Japanese Laid-Open Patent Publication No. 06-302385

  By the way, in the above-described photoelectric automatic blinker, a failure may occur in the photoelectric automatic blinker or the illumination load, and the illumination load may not be lit even under the condition that the illumination load originally has to be lit. However, it is not easy to determine whether a failure has occurred in the luminaire or whether it has occurred in the photoelectric flasher simply by not lighting the illumination load. Unless it is possible to determine whether a failure has occurred in the photoelectric flasher or in the lighting load, it is very inconvenient when performing repair or replacement.

  The present invention has been made in view of the above-mentioned reasons, and the purpose of the present invention is that when a failure occurs in an illumination load or a photoelectric automatic flasher, either the photoelectric automatic flasher or the illumination load has a failure. It is an object of the present invention to provide a photoelectric automatic flasher that can easily know whether it has occurred.

  The invention according to claim 1 is inserted between a power source and a lighting load, and controls an output circuit unit that controls power supply from the power source to the lighting load, a control circuit unit that controls the output circuit unit, and ambient illumination An illuminance sensor for detecting the display, an indicator lamp circuit unit including an operation indicator lamp that is turned on when power is supplied from the output circuit unit to the illumination load, the output circuit unit, the control circuit unit, the illuminance sensor, and the indicator lamp. A housing for storing a circuit unit, and the control circuit unit controls the output circuit unit to supply power to the illumination load when the illuminance detected by the illuminance sensor is equal to or lower than a predetermined illuminance. The casing has a daylighting window that is formed of a light-transmitting material on a lower wall that faces downward when attached to a construction position and allows ambient light to enter the illuminance sensor, and the lower wall provided with the daylighting window The operation indicator light from the peripheral wall other than Wherein the extracting light.

  According to this configuration, the operation indicator lamp is lit when power is supplied from the output circuit unit to the lighting load, and the operation indicator lamp is not lit when power is not supplied to the lighting load. Therefore, if the lighting load does not light even though the operation indicator is lit, it can be determined that a failure has occurred in the lighting load, and the operation indicator lights up under the condition that the lighting load must be lit. If not, it can be determined that a failure has occurred in the photoelectric flasher. Therefore, it is possible to provide a photoelectric automatic flasher that can easily know whether a failure has occurred in a lighting fixture or a photoelectric automatic flasher.

  In addition, since a lighting window made of a translucent material is provided on the lower wall of the housing, it is possible to prevent direct light from a lighting load or other lighting fixtures from entering the lighting window. It is possible to prevent the surrounding illuminance detected in step 1 from becoming high and the illumination load from becoming unlit.

  Furthermore, since the light of the operation indicator light is taken out from a peripheral wall different from the lower wall of the housing provided with the daylighting window, the detection illuminance detected by the illuminance sensor becomes more than the actual illuminance by the light of the operation indicator light, It is prevented that the lighting load does not light up.

  According to a second aspect of the present invention, in the first aspect of the present invention, the housing includes an overload detection circuit unit that detects a current supplied from the output circuit unit to the lighting load. When the current detected by the overload detection circuit unit is greater than or equal to a predetermined threshold, the supply of power from the output circuit unit to the lighting load is stopped.

  According to this configuration, when the overload detection circuit unit detects the current supplied from the output circuit unit to the lighting load and the detected current is equal to or greater than the predetermined threshold, the control circuit unit detects that the lighting load is overloaded. And the output circuit unit is controlled to stop the supply of power from the output circuit unit to the lighting load. Therefore, even if an overloaded lighting load is installed by mistake after replacing the lighting load by repair, etc., the power supply to the lighting load is not continued, and the safety of the lighting load and the photoelectric flasher Is secured.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein a current detection circuit unit that detects a current supplied from the output circuit unit to the lighting load, and a current detected by the current detection circuit unit A non-operation indicator lamp that is turned on when the value is equal to or less than a predetermined threshold value is provided in the casing.

  According to this configuration, it is possible to confirm from the outside that sufficient power for lighting the lighting load is not supplied from the output circuit unit to the lighting load by turning on the non-operation indicator lamp. In addition to the operation of turning on and off, it is possible to confirm the presence or absence of power supply to the lighting load.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the housing has a human sensor for detecting the presence or absence of a person, and the illuminance detected by the illuminance sensor is The case has a dimming circuit unit in the housing for reducing power supplied from the output circuit unit to the illumination load when the human sensor detects a presence of a human being below a predetermined illuminance. Features.

