The power supply is extremely important and is quite complicated in a Phyllo since there are so many PCB as well as several voltages needed.
Capacitor reliant power supply
We have 79 LEDs working under 600mA which sums to 48A. As we flash 30 times every second and each flash lasts around 100us, the LEDs are on at most 0,3% of the time. Thus the average power supply needed is 0,16A.
We have decided to rely on capacitors to fully provide the LED power supply. There are two main reasons for this choice. First, the LED are switched off most of the time.… Read more
