2. Description of the Related Art An illumination lamp such as a street lighting or a crime prevention light which is turned on only at night includes a normal lamp, a lighting means such as a ballast for supplying a lighting current to the lamp, and a blinking means for controlling blinking of the lamp. . Then, the blinking means detects ambient brightness and the like, and gives a desired lighting or extinguishing instruction of the lamp.

By the way, in such an illuminating lamp which is turned on only at night, the maintenance and management thereof is extremely difficult. That is, since the lamp is turned off by the automatic flashing means in the daytime, a patrol inspection is performed at night when the lamp must be turned on, and after confirming the illuminating lamp in a faulty state, the replacement work of the daytime lamp etc. It had to be done, and the work was troublesome twice. On the other hand, when the work is completed by one round of work, it is necessary to confirm the presence or absence of lighting of the lamp by forcibly lighting the automatic blinking means during the daytime, for example.

[0004]

However, when the automatic blinking means is forcibly turned on as described above, it is necessary to individually operate the automatic blinking means for each illuminating lamp. A tower car or the like was required, and the work was complicated and the influence on the surroundings due to traffic restrictions was extremely large. The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide an astigmatism display device for an illumination lamp capable of displaying an astigmatism abnormality of a lamp or the like in an extinguished environment.

[0005]

In order to achieve the above-mentioned object, an illumination lamp defect display device according to the present invention is applied to a lighting device for lighting or extinguishing a lamp based on an instruction of a blinker, and a lamp defect A detection unit, a lighting failure determination unit, and a lighting failure display unit are provided. The lamp fault detection means,
Detects the imperfect condition of the lamp. The lighting failure determination means determines a lighting failure when the lamp fault detection means detects that the lamp is in the faulty state during the time period when the lamp should be turned on.

The defective lighting display means includes a defective display portion for visually confirming the defective state when the lamp is defective, a power application portion for operating the defective display portion based on an instruction from the defective lighting determination means, and the defective portion. And a holding unit that holds the defect display position of the display unit, and continuously displays the lighting failure. Further, the defect display device for an illumination lamp according to claim 2 of the present invention,
The lighting failure display means is formed in a plate shape and is composed of a magnet having an S pole at one end and an N pole at the other end of the plate shape, and is rotatably supported about the boundary line between the two poles. A member, a core member made of a magnetic material whose tip is arranged close to both poles of the defective display rotating member, and the core member, and the current is conducted based on the instruction of the lighting failure determination means. And a coil member.

According to a third aspect of the present invention, there is provided an illumination lamp defect display device in which the lighting failure display means is wound in a hollow cylindrical shape, and a current based on an instruction from the lighting failure determination means is conducted. A coil member and a magnet having an S pole on one opening side of the cylinder and an N pole on the other opening side of the coil member, and the coil center is formed by conducting current to the coil member. A defect display movable member that operates along an axis, and a holding member that holds the defect display movable member in an operating position,
It is characterized by having.

[0008]

In the illuminating lamp astigmatism display device according to the present invention, the lamp astigmatism detecting means detects the extinguished state of the lamp, and when the lamp is not lit in the lamp lit time zone, A defect display is performed assuming that there is some defect. When a defective display rotating member is used as the defective display, the defective display is performed depending on the rotational position state of the defective display rotating member.

As described above, the defective display rotating member is composed of a plate-shaped magnet, and the tips of the core members, which are magnetic bodies, are arranged at the positions near the S pole and N pole, respectively. The coil member is wound. Then, based on the determination result of the lighting failure determination means, a current is conducted to the coil member in the opposite direction for good lighting and bad lighting.

When a current is conducted to the coil member, both ends of the core member are excited to the S pole and the N pole, respectively, and the directions of the poles are switched by reversing the conducting directions of the current. The S pole side of the defective display rotating member is attached to the N-pole of the defective display rotating member at the tip excited by the N pole of the core member.
Since the pole side is attracted to the tips of the core members excited by the S poles respectively, if the poles at both tips of the core member are reversed by changing the current direction, the defective display rotating member rotatably supported. Is reversed.

Therefore, if the current is conducted to the coil member in the current direction based on the judgment result of the lighting failure judgment means, the judgment result is reflected in the rotational position of the defect display rotating member. Further, the rotational position of the defective display rotating member is attracted to the tip of the core member by the magnetic force of the defective display rotating member itself until the current in the opposite direction is conducted, even if the current conduction is interrupted. The state will be maintained.

For this reason, if the front and back surfaces of the defective display rotating member can be identified, it is possible to confirm the defective lighting outside the lamp lighting period and even if the current conduction is interrupted due to a power failure or the like, Since the rotation position state of the defect display rotating member is maintained, it is possible to continuously display the lighting defect. Further, as the defect display, a defect display movable member may be used and displayed according to its operating position.

