Swap Lamp for Walls (Halloween/Pumpkin Version)

Swap the lamp for a new style for any occasion. This version is a pumpkin themed lamp. Other versions available for swaping:

• Modern version: https://www.printables.com/de/model/41740-swap-lamp-for-walls-modern-version
• Winter / christmas version: https://www.printables.com/de/model/623133-swap-lamp-for-walls-winter-version-herrnhut-star

Disclaimer

This lamp requires the skill to work with mains voltage (230V/110V). If in doubt, ask a professional (or your parents if you are underage) how to work safely. The author of this manual will not take any responsibility or liability for any damages to person or property caused by improper safety precautions or the installation of the described lamp.

Required materials (full build)*

• 2x LED driver, constant current source, input 230V/110V, output 700 mA
• 2x High Power LED 700 mA star
• Transparent PETG filament for the “lenses"
• A filament for the electrical part (see “modern lamp”, Prusament PLA Galaxy Black was used in this example)
• Two filaments (orange and green) for the pumpkin part (Prusament PETG was used)
• 2x two pin connectors male and female each. The model is optimized for the connectors shown on the pictures.
• Super glue/cyano acrylate/any other transparent fast setting glue which adheres to your filament.
• Wire (should be thick enough for 700 mA and thin enough to fit into the carrier

*: if another version of the Swap lamp is already in place the constant current source is already mounted and you know most of the thing below already. This will be easier then.

Instructions

1. Please find the files for the wall mounted base and the mounting description in the “modern version” of the lamp-set: https://www.printables.com/de/model/41740-swap-lamp-for-walls-modern-version
2. Use the files “connector” and “lamp-base” from the "modern version" of the swap lamp series. Print those files in any filament you like. In case you plan to use other lamps for swaping consider to use a darker color (Prusament PLA Galaxy Black) as in some versions of the lamp this part can be seen very well (modern version)

Skip when a wall mount is already present from another version of the series

1. Prepare the constant current LED driver by cutting and stripping the cables. Cramp the connectors to both sides. Use female connectors on the constant current source to prevent short circuits. If no cramping equipment is at hand solder the joints.
2. Prepare the wall base (file in “modern version”) by gluing the constant current driver and the female connectors in place.
3. Check your local regulation, since in some countries working at mains voltage is only allowed by professionals. If you want to attach the power yourself, check your safety precautions. Open/remove the power fuse so you do not work on live wires. Prevent the fuse from being reset.
4. Check for cables or studs, drill holes and screw the lamp base to the wall. Connect the constant current sources’ input to the mains power line.

Continue here, in both full build or "new version build"

1. Prepare the connector (file in “modern version”) by deburring if necessary. Test fit the connector to the lamp base. If the connector does not slide with low (to medium) force, use a deburring tool or some sandpaper to improve the fit. Spray the two guide rails with silicone spray to improve sliding (optional).
2. Glue the (orange) base (file in this version) on the (galaxy black?) lamp connector (file in “modern version”).
3. Solder the High-Power LEDs to their power wires. Do not solder the High-Power Leds when they rests in their printed sockets since the sockets will melt from the heat. After cooling down, carefully pull the wires through the two holes in the lamp base/connector part (see above) and glue the LEDs into their sockets.
4. Solder the male power connectors (check polarity), mount the parts on the wall and test for connection. In some cases the leads of the male power connectors need to be bend a little to create a good fit. Continue, when the electrical connection is reliable.
5. Glue the transparent diffusers together. They should look like two halfed eggs with ventilation openings at the bottom and the top. You only need to glue one seam (the side which is on the print bed in the diffusors.3mf - file). If you intend to glue two seams per diffusor, you are doing it wrong. Glue the diffusors on the lamp base so the light of the two LED will be diffused and does not cast shadows.
6. Glue the pumpkin to the previous part (lamp base with connector and lens/diffusor). You might want to check the alignment first, so your pumpkin is not crooked in case the wall mount was not mounted perfectly straight (this is the case at my home).
7. Glue the two parts of the stalk together. Then glue the stalk to a position of your choice on the the pumpkin head
