Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aviation obstacle light arranged in a high-rise building such as a steel tower or a building lamp. More specifically, the present invention relates to an aircraft obstacle light in which a light emitting element such as an LED is applied as a light source.
[0002]
[Prior art]
In order to make aircraft and the like aware of the existence of high-rise buildings, high-rise buildings such as steel towers and buildings are provided with aviation obstruction lights at a predetermined altitude.
[0003]
Aviation obstruction light is generally a light source part consisting of an incandescent light bulb or a neon tube that emits light, a base part for supporting the light source part and being attached to the top or side wall of a high-rise building, A cover portion (also referred to as a globe) covering the light source, a power source portion for turning on or blinking the light source, and the like are included. A neon tube is a discharge tube filled with an inert gas that emits lamp light. In addition, as for the light source unit, an LED having a feature that the power consumption is smaller and the lifetime is longer than that of an incandescent bulb or a neon tube is often applied in recent years. In addition, the power supply terminal is provided in the base part, and many are comprised so that commercial power supply AC100V can be supplied. (For example, refer to Patent Document 1).

[Problems to be solved by the invention]
The power supply to the aviation obstacle light is generally performed by laying a power line up to the aviation obstacle light and connecting the power line to the power supply terminal of the aviation obstacle light. In addition, when installing aviation obstruction lights on steel towers in places where it is extremely difficult to lay power lines, such as in the back of mountains, the overhead ground wire is devised and the voltage induced in this overhead ground wire is used. In other words, a means for ensuring power supply by a so-called electrostatic induction power supply system is employed.
[0006]
However, with regard to the power supply of the aviation obstacle light, in the method of laying the power line, when the power supply facility is not in the vicinity of the aviation obstacle light, the power line is laid from a distance, while electrostatic induction In the power supply system, it is necessary to provide a control device that insulates the overhead ground wire over a predetermined section and boosts or rectifies the induced voltage. Therefore, with these methods, the construction of power supply facilities is complicated, the number of work is large, and the cost is high. Therefore, it is one effective means to operate the aviation obstruction light with an independent power source such as a solar battery, but the conventional aviation obstruction light is not so small in power consumption that an independent power source such as a solar cell can be applied. It was extremely difficult to apply this.
[0007]
As for power consumption, in the case of a low-light aviation obstacle light with a light intensity of 30 cd (candela) applied at an altitude of less than 90 m, if the light emitting element is a neon tube type, the power consumption is about 90 W (watts), When the light emitting element is an LED type, the power consumption is about 45 W (watt).
[0008]
In addition, as described above, the aviation obstacle light is disposed at a high place such as a steel tower or a building, but when the light emitting element is an LED type low intensity aviation obstacle light, the maximum diameter is φ210 mm. Since the height is as large as about 420 mm and the weight is as heavy as about 5 kg, it is difficult to carry to a high place and the workability of the mounting work is also poor. Therefore, there has been a great demand for reduction in size and weight.
[0009]
In order to reduce the power consumption to the extent that an independent power source such as a solar cell can be applied, and to reduce the size and weight, a high-brightness LED with high brightness is adopted for the light-emitting element, while ensuring the performance, while emitting light A method for reducing the number of elements can be considered. However, the method of reducing the number of light emitting elements in this way has a problem that other adverse effects are induced as follows.
[0010]
That is, the light emitting elements are designed and arranged in conformity with the standard so that the luminance and light distribution characteristics emitted as a whole aviation obstacle light are good, and are arranged in large numbers at a predetermined density. . For example, a plurality of light emitting elements are mounted in parallel on a substrate that is long in the vertical direction at a predetermined interval. A plurality of the light emitting element mounting substrates are arranged side by side at a predetermined interval on the side surface of the substantially cylindrical member, and thus the light source part is formed. In the case of a aviation obstacle light of the type in which a conventional light emitting element is an LED, for example, 22 LEDs are arranged on a vertically long substrate, and this substrate is the circumference of a substantially cylindrical support. It was arranged in 36 rows in the direction. Therefore, 792 LEDs were used.
[0011]
As described above, when the number of light emitting elements is significantly reduced in order to reduce power consumption, size, and weight with respect to the light source unit in which the light emitting elements are arranged at predetermined intervals, the distance between adjacent light emitting elements is reduced. Due to the increase in size, there has been a problem that the standard of light distribution characteristics cannot be satisfied, such as unevenness in the irradiation state depending on the direction. In particular, since the super-bright LED has a narrow light irradiation angle, the widening of the interval between the super-bright LEDs by reducing the number of arrangements greatly affects the deterioration of the light distribution characteristics. It was.
