How does this LED work?

Hi, an embarrasing question but can anybody tell me how does this LED work?. I mean construction kindof way. This gives three colors and has two terminals. And just giving it a supply makes it glow in all three colors one at a time. It looks like a normal LED. Googled it but found multiterminal RGB LEDs. Video attached.

Thanks.

If your LED is anything like these:

Then just connect 5 Volts DC and it works.

Of course, your LED may be different, since you provide no information. Maybe 5 Volts will kill it.

EDIT: .... or if you mean, how do the internals work... I believe that it has a chip built in to the same package as the LED.

It's a Flashing RGB LED. Basically it has 3 LED diodes and a microcontroller built into a standard 5mm LED package.

Search google for Flashing RGB LED and you'll find these.

I have some of these kinds of LEDs too and mine work perfectly on 3v, it has a built in chip that powers the LEDs in some patterns.
