They utilize a high voltage charge to ionize a mercury gas mixture in the lamp creating a plasma that emits uv light.
Uv lamp input voltage.
For this circuit we will use 4 5v of power in order to light the uv led.
These capacitors maintain a constant voltage output to the lamp even when the input voltage varies and is the more efficient of the two.
A resistor is needed so that we can bias and limit the current so that the correct amount flows to the led.
Capacitive reactance ballasts overcome this problem by the use of capacitors connected in series with the lamps.
Since lamp voltages can exceed the safe measuring range of most meters a potential transformer pt is required.
This system requires a high voltage amperage power supply typically a magnetic ballast transformer with a high voltage capacitor bank.
Medium pressure uv lamps do not have a filament.
Input current to ballast 10 000 0 92 0 90 220 44 47 amps.
To power a uv led all we need is the right voltage and current.
A typical 100 1 ratio is normally used.