The defective display movable member utilizes a so-called latch type solenoid, and the defective display movable member composed of a magnet is arranged in a cylinder of a coil member wound in a hollow cylindrical shape. Then, when a current is conducted to the coil member, a magnetic field is generated in the hollow portion of the coil member, and the position of the defective display movable member is moved by the action of the magnetic force. Therefore, when a lighting failure is detected in the lamp lighting time zone, a current is conducted to the coil member to operate the defective display movable member, and the operating position is magnetically or mechanically held, so that the lamp lighting time is reduced. Even in areas other than the band, it is possible to continuously display the lighting failure by externally identifying the operating state.

FIG. 2 shows a more specific structure of the illumination section 12 of the street light 10 shown in FIG. 1, and FIG.
3B is a vertical cross-sectional view, and FIG. 3B is a view as seen from the direction of arrow I of the illumination unit 12 (direction of the column installation end). As is clear from the figure, the lighting unit 12 includes a housing 20, a discharge lamp 22 as a lamp arranged in the housing 20,
Discharge lamp ballast 2 for stably lighting the discharge lamp 22
4 and a power factor improving capacitor 26 connected to the primary coil of the discharge lamp ballast 24.

The lighting current supplied through the pillar 14 is supplied to the discharge lamp ballast 24 and the power factor improving capacitor 2
It is supplied to the discharge lamp 22 via 6 and the discharge lamp 22 is turned on as desired. An automatic blinker 28 is installed in the vicinity of the discharge lamp ballast 24, and the light detection unit 18 of the automatic blinker 28 is exposed from below the housing 20. Then, in the state where the light detection unit 18 detects a predetermined light amount or more, it is determined that it is daytime, and the discharge lamp 22
Is turned off, and when the amount of light received by the light detection unit 18 is less than or equal to a predetermined amount, it is determined that it is nighttime, and the lighting control of the discharge lamp 22 is performed.

A characteristic of the present invention is that the discharge lamp 2
When the lighting disabled state is caused by the abnormality of the lamp or the blinker despite that 2 should be turned on at night, the lighting disabled state can be confirmed in the daytime. Therefore, in this embodiment, As shown in FIG. 3, a fault display device 30 including a lamp fault detection means and a lighting failure determination means and a magnetic reversal element 32 as a lighting failure display means are provided. Then, in the defect display device 30 shown in FIG. 7A, the drive current is supplied from the power source 34, and the blinker 28 and the ballast 2 are provided.
Voltage detection and current detection are performed from 4 (on the primary coil side of the ballast).

The defect display device 30 is shown in FIG.
As shown in, between the blinker 28 and the ballast 24 (ballast 2
It is also possible to detect the voltage from the primary coil side (4) and to detect the current or voltage from between the ballast 24 and the discharge lamp 22 (the secondary coil side of the ballast 24). The current transformer 36 is used as the detection unit of the defect detection circuit, as shown in FIG. 4, for example.

The current transformer 36 is installed between the primary winding 24a of the ballast 24 and the power factor improving capacitor 26, as shown in FIG. The primary-side current obtained by removing the current of the capacitor 26 is detected. Then, the difference between the conduction current when the discharge lamp 22 is lit and the conduction current when the discharge lamp 22 is not lit is detected by the astigmatism detection circuit 37.
The astigmatism state of 2 is detected. Further, the signal of the astigmatism state is input to the determination circuit 38, and the pulse signal based on the determination result of the signal in the time period when the lamp should be turned on is input to the magnetic reversal element 32. The lamp operating time is
It is preferable to connect a timer that sets the time zone and the like to the determination circuit and make a determination based on a signal from the timer.

As shown in FIG. 5, the current transformer 36 is connected in series between the power source 34 and the power factor improving capacitor 26, and a regular temporary current including the current of the power factor improving capacitor 26 is applied. It is also possible to detect by the current transformer 36. Further, it is possible to provide a phase difference detection circuit 40 as shown in FIG. 6 without using the current transformer 36 in the astigmatism detection circuit 37.

In the phase difference detecting circuit 40, the primary current when the discharge lamp 22 is normally turned on is delayed from the reference phase of the power source as shown in FIG. 7A as shown in FIG. 7B. However, when the discharge lamp 22 cannot be lit, the current phase shifts to the advanced state as shown in FIG. Therefore, by detecting this phase difference, the discharge lamp 22
It is possible to properly judge the disadvantages of. Moreover, according to the circuit shown in FIG. 6, since the phase difference is detected, for example, when the current difference between the primary current when the discharge lamp 22 is normally lit and the no-load primary current when the discharge lamp 22 is faulty is small. Moreover, it is possible to always make an appropriate defect determination.

Next, the magnetic reversal element 32 used in this embodiment will be described. FIG. 8 shows a configuration explanatory view of the magnetic reversal element 32. The magnetic reversal element 32 shown in the figure has a magnetic reversal display plate 48 as a defect display section (defective display rotation member), a core 42 and coils 44, 46 as power application sections. The core 42 is formed in an inverted C shape, and a set coil 44 and a reset coil 46 are wound around the core 42 so that currents flow in opposite directions. Further, the core 42
A magnetic reversal display plate 48 is arranged in the opening of the display device in the vicinity of both ends of the inverted C type, and the N pole is located above the S pole and below the S pole in the figure. It is rotatable around the center.

