BridgeLux LED Array - Overview
Created By: Chip Swieringa - email@example.com
I recently became a customer of Newark Electronics (aka Farnell) and
noticed they exclusively offered an interesting family of LED arrays by
BridgeLux. Consequently, I noticed a severe lack of consumer review information.
I decided to fix that.
BridgeLux LED Arrays - Cool White
6 die - 440 Lumen @ 600ma 9.8Vf
12 die - 880 Lumen @ 900ma 13.0Vf
16 die - 1320 Lumen @ 1300ma 13.2Vf
25 die - 2200 Lumen @ 1750ma 16.6Vf -- WOW!!
|Color Temps|| These four LEDs are Cool
White with a 5600K color temp.
They are also available in:
Neutral White (4100K)
Warm White (3000K)
Both types cause considerable loss in output efficacy.
The 2200 Lumen array is only available in Cool White.
(NOTE - These pictures were taken after extensive testing, soldering, clamping, etc... and will demonstrate wear characteristics.)
|Model #BXRA-C0400 - 440 Lumens
|Model #BXRA-C0800 - 880 Lumens
|Model #BXRA-C1200 - 1320 Lumens
|Model #BXRA-C2000 - 2200 Lumens
LIGHT 'EM UP!
This set of pictures are of the 1320 Lumen array. The camera
has difficulty capturing the true apparent brightness
of these LEDs, especially since there are no optics to generate beam shots. Because of this I took very few
photos to demonstrate brightness.
|Relative Brightness - This is roughly the apparent brightness.
In this photo the array is being UNDERDRIVEN at 1000ma output rated at 1052 Lumens!
|16 Dies w/ Fuzzies
You'll have fuzzies all over it without meticulous and persistent cleaning.
This photo is greatly underexposed to show the very thin power leads going from die to die.
|Blinded By The Light
Opps! This picture was accidental. I was making adjustments when the camera timer ran out.
It was too bright to see what I was doing!
I was using a LuxLuthor 15.6v pack for that test.
4000 LUMEN MONSTER
I decided to push the 2200 Lumen array as far is it could go! The following pictures are the result of that experiment.
|A 25 Die LED Is Pretty Crazy
Here is the test bed. To safely push this LED to the extreme I chose
to use Peltier cooling to keep temps
LED Case Temperature Before Test
The Peltier cooler brings the LED temperature below freezing before the
Crank It Up!
In Constant Current mode I set the LED current to a steady 4 Amps.
LED Case Temperature During Test
Even with the Peltier at maximum cooling the case temp still reaches
over 200 deg F.
At 4000mA the LED output is literally off the chart!
