Thermal solution for phototherapy device

Introduction of phototherapy device:

Phototherapy instrument is also called ultraviolet phototherapy instrument, Fuguang Puzhi phototherapy instrument, rhinitis phototherapy instrument, etc. Phototherapy is a physical therapy technique that uses ultraviolet rays to irradiate the human body to prevent and treat diseases.
In modern photomedicine, the light therapy instruments used include red light therapy instruments, infrared therapy instruments, ultraviolet therapy instruments and other light therapy instruments. Most of the light sources of these light therapy instruments, whether they are point light sources or planar light sources, are fixed on a hard substrate, and the emitting light sources cannot be bent. Due to the straight-line propagation characteristics of light, when the light emitted by the phototherapy instrument irradiates the body skin, the light power density received by the skin at different angles is different, especially when the skin angle changes greatly in the treatment area of ​​the lesion, such as the neck, On the skin of the face and elbow, the irradiated light spots cannot vertically irradiate the skin at different angles at the same time, resulting in differences in the optical power density obtained by the skin in the lesion area (ie, the location of the lesion, such as the diseased area of ​​the head, the diseased area of ​​the foot, etc.). great, affect the treatment effect. Clinically, it has been shown that light of a specific wavelength irradiates the lesion area and has a significant effect on the treatment of tissue damage and inflammation, degenerative changes of bone and joints, pain, some skin diseases and body surface photodynamic therapy.

Phototherapy device structure composition:

A layered structure for a flexible wearable light therapy instrument comprises: an outer surface layer, the outer surface of which is configured as an appearance surface of the layered structure; a circuit layer, a flexible circuit board integrated with a control module is arranged in the circuit layer; a light source layer, the light source layer is provided with uniformly distributed light sources controlled by the control module; the uniform light material layer; layer and exit from the light exit surface.

Glue requirements for phototherapy apparatus:

  1. High bonding strength to the chassis frame;
  2. Excellent heat dissipation for heating components;
  3. Environmental protection, non-toxic, with routine testing certification and qualifications;
  4. Moisture-proof, anti-static, dust-proof, mildew-proof, salt-fog resistance, etc. for circuit boards.

Glue scheme for phototherapy apparatus:

Glue position for phototherapy deviceGlue function categoryFeatures of glue
