Logitech C920/C920S Ring Light

I needed a reliable lighting solution for my video conferences that would withstand all-day use. My desk has windows directly behind me, and the natural daylight consistently overpowers the image on camera. Since ring lights are pricey, I decided to repurpose an old dimmable LED strip from a previous project. I designed a frame to hold the LEDs in place. The LED strip and dimmer I used can be found at https://www.amazon.com/gp/product/B00MHLIFO8. Based on other DIY projects and user feedback, I initially thought it would be necessary to include a sheet metal backing to dissipate heat generated by the LEDs. However, after assembling and testing my setup, I've come to realize that the metal backing is not required. The LEDs produce minimal heat, and it's likely safe to attach them directly to the plastic without any additional support. My design involves placing LEDs in a circular pattern beneath a diffuser. The kit consists of two parts specifically designed for Logitech C920/C920S cameras. This idea was inspired by Eunchan Park's light ring on Thingiverse (https://www.thingiverse.com/thing:2814571). To assemble the lighting kit, simply print the ring base in any color you prefer and the diffuser in a tone or color that matches your desired lighting effect. I chose white for my setup. You can also experiment with layering multiple colors on top of each other, but keep in mind that the diffuser is relatively thin.
