<First embodiment>
FIG. 1 is a perspective view showing an outline of an emergency marker light 1 according to a first embodiment of the invention. FIG. 2 is a six-sided view showing a schematic configuration of the emergency signal light 1, (A) is a front view, (B) is a top view, (C) is a bottom view, (D) is a left side view, ( E) is a right side view, and (F) is a rear view. FIG. 3 is a perspective view showing an outline of the emergency signal lamp 1 with the housing lid 14 (described in detail later) opened, and is an exploded view of the essential parts.

Hereinafter, the direction (vertical direction) substantially orthogonal to the ground (mounting surface) on which the emergency marker light 1 is mounted is defined as the z direction, and the center point c1 of the hole 15 and the center point c2 of the lamp body 12 are connected. The y-direction is defined as a direction substantially parallel to the dashed line ax (described in detail later), and the x-direction is defined as a direction substantially orthogonal to the y-direction and the z-direction.

The emergency marker light 1 is installed on a runway and used in an emergency, and mainly has a housing 10 , light emitting parts 21 , 22 , 23 , a hinge 31 and a fixing part 32 .

The housing 10 mainly has a substantially flat bottom surface 11 to be placed on the ground, and a lamp part 12 provided on the upper side of the bottom surface 11 . The housing 10 is made of a metal such as iron or aluminum alloy so as to withstand a wind speed of approximately 90 m/sec when placed, has a weight of approximately 5 kg or more, and has a height H from the placement surface. (See FIG. 2) is approximately 45 mm to approximately 70 mm.

A substantially circular hole 15 is formed in the bottom surface 11 . The hole 15 is arranged such that the position in plan view (the position viewed in the z direction) is different from the position of the lamp body 12 . A foldable joint 100 (see FIG. 5), which is a mounting member, is inserted into the hole 15 . The emergency indicator light 1 is attached to the foldable joint 100 through the hole 15 . It is desirable that the hole 15 and the lamp body 12 are separated as much as possible so that the foldable joint 100 and the lamp body 12 do not interfere with each other. In the present embodiment, the distance L (see FIG. 1) between the center c1 of the hole 15 and the center c2 of the lamp body 12 is approximately 200 mm to approximately 230 mm. The attachment of the emergency marker light 1 to the foldable joint 100 will be described in detail later.

The bottom surface 11 mainly has a main bottom surface 11a and a movable portion 11b. The main bottom surface 11 a has a substantially plate shape and is provided below the lamp body portion 12 . The movable portion 11b has a substantially plate shape and is provided on substantially the same plane as the main bottom surface 11a.

A substantially semicircular first hole 15a is formed in the main bottom surface 11a, and a substantially semicircular second hole 15b is formed in the movable portion 11b. 1 to 3 show the closed state in which the main bottom surface 11a and the movable portion 11b face each other, and the first hole 15a and the second hole 15b are integrated to form the hole 15. FIG.

A plurality of continuous irregularities 15c are formed on the side surface of the first hole 15a. However, the unevenness 15c only needs to be provided on the side surface of the hole 15, and the position and number of the unevenness 15c are not limited to this.

The bottom surface 11 is provided with a hinge 31 for rotatably attaching the movable portion 11b to the main bottom surface 11a, and a fixing portion 32 for fixing the main bottom surface 11a and the movable portion 11b in the closed state.

The fixing portion 32 is a so-called snap lock (snap lock) that is fixed by hooking one end on a projection and tilting the lever. However, the fixed part 32 is not limited to the snap lock.

The lamp body portion 12 has a thick plate shape in side view, and a substantially circular shape in plan view. In other words, the lamp body portion 12 has a thick disc shape. Here, a thick plate-like member is a plate-like member that is wider than it is high when viewed from the side, and that the width (or diameter) is approximately four times or more the thickness.

The lamp body 12 mainly has a substantially cylindrical side surface 13 and a housing lid 14 covering the upper end surface, and the inside is hollow. The housing lid 14 is rotatable about the hinge 33 with respect to the side surface 13 . The side surface 13 and the housing lid 14 are fixed with a snap lock 34 .

