Description

[Technical Field]

[0001] The present disclosure relates to a sight, a lamp, a flashlight, a flashing device, and a method for adjusting the orientation of a lamp. [Background technology]

[0002] When a lamp has directionality, adjusting the direction of light emission is important. For example, a flashing light used to guide aircraft landings emits light into the sky so that the runway can be seen by aircraft preparing to land. Generally, multiple flashing lights are placed on both sides of a runway along the runway light array to indicate the runway's location with light. To adjust the light emission direction, a flashing light is typically equipped with an elevation angle adjustment device that adjusts the vertical elevation angle and a sight that adjusts the azimuth left and right. For example, Patent Document 1 discloses a flashing light device that allows the elevation angle of the flashing light to be adjusted on a mounting arm. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 04-117018 Summary of the Invention [Problem to be solved by the invention]

[0004] A sight often consists of a rear sight and a rear sight. The flashlight's azimuth can be adjusted by visually viewing the rear sight through the rear sight and aligning the rear sight with the reference point for azimuth adjustment. However, the reference point for azimuth adjustment is horizontal, so when the elevation angle is adjusted and the flashlight's light is directed upward, the sight attached to the flashlight tilts. As a result, the rear sight becomes invisible when viewed horizontally through the rear sight. This problem is not limited to flashlights, but is a common issue with directional lamps in general.

[0005] Therefore, the present disclosure aims to provide a sight, lamp, flashlight, flash device, and lamp azimuth adjustment method that allows the sight to be seen from the rear sight in the horizontal direction even when the light irradiation direction of the lamp is tilted upward. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the sight of the present disclosure includes a rear sight and a front sight, the rear sight and the front sight being located on a single reference line, the reference line being tilted with respect to the horizontal direction so that the front sight is downward relative to the rear sight, and the front sight having a height that allows it to be visually confirmed when attempting to view the front sight in the horizontal direction from the rear sight.

[0007] The lamp of the present disclosure is a lamp that includes the optical sight of the present disclosure.

[0008] A flashlamp of the present disclosure is a flashlamp that includes a lamp of the present disclosure.

[0009] The aircraft landing guidance flashing device of the present disclosure is a flashing device including the flash lamp of the present disclosure.

[0010] The lamp azimuth adjustment method of the present disclosure is a method for adjusting the azimuth of the lamp, which is the direction of light irradiation, after adjusting the elevation angle of the lamp, by using the sight, visually observing the front sight from the rear sight, and aligning the front sight with an azimuth reference, thereby adjusting the azimuth. This is a method for adjusting the lamp orientation. [Effects of the Invention]

[0011] According to the present disclosure, even if the light irradiation direction of the lamp is tilted upward, the front sight can be seen from the rear sight in the horizontal direction. [Brief explanation of the drawings]

[0013] In the sight of the present disclosure, the rear sight and the front sight may be arranged on the same plate-like member.

[0014] In the sight of the present disclosure, the rear sight may have a concave shape and the front sight may have a convex shape.

[0015] The lamp of the present disclosure may include a light source and a housing, the light source being disposed within the housing, the housing having an opening through which light from the light source can exit, and the sight being attached to the outside of the housing. In the above embodiment, the light source may be an LED module. In the above embodiment, the lamp may further include a light distribution member disposed within the housing, the light distribution member distributing and irradiating light from the light source. In the above embodiment, the lamp may include an elevation angle adjustment unit for adjusting the elevation angle formed when the light irradiation direction is directed upward relative to the horizon, and the elevation angle adjustment unit adjusts the elevation angle of the housing. The light distribution member may be, for example, a reflector, a lens, or the like.

[0016] In the lamp orientation adjustment method of the present disclosure, the orientation reference may be at least one of the rear sight and the front sight of the sight of the other lamp.

[0017] The scope of application of the sight of the present disclosure is not particularly limited, and may be, for example, as mentioned above, a lamp, a flashlight, and an airplane takeoff guidance flash device, as well as other lamps and the like that require adjustment of elevation angle and azimuth.

