Objective:Photothermal therapy is a kind of physical treatment major of light and heat. Photochemical and thermal effects produced by specific wavelengths of light to treat human tissue irradiated skin tissue disease, and has a therapeutic effect significant features. For real-time monitoring, control light and heat treatment temperature during irradiation site organization, this paper presents the design of a temperature-controlled LED light heating therapy system based STC12C5A60S2.Methods: Hardware of System consists of an LED array light source driving section, infrared temperature measurement part, and human-computer interaction part of the microprocessor portion. According to the temperature of human tissue control requirements, the LED output optical power density is adjusted using the traditional PID algorithm.Results: The isolated tissue sample is selected in the photothermal therapy experiment. The experimental results show that the settling time and peak overshoot of the temperature control system are low. and the steady- state error is±0.5℃.Conclusion: The design of treatment system of LED based on PID can meet that the requirement of temperature control in the photothennal therapy.
