Description

  Embodiments described herein relate generally to a lamp body cleaning apparatus and a lamp body cleaning method.

There are lighting devices installed outdoors. For example, there are an air traffic sign light embedded in a taxiway at an airport, a wall light embedded in a wall surface of a tunnel, a road surface light embedded in a road surface, and the like. Such an illuminating device includes a lamp exposed from a road surface and the like, a light source provided inside the lamp, and the like. The light emitted from the light source is emitted to the outside of the lamp body through optical elements such as a light projection window and a lens provided in the lamp body.
Here, the brightness of the emitted light may decrease when the illumination device installed outdoors is contaminated. Therefore, a technique has been proposed in which dry ice particles are sprayed onto the lamp body to clean the lamp body, and the cleaning effect is confirmed by measuring the luminous intensity of light emitted from the cleaned lighting device.

In such a technique, a nozzle for discharging particles of dry ice, a measurement unit for measuring emitted light, and a camera for photographing a lamp are provided side by side at the tip of an arm of an industrial robot, for example. . When cleaning is performed, the nozzle is brought close to the lamp body, so that the measuring unit and the camera are also brought closer to the lamp body. If the distance between the measurement unit and the camera and the lamp body is shortened, measurement and photographing are facilitated.
However, when the lamp is cleaned, deposits and the like attached to the lamp are scattered. Therefore, if the distance between the measurement unit and the camera and the lamp body is shortened, dust such as scattered deposits easily adheres to the measurement unit and the camera. If dust adheres to the measurement unit and the camera, these functions may be deteriorated.

In this case, these functions can be recovered by cleaning the measuring unit and the camera every time the cleaning is performed or every certain period.
However, in general, there are a large number of aerial beacon lamps to be cleaned in one cleaning operation. For this reason, if the process of cleaning the measuring unit and the camera is provided in the process of the cleaning operation, the time of the cleaning operation becomes longer correspondingly, and the time zone during which the taxiway or the road cannot be used may be expanded.
Therefore, it has been desired to develop a technique capable of shortening the cleaning work time.

JP 2005-146586 A

  The problem to be solved by the present invention is to provide a lamp body cleaning device and a lamp body cleaning method capable of shortening the time of the cleaning operation.

  The lamp cleaning device according to the embodiment includes a nozzle; a measurement unit capable of measuring light emitted from a lamp exposed from an outdoor road surface or wall surface; a vehicle; and the nozzle and the measurement unit provided in the vehicle. And a moving unit capable of changing the positions of the nozzle and the measurement unit; a cleaning material supply unit provided in the vehicle and capable of supplying a cleaning material to the nozzle; and a measurement function of the measurement unit, An adhering matter suppressing part that suppresses inhibition by dirt from the outside adhering.

  According to the embodiment of the present invention, it is possible to provide a lamp body cleaning apparatus and a lamp body cleaning method that can shorten the time of the cleaning operation.

It is a schematic side view for illustrating the lamp body cleaning apparatus according to the present embodiment. It is a schematic plan view of a lamp body cleaning apparatus. It is a schematic diagram for illustrating the front-end | tip part of a moving part.

Hereinafter, embodiments will be illustrated with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
The lamp cleaning apparatus and lamp cleaning method according to the embodiment include, for example, an air traffic sign light embedded in an airport taxiway, a wall lamp embedded in a tunnel wall, a road surface embedded in a road surface, etc. It can be applied to lights. However, the object to be cleaned is not limited to that illustrated, and may be an illumination device including a lamp exposed from an outdoor road surface or wall surface.

