Yes, there is alot of information missing. If you want to connect 24V to a LED, there is no need to convert it to 12V. Just a series resistor of 500 0hms or so wll do. If you give me the specs for the LED, I can show you how to calcualte the exact resistor value.
If you want to connect 24V to a LED, there is no need to convert it to 12V. Just a series resistor of 500 0hms or so wll do. If you give me the specs for the LED, I can show you how to calcualte the exact resistor value. I would say 600 ohm (24V - 12V = 12V/.02 = 600) but 12V is way too much for a single LED. Wattage is probably 1/8. Thanks!
If you already have one, give it 12V and see how much current it takes. Then the resistor is 12V divided by that current (in ohms). What size wattage is again that current times 12V (in watts), and you can cheat that number since it will not always be on. By just giving it 12V from a fixed regulator you can bypass the measurement.
Always choose a power rating at least 2× higher than calculated power to ensure safety. Always calculate worst-case current and voltage conditions. Use resistor series like E12, E24 for available values. Double-check with a resistor calculator or simulator tool. Choose resistors with flameproof coating for power circuits.
