In 2014, LED technology gradually made its way into millions of homes. From indoor lighting to urban landscapes, LEDs became a common and essential part of everyday life. Before that, some people doubted whether this technology could ever be realized, but now it has become the leading force in the lighting industry.
While many are familiar with LED lighting, fewer have heard of laser lighting. In 2016, Nobel laureate in physics, Shuji Nakamura, boldly predicted that laser lighting would replace LED lighting within the next decade. Who could have imagined that just one year later, a domestic laser expert would turn this vision into reality?
This expert is Dr. Lin, an expert in Hubei's Hundred People Program and a member of the 3551 Optical Valley Talent Program. He is also the founder of SILKPRO. After 16 years of focused research, from initial inspiration to technological breakthroughs, he brought laser lighting into the public eye. His goal was to present this unique development as a gift for the 2017 Munet Open.
**First Encounter: The Shock of Laser Light**
To others, Yang Lin achieved what seemed impossible in just one year, but his journey with laser lighting began over 16 years ago. In 2001, while studying in Germany at the Technical University of Berlin, he specialized in diode-pumped solid-state laser technology. During an experiment with Dr. Volker Gaebler, he witnessed blue light emitted from a fiber laser pumped by a red diode laser. The effect was stunning—blending blue and red light to create a beautiful pink glow that illuminated the entire lab.
That moment left a lasting impression on him. “I didn’t expect to see such a beautiful and shocking display of light,†he recalls. It was the first time he truly understood the potential of laser lighting.
**A Seed: Inspiration for Laser Lighting**
That encounter planted a seed in Yang Lin’s mind. As he gained experience working with top lighting and semiconductor laser companies, the seed began to grow. In 2004, he joined Osram in Germany as a product manager for Asian markets, gaining deep insight into the lighting industry. Later, he worked at DILAS, a global leader in high-power semiconductor lasers, where he gained valuable experience in laser display technologies like laser TV and projection.
These experiences sparked an idea: “Why can’t laser and lighting be combined?†With his expertise in both fields, he felt uniquely positioned to explore this possibility. He spent countless hours in the lab, even turning his home into a makeshift workspace.
In 2011, on his birthday, he conducted a test at home using a fiber-coupled solid-state laser. The pure green light it produced transformed the room into a dream-like forest. However, this was still far from his ultimate vision. Solid-state lasers were too large, expensive, and limited in color, making full-color laser lighting a distant dream.
**A Firm Decision: Never Giving Up on Laser Lighting**
In 2012, Yang Lin returned to Wuhan and founded SILKPRO, focusing on the development of laser medical and cosmetic equipment. By 2016, the company had grown to be among China’s top 50 high-tech enterprises. Despite this success, his passion for laser lighting never wavered.
At the same time, Nakamura Shuji, the father of the blue LED, set up a laser lighting R&D center in Shenzhen, reinforcing Yang Lin’s belief in the future of laser illumination. According to Nakamura, laser lighting would soon replace LED lighting.
Laser lighting offers unparalleled efficiency—thousands of times more efficient than LEDs. A single laser can illuminate 100 square meters with minimal power consumption. It is brighter, more compact, and safer. Though currently used only in car headlights (like those in the BMW i8), there is no true consumer laser lighting product yet.
**A Belief: Technology Holds Infinite Possibilities**
When asked why he remained so committed to laser lighting, Yang Lin said, “It’s a belief. I don’t think about applications or commercial value—I just want to bring this technology to life.†He compared it to Toshiba’s early 1.8-inch hard drive, which was once seen as obsolete but later became essential with the rise of the iPod.
“I’m not worried about whether laser lighting will be used in the future. It will find its place in many areas, lighting the world in unexpected ways.â€
**An Innovation: Creating a World-Recognized Laser Lighting Product**
Three years ago, Yang Lin envisioned a product combining laser technology with tennis. This year, after months of R&D, the team successfully developed a full-color laser trophy featuring tennis elements. Inspired by his love for tennis and the location of his company in the China Optics Valley, he wanted to showcase the power of laser technology through this unique design.
The product contains cutting-edge “black tech.†For instance, creating a single tennis line using laser technology was a major challenge. Unlike LED strips, which are limited in their lighting capabilities, laser illumination uses fiber transmission to spread light evenly across a space. The special fiber is less than 1 mm in diameter, allowing for a precise and uniform light source.
Additionally, the team solved the issue of energy loss during fiber transmission, ensuring consistent illumination over long distances. They redesigned the laser light source engine and applied fiber homogenization technology to achieve soft, even lighting.
The high-power RGB laser light source engine is the heart of the product, offering superior performance to existing laser projectors. Its compact size and high efficiency make it ideal for a wide range of applications.
With Bluetooth control via a mobile app, users can customize colors, brightness, and dynamic lighting effects. This innovative product is the first of its kind in the world and has already secured multiple patents, showcasing the advanced technical capabilities of the China Optics Valley.
**Conclusion: The Future of Laser Lighting**
Yang Lin believes that laser lighting will soon enter daily life in various forms, bringing new surprises and colors. He continues to lead SILKPRO with a focus on innovation and excellence, driven by the spirit of “daring to be first and pursuing perfection.â€
As he puts it, “Doing what others won’t do is the key to success.†This mindset has led to breakthroughs and continuous progress in the field of laser technology.
