Abstract

The present invention relates to a light treatment apparatus and a method of controlling the same, and provides to a light treatment apparatus and a method of controlling the same, including: a treatment light irradiating unit for irradiating a treatment region with treatment light a plurality of times while moving on the treatment region; a sensing unit for detecting movement information of the treatment light irradiating unit; and a control unit for controlling an irradiation pattern of the treatment light based on the detected movement information such that an irradiation area of the treatment light to be irradiated from the treatment light irradiating unit overlaps at least in part with an irradiation area of the treatment light which is previously irradiated.

What is claimed is: 
     
         1 . A light treatment apparatus comprising:
 a handpiece including a treatment light irradiating unit for irradiating a treatment region with a plurality of treatment lights, the plurality of treatment lights including first and second treatment lights, the second treatment light being irradiated subsequently to the first treatment light;   a sensing unit for detecting movement information of the handpiece; and   a controller for controlling an irradiation pattern of the plurality of treatment lights based on the detected movement information such that a first irradiation area of the first treatment light is located at a distance from a second irradiation area of the second treatment light,   wherein the controller controls the irradiation pattern by irradiating the treatment region with the first treatment light and the second treatment light while the handpiece continuously moves over the treatment region such that the first and second irradiation areas are apart from each other at a predetermined distance.   
     
     
         2 . The light treatment apparatus of  claim 1 , wherein the controller adjusts an irradiation time of each of the plurality of treatment lights based on the movement information detected by the sensing unit. 
     
     
         3 . The light treatment apparatus of  claim 1 , wherein the controller controls the plurality of treatment lights to be sequentially irradiated, and controls the second treatment light to be irradiated when detecting that the handpiece including the treatment light irradiating unit has moved the predetermined distance after irradiation of the first treatment light. 
     
     
         4 . The light treatment apparatus of  claim 1 , wherein the controller controls an irradiation time of each of the plurality of treatment lights to be faster than a reference period if a moving speed of the handpiece including the treatment light irradiating unit is faster than a predetermined reference moving speed, and controls the irradiation time to be later than the reference period if the moving speed of the handpiece is slower than the predetermined reference moving speed. 
     
     
         5 . The light treatment apparatus of  claim 1 , wherein the irradiation pattern is related to an irradiation timing of the treatment light, or an irradiation interval between the treatment lights. 
     
     
         6 . The light treatment apparatus of  claim 1 , further comprising: a setting unit for setting the predetermined distance. 
     
     
         7 . The light treatment apparatus of  claim 1 , wherein the controller stops irradiating the treatment region when the sensing unit detects that a moving direction of the handpiece is reversely changed. 
     
     
         8 . A light treatment apparatus comprising:
 a handpiece including a treatment light irradiating unit for irradiating a treatment region with a plurality of treatment lights, the plurality of treatment lights including first and second treatment lights, the second treatment light being irradiated subsequently to the first treatment light;   a sensing unit for detecting movement information of the handpiece; and   a controller for controlling an irradiation pattern of the plurality of treatment lights based on the detected movement information such that a first irradiation area of the first treatment light is located at a distance from a second irradiation area of the second treatment light,   wherein the controller controls the irradiation pattern by irradiating the treatment region with the first treatment light and the second treatment light while the handpiece continuously moves over the treatment region such that the first and second irradiation areas are apart from each other at a predetermined distance.   
     
     
         9 . A method of controlling a light treatment apparatus comprising the steps of:
 irradiating a treatment region with a plurality of treatment lights by operating a treatment light irradiating unit included in a handpiece, the plurality of treatment lights including first and second treatment lights, the second treatment light being irradiated subsequently to the first treatment light;   detecting movement information of the handpiece; and   controlling an irradiation pattern of the plurality of treatment lights based on the detected movement information such that a first irradiation area of the first treatment light is located at a distance from a second irradiation area of the second treatment light,   wherein the treatment region is irradiated with the first treatment light and the second treatment light while the handpiece continuously moves over the treatment region such that the first and second irradiation areas are apart from each other at a predetermined distance.   
     
     
         10 . The method of  claim 9 , wherein the second treatment light is irradiated when it is detected that the handpiece has moved by a reference distance after irradiation of the first treatment light. 
     
     
         11 . The method of  claim 9 , further comprising:
 detecting a distance that the handpiece moves from a position irradiated with the second treatment light; and   irradiating a third treatment light based on the movement distance after the irradiation of the second treatment light such that a third irradiation area of the third treatment light is located at the predetermined distance from the second irradiation area of the second treatment light.
