Product Features
Biological semiconductor light source
Original imported medical high‑power semiconductor integrated module from the U.S. company SET, featuring uniform optical density, a pure light source, and an output power exceeding 2,000 mW—delivering rapid results with no significant thermal side effects.
Automatic constant-temperature system
The semiconductor spectral therapy device can maintain the temperature below 26°C, ensuring exceptionally long operating times with no attenuation of irradiation energy, thereby achieving superior temperature-control efficiency and fully safeguarding the equipment’s high performance and stability.
High optical power density and stable wavelength
The semiconductor spectral therapy device delivers high optical power density and stable wavelengths, rapidly stimulating cellular photobiological and biochemical responses, thereby significantly enhancing clinical treatment outcomes.
Large treatment area
It provides a sufficient effective treatment area, fully meeting the clinical needs for managing large‑area, complex, and hard‑to‑heal wounds.
Significant clinical therapeutic effect
It can accelerate the healing of wounds and ulcers, thereby shortening the duration of clinical treatment. It demonstrates significant therapeutic efficacy for refractory wounds that respond poorly to or fail to respond to conventional clinical therapies.
Technical Principle
Bactericidal and acne-fighting
The semiconductor spectral therapy device can rapidly and effectively treat inflammatory acne. Its mechanism involves blue light, which, when applied to affected skin lesions, stimulates the release of large amounts of singlet oxygen from porphyrins within cutaneous enzymes, thereby exerting antibacterial and anti-inflammatory effects. Additionally, blue light exerts a bio‑regulatory effect, moderately inhibiting sebum secretion, reducing the severity of skin lesions, suppressing recurrent outbreaks, and promoting tissue repair. Long-term clinical observations have demonstrated that blue light is a highly pure, deeply penetrating wavelength that does not harm healthy skin, has no adverse side effects, and represents the optimal spectral range for bactericidal action and acne clearance.
A spectral “analgesic”—significantly alleviates pain.
The semiconductor spectral therapy device induces photochemical effects on the skin and deep tissues, accelerating the resolution of inflammation and reducing serotonin synthesis. It also effectively suppresses neural irritation caused by inflammatory lesions or psychological factors, providing relief from both acute and chronic pain.
Promote moist wound healing
● During treatment with a semiconductor spectral therapy device, photodynamic effects resonate with the absorption spectra of mitochondria in human tissues, triggering a series of photochemical reactions and photostimulatory effects. Photodynamic energy is extensively absorbed by cellular mitochondria, activating cytochrome c oxidase (Cyt) within the mitochondria and initiating highly efficient enzymatic reactions that enhance cellular metabolism.
● Red light can also enhance the production of reactive oxygen species (ROS). ROS act as signaling molecules, promoting the expression of cytokines (such as growth factors, fibroblast growth factor, vascular endothelial growth factor, etc.), thereby accelerating granulation tissue formation and wound healing.
● When tissue is injured or undergoes pathological changes, irradiation with red light can dissociate nitric oxide from oxidases, thereby enhancing the binding of oxygen to cytochrome c oxidase (Cyt), improving cellular energy metabolism in chronic wounds, and accelerating wound healing.
● The semiconductor spectral therapy device delivers high energy with minimal heat, focusing on the cytochrome c oxidase–specific absorption wavelength of 630 nm. It avoids localized thermal heating, promotes microcirculation of body fluids, maintains a moist wound environment, and can penetrate granulation tissue, scabs, and normal skin by 3–5 mm, achieving deep‑tissue therapeutic effects.
