Cardboard Pentagon Table Lamp

In this project, I make a big lamp out of cardboard.

I choose pentagon shapes for lamp geometry.

I got lots of cardboard in waste. I made this lamp big in size compared to a regular lamp.

The lamp looks like a pentagonal globe that is illuminated by light from inside.

Let’s start making this lamp.

Gather all supplies listed below to start making.

1> cardboard (approx. 3 ft x 4ft sheet) or use waste boxes of home appliances

2> Scissor

3> Glue

4> scale

5> glue gun

6> LED light

For making the pentagon shape we use different sizes of rectangle cardboard.

We use below the number of cardboard pieces.

1> 80 x 20 mm x 55 piece

2> 100 x 20 mm x 55 piece

3> 130 x 20 mm x 55 piece

4> 150 x 20 mm x 40 piece

5> 175 x 20 mm x 40 piece

6> 200 x 20 mm x 20 piece

7> 400 x 200 mm x 1 piece for center pole.

Use a scissor or paper cutter to cut the cardboard.

For cutting all sizes of cardboard pieces, first, you cut the longboard as per different heights.

Then mark 20 mm spacing on each cardboard to cut with a scissor or paper cutter.

Cut them and store them separately.

For making the base we use the below rectangle cardboard cuttings.

1> 200 x 20 mm x 20 piece

2> 175 x 20 mm x 40 piece

3> 150 x 20 mm x 40 piece

Arrange them in a pentagon and use glue to stick them one by one as shown in the images.

Make a bunch of them and place one on the other to make the whole base.

For making a small pentagon we use below cardboard rectangle strips.

1> 80 x 20 mm x 55 piece

2> 100 x 20 mm x 55 piece

3> 130 x 20 mm x 55 piece

We arrange each size of cardboard stick in a pentagon and make 3 different layers of a pentagon with different sizes of a pentagon.

We make 11 staked pentagons using these 3 different-sized cardboard rectangles.

Stick all 11 pentagons one by one from each side of the pentagon edge.

Starting from 5 sides of the pentagon. stick 5 pentagons on base.

After drying stick the other 5 pentagon shape on other edges.

Lastly, stick 1 pentagon at the top side of the structure.

Use 400 x 200 mm x 1 piece for the center pole. Bend in 3 pieces to make a triangular shape.

Use lights to stick around the triangle Pole.

I use an RGB LED strip but you can use a white LED for a single color of light.

To assemble the pole we cut cardboard of the same size as the bottom and placed the pole in the center of the bottom plate and join it with adhesive.

Connect the base with the top lamp structure and your lamp is ready.

On power supply and check out how it glows at night time.
