Description

  The present invention relates to a technique for inspecting a lighting device, and more particularly to a technique for starting an inspection operation.

  The lighting device is an essential means for supporting human activities by illuminating an internal space that is blocked or restricted by outside light in a building or underground. In particular, it is an important facility for providing lighting in the event of an emergency such as a disaster to assist evacuation to a safe place and to smoothly proceed with a recovery operation such as a failure.

  For this reason, many lighting devices have a function that enables lighting even during a power failure. In such an apparatus, it is usually checked whether or not the lighting function at the time of a power failure can be normally activated in preparation for a power failure. Here, the lighting device is usually installed at a high position, and it is difficult for the inspector to directly operate by hand or in a state where it cannot be operated.

  The start of the inspection operation in this state is based on a method of pulling the string attached to the inspection switch installed in the lighting device and turning on the switch as disclosed in, for example, Patent Document 1 and Patent Document 2. It is well known. In this case, a hole is formed in the outer frame of the device for taking out the string from the device.

  In addition, as disclosed in Patent Document 3, for example, a method of starting an inspection operation using a remote control transmitter instead of using an inspection switch to which a string is attached has been proposed.

JP 2011-113658 A JP 2011-090926 A JP 2009-187740 A

  However, the string attached to the inspection switch needs to hang down to a range that can be reached by human hands. In addition, in a working space such as an underground passage including a tunnel (a tunnel that accommodates communication cables, power transmission cables, gas pipes, etc. and allows a person to enter for work), the humidity is generally very high. For this reason, there is a concern that moisture enters the inside of the device through the hole for passing the string attached to the inspection switch, and the device in the device is deteriorated by causing deterioration of the circuit in the device.

  Further, in the method of using the remote control transmitter for starting the inspection operation, the troublesomeness that the remote control transmitter has to be carried around, taken out and operated at the time of inspection cannot be wiped out.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail, referring an accompanying drawing. In the drawings, the same elements are denoted by the same reference numerals. In addition, the dimensional ratios in the components in the drawings and between the components are arbitrary for easy viewing of the drawings.

  FIG. 1 is a plan view (FIG. 1A), a front view (FIG. 1B), and a side view (FIGS. 1C and 1D) showing an embodiment of a lighting device according to the present invention. . In the following drawings, an xyz coordinate system serving as an index of the orientation of the apparatus or the like is shown as appropriate.

  The illuminating device 1 of this embodiment is an apparatus for illuminating, for example, a passage / work space inside a cave. Here, the cave means a tunnel that accommodates communication cables, power transmission cables, gas pipes, etc., and is large enough for a person to enter for work. The lighting device 1 includes a storage battery 24 so that the inside of the cave can be illuminated even during a power failure, and performs illumination using the power of the storage battery 24 during a power failure.

  According to FIGS. 1 (A) to 1 (C), the illumination device 1 emits illumination light from the illumination unit 22 installed on the base plate 11 through the illumination window 122 provided on the cover 12 that covers the illumination unit 22. Radiate. The lighting unit 22 can be supplied with both commercial power input via the power line 4 and output power from the storage battery 24 installed in the lighting device 1.

  The base plate 11 is made of, for example, a metal such as stainless steel, and the surface thereof may be subjected to anticorrosion treatment such as painting. On the base plate 11, as shown later with reference to FIG. 3, circuit devices and components for illumination including the illumination unit 22 are installed. The cover 12 is made by molding a mold resin such as polycarbonate, for example, and does not allow light such as painting to pass through portions other than the illumination window 122, the display window 123, and the inspection window 121 (FIG. 1D). Processing has been applied.

  Here, in the illuminating device 1, it can be checked whether the illumination function at the time of a power failure can be started normally. Specifically, the inspection mode can be activated separately from the normal mode in which normal illumination is performed. The inspection window 121 provided in the cover 12 is an optical opening having translucency (transmission) for starting the inspection mode. As will be described in detail later, the inspector can easily activate the inspection mode by holding his / her hand over the light emitted from the inspection window 121 (inspection light).

  In the present embodiment, the inspection window 121 is provided on a side surface (which is the yz plane) opposite to the cable gland 13 in order to avoid interference with illumination light as much as possible. However, it is naturally possible to provide the lighting device 1 at another position.

  The display window 123 is an optical opening for displaying the operation state (operation mode) of the lighting device 1. From the display window 123, the display lamp 26 (FIG. 3) can be visually observed, and the power supply state, power failure state, and inspection state can be confirmed from the lighting state.

  In general, the space in the cave is very humid, for example, the humidity is often about 100%. In order to prevent moisture, the base plate 11 has a plurality of screw holes for attaching the cover 12, and the cover 12 is screwed with screws inserted into the screw holes from the top side of the base plate 11. doing. Thereby, the space between the base plate 11 and the cover 12 is sealed, and the waterproofness of the entire apparatus is ensured. In addition, it is also preferable that the base plate 11 is provided with a mounting hole for installing the lighting device 1 itself, for example, on a ceiling or a side wall of a cave.

