LED PCB for General Lighting

I need a solid, production-ready LED PCB layout that will sit at the heart of a new general-lighting product. The immediate priority is the board itself: component placement, thermal management, trace sizing for consistent current delivery, and a stack-up that keeps costs sensible while still passing UL/CE safety checks. The board will eventually mount to a rotating assembly driven through a pancake slip ring and have supporting driver hardware, but those elements can stay in the background for now—design choices simply need to leave space for a 40 mm centre hole and provide clean, low-noise power contacts for the slip ring interface later on. What I will supply: • LED model and photometric targets • Mechanical outline with the slip-ring cut-out • Input voltage and dimming requirements What I expect back: • Schematic and annotated PCB layout files (Altium or KiCad preferred) • Complete Gerber/ODB++ package ready for fabrication • Verified BOM with part numbers in current distribution channels • Brief thermal and voltage-drop analysis showing the board meets lumen and temperature goals Please include a rough lead time and note any experience you have with circular or high-current LED boards—those examples will help me choose quickly.
