Piranha LED, it is a kind of encapsulation, square, transparent resin encapsulation, the four pins, negative place there is a lack of foot of LED. Piranha is astigmatism type LED, light Angle is greater than 120 degrees, high luminous intensity, and can withstand the greater power. Automotive brake lights, turn signal with more. Old beauty usually call it eagle - eyeled (eagle eye LED). It is said that the leds just born immediately aroused the attention of all, the development trend of fierce, have this name like piranhas. Another argument because of its shape like piranhas in the amazon.
Piranha LED by people more and more attention, because it better than phi 5 mm LED to heat dissipation, large Angle, light failure is small, long service life. Piranha LED made lines are well suited for light, back light box and large font of light source.
Because line clearance light lamp is generally used as the city high-rise buildings, and the back light light boxes advertising screen and large font lights are placed high up, if the LED is not bright or dim, its maintenance is difficult. Due to the phi piranha LED heat dissipation good, ordinary LED 5 mm, its light failure is small, long service life, so use of time, also can save considerable maintenance costs.
Piranha LED also can be used as the car's brake lights, turn light and back light. Has an advantage because of piranha LED heat dissipation, so it can withstand current of 70 ~ 80 ma. On the exercise of cars, often of high and low volatile storage battery voltage, especially when using brake lights, current increases suddenly, but this kind of circumstance of piranha LED not too big effect, so it is widely used in automotive lighting.
The power to estimate
1, the static compaction pixels (such as spacing and the same spacing) : 16 * 16 * 8 real pixels in a single module maximum power consumption 8 * 3 * 0.02 = 7.68 16-16 pixels wide; 8 -- eight pixels high; 3 - each pixel by three way current; 0.02 to estimate the size of per current all the way.
Note: 2 r1g1b real pixel two red LED series only count all the way on a current.
2, static virtual pixels (such as spacing) 2 r1g1b: single module maximum power consumption of 16 * 8 * 4 * 0.02 = 10.24 16-16 pixels wide; 8 -- eight pixels high; 4 - each pixel by the 4 road current; 0.02 to estimate the size of per current all the way.
Note: 2 r1g1b virtual pixels in two separate each tubes to calculate all the current red leds.
3, scan realities (1 r1g1b) or (2 r1g1b) : to sweep P10 full-color four 16 * 16 module as an example of a single module maximum work consumption (16 * 16 * 3 * 0.03) / 4 = 10.24 16-16 pixels wide; 8 -- eight pixels high; 3 - each pixel road from 3 current; 0.02 - estimated each the size of all the current; 4 -- for 1/4 scan.
Note: 1 r1g1b real pixel count four leds in parallel along the current; Scanning board each power estimate the utilization rate of 80%.