  Further, the power line 4 extends to the inside of the lighting device 1 via the cable gland 13 and supplies commercial power to the lighting device 1 while ensuring the waterproofness of the device. Thus, the illuminating device 1 is hermetically sealed and has high waterproofness. In addition, the string for starting the inspection mode which is generally seen is not hanged out in the illuminating device 1. FIG. Therefore, it does not have a hole for taking such a string out of the apparatus. Further, it is not necessary to open the cover 12 and operate the inside of the apparatus at the time of inspection. As a result, it is possible to maintain the sealing property and waterproofness of the device in a high state.

  FIG. 2 is a schematic diagram for explaining the state in which the lighting device 1 is installed in the cave and the operation for starting the inspection mode.

  According to FIG. 2 (A), the illuminating device 1 is installed in the ceiling part of the passage of a cave. Here, the longitudinal direction (x-axis direction) of the lighting device 1 is orthogonal to the direction of the passage (direction perpendicular to the paper surface). When the apparatus is installed in this way, the inspection light T, which is the emitted light from the inspection window 121, is emitted obliquely downward toward the side wall surface of the cave. At this time, an area indicated by a dashed ellipse in FIG. 2A is an inspection activation area where inspection activation is possible.

  According to FIG. 2B, the inspector activates the inspection mode by putting his / her palm in the inspection activation area and holding it over the inspection light T. In this case, the inspection light T reflected by the palm becomes the reflected light R, and a part thereof enters the inspection window 121. The lighting device 1 detects the incident reflected light R and activates the inspection mode. Of course, what is held over the inspection light T to activate the inspection mode is not limited to the palm, but may be another body part of the inspector. Further, for example, a reflector that can reflect the inspection light T such as a reflector as shown in FIG. However, when holding the palm up, the inspector can activate the inspection mode without using any special tool.

  Further, when the inspection mode is activated, a palm or a reflector may be inserted into the inspection activation area (FIG. 2D), and the palm or the reflector is brought close to the inspection window 121 while being in the inspection activation area. It may be inserted (FIG. 2E). In the latter case, the inspector brings the palm or the reflector closer to a position determined from a distant position where the reflected light R is not determined as reflected light. In addition, by using visible light emitted from, for example, a red LED (Light emitting Diode) as the inspection light T, the light spot of the inspection light T reaching the side wall surface of the sinus can be visually recognized. Since the position of the optical axis is generally known, the inspection activation area can be easily estimated.

  When the inspector does not hold the palm or reflector over the inspection light T, the inspection light T radiated from the inspection window 121 hits the side wall surface of the sinus and is reflected. The sensitivity of the light receiver 252 (FIG. 5) of the illuminating device 1 (to be described later) and the light projecting / receiving unit 25 (see FIG. 5) so that the reflected light does not enter the inspection window 121 and be determined as the reflected light R (first condition). Adjust the mounting angle etc. in 3). Further, by such adjustment, the inspection activation area can be set between the inspection window 121 and the position where the inspection light T hits the side wall surface.

  Furthermore, the height of the ceiling of the cave from the floor is generally slightly higher than the height of a person (for example, about 2.5 m). Therefore, the sensitivity of the light receiver 252 and the mounting angle of the light projecting / receiving unit 25 are set so that the inspection mode is not activated by a work other than inspection or walking motion and reaches the inspection activation area if the hand is reached (second condition). Can be adjusted.

  Here, the distance between the inspection window 121 and the palm suitable for starting the inspection mode can be set to, for example, about 0 to 0.5 m. Moreover, when using white paper as a reflector, the upper limit of this distance can be about 1 m, and when using a mirror as a reflector, the upper limit of this distance can be about 2 m.

  Of course, the lighting device of the present invention is not limited to a device dedicated to a sinus. It is preferable to install the lighting device of the present invention in an environment where it is necessary to back up lighting by a storage battery at the time of a power failure and it is required to check the operating condition of this backup appropriately.

  Furthermore, the radiator used for determining the start of activation of the inspection mode is not limited to the light described above (inspection light T). As will be described later, an inspection electromagnetic wave may be emitted instead of the inspection light T by using an electromagnetic wave transmitter capable of emitting electromagnetic waves other than visible light and near infrared light. In this case, a reflected electromagnetic wave, which is an inspection electromagnetic wave reflected by the inspector's palm or reflector, is detected by an electromagnetic wave receiver installed in the illumination device.

  Here, when electromagnetic waves including visible light and near-infrared light are used as inspection waves (inspection light T), the radiation part of the transmitter (sender, electromagnetic wave transmitter) is exposed to the outside without providing the inspection window 121. And may be installed in the lighting device. In this case, the detector of the wave receiver (light receiver, electromagnetic wave receiver) may be exposed to the outside and installed in the lighting device. In this embodiment, the radiation axis (optical axis) of the inspection electromagnetic wave (inspection light T) can be extended obliquely downward.

  Further, as will be described later, an inspection ultrasonic wave may be emitted instead of the inspection light T by using an ultrasonic transmitter capable of emitting sound waves, particularly ultrasonic waves. In this case, reflected ultrasonic waves, which are inspection ultrasonic waves reflected by an inspector's palm or reflector, are detected by an ultrasonic receiver installed in the illumination device.

  Here, when the ultrasonic wave is an inspection ultrasonic wave, it is also preferable that the inspection window 121 is not installed. In this case, the radiation unit of the transmitter (ultrasonic transmitter) and the detection unit of the receiver (ultrasonic receiver) may be exposed to the outside and installed in the illumination device. In this embodiment, the inspection ultrasonic radiation axis can be extended obliquely downward.

