Description

  The present invention relates to a discharge lamp, and more particularly, to a discharge lamp including an IC tag that holds information for safely lighting while preventing erroneous mounting and explosion.

  A short arc type discharge lamp is used as a light source of an exposure apparatus that forms a pattern on a semiconductor, a liquid crystal panel, a printed wiring board, or the like. There is also a short arc type discharge lamp in which a rare gas such as Xe gas, Kr gas, or Ar gas is sealed in an arc tube at 1 atmosphere or more at room temperature. In addition, in a metal vapor discharge lamp such as a rare gas discharge lamp or a mercury discharge lamp used as a light source for a projector or a projector, there is a discharge lamp in which a rare gas of 1 atm or more is enclosed in an arc tube. Hereinafter, these high-pressure gas-filled discharge lamps are simply referred to as discharge lamps or discharge lamps.

  When a discharge lamp is transported or attached to a device that lights the discharge lamp, if the discharge lamp is accidentally subjected to a large impact, the discharge lamp may be damaged. In particular, when a high-pressure gas-sealed discharge lamp is broken, the impact of high-pressure gas discharge is great, which can be life-threatening. Even if it does not lead to breakage, if a small scratch or crack occurs due to the impact, or if a part of the device part peels off and remains on the surface, the discharge lamp may burst during lighting. In order to avoid such a problem, a safety cover is attached with a string to mitigate an impact when the discharge lamp is ruptured during an operation of attaching the discharge lamp to the lighting device. Further, in order to prevent forgetting to remove the protective cover, a resistance circuit and a capacitor circuit are provided on the protective cover so that the lighting device can recognize the presence of the protective cover. The following are some examples of the related art.

  The “safety cover for a discharge lamp” disclosed in Patent Document 1 reduces damage caused when a discharge lamp filled with a high-pressure rare gas bursts. As shown in FIG. 8A, a discharge lamp in which a gas body having a pressure higher than atmospheric pressure is sealed at room temperature is protected. It is a cover formed of a breathable sheet, a breathable cylinder, and a breathable bag. The end of this cover is bound to the stem portion of the discharge lamp or bound outside the base portion.

  The “protective cover for discharge lamp” disclosed in Patent Document 2 can easily attach the protective cover to the discharge lamp, and the protective cover can be removed even after the discharge lamp is attached to the lighting device. This is a protective cover for a discharge lamp that can be easily performed. As shown in FIG. 8B, a self-adhesive sheet was used for the discharge lamp protective cover that covers at least the arc tube portion of the discharge lamp.

  The “discharge lamp protective cover” disclosed in Patent Document 3 prevents forgetting to remove the discharge lamp protective cover that is covered to protect the discharge lamp after the discharge lamp is attached to the discharge lamp lighting device. Is. As shown in FIG. 8C, a resistance circuit or a capacitor circuit connected between both terminals or both caps of the discharge lamp is provided on the discharge lamp protective cover for covering the discharge lamp. As a result, if you forget to remove the discharge lamp protection cover after attaching the discharge lamp to the discharge lamp lighting device, the discharge lamp will not light even if you try to turn on the discharge lamp. Forgetting can be prevented.

  The “ultra-high-pressure mercury lamp” disclosed in Patent Document 4 is used even when the discharge lamp ruptures when excessive stress exceeding a specified level is applied during lamp replacement work or when there is a malfunction in the discharge lamp. It is an ultra-high pressure mercury lamp that does not scatter debris. The ultra-high pressure mercury lamp is used as a light source in a semiconductor exposure apparatus or the like in which a gas at atmospheric pressure or higher is enclosed. As shown in FIG. 8 (d), the protective cover that wraps the bulb and the protective case that is packed during transportation are covered twice until the ultrahigh pressure mercury lamp is fixed to the lighting device. After fixing the ultra-high pressure mercury lamp to the lighting device, it is easy to check the presence of the protective cover. The lamp cannot be lit without removing the protective cover.

