It also saves energy storage units (e.g. electrolytic capacitors, transformers, etc.) and high-current power devices (e.g. power transistors, MOS transistors, etc). Consequently, it reduces driving loss and increases power efficiency. The lifespan of driving can truly match that of LED beads. Under good heat-sink management system, the lifespan of LED high bay luminaire can wholly achieve 50000 hours and above. Q: The LED High Bay luminaire with AC direct driving technology is non-isolated, so is it safe?A: Most of the low-power LED high bay lights on the market which have switching power supplies use non-isolated topology. After all, isolated switching power supply is relatively lower in efficiency, larger in size and more costly in expenses. Additionally, 100% of our AC direct driving high bay lights meet the safety standard and strengthen insulation test. Q: Can your AC direct driving high bay luminaire be accepted by the market in terms of beam flicker?A: To date, there's no proof that 100Hz beam flicker is harmful to human body. Our products have all passed Japan and US LED standard. Besides, we also have no-flicker solution which adds up electrolytic capacitors and have passed CCC, CE certification. ==================================================================================Our Core Competence 1.Technical platformSupported by CAS (China Academy of Sciences), USTC (University of Science and Technology of China) and Advanced Technology Institute of USTC, we have perfectly integrated G13 technical solution into our high luminous efficiency modules of EPC (Energy Performance Contracting. 2.Product Core TechnologyA.Simple, Truly Energy-Efficient and Endurable: Simple and lower cost: No switching power supply, save installation of driver and power box. Truly Energy-Efficient and Endurable: Compared with regular LED luminaire, our AC direct driving LED high bay has higher luminous efficiency, higher power factor, higher optical conversion ratio, lower lumen depreciation (LD) less operating current and longer lifespan.It has less than 3% lumen depreciation per year, and less than 20% lumen depreciation for 8 years. We are truly green and energy-efficient!B.Safe, Reliable and WarrantyAll high bay lights are designed as wide voltage range and with OPC (overvoltage protection circuit) in order to adapt voltage fluctuation and different regions. Our LED high bay luminaire has varistors to avoid thunder and surge, has fuse to protect from over-current and over-heat. Insulation thermal film to prevent leakage. And they all passed CE, CCC, RoHS, UL, FCC certification!Control of Temperature Rise : 40 °C, MOS transistor and IC are mounted separately to ensure IC stable operation.Warranty: As long as five yearsC.Global sole agent of AC direct driving technology by CASD.Industry Trend: AC direct driving LED high bay is an irreversible trend, it will definitely become the mainstream product on the market in near future!