  According to this configuration, when the illuminance detected by the illuminance sensor is equal to or less than a predetermined illuminance and the human sensor does not sense the presence of a person, the dimming circuit unit controls the output circuit unit to Since the electric power supplied to the lighting load is reduced, it is possible to reduce the electric power used compared to the lighting of the lighting load when a person is sensed.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the casing has a timing circuit unit for measuring time, and the illuminance detected by the illuminance sensor is predetermined. When the time is less than illuminance and the measured time reaches a predetermined time, when the presence sensor does not detect the presence of a person, power is not supplied to the lighting load, and the presence sensor detects the presence of the person. In this case, power is supplied to the illumination load.

  According to this configuration, when the illuminance detected by the illuminance sensor is equal to or less than the predetermined illuminance, and when the lighting load is turned on by supplying power, the illuminance sensor Even if the detected illuminance is less than or equal to the predetermined illuminance, only when the presence sensor detects the presence of a person, power is supplied from the output circuit unit to the illumination load and the illumination load is turned on. Therefore, the lighting load can be used as a security light.

  A sixth aspect of the invention is characterized in that, in the invention of any one of the first to fifth aspects, the daylighting window and the sensor window are formed of a translucent opaque material.

  According to this configuration, since the daylighting window and the sensor window are formed of a translucent opaque material, it is impossible to confirm the presence of the illuminance sensor and the human sensor from the outside. Therefore, it is possible to conceal the existence of the illuminance sensor and the human sensor from a suspicious person or the like.

  In the case where the lighting load is not turned on under the condition that the lighting load must be turned on, that is, when a failure occurs in either the photoelectric automatic blinker or the lighting load, the photoelectric automatic blinker or This has the effect of facilitating the determination of which of the lighting loads has failed, thereby facilitating the repair or replacement of the photoelectric automatic flasher or the lighting load.

  The photoelectric automatic flashing device in the following embodiments is configured so that a wall substantially perpendicular to the ground, such as an outer wall surface of a building, can be attached as a construction surface.

In addition, the horizontal and horizontal direction parallel to the construction surface is the left and right direction, the vertical direction to the ground is the up and down direction, the construction side of the photoelectric flasher is the rear, the opposite side is the front, the configuration of the photoelectric flasher explain.
(Embodiment 1)
First, the configuration of the photoelectric automatic flasher SW of the present embodiment will be described with reference to FIG.

  The photoelectric flasher SW includes a rear wall (not shown) attached to a construction surface (not shown), a lateral wall 2 that is connected substantially perpendicularly to the rear wall and encloses the left and right sides, a curved wall 3 that encloses the upper side and the front side, and a lower side. It is formed by a housing 1 made up of a lower wall 4 that surrounds. The lower wall 4 of the housing 1 faces downward, that is, the ground side in a state where the photoelectric flasher SW is attached to the construction surface. The lower wall 4 is formed with a daylighting window 5 made of a translucent opaque material for taking in the light around the photoelectric automatic flasher SW into the housing 1, and the rear side of the daylighting window 5. Is provided with an illuminance sensor 9 for detecting light around the photoelectric automatic flasher SW taken in from the daylighting window 5. The curved wall 3 is provided with an operation indicator lamp window 8 made of a translucent material for confirming whether or not an operation indicator lamp (not shown) is lit from the outside.

  Although FIG. 1 shows an example in which a sensor window 6 corresponding to the human sensor 7 is provided on the lower wall 4 of the housing 1, these configurations will be described in other embodiments.

  As shown in FIG. 2, the housing 1 includes an output circuit unit 11 that turns on / off power supplied from the power source E to the lighting load 14, a power supply circuit unit 10 that supplies power to the control circuit unit 12, and an output A control circuit unit 12 that controls the on / off operation of the circuit unit 11, an indicator lamp circuit unit 15 that includes an operation indicator lamp (not shown) that is turned on when power is supplied to the illumination load 14, and a photoelectric automatic flasher SW around An illuminance sensor 9 for detecting illuminance is accommodated.

  Next, the basic operation of the photoelectric flasher SW and the operation of the operation indicator lamp (not shown) will be described with reference to FIG.

