There will be enough power from that power source to light up the LED without the need for a transistor. File is safe, passed Norton virus scan! It worked well for some time, then one of the bulb went off.
It also rectifies current, i.e. it is a one way "current valve" When LEDs are attached to the outputs of TTL or CMOS ICs with a resistor R in series (see section "IC driver circuit"), the LEDs are being driven in voltage.
This is just a LED lamp circuit that can be operated from the mains voltage.