  FIG. 3 is a configuration diagram of functional units in the lighting device 1.

  According to FIG. 3, the illuminating device 1 is provided with the power supply part 21, the illumination part 22, the control part 23, the storage battery 24, the light projection / reception unit 25, and the display lamp 26 as an internal function part. The power source unit 21 is an AC / DC power source, converts commercial AC power fed from the power line 4 into DC power, and supplies this DC power to the lighting unit 22 and the storage battery 24.

  The illumination unit 22 may be, for example, an LED illumination unit that includes an LED light source and is driven by DC power. Illumination light is radiated to the outside through the illumination window 122. Needless to say, the illumination unit 22 is not limited to an illumination unit using an LED, and may be an illumination unit using a fluorescent lamp, an electrothermal bulb, a discharge lamp, or the like.

  The control unit 23 controls (a) the lighting operation and the charging operation in the normal mode, (b) the discharging operation in the power failure mode, and (c) the inspection operation in the inspection mode in the lighting device 1.

  The storage battery 24 is a secondary battery that supplies direct current power to the illumination unit 22 in the event of a power failure when power supply from an external commercial power supply stops, and may be, for example, a lithium ion storage battery, a nickel hydride battery, or a lead storage battery. it can.

  The display lamp 26 may include a power supply display lamp (for example, emitting green light) and a power failure display lamp (for example, emitting red light). Here, it is also preferable that the power supply display lamp is turned on when commercial power is supplied, and the power failure display lamp is turned on at the time of power failure and inspection.

  The light projecting / receiving unit 25 emits inspection light T for determining the start of inspection related to power supply by the storage battery 24, and can detect the emitted and reflected light. Further, it is determined whether or not the detected light includes reflected light R that is emitted and reflected by the inspector. Here, when it is determined that the reflected light R is included in the light projecting / receiving unit 25, the control unit 23 starts an inspection mode related to power supply by the storage battery 24. Next, the control by the control unit 23 will be described in detail using a functional block diagram.

  FIG. 4 is a functional block diagram of the lighting device 1.

  According to FIG. 4, the commercial power source and the switch SW <b> 1 are installed outside the lighting device 1. Further, commercial AC power is always supplied between the common line wired from the commercial power source and the charging line. The switch line provided with SW1 has the same polarity as the charging line, and when SW1 is closed, commercial AC power is supplied between the common line and the switch line.

  In the power supply unit 21, the supplied AC power is converted into DC power. SW <b> 2 is a switch that turns on / off the supply of DC power from the power supply unit 21 to the illumination unit 22. SW3 is a switch for turning ON / OFF the supply of DC power (charging power) from the power supply unit 21 to the storage battery 24. Further, SW4 is a switch for turning on / off the supply of DC power from the storage battery 24 to the lighting unit 22, and SW5 is a switch for turning on / off the lighting operation of the lighting unit 22.

[Normal mode]
Similarly, the normal mode will be described first with reference to FIG. The normal mode is a mode in which the lighting operation of the lighting unit 22 is turned on / off by operating the SW 5 in a state where power is supplied from a commercial power source. In this case, SW5 actually opens and closes in conjunction with external SW1. In the normal mode, AC power that is constantly supplied between the common line and the charging line is input to the power supply unit 21 via the control unit 23, and DC power is constantly output from the power supply unit 21.

  In the normal mode, the control unit 23 closes SW2 to SW4. Therefore, DC power is constantly supplied from the power supply unit 21 to the illumination unit 22 and the storage battery 24. Here, although the storage battery 24 is also connected to the illumination part 22, the output voltage of the power supply part 21 is set higher than the output voltage of the storage battery 24 so that electric power is not supplied to the illumination part 22 from the storage battery 24 side. .

  Further, the control unit 23 monitors the supply of AC power between the common line and the switch line, that is, the opening and closing of the external SW1, and when the opening and closing of the external SW1 is detected, the control unit 23 opens and closes the SW5 to open the lighting unit 22. The lighting operation is controlled by turning it ON / OFF. Moreover, the control part 23 also monitors the battery voltage of the storage battery 24, and controls opening and closing of SW3 so that the storage battery 24 is not overcharged. For example, when a nickel metal hydride battery is used as the storage battery 24, SW3 is opened when the voltage rises to 1.8V per cell.

[Power failure mode]
Next, the power failure mode will be described with reference to FIG. Here, the power failure is a state in which power supply from the commercial power supply is interrupted. Even in the power failure mode, the control unit 23 closes SW <b> 2 to SW <b> 4, but the power supply from the power supply unit 21 is stopped, so that the illumination unit 22 is supplied with power from the storage battery 24. The control unit 23 also monitors the supply of AC power between the common line and the charging line. When a power failure is detected, the control unit 23 closes the SW 5 and turns on the illumination operation of the illumination unit 22. Here, the control unit 23 recognizes that the SW1 is opened, but gives priority to the detection of the power failure as described above, and closes the SW5 without interlocking with the SW1. The operation of turning on the illumination unit 22 with the power of the storage battery 24 is hereinafter referred to as a backup operation.

  The control unit 23 further controls the opening / closing of the SW 4 so that the storage battery 24 is not overdischarged. For example, when a nickel metal hydride battery is used, SW4 is opened when the voltage drops to 1.0 V per cell.

