voltage is 3V, the button battery discharge current is very small, so the 3V led beads will not be burned. Therefore, when using LED light beads, you should select the appropriate power supply, pay attention to the voltage and current. When selecting the 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!
Causes of leakage of LED light beads: the machine and equipment are not grounded, and the personnel do not wear electrostatic bracelets (they must have ropes). Improper electrostatic protection. Then, during the packaging process, the pad of the bonding line is biased, and finally, there is a hidden quality problem of the chip itself.

The most significant advantage of LED lamp bead: its great style advantage is color variability, which can meet the requirements of different customers for the diversification of the actual effects of light, and can customize the light source. The application of indoor space will not be limited by the specifications, further improving the designer's actual operation of indoor space for the application of light source.
The advantages of LED lamp beads are certainly more than their disadvantages, such as low power consumption, high brightness, bright colors, anti vibration, long service life (80000-100000 hours of normal lighting), cold light source and other advantages, which are truly "green lighting". I believe that the future led beads will develop better and better with the progress of the times!
