Converting a 220V LED Bulb to a 5V USB LED Bulb
Changed PCB Circuit:
The use of modifying the PCB circuit of the LED bulb. This possibly involved putting off or bypassing components designed for operation at 220V and configuring the circuit to clearly receive lower voltage input.
Changed LED Configuration:
In vicinity of the LEDs being linked in series for operation at 220V, you soldered them in parallel. This permits the LEDs to perform at a lower voltage, collectively with 5V from a USB strength supply.
Determined Voltage and modern-day necessities:
You calculated the perfect voltage and contemporary-day requirements for the LEDs to characteristic very well at 5V. This guarantees that the LEDs get hold of an appropriate amount of electricity with out being broken.
Used Resistors for present day regulation:
To govern the modern flowing via the LEDs and prevent them from being overdriven, you delivered resistors in series with every LED or the LED array. Those resistors limit the cutting-edge to a steady diploma.
Attached USB Cable:
Eventually, you attached a USB cable to the changed LED bulb, allowing it to be powered by using the usage of a 5V USB strength supply. The USB cable offers a accessible and broadly to be had electricity input for the bulb.
Through following these steps, you successfully tailor-made a 220V LED bulb to feature on 5V USB electricity, supplying a realistic and inexperienced lighting fixtures answer. Wonderful activity on the trade!
