BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light source device, and more particularly, to a light source device for mounting and lighting a plurality of discharge lamps in parallel to manage lamp information with an IC chip.

Conventionally, low pressure mercury lamps are used for various purposes. Low-pressure mercury lamps, which mainly emit two types of short wavelength ultraviolet rays of 185 nm and 254 nm or one type of 254 nm, are used for various photochemical reactions, surface modification, sterilization, and the like. As an example of the conventional low pressure mercury lamp, the low pressure mercury lamp disclosed by patent document 1 is mentioned. In recent years, excimer lamps using light emitted from excimer molecules have also been used. As an example of the conventional excimer lamp, there is an excimer lamp device disclosed in Patent Document 2. These lamps may be used for thousands of hours. In the light source apparatus, a plurality of lamps are collectively managed for life by resetting the lighting time and resetting the lighting time with lamp replacement. There is also a method in which an operator appropriately recognizes the time to replace the discharge lamp by installing an IC chip in the discharge lamp and installing a read / write device in the light source device to read the information recorded on the IC chip, and managing the lighting time of the discharge lamp. Some examples of the related art related to this are given below.

The "low pressure mercury lamp" disclosed in Patent Document 1 facilitates maintenance at low cost by controlling the temperature of the lowest portion of the light emitting tube and maintaining the mercury vapor pressure at a predetermined value. As shown in Fig. 7A, both ends of the light emitting tube of the U-shaped valve include a cathode and an anode. The electrode portion is fixed with a metal block and a metal plate. The temperature of the lowest part of a light emitting tube is maintained at 40 degreeC by blowing the temperature-regulated gas from a gas temperature control apparatus to an electrode rear part.

The "excimer lamp apparatus" disclosed in Patent Literature 2 is provided with a seam which prevents the leakage of the cooling medium and prevents damage caused by external force. As shown in Fig. 7 (b), the discharge space is formed by the external appearance and the inner tube of the cylindrical shape arranged on the same axis. Electrodes are arranged on both sides of the discharge space. Cooling medium flows through the cooling medium conduit in the inner space formed by the inner tube. By arranging several or several dozen low pressure mercury lamps and excimer lamps in parallel, the large area can be irradiated.

The light source lamp unit disclosed in Patent Document 3 is such that the reflective surface portion of the reflecting mirror does not deform. As shown in Fig. 7C, the lamp information carrying section carries type information of the light source lamp. The lamp type is detected on the light source device side of the optical apparatus to which the light source lamp unit is mounted. According to the lamp type, the light source lamp unit can be turned on and driven in an optimum control mode. Compatible light cooling lamp units of different types can be attached to the same light source device.

The dimming system disclosed in Patent Document 4 announces the monitoring information and the instrument information such as the accurate cumulative lighting time of each lighting fixture connected to the dimmer. As shown in Fig. 7D, the lighting fixture is equipped with an RFID tag having an identification number. The dimmer is equipped with an RFID tag having an identification number, performs dimming control of the luminaire, and transmits a dimming control state. The RFID reading device reads form-specific numbers in pairs from RFID tags of lighting fixtures and dimmers. The dimmer controller controls the driving of the dimmer and creates a database showing the monitoring contents of each luminaire based on the pair identification numbers of the luminaire and the dimmer.

The consumable replacement time management system disclosed in Patent Document 5 manages the use start time and elapsed time of use of consumables, and automatically notifies the user when the replacement time arrives. As shown in Fig. 7E, the consumable chip is detachably attached to the fluorescent lamp. Peel off the seal attached to the consumable chip and install a fluorescent lamp. The reader / writer communicates without contact with the IC tag, detects the mounting state, and reads and writes the mounting state information. The use start judgment of a fluorescent lamp is made based on the loaded state information. If a certain life time elapses from the start of use, the user is notified to replace the fluorescent lamp.

