[0020] Hereinafter, a rotary beacon according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0021] Figures 1 to 3 illustrate a rotary beacon (1) according to a first embodiment of the present invention.

[0022] A rotary light fixture (1) according to a first embodiment of the present invention is not specifically illustrated, but comprises a lower body (10), a rotation module (not illustrated) that is rotated by a motor on the upper side of the lower body (10), a light-emitting module (100) that is mounted on the upper side of the rotation module and is rotatable together with the rotation module, and an upper cover (200) that covers the upper end of the light-emitting module (100).

[0023] The lower body (10) is formed with an internal space (not shown) with an open top, and a motor for rotating the rotation module, a battery or communication module, and a control unit for power supply are built into the internal space. The motor is fixedly mounted so that no movement occurs due to the structure.

[0024] A light emitting module (100) is formed of a polyhedron having a predetermined length and a hollow (102) formed on the inside, and has a lens mounting portion (101) having a plurality of lens assembly surfaces (103) formed thereon and a heat dissipation structure provided on the inside corresponding to the lens assembly surfaces (103); a plurality of light sources (121) arranged vertically at predetermined height intervals on each lens assembly surface (103); a lens module (151) mounted on the center side is positioned in front of the light source (121) so as to cover the lens assembly surface (103) around each light source (121) or to allow the light source (121) to be exposed to the outside, and a plurality of light source opening and closing plates (131) arranged vertically on one lens assembly surface (103) so as to be rotatably mounted on one side of the lens mounting portion (101) so as to intersect the lens assembly surface (103) and; A spacer plate (141) is provided, which is positioned around the light source (121) so as to face the light source opening / closing plate (131) that is rotated to cover the lens assembly surface (103), and is positioned between the light source opening / closing plate (131) and the lens assembly surface (103), and has a through hole (142) formed therethrough toward the front side.

[0025] The light source (121) is an LED lamp (light emitting diode lamp) and may include R, G, and B LED elements for emitting single-color or multi-color light.

[0026] The lens mounting portion (101) is provided with a plurality of vertical bars (105) that are extended in an upright manner upwardly and spaced apart from each other at regular intervals in the circumferential direction, a plurality of heat dissipation members (113) that are slidably connected to the vertical bars adjacent to each other in the circumferential direction on both sides so that mounting grooves (119) that are open in the outward direction are formed between the vertical bars adjacent to each other in the circumferential direction as a heat dissipation structure, and a plurality of light source mounting plates (102) that have lens assembly surfaces (103) that are received in each of the mounting grooves (119) and that are oriented toward the outward and that have light source mounting grooves (104) formed in the outward direction on one surface of the heat dissipation members (113).

[0027] The lens mounting portion (101) may be provided with six vertical bars (105), six heat dissipation members (113), and six light source mounting plates (102) so that the side surfaces are formed into six sides. Referring to FIGS. 1 and 2, the six vertical bars (105) are spaced 60° apart from each other in the circumferential direction based on the center of the hollow (102).

[0028] The vertical bar (105) and the heat dissipation member (113) are extended longer than the length formed by the plurality of light source opening / closing plates (131) and the plurality of spacer plates (141) arranged vertically.

[0029] In addition, a plurality of light source opening / closing plates (131) arranged vertically and a plurality of spacer plates (141) are mounted on the lens mounting portion (101) at regular intervals vertically and vertically relative to the lower and upper ends of the vertical bar (105) and the heat dissipation member (113).

[0030] The heat dissipation member (113) is provided with a heat dissipation plate portion (114) that extends vertically with a constant width and has a light source mounting plate (102) attached to one surface facing outward, and a number of heat dissipation ribs (118) that are formed protruding from the other surface of the heat dissipation plate portion (114).

[0031] The heat sink part (114) has a heat sink body (115) that has a constant width and is extended vertically, and a pair of coupling flanges (117) that protrude from each other on both sides of the width of the heat sink body (115).

[0032] The heat sink body (115) is formed by penetrating through a plurality of light source opening / closing plates (131) arranged vertically and a plurality of spacer plates (141) on both sides of the longitudinal direction protruding upward and downward, so that a first ventilation hole (116) connecting the space between the heat sink ribs (118) and the mounting groove (119) is formed.

[0033] A plurality of heat dissipation ribs (118) are extended in length corresponding to the vertical length of the heat dissipation plate body (115). In addition, among the plurality of heat dissipation ribs (118), the heat dissipation ribs (118) on the edge side are formed to have a shorter protruding length with respect to the heat dissipation plate body (115) than the heat dissipation ribs (118) located on the center side.

[0034] Referring to FIGS. 1 and 2, the vertical bars (105) are formed such that one side and the other side are symmetrical to each other. In addition, one side of one vertical bar (105) is formed parallel to and facing the other side of another adjacent vertical bar (105).