Hereinafter, as an example, a case where the lighting device is an aerial beacon will be described as an example.
Aviation sign lights are embedded in road surfaces such as taxiways. The air traffic sign lamp includes a lamp body, a light source provided inside the lamp body, and optical elements such as a light projection window and a lens exposed on the outer surface of the lamp body. The lamp projects from the road surface. The light emitted from the light source is emitted to the outside of the lamp body through the optical element.
Since the air traffic light is embedded in the road surface, sand or earth may adhere to the optical element or the optical element may be covered with sand or earth. Aircraft tires ride on the lamp. Therefore, the tire material may adhere to the optical element. If a deposit adheres to the optical element or the optical element is covered with sand or earth, the luminous intensity of the light emitted from the optical element may decrease. Therefore, the aviation beacon is cleaned regularly or as needed.

The cleaning material used in the lamp cleaning apparatus and lamp cleaning method according to the embodiment can be, for example, water, sodium bicarbonate (sodium bicarbonate), dry ice, or the like. However, the cleaning material is not limited to those illustrated, and any cleaning material that does not cause damage to elements made of glass or the like provided in the lamp body may be used.
In the following, a case where the cleaning material is dry ice will be described as an example.

(Lamp cleaning equipment)
FIG. 1 is a schematic side view for illustrating a lamp body cleaning device 1 according to the present embodiment.
FIG. 2 is a schematic plan view of the lamp cleaning device 1.
FIG. 3 is a schematic diagram for illustrating the tip portion of the moving unit 42.
As shown in FIGS. 1 and 2, the lamp cleaning device 1 includes a vehicle 10, a cleaning material supply unit 20, a power unit 30, a cleaning unit 40, a measurement unit 50, a photographing unit 60, and a control unit 70. ing.

  The vehicle 10 moves the cleaning material supply unit 20, the power unit 30, the cleaning unit 40, and the control unit 70 together. The vehicle 10 only needs to be equipped with an engine, a motor, and the like and capable of transporting a load. In this case, the vehicle 10 may be moved on a track or the like. However, in consideration of the degree of freedom and versatility of the cleaning operation, it is preferable to use a vehicle that can travel on the road surface 102 to some extent, such as an automobile.

In this case, the vehicle 10 is provided with a cleaning material supply unit 20, a power unit 30, a cleaning unit 40, and a control unit 70. Therefore, it is preferable that the vehicle 10 can secure these installation spaces. Further, since the cleaning work is often performed outdoors, the vehicle 10 is preferably configured to protect the cleaning material supply unit 20, the power unit 30, the cleaning unit 40, and the control unit 70 from rain and wind. . The vehicle 10 can be, for example, a truck, a wagon car, a one-box car, or the like. The vehicle 10 illustrated in FIGS. 1 and 2 is a truck.
In the following, a case where the vehicle 10 is a truck will be described as an example.

The loading platform 11 of the vehicle 10 can be provided with a cleaning material supply unit 20, a power unit 30, a cleaning unit 40, and a control unit 70. The cargo bed 11 is provided with an opening 11a. When cleaning is performed, the nozzle 41 and the measurement unit 50 protrude outside through the opening 11a. When the cleaning is completed, the nozzle 41 and the measurement unit 50 are accommodated in the space above the loading platform 11.
Moreover, the cover 12 which covers the upper part of the loading platform 11, and the door which opens and closes the opening 11a can be provided.

  In addition, although the case where the opening 11a was provided in the loading platform 11 was illustrated, the opening 11a should just be provided in the position where the nozzle 41 and the measurement part 50 can approach the lamp body 101. FIG. When the object to be cleaned is the air traffic light 100, the object to be cleaned is provided on the road surface 102. Therefore, the opening 11a is preferably provided on the side surface 12a on the rear side of the loading platform 11 and the cover 12. When the object to be cleaned is provided at a position higher than the road surface 102, such as a wall surface of a tunnel, the opening 11a can be provided on the side surface of the cover 12, the ceiling surface, or the like.

  A display unit 13 can be provided in the driver's seat of the vehicle 10. The display unit 13 is electrically connected to the control unit 70. An image of the lamp 101 photographed by the photographing unit 60 is displayed on the display unit 13. In addition, the display unit 13 can display an area where the cleaning unit 40 can easily perform cleaning. In this case, the driver can move the vehicle 10 so that the image of the lamp body 101 falls within the area displayed on the display unit 13.

