Hello,
I'm currently designing a strobe light which will be mounted on a small aircraft to increase its visibility. The color of the flashe is red, and should be visible from 1-2 km if possible.
I made a first prototype and today, everything was ready, soldered, 3D printed ...etc. On the ground, the flash seemed quite powerful but for the test in flight, the intensity is quite deceiving.
I am currently using 5 CREE LEDs like this one : XBDRDO-00-0000-000000C01 (datasheet : here)
I am using Carclo 10410 lens (link)
The LEDs are driven by a MOSFET (no PWM, just some flashed controlled by a small board) with 0.8A flowing through the LEDs (they are mounted in series).
I am not a professional and this is the first time I deal with high brightness LEDs, and I guess I made the wrong choice. I saw lots of other items on CREE website but to be honnes, I'm lost.
I saw this kind of LEDs : https://cree-led.com/products/xlamp-leds-discrete/xlamp-xp-g3 but I don't know if they would be more or less visible since the luminous flux is indicated in mW and not in lumens as it is on the datasheed of the XBDRDO LEDs I used.
The only constraint is that I can't use huge LEDs, but if they are a bit bigger than what I use nt, it should be a problem.
I would be more than happy if you can help me in choosing the right components to reach my goal !
Thanks,
L.
