Trusted Supply, World-First Technology – Seoul Semiconductor at LFI 2025

SEOUL, South Korea--Seoul Semiconductor Co., Ltd. (KOSDAQ: 046890), a global leader in optical semiconductor technology, will participate in LightFair International 2025 (LFI 2025), held from May 6 to 8 at the Las Vegas Convention Center. Leveraging its global production network, Seoul Semiconductor offers a stable and reliable supply system and will unveil several of its world-first LED technologies at the event.

At LFI 2025, the company will present three key innovations:

• SunLike: A natural sun spectrum LED that contributes to eye health and improved sleep quality by closely mimicking natural sunlight.
• WICOP: A compact, high-reliability LED technology with no wire, delivering enhanced durability and energy efficacy.
• Acrich: A high-voltage LED solution that connects directly to AC power, providing exceptional design flexibility and system simplicity.

Since its founding, Seoul Semiconductor has consistently reinvested approximately 10% of its annual revenue into R&D, resulting in over 18,000 patents—a testament to its continued leadership and innovation in the LED industry.

With manufacturing sites across the United States, Korea, China, and Vietnam, Seoul Semiconductor has maintained 100% on-time delivery even amid global supply chain disruptions such as the COVID-19 pandemic. The company remains committed to its core value of customer trust, further strengthening its global production and delivery capabilities.

A company representative stated,

“Thanks to our advanced technology and robust global manufacturing capabilities, we have built deep trust with customers across diverse industries in North America.