The cleaning material supply unit 20 supplies the cleaning material to the nozzle 41.
The cleaning material supply unit 20 includes a blower unit 21 and a storage unit 22.
As shown in FIG. 2, the blower unit 21 can be connected to the nozzle 41 via a pipe 23. The air blowing unit 21 supplies air to the nozzle 41 via the pipe 23. The blower 21 can be, for example, a blower or a compressor. In this case, it is preferable to use a compressor having a high discharge pressure in consideration of improvement in cleaning power and adjustment of cleaning power. In addition, when it is set as the comparatively small lamp body washing | cleaning apparatus 1, it is good also as a pressure cylinder etc. in which the pressurized air was accommodated.

The storage unit 22 is connected to a pipe 23 between the air blowing unit 21 that blows high-pressure air and the nozzle 41. The storage unit 22 stores the cleaning material. The cleaning material can be dry ice. As the dry ice, for example, one formed in a minute solid form such as a substantially cylindrical particulate pellet having a diameter of about 1 mm to 3 mm and a length of about 6 mm to 10 mm can be used. A crushing device or the like may be provided to crush the dry ice lump.
The cleaning material stored in the storage unit 22 is supplied to the inside of the pipe 23 between the blower unit 21 and the nozzle 41. The supply of the cleaning material can be performed by gravity, but can also be sucked out into the pipe 23 by the suction force due to the venturi effect.
In addition, the ventilation part 21 and the accommodating part 22 can also be integrated. For example, particulate dry ice and air can be mixed in advance and supplied to the nozzle 41.
In addition, the cleaning material may not be stored in the storage unit 22, or the supply of the cleaning material stored in the storage unit 22 may be stopped by a shutter or the like so that only high-pressure air is ejected from the nozzle 41. .
The same configuration can be used when baking soda or the like is used as the cleaning material.
When water or the like is used as the cleaning material, a so-called high pressure washer may be used.

  The power unit 30 supplies power to the cleaning material supply unit 20, the cleaning unit 40, the control unit 70, and the like. The power unit 30 can be, for example, an engine generator. The power unit 30 may be a storage battery, for example. However, in consideration of maintainability, versatility, weight, space saving, and the like, the power unit 30 is preferably an engine generator.

The cleaning unit 40 includes a nozzle 41 and a moving unit 42.
The nozzle 41 is provided at the tip of the moving part 42. The nozzle 41 has a cylindrical shape, and the pipe 23 is connected to one end thereof. A mixture of particulate dry ice and high-pressure air is discharged from the opening at the other end of the nozzle 41. Alternatively, only high-pressure air is ejected, and dust, dirt, dirt, or the like adhering to the surface is cleaned by the high-pressure air.

The moving unit 42 changes the positions of the nozzle 41 and the measuring unit 50. For example, when cleaning is performed, the moving unit 42 moves the nozzle 41 and the measuring unit 50 to the vicinity of the lamp body 101. When the cleaning is completed, the moving unit 42 stores the nozzle 41 and the measuring unit 50 in the space above the loading platform 11.
The moving unit 42 can be, for example, a vertical articulated robot. However, the moving unit 42 is not limited to the vertical articulated robot. The moving unit 42 only needs to change the positions of the nozzle 41 and the measuring unit 50 in a predetermined space. For example, the moving unit 42 may be a combination of a plurality of single-axis robots. However, in consideration of maintainability, versatility, weight, space saving, and the like, the moving unit 42 is preferably a vertical articulated robot.

