The present invention relates to a movable lamp-type collimator configured to simultaneously move a lamp unit, which emits light, and a condensing lens, which condenses the light, such that the lamp unit and the condensing lens clearly display a cross point at a specific part of a human body, and the lamp unit and the condensing lens return to original positions after displaying the cross point, thereby enabling accurate irradiation of X-rays from X-ray equipment to a specific part of the human body (inflicted part), which is the X-ray imaging position, without interfering with the X-rays. To this end, a collimator according to the present invention comprises: a body case having an inlet and an outlet, through which X-rays enter and exit, and a transmission window provided with a cross point a lamp unit installed inside the body case to emit light for displaying a cross point in the X-ray imaging position a condensing lens coupled to the front side of the lamp unit to condense light a PCB substrate coupled to the rear of the lamp unit a heat radiation plate, to which the PCB substrate is coupled to radiate heat to the outside a driving means for causing the heat radiation plate, to which the lamp unit is coupled, to make reciprocating movements in left and right directions inside the body case and a shielding unit movably installed inside the body case and provided with a plurality of shielding plates to adjust the irradiation direction and radiation range of X-rays and light.La présente invention concerne un collimateur de type à lampe mobile configuré pour déplacer simultanément une unité de lampe, qui émet de la lumière, et une lentille condensatrice, qui condense la lumière, de sorte que lunité de lampe et la lentille condensatrice affichent clairement un point de croisement au niveau dune partie spécifique dun corps humain, et lunité de lampe et la lentille condensatrice retournent à leur position originale après laffichage du point de croisement, de manière à
