Introduction: Simple Looking LED Wall Light

My little sister needed a new wall light for her dressing.
She asked me to give it the looks of a spotlight with the wide beam angle of a regular light.
The result is this wall light.

The total cost was around 35 dollar.


Step 1: Materials and Tools

Materials

  • Wooden board (MDF 12mm)
  • LED (BRIDGELUX - BXRA-W0401-00000 - ARRAY, WARM WHITE, 400LM)
  • Power supply (12v)
  • LED driver (700ma)
  • Opal glass
  • Round pinfin heat sink (80 mm)
  • Two screws (M3)
  • Two wall plugs
  • Two hook screws

 

Tools

  • Pair of compasses
  • Solder
  • Solder iron
  • Paint
  • Paintbrush
  • Screwdriver
  • Drill
  • Diamond drill bit (40 mm)
  • Drill bit (45 mm,  40 mm, 6 mm)
  • hole saw (90 mm)
  • Jigsaw 
  • Miter saw
  • Glue gun
  • Wood glue
  • Bar clamps

Step 2: Drawing

Start with two pieces of 10 cm by 40 cm. and one piece of 8 cm by 1 cm

The material I used was MDF (12 mm thick).
I had them precut at a local wood shop, but you could easily saw them yourself from a bigger piece.

Take the two 10 cm By 40 cm  pieces and make a mark from each end straight in the middle at 5 cm.
Take a pair of compasses and draw a half circle  (10 cm in diameter) on each mark.

 Take one piece and draw a line 1 cm from the edge of each long side.

Draw a line in the middle of each piece from the long side to the opposite long side.

Step 3: Sawing, Drilling and Gluing

Use a jig saw to saw the half circles out.

Take the piece with long straight lines and drill 90 mm holes on the markings.

Drill a 40 mm hole, 9 mm deep on a marking of the other piece. Drill a 35 mm hole on top.

Take the piece with the 90 mm holes and saw the inside out (use a jigsaw).
Use wood glue to glue the two pieces together. 
When the glue is dry saw the hole piece in half, than saw a 12° angle on each piece.

Glue these pieces back together.
Glue the 1 cm by 8 cm  piece in place: see picture (where the two pieces meet on the piece with no hole).
This serves to fix the lamp to the wall.

Step 4: Sanding and Painting

Properly sand the hole piece.

After sanding you can paint your lamp fixture in any color you like. I chose white.

Step 5: Heat Sink

The heat sink I bought  had no holes to attach the LED to the heat sink.

Draw a straight line on the flat side of the heat sink. Shift your ruler to decide where the middle is. This isn't the most precise way to determine the middle, but it will do the job. 

Place the LED on top of the heat sink and make markings where the screws will be placed.

Drill a 2,5 mm hole 4 mm deep on the markings.

Step 6: Power

Solder the driver to the LED. Make sure the polarity is correct and don't burn the LED.
Screw the LED to the heat sink.

Installing the driver to the power supply.

The power supply didn't fit in the lamp fixture by a few millimeters, so I removed the outer case.

Use a glue gun to glue the power supply  in place.

Connect electrical wires to the output of the power supply.

Solder these wires to the input of the LED driver.

Step 7: Glass Work

The glass plate I got from my local hardware store. It is opal glass

Use a 40 mm diamond drill to cut out  a glass disc.

Lay the glass disc in the 40 mm hole  of the lamp fixture.

Now place the heat sink on top of the glass plate and fix it with a wood screw.

Step 8: Wall Mounting

Drill two holes (6 mm) in to your wall at the desired height  spacing them 6 cm from each other.

Put wall plugs in to these holes and screw hooks in to them.

Attach the electrical wires coming from the wall  to the input of the power supply.

Be careful: make sure the power of these wires is off.

Attach the lamp fixture to the hooks. 

Step 9: Finishing

I hope my little sister is happy with her new wall light.

Thank you so much for your idea and instructuable.
I built your lamps, but I modified them a bit...
I personally had some problems with the painting, my lamps aren't that smooth and clear as yours.

The LEDs that you use is Superbright LED. to make that lamp be smooth and clear ,you can use 1 watt or 3 watt or 10 watt and place a thin diffuse plastic

Nice, very impressive to say the least. DIY projects like this would have been hard to do with regular light bulbs. Here's a article about beam angles that might help in deciding which type of LED to get http://goo.gl/QCJul

Beautiful light. Our bed is under the window so there is no easy to put in reading lamps. You have solved our problem. Thank you. You've got my vote

very simple yet exteremly elegant design,the smooth finish is probably the secret behind the beauty of this thing,wondeful job to say the least, i assume you left too much free space inside the enclosure of the lamp because you didn't want to make it narrow cuz it could easily accumulate heat that way?,this may not apply here since we're talking about a lamp, but you can consider the free space in other instructables,really cute design

Definitely not UK, the colours of the cables are wrong, and I think this is sailing a little close to "Part P" legislation which is intended to prevent un qualified people from doing shoddy work but mainly prevents people from doing a lot of DIY projects. Technically you are allowed to change an existing light fitting with one made for the purpose, but making one yourself may require the services of an inspector to certify it as safe. A requirement which adds about £200 to your project. Sad isn't it?

Hi,

a really great job.
Could you please add the link to know where buying the LED and the driver.
I do not really know where to check to find the ggod one and as my electronic knowledge is too poor I really need to know where buy the good one. ;-)

Sincerely thanks and have a nice day,

Miguipda ;-)

Does the LED really need the heat sink? I have a flashlight that has (9) 10mm ultrabrights in it and it doesn't even get warm.

Exactly my thoughts, and all his stuff is 220 v. . UK ?

I think to simplify this, I'd just take apart one of those 99cent 9 LED flashlights and then mount it into the housing plus a light switch.

If you use the LED like described in the materials list you certainly need a heat sink.
The led consumes around 6,65w and will burn down after just 10 seconds without a heat sink. The lamp is designed to fill up a room with warm white quality light. If you use the small LED's from a flashlight you don't need a heat sink but you don't have the same light output and quality as for example the high power LED that I used.

Wow! I love your lamp in its simplicity and beauty. I will definitely use the inspiration for a similar build.
