Description
Matrix Lamp for 16×16 LED Matrix (WLED)
This Matrix Lamp is designed around a 16×16 LED matrix and an ESP32 controller, making it perfect for WLED animations, especially realistic-looking fire effects.
The lamp can be used in two different ways:
Standalone as a complete standalone matrix lamp.
Inside an IKEA GRÖNÖ lamp, where it creates a cleaner, more decorative appearance while improving the overall light distribution.
The Lamp was completely modeled by myself. The design was inspired by a WLED community project, but all CAD work and modifications were created from scratch for this model.
Required Parts
ESP32 D1
16×16 LED Matrix
5V 5A Power Supply
DC-025M (5.5 × 2.1 mm) DC Female Connector

For the Diffuser a White PETG Filament with 0,8mm Thickness was used.

Notes
The lamp was primarily designed to showcase WLED fire effects, but it also works great with plasma, gradient, and other animated matrix effects. The optional IKEA GRÖNÖ setup provides additional diffusion and gives the lamp a more premium appearance.
