Led Engin RGBAW Problem...

[C1p86]

I've a problem with a LED Engin LZ4 10W Multi Color:

Connected to a Petit Crouton Sound Module V2.0 it make not too much light (a little bit less than a Seul P4 connected to a Petit Crouton Sound Module V1.5).

I use Li-Ion 3,7V, 900mA.

I tried connecting directly battery to the led and it make a little bit more light, but not enought.

Just for explaining myself: if i put on the blade, it is not lighted till the end.

Any ideas?

Thanks!!!

do you have the leads wired correctly to led?

I could be wrong, but I don't think one 14500 cell is enough to power a 10W LED to full brightness. You would need at least a 2 cell, 7.4V pack, methinks. But, I'll let the other more experienced smiths here chime in.

Tim has data sheet lin at the shop for led.

If you're only running one cell, the PC absolutely can't run the LED and itself off of one cell. You need a 7.4V series pack for the PC to be able to drive the LEDengin (or run at all). Also, what dice are you using on the LEDengin? Just one die for one color? You do realize that each single die on a four die LED is only about as bright as a P4 or so right? You have to connect more of the dice together (different configs depending on color) to get the most out of the LED.

Sorry, my fault. Of course I'm currently using TWO cells
And the led is also wired correctly.

Could be a problem with the amperage of cells?

The problem is that if I'm not into a completely-dark room, the second half of the blade is not lighted at all...

Listen to Fender you should.

Does the blade have any diffuser film? Several layers of polypropylene will help.

However, also, ditto on listening to Fender. You're not going to get full power out of that LED module with only a few die wired. That's to be expected and unavoidable if you want to do color mixing.

Other factors to consider are: how much current did you configure the PC 2.0 to output to the LEDs? And are the LED dies wired in series or parallel? Parallel will split the current, so if you have two dies wired up, each one is only getting half of the current output.

So if you configured the PC to output 1 amp and two dies are wired, then each die is getting 0.5 amps. (500ma)

Edit: If you don't need to do color mixing then you should consider a different LED. If you only want to do red, green or blue for instance. Or white.

No, I need color mixing!
Thanks, I missed the option for customizing the output Amps!

If I use two led (blue and green), have I to set to 1400amps? (700x2) ??

That's correct, except that you mean 1400 milliamps which is 1.4 amps. And yes, if you're wired in parallel then you're splitting the current so that each die is getting 0.7 amps. The PC 2.0 can output 2 amps which would give each die 1 amp, which they are capable of handling.
