In this DIY project, I will assemble a 2K and 4K resolution projector using 3D printers and commercially available parts. I will provide a 3D print file when I am done.

Step 1:

Use 2 point LEDs: xhp70

Paste it on the 3D printing bracket with instant glue and sand the back with a sandpaper

Step 2:

Each LED needs to use a constant current power supply separately, set the voltage to 6V, and set it to a constant current of 4.8A or less.

Step 3:

Each LED needs to use a constant current power supply separately, set the voltage to 6V, and set it to a constant current of 4.8A or less.

Step 4:

It can be used as a flashlight after the battery is installed.

Step 5:

The interior of the 3D printed lampshade is sprayed with a reflective paint, and the Fresnel lens is placed, and the light source portion is completed.

Step 6:

It is already a handheld searchlight.

To be continued, thank you for watching
