Low-powered, low-level light therapy with light-emitting diodes (LED) at some specific wavelengths has attracted attention in wound healing indications to accelerate wound healing and ameliorate pain for enhancing quality of life. For example, based on the development in the NASA Space Medicine Laboratory, the wavelength of 830 nm offers deep penetration into living biological tissue, including bone. A growing body of clinical evidence is showing the healing outcomes with effective results. There are also startups aiming to provide new healthcare devices that use clinically useful irradiance.
Light Photons Co., as a Taiwan-based startup, develops a range of healthcare products based on AVS (Audio-visual Stimulation) and LLLT (Low-Level Light Therapy) technologies to seek the potential of skin conditions, alleviating joint pain, or improving relaxation function. These solutions are becoming a fast-growing technology to treat many situations that require healing stimulation, relief of pain or inflammation, and restoration of function, leveraging photons at a non-thermal irradiance to alter biological activities. Yen Lin (known as Wilson Lin) founded Light Photons in 2024. In this interview, he talked about his product ideas, which initially came from his previous work in the semiconductor and personal computer (PC) industries. His Lab background in high-frequency serial bus and optical played a crucial role in identifying and developing the company's core technology. With years of experience as a PC system architect and gaining valuable skills in Firmware / Software design, system engineering, and technical problem-solving, the primary challenges came from understanding and integrating knowledge from various fields, such as optics, electronics, and biology. Looking at his background, he started developing Firmware. He began the journey of deepening knowledge of high-speed serial bus communication protocols, including PCIe, USB interfacing technologies, and more hardware-software integration after joining AMD, HPE, and ODM companies. He explained his work scope at HPE LAB since 2010 for research, development, and verification of related digital signaling systems by incorporating high-frequency bands protocols and other related fiber optic technology in laboratory work.

The Brain Computer Interface capabilities in indirect effect
Through many years of R&D work, he enrolled in an extensive practical R&D management academic training program (EMRD) at the National Taiwan University of Science and Technology (NTUST). He joined the study at Taiwan's National Tsing Hua University (NTHU) for introductory neuroscience courses. In these study courses and extended studies, he was motivated by his desire to find that the treatment's capabilities and the human body's effectiveness can make biological data networks, just like a PC system. During these courses, multiple continuous international studies have provided a more reliable possibility of the human body's cognitive pathway to transmit messages through a smaller and closed network, which could be analyzed through different methods. He started to develop and make prototyping LED-based electronics devices, focusing on light-related solutions that harness light's benefits to impact skin and bone health positively. So, Lin's basic product concept explores human body networks and communication behavior with light wavelengths and wave frequencies influence. Light Photons' product strategy is focused on the healthcare market for rehabilitation and relaxation. The company is targeting the initial market expansion to the Southeast Asian and Middle Eastern markets.
Improve cognitive function
Light therapy has been used to treat some mental and sleep disorders for years. Lin set his research topic to identify the capability of these technologies through his collaborative research projects. Based on the conference paper in 2024 titled ??Adequate LED-based light with EEG alpha wave discussed in the Relaxation?? in the IEEE 6th Eurasia Conference on Biomedical Engineering, Healthcare and Sustainability Conference. In this paper, Lin and the team in this project conducted a research study that involved a group of 30 participants aged between 20 and 40 years old. Measuring alpha brain wave percentage in individuals and referencing the General Anxiety Disorder-7(GAD-7) check routine during the experiment. This design can reveal patterns associated with comparison. In this study, each individual will be exposed to the light generated by Lin??s LED-based device at a distance between 20 and 60 centimeters for a time duration of 5 to 20 minutes. A six-channel dipole record was collected based on an electroencephalography (EEG) alpha wave frequency review. With these scientific data gathering, the paper shows a table to measure and analyze the effectiveness of light wavelengths. Meanwhile, after this physical light exposure and measurement procedures, each participant will be investigated following the Anxiety Disorder Diagnostic Table GAD-7 to answer a brief self-report questionnaire to assess the emotional ratings and indicate the difference after the light treatment. This study concludes the effectiveness of blue-green and orange-red wavelengths in dark environments, giving the Low-Level Light devices positive results. In this study, 95% of participants experienced positive emotional states, which is a strong understanding of their product design concept. After months of implementing design improvements, the company recently announced its new product series, including AVS (Audio-visual Stimulation) equipment and LLLT (Low-Level Light Therapy) devices. Both products leverage LED-based technology to generate low-level lights based on visual light wavelengths. Lin gives a simple and straightforward demonstration with his smart watch to record the different scores to indicate the effectiveness before and after using LED-based and AVS-based devices. This demo shows the product's capability proposition and possibility. There are several enquiries during Arab Health 2025 in Dubai (United Arab Emirates) to introduce devices as effective self-care devices.

Continuous study of the light and wave effects on skin and bone remodeling
The skin is naturally exposed to light more than any other organ, with visual and non-visual light wavelengths. The company referenced the light wavelength range for skin effectiveness. It still responds well to red and near-infrared wavelengths as the device's base light source. The company is exploring red light electronic devices as a tool to support skin health. To expand its product offerings, the company developed a new product lineup, including the Anti series for visual light wavelengths. Lin provides different mindsets for rehabilitation considerations compared with similar products in the healthcare market. According to understanding the rehabilitation phases, each phase contains different conditions for mixed light wavelengths and waves in frequency. The first product is an Anti-Oxid device, which can be used during the Cell inflammatory phase. The Activation AVS device will consider situations during the Cell proliferation phase. The Strong AVS device will perform the Cell or bone remodeling phases in the third phase. For healthcare considerations, there are always some primary processes to achieve the market's goal. Production is only part of this process. These ongoing development projects show the design capability of Lin??s engineering teams. Nowadays, Light Photons Co. provides Low-Level Light electronic devices for rehabilitation and relaxation purposes. The LED-based series devices consume under 1 watt of power, just like night lamp devices, but provide various functionality with safety and sustainable features for the rehabilitation market. The rehabilitation equipment market encompasses a wide range of devices and tools designed to help individuals recover, improve, or maintain their physical capabilities following injury, surgery, illness, or the onset of chronic conditions. For this high-growth market, the company's business model involves manufacturing and design of products under the OEM and ODM frameworks. They are also open to collaborating on research projects and will likely explore new designs and product concepts.
