[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-luminance obstruction light.

[0002]

2. Description of the Related Art As a low-luminance obstruction light for informing an aircraft of a building that is an obstacle to the flight of the aircraft,
Conventionally, an incandescent lamp provided in a glove made of hard glass has been used.

[0003]

The life of an incandescent lamp is substantially determined by the heating time of the filament. Therefore, in the case of a low-luminance obstacle lamp using a heating bulb, a burning accident cannot be avoided, and replacement work is required each time.

However, in recent years, the shortage of workers has made it difficult to secure workers for replacing incandescent lamps for obstacle lights, especially obstacle lights installed in high places such as medium-wave antennas. It has become.

In order to solve such a problem, an obstacle light is formed by combining two light bulbs, and one of the light bulbs is always turned on. When the light bulb is burned out, the remaining light is automatically activated by the operation of a relay or the like. There is an obstacle light that turns on the light bulb.

[0006] Even with this type of obstacle light, although the urgency of replacing the bulb is reduced, there is no change in that the replacement must be performed promptly. There is also a problem that the occupied volume of the obstacle light increases.

[0007] The present invention has a longer life than an incandescent lamp, and even if some of the elements inside fail, the fault light is not completely turned off and the luminous intensity is only slightly reduced. It is an object of the present invention to propose a low-luminance obstruction lamp capable of performing the operation.

[0008]

The object of the present invention is to provide a plurality of substrates on which a plurality of light emitting diodes are arranged, a frame body capable of detachably fixing the substrates on side and top surfaces, and a method of lighting the light emitting diodes. Power supply, a connector for connecting the power supply and the light emitting diode on each board for each board, a base body to which the frame body is fixed, and a detachably fixed to the board so as to cover the frame body. The problem has been solved by a low-luminance obstruction light, which is made of a glove made of a light-transmitting material.

[0009]

[Operation] By using a plurality of light emitting diodes, the luminous intensity can be made equal to or higher than that of a case using an incandescent lamp.

Since the light emitting diode generates less heat, it consumes less power than an incandescent lamp at the same luminous intensity.

Since power is supplied to the light emitting diode for each substrate, even if one light emitting diode fails, it only affects the luminous intensity of the substrate on which the light emitting diode is mounted. That is, the obstacle light is not completely turned off, but only has a reduced luminous intensity as a whole. Therefore, the function as the obstacle light can be maintained.

When a light emitting diode fails, it is replaced on a substrate basis.

Substrates 4A, 4B, 4C, 4D, 4E, 4F
Is a rectangle, on which 50 light emitting diodes 5 are arranged, respectively. The substrate is mounted at four corners in the mounting holes 2 of the frame 1 using bolts 6 and spacers 7. It is also possible within the technical scope of the present invention to fix the substrate to the frame by inserting and guiding two opposing sides with a sliding guide without using bolts or the like.

On the back side of the board, there are provided connectors 8 for connection to a power supply for supplying power to the light emitting diodes of the board.

FIG. 5 is a front view of an example of the substrates 4G and 4H mounted on the upper surface of the frame 1, and FIG. 6 is a side view of the substrate of FIG.

The substrates 4G and 4H are trapezoidal, and 13 light emitting diodes 5 are arranged on each of them. The board is mounted in the mounting hole 2 of the frame 1 using bolts 6 and spacers 7.

On the back side of the board, there are provided connectors 8 for connecting to a power supply for supplying power to the light emitting diodes of the board.

FIG. 7 is a partially sectional elevation view of an example of the low-luminance obstacle light according to the present invention.

Six side surfaces 1 of a hexagonal column portion at the top of the frame 1
A, 1B, 1C, 1D, 1E, 1F
A, 4B, 4C, 4D, 4E, and 4F are attached, and substrates 4G and 4H are attached to the upper surface 1G of the hexagonal prism portion.

The lower part of the frame 1 is a power supply accommodating portion 9 in which a power supply circuit (not shown) is accommodated.

