Power Supplies for Industrial LED Lighting
Infrastructure LED lighting — tunnel systems, high-bay industrial and large-scale commercial installations — demands power supplies designed for continuous operation in harsh thermal environments. Off-the-shelf consumer LED drivers do not qualify.
What the Lighting System Needs
- Flicker-free output — critical for tunnel safety and industrial work environments
- High power factor (>0.95) to meet building regulations and utility requirements
- Low THD for compatibility with generator backup systems
- Wide dimming range without flicker or instability at low levels
- Operating temperature up to 70°C for enclosed luminaire housings
- CE, RoHS and UL certification
How Sudtech Approaches It
Sudtech has supplied LED drivers to lighting manufacturers deploying in tunnel infrastructure and commercial high-bay environments. Our design team works from the thermal model first — a driver that cannot survive 60°C inside a sealed housing is not a solution, regardless of the datasheet rating.
We handle the full certification process in-house. Dedicated certification engineers manage every application from submission to approval, so lighting OEMs can focus on optics and controls rather than compliance paperwork.
