====== CftL-LED-Bar ======


===== Description =====
The [[ADI>CftL-LED-Bar]] is a boards that contains LED's with 3 different spectral outputs (627nm, 530nm and 470nm). Each of the three channels contains a string of four LED's in series able to handle currents of up to 1A.

=====Connectors=====
==== Screw Terminals ====

Screw terminals P1, P5 and P9 are connectors for the anode and cathode for each of the red, green and blue channels of the [[ADI>CftL-LED-BAR]]. Pin 1 is the anode and is to be connected to the positive terminal of the source while pin 2 is the cathode and is to be connected to the negative terminal of the source.

====3 Pin Headers====

The 3 pin header is used to add LED's to series string of each channel. Placing a shunt on +XLEDN, where X is for the channel to be controlled and N refers to the LED number, adds the next LED on the string and placing the shunt on GND position terminates the string, connecting the last LED to the negative terminal.

===== LED Ratings =====

==== Red Channel ====

Each LED on this string has a typical forward voltage of 2.9V and tested with 500mA of current. Adding LED's to the string of LED's in series will result in a higher forward voltage. Please see below table for reference:

|No. of LED's|Minimum Forward Voltage Required|
|1           |2.9V                            |
|2           |5.8V                            |
|3           |8.7V                            |
|4           |11.6V                           |

==== Green Channel ====

Each LED on this string has a typical forward voltage of 3.21V and tested with 500mA of current. Adding LED's to the string of LED's in series will result in a higher forward voltage. Please see below table for reference:

|No. of LED's|Minimum Forward Voltage Required|
|1           |3.21V                           |
|2           |6.42V                           |
|3           |9.63V                           |
|4           |12.84V                          |

==== Blue Channel ====

Each LED on this string has a typical forward voltage of 2.95V and tested with 500mA of current. Adding LED's to the string of LED's in series will result in a higher forward voltage. Please see below table for reference:

|No. of LED's|Minimum Forward Voltage Required|
|1           |2.95V                           |
|2           |5.90V                           |
|3           |8.85V                           |
|4           |11.80V                          |
