Description

The present invention relates to lighting.

Conventionally, there are known lighting fixtures that have bird-repellent protrusions (bird-repellent needles) protruding from the top surface of the housing (see, for example, Patent Document 1).

JP 2017-183263 A

As with the conventional lighting fixtures described above, simply having the bird-proof hooks protrude from the top surface of the housing can result in areas that the bird-proof hooks cannot cover, resulting in areas where the bird-proof effect cannot be achieved.

Therefore, the object of the present invention is to provide a lighting fixture that can provide bird-deterrent effects over a wider area.

The lighting lamp according to one aspect of the present invention comprises a housing that houses a light source unit and a bird-proof hook that is attached to the housing, and the bird-proof hook extends in a position facing the top surface of the housing with its base end connected to the side of the housing.

The lighting fixtures of the present invention can provide bird-repellent effects over a wider area.

(Embodiment)
[Lighting]
First, a description will be given of the configuration of a lighting pole 1 equipped with a lighting lamp 10 according to the present embodiment. Fig. 1 is a conceptual diagram showing the external appearance of a lighting pole 1 equipped with a lighting lamp 10 according to the present embodiment.

As shown in FIG. 1, the lighting pole 1 includes a lighting lamp 10 that is provided at the top and emits light for illumination, and a support pole 2 that stands upright from the ground or the like. The lighting lamp 10 is an LED lighting lamp that uses an LED 321 (Light Emitting Diode: see FIG. 2) as a light source to illuminate the road, and is supported by the support pole 2. A power cable electrically connected to a power system such as a commercial power source is passed through the support pole 2 and electrically connected to the lighting lamp 10, thereby supplying power to the lighting lamp 10. The lighting lamp 10 may be configured to be attached to a structure other than a pole, rather than being installed on the support pole 2. The installation location of the lighting lamp 10 is not limited to the side of a road (sidewalk or roadway), and can be installed in any location, such as in a plaza such as a park, on the grounds of a factory, or in a gas station.

Next, the configuration of the illuminating lamp 10 will be described in detail. FIG. 2 is a cross-sectional view showing the configuration of the illuminating lamp 10 of FIG. 1. FIG. 3 is a plan view showing the lid portion 60 of the illuminating lamp 10 of FIG. 1 in an open state. FIG. 4 is a side view showing the lid portion 60 of the illuminating lamp 10 of FIG. 1 in an open state.

In the following description and drawings, the longitudinal direction of the illuminating lamp 10 is defined as the Y-axis direction. The left-right direction of the illuminating lamp 10 is defined as the X-axis direction. The thickness direction of the illuminating lamp 10 is defined as the Z-axis direction. The X-axis direction, Y-axis direction, and Z-axis direction intersect with each other (orthogonal in this embodiment). In the following description, for example, the positive X-axis direction indicates the side of the X-axis arrow (one side), and the negative X-axis direction indicates the opposite side to the positive X-axis direction (the other side). The same applies to the Y-axis and Z-axis directions.

In this embodiment, the light 10 is attached to the support 2 so that the Z-axis direction is tilted relative to the up-down direction (see FIG. 1). However, for ease of explanation, in the following explanation, the positive Z-axis direction may be referred to as the upward direction, and the negative Z-axis direction may be referred to as the downward direction.

As shown in Figures 2 to 4, the lighting fixture 10 includes a housing 20, a light source unit 30 housed in the housing 20, and a bird-repellent hook 40 attached to the housing 20.

[Case]
The housing 20 includes a main body 50 that is open at the top, and a lid 60 that is disposed above the main body 50 and opens and closes the open portion of the main body 50. In the following description, the end of the housing 20 in the negative Y-axis direction may be referred to as a base, and the end in the positive Y-axis direction may be referred to as a tip. The materials of the main body 50 and the lid 60 are not particularly limited, and may be formed from a metal material having high thermal conductivity, such as aluminum, an aluminum alloy, or a zinc alloy.

The main body 50 is formed in a generally box-like shape with an open top, and houses the light source unit 30. Specifically, the main body 50 has a thick base when viewed in the X-axis direction, and tapers toward the positive Y-axis direction (see FIG. 2). Also, when viewed in the Z-axis direction, the main body 50 has a narrow base and expands in width from approximately the center in the Y-axis direction. Hereinafter, the narrow part (base) of the main body 50 is referred to as the connecting part 51, and the expanded part (center to tip) is referred to as the lighting part 52. A partition wall 53 is provided between the connecting part 51 and the lighting part 52 to separate them. The partition wall 53 extends along the X-axis direction, and a cutout part 531 that is open at the top is formed in the center. A part of the light source unit 30 is housed in the cutout part 531.

