LedLamp 3D Model

I created this table lamp with a height of 40cm and specific design and 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 Example: 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.