  The “inkjet printer” disclosed in Patent Document 5 directly uses a non-contact type or contact type IC tag semiconductor memory in which a password, light source usage history, light source shipment information, and the like are recorded, as a light source for irradiating ultraviolet rays. Or, it is provided in the connector and wiring to prevent the use of different types of light sources, and the lifespan is managed by writing the lighting time and the number of lighting-off times on the IC tag.

  The “consumables replacement time management system” disclosed in Patent Document 6 is provided with an IC tag having information such as ID information, seal opening state information, use start time information, fluorescent lamp wattage, and the like on a consumable chip. Thus, the replacement time of consumables is automatically managed.

The “discharge lamp protective cover” disclosed in Patent Document 7 prevents mistaken mounting of the discharge lamp and forgetting to remove the protective cover. As shown in FIG. 8E, the surface of the discharge lamp is protected by a protective cover so that damage can be reduced even when the discharge lamp filled with high-pressure gas is ruptured during transportation. An IC chip is provided on the protective cover to hold information on the discharge lamp. When attaching the protective cover to the lighting device, reading the information on the IC chip prevents incorrect installation of the discharge lamp. When the protective cover is removed, the IC chip is destroyed, so that the information on the IC chip cannot be read, the removal of the protective cover is detected, and forgetting to remove can be prevented. By authenticating the discharge lamps individually, the specifications of the discharge lamps are checked as appropriate, and the occurrence of defects after the operation of the apparatus by lighting the discharge lamps with different specifications is prevented.

  However, conventional discharge lamp protective covers and IC tags have the following problems. By simply providing an IC chip on the arc tube cover that can be removed from the discharge lamp, individual discharge lamp management cannot be performed. Since it is impossible to grasp the storage state and the transportation state of the discharge lamp, it is impossible to know the damage of the discharge lamp. If the IC tag is attached directly to the discharge lamp, the IC tag will be destroyed by high heat and high voltage during lighting. Since the lighting state cannot be recorded, the life of the discharge lamp cannot be managed. Even if the IC tag is attached to the discharge lamp through a heat insulating material by a simple method, the shape will be different from the normal one, so it cannot be used unless it is a dedicated lighting device.

  Inappropriate transport conditions include, for example, abnormal shocks and temperatures. With respect to the impact, if the impact is such that the arc tube breaks, the discharge lamp is not kept airtight and cannot be lit, so it is not used in the light source device. On the other hand, when the arc tube is subjected to such an impact as not to break down, there is a case where it is lit in a cracked state when the damage is inconspicuous. If it lights up with a crack in this way, the crack will start from the crack. For abnormal temperatures, the discharge lamp is stored at an abnormally high temperature, and the arc tube cover sticks to the surface of the arc tube. Even after the arc tube cover is removed, the minute lamps that make up the arc tube cover Fragments remain on the arc tube surface.

  Further, since the discharge lamp is stored at an abnormally low temperature, water vapor in the air condenses or freezes on the surface of the arc tube, so that minute water droplet stains remain in the light emitting portion. If the discharge lamp is turned on with a small piece of arc tube cover or a minute water droplet stain on the surface of the arc tube, the fragment or stain may become hot and the discharge lamp may burst. . Thus, since it is difficult to determine whether or not the discharge lamp is in a ruptured state at first glance, in most cases, the lamp is lit as it is, leading to a rupture.

  In order to start lighting the discharge lamp, a high voltage starter pulse is temporarily applied between the electrodes in the discharge lamp to cause dielectric breakdown. Thereafter, a method of lighting with a normal voltage is taken. Therefore, if the IC tag is directly attached to the discharge lamp, the internal circuit of the IC tag is destroyed. Further, since the discharge lamp is in a high temperature state during lighting, if the IC tag is directly attached to the discharge lamp, the internal circuit of the IC tag is destroyed at a high temperature. Also, in order to protect the discharge lamp in the packaging box, a packaging box that is significantly larger than the discharge lamp is usually used. Therefore, it is difficult for the conventional lamp packaging box to read and write information on the IC tag with the discharge lamp in the packaging box.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems, and to strictly control individual information with an IC tag in a discharge lamp so that it can be lit safely.

  In order to solve the above-described problems, in the present invention, an insulating member is provided on a power supply line of a discharge lamp including a light emitting tube, a pair of electrodes facing each other in the light emitting tube, and a power feeding structure that supplies power to the electrodes. It was set as the structure provided with the IC tag bent and held through. The insulating member is a flexible member that is coupled onto a power supply line adjacent to the power supply terminal of the power supply structure. The insulating member is a tag holder that includes a tag holding portion that holds the IC tag inside, a coupling portion that is fixed to the power supply line, and a small-diameter portion that flexibly connects the coupling portion and the tag holding portion. . A shield member is provided that covers the IC tag in a shape that shields heat and electrical noise from the IC tag during lighting and does not block radio waves that read and write information to the IC tag. Information on one of lamp information, transportation information, unsealing history information, lighting history information, or a combination thereof is recorded on the IC tag.

  Lamp information includes date of manufacture, manufacturer name, manufacturing location, manufacturing line, lamp model, model number, lot number, identification number, rated lamp current, rated lamp voltage, cooling conditions, installation direction on the device, and usage limit Information of time or a combination of these, and transportation information includes factory shipment date / time, warehouse receipt / shipment date / time, agency arrival / shipment date / time, shipping destination, shipping company name, package slip number, person in charge name , Temperature history, shock history, or a combination of these. Opening history information is either the date / time when the packaging box was opened, the date / time when the arc tube cover was opened, or a combination of these. The lighting history information includes lighting start date / time, extinguishing date / time, relighting date / time, lighting condition, number of blinks, integrated lighting time, device individual number, device setting, device error information, use prohibition information. Either, or is information for these combinations.

  In a light source device using this discharge lamp, an IC tag reader is disposed at a position facing an IC tag provided on the discharge lamp. Means for determining whether the lamp can be lit based on the lamp information in the IC tag read by the IC tag reader, the transport information, the opening history information, and the lighting history information, and if it is determined that the lamp cannot be lit, the discharge lamp And means for controlling so that it cannot be used normally. Means for writing lighting history information to the IC tag is provided. When an error occurs in communication between the IC tag and the reading device, there is provided means for controlling so that the discharge lamp can be lit only for a certain period.

  With the configuration described above, the individual information can be strictly managed by the IC tag and can be lit safely. In particular, since the IC tag is provided on the tag holder attached to the power supply line of the discharge lamp, it is possible to manage the transport history and lamp usage history of each discharge lamp. That is, by recording the discharge lamp transport information on the IC tag, it is possible to prevent the use of a discharge lamp that is highly likely to burst due to improper transport. Since the insulating tag and shield member protect the IC tag from high heat and noise signals, information can be read and written even while the lamp is lit, and discharge lamp usage information can be recorded on the IC tag and managed accurately. Furthermore, since the IC tag is provided at a site where there is no problem even if it is attached to the conventional light source device, it can be turned on with the conventional light source device.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS.

The packaging box is provided with a transport environment sensor, a packaging sensor, a control unit that is electrically connected to and controlled by these sensors, and a cover sensor. The control unit and the arc tube cover sensor are electrically connected to the terminal part of the IC tag 40. Since the control unit has a clock and outputs time information indicating the current time, the time information can be added to the transportation environment information and the opening history information.

  FIG. 5 is a diagram showing when information is written to the IC tag and its contents. FIG. 6 is a diagram in which an IC tag is attached to a straight tube type discharge lamp. In FIG. 6, a lamp 101 is a high-pressure mercury lamp. The arc tube 102 is a straight tube made of quartz.

The base 204 is a part that receives electric power from the outside and holds the discharge lamp in the light source device.

  The function and operation of the discharge lamp in the embodiment of the present invention configured as described above will be described. First, the outline of the function of the discharge lamp will be described with reference to FIG. A method of holding the IC tag 40 on the feeder line 7 is as follows. A power supply line 7 for supplying power to the lamp 1 is drawn from the base 4. A crimp terminal 8 is fixed to the end of the feeder line 7. The coupling portion 46 of the tag holder is coupled to the feeder 7 near the crimp terminal 8. A tag holding unit 44 is coupled to the coupling unit 46 via a small diameter unit 45. The tag holding unit 44 holds the IC tag 40 surrounded by the shield unit 47. A reader / writer 60 is provided at a position close to the IC tag 40 and reads information relating to the lamp 1 and information relating to transportation held by the IC tag 40. The lamp 1 is thus attached to the light source device and turned on.