[0018] Next, embodiments of the present disclosure will be described with reference to FIGS. 1 to 11. The present disclosure is not limited or restricted in any way by the following embodiments. In FIGS. 1 to 11, the same parts are denoted by the same reference numerals. The descriptions of the embodiments can be mutually incorporated. In addition, for the sake of convenience, the structures of the parts are shown in simplified form in the drawings, and the dimensional ratios of the parts may be shown schematically and different from the actual ones.

[0019] [Embodiment 1] An example of a sight according to the present disclosure is shown in FIGS. 1, 2, and 3. As shown, the sight 1 has two rectangular projections 1a spaced apart at one end of a rectangular plate-like member 1c, forming a concave sight, and a single projection at the other end of the long side, forming a front sight 1b. The sight and front sight are arranged on a single reference line. Hereinafter, the two projections 1a and the gap between them may be referred to as the front sight 1a. In FIGS. 1, 2, and 3, arrows indicate the line of sight for aiming. To adjust the azimuth of the sight 1, the front sight 1b is viewed through the gap in the front sight 1a and aligned with the reference point for azimuth alignment (azimuth reference). In the sight 1, the height hb of the front sight 1b is higher than the height ha of the sight 1a. Therefore, in this sight 1, the reference line is tilted relative to the horizontal direction so that the front sight 1b is downward relative to the rear sight 1a, and when one tries to visually view the front sight 1b horizontally from the rear sight 1a, the front sight 1b can be confirmed visually.

[0020] [Embodiment 2] Next, an example of the lamp, flash lamp, and flash device of the present disclosure will be described with reference to Figs. 4 to 10. This embodiment is an example in which the lamp is applied to the flash lamp, and the flash lamp is applied to the flash device. Fig. 4 is a front view of the flash device, and Fig. 5 is a side view of the flash device. Figs. 6 and 7 are perspective views of an attachment device for the flash device, and Fig. 8 is a perspective view of the flash device. Figs. 9 and 10 are explanatory diagrams for adjusting the elevation angle and azimuth of the flash device.

[0021] 4, 5, and 8, a flashlight (lamp) 31 is attached to a mounting device to form a flashlight device 30. The mounting device is composed of a pair of mounting arms 11 and legs 14.

[0022] 4 and 5, flash lamp 31 has an LED module (light-emitting unit) 313 and a reflector 314 for distributing light from the LED module arranged inside housing 311. Housing 311 has an opening on the front, which is covered with a transparent cover (front glass) 315, and transparent cover 315 is fixed to the opening of housing 311 by a mounting frame 312. Also, sight 1 is arranged on the top of mounting frame 312 with the sight side facing the light irradiation side.

[0023] In the present disclosure, the light-emitting unit of the flash lamp is not limited to an LED module, and may be, for example, a high-intensity lamp such as a xenon lamp. When an LED module is used, a heat sink, heat fins, or the like may be used to discharge heat generated by the LED to the outside. Furthermore, the light distribution member may be, for example, a lens in addition to a reflector.

[0024] Figure 8 shows a perspective view (a) from the side of the light irradiation direction (front side) and a perspective view (b) from the side opposite to the light irradiation direction (rear side) of the flash device 30 of Figures 4 and 6. As shown in the perspective view (b), a connection part 32 is arranged on the back side of the housing, allowing the flash lamp 31 to be connected to a controller and a power supply device (not shown).

[0025] As shown in FIG. 6, the mounting device 10 of this embodiment includes a pair of mounting arms 11 and a flashlight fixing plate 12. The pair of mounting arms 11 includes a first mounting arm 11a, a second mounting arm 11b, and a bridging plate 11c. The first mounting arm 11a and the second mounting arm 11b are bridged by the bridging plate 11c at their bottom ends (downward in FIG. 6) so as to be approximately perpendicular to the surface of the bridging plate 11c. The first mounting arm 11a, the second mounting arm 11b, and the bridging plate 11c are integrally molded. The fixing plate 12 is a U-shaped plate with a substantially arc-shaped convex portion in the center of the bottom side of the U and a concave portion (notch) adjacent to the convex portion. The outer surface of one end of the fixing plate 12 is fixed to the inner surface of the upper portion (upper side in FIG. 6) of the first mounting arm 11a. The outer surface of the other end of the fixing plate 12 is fixed to the inner surface of the upper part (upper side in FIG. 6) of the second fixing arm 11b. The fixing plate 12 is supported by the first fixing arm 11a and the second fixing arm 11b so that the angle of the flash lamp is set to a predetermined angle with the flash lamp fixed to the fixing plate 12. In the mounting device 10, for example, the bottom surface of the bridging plate 11c is fixed directly or indirectly to the installation surface, thereby installing the mounting device 10. An example of the indirect fixing is fixing via the legs (base) 14 shown in FIGS. 4 and 5.

