After a long cold winter, the sunlight is getting warmer and we enjoy to go back outside: the first flowers blossoming, the birds singing, … This atmosphere of springtime inspired me to create a new table lamp.
This lamp is easy to make and cost around 30 dollars.
Step 1: Materials and Tools
- Wooden sticks (10 mm in diameter)
- Decorative glass egg
- 10w LED heat sink (110 mm in diameter, 17 mm high)
- Bridgelux Micro SM4 LED (BXPX-27G0400-B)
- 700 ma LED-driver (wall plug type)
- two screws M2
- Wood glue
- Solder iron
- Thermal paste
- Bar clamps
Step 2: Sawing and Sanding
Start by sawing the round wooden sticks in to approximately 10 cm pieces.
You can use any saw suitable for wood to do so. I used a small handsaw.
I sawed around 55 pieces. But you could end up with more or less pieces.Next, sand both ends of every piece with 240 grid sand paper.
Step 3: Gluing
Make two squares with the wooden sticks and glue them together using wood glue.
Glue the two squares on top of each other so that it looks like a star. This gives a good base for the heat sink to rest on.
Make four triangles by gluing each stick on top of the other. Glue each triangle to the star shape base in a 45° angle, use bar clamps to hold them together. Note: you don't have to glue them precisely in a 45° angle it is just an indication.
From now on you can just randomly glue the remaining sticks on and through the base to create the nest shape.
Step 4: Installing the Light
Cut the cable of the led driver roughly 1/3 from the end in half.
Solder the “cut of cables” to the LED.
Use two M2 screws to attach the led to the heat sink. Do not forget to put thermal paste between the LED and the heat sink for better thermal management.
Place the LED + heat sink on the bottom of the nest. Put the wires between a couple of sticks.
Open the housing of the switch and screw the wires in place. One wire will be interrupted by the switch while the other one continuous. Screw the housing back on the switch.
Step 5: Finishing Touch
Place the decorative glass egg on top of the heat sink, find a nice spot to place the lamp, push the switch and you are finished.