  Next, a method for attaching the IC tag to the light source device will be described with reference to FIG. An IC tag 40 is attached to the feeder line 7 at a position close to the crimp terminal 8 so as to move freely. When the tag fixing screw 55 is passed through a hole (not shown) of the tag holding portion 44 and fixed to the tag fixing base 54, the IC tag 40 and the reader / writer 60 are held so as to face each other. The IC tag 40 is held by the tag holder 43 so as to move freely within a certain range from the feeder line 7 at a position close to the crimp terminal 8. Therefore, the relative positional relationship between the power supply terminal 52 and the reader / writer 60 can be freely set.

  Next, the packaging state of the discharge lamp will be described with reference to FIG. The lamp 1 is transported while being protected from external force by a packaging box 20 including an exterior part 21 and a buffer part 22. In order to prevent external force from being transmitted to the lamp 1, the lamp 1 is held in the packing box 20 by the buffer portion 22 so that a certain distance is maintained between the lamp 1 and the exterior portion 21. . Here, the buffer portion 22 uses a tray of PET material that is press-molded into a shape having a buffer function. In general, when reading / writing from / to the small IC tag 40, it is necessary to bring the reader / writer 60 close to the IC tag 40 to several millimeters. Since the IC tag 40 can be brought close to the exterior portion 21 of the packaging box 20 by the power supply line 7 and the tag holder 43, the reader / writer 60 can approach the IC tag 40 without providing a recess in the packaging box 20. . Therefore, even when the lamp 1 is in the packaging box, information can be easily read and written (communication) with respect to the IC tag 40.

  Next, operations of the IC tag and the reader / writer will be described with reference to FIG. During the manufacture of the discharge lamp and during the transportation process, the reader / writer 60 writes the lamp information and the transportation information. Here, the actual discharge lamp and the information written in the IC tag 40 are collated. In the light source device in which the discharge lamp is used, the system unit reads and writes information in the storage device of the IC tag 40 via the reader / writer 60. In consideration of the result and the information in the storage device of the light source device, it is determined whether or not the discharge lamp can be used. In response to the result, a warning display and necessary operations are performed in the light source device.

  Information written to the IC tag 40 includes lamp information, transportation information, opening history information, and lighting history information. Below, these information is demonstrated. The lamp information includes individual lamp information and device setting information. The individual lamp information includes a manufacturing date, a manufacturer name, a manufacturing place, a manufacturing line, a lamp model, a product number, a lot number, an identification number, and the like. The device setting information includes a rated lamp current, a rated lamp voltage, a cooling condition, an installation direction to the device, a use limit time, and the like. The transportation information includes transportation progress information and transportation state information. The transportation progress information includes factory shipment date / time, warehouse entry / exit date / time, agency arrival / shipment date / time, ship-to party (customer), transport company name, package slip number, person in charge name, and the like. The transportation state information includes a temperature history and an impact history. As a method for leaving the temperature history, for example, there is the following method. When the temperature sensor detects that the temperature has exceeded the specified temperature or below the specified temperature for a certain period of time, information indicating that it has been stored in an abnormal state and the temperature value at that time are stored in the IC tag 40. Record. As a method of leaving an impact history, for example, there is the following method. When it is detected by an acceleration sensor or the like that an impact of a certain value or more has been detected, information indicating that an abnormal impact has been received and the acceleration value at that time are recorded in the IC tag 40. Furthermore, the time information of the control unit may be added and recorded in the IC tag 40.

