Example Embodiment
[0038] Example one
[0039] reference figure 1 , Provides a hand-held dry eye phototherapy equipment, including a housing 1, the housing 1 is provided with a light outlet 10, inside the housing 1 near the light outlet 10 is provided with a pulse light generating device 22, the housing 1 is also provided with a controller 20 for driving the pulsed light generating device 22 and a power supply 21 for powering the controller 20 and the pulsed light generating device 22. The controller 20 includes a light control terminal 4 and a power receiving terminal 9. The light control terminal 4 contains a control circuit, the pulse light generating device 22 is coupled to the light control terminal 4 through the control circuit, and the power source 21 is coupled to the power receiving terminal 9; the pulse light generating device 22 is controlled by the light control terminal 4 to generate light A pulse train with an energy density of 1J / cm² to 25J / cm², the pulse train is composed of a plura...
Example Embodiment
[0079] Embodiment two:
[0080] Provided is a dry eye phototherapy method, which is applied to any of the handheld dry eye phototherapy equipment in the first embodiment, and specifically includes the following steps:
[0081] The intelligent detection device receives the reflected light reflected from the skin, generates a Lab value according to the light intensity and spectral distribution of the reflected light, and sends the Lab value as a skin detection signal to the skin detection signal receiving end;
[0082] After the skin detection signal receiving end receives the skin detection signal, the controller judges whether it touches the skin according to a preset value, and if it touches the skin, it classifies the skin type according to the Fitzpatrick skin classification system;
[0083] According to the classification category, the pulsed light generating device generates short pulses at intervals of 0.1ms to 50ms through the control circuit to form a pulse train suitable for t...