First, the outline | summary of the function of the low pressure mercury discharge lamp is demonstrated, referring FIG. The light emitting tube 2 is the same as a conventional discharge lamp. The base 5 has a plurality of lines of the lamp 1 to be mounted on the light source device. Terminal part provided in the bottom of the recessed part (upstream recessed part 11, downstream recessed part 12) of the opposite side (upstream base side 9, downstream base side 10) of the base 5 ( The convex terminal 30 and the concave terminal 31 are electrically connected to the communication line 40 with each other. A plurality of pairs of terminal portions (convex terminal 30a and concave terminal 31a, convex terminal 30b and convex terminal 31b) are connected to the opposite side so as to be connected to the terminal portions of adjacent bases 5. It is installed. The convex terminals 30a and 30b are connected to the first communication lines 40a and 40b to the corresponding concave terminals 31a and 31b in the inclined position. The IC chip 20 is connected to the second communication line 40c to the convex terminal 30c, which is the auxiliary terminal portion provided on the upstream side side surface 9. The IC chips 20 of the lamp 1 are individually connected to the terminal portions of the base 5 of the array stage when the bases 5 are connected to each other. When the read / write means is connected via the terminal portion 30 of the lamp 1 at the arrangement stage, the lamp information can be read and written individually to the IC chip 20. In the IC chip 20, necessary information is written from time to time after completion of lighting from the manufacturing stage.

The information written on the IC chip includes lamp information, transportation information, unpacking information, and lighting information. This information will be described below. The lamp information includes lamp individual information and device setting information. Individual lamp information includes the date of manufacture, manufacturer name, place of manufacture, production line, lamp type, breed number, lot number and identification number. The device setting information is the rated lamp current, rated lamp voltage, cooling conditions, the installation time limit, the usage limit time, and the like. The lighting information includes a lighting start date, a light off date, a flashing date, a lighting condition, a lighting arrangement, the number of flashes, an integrated lighting time, a device object number, a device setting, a device error information, and a prohibition information. Here, the lighting arrangement is information indicating where the lighting of the plurality of lamps is arranged. This information can be used not only for managing the use situation of the lamp, but also for investigating the cause in case of abnormality in the lamp.

Next, with reference to FIG. 2, the light source device which mounted and arranged the lamp of several line is demonstrated. The terminal block 51, the lamp 1A, the lamp 1B, and the lamp 1C are adjacent to each other on the side of the base 5. The concave terminal 31Sa of the terminal block 51 is electrically connected to the convex terminal 30Aa of the lamp 1A. The concave terminal 31Sb of the terminal block 51 is electrically connected to the convex terminal 30Ab of the lamp 1A. It is electrically connected with the concave terminal 31Sc of the terminal block 51 and the convex terminal 30Ac of the lamp 1A. The concave terminal 31Aa of the lamp 1A is electrically connected to the convex terminal 30Bb of the lamp 1B. The concave 31Ab of the lamp 1A is electrically connected to the convex terminal 31Bc of the lamp 1B. Nothing is connected to the convex terminal 30Ba of the lamp 1B. The concave terminal 31Bb of the lamp 1B is electrically connected to the convex terminal 30Cb of the lamp 1C. The concave terminal 31Ba of the lamp 1B is electrically connected to the convex terminal 30Cc of the lamp 1C. Nothing is connected to the convex terminal 30Ca, the recessed terminal 31Ca, and the recessed terminal 31Cb of the lamp IC.

By connecting the plurality of lamps 1 in this manner, the concave terminal 31Sa of the terminal block 51 is electrically connected to the IC chip 20C of the lamp 1C, and the concave terminal 31Sb of the terminal block 51. ) Is electrically connected to the IC chip 20B of the lamp 1B, and the concave terminal 31Sc of the terminal block 51 is electrically connected to the IC chip 20A of the lamp 1A. With this configuration, the read / write device of the light source device can read-write the information recorded in the memory of the IC chip 20 of each lamp 1. The terminal portion may have a structure in which only the lamp 1 can be removed from the light source device. 2B is a diagram illustrating an example in which a dummy base is inserted. By removing some of the discharge lamps and attaching the dummy base 15, the amount of light can be reduced. The dummy base 15 includes only the IC chip 20D, the terminal portion 30D, and the communication line 40D. The communication line 40D of the dummy base 15 and the base 5 on both sides are connected. Information indicating that the base is a dummy is recorded in the IC chip 20D.

Next, a read / write method of the IC chip will be described with reference to FIG. Lamp information and lighting information are recorded in the memory of the IC chip 20. Under the control of the system unit of the light source device, the read / write device receives lamp information for each IC chip 20A, 20B, 20C of the lamps 1A, 1B, IC through the terminal block 51 and the communication line 40. And reading of the lighting information is performed. The communication method between the IC chip 20 and the read / write device may be a USB connection or a SCSI connection used for a PC peripheral device or the like, or may be an application of the authentication technology of an IC card used for a cash card or the like. . It may be a simpler communication. The system unit of the light source device combines the information of the storage device with the information read out from the IC chip 20 to determine whether each lamp is lit. As a result, the light source device may display that the lamp cannot be turned on or turn on the lamp automatically.

