The design consists of two parallel mirrors, one of which is translucent, as in a laser cavity. If a light source is placed between these mirrors, a very beautiful effect is created that goes into the distance with a backlit tunnel. That was done - between the glass was installed 36 super-bright LEDs and a backlit fan for beauty and cooling of the body space.
Then connect them in parallel with a wall-mounted installation, with each LED having to put its own ballast resistor with a resistance of 820 Ohms as shown in the figure.Next, you need to make threaded bushings with screws. A screw with an M6 thread, or any other that doesn’t matter ... but the sleeve is 10-12 millimeters long.
In fact, the depth of the tunnel directly depends on the distance between the mirrors. Everything is limited only by free space in the case. Assembly is carried out in accordance with the figure and is not difficult. I recommend also covering the side of the cooler so that it does not reflect in the mirror and does not spoil the picture. The cooler can be covered with a decorative cover and a protective net, as in Figure 14. The finished product should look like the last figure. I hope you enjoy it.
The threaded sleeve was machined on a lathe, which is not necessary. It’s enough to pick up the bolts with a beautiful hat.
Assembly drawing. Cardboard washers are recommended under the hats to reduce the risk of glass breaking.
The fan grill is typical, from the power supply. I made the frame myself out of stainless steel.
