If you spend a lot of hours behind your desk in the evenings, than good lighting is crucial. Make yourself this ecological and economical efficient desk lamp.

The total cost of the 10w led lamp plus dimmer plus power supply =  26 dollar. All the other parts were laying around in my garage.

Step 1: Materials and tools


  • Four bolts M3
  • Four bolts M6
  • Four screws
  • Wooden board approximately 9 cm x 324 cm
  • Four dowels
  • Heat sink
  • Aluminum disk 20 mm
  • Led dimmer (Velleman MK 187)
  • 10w high power led
  • 12v, 1 amp power supply 
  • Thermal paste
  • Electric wires



  • Wood glue
  • Wood wax
  • Jig saw
  • Screw driver
  • Sand paper
  • Wood clamps
  • Drill
  • Drill bit  2,5 mm, 5 mm, 6 mm,  10 mm, 32 mm
  • Router
  • Router bit 12 mm
  • Solder
  • Solder iron
<p>I liike the modern design. But cost / benefit, would it be cheaper and more efficient to get an LED desk lamp. The Lumiy Lightline 1250 is only $50 so is that the better deal. </p>
buying and making one yourself are different things
<p>How could you dare comparing a beautiful and rare object of wood with a boring ugly lamp maybe not dimmable !</p>
<p>We have researched &amp; designed some new adjustable and dimmable touch wooden lamps, designer lights and craft lamps. Our products have acquired the CE-EMC, CE-LVD and CE-ROHS certification. For more information, we would like to let you know our company web site as below:</p><p><strong><a href="http://www.modenglamp.com/english" rel="nofollow">http://www.modenglamp.com/english</a></strong></p><p><a href="http://www.wooden-lamps.com/" rel="nofollow">http://www.wooden-lamps.com</a></p>
looking for inspiration, that is gorgeous...
<p>nice i will definetly try it :D</p>
like it
Thanks for posting this. Worked out great for a puzzle building lamp for the wife. Not as complicated as yours, but works great. <br>It won't let me post a pic of it but if your curious here's a link. <br>http://dalemoskalyk.wordpress.com/2013/08/26/finally-got-back-in-the-shop/ <br>Thanks again.
very elegant!
buddy, this is awesome... and the wooden box fan blew my mind too!
In step 2, how thick should the boards be after you glue them together? That step confuses me just a little bit (first project), do you mind going in to more detail?
Each wooden board is 9 mm thick, so 2 layers equals 18 mm and the total thickness (3 layers) equals 27 mm.
if anyone wants an outlet for leds and drivers, thecustomsabershop has what you need i believe.
hi so nice the design of the lamp, congratulations !! i like the minimalist concept of the lamp, and also that wooden detail to avoid the &quot;coldness&quot; of the strict minimalist things.. i oly have a disappoint , and is that you can do you own dimmer!! i have not so much time to post how to build one, but if someone makes a google search about pwm circuits ( i have found one that seems to me so simple to build, but i dont know if its ok to post it here, but google it and its the second) and that can do the job for the dimmer. instead of a motor, you can put the led , just bear in mind that you need a resistor for current control .<br>again , nice design <br><br>salutes from mexico
oh wow....this would be the perfect lamp for the desk in my scriptorium. i say 5* mate.
Great, but where did you get the LED, and where did you get the dimmer.<br><br>Thanks!
The 10w led is from ebay (just type 10w led) http://www.ebay.com/sch/i.html?_nkw=10w+led+warm+white&amp;_frs=1&amp;_trksid=p3286.c0.m359 . The led dimmer i got from a local electronic store, it is a velleman MK187 kit http://http://www.vellemanusa.com/products/view/?country=us&amp;lang=enu&amp;id=525683
I've never worked with an LED before, so it would be nice to know exactly what parts you used. But here is my real question. Does a 10 W fixture really need a heat sink? I know its in wood, but the residual heat has to be minor. Most of the electricity from the 10 W goes to light and only amount not converted to light becomes heat, or are these fixtures not as efficient as they claim?<br><br>
You would be surprised how much heat this led creates. The created heat is not a problem but the fact that the 10w led cant handle the heat is. If i would power the led without the heat sink the led will burn down after approximately 45 seconds. The bigger the heat sink the longer the lifespan. The commercial available heat sinks for the 10w led are even bigger than my CPU heat sink. If you don't like the big heat sink you can choose for cob leds they have better heat dissipation properties.

Which LED dimmer/driver did you use?
really great design. <br>simple and elegant.
That is simple, effective, flowing design. Just plain beautiful.<br><br>But, I think it need a wider &quot;base&quot; structure. <br>It's tall and a bit top-heavy. <br>You should add weight to the bottom or a wider base (or both)<br><br>Other than that it's a great idea and a nice build
Yes, Correct. The weight is more on top. <br>The base structure may also be cut 45 Degrees so as to get more footing and one kilo of weight added into the triangle base. That may keep the lamp steady. <br> <br>Since the advent of LED modules and dimmers, the imagination is the limit to create LED lights. <br> <br>FYI, all the incandescent lights at my home has been replaced with LEDS that give more illumination than the counterparts, less the energy consumption. <br> <br>Bravo good design. Thanks Harry. <br>
love the lamp and the fact you use items you find around the house, a true craftperson! <br>
Beautiful and simple. I agree, the heat sink can be shrinked. Make some convection holes as those will assist in the heat dissipation.
One commenter didn't like the screws holding the light.<br><br>May I suggest flat head phillips brass screws. I use them a lot in wood projects the brass goes very nicely with most woods. The flat head gives a very clean look.<br><br>Another nice looking screw would be the &quot;blackened flat head socket screw. It looks better with the darker woods.<br><br>As to the heat sink, be careful when reducing or shrouding the heat sink fins. Air &quot;MUST&quot; be allowed to circulate around and between them.<br><br>Another possibility would to design your own heat dissipation system. A large flat plate positioned slightly above the wood, using standoffs, might suffice.<br><br>The wax is a very nice idea.<br><br>I've use a product from &quot;Watco&quot;. It is an oil based product. I learned many years ago to wet sand it into the wood using 220 grit. With a little effort it produces a very nice &quot;feel&quot; to the wood while imparting a nice subtle color. Watco also has a product called Satin Wax that would be applied over the oil finish. This system would be more durable than using just wax. You could apply your wax over that for even a more lustrous finish. Oh, Watco also handles a &quot;natural&quot; finish.<br><br>All in all though, a very nice piece of work!
Beautiful lamp. Great instructions.. wish I knew how to do the electrical stuff..
its just so minimal and i like that, I think you should call it lambda lamp because of its shape
Thanks! But i am not sure to name it the lambda lamp :)
Nice design, it looks really sharp.
Wow! Simplicity at the best!
Thanks! Simplicity was my goal.
Great photos! I love the design of the lamp, too. I like that you just waxed the wood!
Thanks! I Just have a lot of wood wax and it is easy to apply.
Very nice. You could also use this design to make a document camera, using a webcam instead of the lamp.
I second that comment that you should call it the &quot;lambda lamp&quot;
Nice project. I really like the simple clean lines. <br> <br>only comments are that it would be nice if you could cut down the heat sink so that it doesn't protude so much. if it could be entirely withtin the thickness of the wood that would be best but i don't know if that's possible. i think if you widened the heat sink recess and used insulated washers so that the heat sink doesn't come in direct contact with the wood, then you could cut back the heat sink. heat rises so you should still get good heat dissopation. <br>it would also be nice if you could mount the light differenlty so you don't have the 4 exposed screws. i love how clean the knob is and would like the light to have the same simplicity. <br> <br>nice job!