The set pulse is applied to the set coil 44.
Alternatively, when the reset pulse is conducted to the reset coil 46, both ends of the core 42 are excited to the S pole and the N pole. Further, the poles at both ends of the core 42 are switched when the set pulse is conducted to the set coil 44 and when the reset pulse is conducted to the reset coil 46.

Since the different poles of the display plate 48 are attracted to the poles at both ends of the excited core 42, the set pulse is conducted to the set coil 44 and the reset pulse is reset coil. The surface of the display plate 48 is positioned 180 degrees different from that when it is electrically connected to 46. That is, when a set pulse is conducted to the set coil 44 as shown in FIG. 8A, an N pole is formed above the core 42 and an S pole is formed below the core 42. For example, the display plate 48 shown in FIG. The surface is in a position facing the outside.

On the other hand, when the reset pulse is conducted to the reset coil 46 as shown in FIG. 7B, the upper side of the core 42 becomes the S pole and the lower side becomes the N pole, contrary to FIG. Be excited. Therefore, the display plate 48 rotates 180 degrees about the rotation axis 50, and the back surface of the display plate 48 shown in FIG. As described above, when the magnetic reversal element 32 according to the present embodiment is used, the reversal display plate 48 is rotated by the input of the set pulse or the reset pulse. The lighting failure can be displayed depending on whether the surface of the is facing.

Further, in the position position rotated by the conduction of the set pulse to the set coil 44 or the reset coil 46, the tip of the core 42 acts as a holding portion even after the conduction is released, and the display plate 48 itself. The rotational position of the core 42 is maintained by the magnetic force of the core 42.
Therefore, even if the current supply to the astigmatism display device is cut off in the rotational position state where the display plate 48 displays the lighting failure, the status of the lighting failure display is maintained and the lighting is performed during the lamp lighting time zone. The defect display can be made more reliable.

As described above, according to the defect display device according to the present embodiment, a defect display is made due to, for example, a night lighting defect, but a power failure occurs before the daytime patrol, and the electrical holding state is reset. In such a case, the defect display can be continued, and the accuracy of the defect display can be significantly improved as compared with the instruction by the defect display lamp or the like. In addition to the magnetic reversal element, it is also preferable to use a latch solenoid as a lighting failure display means.

9A and 9B are explanatory views of the structure of the magnetic latch solenoid 52. FIG. 9A shows a good lighting state, and FIG. 9B shows a poor lighting state. The magnetic latch solenoid 52 shown in the figure has a movable portion 56 as a defect display portion (defect display movable member), a coil 54 as a power application portion, and a holding portion 58.

The coil 54 is wound in a hollow cylindrical shape, a movable part 56 is arranged in the cylinder of the coil 54, and a ring shape made of a magnetic material is provided near both sides of the coil opening of the coil 54. The holding portions 58a and 58b formed in the above are arranged. Further, the movable portion 56 is formed with an S pole on the upper side and an N pole on the lower side in the drawing. FIG. 7A shows a state in which the determination circuit 38 has determined that the lighting is good, and no current is conducted to the coil 54. In this state, the movable portion 56 is held by the holding portion 58a arranged above the coil 54 by its magnetic force.

When the determination circuit 38 determines that the lighting is defective, a current is conducted to the coil 54, and the upper side of the coil 54 is excited to the N pole and the lower side is excited to the S pole. Therefore, the movable portion 56 is attracted downward and moves as shown in FIG. Further, as shown in FIG. 7B, the movable portion 56 is separated from the holding portion 58a and is held by the holding portion 58b arranged below the coil 54 by the magnetic force of the movable portion 56, so that the coil 54 is held.
This state is maintained even if the current conduction to is cut off.

Therefore, in order to easily confirm the operating state of the movable portion 56, for example, the display pin 60 is fixed to the lower surface of the movable portion 56, the display pin 60 is pulled in in the good lighting state, and in the poor lighting state. The protrusion of the display pin 60 makes it possible to display the lighting failure during a period other than the lamp lighting time period. Although the holding portion of the movable portion 56 is of the magnetic latch type in FIG. 9, it may be of the mechanical latch type as shown in FIG.

That is, a convex portion is provided above the movable portion 156,
A holding portion 158 having two concave portions into which the convex portions fit.
Is placed above the coil 154. And the same figure (A)
As shown in FIGS. 2B and 2B, at each position of the movable portion 156, the convex portion of the movable portion 156 fits into one of the concave portions formed in the holding portion 158, whereby the movable portion 156.
The operating position of is maintained. As described above, according to the defect display device according to the present embodiment, it is possible to continuously display the lighting failure of the street light regardless of interruption of the current supply such as a power failure. It is possible to confirm that the discharge lamp 22 cannot be turned on during the patrol, and the maintenance work can be greatly simplified.

[0033]

As described above, according to the astigmatism display device for an illuminating lamp of the present invention, by continuously displaying the astigmatism state of the lamp during the lamp lighting time period, the lamp failure is not displayed during the lamp lighting time period. It is possible to check the dot state.
