Among low-power LEDs, LED piranhas are the brightest, so many people blindly compare brightness when choosing LED piranhas. However, experts know that choosing LED piranhas should not only focus on brightness, but also on parameter ratios, consistency, and chips. LED piranhas have extremely strict requirements for use and packaging technology due to their unique characteristics. So, what issues should we pay attention to when using piranha light beads?
When using the bracket, it should be cleaned thoroughly and the LED chip should be fixed in the bracket bowl. After drying, solder the two poles of the LED chip, and then select the corresponding mold particles according to the number of chips and the light emission angle. Fill the mold with glue, align the piranha bracket for soldering LED chips with the mold, and pour it into the mold. After drying the glue (using an oven), demold it. Then place it on the cutting die for testing and sorting.
The technical specifications of LED piranha beads are the same as those of LEDs packaged in other ways. When packaging multiple chips on a piranha stand, relevant thermal resistance should be considered to minimize thermal resistance and extend its service life. Due to the four legs of the piranha light bead, in order to install the LED piranha light bead on the printed circuit board, four holes should be left on it. Because the two electrodes of the LED are connected to four legs, the two legs are connected to one electrode.
During installation, confirm which two legs are positive and which two legs are negative, and then design the PCB. There are also various shapes of piranha packaging pellets, including a 3mm round head and a 5mm round head, as well as a concave flat head. According to the requirements of the light emission angle, various packaging mold LED piranha beads can be selected for application.