[0035] The vertical bar (105) is formed on one side and the other side with a first sliding coupling groove (109) that is inserted laterally and extends vertically, and a second sliding coupling groove (111) that is inserted laterally and extends vertically at a position spaced outward from the first sliding coupling groove (109), respectively.

[0036] In the first sliding joint groove (109), a joint rib (117) formed on one side in the width direction of the heat sink portion (114) or a joint rib (117) formed on the other side in the width direction of the heat sink portion (117) is slidably joined up and down.

[0037] In the second sliding joint groove (111), one side or the other side of the spacer plate (141) is slidably joined up and down.

[0038] The light source mounting plate (102) is located between the heat sink body (115) and the spacer plate (131).

[0039] That is, a pair of vertical bars (105) combined with a single heat dissipation member (113) protrude outward from both sides of the lens assembly surface of the light source mounting plate (102).

[0040] The light source mounting plate (102) can be formed as a single plate extending in a length corresponding to the length of a plurality of light source opening / closing plates (131) and a plurality of spacer plates (141) arranged vertically, and each lens assembly surface (103) has a plurality of light source mounting grooves (104) provided at regular intervals in the longitudinal direction, i.e., the vertical direction, at the center of the width in which light sources (121) are mounted.

[0041] Unlike the drawing, the light source mounting plate (102) is formed to correspond to the vertical length of one light source opening / closing plate (131) or multiple spacer plates (141), so that multiple light source mounting plates (102) can be arranged in one mounting groove (119) in the vertical direction.

[0042] The light source opening plate (131) is formed in the shape of a square plate having a width corresponding to the distance between the facing support brackets (105), and one side is mounted so as to be rotatable left and right on one of a pair of vertical bars (105) facing each other with the lens assembly surface (103) interposed therebetween.

[0043] The light source opening plate (131) has a communication hole (132) formed on the center side corresponding to or having a larger diameter than the through hole (142) of the spacer plate (141), and a first bolt through hole (134) is formed on each corner side.

[0044] Meanwhile, the spacer plate (141) has the same vertical length as the light source opening / closing plate (131), but is formed to be longer in the left and right directions, and is slid vertically and vertically connected to the second sliding connection groove (111) facing each other on both sides.

[0045] In addition, the spacer plate (141) has a bolt joint hole (144) and a second bolt penetration hole (145) formed on each corner side.

[0046] The bolt joint hole (144) is concentric with the first bolt penetration hole (134) of the light source opening / closing plate (131) that is rotated parallel to the lens assembly surface (103) and the spacer plate (141).

[0047] The spacer plate (141) can be fixed to the lens assembly surface (103) by a position fixing bolt (147) that penetrates the second bolt through hole (145) and is coupled to the lens assembly surface (103).

[0048] In addition, the position fixing bolt (147) may be extended to penetrate the spacer plate (141) toward the heat dissipation member (113) and be combined with the heat dissipation member (113).

[0049] The light source opening / closing plate (131) rotated parallel to the lens assembly surface (103) and the spacer plate (141) is limited in rotation by the opening / closing limiting bolt (146) that passes through the first bolt through hole (134) and is connected to the bolt joint hole (144).

[0050] The opening / closing limit bolt (146) can be penetrated by being screwed into the first bolt through hole (143).

[0051] When the light source opening / closing plate (131) is separated from the opening / closing limit bolt (146) in the bolt joint hole (144), the rotation restriction is released.

[0052] In addition, the light emitting module (100) further includes a plurality of support blocks (148) that are vertically slidably coupled to each other by second sliding coupling grooves (111) that face each other on both sides to support or restrain the spacer plates (141) arranged vertically and arranged downward and upward with respect to the lens assembly surface (103). Each of the plurality of support blocks (148) is formed with a second ventilation hole (149) that is connected to the first ventilation hole (116).

[0053] In addition, the light emitting module (100) is formed in a plate shape to cover the support block (148), and further includes a block cover (150) in which a plurality of branch holes (150a) formed in the shape of slits extending vertically are arranged in a continuous manner in the direction of the facing vertical bar (105).

[0054] The support block (148) has a width-wise inner side that is not connected to the second sliding coupling groove (111) and has a thickness greater than that of the restraining groove (107) and the spacer plate (141) and is supported on the lower end of the light source mounting plate (102) or supports the lower end of the light source mounting plate (102).

[0055] The lens module (151) is mounted to cover the communication hole (132) on the light source opening / closing plate (131), and includes a first lens (152), a second lens (162), and a lens support (171).

[0056] The support blocks (148) may be placed between the spacer plates (141) so that the spacer plates (141) can be placed in the light source mounting grooves (104) formed at different intervals than those shown.

[0057] The first lens (152) is formed as a smooth surface on the side corresponding to the light source (121) and as a convex aspherical surface (153) on the outer side corresponding thereto.

