Pharmacy signage display 55
With this video, I present some LED articles made in my workshop on an experimental basis. Arrows and garland. This garland with which I previously decorated my window.
Once I had saved an idea for another decor, I removed this article. This is my first assembly of LED arrows. In addition a multicolored garland.
The LED wiring is done in sets of seven and powered by a traditional 24 VDC power supply. Everything is done in my workshop.
Let’s see this second video, displays on the window the moving garland with variant animations and in the background a sign for a teleboutique.
As I got into LED display, I had created and produced these and other items on a non-profit basis. I had started my profession around 1985, the first article produced was a play of light with color spot lamps.
Its principle is based on three Triacs controlling the lighting of the lamps by audible frequencies. The device must be connected by conductive cables to a sound amplifier. Low frequency
filters have been produced by discrete components. These are non-polarized capacitors and ohmic resistors and a small isolation transformer placed between these filters and the conductive wire of the signal to be taken from the amplifier. of his.
Afterwards, I opted for an improved creation Well, it’s done independently. A play of light with power supply and micro chip to capture sound waves and activate low pass filters controlling the lighting of the spotlights.
After all, everything is abandoned. I would come back more pie for another innovation by way of research. It was successful, but I hesitated to continue this walk. Let’s see the video from below.
This is something special. This a so-called analog and digital realization. So, I conclude this article a little varied but it revolves around the lighting in general.
Previously, before the era of RGB LEDs and other colors, named accustomed to these fragile neon signs and consuming much more energy. The flashers made are triacs. On the other hand, for LEDs consume low electric current and low power.
