30 Watt Led Worklight





Introduction: 30 Watt Led Worklight

This is my try to replace the energy-hungry 150watt halogen floodlight I use for working on my lathe.
I think it went well..

Step 1: The Parts

The basic components and electronics are from DealExtreme.com
 the led
the driver
the optics
  a PVC pipe, a pipe holder, a p4 heat sink and an old 24volt fan.

I suppose that connecting the led to the driver and mounting it on the heat sink with the optics is self explanatory so the photographs are enough.

Step 2: Test Fitting

Mounting the heat sink in the pipe at the front and making sure everything else fits.

Step 3: The Holder

I took the one piece of the pipe holder,the one with the bold on it, straightened the sides and found a screw for the bolt.
 I also made an L shaped bar to mount on the wall. Test fit everything using a rod passing through the pipe with a couple of spacers.

Step 4: Tidying and Painting

Since everything fits fine, I made connectors for the fan and led, some heat shrink  for protection, some wire protection and of course some tape for isolation.
Then for some painting.Primer first and then black paint.

Step 5: Putting It Together

After the paint has dried up, I cut the center rod to length and found 2 bolts to secure it on the pipe holder. 

Step 6: Comparison

Installed both lights for a comparison.

    I've got the spare heatsink from my new i5 processor (got a much bigger one so I could overclock) and thought it would make a great heatsink for a 100watt led from dx. ...Just can't fathom for the life of my why I need 100 watts of led, except perhaps to replace my projector bulb when it dies.

    We NEED 100 Watt LEDs because they are available and WE CAN.

    If we couldn't, then all advances in technology would die off and it would be such a dreary place....

    Who wants to live in a hell-hole where nobody can do anything, much less think outside (or inside) the box and make fun stuff?

    Don't get me wrong, I'd love one, just I don't NEED one. On the grounds of 'just because', I have too much crap. I buy/build/mod everything, and now have literally thousands of projects that I have no use for.

    SO! You're the guy that filled my garage with all that stuff?

    I have a belligerent drunk neighbor that forgets where the property line is on a regular basis so I build high power IR LED floodlights so the DA and Sheriff can go talk to him after they view the videos.
    I saw a 3 million candlepower IR light on a chinese website, but I don't wanna blind the guy....

    Actually, because it's IR, it would be more likely to fry him than blind him! Bwahaha!

    Because it is dark, his pupils are wide open AND IR is a light wave and can cause damage to the retina.
    Safety first... second, third, etc.... ;=}

    Good thinking but no, your corneas are pretty much opaque to IR wavelengths longer than about 800nm. 3 million candlepower just might set fire to his house though :>

    The hell-hole would be never being satisfied, always thinking you have to do some difficult thing just to get by when others don't waste away their time on such things.

    For the LED controller why did you use tape? you can get 4 inch diamater heat shrink online that will fit over then shrink around it making a better "case" and it might look nicer.

    Because i wanted one side open so the draft from the fan could cool in some.Not that it needs it but since it was possible I did..