The connecting portion 51 is a portion that is connected to the support pillar 2. The connecting portion 51 is provided with a fastening portion 511 to which the support pillar 2 is fastened (see FIG. 3, etc.). The fastening portion 511 is a substantially cylindrical member, and with a portion of the support pillar 2 inserted therein, the fastening portion 511 is fastened and connected to the portion of the support pillar 2 by tightening the fastening portion 511 with a bolt or the like.

In the connecting portion 51, a plurality of bosses 512a, 512b, 512c are arranged at a predetermined interval in the Y-axis direction on the inner bottom surface of the end portion in the negative X-axis direction. A female screw is formed on the upper end surface of each of the bosses 512a, 512b, 512c. Of the plurality of bosses 512a, 512b, 512c, the two bosses 512a, 512b in the positive Y-axis direction are for fixing the light source unit 30, and the remaining boss 512c is for fixing other members (such as cables) housed in the main body portion 50.

The lighting section 52 is a section that irradiates light from the light source unit 30. The lighting section 52 is provided with an enclosure wall 54 that is continuous with the partition wall 53 and that, together with the partition wall 53, surrounds the light source unit 30.

An opening 55 is formed on the underside of the illumination section 52, inside the partition wall 53 and the surrounding wall 54, to transmit light from the light source unit 30 to the outside. The opening 55 is generally rectangular when viewed in the Z-axis direction (plan view), and each corner is curved. The opening 55 is covered by a translucent cover 56.

The cover 56 is a translucent, flat, and generally rectangular member when viewed in the Z-axis direction (plan view). Each corner of the cover 56 is curved. In each of the cover 56 and the opening 55, a pair of sides face each other in the Y-axis direction and extend along the X-axis direction, and another pair of sides face each other in the X-axis direction and extend along the Y-axis direction.

The cover 56 is formed, for example, from glass or resin. The shape of the cover 56 is not limited to a substantially rectangular shape in a plan view, and may be a circular shape, an elliptical shape, a polygonal shape, etc. in a plan view. The cover 56 is also not limited to a flat plate shape, and may be a semi-elliptical sphere, a semi-sphere, a semi-cylinder, a semi-elliptical cylinder, etc. The material of the cover 56 is also not particularly limited.

A support surface 57 that supports the light source unit 30 from below is formed in a portion of the illumination section 52 above the opening 55. The support surface 57 extends along the periphery of the opening 55 and is formed in a planar shape. Specifically, the support surface 57 is formed in an inverted C shape when viewed in the Z-axis direction along one side of the opening 55 in the positive Y-axis direction and a pair of sides facing each other in the X-axis direction. The support surface 57 may extend around the entire circumference of the opening 55, or may extend intermittently. The support surface 57 may be formed in a continuous planar shape as a whole, or may be formed in a partially planar shape, as long as the portion that contacts the light source unit 30 is in surface contact.

The support surface 57 is provided with a restricting portion 70 to which a locking portion 80 that locks the light source unit 30 is attached. Specifically, two restricting portions 70 are provided at a portion of the support surface 57 in the positive Y-axis direction with a predetermined distance therebetween, and one restricting portion 70 is provided at each of the portions of the support surface 57 that face each other in the X-axis direction. Each restricting portion 70 is attached with one locking portion 80.

The lid 60 is an openable/closable lid that covers the light source unit 30 housed in the main body 50. The base of the lid 60 is connected to the main body 50 via a hinge 61. This allows the lid 60 to rotate around the X-axis direction with the hinge 61 as the center of rotation around the base. The lid 60 is formed in a box shape with an open bottom, and when closed, the bottom edge of the lid 60 overlaps the top edge of the main body 50 all around. A packing may be placed between the bottom edge of the lid 60 and the top edge of the main body 50 all around to improve airtightness.

The top surface of the lid 60 has a curved shape that protrudes upward when viewed in the X-axis direction (see FIG. 2). Therefore, the top surface of the end (tip) of the lid 60 in the positive Y-axis direction is an inclined surface that gradually slopes downward as it approaches the positive Y-axis direction.

A pressing portion 62 that protrudes in the negative Z-axis direction is provided on the inner top surface of the lid portion 60 at a position corresponding to the partition wall 53 of the main body portion 50. The pressing portion 62 is a plate-shaped portion that extends in the X-axis direction, and its lower end (tip) abuts against a part of the light source unit 30.

