How to estimate LED piranha power supply?

 

1. Scanning real image (1R1G1B) or (2R1G1B): take P10 full-color four scan 16 * 16 module as an example, power consumption of single module (16 * 16 * 3 * 0.03)/4=10.24 16 -- 16 pixel width; 8 - 8 pixels high; 3 - Each pixel point has three currents; 0.02 - estimate the size of each current; 4 - 1/4 scan.

 

Note: 1R1G1B real pixel four LED tubes are connected in parallel to calculate one current; The estimated utilization rate of each power supply of the scanning board is 80%.

 

2. Static real pixels (equal spacing and unequal spacing are the same): 16 * 8 real pixel single module power consumption 16 * 8 * 3 * 0.02=7.68 16 -- 16 pixels wide; 8 - 8 pixels high; 3 - Each pixel point consists of three currents; 0.02 - estimate the size of each current.

 

Note: 2R1G1B real pixel two red LEDs connected in series only count as one current.

 

3. Static virtual pixel (equidistant) 2R1G1B: power consumption of single module 16 * 8 * 4 * 0.02=10.24 16 -- 16 pixels wide; 8 - 8 pixels high; 4 - Each pixel point consists of four currents; 0.02 - estimate the size of each current.

 

Note: 2R1G1B virtual pixel two red LEDs separate each lamp tube to calculate one current.
