The piranha led patch is a packaged, square, transparent resin package with four pins and a missing LED at the cathode. Piranha is an astigmatic type of LED with a light emitting angle of more than 120 degrees, high luminous intensity, and can withstand greater power. Vehicle brake lights/turn lights are used more often.
Packaging process:
The piranha LED package has its own particularities. The pedigree lamp beads should be selected first. According to each piranha pipe to put a few LED chips, you need to determine the shape and size of the sinking bowl in the Piranha bracket.
When using the bracket, it should be cleaned and the LED chip should be fixed in the bracket bowl. After the drying, the LED chip is welded at two poles, and then the corresponding die is selected according to the number of chips and the angle of light output. Fill the mold with glue, and insert the LED-supported piranha bracket into the mold. After the glue is dry (drying with oven), it can be demoulded. Then it is cut into the cutting ribs and cut, followed by testing and sorting. The piranha LED's technical specifications are the same as those of the other packaged LED's. For multiple chips packaged in a piranha bracket should consider the relevant thermal resistance, thermal resistance should be minimized to extend the service life.
Since the piranha LED has four legs, in order to install the piranha LED on a 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 communicate with one electrode. In the installation to confirm which two legs are positive, which two legs are negative, then PCB design.
The shape of the piranha-encapsulated mold is also varied. There are φ3mm round heads and φ5mm round heads, as well as concave-shaped flat head shapes. According to the requirements of the light angle, various package molds can be selected.
Piranha LED is 4 feet, two more than the average 5mmLED two feet, and the light emitting part of the 4 feet and the circuit board soldering place has a certain spacing, 4 foot design and leave a gap is to let the piranha LED The heat dissipation is much better than the average LED. The operating current that can be passed is larger. The maximum is 40-50MA. The general LED is 20MA, so it is higher than the average LED brightness.
The piranha LED has attracted more and more attention because it requires better heat dissipation, larger viewing angles, lower light attenuation, and longer life than φ5mm LEDs. The Piranha LED is ideally suited for use as a linear light, a backlit light box, and a light source in a large font slot.
Because the line lights are generally used as contour lights of high-rise buildings in cities, and the backlight light box advertising screen and large-size lighting are placed high, if the LED light is not bright or dark, its maintenance is very difficult. Because the piranha LED's heat dissipation is good, the ordinary LED with a relative diameter of 5mm has a small light decay and a long life, so it will take a long time, which can save considerable maintenance costs.
Piranha LED can also be used as a car brake light, turn signal, reversing light. Because the piranha LED has advantages in heat dissipation, it can withstand 70~80mA. In the exercise car, the voltage of the storage battery often fluctuates greatly, especially when the brake lamp is used, the current will suddenly increase, but this situation does not have much impact on the piranha LED, so it is widely used in automobiles. Lighting.
