Since the parameter of pulsed light generating means 22 depends on the skin type of wanted nti-freckle, wherein 1 inside of shell is close Light-emitting window 10 is additionally provided with a skin type detection device 15, and skin type detection device 15 receives the light from skin reflex and production The corresponding Lab value of the raw colour of skin, then by Lab value be converted into signal pass to coupled with skin type detection device 15 be located at control Skin detection signal receiving end in device 20, skin detection signal receiving end is according to the signal and preset condition ratio passed over Compared with determining the type of skin, the decision of skin type is divided into six classes, contingency table according to Fitzpatrick skin classification system Standard is as follows:

Type I	Shallow white skin, golden hair/red hair	Always tan severely, it will not be tanned
			Type II	Pale skin	It is easy to tan severely
Type-iii	Dark white skin	Sometimes it tans severely, it is sometimes tanned
			Type IV	Light brown skin	It is easy to tanned, seldom sunburn
Type V	Medium brown skin	Furvous is shone into, is seldom tanned severely
			Type VI	Dark brown skin	Furvous is shone into, is never tanned severely

Based on the classification results, controller 20 enables pulsed light generating means 22 generate corresponding luminous energy by photocontrol end 4 The train of pulse of metric density:
