The support frame 19 is formed by connecting two plates facing each other, the two The slider 20 is positioned to be reciprocated in the longitudinal direction of the gap between the plate members of the plate 20. The lower edge of the support frame 19 has three lamps 30 and 30 'along the edge thereof. 30 ") rotatably hinged Rotating shaft mounting holes 191a, 191a 'and 191a "into which one lamp rotation shaft 191, 191' and 191" are inserted are arranged in a row. When the support frame 19 is placed in the radial direction of the case 10 and installed inside the case 10, the lamp rotation axes 191, 191 ′ and 191 ″ are parallel to the tangential direction of the circumference of the case 10. In addition, a spring connection portion 192 having one end of a spring 43 for applying an elastic force to the slider 20 is provided at the upper side toward the center end portion 195 of the support frame 19. An inner stopper 193 and an outer stopper for engaging the engaging portion 23 provided on the slider 20 between the central end 195 and the outer end 196 so as to limit the reciprocating range of the slider 20. 194 is provided apart from each other in the longitudinal direction of the support frame 19.

The lamps 30, 30 ′, 30 ″ are connected to the support frame 19 by being arranged in a row in the length direction of the support frame 19 which is installed to extend in the radial direction of the case 10. As described above, the support frame 19 is provided with three lamp rotation shafts 191, 191 ′, 191 ″. Meanwhile, each of the three lamps 30, 30 ′, 30 ″ is provided with a rotation shaft hole 19 b for connecting the lamp rotation shafts 191, 191 ′, 191 ″. The lamps 30, 30 ′ and 30 ″ are respectively inserted into the lamp shafts 191, 191 ′ and 191 ″ in the rotation shaft holes 19 b such that the light emitting portions irradiated with the light are directed downward. , 191 ") are rotatably connected thereto. Thus, the lamps 30, 30 'and 30" are parallel to the radial direction of the case 10 about the lamp rotation axes 191,191' and 191 ". Rotation is possible on a vertical surface (a plane orthogonal to the lamp rotation axis). As described above, the lamps 30, 30 ′, 30 ″ rotatably connected to the support frame 19 may include the slider 20. It is configured to be rotated side to side by the reciprocating movement of. To this end, the slider 20 installed in the support frame 19 to reciprocate in the radial direction (H direction of the drawing) of the case 10 corresponds to each of the ramp rotation shafts 191, 191 ′, 191 ″, and Lamp link shafts 21, 21 ′, 21 ″ parallel to lamp rotation shafts 191, 191 ′, 191 ″ are provided on the lamp rotation shafts 191, 191 ′, 191 ″, and the lamps 30, 30 ′, 30 ″. ) Is formed with a link shaft hole 21b for inserting the lamp link shafts 21, 21 ', 21 ". Each of the lamps 30, 30 ′, 30 ″ has a lamp link shaft 21, 21 ′, 21 ″ inserted into the link shaft hole 21 b so that the lamp links are parallel with the lamp rotation shafts 191, 191 ′, 191 ″. It is connected to the slider 20 to be rotatable relative to the slider 20 about an axis 21, 21 ′, 21 ″. The present invention is to rotate the lamp (30, 30 ', 30 ") by the reciprocating movement of the slider 20 as a whole to adjust the treatment site distance, that is, the focusing distance as described above, and at the same time the head (1) The lamps 30, 30 so that relative rotation occurs between lamps 30, 30 ′, 30 ″ arranged at different distances from the center of the case 10 so that the light is condensed at a new light collecting position with a different light collecting distance from the ', 30') are each configured to rotate with different rotation angles α, α ', and α ″. To this end, the lamps 30, 30, 30 ′ are supported by lamp rotation shafts 191, 191 ′ and 191 ″ provided in the support bracket 19 and parallel to the lamp rotation shafts 191, 191 ′ and 191 ″ thereof. (21, 21 ', 21 ") is connected to the slider 20 so as to be relatively rotatable with respect to the slider 20, and the lamps 30, 30', 30" are attached to the case 10 The distance between the lamp rotation axis 191, 191 ', 191 "and the lamp link shafts 21, 21', 21" is closer, and the light of the lamps 30, 30 ', 30 " The center line (which is connected to gather on the lower center extension line C of the case) is a conceptual diagram conceptually showing the operation of the slider 20 and the lamps 30, 30 ', 30 "as described above. Referring to FIG. 9, the light converging lines include the optical center lines B1, B1 ′, B1 ″ (B2, B2 ′, B2 ″) of the lamps 30, 30 ′, 30 ″, and an extension line below the center of the case 10. C) are gathered on the drawing. The example made at light positions F1 and F2 is shown .. As can be seen in the figure, the lamps 30, 30 ', 30 "are rotated to change the condensing position from F1 to F2 (or F2 to F1). Rotate the optical centerline from B1, B1 ', B1 "to B2, B2', B2". However, as above, rotate the optical centerline from B1, B1 ', B1 "to B2, B2', B2". In order to reciprocate the slider 20, the lamps 30 and 30'30 "must be rotated at different rotation angles α, α ', and α". That is, the case 10 can be rotated by the reciprocating movement of the slider 20. The rotation angle α 'of the lamp 30' positioned in the middle is larger than the rotation angle α of the lamp 30 closest to the center of the center, and the rotation angle α of the lamp 30 'located in the middle is larger. The rotation of the lamps 30, 30 ', 30 "should be made larger than the change of the rotation angle α" of the lamp 30 "located at the outermost side. 30 ") moves horizontally It is rotated at the same time by varying the rotation angle (α, α ', α ") by one slider 20. That is, the lamps 30, 30 ′, 30 ″ are rotated at different rotation angles α, α ′, α ″, and the slider 30 for rotation of the lamps 30, 30 ′, 30 ″. ), And the moving distances S, S ', and S "of the lamp link shafts 21, 21', and 21" connected thereto are equal. To this end, the present invention is connected to the lamp rotation shafts 191,191 'and 191 ". The lamps 30, 30 ′, 30 ″ rotated about the lamp rotation axes 191, 191 ′, 191 ″ are moved away from the center of the case 10, and the lamp links 191, 191 ′, 191 ″ and the lamp links. The lamps 30, 30 ′, 30 ″ are connected to the slider 20 such that the distances L, L ′, L ″ between the axes 21, 21 ′, 21 ″ are closer to each other.

Meanwhile, as described above, the lamps 30, 30 ′, 30 ″ are rotatably connected about the lamp rotation axes 191, 191 ′, 191 ″, and the lamp link shafts 21, 21 ′, 21 ″ are connected to the slider 20. In the mechanical structure connected to), the slider 20 is theoretically rotated as well as linearly moved. Particularly, in a structure in which three or more lamps 30, 30 ', 30 "are connected as shown in the drawing, the slider ( 20) is deadlocked and the movement itself is impossible. However, the drawings are intended to conceptually describe the present invention, and in practice, the positions of the condensing positions F1 and F2 are far from the head 1 so that the rotation angles α of the lamps 30, 30 ', 30 " , α ′, α ″) is so small that rotational movement hardly occurs in the slider 20, and the slider 20 may be considered to perform only linear movement. In addition, when the lamps 30, 30 ′, 30 ″ are loosely connected through the lamp rotation shafts 191, 191 ′, 191 ″ and the lamp link shafts 21, 21 ′, 21 ″ (loosely connected to the possible lamp link shafts). Even if three or more lamps are connected, the problem caused by the deadlock of the slider 20 does not occur.

Various lamps may be used as the lamps 30, 30 ′, and 30 ″ as described above, but by using a lamp made of an LED element, power consumption may be reduced and control may be facilitated.
