When the piranha lantern bead was just born, it immediately attracted everyone's attention, and its development tends to be as fierce as the piranha, hence its name. So how to extend the lifespan of piranha light bulbs? How to effectively extend the service life of piranha lamp beads is a topic worth discussing.

The quality selection of piranha light beads is a very important factor. Different packaging processes can have a significant impact on the quality of the product. The piranha lamp beads encapsulated with ordinary adhesive have a 76% reduction in light decay compared to those encapsulated with A-class low decay adhesive in the same aging environment. So, choosing a good packaging process to manufacture piranha light beads will greatly extend their service life.

1. Storage

In order to prevent moisture, piranha lamp beads should be stored in a dry and ventilated environment with a storage temperature of -40 ℃ -100 ℃ and a relative humidity below 85%. It is recommended to use the piranha lamp beads within 3 months of their original packaging conditions to prevent rusting of the bracket. After opening the packaging bag, 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 liquids for cleaning, as it may damage the surface of the piranha lamp bead resin and cause colloidal cracks. If necessary, immerse the piranha lamp bead in alcohol or fluorine at room temperature for cleaning within one minute.

3. Welding

During the welding process, do not apply any external pressure to the lamp body, otherwise internal cracks may appear, which will affect the internal gold wire connection and cause quality problems. Colloids must not be immersed in solder. When welding, there should be a gap of at least 2 millimeters between the welding point and the lower edge of the adhesive. After welding is completed, it is necessary to take three minutes to allow the piranha lamp beads to return from high temperature to room temperature. If using a soldering iron to solder linearly arranged piranha light beads on the same PCB, do not solder the same two pins at the same time. Please use a soldering iron with a power of 30W or less when soldering with a soldering iron.

4. Forming

Do not form during or after welding. If necessary, the forming must be completed before welding. Remember that any act of squeezing resin may damage the internal gold wires.
