How to effectively prolong the service life of piranha lamp beads is a question worth talking about. The choice of the quality of LED lights is a very important factor. And different packaging processes will have a considerable impact on the quality of the product. The LED lamp packaged with ordinary primer has 76% less light decay than the LED lamp packaged with Class A low-decay glue under the same aging environment. Therefore, choosing an LED lamp made with a good packaging process will greatly extend its service life.
1. Storage
In order to prevent moisture, piranha lamp beads should be stored in a dry and ventilated environment, the storage temperature is -40℃-+100℃, and the relative humidity is below 85%. It is best to use up the piranha lamp bead within 3 months in its original packaging condition to avoid rusting of the bracket. When the LED packaging bag is opened, it should be used up as soon as possible. At this time, the storage temperature is 5℃-30℃, and the relative humidity is below 60%.
2. Cleaning
Do not use unknown chemical liquid to clean the piranha lamp beads, because that may damage the resin surface of the piranha lamp beads, or even cause colloid cracks. If necessary, please immerse the piranha lamp beads in alcohol or freon at room temperature for cleaning. , within one minute.
3. Forming
Do not form during or after welding, if necessary, forming must be done before welding. Remember that any act of squeezing the resin may damage the gold wire inside the piranha lamp bead.
4. Welding
During the welding process, do not apply any external pressure to the lamp body, otherwise cracks may appear inside the piranha lamp beads, which will affect the internal gold wire connection and cause quality problems. The colloid must not be immersed in the solder. When soldering, there should be a gap of at least 2 mm between the soldering point and the lower edge of the colloid. After the soldering is completed, it is necessary to use three minutes to return the LED from the high temperature state to the normal temperature. If you use a soldering iron to solder linearly arranged LEDs on the same PCB, do not solder two pins of the same LED at the same time. Soldering iron below 30W is required for soldering.
