I created this table lamp with a height of 40cm ,consisting of 8-13 pieces, so it can be printed on 3D printers.
Lamp can be fitted: 3-5 base legs ,1-3 rhum / hat / arrest
The body is drifting on the cable. One lamp hat fits 4x5mmLed.
When installing rooted LED diodes, an example for calculating the resistor
Battery voltage is 12 V and we have the following data from the catalog:
LED voltage = 2 V a
the maximum possible current flowing through the diode is 20 mA.
First Specify the resistors size.
UR = Uz-Ud
Secondly, by ohm the law, we calculate the resistance of the resistor.
For U, put the already calculated voltage on the resistor (10 V) and after we mount a current that can flow through the diode (20 mA = 0.02 A).Watch the current in mA! If we get 20, it's nonsense.
