Junk Workshop Spotlight

Working with emery constantly lacks light. Garage light cover the body and there is a shadow on the workpiece. Originally used as a carrier, even used a headlamp flashlight. I decided, nevertheless, to ease the task and make constant lighting. I looked for a ready solution. And, as always, I decided on my own production. In the role of a reflector I thought of using just a sheet of aluminum. I came to the opinion that we need directional light. So I will collect something like a searchlight.

We assemble a powerful searchlight for the workshop

And so, the reflector will be very simple. The houses had a fair amount of cases from the computer’s power supply. Folding the two halves, it turns out such a reflector.

I will fasten the halves of the cases to the case of the computer power supply. A power supply board will be placed in the PSU case.

The main element of the lighting device, of course, will be the LEDs. I took four 10 watt LEDs. The supply voltage is 12 volts each.

The main element, not the only one, will be the power supply board. I removed this card from an old inkjet printer or scanner, and I don’t remember. The output voltages of the power supply are two, 42 volts and 5 volts. From 42 volts I will power the LEDs by turning them on in series. From 5 volts I will power the fan, which is installed on the case of the used power supply unit.

I will replace the power switch with a toggle switch.

First you need to mark the holes for the LEDs. I still applied the aluminum sheet. Distilled and drilled holes. I also made a series of holes with which I fastened both the covers and the plate together.

Connecting the LEDs in series with medid not apply a current-limiting resistor. Since the voltage is 42 Volts, the current is correspondingly lower. I he was 0.5 Ampere. The voltage is well stabilized and does not walk.

Soldered the wires from the power supply board, after discharging the switch and the connector. Red and green at 42 Volts, plus and minus, respectively. Thin wires on the fan. From 5 volts the fan will spin slowly and without creating noise. I think the flow of air will be enough. On the power supply unit of the computer, the board was connected using a connector, the same connector is on my power supply board.

I will screw the power supply board onto the plastic, since the computer’s power supply's native openings have a large distance. Plastic by the size of the withdrawn power supply. Mark and drill holes.

I screw the plastic in the case. I screw the power supply board to the plate. Just set the toggle switch. In place of the old switch soldered wires. Spotlight for the workshop of trash
Solder the wires to the toggle switch.

I twist the body. I turn it on and check it. Everything works fine. You could certainly use a full-fledged power supply unit of the computer. I also had an old office equipment board that I wouldn’t use anywhere.

That such a searchlight turned out. I will probably fix it on neodymium magnets from an old hard drive. Over sandpaper there is where to attach it. Magnets add mobility to the searchlight, you can still attach anywhere.