A through hole 64 is formed at the tip of the lid 60. A fixing screw 63 for fixing the lid 60 to the main body 50 is inserted into this through hole 64. The connection structure between the bird repellent needle 40 and the housing 20 will be described later.

[Light source unit]
2, the light source unit 30 integrally includes a base 31, a light source section 32, a terminal block 33, an illuminance sensor 34, and a power supply section 35. In other words, the light source unit 30 includes the base 31, the light source section 32, the terminal block 33, the illuminance sensor 34, and the power supply section 35 as a unit (module).

The base 31 supports the light source unit 32, the terminal block 33, the illuminance sensor 34, and the power supply unit 35. The base 31 includes a substrate 311, a vertical wall 312, and a base 313.

The substrate 311 is a flat substrate that supports the light source unit 32. Specifically, the substrate 311 supports the light source unit 32 on its underside. The substrate 311 is formed in a shape that covers the opening 55 of the illumination unit 52, and its outer periphery is supported from below by the support surface 57 of the illumination unit 52. At the positions corresponding to the respective regulating units 70 on the outer periphery of the substrate 311, rectangular recesses 314 are formed. The light source unit 30 is locked by the locking units 80 attached to the respective regulating units 70 being caught by the respective recesses 314. The locking form between the recesses 314 and the locking units 80 will be described later. The material of the substrate 311 is not particularly limited, but it is formed of a metal such as aluminum, for example.

The standing wall 312 is a portion that connects the substrate 311 and the base 313, and is a portion that supports the illuminance sensor 34. The standing wall 312 is attached to the end of the substrate 311 in the negative Y-axis direction. The standing wall 312 is an L-shaped metal plate when viewed in the X-axis direction, and includes a base 315 and a standing portion 316 bent relative to the base 315. The base 315 is a flat, rectangular portion that is parallel to the substrate 311 and is screwed to the end of the substrate 311 in the negative Y-axis direction. The standing portion 316 is a flat, rectangular portion that stands from the end of the base 315 in the negative Y-axis direction toward the positive Z-axis direction. The standing portion 316 is housed in the cutout portion 531 of the partition wall 53. The upper end of the standing portion 316 is pressed toward the main body portion 50 by the pressing portion 62 of the lid portion 60 when closed (see FIG. 2). This presses the light source unit 30 against the main body 50, making it more firmly fixed.

The base 313 is a portion that supports the terminal block 33. The base 313 is a flat metal plate that is attached to the top of the vertical wall 312 and extends in the negative Y-axis direction. A small piece-shaped first mounting portion 317 extending in the negative X-axis direction is provided at the end of the base 313 in the negative X-axis direction. A small piece-shaped second mounting portion 318 extending in the negative Y-axis direction is provided at the end of the base 313 in the negative Y-axis direction. The first mounting portion 317 is screwed to a boss 512a provided on the main body 50, and the second mounting portion 318 is screwed to a boss 512b provided on the main body 50. This makes it possible to fix the light source unit 30 more firmly to the main body 50. When the terminal block 33 is screwed to the main body 50 with a metal screw, the terminal block 33 is grounded to the main body 50 via the screw and the base 313.

The light source unit 32 is a plurality of LEDs 321 (light-emitting elements) mounted on the underside of the substrate 311. The plurality of LEDs 321 are arranged in a matrix on the substrate 311, but the number and arrangement of the LEDs 321 are not particularly limited. The LEDs 321 may be SMD (Surface Mount Device) type LEDs or COB (Chip On Board) type LEDs. In this embodiment, the light source unit 32 is entirely covered by a lens body 322 attached to the underside of the substrate 311. The lens body 322 is formed from a material such as a translucent resin or glass, and distributes the light emitted by each LED 321 so as to diffuse radially. The lens body 322 does not have to be provided on the substrate 311.

The terminal block 33 is a portion to which various cables (not shown) are connected. A power cable pulled in from outside the lamp 10 and a cable connected to the power supply unit 35 are connected to the terminal block 33.

The illuminance sensor 34 is a sensor that detects the illuminance of the environment surrounding the lighting lamp 10. The illuminance sensor 34 is disposed on the base 315 of the standing wall 312.

The power supply unit 35 is a power supply circuit that supplies power supplied from outside the illumination lamp 10 via the power cable, the terminal block 33, and the cable to the light source unit 32. The power supply unit 35 is supported on the upper surface of the substrate 311. The power supply unit 35 is connected to the illuminance sensor 34, and turns on/off the power supply to the light source unit 32 based on the detection result of the illuminance sensor 34. In other words, when the detection result of the illuminance sensor 34 is equal to or greater than a predetermined threshold, the power supply unit 35 turns off the power supply to the light source unit 32 to turn it off, and when the detection result of the illuminance sensor 34 is less than the predetermined threshold, the power supply unit 35 turns on the power supply to the light source unit 32 to turn it on.