  The measuring unit 50 is provided at the distal end portion of the moving unit 42. The measurement unit 50 can be provided side by side with the nozzle 41. The measurement unit 50 is electrically connected to the control unit 70. The measuring unit 50 measures the light emitted from the lamp body 101 and converts the measured value into an electric signal. The value converted into the electric signal is input to the control unit 70. For example, the measurement unit 50 measures the luminous intensity of light emitted from an optical element provided in the lamp body 101, and converts the measured luminous intensity into an electrical signal. The luminous intensity converted into the electrical signal is input to the control unit 70. In this case, the measurement unit 50 can be a photometer or the like.

As shown in FIG. 3, a holding portion 42 a and a holding portion 42 b are provided at the distal end portion of the moving portion 42. The holding part 42a and the holding part 42b can be provided side by side.
The nozzle 41 is held by the holding portion 42a. The holding part 42 a may be rotatably provided at the tip part of the moving part 42, or may be fixed to the tip part of the moving part 42. The rotation of the holding portion 42a can be performed by a control motor such as a servo motor, or can be performed by an air cylinder, a solenoid, or the like. If the holding part 42a is rotatably provided, it becomes easy to change the discharge direction of the cleaning material. If the holding portion 42a is fixed to the tip portion of the moving portion 42, the configuration of the tip portion of the moving portion 42 can be simplified.

The measurement unit 50 is held by the holding unit 42b. The holding portion 42b is rotatably provided at the tip portion of the moving portion 42. The rotation of the holding portion 42b can be performed by a control motor such as a servo motor, or can be performed by an air cylinder, a solenoid, or the like.
If the holding part 42b is rotatably provided, it becomes easy to change the measurement direction.
In addition, if the holding unit 42b is rotatably provided, the measuring unit 50 can be moved to the retracted position when cleaning is performed.
Here, when cleaning is performed, the cleaning material is discharged from the nozzle 41. When the discharged cleaning material collides with the lamp body 101, the deposits attached to the lamp body 101 are scattered around. Since the measurement unit 50 is provided in the vicinity of the nozzle 41, dust such as scattered deposits may adhere to the detection surface 50a of the measurement unit 50. In addition, since the measurement is facilitated if the distance between the measurement unit 50 and the lamp body 101 is shortened, the distance between the measurement unit 50 and the lamp body 101 is generally shortened. For this reason, dust adheres more easily to the detection surface 50a.

  In this case, the attached dust can be removed by cleaning the detection surface 50a each time the lamp body 101 is cleaned or every certain period. However, in general, there are a large number of aerial beacon lamps 100 to be cleaned in one cleaning operation. For this reason, if the process of cleaning the detection surface 50a is provided in the process of the cleaning operation, the time of the cleaning operation becomes longer correspondingly, and there is a possibility that the time zone during which the guideway or the like cannot be used may be expanded.

  In the lamp cleaning device 1 according to the present embodiment, since the measurement unit 50 is moved to the retracted position when cleaning is performed, it is possible to suppress dust from adhering to the detection surface 50a. Therefore, the number of times of cleaning the detection surface 50a can be significantly reduced. As a result, the cleaning operation time can be substantially shortened. Note that when the cleaning is performed, the measurement by the measurement unit 50 is not performed. Therefore, even if the measurement unit 50 is moved to the retracted position when performing cleaning, there is no influence on the measurement process.

The retreat position is not particularly limited as long as dust adhesion can be suppressed. In this case, as shown in FIG. 3, if the detection surface 50 a of the measurement unit 50 faces in the direction opposite to the discharge port of the nozzle 41, it becomes easy to suppress the adhesion of dust.
In addition, it is preferable that a member facing the detection surface 50a is provided at the retracted position. In the case of the example illustrated in FIG. 3, the wall surface of the distal end portion of the moving unit 42 faces the detection surface 50 a. Note that the facing member is not limited to the moving unit 42. For example, a plate-like member may be provided in the moving part 42.
If a member facing the detection surface 50a is provided, it becomes easier to suppress the adhesion of dust.
As described above, the holding unit 42b can change the direction in which the measurement unit 50 faces in a direction different from the direction in which the nozzle 41 faces.
When the cleaning material supply unit 20 supplies the cleaning material to the nozzle 41, the holding unit 42b changes the direction in which the measurement unit 50 faces in a direction different from the direction in which the nozzle 41 faces.
When the measurement unit 50 measures the light emitted from the lamp body 101, the holding unit 42 b directs the measurement unit 50 in the direction of the lamp body 101. In this case, the cleaning material supply unit 20 does not supply the cleaning material to the nozzle 41.

