What power supply and resistors are needed for 3 diodes?

Question

Electronics

I am asking my question again in a more refined form. In short, I'm making interior lighting for the figurine. Made wiring for serial submission. There are 3 diodes I want to use: www.betlux.ru/BL-L502%205mm_LED_lamp.html, www.betlux.ru/BL-L413%204mm_LED_lamp.html and www.betlux.com/product/LED_lamp/Round%20Tower% 20LE...The problem is that I do not know what power source to make everything work. From my previous question, I found out that it is imperative to use resistors, they even suggested how to calculate the required resistor using an online calculator, but unfortunately I am a complete log in the matter of electricians =) Therefore, I ask for help on how I can figure out which particular power source and which resistor or resistors I need use. It would also be great if you enlighten me about the connection. In the previous question, they gave such a scheme: Is it necessary to do as on it? I've already bricked up the series circuit.... Can I use 1 resistor instead of 3?

Answer 1

5 suitably sized batteries connected in series with an operating voltage of 1.5 V and one 68 ohm resistor. Or 6 batteries and 150 ohms.
This is a very conditional calculation, made from the average current and voltage values ​​for these LEDs.
