Posted by Indrasena, Wednesday, 28 September 2016 on product Colour Changing 5mm Diffused LED - 750mCd

Question:

How can I get the power supply to colour changing LED from 12V car battery ?

Answers:

  • Posted by Michael Lockhart on Wednesday, 28 September 2016

    Hello Indrasena, The colour changing LED has a maximum voltage supply of 5V’s. As such you shouldn’t’ use a supply that has a higher voltage than 5V’s. We also wouldn’t recommend using a car battery to power a homemade device as a car battery can provide a large amount of current and could be dangerous.

Question:

Related to the 12v question; It is possible to put 4 LED's in serial without resistor. Al

    You wouldn’t be able to place a number of the colour changing LED’s in series to allow you to use a high rated power supply. This is due to the forward voltage constantly changing while the LED cycles through the different colours, as each colour requires a different forward voltage. As such if you had a number of these in series you could either not have enough forward voltage for each LED, or when they require a smaller forward voltage you could cause the LED’s to become damaged as the supply voltage then becomes more than what is required by the LED’s.

Question:

Hello, I recently bought 10 of this product and I seem to be having a problem. I don't know much about electronics however I decided to test the LEDs with a 3v watch battery and none of them are cycling colours, they are all just emitting bright white light. Is there something I am missing, doing wrong or have I been sent the wrong product? Batch number is 60113

    I’m very surprised to hear that you are having issues with the colour changing LED’s. If you can email your order details, including your order number (being 03) to sales@kitronik.co.uk we will be able to look a little further into this for you.

Question:

I have a UK 3 pin plug usb charger. This states output is 5.3 v dc. Could I use this to power 10 of these in parallel or is the voltage too high?

Answers:

  • Posted by Aaron Sturman on Tuesday, 12 January 2016

    The voltage is ok, you should check the maximum current your transformer can supply though. If it is over 300mA you should be fine

Posted by Alex Shaw, Wednesday, 6 January 2016 on product Colour Changing 5mm Diffused LED - 750mCd

Question:

You stated in an earlier QandA that you can't run these off 12V, but you can if you use a potential divider, a 750 ohm and 470 ohm resister in series and parallel the LED across the 470 ohm resistor.

Answers:

  • Posted by Michael Lockhart on Wednesday, 6 January 2016

    Although it is possible to run this off a high voltage using resistors it would cause issues with the LED. This is due to the fact that each colour requires a different current, by having a resistor already in the circuit would mean you are limiting the current twice, and would likely stop the sequence running correctly.