In addition, it can also be set as the structure which a measurement part does not move. For example, an open / close mechanism that can arbitrarily protect the front of the measurement unit (for example, an open / close mechanism such as a shutter that can cover or open the light incident surface of the measurement unit) can be provided, and dust or the like can adhere to the measurement unit In order to prevent this, a mechanism such as an air shutter that blows high-pressure air onto the measurement unit can be provided. That is, it is only necessary to provide a means for protecting the measurement function in the measurement unit from being hindered by washing.
In addition, when the measurement unit does not move, the holding unit 42 b can be fixed to the tip portion of the moving unit 42. If the measurement unit does not move, it becomes easy to measure the direct light emitted from the lamp body 101. In addition, it becomes easy for the measurement unit to have a configuration in which light from the lamp body 101 is reflected and measured.

As described above, it is only necessary to provide an adhering matter suppressing unit that suppresses the measurement function of the measuring unit 50 from being hindered by adhesion of external dirt.
For example, the adhering matter suppressing unit may be a holding unit 42b, the opening / closing mechanism described above, a mechanism such as an air shutter, or the like.
In the case where the adhering matter suppressing unit is the holding unit 42b, the adhering matter suppressing unit (holding unit 42b) can hold the measuring unit 50. The adhering matter suppressing unit (holding unit 42b) can change the direction in which the measuring unit 50 faces in a direction different from the direction in which the nozzle 41 faces. The adhering matter suppressing portion (holding portion 42b) can be rotatably provided on the moving portion 42.
When the cleaning material supply unit 20 supplies the cleaning material to the nozzle 41, the adhering matter suppressing unit (holding unit 42b) changes the direction in which the measurement unit 50 faces to a direction different from the direction in which the nozzle 41 faces. Can do.
When the measurement unit 50 measures the light emitted from the lamp body 101, the adhering matter suppressing section (holding section 42 b) can point the measurement section 50 in the direction of the lamp body 101. In this case, the cleaning material supply unit 20 can prevent the cleaning material from being supplied to the nozzle 41.

As shown in FIGS. 1 and 2, the photographing unit 60 is electrically connected to the control unit 70. The imaging unit 60 captures an image of the lamp 101 and converts the captured image data into an electrical signal. The image data converted into the electrical signal is input to the control unit 70. The imaging unit 60 can be, for example, a CCD image sensor.
The photographing unit 60 can be provided at a position where the lamp body 101 can be photographed. For example, as shown in FIG. 1, the photographing unit 60 can be provided in a region of the inner wall of the cover 12 located above the opening 11a. However, the position where the imaging unit 60 is provided is not limited to this. For example, the imaging unit 60 can be provided in the peripheral area of the opening 11 a on the back surface of the loading platform 11.

In addition, the photographing unit 60 can be provided at the distal end portion of the moving unit 42. If the photographing unit 60 is provided at the distal end portion of the moving unit 42, the photographing unit 60 can be brought close to the lamp 101, so that the lamp 101 can be easily photographed.
In this case, the imaging unit 60 can be held by the holding unit 42b. The imaging unit 60 can be held side by side with the measurement unit 50. If the imaging unit 60 is held by the holding unit 42b, the imaging unit 60 can be moved to the retracted position when cleaning is performed. For this reason, it is possible to prevent dust from adhering to the incident surface of the imaging unit 60, and thus it is possible to greatly reduce the number of times the incident surface is cleaned. As a result, the cleaning operation time can be substantially shortened. Note that when the cleaning is performed, the imaging unit 60 does not perform imaging. For this reason, even if the photographing unit 60 is moved to the retracted position when performing the cleaning, there is no influence on the photographing process.
The retracted position and the member provided at the retracted position and facing the incident surface of the imaging unit 60 can be the same as those of the measurement unit 50 described above.
In addition to the holding unit 42b, the photographing unit 60 may be held by a holding unit that is rotatably provided at the distal end portion of the moving unit 42. However, if the holding unit 42b holds the measurement unit 50 and the imaging unit 60, the configuration of the distal end portion of the moving unit 42 can be simplified.