  First, the power supply circuit unit 10 generates a predetermined DC voltage from a power supply E such as a commercial power supply, and supplies power to the control circuit unit 12. The control circuit unit 12 is driven by the supplied power. The illuminance sensor 9 detects the illuminance around the photoelectric automatic flasher SW by detecting light that has entered through the daylighting window 5. When the illuminance detected by the illuminance sensor 9 is less than or equal to the predetermined illuminance, the control circuit unit 12 controls the on / off operation of the output circuit unit 11 so that power is supplied to the illumination load 14. It is desirable to use a semiconductor switch made of triac or MOSFET for the output circuit unit 11. In this configuration, it is possible to control the power supplied to the illumination load 14 by controlling the phase angle at which the semiconductor switch is turned on and off by the control circuit unit 12. Next, the indicator light circuit unit 15 supplies a part of the electric power supplied to the illumination load 14 to the operation indicator lamp, and turns on the operation indicator lamp. For example, when an LED is used as the operation indicator lamp, the LED and the resistor are connected to the output circuit unit 11 in parallel with the illumination load 14. Thereby, when electric power is supplied to the illumination load 14, the operation indicator lamp is turned on, and when no electric power is supplied, the operation indicator lamp is not turned on. Therefore, whether or not power is being supplied to the lighting load 14 can be confirmed based on whether or not the operation indicator is lit. Therefore, when a failure occurs in the photoelectric automatic flasher SW or the lighting load 14, the photoelectric type It is possible to easily know whether the automatic flasher SW or the lighting load 14 has failed.

(Embodiment 2)
As shown in FIG. 3, the photoelectric automatic flasher SW of this embodiment is different from the photoelectric automatic flasher SW of Embodiment 1 in that an overload detection circuit unit 16 is provided.

  With reference to FIG. 3, the operation of the overload detection, the non-operation indicator lamp (not shown) and the abnormal lamp (not shown) of the photoelectric automatic flasher SW of the present embodiment will be described. In the configuration of the present embodiment, a non-operating indicator lamp window (not shown) formed of a translucent material for confirming whether or not the non-operating indicator lamp is lit on the curved wall 3 in the housing 1 from the outside; An abnormal lamp window (not shown) made of a translucent material for confirming whether or not the abnormal lamp is lit from the outside is added.

  When the illuminance detected by the illuminance sensor 9 is less than or equal to a predetermined value, the control circuit unit 12 controls the on / off operation of the output circuit unit 11 to supply power to the illumination load 14 as described above. At this time, the overload detection circuit unit 16 detects the current supplied from the output circuit unit 11 to the illumination load 14. When the detected current is equal to or greater than a predetermined threshold, the control circuit unit 12 determines that the lighting load 14 is overloaded, and controls the on / off operation of the output circuit unit 11 to supply power to the lighting load 14. To stop. In this case, the control circuit unit 12 performs control to turn on the abnormal lamp.

  Therefore, even when the illumination load 14 which is an overload is attached to the photoelectric automatic flasher SW, the power of the lighting load 14 and the photoelectric automatic flasher SW is kept safe by not supplying power to the lighting load 14 continuously. The user can easily know that the overload illumination load 14 is attached to the photoelectric flasher SW by turning on the abnormal lamp.

  On the other hand, when the current supplied from the output circuit unit 11 detected by the load detection circuit unit 16 also serving as the current detection circuit unit to the lighting load 14 is equal to or less than a predetermined threshold and is less than the current for lighting the lighting load 14 In this case, the control circuit unit 12 performs control to turn on the non-operation indicator lamp. Therefore, it can be easily known that the lighting load 14 is not supplied with sufficient power to turn on the lighting load 14 by turning on the non-operation indicator lamp.

  In the present embodiment, it is displayed that the illumination load 14 is overloaded by the lighting of the abnormal lamp. However, the present invention is not limited to this. For example, the operation display lamp has two types of emission colors and one color is displayed. May be used for the operation indicator lamp and the other color for the abnormal lamp.

  Also, instead of the non-operation indicator lamp that indicates that the illumination load 14 is not lit, the operation indicator lamp has two types of light emission colors, one color is used for the operation indicator lamp, and the other color is not. It is good also as a structure used for an operation indicator lamp. Further, the operation state lamp, the abnormal lamp, and the non-operation lamp may be used in combination with three kinds of lighting states.

  Other configurations are the same as those of the first embodiment.

