This invention relates to the use ahyipiel crude handpiece, more specifically, the outer shape of the irradiation device ahyipiel the body portion constituting a Consists in the body portion, a polygonal pillar shape that a circle or lamp emits light having a predetermined range of wavelength bands Doedoe configuration coupled to the body portion and is spaced apart from the lamp and, as a form surrounding the lamp in the longitudinal direction, when the vertical cross-section in the longitudinal direction with a plurality of surfaces has been opened, the incoming direction of the light emitted from the lamp reflector that condenses into And is provided in the body portion and in that it comprises at least one of the cooling module comprising a coolant line is characterized in that on the configuration. According to the inquiry. Ahyipiel handpiece comprising a reflector having a plurality of surfaces that are proposed in the present invention, by forming the longitudinal vertical section of the reflector in a shape having a plurality of curved surfaces, the developer in which the columns are concentrated in one place by dispersing the heat energy can improve. Further, according to the present invention, comprising a cooling module including a main body portion and having at least one water line and the water filter, the cooling water line (DI water) and the inside of the aperture to be circular, the inlet of the cooling water and the outlet is formed by including the flow path passing through the upper side of the reflector as a pipe connected to the water filter in a zigzag form, preventing water passage blockage caused by the scale, and an effective cooling device is possible.본 발명은 아이피엘 조사용 핸드 피스에 관한 것으로서, 보다 구체적으로는 상기 아이피엘 조사 장치의 외형을 구성하는 본체부 상기 본체부 내부에 구성되고, 미리 정해진 범위의 파장 대역을 갖는 빛을 방출하는 원 또는 다각 기둥 형태의 램프 상기 본체부와 결합되고 상기 램프와는 이격되어 구성되되, 상기 램프를 길이방향으로 감싸는 형태로서, 길이방향의 수직단면이 복수 개의 곡면을 가지고 하면은 개방되었으며, 상기 램프에서 방출된 빛을 입사방향으로 집광하는 리플렉터 및 상기 본체부에 구비되고 적어도 하나 이상의 냉각수 라인을
