Ok its been a while since ive been on these boards so i have alot of catching up to do. Well i just got a sharp xg10x or some model like that. Seems to be a great projector and now my side project is to retrofit the light source. Right now im using a seoul p7 and so far it seems pretty promising, i did the lamp bypass mod and just put that led in there to see what i could get... well the result was quite sub par but i just ordered a lens to bring the 130 degree viewing angle down to 3 degrees.. i hope this helps collect the light and get it where it needs to be. Any suggestions? Also i stumbled across the idea of using high power red green and blue lasers but im not sure how id rig it up and if it were high enough power to give a good result would it put out to much concentrated heat and ruin the projector? I guess right now i just need someone with better knowledge of how the dlp optics work. From what i can tell it goes straight from the light source to the color wheel which makes me believe the source needs to be prettty focused. I will let you know when the lens comes and what the results are. Untill then all input will help. Also i was wondering if maybe i could use some mid power lasers with the p7 or maybe ad another p7 to the lens but we will see what it looks like when it comes.
My understanding has always been that the heat sensitive part is the bulb. If your bypassing that with a laser I wouldn't worry about it too much, then again I've only used the equipment as the vendor intended too. Hey, the wost thing that could happen would be that you need to buy a new projector right?!

lampretro ..I would really like to know the details of how you modified the other projector..the Sharp xg10x projector? Could you email me with details? I am trying to retorfit one myself but can't quite figure out how to bypassing the lamp so I can use my lamp source. Wish I could help you with your laser issue. If I see anything on retorfitting for a laser I will post the info.
hey it took me a minute to do, you have to look around for threads, people have covered it a bit but unfortunately it is different for every projector. You will have to find the wires for the 5v lead and attach it to any ground as far as i know. For me i just grounded a wire and touched it to different ones until i got results. Which projector are you using? At first i got shitty/no results using an led... but i moved the color wheel and put it right infront of the dlp chip. This way more light went in the first optics and actually got some damn amazing results for a single led! Then i dropped my projector which was on my keyboard part of my desk, also pulling down my dvd player and killed them both... arg. But i got a new fully working awesome projector on ebay for only 70! best deal ever, but once this bulb dies i will try to retrofit with an led again, im lookin forward to it. Also i know a laser would be a great option but the green lasers are hundreds of dollars so its pretty far away.
no lasers
Correct me if I'm wrong - but a laser light source sounds like a non-workable idea (and unsafe).
Um... if you know anything about lasers... it says something like "dont shine it in your eyes" on it everywhere. This is also a well-known fact.
Also, a laser sounds like a pretty bad light source. Put one of those in a normal projector and you'll likely see an itty dot instead of a square image. Lasers are DIRECTED light (all the light goes in the same direction), not radiated light like bulbs. Also, directed light will heat up the components quicker.
I would not use a "high powered" laser unless you want to melt something or burn out your eyeballs.
I HAVE heard of laser powered projectors, but I'm guessing the idea is that it is a scanning laser like the scanning electron beam in a CRT.

lampretro.. many thanx for the reply. I have a Lightware Traveler AKA - Plus U2 1100. Nice little DLP projector. Looking at another projector and not sure which one to get. The worste part of this is I have the best way to retrofit any of these DLP projectors with a much cheaper lighting system, but just as bright or brighter and no need for fans and cooling for the projector. It's simply a matter of bypassing all of the electrical they put into them. Will keep an eye on this forum.
Also meant to mention ; as you may be already aware of. The end of 2008 a few companies are to be releasing the new LED 3 DLP chip projectors. Each DLP will have it's own colored LED and will NOT have any use for any fans! Best of all the new LEDs are called Phlat Light LEDs. They produce an enormous amount of light and they expect these projectors to have a lamp life span of around 100,000 + hours. This means all of these mercury arc / intense heat and expensive metal lamp projectors are history and if we can all get our hands on a few of the great models and retrofit them without those expensive lamps until the new projectors come down to a reasonable price.😉
By the way, if you happen to use LEDs with your projector I believe you may be able to get a descent picture. Goodluck with that and keep us posted! I personally will be incorporating fiber optics to do away with heat in the projector... IF I can bypass the lamp <G>
