Glowing LED Tubes

I love LEDs. They are economical, durable, and most importantly very beautiful. And I'm always looking for new ways to use them in a new way. Here, for example, is a great way to use two super bright blue LEDs and a tube 8-10 centimeters long. From these components we will make a tube similar to a neon one. A great way to do computer modding.

The tube must be filled with fluorescent liquid, due to this, the effect of a neon lamp can be created. In addition to the components listed above, we will need a fluorescent marker (can be bought at most office supply stores)

Preparation of the dye. Take and disassemble the marker, pull out a rod saturated with paint from it. Let some alcohol or some kind of alcohol-containing solution, such as cologne, pass through it. The resulting concentrate is diluted with water. We got a liquid that reflects light well.

Next, cut off the necessary piece of a transparent tube and firmly insert the LED into one of the ends. At the other end of the tube we pour our liquid. For this operation, I used a plastic bottle with a pointed neck. Pour liquid without bubbles and insert another LED.

For complete tightness, you can glue the ends of the tube with LEDs with glue.

A long tube should not be abused, because if you take too long, its middle will be poorly lit.

Everything, our luminous tube is ready. We check. For this purpose I used batteries - 3 volt tablets.

I experimented a lot with the colors of the LEDs, I even took ultraviolet ones and found out: the most effective are the blue LEDs. They produce the longest tubes that glow more evenly over the entire length than tubes with other LEDs.

Well, and where to use these magnificent glowing tubes, think for yourself. Good luck
