Abstract: A control method for a light therapy device, including steps of: set a light dose range (1-4J/cm2) required by an illuminated portion under a skin surface; calculate an appropriate intensity range outputted by a light source based on the set light dose, an illuminated time, and a proportion of light beam shape variation between the light source and the skin surface; build a corresponding relation between the appropriate intensity range and an ideal illumination range for the skin surface; measure an illumination of the skin surface, and monitor an output light intensity of the light source based on the illumination, ensuring that a light intensity outputted by the light source is a set ideal light intensity whereby, a light dose transmitted from the light therapy device to the illuminated portion could be kept in the set light dose by simply controlling the illumination to be within the set illumination range.

Abstract: Disclosures of the present invention describe a phototherapy device mainly comprises a phototherapeutic host and a patch module having a connection base, wherein the patch module can be assembled with the phototherapeutic host by letting the connection base be connected with the base through an interlocking mechanism, a rotary locking mechanism or a magnetic lock mechanism. In addition, the phototherapeutic host can be attached to and detached from the patch module. Briefly speaking, this phototherapy device has advantages of simple structure, small volume, being portable, being easy to be operated, and having patch units that are replaceable. In addition, the phototherapeutic host is designed to have a modular structure comprising a base, a PCB, a lighting unit, and a cover, such that the phototherapeutic host can be manufactured and/or used individually.
