Precision engineering and volume LED manufacturing
cesw operates specialized SMT placement lines and optical testing facilities to supply certified industrial luminaires for global commercial and infrastructure projects.
Industrial production infrastructure and engineering depth
From high-speed surface mount assembly to custom aluminum die-casting, our production floor is optimized for volume throughput and tight mechanical tolerances.
Automated SMT & assembly lines
High-precision surface mount placement lines equipped with automated optical inspection ensure consistent solder joints across every high-output LED board.

Optical & thermal simulation
In-house optical engineers utilize advanced photometric and thermal modeling software to optimize beam distributions and heatsink heat dissipation.
Rapid tooling & prototyping
Dedicated CNC milling and modular mold tooling deliver customized structural prototypes and photometric test samples within 7 to 10 business days.
Rigorous multi-stage quality control and compliance
Every production lot undergoes comprehensive electrical, photometric, and environmental stress screening prior to dispatch.
1. Incoming raw material screening
100% inspection of high-grade aluminum extrusions, Tier-1 LED chips, and premium surge-protected drivers against strict mechanical and electrical specs.
2. In-line optical & thermal checks
Continuous thermal imaging during high-speed SMT assembly verifies heat path integrity before driver housing integration and mechanical potting.
3. Full-load burn-in aging
Every assembled fixture runs continuously for 4 to 8 hours under high thermal load to eliminate early-stage component drift or power supply faults.
4. Certified lab verification
Goniophotometer lumen output validation and high-voltage dielectric withstand tests confirm complete compliance with DLC 5.1, UL 8750, and CE directives.
Market access certifications for North America and Europe
Our fixtures hold formal certifications and test reports required for municipal projects and commercial utility rebate programs.