[0026] Next, FIG. 7 shows an example of the configuration of another mounting device different from that shown in FIG. 6. As shown in FIG. 7, mounting device 20 includes angle adjustment means 13, legs 14, and angle confirmation means 15 in addition to the configuration of mounting device 10 shown in FIG. 6. The angle adjustment means 13 allows adjustment of the elevation angle of the flashlight. The angle adjustment means 13 includes a rotation shaft 13a, a bearing (not shown) for the rotation shaft 13a, and a moving shaft 13b, a moving hole 13c for the moving shaft 13b. In mounting device 20, fixing plate 12 is not directly supported by the pair of mounting arms 11, but is indirectly supported via angle adjustment means 13. Furthermore, fixing plate 12 has an upward (upper side in FIG. 7) protrusion at the mounting portion with first mounting arm 11a and second mounting arm 11b. In mounting device 20, the first mounting arm 11a and second mounting arm 11b are provided with the bearings. The rotating shaft 13a is a screw-like member and also serves as the rotating shaft fixing means. The rotating shaft 13a is inserted through the bearing formed in the first mounting arm 11a or the bearing formed in the second mounting arm 11b, and is connected to the fixing plate 12. The moving hole 13c is an arc-shaped through-hole centered on the rotating shaft 13a, formed in the first mounting arm 11a and the second mounting arm 11b above the bearing (upper side in FIG. 7). The moving shaft 13b is a screw-like member and also serves as the moving shaft fixing means. The moving shaft 13b is inserted through the moving hole 13c formed in the first mounting arm 11a or the moving hole 13c formed in the second mounting arm 11b, and is connected to the fixing plate 12. The moving shaft 13b is movable within the moving hole 13c, centered on the rotating shaft 13a. The legs 14 are connected to the bridge plate 11c on the bottom side of the center of the bridge plate 11c so that the mounting device 20, which includes the pair of mounting arms 11, can be installed on an installation surface. The angle confirmation means 15 includes an angle display unit 15a and a needle 15b. The angle display unit 15a is located at the upper end of the light-emitting unit fixing plate 12 on the first mounting arm 11a side. The needle 15b is located at the upper end of the first mounting arm 11a on the fixing plate 12 side so as to face the center of the angle display unit 15a. Except for these points, the mounting device 20 has the same configuration as the mounting device 10 in FIG. 6, and the description thereof can be used.

[0027] The angle display unit 15a is not particularly limited, and may, for example, display a scale indicating the angle of the fixing plate 12 relative to the pair of mounting arms 11. The angle display unit 15a is plate-shaped, but the shape, size, material of which it is made, etc. are not particularly limited. The needle 15b is not particularly limited, and may, for example, be a member that indicates the angle of the fixing plate 12 relative to the pair of mounting arms 11 when combined with the angle display unit 15a. The needle 15b is needle-shaped, but the shape, size, material of which it is made, etc. are not particularly limited.

