Cockpit Lighting Find

[nobrot]

Not sure if anyone has seen these, but for thos of you backlighting your panels, this little device seems perfect!!

I have used these. The dimmer is great but the potentiometers are cr*p. They usually brake after a few weeks of constant use.

 

I recommend replacing the pot.

In addition....just connecting your LEDs to a potentiometer would have the same effect with little electronics know how (just need the pot).

Exactly Tiger... little electronics experience, I should wear a T-Shirt with that written on it!!

 

Which reminds me... I am assuming I will still need to pop a resistor in series with each LED... correct?

Tiger, I don't agree with that method whatsoever. While sufficient for 1 or few LEDs this solution is not scalable for dosens of LEDs (just how much current do you want to run through that pot? ). We are not 4th graders , might as well do things in proper way . and proper way for dimming a LED is a PWM.

Oh yes...ok...for more than a couple use PWM.

OK i must be missing something, the link is a pwm device isnt it?

Yes it is.

Hi nobrot, I just got some of those PWM to use for my white pannel lighting and blue cockpit lighting in my KA-50 pit. Test tryed with 12 volt led strip lighting and seams to work very good in test. There is a slight humming that can be herd when in either the bright or dimest setting,cant remember which. The led strip is 5 meters long and draws 4.2 amps max.with 600 + leds per strip. Strip can be cut down to a min. of 3 leds. I intend to use 1 and 3/4 rolls for white pannel backlighting. This should keep below the 8 amp rating on the PWM.This will allow me to control pannel lighting briteness with 1 knob. I Hope . Note. when led strip is cut you have to soulder new wires on. each strip is wired in parallel to the PWM.

For Blue lighting I estmate 1 to 2 meters will be needed.

Thanks acemark.. my stuff is still on its way to me so havent had a chance to connect anything yet.. but its good to know that they work!!
