• Two innovative technologies ensure high optical density.
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, high optical power, rapid efficacy, and no significant thermal side effects.
Automatic constant-temperature system
The red-and-blue light 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 red-and-blue light therapy device boasts the highest light power density in the industry worldwide, rapidly stimulating cellular photobiological and biochemical responses and 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 red‑blue light therapy device can rapidly and effectively treat inflammatory acne. Its mechanism involves blue light, when applied to affected skin lesions, stimulating porphyrins within cutaneous enzymes to release large amounts of singlet oxygen, thereby exerting antibacterial and anti‑inflammatory effects. In addition, 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 red-and-blue light therapy device induces photochemical effects on the skin and underlying 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 red–blue light therapy device, the photodynamic energy resonates with the absorption spectrum of mitochondria in human tissues, triggering a cascade of photochemical reactions and photostimulatory effects. The 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 (GF), fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), and others, 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 red-and-blue light therapy device delivers high energy with low heat, targeting the specific absorption wavelength of cytochrome c oxidase at 630 nm. It does not cause localized heating, thereby promoting microcirculation of body fluids and maintaining a moist wound environment. Additionally, it can penetrate granulation tissue, scabs, and intact skin by 3–5 mm, achieving deep‑tissue therapeutic effects.
