High-Efficiency LED Commercial Lighting Drive Solution
LiTong Group offers a high-efficiency LED commercial lighting drive solution, designed to meet the stringent performance and regulatory requirements of modern commercial and industrial lighting applications. This solution leverages Power Integrations' advanced LYTSwitch™ and LinkSwitch™-PH LED driver ICs to provide reliable, energy-compliant, and cost-effective lighting systems.
Commercial lighting demands not only high efficiency and reliability but also excellent power quality (high power factor, low THD) and often dimming capabilities. Our solution addresses these needs by integrating highly optimized LED drivers that simplify design, reduce component count, and ensure long operational lifetimes for LED luminaires, contributing to significant energy savings and reduced maintenance costs.