[0058] The second lens (162) is positioned concentrically with the first lens (152) between the first lens (152) and the light source (121), has a smooth surface on the side corresponding to the light source (121), is formed as a convex spherical surface facing the first lens (152), and has an outer diameter smaller than that of the first lens (152).

[0059] The first lens (152) and the second lens (162) may be made of transparent polycarbonate (PC: poly-carbonate) material.

[0060] The aspherical surface (153) of the first lens (152) is formed so that the curvature becomes smaller from the center to the edge, and unit curvature-forming surfaces (158) having different inclinations or curvatures can be continuously arranged along a vertical line of the center of the smooth surface of the first lens (152) from the center of the aspherical surface (153) to the edge, i.e., a line (l) connecting the centers of the first lens (152) and the second lens (162).

[0061] Specifically, the aspherical surface (153) of the first lens (152) is formed by continuously forming a plurality of annular unit aspherical focusing sections (156) whose diameters increase from the center to the edge. In addition, the unit aspherical focusing sections (156) are formed by continuously arranging a plurality of unit curvature-forming surfaces (158) along the circumferential direction.

[0062] The unit curvature forming surfaces (158) of different unit aspherical focusing parts (156) have different slopes or curvatures with respect to the line (l) connecting the centers of the first lens (152) and the second lens (162), so that the curvature of the aspherical surface (153) becomes smaller from the center to the edge.

[0063] That is, the inclination or curvature of each unit curvature-forming surface (158) of the unit aspherical focusing lens parts (156) allows light irradiated around the optical axis line passing through the center of the first lens (152) (the line (l) connecting the centers of the first lens (152) and the second lens (162)) to be directed toward the optical axis line at a desired distance in front of the first lens (152), so that light can be focused to a long distance.

[0064] As illustrated in FIG. 3, it is preferable that the inclination or curvature of each unit curvature-forming surface (158) of the unit aspherical focusing lens parts (156) be formed so that the angle of refraction of light passing through the first lens (152) gradually increases as it gets farther from the center of the aspherical surface (153). Alternatively, the inclination or curvature of each unit curvature-forming surface (158) of the unit aspherical focusing lens parts (156) may be formed so that spherical aberration becomes larger as it gets farther from the center of the aspherical surface (153).

[0065] By these unit focusing lens parts (156), the light irradiated from the light source (121) through the second lens (162) and the first lens (152) is focused toward the front central portion of the first lens (152), thereby increasing the focusing density and forming a core light having a predetermined radius up to a desired distance.

[0066] The lens support part (171) is formed in a cylindrical shape with a center hole and is connected to the light source opening / closing plate (131) so as to be positioned around the communication hole (132) of the light source opening / closing plate (131). It includes a housing (172) having a jaw (173) formed at an end facing forward for fixing a first lens (152), a first fixing ring (174) inserted into the housing (172) and in contact with the edge of the smooth surface of the first lens (152) and having a fixing jaw (175) provided at an end of the inner surface facing the light source (121) for fixing a second lens (162), and a second fixing ring (177) inserted into the housing (172) and in contact with the edge of the smooth surface of the second lens (162) and screw-connected to the inner surface of the housing (172).

[0067] Meanwhile, a heat dissipation member restraint plate (203) and a foreign matter inflow prevention device (206) are provided between the upper cover (200) and the lens mounting portion (101).

[0068] The heat dissipation member restraint plate (203) is formed in a polygonal shape to cover the upper surface of the lens mounting portion (101), and a through-hole (204) is formed in the center to facilitate heat dissipation.

[0069] The foreign matter inflow prevention device (206) is formed in a circular shape to be mounted on the discharge hole (204), and a number of holes (207) are formed to enable heat discharge, and a mesh (208) is mounted on the holes (207) to prevent foreign matter or insects from entering the lens mounting portion (101).

[0070] The upper cover (200) is formed in a cylindrical shape with the center side protruding upwards by a predetermined height from the edge side, and a third ventilation hole (201) communicating with the exhaust hole (204) may be further formed on the side of the protruding portion.

[0071] The rotary light fixture (1) according to the first embodiment of the present invention having the structure described above has the advantage that the light source opening / closing plate (131) for opening / closing the lens assembly surface (103) is individually rotated around each light source (121), so that replacement or repair of each light source is easy, and the lens module (151) is mounted on the light source opening / closing plate (131), so that replacement or management of the first and second lenses (152, 162) is easy.

[0072] In addition, in the rotary light fixture according to the first embodiment of the present invention, when power is supplied to the light source (121) and it emits light, the light irradiated from the light source (121) is first focused by the second lens (162), and the light passing through the second lens (162) is irradiated with a high focus density toward the front side of the first lens (152) by the first lens (152) having an aspherical surface (153) formed thereon, thereby forming a core light having a predetermined radius to a long distance, thereby increasing light visibility and increasing the viewing distance of the light, thereby improving light irradiation efficiency.
