Introduction: HARRY POTTER LED LAMP
For the basis of my lamp, I took the following work.
In my work, I increased the number of image layers and made the lamp portable with the help of batteries. And now I will tell about it in more detail.
For making such a picture you will need:
- Tumbler switches
- Soldering iron
- Box cutter
- Colored thick paper (200 g)
- Office paper
- Plywood (thickness 4 mm)
- Step Up converter (MT3608 2A Max DC-DC)
- 18650 battery
- battery holder
- black paint
- wood varnish
- plexiglas (thickness 2 mm)
- aluminum profile

Step 1: Image Selection
This method can make any image. In this paper, I used the image that I found on the Internet.
Step 2: Image Processing
In any graphics editor, the image is processed to achieve maximum detail contrast.
Step 3: Layering
After processing, you need to divide the image into layers. The number of layers is limited by the image of your choice and your desire.
Step 4: Paper Selection
The main parameters when choosing a paper are its thickness and color. From the thickness of the paper depends on the effect obtained when the LEDs work.
As an example, I will use one LED.
- Vellum is uniformly translucent and gives uniform diffused light;
- Office paper gives a muffled light;
- If you want the layer to not show through, you must take a thick paper.
You can use paper of the same color, but without the backlight, the picture will not look so impressive. In this paper, I used colored paper. By combining the colors of paper and its thickness, you can achieve amazing results.
Step 5: Transfer to Color Paper
After you have decided on all the options for your picture, you need to transfer each layer to paper. This can be done manually or using a printer.
Step 6: Cutting Image Layers
When cutting simple shapes, you can use scissors, but if the boundary of the layer has a complex contour, then I recommend using a stationery knife. With the help of a clerical knife, the edge is more even and neat. In very thin places I used a scalpel.
Step 7: Assembling the "sandwich"
After all the layers are cut, they must be assembled into a common block. To achieve the maximum image volume and the best illumination, each paper layer was laid with a plexiglass sheet of the size corresponding to the original image. To achieve a uniform glow, the back layer was glued with vellum.
Step 8: Backlight Adjustment
On the reverse side of the assembled unit, an aluminum profile was glued along the edge and an LED strip stuck onto it. Aluminum profile was used to remove heat from the LED strip. To achieve the color gradient, an LED strip of blue and white was used.
Step 9: Body Manufacturing
The lamp body is made of plywood to the size of the image, taking into account the overlaps for the location of batteries, microcircuits and other things. The back cover is attached to the case with 4 screws. The case is ground, covered with black paint and varnish.
Step 10: Electrical Circuit Assembly
An 18650 battery is used to power the LED strip, and to charge it, the microcircuit is controlled from overcharging and a micro USB connector. A voltage converter was used to power the LED strip, which converted the 3.7 volt battery into 12 volts necessary for its operation. This converter is not designed for long pieces of LED tape, but it will be enough for this job. To turn on / off the backlight switch was used. All elements were assembled as follows.
Step 11: Final Assembly
The final assembly includes the insertion of the main unit of the image, the final assembly of the electrical circuit, its verification and installation of the back cover. My camera doesn't quite convey colors. Live looks better.
Step 12: Final Result
The work is done. Thanks for attention!
