12V - 40W Fluorescent Lamp

Lampu Neon 12 V - 40 W

If you don't satisfied with the 12VDC Fluorescent Lamp and wanna build the larger one, you can make this.

This 40W fluorescent lamp inverter allows you to run 40W fluorescent tubes from any 12V source capable of delivering 3A and can be used to light regular or blacklight tubes.

Notes

  1. Email Bart Milnes with questions, comments, etc.
  2. Wind L1/T1. You will need an AM antenna rod that is about 60mm (2.5 inches) long to wind T1/L1 on. T1/L1 are wound on the same core. Shrink a layer of heatshrink over the core to insulate it. Leave 50mm of wire at each end of the coils.
    Primary: Wind 60 turns of 1mm diameter enamelled copper wire on the first layer and put a layer of heatshrink over it.
    Feedback: Wind 13 turns of 0.4mm enamelled copper wire on the core and then heatshrink over that.
    Secondary: This coil has 450 turns of 0.4mm enamelled copper wire in three layers. Wind one layer and then heatshrink over it. Do the same for the next two.
    Transformer/Inductor Winding
  3. Calibrate/test the circuit. To calibrate/set up the circuit connect the 2.2 Ohm 1W resistor (R3) in series with the positive supply. Connect a 40W fluorescent tube to the high voltage ends of the transformer. Momentarily connect power. If the tube doesn't light immediately reverse the connections of L1. If the tube still doesn't work, check all connections. When you get the tube to light remove the 2.2 ohm resistor and the circuit is ready for use. You will not need R3 again.
  4. This circuit is designed for 220V lamps. It will work with 120V units just fine, but will shorten the life of the tube.

Jika Anda kurang puas dengan lampu neon 12 VDC dan ingin membuat yang dayanya lebih besar, Anda bisa membuat yang satu ini.

Inverter lampu neon 40 W ini bisa menyalakan lampu neon 40 W hanya dengan power suplai 12 V berarus 3 A, bisa neon biasa atau neon tabung hitam.

L1 = lilitan kawat tembaga
T1 = trafo/transformator

Bisa dicoba tuch lampu PLC-nya
