7 things to pay attention to when applying LED lamp beads
LED lamp beads are a fragile semiconductor product, so we should be extra careful when using LED products. Today, we will summarize the precautions for the use of LED lamp beads. Please pay great attention to them in the process of using LED lamp beads later.
1. Attention should be paid to the folding angle of LED lamp beads
When the LED lamp bead is bent or folded, please do not get too close to the colloid, and keep a distance of more than 2mm from the colloid, otherwise the bracket in the LED lamp bead colloid will be separated from the gold wire, and the number of times of folding the corner at the same place cannot exceed three times , the corner is bent to 90°, and it is 1 time to return to the original position.
2. LED lamp bead welding temperature
The soldering temperature is around 260°C, the time is controlled within 5S, the soldering point is more than 2.5mm away from the bottom of the colloid, and the electric soldering iron must be grounded.
3. The temperature of the LED
It should be noted that the increase in temperature will reduce the internal resistance of the LED. When the external ambient temperature increases, the internal resistance of the LED light source will decrease. If a regulated power supply is used for power supply, the LED operating current will increase. When the rated operating current exceeds its rated operating current. , will affect the service life of the LED lamp bead, and will seriously "burn out" the LED light source. Therefore, it is best to use a constant current source to supply power to ensure that the working current of the LED lamp bead is not affected by the external temperature. LED temperature is also the most important factor affecting the life of LED lamp beads.
4, the sealing of LED lamp beads
As long as LED lamp beads are used outdoors, they are faced with the problem of moisture-proof sealing. If they are not handled properly, it will directly affect the service life of LED lamp beads. At present, a small number of manufacturers who have high requirements on the quality of LED lamp beads use the traditional epoxy resin "watering" method to seal the LED lamp beads. This method is more troublesome to operate and is not very suitable for larger LED lamp beads Fit, will also cause the weight of the product to increase.
5, LED lamp beads should use DC power supply
In order to reduce the product cost, some manufacturers use the "resistance-capacitor step-down" method to supply power to the LED lamp beads, which will directly affect the life of the LED lamp beads. Using a dedicated switching power supply (preferably a constant current source) to supply power to the LED lamp beads will not affect the service life of the product, but the product cost is relatively high.
6. The current of the LED lamp bead cannot exceed the IF current of the LED lamp bead
Overcurrent work will make the life of the LED lamp bead decrease quickly. If it exceeds the limit, the LED lamp bead will be burned out immediately.
Seven, LED lamp beads must take anti-static measures
In the process of processing and production of LED lamp beads, certain anti-static measures should be adopted, such as: the workbench should be grounded, workers should wear anti-static clothing, anti-static rings, and anti-static gloves, etc., if conditions permit, anti-static can be installed At the same time, it is necessary to ensure that the humidity of the workshop is about 65%, so as to prevent the air from being too dry to generate static electricity, especially green LEDs are relatively easy to be damaged by static electricity. In addition, the anti-static ability of LED lamp beads of different quality grades is also different, and the anti-static ability of LED lamp beads with high quality grades is stronger.
