N00B needs help

[ace3000_1]

Oh, I've thought about a lot of these sorts of things. If I just wanted a projector, then I would have bought an OHP panel on ebay and an OHP at a yard sale. But I'm more interested in learning about all the possibilities.

Im the same mate, i try to get the best out of somthing lol or try to improve on an aspect in a design ect, isnt life boring just buying stuff and not learning?

An elliptical reflector that is bigger than the LCD would be very cool! It could converge the light through the LCD panel, and right into the projection lens. No condensor, no fresnels!

Possibly, not saying that it wont work cos it will just how well is the question as the light wont be going through the lcd paralelle.

I once made a 4 foot diameter parabolic reflector when I was a kid out of masonite, heavy paper, and aluminum foil. I might just try that again as a prototype, once I have a lamp and get my panel running again.

I do alot of sheet metal work and ive made a few , but its just one of those things where as its just as easy and cheap to buy one, acuracy is always questionable aswell, ive got few light engines that ive made in the past that basically recycles light, ive made others aswell that are basically just a big reflector that houses the actual normal light engine to capture the lost light. At the end of the day with the wide range of optics and projectors, we have unlimited possibilities, having this technology available to comsumers now days also helps.

Actually you can, im suprised no body has thought in how to do this yet, im holding it back for now (atleast until i try it first ), same with the reflector link as its been proven in the past my links and designs are what some others like to profit on.



Osram, here is their spec sheet.

Anyone knows if this bulb is available in the US? Or of any other places that can be ordered from ..online ?

That can't excuse measurements' tolerance either. The conjugates are unique. If you have one, you have exactly another one to form a pair for a given thin lens (their name suggests this too).
Humorous debate, though
