Step-by-Step Assembly Instructions:

1. 3D Printing the Parts

• Print the following files in this order:

1. lamp.stl

2. base1.stl

3. base2.stl

4. battery.stl (if using a battery).

• Ensure clean edges and verify proper fit of each part after printing.

2. Connecting the Circuit

• Important Tip: Perform all soldering on the circuit board before placing the components in their designated slots.

1. Solder the LED strip’s positive and negative terminals to the corresponding poles on the circuit board.

2. If using a battery:

• Solder the battery connections to the circuit, ensuring polarity is correct.

• Cut a piece of copper adhesive tape, attach it under the circular design at the base, and solder it to a wire.

• Connect this wire to the designated input on the circuit board as per the manufacturer’s instructions.

3. Assembling the Lamp

1. Insert the lamp.stl piece into the base1.stl. Use a small amount of glue to secure the connection firmly.

4. Installing the LED Strip

• Slide the COB LED strip into the lamp piece’s 225mm channel. Ensure it fits snugly.

5. Mounting the Circuit Board

1. Place the circuit board into its designated slot inside base1.stl.

2. Apply a small amount of glue to secure the board, then use the two M2*4 screws to fasten it for added stability.

6. Installing the Battery

• If using a battery:

1. Place the battery into the printed battery.stl holder. Secure it in place using glue.

2. Insert the battery holder into the base, ensuring proper alignment.

7. Final Assembly

1. Attach base2.stl to base1.stl to close the base. Ensure everything fits securely.

8. Charge Indicator Setup

• Align the pre-installed red and green LEDs on the circuit board with the hole in the base for charge status indication.

Usage:

1. Activation: The lamp is activated by touching the base where the copper tape is attached. Depending on the circuit used, dimming functionality may also be available.

2. Charging: Recharge the lamp via the USB-C port. The red LED indicates charging, and the green LED indicates a full charge.

This project combines 3D printing, electronics, and soldering, making it ideal for hobbyists and DIY enthusiasts. Happy building!

Step-by-Step Dettalied Procedure for Assembling the Lamp

Step 1: Attaching the Lamp Post to the Base

1. Apply a small amount of glue inside the slot at the top of the base (base1.stl).

1. Insert the lamp post (lamp.stl) into the slot and press it firmly.

1. Allow the glue to dry completely to ensure stability.

Step 2: Preparing and Soldering the LED Strip

1. Solder the positive (+) and negative (-) wires to the COB LED strip.

1. Ensure the solder joints are clean and secure for proper electrical connection.

2.  

Step 3: Connecting the Circuit Board

1. Solder the battery wires to the terminals on the circuit board, ensuring the polarity is correct (+ and -).

1. Connect the LED strip wires to the appropriate terminals on the circuit board as per the manufacturer's instructions.

2.  

Step 4: Attaching the Copper Tape

1. Cut a piece of adhesive copper tape and solder a wire to it.

1. This copper tape will act as the touch-sensitive area for turning the lamp on and off.

2. Connect the wire from the copper tape to the designated input on the circuit board.

Step 5: Installing Components Inside the Base

1. Insert the LED strip into the channel inside the lamp post. Ensure it is aligned and fully inserted.

1. Place the circuit board into its designated slot inside the base (base1.stl) and secure it using small screws or glue. Test the hole before.

Step 6: Fixing the Battery Holder

1. Apply glue to the battery holder (battery.stl) and attach it inside the base in the designated area.

1. Insert the battery into the holder and secure it to prevent any movement during operation.

Step 7: Final Connections and Closing the Base

1. Verify that all wires are securely connected and the copper tape aligns with the touch-sensitive area.

1. Attach the base cover (base2.stl) to seal the assembly.

1. Ensure all components are properly positioned inside before fully securing the base.

If you wont glue the LED COB to the base to prevent any movement.