[0028] In the mounting device 20, when the rotating shaft 13a and the moving shaft 13b are not fixed, for example, the rotating shaft 13a rotates, and the moving shaft 13b moves within the moving hole 13c around the rotating shaft 13a in a manner corresponding to the rotation direction of the rotating shaft 13a. Also, one end of the rotating shaft 13a and the moving shaft 13b are connected to the fixing plate 12 as described above. Therefore, the fixing plate 12 rotates around the axis connecting the two rotating shafts 13a in accordance with the rotation of the rotating shaft 13a and the movement of the moving shaft 13b. Therefore, when the rotating shaft 13a and the moving shaft 13b are not fixed, for example, by adjusting the angle of the light-emitting unit fixing plate 12 with respect to the pair of mounting arms 11, the angle (elevation angle) of the flash lamp can be adjusted. Furthermore, in the mounting device 20, the pair of mounting arms 11 support the fixing plate 12 at two points, the rotating shaft 13a and the moving shaft 13b, when adjusting the angle of the fixing plate 12 relative to the pair of mounting arms 11. Therefore, with the mounting device 20, for example, the angle (elevation angle) of a flashlight can be adjusted more precisely. Furthermore, as described above, the rotating shaft 13a and the moving shaft 13b are screw-shaped members. Therefore, after adjusting the angle of the flashlight, for example, the positional relationship between the fixing plate 12 and the pair of mounting arms 11 can be fixed by fixing at least one of the rotating shaft 13a and the moving shaft 13b, and thereby the angle of the fixing plate 12 relative to the pair of mounting arms 11 can be fixed. Therefore, for example, before installing the flashlight, the pivot axis 13a and the moving axis 13b are left in an unfixed state, and the angle of the light-emitting unit fixing plate 12 relative to the pair of mounting arms 11 is adjusted, and after the adjustment, the pivot axis 13a and the moving axis 13b are fixed, thereby eliminating the need to adjust the angle of the flashlight when the flashlight is attached to the mounting device 20.

[0029] The pair of mounting arms 11 and the fixing plate 12 may be made of a material such as metal, such as aluminum or stainless steel, or resin.

[0030] Next, an example of adjusting the direction of the flashlight 31 using the sight 1 will be described with reference to FIGS.

[0031] FIG. 9 is a view of the sight 1 from the front side (the side from which the light is emitted) of the flashlight 31. As shown in the figure, the sight 1b can be seen through the gap in the sight 1a of the sight 1. As shown in FIG. 10(a), when the elevation angle of the flashlight 31 is 0 degrees relative to the horizon L1 (the direction of light emission is horizontal), as shown in FIG. 10(b), if the flashlight 31 is tilted upward so that the light emission direction L2 is directed upward, the elevation angle becomes α relative to the horizon L1. In the case of FIG. 10(b), in order to adjust the azimuth of the flashlight, the gap in the sight 1a of the sight 1 requires the sight 1b to be seen horizontally. However, because the height of the sight 1b is at a height where it can be seen, the sight 1b can be seen. As a result, the illumination azimuth of the flashlight 31 (the direction of light emission in the horizontal plane) can be adjusted by aligning the sight 1b with the azimuth reference.

[0032] FIG. 11 shows an example in which the flashlight of the present disclosure is applied to an airfield lighting system (an airplane landing guidance flashlight device). In FIG. 11, the flashlight of the present disclosure is applied to a chained flashlight 30A and a runway end identification light 30B. As shown in the figure, runway end identification lights 30B are placed on both the left and right sides of the end of runway R on the landing approach side of airplane A. Further forward of the runway end identification lights 30B, multiple chained flashlights 30A are placed on an extension of the centerline (runway center) of runway R. The chained flashlight 30A has a configuration in which multiple lamps (flashlights) lined up horizontally are supported by poles (legs), which are fixed to the ground. The chained flashlight 30A projects light into the sky, pointing upward relative to the horizontal (at an elevation angle greater than 0 degrees) so that airplane A can recognize the location of the runway as it approaches for landing. Furthermore, in order to accurately indicate the position of the runway, the chained flashlight 30A must align its light projection direction (the direction of light projection on the horizontal plane) with the direction of the runway. For this reason, the elevation angle of the chained flashlight 30A is first adjusted so that the light projection direction is toward the sky, and then the direction of the chained flashlight 30A is adjusted using the sight 1 (front sight 1a or rear sight 1b) of the rear chained flashlight 30A as the direction reference. The runway end identification light 30B also points its light projection direction upward, and uses the sight to align its direction according to the direction reference that indicates the direction of the runway.

[0033] In this embodiment, the azimuth reference for the chained flashlight 30A is the sight of another chained flashlight 30A, but the present disclosure is not limited to this, and a reference object other than the sight may be used as the azimuth reference.

[0034] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
