fluorescent light change color with frequency

[zawminoo]

Hi everybody,

I would like to change color of fluorescent light.
How can I change these color.
I think that it can change color by changing frequency.
Right?

Please help me if you have this project.

Thank!
Zaw

isn't easy that you want!!!

i think fluorescent lights rely on the monochromaticity of the gas filled in it... i dont think you can change colour....

Hi Everybody,

I have seen a bulb which is changing colors.
For example...
First,it is red and then 20 second later it change blue and so on...
(it can change 7 color)
I would like to know how it is.

Thank,
Zaw

Maybe you saw an LED Tube Light. It contains rows of color LEDs in a tube. Here are some manufacturers:

ya i too think the same... fluorescent light depends on the gas filled and its emission spectrum... there is no way of changing the gas in it and even if many gases are used the other lower energy colours would also be present....

so it must have been LED lights.... but i'm not sure of the 7 colour thing you are mentioning....

Totally agree with the light emission related to the gas choice.
We're very probably dealing with multi-color diodes.

BTW you can find many of those on http://www.tom-ic.com/index.php?cPath=27
If you'd like multi-color LEDs, it's no problem. Just use our BOM service **broken link removed**.

Actually, it might be possible to change the fluorescent light color. It looks like they coasted two different color phospers that has reacts to different UV wavelength and got the tube to emit different UV wavelength to activate the color you want....

But, yeah, it sounds like what zawminoo is discribing is color changing LED based light.

this is pretty cool.... rowokii can you please post the links of the two colour fluorescent light you are talking about....
just curious to know how they switch the emission spectrum of the light...