[0012]
An object of the present invention is to solve the above-mentioned problems of conventional aviation obstacle lights, that is, there is no adverse effect such as deterioration of light distribution characteristics even if the number of LEDs of the light source part is reduced, and low power consumption and small size. The purpose of this project is to provide aviation obstacle lights that are lighter and lighter, improve operability of aviation obstacle lights, reduce construction time, reduce construction costs, and reduce maintenance costs.
[0013]
[Means for Solving the Problems]
In order to solve the above-described problems, a light source unit formed by arranging a plurality of light emitting elements on the outer peripheral surface of a substantially cylindrical support, and a light source unit that is detachable from the light source unit and covers the light source unit A cover part, a base part having a structure in which the cover part can be attached and detached, and a structure that can be attached to a high-rise building, and a power supply part for turning on or blinking the light source part. In the aviation obstacle light, first, the cover portion is provided with a light distribution control unit that diffuses irradiation light emitted from the light emitting element to the outside in the horizontal direction, and secondly, the light distribution unit. The control unit has a groove portion formed along the axial direction of the cover portion, and a plurality of the groove portions are continuously provided at predetermined intervals over the entire inner peripheral side surface or outer peripheral side surface of the cover portion.

[0018]
Reference numeral 7 denotes a cover part for covering the light source part 1. The cover part 7 has a substantially pan-like shape and is formed of a transparent plastic or the like. A light distribution control unit 7a is disposed on the inner peripheral side surface of the cover unit 7. The light distribution control unit 7a will be described in detail later. The substrate 5 attached to the bottom of the light source unit 1 is provided with a mounting hole (not shown). A screw 8 or the like is inserted into the mounting hole and screwed into the screw hole 7c of the cover unit 7. By wearing, the light source unit 1 and the cover unit 7 can be integrated.
[0019]
Reference numeral 9 denotes a base portion, which is formed of a strong metal material such as stainless steel. The base part 9 is comprised from the upper part 9a which consists of a substantially pan-shaped shape, the middle part 9b which consists of the shape of a square pillar in which one part is hollow, and the lower part 9c which consists of a disk shape. A fitting portion 9 d is formed at the peripheral edge of the upper portion 9 a of the base portion 9, and the base portion 9 is covered with the fitting portion 7 d formed at the peripheral portion of the cover portion 7. Part 7 can be attached. And the ring-shaped attachment band 10 is formed in the outer peripheral surface of the part by which the base part 9 and the cover part 7 were fitted, and, thereby, the base part 9 and the cover part 7 are attached. Are firmly fixed.
[0020]
A power receiving terminal 12 for receiving power is provided in the hollow portion of the middle portion 9 b of the base portion 9. Reference numeral 11 denotes a lid, which is operated by removing the lid 11 from the base portion 9 when laying a power supply line.
[0021]
Furthermore, an A / D converter for converting the power supplied from the power receiving terminal 12 into a DC power source and a lightning arrester for protecting the aviation obstacle light from an excessive voltage such as a lightning surge are provided on the upper part 9a of the base unit 9. A mounted power supply unit 13 is provided.

[0022]
Furthermore, a through hole 14 for attaching the aviation obstacle light to the high-rise building is formed in the lower part 9c of the base 9, and the aviation obstacle light is attached to the high-rise building using screws or the like. It is fixed to.
[0023]
Next, the cover part 7 will be described in more detail. As described above, the light distribution control unit 7a is disposed on the inner peripheral side surface of the cover unit 7. The light distribution control unit 7a is formed by applying a special shape to the inner peripheral side surface of the cover unit 7. It is formed. That is, the groove portion 7 b is formed along the axial direction on the inner peripheral side surface of the cover portion 7, and a plurality of the groove portions 7 b are continuously provided at a predetermined interval over the entire circumference of the inner peripheral side surface of the cover portion 7. And the light distribution control part 7a is formed by chamfering about the uneven | corrugated | grooved part which arose by engraving the groove part 7b, and giving the surface of the inner peripheral side surface of the cover part 7 to a wave shape.
[0024]
Here, when the light distribution control unit 7a is not provided on the inner peripheral side surface of the cover unit 7, the irradiation light of the light emitting element 4 to which the ultra-bright LED is applied is 4.5 degrees in the horizontal direction. The light is diffused at a certain angle and irradiated to the outside through the cover portion 7. In addition, as described above, in the aviation obstacle light A, in order to reduce power consumption, the number of the light emitting elements 4 is reduced as much as possible, and the horizontal arrangement interval of the light emitting elements 4 is an angle of 13 degrees. It is getting bigger. Accordingly, unevenness occurs in irradiation depending on the direction, and the light distribution characteristic cannot be satisfied as an aircraft obstacle light.