(Embodiment 3)
As shown in FIG. 1, the photoelectric automatic flasher SW of the present embodiment protrudes outward from the lower wall 4 of the housing 1 and has a hemispherical shape and a translucent opaque material. The sensor window 6 is formed, the human sensor 7 is disposed on the rear side of the sensor window 6, the point where the dimming circuit unit 13 is provided as shown in FIG. 4, and the timing circuit unit (Not shown) is different from the photoelectric automatic flasher SW of the first embodiment.

  The human detection sensor 7 is configured to be rotatable about a substantially vertical direction in the sensor window 6, and is configured to be able to change the detection area of the human body and to detect a wide range of people. ing.

  The operation of this embodiment will be described with reference to FIG.

  As described above, when the illuminance detected by the illuminance sensor 9 is greater than or equal to the predetermined illuminance, the control circuit unit 12 controls the on / off operation of the output circuit unit 11 so as not to supply power to the illumination load 14. When the illuminance detected in 9 is less than or equal to the predetermined illuminance, the control circuit unit 12 controls the on / off operation of the output circuit unit 11 to supply power to the illumination load 14. When the illuminance detected by the illuminance sensor 9 is less than or equal to a predetermined illuminance and power is supplied to the illumination load 14, the dimming circuit unit 13 is further provided with an output circuit unit by sensing the presence or absence of a person by the human sensor 7. 11 on / off operation is controlled. More specifically, when the presence of a person is detected by the human sensor 7, the supply of power to the lighting load 14 is maintained, and when the presence of a person is not detected, the dimming circuit unit 13 outputs The on / off operation of the circuit unit 11 is controlled to reduce the power supplied to the lighting load 14. As described above, when a semiconductor switch such as a triac or MOSFET is used as the output circuit unit 11, the dimming circuit unit 13 supplies the lighting load 14 by controlling the phase angle at which the triac or MOSFET is turned on and off. To reduce power.

  When the illuminance detected by the illuminance sensor 9 is less than or equal to a predetermined illuminance by the control of the output circuit unit 11 of the dimming circuit unit 13 and the presence of a person is not detected around the photoelectric automatic flasher SW, Since the illumination load 14 is turned on with less power than usual, wasteful consumption of power can be suppressed.

  The time measuring circuit measures the elapsed time from when the illuminance detected by the illuminance sensor 9 becomes equal to or less than a predetermined illuminance. Since the illuminance is less than or equal to the predetermined illuminance, power is supplied from the output circuit unit 11 to the illumination load 14, and the illumination load 14 is lit. In this case, when the time counted by the timing circuit unit satisfies a predetermined time, the control circuit unit 12 does not control the on / off operation of the output circuit unit 11 based on the fact that the illuminance is less than the predetermined illuminance, and the illuminance is predetermined. The on / off operation of the output circuit 11 is controlled based on whether it is greater than the illuminance or the presence / absence of a person as detected by the human sensor 7. More specifically, the control circuit unit 12 determines that a predetermined time has elapsed since the illuminance is less than or equal to the predetermined illuminance based on the time measured by the time measuring circuit unit, and the human sensor 7 detects the photoelectric automatic flasher SW. When it is determined that there is no person in the surroundings, the control circuit unit 12 controls the on / off operation of the output circuit unit 11 to supply power to the lighting load 14 even when the illuminance is equal to or less than the predetermined illuminance. To stop. When it is determined by the human sensor 7 that there is a person around the photoelectric automatic flasher SW, the on / off operation of the output circuit unit 11 is controlled to supply power to the illumination load 14.

  Therefore, when the time from when the illuminance measured by the timing circuit unit falls below the predetermined illuminance satisfies the predetermined time, the illumination load 14 is turned on only when there is a person around the photoelectric flasher SW. In addition to suppressing wasteful power consumption, it will function as a security light. After that, when the illuminance becomes equal to or higher than the predetermined illuminance, the time counting in the timing circuit unit is stopped, and the control circuit unit 12 controls the supply of power to the illumination load 14 again by the detected illuminance in the illuminance sensor 9.

  The control circuit unit 12 performs the above-described control when the elapsed time from when the illuminance detected by the illuminance sensor 9 becomes equal to or less than a predetermined value satisfies the predetermined time. However, the control circuit unit 12 is not limited to this. A configuration may be adopted in which the above-described control is performed when a predetermined time elapses due to timing in the unit.
