The present invention relates to a hand piece for intensive pulse light irradiation. The hand piece for intensive pulse light irradiation comprises: a main body part which forms an appearance of the hand piece for intensive pulse light irradiation; a lamp in the shape of a cylinder or a polyprism which is arranged inside the main body part and irradiates light having a predetermined rage of the wave length; and a reflector which is joined to the main body part, is separated from the lamp, is in the shape covering the lamp in the lengthwise direction, has a lengthwise cross section having a plurality of curved surfaces, has an open lower side, and collects light irradiated from the lamp in the incident direction; and a cooling module which is arranged in the main body part and includes at least of one cooling line. According to the present invention, the hand piece for intensive pulse light irradiation with a reflector having a plurality of curved surfaces includes the reflector of which the vertical cross section in the lengthwise direction of the reflector is formed to have a plurality of the curved surfaces. Therefore, heat energy is dispersed; and thus a phenomenon that heat is focused on one spot can be reduced. In addition, according to the present invention, the hand piece for intensive pulse light irradiation includes the cooling module which is arranged in the main body part and includes at least one cooling water line and a water filter. The cooling water line has a hollow inner side for circulation of the cooling water (DI water) and includes a flow channel which is in the shape of a pipe having an inlet and outlet joined to the water filter and passes above the reflector in a zigzag manner. Therefore, clogging in a water channel, caused by impurities in water, can be prevented; and the apparatus can be effectively cooled. |
