D, control circuit obtain target adjustment amount number according to the optical power density data and current light intensity regulation data According to, and voluntarily adjust according to target adjustment amount data the size of current or ultraviolet source of power supply output ultraviolet source Irradiation time length;Electric current and ultraviolet source of the target adjustment amount data including power supply output ultraviolet source Irradiation time.
Specifically, light intensity dosage set in advance is the ultraviolet light treatment that should be received according to illuminated person in stepb Dosage is come what is set, and after input intensity of illumination and light application time, the light intensity calibration module in control circuit obtains light intensity dose value. Calibration curve set in advance is the functional relation of light intensity magnitude and optical power density in step C, and calibration curve can be by light Strong calibration module is set to fixed function, or measure according to the different of ultraviolet source but actually the function of establishment, Actual measurement establishment function is obtained pair when the main frame of ultraviolet light therapeutic apparatus is connected different types of ultraviolet light treatment handle Should be in the calibration curve of ultraviolet light treatment handle.
With reference to Fig. 6, step S100 is the process that calibration curve function is worked out in actual measurement, light intensity calibration mould in the present embodiment Block changes the light intensity magnitude of ultraviolet source, and the optical power density under different light intensity magnitudes is measured using optical power density meter, will Measured value works out calibration curve as standard value.Then in step s 200, set in the memory cell of light intensity calibration module To light dosage and the functional relation of light intensity regulating data, when user inputs illumination dose or illumination when using ultraviolet light therapeutic apparatus Between, after intensity of illumination, light intensity calibration module be can obtain user set dosage corresponding to light intensity regulating data.In step S300 In, the ultraviolet light transducer detection ultraviolet source luminous intensity size in main frame groove is stored after the value is digitized To memory cell.In step S400, light intensity calibration module is substituted into the light intensity value of storage as a parameter in calibration curve Draw the corresponding optical power density of this light intensity value.In step S500, light intensity calibration module is according to the optical power density data With regulation data, target adjustment amount data are obtained, it is defeated that light intensity calibration module voluntarily adjusts constant-current source according to target adjustment amount data Go out size of current or ultraviolet source irradiation time length.
Further, in order to ensure the security and the validity for the treatment of of ultraviolet light therapeutic apparatus, need before treatment pair Shone thing surface temperature is detected in real time, therefore, as shown in fig. 7, also including step before step A is performed:
A0, ultraviolet light treatment handle measure the actual temperature on shone thing surface by infrared measurement of temperature module in real time, and sentence Whether the actual temperature of breaking is in predetermined treatment temperature range, when the actual temperature is less than predetermined treatment temperature range, The constant-current source of circuit control driving infrared LED lamp is controlled with maximum gear output current, and it is real-time to shone thing surface temperature Detection and feedback;Actual temperature is less than predetermined treatment temperature range, it was demonstrated that shone thing is that patient skin surface temperature is relatively low, no Beneficial to treatment, therefore by adjusting constant-current source with maximum gear output current, infrared LED lamp is set to be sent within the shortest time stronger Infrared light, patient skin is irradiated, by the surface temperature of patient skin lifting to predetermined treatment temperature range.
A1, when actual temperature be higher than predetermined treatment temperature range when, control circuit control driving infrared LED lamp constant-current source Stop output current;The actual temperature on shone thing surface is higher than predetermined treatment temperature range, it was demonstrated that shone thing is patient's skin Skin surface temperature is too high, has been unfavorable for treatment, therefore, need to stop the irradiation of infrared LED lamp, makes patient skin surface temperature certainly So reduction.Avoid temperature too high and damage is caused to patient skin.
A2, when actual temperature be in predetermined treatment temperature range when, control circuit control driving infrared LED lamp constant-current source Stop output current, perform step A.
Further, in order to strengthen the security of ultra-violet therapy apparatus, over the course for the treatment of, it is also desirable in real time to shone thing Surface temperature is detected in real time, therefore, further comprising the steps of after above-mentioned light intensity Automatic adjustment method referring to Fig. 8:
E, ultraviolet light treatment handle measure the actual temperature on shone thing surface by infrared measurement of temperature module in real time, and judge Whether actual temperature is in predetermined temperature range, when the actual temperature is in predetermined treatment temperature range, performs step A- D;
When the actual temperature is higher than predetermined treatment temperature range, control circuit control constant-current source proportionally reduces defeated Go out size of current, and to the detection in real time of shone thing surface temperature and feed back;
When the actual temperature is less than predetermined treatment temperature range, control circuit control constant-current source proportionally raises defeated Go out size of current, and to the detection in real time of shone thing surface temperature and feed back.In the process, controlled by control circuit infrared The constant-current source of LED proportionally raises output current size, and to the detection in real time of shone thing surface temperature and feeds back;Until The actual temperature on shone thing surface is in the predetermined treatment temperature range, the perseverance of control circuit control driving infrared LED lamp Stream source stops output current;And when actual temperature is higher than the predetermined treatment temperature range, control circuit control driving is ultraviolet The constant-current source of radiant and the constant-current source of control driving infrared LED lamp stop output current respectively, and produce sound or acousto-optic report Alert, to point out user or doctor, skin surface temperature is too high.
Further, with reference to Fig. 9, in the present embodiment, step S600 obtains illuminated by infrared measurement of temperature module first The surface temperature of thing.The size of later step S700 light intensity calibrations module comparison surface temperature and safe temperature, such as 41 is Celsius Degree, the size of comparison surface temperature and action threshold value, such as 38 degrees Celsius.Wherein, the surface temperature of shone thing is the reality Border temperature, the predetermined treatment temperature range is the temperature range between action threshold value and safe temperature.Final step S800 light intensity calibrations module performs corresponding regulation process according to step S700 comparative result, if surface temperature is more than safety temperature Degree, then reduce output current according to the difference of surface temperature and safe temperature according to default regulation ratio;If surface temperature is small In safe temperature and more than action threshold value, then the step S100-S500 of above-mentioned light intensity Automatic adjustment method is performed;If surface temperature Less than action threshold value, then output current is increased according to default regulation ratio according to the difference of action threshold value and surface temperature.
In step S600, the infrared measurement of temperature module on ultraviolet light treatment handle is according to total in the range of all wavelengths Radiate and constant temperature, what is obtained is the radiation temperature of object.Infrared measurement of temperature module is infrared temperature sensor in the present embodiment.