[0025]
However, in the aviation obstacle light A of the present invention, since the light distribution control unit 7a having the above-described structure is provided in the cover unit 7, the following operation occurs, and the number of the light emitting elements 4 provided is small. In addition, there is no unevenness in irradiation, and it is possible to satisfy the light distribution characteristics as an aircraft obstacle light. That is, when the irradiation light emitted from a certain light emitting element 4 reaches the light distribution control unit 7a disposed on the inner peripheral side surface of the cover part 7, the unevenness formed by chamfering the groove part 7b. The portion causes the irradiation light to diffuse in the horizontal direction and passes through the cover portion 7. Since this action occurs for each of the irradiation light irradiated from the light emitting elements 4 arranged on the outer peripheral surface of the substantially cylindrical support body 2, an overlapping portion occurs in the irradiation light between the adjacent light emitting elements 4. As a result, uneven irradiation is prevented as a whole of the aviation obstacle light A, and the light distribution characteristics are satisfied.
[0026]
In this embodiment, the groove portion 7b is engraved with a width of about 1 mm, and a plurality of groove portions 7b are continuously provided at intervals of about 1.5 mm over the entire circumference of the inner peripheral side surface of the cover portion 7. About the width | variety and the space | interval of a groove part, as long as the light distribution characteristic is satisfied, it can change suitably. Further, the chamfering is preferably performed so that the entire convex portion 7e has a substantially semi-cylindrical shape, but this can be changed as appropriate as long as the light distribution characteristic is satisfied. Furthermore, the light distribution control unit 7a may be disposed on the outer peripheral side instead of the inner peripheral side of the cover unit 7.
[0027]
Since the aviation obstruction light of the present invention is configured as described above, the power consumption is about 5 to 10 W (watts), which is 5 minutes compared to the aviation obstruction light of the type in which the conventional light emitting element is an LED. It became possible to reduce it to about 1. As for the size, the maximum diameter is 190mm and the height is about 260mm. Compared to the type of aviation obstruction light in which the conventional light emitting element is LED, the height is reduced to about 2/3. I was able to plan. Further, the weight is about 2.5 kg, and the weight can be reduced to about one half as compared with the aviation obstacle light of the type in which the conventional light emitting element is LED.
[0028]
【The invention's effect】
Since this invention has the structure mentioned above regarding an aviation obstacle light, there can exist an effect in the description below.
[0029]
With regard to the light-emitting elements disposed in the light source section, the high-brightness LED is adopted so that the luminous intensity satisfies the standard, and the number of light-emitting elements is greatly reduced. Can be achieved. Therefore, maintenance costs can be reduced.
[0030]
In addition, since the aviation obstruction light has low power consumption characteristics, an independent power source such as a solar cell can be employed for power supply regardless of commercial power supply or electrostatic induction power supply means. Therefore, it is not necessary to lay wires and the like from a distance, and on the other hand, it is not necessary to insulate the overhead ground wire over a predetermined section, and it is not necessary to provide a control device that boosts and rectifies the induced voltage. It can be simplified. Therefore, the number of man-hours can be reduced and the construction cost can be reduced.
[0031]
Furthermore, since the number of light emitting elements arranged in the light source portion is small, the shape can be reduced to a maximum diameter of 190 mm and a height of about 260 mm, and the weight can be reduced to about 2.5 kg. . Therefore, when the aviation obstacle light is disposed at a high place such as a steel tower or a building, the burden of carrying it to the high place is reduced, and the workability of the installation work of the aviation obstacle light is improved.
[0032]
Furthermore, regarding the cover unit, a light distribution control unit that diffuses irradiation light irradiated from the light emitting element to the outside in the horizontal direction (in particular, the light distribution control unit has a predetermined length along the axial direction of the cover unit). Since a groove portion is engraved and a plurality of the groove portions are continuously provided at predetermined intervals along the entire inner peripheral side surface or outer peripheral side surface of the cover portion, the light emission is performed. Irradiation unevenness due to a decrease in the number of elements disposed can be eliminated, and the standard of light distribution characteristics can be satisfied.
[0033]
In other words, even if the number of LEDs in the light source section is reduced, there is no adverse effect such as deterioration of the light distribution characteristics, and a low-power consumption, compact, and lightweight aviation obstacle light is provided, and aviation obstacle light installation workability Improvement, reduction of construction time, reduction of construction cost, and maintenance cost.
