Electroluminescent backlight: cold neon
It is inspired by the last post about lighting the room with LED tape, as well as topics about the lighting of system units, tables and other things.
It is clear that this is not entirely habramema, but when I saw the number of comments to such publications, I was surprised and decided that one interesting, in my opinion, technology was unfairly bypassed. It is called "cold neon". Tested in our online store phosphor .
Most use for dim backlight in cars. It is interesting to see the illuminated bikes (+ a small power supply from two batteries - enough for a few hours of illumination) or sneakers. Photos are not mine. The last photo is a power supply unit on two finger-type batteries with a connector for connecting and a coil of cold neon (5 meters).
I used this thing instead of a garland on a laptop in the office. Unfortunately, the photo is not saved. I used USB wiring for connecting and 5-meter piece of wire.

The principle of operation is very simple: a current-carrying wire coated with a phosphor, over which thin contact wires are wound. With the passage of current through the wiring induced a weak magnetic field, which leads to the effect of electroluminescence.
The phosphor itself usually has a yellow-green glow, so for a variety of colors all this is covered with a “transparent-colored” PVC tube on top.
What is interesting:
It is very easy to connect even to USB or batteries. The only thing that the phosphor, which covered the wire, with careless handling can crack, so you can not bend the wire. But even in this case, it will continue to work (a dark spot will simply appear in the damaged area).
It’s easy to solder cold neon, but I didn’t manage to clean it so as not to tear off thin contact wires the first time.
PS I have several sections of cold neon left in the storeroom with various connection options - USB, batteries and a module for auto.
UPD: I have a few more materials that are associated with phosphors and their use. If the community is interested in this topic, I will prepare articles for the specifics of Habr. Waiting for comments.

What is interesting:
- extremely low power consumption (10-15 W / m depending on thickness). Thickness is usually from 0.8 to 5 mm
- can be used in rooms with high humidity
- can be found any length - sold in coils
- practically does not heat up with prolonged luminescence
- there are not only wires, but also tapes and even panels