A method of reading and writing an IC chip from the time the lamp is manufactured to after the use stops will be described. At the time of lamp manufacture, lamp information is written into an IC chip. When the lamp is attached to the light source device, before the light source device turns on the lamp, the lamp information written on the IC chip or the lighting information is read, and the lighting is judged as to whether the lamp is lit or not, and the display and operation shown below are performed. In the case where the IC chip is not recognized or in the case of lamp varieties that are not suitable for the light source device by the lamp information, the light source device issues a warning. Not only can the light source device warn the operator, but the lamp may be forcibly disabled. Of the plurality of lamps of the light source device, no power is supplied to the lamp at the position where the IC chip is not recognized. Do not supply power even for lamp varieties that are unsuitable for the light source device. The lamp of the position where it is judged that other lighting is possible is turned on. For example, when only three lamps are attached to a four-light source device, power is not supplied to the position of the fourth lamp.

During the period in which the lamp is being used, the following lighting information is written in the light source device. When the lamp is turned on, the lighting start date, lighting condition, and the like are written on the IC chip. Even after the prescribed time is turned on, the lighting time, lighting conditions, etc. are written to the IC chip. Furthermore, if the lighting time exceeds the life of the lamp, a warning is given to the operator or forced off. When the lamp is turned off, the lighting time and the lighting date are written to the IC chip. If the system unit of the light source device determines that the lamp is in an abnormal lighting state, the lamp is forcibly turned off, and then the abnormal state and the occurrence date and time record are written to the IC chip as lighting information. The abnormal state is recorded as an error code. In the case of a lamp failure in which re-lighting is impossible, the lighting information for which the use is prohibited is written into the IC chip. Even when the lamp is re-lit, before the light source device turns on the lamp, the lamp information and the lighting information written in the IC chip are read to determine whether the lamp is lit. Therefore, even when the lamp is replaced in the middle of its life, the usage history such as the lighting time remains as a record on the IC chip of the lamp main body, so that the lamp life can be managed for each lamp.

Lamps that have reached their specified life are written on the IC chip that they have been banned because they have reached their specified life. In addition, if a restart is not possible due to an abnormal lamp, lighting information indicating that use is prohibited is written to the IC chip in the lamp determined by the system of the light source device. A lamp having an IC chip in which usage information is set to be prohibited from use is rejected by the judgment of lighting of the light source device in the system of the light source device, and therefore can be prevented from being accidentally re-lit. Furthermore, in the light source device, the lamp information may be read from the IC chip and recorded in the storage device as the lamp which has been stopped. By retrieving the IC chip which has been stopped, the usage status of the lamp can be grasped from the lighting information of the IC chip, which can be useful for future lamp quality control. In addition, when the lamp stops lighting due to an abnormal lamp, it may be helpful to investigate the cause thereof.

By configuring as described above, lamp information can be managed. The occurrence of an accident due to the use of a lamp which is not suitable for the light source device can be prevented. Moreover, since the terminal part is provided in the bottom face of the recessed part of the lamp base side surface, it can use also in the conventional light source apparatus which does not manage lamp information. In addition, it is possible to flexibly cope with a change in the number of uses. Even when a plurality of lamps are arranged side by side, wiring of the communication line between the lamp and the light source device is simplified. Since the communication line is also connected just by attaching the lamp, the lamp replacement work is easy. In addition, since the communication line is renewed with lamp replacement, reliability does not deteriorate even when used for a long time in a high temperature region.

The communication line is electrically connected by fitting the convex terminal and the concave terminal. The terminal portion is not limited to this, and a known appropriate connector may be used. The communication lines of a plurality of lines may be bundled together to form one cable, and may be connected at a terminal portion which is one connector. The communication line may be a conductive foil or a film instead of a wire. Although three examples of communication lines were described with three discharge lamps, four or more discharge lamps can be managed by using four or more communication lines.

Next, an example using one communication line will be described. 4 is a diagram illustrating a state in which a discharge lamp is arranged in a line in a light source device. One communication line is used for serial communication, and one convex terminal and one concave terminal are provided in the discharge lamp. With this configuration, the communication line and the terminal portion of the base of the discharge lamp are simplified. As a serial communication method, a known communication method may be applied.

