who can build this for me?

[hamheart]

sorry about the bad drawing and the fact that it is upside down. this design does not need to be in a mag body or have that type of battery setup. if somebody can make this pm me. also if anybody has suggestions or ideas post em'. thank you

That might be possible if those are 5mm LEDs, but you're looking at a total output of maybe 15 lumens, about on the order of a stock MiniMag. It would have a very "full" beam though, basically would just throw one big smooth hotspot.

You could get the same effect with less complication and a lot more lumens; if you have the money for this kind of build, then you could probably afford a McGizmo SunDrop (http://www.candlepowerforums.com/vb/showthread.php?p=2694536#post2694536), which achieves the same full beam using a single emitter behind a fisheye lens, no reflector - a much smaller and more efficient design. It also uses a special high color rendering LED, which reproduces colors much better than standard LEDs.

This thread may provide some insight.

I was more thinking of using p4's or xre's for the LEDs, but thank you

That would be a no-go, you need a whole lot of metal mass to sink heat from a high-output LED (note the size of the aluminum slab in LumenHound's link), anything more powerful than a 5mm on a thin bar as per the illustration, and you're looking at a few seconds runtime at most.

here is the edit, this better reflects what i had in mind.

His design is entirely doable with high power LEDs. They could be attached to a heat pipe which would carry the heat down to the metal body. That said I see no benefit to this design. It will just be a pure flood beam which could be accomplished by simply facing all the LEDs forward. It would in fact be much more efficient to just face them forward. Not to mention you would not need such a huge head. Sorry Hamheart. Unless there is something else to the design that I have not seen I would not bother pursuing this.

I know I've seen a thread on this... where someone constructed a plate of metal and put two LED's facing in each direction. Then they took a triangular shaped piece of metal and put three LED's facing 120 degrees from each other.

I think it was done in a Mag host.

I have no idea on how to search for it.

It was McGizmo who made one,

You could use a square heat pipe for the led's to attach to, that might transfer heat better than a solid metal piece.

All you gotta do is test.

You have an interesting idea. Don't let people put you off. You should pursue it and see what comes of it. What you are trying to do has been explored by TerraLUX also: http://flashlightreviews.com/reviews/terralux_tle-6n.htm

If I were you I would build a test rig. You should be able to cobble together some things to test out your idea and if it seems to work well then you should find someone to commission to make it. If not, well then go back to the drawing board and adjust the design.

Remember that many of the custom makers here use smaller lathes and the size of the reflector alone will preclude them from doing such a job. When you have a solid design worked out you will want to find a good machine shop hopefully locally to build the body and people who make reflectors (custom light makers should be able to help you find someone).

It is an interesting idea. But not a good one as laid out. Not trying to be rude just honest. There is no reason to encourage the wasting of his time and money on this design. Did you even look at the page you linked to? Those beam shots are some of the worst I have ever seen from a flashlight. Granted his design would not have that same beam since his design uses a straight reflector instead of a parabolic one. Still as laid out there is no advantage that I can see over facing all the LEDs forward.

It would be cool to see someone come out with a light that incorporates McGizmo's idea as posted above. I wonder why he never took that farther.:thinking:
