PURPOSE: A distance control device for a streetlight lens is provided to control the distance between an LED lamp and a lens by drawing out a moving unit from a screw hole of a coupling plate. CONSTITUTION: A plurality of screw holes(22a) are formed on a coupling plate(22) of a coupling unit(19). A moving unit is screwed on a screw hole. A lens(20) is mounted on the moving unit. A lower center of the lens receives an LED lamp(14) of an LED lamp unit(15). A pressure fixing unit is combined with the moving unit to expose the lens. A fixing unit includes a rotation pin. One end of the rotation pin is rotatably fixed on the coupling plate.
