LED retainer

thingiverse

This is a custom holder for COB LED chips designed to accommodate 26mm wafers, but can be easily modified to fit any size requirement. The holder secures the wafer to the steel plate within the armature, effectively transforming it into a heat sink that dissipates excess heat efficiently. I personally printed multiple units of this design to replace a malfunctioning fluorescent light in my workshop, leveraging the affordability and versatility of LEDs. Since these LEDs can be directly connected to AC mains voltage (230V) without any additional circuitry, they make an ideal choice for such applications. Four high-intensity 7W LEDs produce significantly more illumination than the 36W TL it replaces. Refer to: https://youtu.be/qGu0xiIVDNE