  The opening history information is information such as a history of opening the packaging box 20 and a history of opening the arc tube cover. When the packaging box 20 is opened or when the arc tube cover is opened, each opening history information is recorded in the IC tag 40. As a method for detecting opening, for example, there is the following method. A sensor is used in which a part of the circuit is opened by peeling off the conductive seal. When the packaging box 20 is opened, the opening history information that the packaging box 20 has been opened is written in the IC tag based on the signal of the packaging box sensor connected to the terminal portion of the IC tag 40 via the control unit. Furthermore, the time information of the sensor control unit may be added and recorded on the IC tag. When the arc tube cover is opened and removed from the discharge lamp, the packaging box 20 is separated from the discharge lamp. Therefore, the opening history information that the arc tube cover has been removed is written based on the signal of the cover sensor connected to the terminal portion of the IC tag 40 without going through the sensor control unit. When the IC tag 40 is not equipped with a power supply, the connection with the cover sensor is later detected by the reader / writer 60 via the terminal portion.

  The lighting history information includes lighting start date / time, extinguishing date / time, relighting date / time, lighting condition, number of blinks, integrated lighting time, device individual number, device setting, device error information, use prohibition information, and the like. These pieces of information can be used not only for managing the usage status of the discharge lamp but also for investigating the cause later when a malfunction occurs in the discharge lamp.

  Next, with reference to FIG. 5, a description will be given of the case of writing information to the IC tag and the content thereof. Write lamp information to the IC tag using a reader / writer when manufacturing the lamp. When the lamp is transported, the transport progress information is written to the IC tag using a reader / writer. Here, the lamp information written in the IC tag is read, and the discharge lamp and the lamp information are collated. When temperature and impact become abnormal during transportation, transportation status information is written to the IC tag. By opening the packing box, packing box opening history information is written to the IC tag. By removing the arc tube cover from the discharge lamp, arc tube cover removal information is written to the IC tag.

  When the lamp is mounted on the light source device, before the light source device turns on the lamp, the lamp information, transportation information, opening history information, and lighting history information written on the IC tag are read to determine whether the lamp can be lit. Display and stop lighting operation. If the lamp information reveals that the lamp type is incompatible with the light source device, the light source device issues a warning. For transportation information, for example, the following determination is made. If the period from the lamp manufacturing time to the lighting start time is abnormally long, the lamp performance cannot be secured, and the light source device issues a warning. When the period from the time when the packaging box is opened to the lighting start time is abnormally long, the storage condition of the lamp is suspected, and the light source device issues a warning. If there is no record of opening the arc tube cover, the light source device issues a warning because it is suspected that the arc tube cover is forgotten to be removed.

  If there is a record of abnormality in the temperature history or impact history, the light source device issues a warning. It is preferable that the light source device not only gives a warning to the worker but also prevents the discharge lamp from being used forcibly. In the light source device, the following lighting history information is written while the discharge lamp is used. When the discharge lamp starts lighting, the lighting start date and time and lighting conditions are written in the IC tag. Write the lighting time and lighting conditions to the IC tag even after lighting for the specified time. Further, when the lighting time exceeds the life of the discharge lamp, a warning is issued to the worker or the lamp is forcibly turned off.

  When the discharge lamp is turned off, the lighting time and date and time of turning off are written in the IC tag. When the system unit of the light source device determines that the lighting state of the discharge lamp is abnormal, after the discharge lamp is forcibly turned off, the abnormal state and the date and time of occurrence are recorded in the IC tag as lighting history information. Write. The recording of the abnormal state may be an error code of the apparatus. In the case of a lamp abnormality that cannot be relighted, lighting history information indicating that use has been prohibited is written to the IC tag. Even when the discharge lamp is turned on again, before the light source device turns on the discharge lamp, the lamp information, transportation information, opening history information, and lighting history information written in the IC tag are read to determine whether the lamp can be lit. . For this reason, even when the discharge lamp is changed during its life, the usage history such as the lighting time remains as a record in the IC tag of the lamp body, so that the life of the discharge lamp can be individually managed.

