The Glowing Ring

Again and again, looking for interesting and unusual lighting I am today came across a glowing ring. This works when attaching it to the wall, as an access to another world. It could even almost like a fairy tale of Snow White be. Where a magic mirror on the wall of the witch is happening in the country gives up.


But unfortunately we must now do without the magic. The ring is not only suitable for wall, one could attach ropes to the ceiling him. The principle behind the light is actually quite simple. So a ring of iron or plastic is covered with a diameter of about 50cm inside with LED strips. This causes the light represented by the predetermined circuit form a round beam. The ring should a wide from min. have 2cm, otherwise the LED strip is not properly covered. The correct length of LED strip can be easily represented by the formula u = pi * d calculate (pi = 3.14; d = diameter; u = peripheral).

Here’s another quick example
pi = 3.14
d = 50 cm
u = wanted
u = pi * d
U = 3.14 * 50
U = 157 cm
That is, with a diameter of 50cm our circle we need 157cm LED strip.
