BNC Adapter Lamp

BNC Lamp

I had a bunch of BNC right angle, straight, and T connectors, so I decided to make another lamp. Click the picture for more.

I didn’t want to purchase anything for the lamp except the polycarbonate diffuser rods, which is McMaster #8571K44. The 5/16″ diameter rods were cut to length and a 3/16″ hole was drilled through the center to fit over the LED.

The individual blue LEDs have a 68 Ω resistor soldered in series, and a 5V power supply to the entire thing with the center as the positive rail. Wiring LEDs in parallel can be a bad idea, so the resistor is out of necessity. The LEDs were sanded down to size with a dremel. Click the pictures to make them big.

Greetings,

I am always interested in learning more about what materials are available for building things.

What is a diffuser rod?

Was polycarbonate chosen over other materials such as acrylic for any particular reason, or is any similar transparent material just as good?

Thanks

Cosmic Voyager – The diffuser rod is the translucent rod that makes the LED light source a little more fuzzy.

Polycarbonate was what was available from McMaster. It was translucent, which is why I used it.

Very well done, and thought out. You’ve given me a few ideas to do the same with a bunch of old brass piping I’ve got lying around. Thanks for the inspriation!

Hey, Russ– long time no speak!
‘Just saw you on Make– killer lamp! ;)

Fantastic! Am I correct in assuming that the LED modules simply connect with the existing contacts in the BNC connectors, and that power is distributed through those BNCs?