4B is a diagram illustrating an example in which a dummy base is inserted. In a light source device in which a plurality of lamps are lined up and lit, when sufficient light irradiation can be performed without turning on some lamps, the light source device may be used in a state in which some lamps are not turned on or in a detached state. have. Since the IC chip is connected to the reading device via the communication line of the lamp near the reading device, the IC chip and the reading / recording device are not connected unless the lamp is mounted on the side near the reading device. Therefore, as shown in FIG. 4, the dummy base 15 is attached to the mounting part of the lamp which is not lighted, and a lamp is arranged. The dummy base 15 is not provided with a light emitting tube or a feed line, but is composed of only a base having an IC chip 20D, terminal portions 30D, 31D, and a communication line 40D. The downstream lamp is also connected to the read / write device by the communication line provided in the dummy base. Information indicating that the base is a dummy is recorded in the IC chip 20D. Therefore, the system unit of the light source device can detect that the dummy base is mounted by the read / write device. Do not supply power or cooling medium to the place where the dummy base is mounted. Other operations are the same as in the above example.

As described above, in the first embodiment of the present invention, since the uneven terminal connecting the base adjacent to the base of the low-pressure mercury discharge lamp and the communication line connecting the uneven terminal are provided and the IC chip connected to the uneven terminal, the simple configuration The lamp information can be managed reliably by the IC chip.

Example 2

Embodiment 2 of this invention is an excimer lamp provided with the uneven | corrugated terminal which connects the base adjacent to a base, the communication line which connects the uneven | corrugated terminal, and the IC chip connected to the uneven | corrugated terminal.

Fig. 5 is a diagram showing a state in which lamps are mounted in a light source device in Embodiment 2 of the present invention. In Fig. 5, the lamps 1A, 1B and 1C are excimer lamps. There is a light emitting portion consisting of a cylindrical outer tube 108 and an inner tube 107 arranged on the same axis. An inner electrode (not shown) is provided on the inner surface 107 of the inner tube 107. An outer electrode (not shown) is provided on the outer surface of the outer tube 108. The base 105 is one end for protecting and holding the light emitting tube with the light source device. The tip side base 106 is another stage for protecting and holding the light emitting tube with the light source device. The feed line 4 is a line electrically connected to the inner electrode and the outer electrode for supplying electric power to the discharge lamp. Since other configurations are the same as those in the first embodiment, description thereof is omitted.

The lighting operation of the excimer lamp is as follows. Xenon gas is enclosed in the light emitting tube which consists of an inner side pipe | tube and an outer side pipe | tube. A dielectric barrier discharge is generated by applying a high frequency voltage of about 20 KHz between the inner electrode disposed on the inner surface of the inner tube and the outer electrode disposed on the outer surface of the outer tube. The xenon excimer light (wavelength 172 nm) generated at this time can be efficiently taken out through the outer electrode 36 of the metal mesh. In addition, the voltage to which xenon gas is sealed and applied by the same structure can also be made into the high frequency of several MHz. Also in this configuration, xenon excimer light (wavelength 172 nm) is emitted. In addition, when the inclusion is made of mercury and an argon gas for starting, low-frequency mercury can be discharged to obtain ultraviolet light characteristic of mercury having a wavelength of 254 nm or 185 nm. By configuring in this way, the same effect as in Example 1 can be obtained. The dummy base can be used similarly.

In the light source device 50, the lamp unit is protected by the unit protection holder 53. When the lamp unit is fitted to the unit protection holder, the communication line of each lamp unit is electrically connected to the terminal block 51 via the relay terminal 54. The IC chip of each lamp unit is electrically connected to the reading device through a communication line and a terminal block. The lamp unit 205C is in a state before being inserted into the unit protective holding part of the light source device. The lamp unit 205A is inserted into the unit protection holding part of the light source device and is kept protected.

The dummy unit 215 is a unit comprised only of a lamp housing, without providing a lamp or a feeder. In the light source device, by attaching the dummy unit to the portion of the unit that is not lit, the light source device can recognize that the communication line is connected and the dummy unit is mounted by the IC chip as in the first embodiment. In addition, in the light source device, the dummy unit also serves as a cover of the unit protective holding unit that is not used. By using the dummy unit as a cover of the unit protection holding part, light from the irradiation surface is prevented from entering the back side, and cooling air from the back side is prevented from entering the irradiation surface side. The lamp 1 is a short arc type ultra high pressure discharge lamp. The reflecting mirror 207 may be parallel light. The communication line may be of parallel type. Since the other structure is the same as that of Example 1, description is abbreviate | omitted. Although the example of the projection display device has been described, the present invention can be applied to other than the projection display device. In addition, the side surface of a protection holding means means not only the side surface of the base of a square pillar (box shape), but also the circumferential side surface of the circumferential base.