[Inspection mode]
Next, the inspection mode will be described with reference to FIG. As will be described later, the light projecting / receiving unit 25 includes a light projector 251 (FIG. 5) and a light receiver 252 (FIG. 5), and the inspection light T emitted from the light projector 251 is reflected outside the illumination device 1. It is detected and determined that the light has entered the light receiver 252. The inspection mode activation signal output from the light projecting / receiving unit 25 is input to the control unit 23, and the control unit 23 starts an inspection operation as to whether the backup operation is normally performed based on the input of the activation signal. Let

  Specifically, when the activation signal is input from the light projecting / receiving unit 25, the control unit 23 opens SW2 and SW3, and closes SW4 and SW5. Thereby, even if it is in the state where commercial electric power is supplied, since it can be in the state at the time of a power failure, the illuminating device 1 can confirm whether backup operation is performed normally.

  Naturally, the functional configuration of the lighting device 1 is not limited to the above-described embodiment. For example, various circuits can be applied if the wiring and switch configurations are such that power is supplied from the power supply unit 21 to the lighting unit 22 in the normal mode and power is supplied from the storage battery 24 to the lighting unit 22 in the power failure mode and the inspection mode.

  FIG. 5 is a functional block diagram of the light projecting / receiving unit 25 according to the present invention.

  According to FIG. 5, the light projecting / receiving unit 25 includes a light projector 251, a light receiver 252, an optical filter 253, an inspection instruction determination unit 27, and a light projecting drive unit 28.

  The projector 251 includes a light emitting element that emits visible light or near infrared light, and radiates inspection light T to the outside of the illumination device 1. As the light-emitting element, it is also preferable to use a red LED that emits light having a wavelength of 600 to 780 nanometers (nm) or an infrared LED that emits light having a wavelength of 780 to 1100 nm. The light projecting drive unit 28 is a drive / control unit for starting and controlling the light projector 251.

  Instead of the projector 251, it is possible to use an electromagnetic wave transmitter as a transmitter capable of emitting electromagnetic waves other than visible light and near infrared light. In this case, an inspection electromagnetic wave is used instead of the inspection light T as the inspection wave for determining the start of the inspection. As yet another embodiment, an ultrasonic transmitter as a transmitter capable of emitting ultrasonic waves may be used instead of the projector 251. In this case, inspection ultrasonic waves are used instead of the inspection light T as the inspection wave.

  The light receiver 252 is a light receiving means including a light receiving element capable of detecting the reflected light R emitted and reflected from the projector 251. As the light receiving element, for example, a photodiode can be used, and it is preferable that the light receiving element has a light receiving sensitivity within a wavelength of 600 to 1100 nm which is a wavelength of light emitted from the light emitting element.

  Instead of the light receiver 252, it is possible to use an electromagnetic wave receiver as a wave receiver capable of detecting electromagnetic waves other than visible light and near infrared light. In this case, instead of the reflected light R, a reflected electromagnetic wave radiated and reflected from the electromagnetic wave transmitter is used. As still another embodiment, an ultrasonic receiver as a receiver capable of detecting sound waves, particularly ultrasonic waves, may be used instead of the light receiver 252. In this case, instead of the reflected light R, reflected ultrasonic waves radiated and reflected from the ultrasonic transmitter are used.

  Returning to FIG. 5, by limiting the inspection light T to, for example, visible light, it is possible to reduce malfunctions due to disturbance light in the infrared light region. In this case, a light emitting element having a light emission wavelength of 600 to 780 nm, for example, is used, and a light receiving element having a light receiving sensitivity of, for example, 600 to 750 nm, is used. As a result, it is possible to avoid detecting disturbance light in the infrared light region as reflected light R.

  Thus, the projector 251 emits the inspection light T including a wavelength within a predetermined range, and the light receiver 252 has a higher sensitivity for light having a wavelength within the predetermined range than light having a wavelength outside the predetermined range. It is also preferable to detect by. Thereby, erroneous start of the inspection mode due to disturbance light or the like can be suppressed.

  The optical filter 253 is, for example, an optical low-pass filter, cuts light having a wavelength shorter than the wavelength of the inspection light T emitted from the light emitting element, and is longer than the inspection light T emitted from the light emitting element and the inspection light T. It is also preferable to have characteristics that allow light of a wavelength to pass therethrough. For example, an optical filter having a cut wavelength of 600 nm and a transmittance of less than 15% at a wavelength of 580 nm and greater than 85% at a wavelength of 620 nm is used. When such an optical filter 253 is used, and the projector 251 and the receiver 252 whose emission wavelength and light receiving sensitivity are limited to the 600 to 700 nm range as described above, the wavelength region including the wavelength of the inspection light T is used. Both short wavelength light and long wavelength light can be excluded, and as a result, malfunctions can be further reduced.

  As described above, the light receiver 252 detects light having a wavelength within a predetermined range including the wavelength of the inspection light T with higher sensitivity than light having a wavelength outside the predetermined range, and uses an optical filter or the like. It is also preferable to selectively detect the light with a wavelength outside the predetermined range. Thereby, the erroneous start of the inspection mode due to disturbance light or the like can be more reliably suppressed.

