Hi to all its my post here and i have problem with my projector.
i have epson emp-x3 projector without lamp and i wanna diy it and place LED in it.
first i used 10watt LED 12v operated and it almost gimme 800 lumns but i didn't satisfied with result, then i move to 30 LED 2700 lumns but unfortunately both gimme the same result even 40watt LED i also used the result of three LEDS are the same i don't know what i am missing or what should i do any power full lens or somthing else i placed or what.
there is an other guy told me 60 to 70% of light is waisted and only few lumns come out from projector if collimated light setup is not installed he is famous guy from Romania and put a lot of videos on youtube (aka electrodacus).
He made projector with only 6watt LED in collimated light setup and his result is outstanding.
here is the link of his video must watch:

thanks hope for positive reply

the video link you posted shows the guy having a condenser lens for the led and his image is only 32" and 23 lumens.
In a 3 LCD projector I reckon you loose about 85 to 90 percent of the light you put in so if you have 1000 lumens going in you only get about 10 - 15 percent out and seeing as the 10 W led you used has no condenser lens on it and just spreads those 800 lumens around 180 degree you're left with just a couple lumens leaving the lens.
You need to concentrate the light in such a way so that it's focal point would be right on each LCD screen inside the projector, or you could try using separate RGB leds and get rig of all the lenses and dichroic mirrors in between.
good luck

get some cree or luminus leds, I know they are a bit expensive but they pack quite a few lumens in 5mm or 10mm dies.
Use a high power aspheric condenser to capture most of the emitted light and try and bring this whole assembly closer in the pathway to the LCD's by taking out some of the glass in the path and you will definitely see an improved brightness.
