History
About company
Global leader in LED technology, Writing a new history with light.
We are a global LED company based on the world's first No Wire WICOP technology.
Seoul Viosys is a full-line solution provider for UV LED, VCSEL (Vertical Cavity Surface Emitting Laser), the next-generation light source for 3D sensors and lasers and a single-pixel RGB “WICOP Pixel” for displays.
Established in 2002 as a subsidiary of Seoul Semiconductor, it captured the leading market share in the UV LED industry (LEDinside, 2018). Seoul Viosys has an extensive UV LED portfolio with all wavelength ranges (200nm to 1600nm) including ultraviolet rays (UV), visible rays and infrared rays. It possesses more than 4,000 patents related to UV LED technology. Violeds, its flagship UV LED technology, provides a wide range of industries with optimal solutions for strong sterilization and disinfection (UVC), skin regeneration (UVB), water/air purification and effective cultivation for horticulture.
In 2018, Seoul Viosys acquired RayCan, a leading optoelectronic specialist, to add the advanced VCSEL technology which supports smartphone facial recognition and autonomous driving, and has begun mass production.
Founder’s message
For a new history of light! And a world without technology theftFor a new history of light! And a world without technology theft
Every day we reflect on the day's work and keep moving forward one step at a time to adhere to our principles and create value for our valued customers who share values with us.
With the goal of “making the world cleaner, healthier, and safer with light,” Seoul Viosys has grown from a rental factory on a commercial street - by turning crises into opportunities - into the world's only company that has second-generation technologies in the LED industry to produce optical semiconductor LEDs of all wavelengths, from 20nm UV to 1400nm laser diodes, without wire, package and lens, which are essential elements of semiconductors. We will strive more vigorously to provide mankind good light – a healthy light that prevents myopia onset with natural light, a clean light that clears viruses and bacteria from the air and water, a memory-improving light, a light that reproduces natural colors and a light that helps you have a good night's sleep. In my 20s when Jimmy Carter, a son of a farmer, became President of the United States, I asked myself “What about me?” as I was also born the youngest son of a farmer. Just as this was a turning point in my life, I hope that the journey of a company that started business in Korea but has grown to become a global manufacturer will be a small but sure hope for young people. Just as intellectual property motivated the world to spark the First, Second, and Third Industrial Revolutions, reducing the proportion of the world's population in absolute poverty from 85% to less than 9%, giving people light by which people obtain 80% of information, lowering the illiteracy rate from 90% to the 10% range and leading people to a safer life, and reducing infant mortality from 44% to less than 4%, respecting and honoring intellectual property rights will give hope to young people, accelerate creative innovations, make human life better, and create a fair society where people can move between social classes. To help make this hope a reality, I keep creating new works and fighting for intellectual property, vowing not to cut my hair until I have won each battle. Please show your continuous interest in us and keep encouraging us in the future.