  Note that an ultrasonic (electromagnetic) transmitter and an ultrasonic (electromagnetic) receiver are used instead of the transmitter 251 and the receiver 252, and the ultrasonic (electromagnetic) transmitter includes ultrasonic waves (electromagnetic waves) including a wavelength within a predetermined range. ), And the ultrasonic wave (electromagnetic wave) receiver has a higher sensitivity than the ultrasonic wave (electromagnetic wave) having a wavelength within the predetermined range compared to the ultrasonic wave (electromagnetic wave) having a wavelength outside the predetermined range, and / or Alternatively, it may be selectively detected by distinguishing from waves having wavelengths outside this predetermined range. Even in such an embodiment, erroneous start of the inspection mode can be suppressed.

  The inspection instruction determination unit 27 determines whether or not the light detected by the light receiver 252 includes the reflected light R emitted from the projector 251 and reflected by the inspector, and the control unit 23 uses the determination result as an activation signal. (FIG. 4). Specifically, in the present embodiment, the inspection instruction determination unit 27 amplifies the light incident on the light receiver 253, demodulates the incident light in synchronization with the drive cycle of the light projecting drive unit 28, and generates an activation signal (determination result). Signal). Next, operations of the inspection instruction determination unit 27 and the light projecting drive unit 28 of the light projector 251 will be described.

  FIG. 6 is a timing chart showing operations of the inspection instruction determination unit 27 and the light projecting drive unit 28 in the light projecting / receiving unit 25.

  According to FIG. 6A, a pulse signal having a preset pulse width with a predetermined cycle is output at output A (output at position A in FIG. 5) which is a drive output from the light projecting drive unit 28. ing. The light projecting drive unit 28 drives the light emitter 251 with this output. For example, an ON operation of 0.1 milliseconds (ms) can be performed with a period of 1 ms.

  In such a state where the inspector has not put his hand over the inspection light T in the state of the output A, the output B from the light receiver 252 (the output at the position B in FIG. 5) includes an output due to disturbance light. It only appears. This output is input to CMP1 + of the inspection instruction determination unit 27. Further, as shown in the output G in FIG. 6B (output at the position G in FIG. 5), the inverted signal of the output A is divided and input to CMP1-.

  Here, when the output A is at the HIGH (H) level, the voltage division ratio in this partial pressure is adjusted to a level that is just before CMP1 inverts in the output B composed of ambient light and does not invert. As a result, during the period in which the output A is at the LOW (L) level, the level of CMP1- is high even if there is a predetermined output due to ambient light, so that CMP1 does not invert. On the other hand, during the period when the output A is at the H level, the level of CMP1- is low and CMP1 is easily inverted, so that the output related to the reflected light R can be detected more reliably at the output B.

  Returning to FIG. 6A, the pulse output of CMP1 generated by the output B is converted into a voltage by the demodulation circuit, output to the CMP2 as the output D, converted to the H / L level by the CMP2, and output E Become. The output E is reversed, and the output F indicating the determination result as to whether or not the inspector's hand is held is output from the light projecting / receiving unit 25.

  As described above, according to the present embodiment, the light projecting drive unit 28 outputs a signal modulated at a predetermined frequency to the light projector 251, and causes the light projector 251 to emit light modulated at the predetermined frequency as the inspection light T. . In addition, the inspection instruction determination unit 27 demodulates the detection signal output from the light receiver 252 at a predetermined frequency. Based on the demodulated detection signal, “the light detected by the light receiver 252 radiates from the projector 251. It is determined whether or not the reflected light R reflected by the inspector is included. Accordingly, it is possible to prevent the unnecessary inspection mode from being activated by receiving disturbance light or the like unrelated to the predetermined frequency.

  Here, in response to the determination that the change from the H level to the L level in the output F is “including the reflected light R”, the change from the L level to the H level is “not including the reflected light R”. It corresponds to having made the determination. The inspection mode start signal recognized by the control unit 23 upon receiving the output F from the light projecting / receiving unit 25 is an inversion of the output F. Accordingly, in response to the determination that the inspection mode activation signal rises from OFF to ON as “includes reflected light R”, the fall from ON to OFF indicates “does not include reflected light R”. This corresponds to the determination being made.

  Of course, the circuit configuration and operation of the inspection instruction determination unit 27 are not limited to those described above. For example, when the light receiver 252 receives light having an intensity equal to or higher than a predetermined intensity threshold, an apparatus that outputs an H level determination result signal indicating that “including the reflected light R” is applied as the inspection instruction determination unit. Is possible. The determination result signal can also take various forms. For example, as the determination result signal, one or more predetermined numbers that are output at the time of determination of “including the reflected light R” or “not including the reflected light R”. It is also possible to use the pulse signal.

  As another embodiment, an ultrasonic wave (electromagnetic wave) transmitter and an ultrasonic wave (electromagnetic wave) receiver are used instead of the transmitter 251 and the receiver 252, and an ultrasonic wave (electromagnetic wave) is used instead of the light projecting drive unit 28. It is also possible to input the same output as the output A and the output B to the inspection instruction determination unit 27 using the drive unit. Also in this case, for example, an output similar to the output B shown in FIG. 6 is generated depending on the presence or absence of the hand of the inspector. As a result, an output similar to the output F can be acquired from the inspection instruction determination unit 27. Here, in response to the determination that the change from the H level to the L level in the output F includes “reflected ultrasonic waves (electromagnetic waves) reflected by the inspector”, the L level changes to the H level. This corresponds to the determination that the change does not include the reflected ultrasonic wave (electromagnetic wave) reflected by the inspector.

