For this version of the projector lamp I knew I had to find a way to at least double the amount of light on the projection screen. As high-power LED’s are very expensive parts around here (I live in Sibiu, Romania) I wanted to try making my own LED array. I chose the NS6W183T LEDs from Nichia. For those of you who don’t know, Nichia is a Japanese company that produces high quality LEDs and were the first to invent the high power blue and white LEDs back in the 90’s. These LEDs were available around here and the light output was tempting.
This instructable is not yet finished. Also the timeframe on this project is unspecified. I'm publishing its progress because I need other user's opinion on some matters in order to finish it. If you think you have something truly valuable to add to this project, be my guest and share you opinion in comments. I'll try to answer them all.