Light-emitting portions 21 , 22 and 23 are provided on the side surface 13 . The light emitting portions 21 , 22 , and 23 are provided on the outer peripheral surface of the side surface 13 and emit light radially outward of the lamp body portion 12 . The light-emitting portions 21 and 22 are arranged at symmetrical positions about a line ax connecting the center point c1 of the hole 15 and the center point c2 of the lamp body portion 12 in a plan view (viewed from the z-direction). It is Further, in plan view, the angle formed by the line ax and the line connecting the light emitting portions 21 and 22 and the center point c2 is an acute angle. The light emitting part 23 is arranged on the line ax. That is, the light-emitting portions 21, 22, and 23 are provided at intervals of approximately 60 degrees. Thereby, it is possible to project light in all directions in the horizontal direction.

Since the light emitting units 21, 22, and 23 have the same configuration, the light emitting units 21, 22, and 23 will be explained using the light emitting unit 23 as an example. As shown in FIG. 3, the light emitting section 23 mainly has an LED 23a, a lens 23b, and a lens packing 23c. The LED 23a is a light-emitting element provided on the substrate, and emits white light, for example. The lens 23b diffuses the light emitted from the LED 23a.

A battery 43 for supplying power to the light emitting units 21 , 22 , 23 is provided inside the lamp unit 12 . The battery 43 is various batteries such as a dry battery and a rechargeable battery. The battery 43 is provided inside the lamp unit 12 in a state where it is placed in the battery box 42 . Battery 43 is electrically connected to substrate 46 . Further, the substrate 46 and the light emitting portions 21, 22, and 23 are connected by wiring (not shown) through the holes 13a.

The LED 23a is provided on the outer peripheral surface of the side surface 13, and the lens 23b is provided on the outer peripheral surface of the side surface 13 so as to cover the LED 23a. A lens packing 23c is provided on the rear surface of the lens 23b, and the lens 23b is provided on the outer peripheral surface of the side surface 13 to prevent water or the like from entering the inside of the lens 23b (around the LED 23a).

4A and 4B show elevation angles of the light-emitting units 21, 22, and 23. FIG. The case where it is used as a luminous intensity runway light is shown. Although FIG. 4 shows the elevation angle of the light emitting unit 22, the elevation angles of the light emitting units 21, 22, and 23 are the same.

When the emergency beacon light 1 is used as an emergency runway light as shown in FIG. It is approximately 5 degrees.

As shown in FIG. 4B, when the emergency marker light 1 is used as a low-luminance runway light, the elevation angles of the light-emitting portions 21, 22, and 23 are approximately 0 to approximately 7 degrees, and the center of the elevation angle is approximately 3.5 degrees.

Whether the emergency marker light 1 is used as an emergency runway light or a low-luminance runway light, the center of the elevation angle is greater than 0 degrees. Therefore, even if the mounting surface is tilted, the predetermined luminous intensity is satisfied. In this embodiment, the predetermined luminous intensity is satisfied even if the mounting surface is inclined by several degrees.

Returning to the description of FIG. A receiver 41 for receiving light or radio waves from the outside is provided on the upper surface of the housing lid 14 . Since the position and shape of the receiving section 41 are not limited to those illustrated, the receiving section 41 is indicated by a chain double-dashed line in FIG. Further, the side surface 13 is provided with a changeover switch 45 for switching between lighting and extinguishing.

5A and 5B are diagrams for explaining the attachment of the emergency marker light 1 to the foldable joint 100. FIG. 5A shows the state during attachment, and FIG. 5B shows the state after attachment. The foldable joint 100 is configured such that the upper portion (cylindrical portion 103) from the cutting groove 101 is broken when a load exceeding a certain level is applied. A hexagonal portion 102 having a substantially hexagonal shape in a plan view provided below the cutting groove 101 of the foldable joint 100 is inserted into the hole 15 .

As shown in FIG. 5A, the fixed portion 32 is removed and the movable portion 11b is rotated about the hinge 31 from the closed state to separate the hole 15 into the first hole 15a and the second hole 15b. After that, the hexagonal portion 102 is pressed against the first hole 15a, the movable portion 11b is rotated about the hinge 31 to return to the closed state, and the fixing portion 32 is stopped to fix the main bottom surface 11a and the movable portion 11b. As a result, the emergency signal lamp 1 can be attached to the hexagonal portion 102 located near the mounting surface while the heavy emergency signal lamp 1 is placed thereon. Moreover, it is not necessary to use a tool for mounting the emergency indicator light 1, and the mounting is easy.