  FIG. 7 is a schematic diagram illustrating an installation example of the light projecting / receiving unit 25.

  In the illuminating device 1, the light projecting / receiving unit 25 is installed so that the inspection light T emitted from the light projector 251 exits from the inspection window 121 to the outside of the device. In the installation example of FIG. 7A, the optical axis of the inspection light T emitted from the projector 251 is parallel to the longitudinal direction (x-axis direction) of the illumination device 1, and the inspection light T along the optical axis is The light enters the window 121 perpendicularly and exits to the outside. Therefore, a part of the inspection light T is reflected by the inner surface 121 n of the inspection window 121 and becomes reflected light r and enters the light receiver 252. Further, another part of the inspection light T is reflected inside the outer surface 121 s of the inspection window 121, and enters the light receiver 252 as reflected light r ′. Such reflected lights r and r 'can cause malfunction.

Next, in the installation examples of FIGS. 7B1 and 7B2, the light projecting / receiving unit 25 is
(A) The optical axis of the inspection light T radiated from the projector 251 is inclined downward (+ z direction) from the longitudinal direction (x-axis direction) of the illumination device 1, and (b) the projector 251 is oblique to the light receiver 252. It is installed so as to be located below. Here, in the case of (a), the optical axis of the inspection light T is inclined at an angle within a predetermined acute angle range with respect to the normal line of the surface of the inspection window 121. According to such an installation example, it is possible to reduce the incidence of the reflected light r and r ′ described with reference to FIG. 7A to the light projecting / receiving unit 25 (light receiver 252).

Furthermore, in the installation example of FIG. 7 (C1) and (C2), the light projecting / receiving unit 25 is
(C) The optical axis of the inspection light T radiated from the projector 251 is tilted downward (+ z direction) from the longitudinal direction (x-axis direction) of the illumination device 1, and (d) the projector 251 and the light receiver 252 are They are installed at the same height (in the z-axis direction). Also with this installation example, it is possible to reduce the incidence of the reflected light r and r ′ described with reference to FIG. The distance d ₂ between the inner surface of the exit positions as inspection window 121 of the projector 251 in this installation example, a sufficiently small value as compared with the distance d ₁ corresponds at the installation example of FIG. 7 (B1) and (B2) It can be set. As a result, complex reflected light on the inner surface of the cover 12 as shown in FIG. 7B1 can be reduced, and malfunction can be further suppressed.

  FIG. 8 is a timing chart showing some embodiments at the start of the inspection operation according to the present invention.

  FIG. 8A shows the output of the light projecting / receiving unit 25 and the recognition logic of the control unit 23 when the inspector holds his / her hand over the inspection light T in the inspection activation area. According to the figure, the control unit 23 receives the output F (FIG. 6) when the inspector holds his / her hand and recognizes that the inspection mode activation signal is turned on.

  Next, FIG. 8B shows an embodiment in which the inspection operation is turned ON (inspection mode is activated) only during a period in which the inspection mode activation signal is ON. Here, during startup of the inspection mode, SW2 is opened and SW5 is closed. Before the inspection operation is turned on and after the inspection operation is turned on, the operation of SW5 follows SW1.

  In this embodiment, the control unit 23 starts the inspection operation when the inspection mode activation signal rises from OFF to ON, that is, when the inspection instruction determination unit 27 determines that the reflected light R is included. Further, when the inspection mode activation signal falls from ON to OFF, that is, when the inspection instruction determination unit 27 determines that the reflected light R is not included, the inspection operation is terminated.

  Further, FIG. 8C shows an embodiment in which the inspection operation is turned on for a preset inspection setting time t when the inspection mode activation signal is turned from OFF to ON. In this case, the control unit 23 starts the inspection operation when the inspection mode activation signal rises from OFF to ON, that is, when the inspection instruction determination unit 27 determines that the reflected light R is included, The inspection operation is terminated after the inspection set time t has elapsed.

  In this embodiment, for example, even if the inspection window 121 is gradually soiled, reflected light due to this soiling is detected by the light receiver 252 at a predetermined intensity or higher, and the inspection mode start signal for starting the inspection mode is always ON. Therefore, it is possible to avoid a situation in which the inspection operation is continuously turned on. In addition, in order to activate the inspection mode for a necessary time, it is not necessary to keep a hand or a reflector over the inspection light T. That is, once the inspection mode is activated by holding a hand or a reflector, the inspection mode continues for a predetermined time even if the holding operation is stopped.

Further, in the embodiment shown in FIG. 8D, as in FIG. 8C, when the inspection mode activation signal is turned from OFF to ON, the inspection operation is turned on for a preset inspection setting time t. To. However, in this embodiment, even if the inspection mode start signal is switched from OFF to ON during the predetermined inspection operation suspension time t _{R after} the completion of the ON state of the inspection operation, the inspection operation does not start and is turned OFF. Will remain. When the inspection operation suspension time t _R has elapsed, the inspection mode activation signal is turned from OFF to ON when the inspection mode activation signal is turned from OFF to ON.

