SUBMERSIBLE SAFETY!!!!!!!!!!!!!

PLEASE
Nobody try this set up without a proper fuse/circuit-breaker in your wiring.

Without one there is a MAJOR RISK of fire or electrocution....

Thanks

Bucket and Refrigerator

Of course a bucket might be handy for draining/Filling/Safety-catch-basin....But what is a cooling system without a bucket?


Also a refrigerating coil could be submersed in the tub as well...maybe from an old mini-cube refrigerator like college students have....

thanks

Its time for another good idea/bad idea. Good idea, building a porjector with a high voltage 400 watt metal halide lamp. Bad idea, putting it under water.

Hehe what's funnier than submerging the whole thing in water is the idea of ice cubes in it! You're gonna run get ice every 10 seconds to replace the melted one?😉

HEAT SINK

Also the walls of the tub can be of heat conducting metal....even in a heatsink configuration...to aid in heat dissipation and giant heat sink properties....

There are many variations possible on this theme...

Skeptical OK ----

Its time for another good idea/bad idea. Good idea, building a porjector with a high voltage 400 watt metal halide lamp. Bad idea, putting it under water.

Your criticism would be constructive rather than annoying if it wasn't for the fact that these submersible lighting fixtures are actually commercially produced IN REAL LIFE for application REQUIRING that a light be placed under water....

Please post good comments rather than illogical pooh poohing...

And like i said...design your wiring with a circuit breaker....

THanks...

SOLVES THE PROBLEM

Ok it may not be the prettiest most technologically advanced solution you've ever seen....

But it works and it solves a problem that 3000+ posts in this forum could not solve....

And it's easy to do and VERY effective for this application.

Thanks.

How about Ice Cream?

Hehe what's funnier than submerging the whole thing in water is the idea of ice cubes in it! You're gonna run get ice every 10 seconds to replace the melted one?😉

Tommy

If you don't like water...then how about
auto coolant?

 

[verbose mustafa]

You know... hommie.net used a 1000 watt metal halide setup only being cooled by one fan and he reported no heat problems at all. Im not trying to flame you or anything, it a good idea in thoery, but it just does not seem practical. Good luck on whatever you do. Hell, i would love to see this project finished and working 🙂 !

 

[Property]

practical

Why doesn't it seem practical...

And how big was that guy's fan and how loud? ANd how ugly?

 

[verbose mustafa]

That is a little fan. I forget the size, but those things are not loud at all, and if the noise is still a problem, one could build a fan chamber sutch as alan staples did at diylabs.org and problem solved.

SO then

So why is everybody complaining about heat problems/noise then?

Are you saying i came up with a solution to a problem that did not exist?

 

[verbose mustafa]

No matter how much you cool the lamp, you will still have heat build up on the lcd screen from the beam of light shinning at it. Its just like standing in the sun on a hot day. Same idea. Again, I belive polarization of light is the key to a cool screen. Have i tested this? No. Will I? Yes. I think a most, a fan cooling the lamp, a fan cooling the lcd, and a vent on the top is all that is needed.

Im really sorry if im discouraging you or anything, i just want to show you that there are other options out there (which you probably already know).

Unless you use a blowtorch as a light source, you don't need to do funky stuff like submerging your light in liquid NO2 etc...!🙂

Proper ventilation at the light source and blowing fresh air on the LCD screen itself is good enough. At least it is for me!

Re: SO then

I think you have.. that is to say..the heat of the lamp itself isn't a really big problem. The problem is the heat that arrives at the LCD itself...this isn't caused by the heat of the lamp and socket itself. It's carried in the form of "radiation" by way of the "light beam" if you will. This was explained to me when I posted my info on "water cooled lighting" ...this is why I abandoned the search for one of these lamps.

Don't get me wrong.. a totally silent projector would be VERY NICE! indeed 😉 but I can live with the tiny bit of noise my 5 fans make. I mean it really is not very noisy at all... ANY volume applied to hear the production easily overcomes my fan noise.

Fan inventory: 2X 3"long by 2" diamter "cross flow" fans to cool my LCD (24 volt fans run @ 12 volts)
1X processor fan for AMD500
1X power supply fan for the PSU
1X OHP fan 3M9550 (VERY quiet for the job it does, good engineering is key to quiet fans...and 3M has good engineers)

I've got one for you! Make this work and you will be "Famous" .....at least in my eyes 😉

Build a "light collection/transport system" for a "daytime projector".

Collect sunlight (based on clear sky's obviously) then "pipe" it into a projection unit.

A series of mirrors that track and reflect the awesome power of the sun (how reflective is reflective enough?....old "Star choice" dishes that have been mylared or something?) into a lens of some sort maybe?

Design an "exchangable filter" depending on the power of light provided (hmmm thinking about a "dumbed down" version of an "auto sensing welders helmet")

Comercial "light pipes" are available.

With a well designed system you would only need to use electric lamps during poor skies or at night.

Daytime viewing would be allmost silent...allmost free of electrical cost...."lamp life" would be Phenominal!!!

Night time viewing? Go ahead and build your rig the way you see fit.

This whole assemblage of parts would be a "perma install" of course in some sense's.

Build your "water cooler" anyhow...it's your game.. play it by your rules. You will either prove us wrong and you right (or vice versa) And there will be an "education process" no matter what the outcome is! Knowledge is power.

Just remember if your rules are too far away from certain "laws" such as "death by electrocution" or less serious "laws of physics" something may be doomed to failure. Break the second set of laws all you wish...but as one cannuck to another.....STAY AWAY from the first law OK?

Think GFI ! Make sure it is a properly installed GFI ! Get a pro to put the circuit in for you if there is ANY doubt in your mind (have doubt unless you ARE a pro!).

zardoz....GFI....GFI.......GFI....hmm did I mention GFI?


big post huh? (I've been thinking about the light pipe idea for some time now but it was this post that brought it home for me http://www.diyaudio.com/forums/showthread.php?postid=170157#post170157 ) I currently lack the ambition to take this on...you seem to have lots of that 😉

 

[18wheeler]

Yes, collecting the sun light! I always dreamed one day it might come true. If it can be stored and used later .....

somebody! somebody work on this PLEASE!
