The present invention relates to a handling-improved waterproof socket-type halogen lamp for a pen, wherein the halogen lamp (200) comprises a socket unit (100) and a tubular halogen lamp (200) having a lamp terminal at both ends supported by and connected to a contact point (30) by the two socket units (100). The socket unit (100) comprises: a fixture (10) for forming a hollow unit having a wire (40), a circular insulator (50) and a spring (60) installed therein a side plate (20) for finishing an outer side of the fixture (10) a contact point (30) located inside the circular insulator (50) and coupled to the inner end of the wire (40), thereby electrically coming into contact with one electrode of the tubular halogen lamp (200) the wire (40) for supplying power to the contact point (30) through the hollow unit (12) after passing the side plate (20) the circular insulator (50) for insulating the contact point (30) and the fixture (10) after being inserted into and contained in an inner side of the hollow unit (12) the spring fixture (10) installed in the hollow unit (12), and having an outer side supported by the side plate (20) and having an inner side supporting an outer side of the circular insulator (50), thereby providing force of restoration while supporting one electrode of the tubular halogen lamp (200) through the contact point (30) and an inner side waterproof packing (80) in a closed curve shape for preventing moisture or dust from penetrating into the inner end of the fixture (10) and for having a terminal passage groove (85), through which a lamp terminal housing (210) passes, formed thereon.COPYRIGHT KIPO 2016축사용 할로겐 램프에 있어서, 전선(40)과 환형 애자(50)와 스프링(60)이 내장되는 중공부를 형성하는 고정체(10)와, 상기 고정체(10)의 외측을 마감하는 측면판(20)과, 환형 애자(50)의 내측에 위치하고, 상기 전선(40)의 내측단에 결합되어, 상기 직관형 할로겐 램프(200)의 일극에 전기적으로 접촉되는 접점(30)과, 상기 측면판(20)을 통과한 후 상기 중공부(12)를 거쳐서 상기 접점(30)에 전원을 공급하는 전선(40)과, 상기 중공부(12)의 내측에 삽입 안치된 후 상기 접점(30)과 상기 고정체(10)를 절연시키는 환형 애자(50)와, 상기 중공부(12)에 내장되고 외측은 상기 측면판(20)에