In this way, by setting the inspection operation pause time t _R , it is possible to prevent the operation of continuously starting the inspection mode and unnecessarily consuming the power stored in the storage battery 24. Moreover, after the inspection operation, at least during inspection operation downtime t _R, it is possible to reliably secure the charging time for the battery 24. Here, the inspection operation suspension time t _R may be set to a time during which the storage battery 24 can be charged with power equal to or higher than the power supplied from the storage battery 24 in the inspection operation during the inspection setting time t.

  FIG. 9 is a timing chart showing another embodiment at the start of the inspection operation according to the present invention.

According to FIG. 9, when the inspection mode activation signal changes from OFF to ON and then changes from ON to OFF, the inspection operation is turned ON and is turned OFF after a preset operation time t has elapsed. In this case, when the control unit 23 determines that the reflected light R is not included after the inspection instruction determination unit 27 determines that the reflected light R is included, the control operation is started. Here, during the period in which the inspection operation is ON, the illumination unit 22 is supplied with electric power from the storage battery 24 and the illumination is turned on. In this case, the time t _C when the illumination is turned on substantially coincides with the operation time t.

  Also in such an embodiment, when the inspection mode activation signal is always turned on due to dirt on the inspection window 121, it is possible to avoid a situation in which the inspection operation is continuously turned on. In addition, if the inspection mode activation signal is limited to a signal having a pulse width within a predetermined range, the disturbance light is simply compared to the case where the inspection operation is turned on in accordance with the inspection mode activation signal being changed from OFF to ON. It is possible to more reliably suppress malfunctions in the inspection mode due to the above.

  Here, before the operation time t of the inspection operation, if the illumination is in the ON state (as a normal mode), whether or not the inspection operation has been started cannot be distinguished by the illumination condition of the illumination unit 22. In this case, for example, by confirming the lighting state of the display lamp from the display window 123, it is recognized that the inspection operation is being performed.

  FIG. 10 is a timing chart showing still another embodiment at the start of the inspection operation according to the present invention.

According to FIG. 10, also in this embodiment, when the inspection mode activation signal changes from OFF to ON and then changes from ON to OFF, the inspection operation is turned ON and turned OFF after a preset operation time t has elapsed. It becomes. However, in the present embodiment, the illumination unit 22 is in the OFF state for the time t ₁ from the time when the inspection operation is turned on, and then is turned on as the inspection operation for the time t _C. That is, even if the illumination is in the ON state before the operation time t of the inspection operation, the illumination is temporarily turned off for the time t ₁ and then turned on.

  In general, when the inspector looks at the display window 123 for mode confirmation when the illumination is on, the illumination light from the illumination window 122 is dazzling and it is difficult to confirm the mode. However, according to the embodiment of FIG. 10 described above, since the illumination is turned off when the inspection mode is activated, the inspector can recognize the activation of the inspection mode without gazing at the display window 123. The burden of inspection confirmation is reduced.

  FIG. 11 is a timing chart showing still another embodiment at the start of the inspection operation according to the present invention.

According to FIG. 11 (A), when the inspection mode start signal changes from OFF to ON and the behavior from ON to OFF (the behavior of one pulse) is performed twice during the determination set time t _K , As an operation, the inspection mode 2 is activated for a time t. Also, in this case, as a sign indicating the start of the inspection operation, the illumination is turned off simultaneously with the start of the inspection mode 2, and then the ON and OFF sets are repeated twice, and then the inspection operation is turned on for the time t _C. . The inspector can confirm that the inspection mode 2 has started by visually recognizing that the lighting has blinked twice. Here, such a time t ₁ ~t ₅ which defines the notification inspection mode by flashing illumination is determined so blinking becomes visible determinable rate.

Further, according to FIG. 11 (B), when the inspection mode start signal is turned from OFF to ON and the behavior from ON to OFF (the behavior of one pulse) is performed three times during the determination set time t _K. As a check operation, check mode 3 is activated for a time t. Further, in this case, the illumination of the illumination unit 22 is turned off simultaneously with the start of the inspection mode 3 as a sign indicating the start of the inspection operation, and after repeating the ON and OFF group three times, the inspection operation is performed only for the time t _C. Turns on. The inspector can confirm that the inspection mode 3 has been activated by visually recognizing that the lighting has blinked three times. Here, the times t ₁ to t ₇ that define the notification of the inspection mode by the blinking of such illumination are also determined so that the blinking can be visually determined.

For example, in FIGS. 11A and 11B, t _k is 0.3 to 2 seconds (s), t _S is 0.02 to 0.3 s, t ₁ is 0.3 s to ₁ s, and t _{2 to} t. It is also preferable to set a time such as 0.1 to 0.5 s as ₇ .

Further, as inspection modes 1 to 3 as the first to third types of inspection operations, for example,
(A) Inspection mode 1: a mode for performing an inspection operation as to whether or not electric power is supplied to the illumination unit 22 by the storage battery 24;
(B) Inspection mode 2: a mode for performing an inspection operation for the degree of charge in the storage battery 24, and (c) inspection mode 3: a mode for performing an operation for checking an operation log related to power supply of the storage battery 24. In addition, when starting in any inspection mode, it is also preferable that the illumination part 22 is in an ON state by the power supply from the storage battery 24.

