Hello! I have been browsing the internet for a while trying to figure this out on my own but I think it's time I ask for some help. I would like to apologize upfront if I missed a previous thread on this exact topic, I saw a few that are related but I still have some questions.
I am trying to maximize the range of an IR illuminator using the following LEDs-
10mm Triple chips 200mW IR LED
http://www.lightobject.com/10x-10mm-3-Chips-200mW-Infrared-IR-850nm-LED-30-degree-P91.aspx
I have looked into linear and switching regulators but this concept is new to me and I could really use some input. My only requirements are the 200mW LEDs and portability. I would prefer to stick to a 9V battery due to its compact size but I am open to alternatives. I am not expecting step by step instructions, but rather for someone to perhaps give a quick summary of the different techniques I could utilize to increase the LED output.
Also, if anyone has a better idea in terms of the LED itself I would love your input. I have already tried reflectors and using no more than 5 LEDs per 9V.
Thank You!