As will be described later, the photographing unit 60 is provided to detect the position of the lamp body 101. Therefore, if the position of the lamp 101 can be detected by measuring the light emitted from the lamp 101 by the measuring unit 50, the photographing unit 60 can be omitted. However, if the photographing unit 60 is provided, the position of the lamp body 101 can be detected with high accuracy.
Moreover, the imaging | photography part 60 can also be provided in one place and can also be provided in several places.

  The control unit 70 controls the operation of each element provided in the lamp cleaning device 1. Further, the control unit 70 can determine whether or not the cleaning is necessary based on the value measured by the measuring unit 50 and can determine whether or not the cleaning result is good.

For example, the control unit 70 can determine that the cleaning is necessary when the value measured before the lamp body 101 is cleaned is less than a predetermined threshold value. Moreover, the control part 70 can determine with washing | cleaning being unnecessary, when the measured value is more than a predetermined threshold value. Note that all the lamps 101 may be cleaned without performing measurement before cleaning. However, if the necessity of cleaning is determined, the total time of the cleaning operation can be shortened.
For example, the control unit 70 can end the cleaning operation when the value measured after the lamp body 101 is cleaned is equal to or greater than a predetermined threshold value. Moreover, the control part 70 can wash again, when the value measured after washing | cleaning of the lamp 101 is less than a predetermined threshold value. When the number of re-cleaning exceeds a predetermined threshold, it can be determined that an abnormality has occurred in the lamp body 101.

The control unit 70 can be, for example, a computer including a CPU (Central Processing Unit) and a storage device. The storage device can be, for example, a semiconductor memory or a hard disk drive. The storage device can store an operation program for each element provided in the lamp body cleaning apparatus 1, cleaning conditions such as the discharge pressure and cleaning time of the cleaning material, information on the road surface 102 and the lamp body 101, and the like. The CPU controls the operation of each element provided in the lamp cleaning device 1 based on the operation program stored in the storage device, cleaning conditions, information on the road surface 102 and the lamp 101, and the like. The CPU can also determine whether or not cleaning is necessary and whether or not the cleaning result is good.
Moreover, the control part 70 can further have a function of a switchboard. For example, the control unit 70 may have a connection terminal, a switch, and the like.

(Lamp cleaning method)
The driver of the vehicle 10 moves the vehicle 10 to the vicinity of the lamp body 101 to be cleaned. At this time, the driver can adjust the position of the vehicle 10 based on the image of the lamp 101 captured by the photographing unit 60 and displayed on the display unit 13. For example, the driver moves the vehicle 10 so that the image of the lamp body 101 falls within a predetermined area displayed on the display unit 13.
When the vehicle 10 is an autonomous driving vehicle, the control unit 70 drives the vehicle 10. A known technique can be applied to the driving program for the vehicle 10.

  Next, the control unit 70 detects the position of the lamp body 101 by at least one of the imaging unit 60 and the measurement unit 50. For example, the control unit 70 detects the position of the lamp 101 based on the image of the lamp 101 photographed by the photographing unit 60, and thus the position of a light projection window, a lens, and the like. The detection based on the image of the lamp 101 can be performed by, for example, a known image processing program. For example, the control unit 70 detects the positions of the light projection window and the lens based on the light intensity measured by the measurement unit 50. For example, the control unit 70 detects a region with a high luminous intensity as a light projection window or a lens.