  Further, the charge level in the inspection mode 2 may be confirmed by acquiring a charge amount (battery voltage) signal from a dedicated terminal of the lighting device 1 during the start of the inspection mode 2 or installed in the lighting device 1. It is also preferable that the charge can be confirmed with a digital indicator. Furthermore, the operation log in the inspection mode 3 may be confirmed by obtaining an operation log signal from a dedicated terminal of the lighting device 1 or preferably by a display installed in the lighting device 1.

Thus, in this embodiment, when the inspection mode activation signal is turned ON and OFF (the behavior of one pulse) N times during the determination set time t _K , the inspection mode N is activated for the time t. To do. That is, the control unit 23 performs the number of times that the inspection instruction determination unit 27 performs a combination of “determination that the reflected light R is included” and subsequent “determination that the reflected light R is not included” within the determination setting time t _K. Accordingly, the corresponding inspection mode N is selected from the inspection modes 1 to 3 previously associated with the number of times, and the selected inspection mode N is activated. As a result, the desired inspection mode N can be selected and activated by an easy operation of holding the hand N times (waving his hand) with respect to the inspection light T during the determination set time t _K.

  Further, in the present embodiment, the control unit 23 selects the corresponding start / stop count N among the start / stop counts associated in advance for each type according to the type of the inspection mode that has been activated, The operation of starting and stopping the power supply to the illumination unit 22 is repeated by the selected number of start / stop times N. The type of the inspection mode is notified by such blinking of the illumination, and the inspector who has visually recognized N blinks can recognize that the inspection mode N has been activated.

  FIG. 12 is a timing chart showing still another embodiment at the start of the inspection operation according to the present invention.

In the embodiment shown in FIG. 12, a new inspection mode can be activated before the activated inspection mode 2 is completed. For example, when the inspection mode 3 is activated, the inspector performs an activation operation (an operation of shaking hands) three times so that the inspection mode activation signal is output three times. However, if the activation operation is insufficient and the inspection mode activation signal is generated only twice during the determination set time t _K1 , the inspection mode 2 is activated. The inspector recognizes this malfunction by visually recognizing the blinking of the light twice at the start of the inspection operation.

The inspector then performs the activation operation (waving hand) three times again, and outputs the inspection mode activation signal three times during the determination set time t _K2 without waiting for the completion of the inspection mode 2, and the desired inspection mode. 3 is activated. Here, it is confirmed that the inspection mode 3 is activated by the blinking of the illumination three times at the start of the inspection operation.

  As described above, according to the present embodiment, when a notification of unintended inspection mode activation (blinking of illumination) is visually recognized, it is possible to quickly activate a desired inspection mode.

  FIG. 13 is a timing chart showing the operation of each component in the normal mode, the power failure mode, and the inspection mode of the lighting device 1 according to the present invention.

  In the normal mode shown in FIG. 13A, the illumination is turned ON / OFF by opening / closing SW5 in conjunction with the opening / closing of SW1. That is, when SW1 is closed, SW5 is closed and the illumination is turned on. Further, when the battery voltage of the storage battery 24 being charged rises to a predetermined upper threshold voltage (about 1.8 V for a nickel metal hydride battery) per cell, the SW3 is opened so that the storage battery is not overcharged. It is also preferable.

  In the power failure mode shown in FIG. 13B, power is supplied from the storage battery 24 to the illumination unit 22 regardless of whether the SW1 is opened or closed, and at the same time, the SW5 is closed to turn on the illumination. Here, when SW1 is closed, the illumination is in the ON state even before and after the power failure, so it is not possible to determine whether or not the power failure has occurred by simply observing the illumination. This determination is made based on whether or not the power failure display lamp is lit. In a power failure with SW1 open, the illumination is turned on simultaneously with the power failure. During a power failure, the battery voltage of the storage battery 24 decreases due to the power consumption of the storage battery 24. It is also preferable to open SW4 so that overdischarge does not occur when this battery voltage drops to a predetermined lower threshold voltage (about 1.0 V for a nickel metal hydride battery) per cell.

  Further, in the inspection mode shown in FIG. 13C, when SW1 is closed, the illumination is on even before and after the inspection mode. However, the activation of the inspection mode can be easily confirmed because the illumination blinks as the inspection mode notification operation at the activation timing. Similarly, when the switch SW1 is open, the illumination is turned on after the illumination blinks as the inspection mode notification operation, so that the activation of the inspection mode can be confirmed.

  As described above, according to the present invention, the determination is made that “the wave detected by the wave receiving means (light receiver) includes the reflected wave emitted from the wave transmitting means (light projector) and reflected by the inspector”. In the case, the inspection operation of the lighting device is started. Accordingly, the inspection operation can be easily started without taking out an operation tool from the inside of the apparatus or using a special tool from the outside.

  In addition, since it is not necessary to take out a tool for operation from the inside of the device or use a special tool from the outside in order to instruct the start of the inspection operation, the entire lighting device can be sealed and waterproof. It becomes easy to improve the property and dust resistance. Therefore, for example, it is possible to provide a lighting device that can be used with high reliability even in a high-humidity environment such as a tunnel or in a dusty environment such as a tunnel.

  It should be noted that all of the embodiments described above are illustrative of the present invention and are not intended to be limiting, and the present invention can be implemented in other various modifications and changes. Therefore, the scope of the present invention is defined only by the claims and their equivalents.
