LED+FLYEYES+COLLIMATOR=LED projector

[chinajin9999]

hi,
The image is as following
There is a screen on the wall, and you can find some waves there. And becasue I just use a 600M camera, it is not so good as it is. More pic I will show you later.
I must go to find some other camera

[chinajin9999]

More pics by myself.
1. The uniformity is OK,
2. The environment brightenss is about 6 lux, I turned on a desk lamp behind me.
3. No screen on the wall again,just white wall.
4. an copy DVD popular here in China.
5. I use auto mode( I do not know how to operate an camera), while press down the flash light (not let it flash when taking photos).

Looks like it will not fit in a commersial projector, to big. But it is a nice desing for small lcd panels.

[chinajin9999]

you are right,
it is not for a DLP or 3LCD projector case.

but for home use, or DIY , it is perfect.

For this engine, we can use 3.5" LCD, 5" LCD, 6.4" LCD

very nice pics and interesting design. I wonder if this would ever be designed for larger panels = more led's = more light but also more expensive i guess.

How about if thiss can be design for small 3lcd comerciall projectors. One can buy cheep 720p 3lcd whit broken lamp and retrofited whit led module if it is done write. 3 lcd panels is vastly superior to 1 panel.

Now it is 19 Led LAMPS.
The total output of the lmap is about 4200 lumens

with the same engine, we can make 31 LED lamps, and the total output of lamps is about 7000.00 lumens.

with a larger LCD panel, the brightness, you can calculate youself. The result is that: The image will be as bright as entry-level DLP projector( with so-called 2000 lumens peak brightness, but the dynamic image is only 400 lumens. 2000*70%*33.3%=466 lumens).

This brightness, for home, basic office use, is OK.


For those 3LCD projector, this engine can not be put into use. There is an optical theory: The lights can not be condensed as you want. That means, the intensity of the lights is decided by lamp attributes. Only high brightness dot-light-source can be used for small LCD panel.

If one day, one LED can produce 5000 lumens, 3 LCD projector can use LED as light source.

Hi, the guy from South Africa, I am dreaming of going there to watch world Cup!!!!!!!!!

[giorgos18]

We're very excited for the World Cup. Just like China had hosted the Olympics Beijing 2008, it is the same type of excitement gathering

As for the projector, you make some interesting points. It would be nice to fit a 12.1" screen with nice LEDs and nice large fly - eye lens

I can't tell from the pictures, but is there any "hotspotting" caused from the LEDs or is the lighting very even?

How many LED's could cover a 12.1" screen, dimensions 262mm x 158mm viewing area?

Also, could you post some of your pics at diyprojectorkits.com forums? I think the community would definitely be interested to see your results

Thanks!

[chinajin9999]

Oh, Great!
Hope your people can host a wonderful Cup for us all!

1. The uniformity is more than 85%. You can judge from my data listed above.
2. No highlighted spot anywhere on the screen. This is the function and advantages of the flyeyes. There are 2 pcs of flyeyes working together, (back on back).

3. Tks for your suggestions, I will go there.

Thanks for your anser.But again there are alredy LED projectors whit LED modules. LG 160 lm, SAM 150lm, benq 150lm , all RGB LED modules.That is no bad.If used whit higth gain screen, almost perfect.There are very good reviews at avs forum. Vivitec ,Delta ,Benq will be seling this year 1080p whit 800-1000lm DLP and LCOS projectors.That makes me think, that, there has to be a way of retrofiting a commercial projector,even if the light engene is outside but atached to projector.What do you think?
