Review rule: if a dimension is not on the drawing, it does not go in the article.
Sobre
Weili Wu is Engineering Lead at Helian LED. He has spent seven years in LED industry structural design — extrusion sections, thermal paths and mounting interfaces — and is responsible for the technical accuracy of every profile dimension, mounting method and installation sequence published on this site.
Before a guide is published, he checks each figure against the extrusion drawing and the actual section. Where a drawing and a draft disagree, the drawing wins.
Educação
Mechanical Design, Manufacturing and Automation — Guilin University of Aerospace Technology.
What he reviews
- Profile dimensions, tolerances and PCB widths
- Mounting methods — recessed, surface-mounted, suspended and corner
- Thermal management, wall thickness and material specification
- Installation sequence and compatibility of end caps and connectors

Products he has worked on as structural designer:
Série Smart Puzzle
Square, rectangular and hexagonal modules of different footprints share one connector and one suspension interface, so a layout can be assembled on site without extra parts. The structural work sits at the joints: every seam has to carry load, pass the light engine through, and close cleanly on the visible face.
HL-UA046-L12
Two optical chambers share a 54 mm wide extruded section, and the up-down ratio changes without changing the housing. Structurally the same section has to separate the two light paths, carry three wattages, and keep the suspension points inside the load path of a 1200 mm body.