The frame 1 is fixed inside a pot-shaped base 12 via bolts 10 and spacers 11.

At the center of the lower surface on the outside of the substrate 12, an obstacle light mounting member 13 provided with a tube parallel screw is provided.

AC power is transmitted to the power supply circuit through a conductor 14 passing through a hole provided at the center of the obstacle light mounting member 13 and the bottom of the base, and DC power is supplied from the power supply circuit through a conductor 15 to each substrate. Sent to

The frame 1 and the substrate 4 fixed to the substrate 12
A glove 16 having a hat shape is detachably fixed to the substrate 1 via bolts 17 and nuts 18 so as to cover A, 4B, 4C, 4D, 4E, 4F, 4G, and 4H. That is, the frame 1, the substrate, the diode 5, and the power supply circuit are accommodated in a space surrounded by the base 12 and the globe 16. It is also possible to arrange a waterproofing seal between the glove 16 and the base 12 and around the conducting wire 14 within the technical scope of the present invention.

The globe 16 is made of a light-transmitting hard glass. Therefore, the light passes through the light globes 16 emitted from the large number of light emitting diodes 5 on the six side surfaces and the upper surface of the frame and propagates to the external space.

In order to reduce the direction dependency of the luminous intensity of the low-luminance obstruction lamp, it is preferable to provide a large number of irregularities on the inner surface or the outer surface of the globe 16.

FIG. 8 is an example of an electrical connection diagram for the low-luminance obstruction lamp of FIG. AC power is sent to the power supply circuit 20 via the conductor 14 and the fuse F.

The power supply circuit 20 is a bipolar DC power supply circuit composed of, for example, a switch regulator, and generates +24 VDC and -24 VDC. Note that the power supply circuit is not particularly limited to this circuit, and a unipolar DC power supply circuit or a simple single- or double-wave rectifier circuit can also be used.

The output of +24 VDC is applied to the substrates 4A and 4
C, 4E, 4F, the output of -24 volts
B, 4D, 4F, and 4H.

The conductor 15 connected to the output terminal of the DC power supply 20 is connected to the substrates 4A, 4B, 4C, 4D, 4E, 4F, 4
G and 4H respectively have connectors 8A, 8B, 8C, 8D,
They are linked via 8E, 8F, 8G, 8H.

Substrates 4A, 4B, 4C, 4D, 4E, 4F
In the above, one pack includes a circuit in which ten light emitting diodes and the protection resistor R are connected in series, and five packs are connected in parallel.

On the substrates 4G and 4H, six light emitting diodes are used.
Alternatively, a circuit in which seven protection resistors are connected in series is one pack, and two packs are connected in parallel.

When one light emitting diode fails, all the light emitting diodes in one pack to which the light emitting diode belongs are turned off. For example, if one light emitting diode (for example, the light emitting diode marked with X) in the ten light emitting diodes 5 at the top of FIG. 8 fails, all the ten light emitting diodes at the top are turned off.

However, the 40 light emitting diodes in the second to fifth stages on the substrate maintain the lighting state. That is, even if one light emitting diode on one substrate fails, the substrate is not completely turned off, but merely decreases in luminous intensity.

At this time, since the amount of light emitted from the other substrates does not change, the brightness of the low-luminance obstacle lamp as a whole is hardly affected.

If the light emitting diode of the low-luminance fault lamp fails, the entire board on which the failed light emitting diode is mounted is replaced during maintenance.

It is also within the technical scope of the present invention to provide a control circuit for blinking the light emitting diode or a current detector for detecting the current of each pack in order to know which pack has failed. Is possible.

[0041]

I) Even if one light emitting diode fails, it is not necessary to replace it immediately, so that the replacement cycle can be lengthened. That is, it can be maintenance-free. Therefore, it is easy to secure replacement personnel. ii) Compared to using an incandescent lamp, the power required to obtain the same luminous intensity is reduced to about 1/10.