Since a plurality of unevennesses 15c are formed in the first hole 15a, the corners of the hexagonal portion 102 are held by the unevennesses 15c. As a result, the emergency signal light 1 does not move in the rotational direction with respect to the hexagonal portion 102 .

As shown in FIG. 5B, when the emergency marker light 1 is attached to the foldable joint 100, the marker light 110 is provided on the foldable joint 100. As shown in FIG. A marker light 110 is attached to the cylindrical portion 103 . In the emergency marker light 1, the positions of the lamp body 12 and the hole 15 are different in plan view, and the height from the mounting surface (ground) of the lamp body 12 is approximately 45 mm to approximately 70 mm. The lamp 110 and the lamp body part 12 do not interfere with each other, and the emergency marker lamp 1 does not interfere with the function of the marker lamp 110.例文帳に追加

Further, since the hexagonal portion 102 is inserted into the hole 15, the emergency marker light 1 remains attached to the foldable joint 100 even in an emergency when the marker lamp 110 is damaged together with the cylindrical portion 103. Therefore, the emergency marker light 1 can be used in an emergency.

FIG. 6 is a block diagram showing the electrical configuration of the emergency marker light 1. As shown in FIG. The emergency marker light 1 has a control section 44 electrically connected to the receiving section 41 and the changeover switch 45 . The receiving unit 41 receives information (for example, light) transmitted from the remote controller 49 and outputs the information to the control unit 44 . The control unit 44 is electrically connected to the light emitting units 21 , 22 and 23 and switches between lighting and extinguishing of the light emitting units 21 , 22 and 23 based on the reception result of the receiving unit 41 . Further, the control unit 44 switches the light emission mode (emergency runway light or low-luminance runway light) of the light-emitting units 21 , 22 , 23 based on the reception result in the reception unit 41 . As a result, the light emitting units 21, 22, and 23 can be easily turned on in an emergency. Also, a plurality of emergency marker lights 1 can be operated at once.

According to the present embodiment, by providing the emergency indicator light 1 in the hexagonal portion 102 below the cut groove 101 of the foldable joint 100, the upper portion (cylindrical portion 103) of the foldable joint 100 from the cut groove 101 The emergency marker lamp 1 can be used even in an emergency when it is damaged. Further, since the marker light 110 and the lamp body part 12 do not interfere with each other, the emergency marker light 1 does not interfere with the function of the marker light 110 in normal times.

Although there are three light emitting units 21, 22, and 23 in this embodiment, the number of light emitting units is not limited to this. The emergency marker light 1 may have one or a plurality of light emitting parts. However, in order to irradiate light over a wide range, it is desirable that the two light emitting parts be arranged at symmetrical positions with respect to the line ax. In addition, in order to project light in all horizontal directions, the emergency signal light 1 has at least three light-emitting portions as shown in FIGS. It is desirable to arrange them at symmetrical positions with respect to the axis of symmetry, make an acute angle between the line connecting these light emitting parts and the center point c2 and the line ax, and arrange the remaining one on the line ax.

In addition, although the emergency indicator light 1 is provided on the foldable joint 100 in the present embodiment, the emergency indicator light 1 can be attached to a mounting member other than the foldable joint 100 . FIGS. 7A and 7B are diagrams for explaining how to attach the emergency marker light 1 when a hole is formed in the ground. FIG. 7A shows the mounting member 120, and FIGS. 2 shows a state in which the mounting member 120 is provided, and (D) shows a state in which the emergency signal lamp 1 is mounted on the mounting member 120. FIG.

As shown in FIG. 7A, the mounting member 120 has a mounting fixture 121 and bolts 122 and 123 . The fixture 121 has a block shape as a whole, and has a base portion 121 a provided inside the holes 131 and 132 and a projecting portion 121 b projecting upward from the holes 131 and 132 .
