Yet another aspheric thrower

Well, not yet

And many light-years away. too!

:open_mouth: :smiley:

hahaha true!

Nice!

A flashlight with a Noctua fan...

It would be interesting to see how much relative output the LEDs looses over time due to heating up.

You monster. I’ll have to keep my eye out for a build thread :wink:

Ah true, I could take several lux measurements over time.
When I did the intensity measurement I waited a few minutes before taking the final reading.

:wink:

It’s impressive to see what you can do with only 3 screws. :smiley:

Isn’t it this one ? : Received the second component of my future project

Yeah I haven’t had time to machine the piece of metal I need to hold and cool the crystal and laser.
Hopefully once school starts in september and i have access to the machine shop again :slight_smile:

That’s pretty slick! Like a laser beam!

Thanks :smiley:
I like fat lasers

What’s the power output on the led, like volts/amps?

It’s running at 6A and about 3.7V, so ~22W
With three high capacity 18650s it would run about 1 or 1.5h on max

That’s a lot of power through that tiny led! Good to see it’s fan cooled.

Ok now that is ridiculous

It’s not much compared to the 200W that the CFT90 was running at in my syniosbeam build :stuck_out_tongue:

:smiley: thanks

You are one crazy dude Enderman.
Keep it up. :slight_smile: :beer:

Thank you :smiley:

Enderman i have some questions for the throw master. i know that the collar directs the light back onto the led but does depth of field and size of the aperture have anything to do with throw?

Do you think the collars could be made by cutting a hole in one of these Aliexpress with a diamond hole saw?

The size of the exit angle will change the amount of light recycled.
With a larger exit angle, the collar is collecting less light, which means you will get a higher efficiency from the LED (more lumens output) but less intensity because there is less light being recycled.
The wavien collar with 60 degrees full angle is an arbitrary middle ground, collects 75% of light, with a 33% recycling efficiency, resulting in 25+25 = 50% of the total LED light being output through the opening at 2x the original intensity.

Yes you can make your own collar with a spherical reflector and a diamond saw if you’re very careful.
That reflector you linked will not work because it is parabolic.
You need a hemisphere.

Small like an EDC

Great :+1:

Hahaha thanks :stuck_out_tongue:
A lot more portable than my previous builds!