[Bird-proof hook]
Fig. 5 is a perspective view showing the bird-proof needle 40 according to the embodiment. Fig. 6 is a cross-sectional view showing a connection structure between the bird-proof needle 40 and the housing 20 in Fig. 5.

As shown in Figures 2 to 6, the bird repellent needle 40 is a metal member having a base end 41 connected to the lid 60, and a pair of needles 42 extending from the base end 41. The base end 41 is a flat plate-shaped portion extending in the X-axis direction, and has a long notch in the X-axis direction at the center in the X-axis direction and the end facing the negative Y-axis direction. A pair of insertion holes 411 are formed in the base end 41 at positions sandwiching the notch in the X-axis direction.

As shown in FIG. 6, the fixing screw 63 inserted through the through hole 64 of the lid 60 is screwed into the screw hole 58 provided at the end of the body 50 in the positive direction of the Y axis. This fixes the lid 60 to the body 50 when closed. In addition, at the end of the lid 60 in the positive direction of the Y axis, a pair of screw holes (not shown) to which the base end 41 of the bird-proof hook 40 is fixed is formed on the lower end surface. Screws (not shown) inserted through a pair of insertion holes 411 of the base end 41 are screwed into these screw holes, thereby attaching the base end 41 to the lid 60. When the lid 60 is closed, the base end 41 is sandwiched between the planar first clamping surface 59 provided at the tip of the body 50 and the planar second clamping surface 69 provided at the tip of the lid 60. In other words, the base end 41 of the bird-proof hook 40 is connected to the side of the tip side of the housing 20. In addition, when closed, the base end 41 is clamped between the first clamping surface 59 of the main body 50 and the second clamping surface 69 of the lid 60, so that even if the screw for fixing the base end 41 of the bird-proof hook 40 falls off, the bird-proof hook 40 can be prevented from falling.

The pair of needles 42 are arranged at a predetermined interval in the X-axis direction, and extend from the base end 41 in the Z-axis positive direction and the Y-axis negative direction. The tip of each needle 42 is arranged at a position corresponding to the vertex of the top surface of the lid 60 (see FIG. 2). In addition, each needle 42 has a bending point 421 at a portion closer to the base end 41 from the center. Due to this bending point 421, each needle 42 extends in a position facing the top surface while following the top surface of the end of the lid 60 in the Y-axis positive direction. In this way, each needle 42 extends from the side of the tip side of the housing 20 in a position facing the top surface of the housing 20 (lid 60), so that it can face the side and part of the top surface of the housing 20. This makes it possible to block birds that try to land on the side or top surface of the housing 20. Since each needle 42 is a thin and long portion, it is difficult for birds to land on each needle 42 itself. Even if a bird lands on each needle 42, the weight of the bird will cause each needle 42 to vibrate, preventing the bird from staying there.

As shown in FIG. 1, when the housing 20 is viewed as a whole, when the connecting portion 51 is connected to the support 2, it can be said that the base of the housing 20 is connected to the support 2. The housing 20 is in a position where the tip is higher than the base. In this position, the body 50 is also tilted so that the tip faces upward, so that the light emitted from the opening 55 illuminates the ground further away from the support 2. At this time, the top surface of the tip of the housing 20 (lid portion 60) is closer to the horizontal plane than when the housing 20 is not tilted, making it easier for birds to land. As described above, each needle portion 42 extends from the side of the tip of the housing 20 and faces the side of the tip of the housing 20 and the top surface of the tip, so that it is possible to reliably exert a bird-repellent effect on the area where birds are likely to land.

[Effects, etc.]
As described above, with the base end 41 of the bird-proof hook 40 connected to the side of the housing 20, each needle 42 extends in a position facing the top surface of the housing 20, so that each needle 42 faces not only the top surface of the housing 20 but also the side portions, from the side portions to the top surface of the housing 20. Therefore, the bird-proof effect can be exerted over a wider range than when the bird-proof hooks protrude from the top surface of the housing 20.

In addition, when the lid 60 closes the main body 50, the base end 41 of the bird-proof hook 40 is sandwiched between the main body 50 and the lid 60, preventing the bird-proof hook 40 from falling off and improving safety.

