Description

beacon

[0001] The present invention relates to a light fixture, and more particularly, to a light fixture capable of expanding the amount of light irradiated by means of a light path conversion structure having a vertically symmetrical structure.

[0002] Typically, beacons are installed on lighthouses, light buoys at sea, etc. to ensure safe navigation of ships.

[0003] Conventional incandescent bulb-based lighting fixtures operate by rotating a socket assembly containing multiple incandescent bulbs using a mechanical structure called a bulb changer. Furthermore, if the currently operating bulb fails, a motor mounted on the bulb changer automatically switches to a spare bulb.

[0004] However, these light bulb-type lights require frequent inspection and maintenance of the power supply due to inefficient use of power, and have the disadvantage of requiring frequent inspections on the manager's side due to the shortened lifespan of the battery.

[0005] Accordingly, recently, lights utilizing LEDs, which have higher brightness than incandescent bulbs, have been developed and are being used. These LED lights feature multiple light-emitting LED modules stacked on the upper portion of the light body. Fresnel lenses are also installed to parallelize the light emitted from the LED modules.

[0006] In this way, when using multiple LED modules, the structure becomes complex due to the installation of multiple LED modules and Fresnel lenses, and further, there is a problem that the manufacturing cost of the light fixture increases.

[0007] In addition, there is a problem that the use of a Fresnel lens is essential because there is no special method other than using a Fresnel lens to radiate the light emitted from the LED module into parallel light.

[0008] To address these issues, Korean Patent No. 10-1782264 proposes a lamp using a parabolic focal point fluorescent substance. However, this lamp also has a complex structure and has limitations in expanding the amount of light emitted.

[0009] The present invention was created to improve the above-mentioned problems, and its purpose is to provide a light fixture that can radiate light as a straight parallel light in a 360-degree (°) direction around the light fixture without using a Fresnel lens, while providing expandability of the amount of light irradiated.

[0010] In order to achieve the above object, a light fixture according to the present invention comprises: a support body having a lower support body, an upper support body spaced upwardly from the lower support body, and a connecting rod connecting the lower support body and the upper support body so as to support the upper support body in a spaced state with respect to the lower support body; at least one lower light source mounted on an upper surface of the lower support body and emitting light upward; at least one upper light source mounted on a lower surface of the upper support body and emitting light downward; a lower optical path changer coupled to the lower support body so as to surround the lower light source and convert the optical path of light emitted from the lower light source in a direction intersecting the extension direction of the connecting rod; An upper optical path converter is connected to the upper support body to surround the upper light source so as to convert the optical path of light emitted from the upper light source in a direction intersecting the extension direction of the coupling rod; and the lower optical path converter is formed to have a flange portion formed in a disk shape, a dome portion formed in a hemispherical shape with an outer diameter that gradually decreases as it extends upward from the flange portion, and a cylindrical portion that extends in a cylindrical shape from the upper portion of the dome portion and has a concave groove that is recessed downward from the upper end toward the center, and the upper optical path converter is formed in the same structure as the lower optical path converter and has a structure that is arranged vertically symmetrically.

[0011] Additionally, the lower optical path converter and the upper optical path converter can be formed of either glass or quartz.

[0012] Additionally, the concave groove of the cylindrical portion is formed as an aspherical surface.

[0013] In addition, the lower support body comprises a base portion formed in a disc shape; a central raised ring portion protruding upward in a cylindrical shape from the center of the base portion and having a module mounting groove formed on an upper surface thereof so as to be inserted downward and in which the lower light source is mounted, and at least one wire entry hole formed through the module mounting groove and exposed to the outside and communicating with the module mounting groove; an inner support guide portion protruding upward in a ring shape so as to be spaced apart from the central raised ring portion and concentrically surround the central raised ring portion; and an outer support guide portion protruding upward in a ring shape so as to be spaced apart from the inner support guide portion and concentrically surround the inner support guide portion; and the coupling rod is coupled through the coupling groove formed in a region between the outer support guide portion and an edge, and the lower optical path converter is mounted within the inner peripheral surface of the outer support guide portion and coupled through the base portion and the flange portion.

[0014] In addition, a collimating lens may be further provided between the lower light source and the lower optical path converter to focus the light emitted from the lower light source and radiate it upward.

[0015] According to the light fixture according to the present invention, light can be radiated as straight parallel light in the entire 360-degree (°) direction around the light fixture without using a Fresnel lens, and the light emitted from both the upper and lower sides can be horizontally converted into an optical path, thereby providing an advantage of expandability of the amount of irradiated light.

[0035] The upper support body (130) has an outer support guide ring portion (128) vertically arranged to face the outer support guide ring portion (128) of the lower support body (120).

[0036] The connecting rod (140) connects the lower support body (120) and the upper support body (130) to each other so as to support the upper support body (130) in a spaced state with respect to the lower support body (120).

[0037] Four connecting rods (140) are applied and fixedly connected through a nut (143) through a connecting groove (123) formed to penetrate vertically in the area between the outer support guide portion (128) of the base portion (122) and the edge.

[0038] The bonding rod (140) may be formed of a transparent material with high light transmittance in part or all of the area where light is irradiated.

[0039] The lower light source (150) is mounted in a module mounting groove (124a) formed on the upper surface of the central raised ring portion (124) of the lower support body (120) and emits light upward. A plurality of lower light sources (150) can be installed at equal intervals along the circumference of the lower support body (120) on the circuit board.
