Hi All;



1.Can anyone point me to a source of "dimable"12v LEDs for cockpit/panel lighting

2. Also a source for 12v flashing LEDs for use a warning lights.

 



Many thanks.

Bill Allen

  There are no 'generic' 12v LEDS. The light emitting diode

  is a current driven device with a voltage drop on the

  order of 2 volts for red ones and up to 4 volts for

  white and other colors.



  You operate an LED by causing the desired current flow

  through it. This is often accomplished with the selection

  of a series resistor. Hence, many "12V" red LED fixtures

  operating at say, 20mA, will mount the red diode in a

  package and add a resistor that turns the 10V difference

  between diode and supply into a 20mA current flow.



  R = 10/.02 or 500 ohms.



  ALL LEDS are dimable . . you simply control the current

  from max down to zero (the very tiniest of currents

  will produce a visible glow on the device).



  There are a family of LEDs with built in flashing

  features, but I've never found one that produced enough

  light output to be a useful warning light on an airplane

  panel. If you want bright, dimable and flashing, you'll

  probably want to craft a suitable suite of electronics

  to go with it.



  How was it that you wanted to use LEDs? What colors?

  Do any of the applications call for multiple diodes

  to increase light output or coverage?

12v LED strip from the local store (such as this),     hooked up to one of these dimmers     should work for the cockpit?

     

     Something like this     for a flashing LED?

Bill,



Search Amazon for 12v LED Light Strips.  They also have dimmers, connectors, etc. for the strips.

I recently ordered a reel of the LED strip, power/dimmer & connectors.  Won’t arrive till after Thanksgiving as they are probably shipped from somewhere in China.

You can also find your individual warning lights there as well.