In addition, because the base end 41 of the bird-proof hooks 40 is connected to the tip of the housing 20, when the housing 20 is attached to the support 2 so that the tip is higher than the base, each hook 42 can be reliably placed opposite the upper surface of the tip of the housing 20, which is close to the horizontal plane. This makes it possible to reliably exert the bird-proofing effect on areas where birds are likely to land.

Here, it is also possible to connect the base end 41 of the bird-proof hook 40 to the base of the housing 20, but the base is provided with a mechanism (such as a hinge 61) for opening the lid 60, and so there are structural and installation space limitations. On the other hand, the tip of the housing 20 is the part that is opened, and the aforementioned limitations are minimal. For this reason, it is possible to easily connect the base end 41 of the bird-proof hook 40 to the housing 20.

Furthermore, during maintenance, the worker may open the lid 60 on the support 2, but if the base end 41 of the bird-proof hook 40 is connected to the tip of the lid 60, the base end 41 of the bird-proof hook 40 will be the furthest from the main body 50, and the hook 42 will also be in a position away from the main body 50 (see FIG. 4). Since maintenance is mainly performed on each part inside the main body 50, it is possible to prevent the bird-proof hook 40 from interfering with the maintenance work. The base end 41 of the bird-proof hook 40 may be attached to a side part other than the tip of the lid 60. Even in this case, the bird-proof hook 40 will be away from the main body 50 when the lid 60 is opened, so that it is possible to prevent the bird-proof hook 40 from interfering with the maintenance work.

(others)
Although the illumination lamp 10 according to the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. In other words, the embodiment disclosed here is illustrative in all respects and is not restrictive, and the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the claims.

For example, in the above embodiment, the housing 20 is fixed to the support 2, but the housing 20 may be connected to the support 2 so that the angle can be adjusted. Specifically, the connecting portion 51 at the base of the housing 20 is connected to the support 2 so that the angle can be adjusted around the X-axis direction so that the base end 41 of the bird-proof hook 40 can move up and down. More specifically, the fastening portion 511 at the connecting portion 51 is angle adjustable around the X-axis direction. This makes it possible to adjust the illumination range of the lighting lamp 10. Even if the angle of the housing 20 is adjusted, the tip of the housing 20 is basically positioned above the base. In other words, in either position, the top surface of the tip of the housing 20 (lid portion 60) is closer to the horizontal plane than when the housing 20 is not tilted, making it easier for birds to land. Each needle 42 extends from the side of the tip of the housing 20 and faces the side of the tip of the housing 20 and the top surface of the tip, so it is possible to reliably exert a bird-repellent effect on areas where birds tend to land. In this way, even with a housing 20 that can be adjusted to any angle, it is possible to reliably exert a bird-repellent effect on areas where birds tend to land.

In addition, in the above embodiment, the light source unit 32 is unitized with other parts, but the light source unit may be housed in the housing 20 in an ununitized state.

In addition, in the above embodiment, the light source unit 32 is described as being composed of a plurality of LEDs 321, but the light source unit may be composed of a light source other than an LED.

In the above embodiment, the bird-proof hook 40 has a pair of needle portions 42. However, the number of needle portions 42 that the bird-proof hook 40 has may be one or three or more.

In the above embodiment, the tip of each needle 42 is disposed at a position corresponding to the apex of the top surface of the lid 60. However, the tip of each needle may be disposed at a position corresponding to the base end of the lid 60. In this case, the bird repellent effect can be achieved over a wider range.

In the above embodiment, the base end 41 of the bird-proof hook 40 is connected to the side of the tip end of the housing 20. However, the base end 41 of the bird-proof hook 40 may be connected to any part of the side of the housing 20. For example, the base end 41 of the bird-proof hook 40 may be connected to the side of the base side of the housing 20, or to the side of the center in the Y-axis direction. When the base end 41 of the bird-proof hook 40 is connected to the side of the center in the Y-axis direction, the connecting part 51 of the housing 20 may be connected to the support 2 so that the angle of the base end 41 can be adjusted around the Y-axis direction so that the base end 41 moves up and down. Even in this case, the needle part 42 extends from the side of the center of the housing 20 in the Y-axis direction and faces the side of the center of the housing 20 and the upper surface of the center, so that the bird-proof effect can be reliably exerted on the part where birds are likely to land.

In addition, in the above embodiment, the base end 41 of the bird repellent hook 40 is connected to the cover 60, but it may be connected to the main body 50.

The bird-repellent effect can also be further improved by applying a weak electric current to the bird-repellent needle 40.

In addition, any combination of the above embodiments and their variations is also included within the scope of the present invention.
