Since our founding in 1993, DONGHWA IND has grown alongside Korea's LED industry. Semiconductor leadframes, LED chips and packages, optical lenses, UV sterilisation — we deliver integrated solutions across the photonics, optics, and electronic components stack.
After incorporating in 2021, DONGHWA IND became the official Korean distributor for DOWA Electronics and continued supplying components as a partner to RUNLITE. Since 2024 we have added UV LED water-treatment equipment, followed by expanded domestic supply of DOWA SWIR LEDs and conductive GaAs wafers from 2025.
