BLUE led TO wHITE?

Hi ALL; I have a bunch of blue LEDs which I would prefer to turn white . Possible?
Thanks, Alberto.

No.

You want to take a manufactured blue LED and remanufacture it into a white LED?

Google phosphorus coating white LED.

@larryd, you're explaining too well. The OP won't be able to understand!

Fish, banana, Wednesday. I hope that makes things suitably un-clear for you.
(Oops. I shouldn't have mentioned the bananas)

Sheesh, some people.

Sell blue LEDs, use money to buy white LEDs?

or buy red and green leds and turn them all on...

I think with enough current, a white light will appear when the leads start to arc. Assuming nothing else in the system starts making white light or smoke or an orangish plasma like substance.

Hi Alberto, the first answer was the best one - the answer is no, you cannot turn a blue LED white (Larryd's remanufacturing scheme not-with-standing - that would work, but ... it would be somewhat complicated.) You can get a 3 color LED, which has red, green and blue LEDs in a single package. Then you can make it blue by energizing only the blue portion, or white by turning them all on. Google "tricolor led".

Now I want a brown LED.

Yes, you can't even make brown with an RGB LED.

I solve all these problems by buying assortment kits where possible. Only specialist items are bought separately. This applies to resistors, variable resistors, capacitors, leds, general purpose transistors, nuts, bolts duPont connectors, etc. etc.
So, for example, instead of buying separate leds, I'd get this.
My local supplier cannot even send me one led for the price that I pay for a 300 piece assortment kit. The disadvantage is that I have to wait 2 or 3 weeks if I order from China.

Understood; just thought that someone knew about a paper filter, paint, whatever. THANKs.

It’s physics, you can use a blue filter on a white LED because white light contains all wavelengths of light and a filter can remove specific wavelengths. Where as a blue LED only contains blue light and to make white light you also need red and green light.