Next, the control unit 70 determines whether or not cleaning is necessary based on the value measured by the measurement unit 50. The control unit 70 can display the determination result on the display unit 13.
The driver who has confirmed that the cleaning is unnecessary moves the vehicle to the vicinity of the next lamp body 101. When the vehicle 10 is an autonomous driving vehicle, the control unit 70 moves the vehicle to the vicinity of the next lamp body 101.
When it is determined that the cleaning is necessary, the control unit 70 performs the cleaning illustrated below. Note that all the lamps 101 may be cleaned without determining whether or not cleaning is necessary. However, if the necessity of cleaning is determined, the total time of the cleaning operation can be shortened.

When performing the cleaning operation, the control unit 70 controls the moving unit 42 to move the nozzle 41 in the vicinity of the detected light projection window or lens.
Further, the control unit 70 controls the holding unit 42b to move the measuring unit 50 to the retracted position. When the imaging unit 60 is provided in the holding unit 42b, the control unit 70 controls the holding unit 42b to move the imaging unit 60 to the retracted position.

Next, the control unit 70 controls the cleaning material supply unit 20 to discharge the cleaning material from the nozzle 41. For example, the control unit 70 stops the discharge of the cleaning material after a predetermined time has elapsed.
Next, the control unit 70 controls the holding unit 42b to move the measurement unit 50 from the retracted position to the vicinity of the light projection window or the lens.
Next, the control unit 70 determines the quality of the cleaning result based on the value measured by the measurement unit 50.
When it is determined that the cleaning result is good, the control unit 70 displays the determination result on the display unit 13. The driver who has confirmed the determination result moves the vehicle to the vicinity of the next lamp body 101. And the washing | cleaning operation | work of said procedure is performed. When the vehicle 10 is an autonomous driving vehicle, the control unit 70 moves the vehicle to the vicinity of the next lamp body 101.
When it is determined that the cleaning result is defective, the control unit 70 can perform the above cleaning again. In addition, when the number of times of re-cleaning exceeds a predetermined threshold, the control unit 70 can also determine that an abnormality has occurred in the lamp body 101.

As described above, the lamp cleaning method according to the present embodiment can include the following steps.
A step of suppressing the measurement function of the measurement unit 50 capable of measuring light emitted from the lamp body 101 from being disturbed by the measurement section 50 becoming dirty when the lamp body 101 is cleaned.
A step of discharging the cleaning material from the nozzle 41 toward the lamp body 101.
In this case, in the step of suppressing the measurement function of the measurement unit 50 from being disturbed, the direction in which the measurement unit 50 faces can be changed to a direction different from the direction in which the nozzle 41 faces.
In addition, the method may further include a step of directing the measurement unit 50 in the direction of the lamp body 101 supplied with the cleaning material and measuring light emitted from the lamp body 101 supplied with the cleaning material.
Moreover, the process which measures the light radiate | emitted from the lamp 101 before a cleaning material is supplied by the measurement part 50 can be further provided.
In addition, since the content in each process can be the same as that of what was mentioned above, detailed description is abbreviate | omitted.
In the present embodiment, the process of determining whether or not cleaning is necessary based on the value measured by the measurement unit 50 has been described. However, it is not necessary to determine whether or not cleaning is necessary, and cleaning of the lamp body 101 is essential. Therefore, the measurement by the measurement unit 50 may be performed for confirming the cleaning effect. In this case, the difference from the above process is that the control unit 70 does not indicate the determination result of necessity of cleaning before cleaning. Other than that, the cleaning effect can be confirmed by substantially the same process. The confirmation of the cleaning effect can be an additional element of the cleaning function. That is, the confirmation of the cleaning effect may not necessarily be performed after the cleaning, and the cleaning effect may be confirmed with an arbitrary intention of the user.
