If you suddenly have a monitor lying around with a faulty LCD, you can try to make an unusual lamp out of it. I have long been lying around in the garage and calloused my eyes 17 inch ASER. Throw it away - the hand did not rise, repair it - the hands did not reach. In the end, I decided to adapt it for at least something.
First you need to disassemble it, including the matrix in which the backlight was faulty. When you disassemble the matrix, you will fall into the hands of various interesting films and glasses.
Do not throw them away, they have very interesting properties and they can come in handy in the future.
When I got to the lamps, I deleted them and put in their place the LED strip, which I also have been in since time immemorial. The width of the tape and the width of the lamp tray fit perfectly.
After that, I put the modernized lamps in their regular place, at the ends of the glass plate - the fiber. He applied power to the tapes, looked, it seems pretty turns out.
At the same time, faulty LEDs appeared in the tape, simultaneously replaced them.
LED strips require 12 volts. This is exactly what is available in the power supply unit of the monitor, we will use it. To do this, remove the power from the inverters, and apply 12 volts to the standard connectors for connecting the backlight lamps with wire jumpers.
Now we need to collect all this economy, which would be like a finished construction. When disassembling, I put aside two films. One white matte, I put it first so that the contours of the metal base would not appear. On top of the mat I put a shiny reflective film. And already on top I laid a glass plate with LED strips built into the ends.
All this is fixed with standard frames and slats and fixed with bolts. At the end of all the manipulations we have a lamp in the monitor body. It obviously cannot be used as a searchlight, but it can be suitable for creating some kind of background lighting.
Maybe someone has more fantasies than mine and come up with something more interesting.