  In the discharge lamp that has reached the specified life, lighting history information that the use is prohibited because the specified life has been reached is written in the IC tag. Further, if the discharge lamp is an abnormal discharge lamp and cannot be lit again, lighting history information indicating that the use is prohibited is written in the IC tag in the discharge lamp determined by the system of the light source device. Since the discharge lamp provided with the IC tag in which the use prohibition information is written is rejected to be turned on by determining whether the light source device can be turned on or not, it can be prevented from being turned on by mistake. Furthermore, in the light source device, the lamp information may be read from the IC tag and recorded in the storage device as a discharge lamp whose use has been stopped. When the IC tag is recovered from the discharge lamp that has been stopped, the usage status of the discharge lamp can be grasped from the lighting history information of the IC tag, which can be used for future lamp quality control. Moreover, when the lighting is stopped due to a lamp abnormality, it can be used for investigating the cause.

  When a communication error occurs between the IC tag and the reading device during initial lighting, relighting, or lighting, it is preferable to take measures to enable the discharge lamp to be lit only for a certain period. In the case of a communication error at the time of initial lighting or relighting, the lamp can be lit for a certain period by an operator inputting lamp information such as the manufacturing number of the discharge lamp from the touch panel of the light source device. . The lamp information such as the input manufacturing number is recorded in the storage device of the light source device, whereby the lamp lighting time can be managed. In the case of a communication error while the lamp is lit, the lamp can be lit continuously for a certain period. Even in this case, when a problem occurs in the lamp itself, it is preferable to forcibly turn off the light source device. Since the lighting period is a temporary measure until the maintenance staff arrives for repair of the IC tag reader, the certain period is, for example, a period of several days. Particularly in a remote place, it is preferable to set the period longer.

  Next, an example in which an IC tag is attached to a straight tube type discharge lamp will be described with reference to FIG. Examples of the straight tube type discharge lamp include a high-pressure mercury lamp, a metal halide lamp, and a low-pressure mercury lamp, but are not limited to these discharge lamps. A base 104 is fixed to an end portion of the sealing tube 103 provided continuously with the arc tube 102. The lamp 101 is held in the light source device via the base 104. A power supply line 7 extends from the base 104. One end of the feeder line 7 is electrically connected to an electrode (not shown) in the arc tube. A crimp terminal 8 is fixed to the other end. The IC tag 40 covered with the shield portion 47 is coupled to the feeder line 7 by the tag holder 43 while being electrically insulated from the outside.

  Next, an example of attaching an IC tag to a U-shaped discharge lamp will be described with reference to FIG. Examples of the U-shaped discharge lamp include a low-pressure mercury lamp, a cold cathode lamp, and a flash lamp, but are not limited to these discharge lamps. A base 204 is fixed to both ends of the arc tube 202. The lamp 201 is held in the light source device via the base 204. A power supply line 7 extends from the base 204. One end of the feeder line 7 is electrically connected to an electrode (not shown) in the arc tube. A connector 9 is fixed to the other end. The IC tag 40 covered with the shield portion 47 is coupled to the feeder line 7 by the tag holder 43 while being electrically insulated from the outside.

  These discharge lamps can also protect the IC tag from a high voltage at the start of lighting and a high temperature during lighting. The IC tag is directly attached to the discharge lamp, and individual information on the discharge lamp is managed. Furthermore, when the discharge lamp has a possibility of bursting or the like due to an inappropriate transportation state, the discharge lamp can be prevented from being turned on.

  As described above, in the embodiments of the present invention, the discharge lamp is provided with an IC tag that holds information on the discharge lamp, information on transportation, and information on lighting on a tag holder that is bent and attached to a power supply line, and heat during lighting Since it is configured to cover the electrical noise and shield the radio waves for communication, the individual discharge lamps are used throughout the entire process from production to use, including during storage and transportation and lighting. Information can be managed and it can always be turned on safely.

  The discharge lamp of the present invention is optimal as a discharge lamp that can be safely operated by strictly managing compatibility and history. In particular, it is indispensable as a discharge lamp for applications in which a discharge lamp that is at risk of bursting due to improper transportation and management cannot be lit.

It is the figure which provided the IC tag in the state which moved freely to the electric power feeding line of the discharge lamp in the Example of this invention.
