Mini Inverter 12v to 220v B22 Light Housing

thingiverse

I've designed a basic enclosure to house a mini inverter purchased from AliExpress, along with a bayonet B22 light fixture. My plan is to use these items for camping and portable lighting needs. I've printed and tested the enclosure using 3D printing with PLA material, and it's come out well. There are two different versions of the back panel - one serves as a simple cover, while the other has screw threads that allow you to attach it securely. Please exercise extreme caution when working with these devices, as they lack any safety features. To assemble this project, you'll need: Inverter link - $1.50 AUD delivered - available here: https://www.aliexpress.com/item/33038286159.html?spm=a2g0s.9042311.0.0.61c34c4dJx0psM Additionally, you'll require 2.5 x 5mm screws, which can be found on AliExpress in packs of 100 for around $2. The boards produce a high-frequency AC output as well as a DC 220v output. I'm using the DC output to power some LED lights that I purchased from Bunnings. My inverter has pin layout B and D marked as the DC outputs, but these are not labeled anywhere on the board. You'll need to examine the diodes of the bridge rectifier to determine which pins correspond to which outputs. When powering an 8.5W LED with a rated current of 800mA, I observed that approximately 12.2V was being drawn from the battery, resulting in a power consumption of around 9.5W. The board itself remained relatively cool, but the bulb did get quite warm. After testing for several hours, I found that the bulb didn't heat up enough to warp the PLA enclosure.
