之資訊之裝置。排出溝157設置於蓋部151，連接燈頭托座 140之外部與孔部54。 1C標籤130係具有1C晶片及天線部之ic標籤。讀寫器 15 160係進行1C標籤之放電個別資訊之讀寫之裝置。ic晶片具 有記憶裝置。於記憶裝置記錄放電燈泡之個別資訊。藉由 天線部，以讀寫器進行記憶裝置之資訊之讀寫。 參照第4圖及第5圖’說明如上述構成之本發明第2實施 例之光源裝置之功能及動作。首先，就以讀寫器讀寫1C標 20 籤之方法作說明。於突出部123之端部嵌入管帽223。於管 帽223保持1C標籤130。1C標籤130以讀寫器16〇讀寫有關於 放電燈泡之資訊或有關於輸送之資訊。1C標籤130為與讀寫 器160以電波進行通信’管帽223為以通電波之材質。由於 放電燈泡亮燈時，於燈頭120通電，故管帽22之絕緣性材質 16 200915380 使用特氟隆(註冊商標）等氟樹脂。藉使用絕緣性材質構成之 管帽223，可保持1C標籤130免於施加至燈頭120之高電堡。 特別是需保護免於亮燈時之強力起動脈衝。讀取放電燈泡 個別資訊之結果，若為正確之放電燈泡時，可將電力供給 5 至放電燈泡，使放電燈泡亮燈。 接著，就冷卻1C標籤及讀寫器之方法作說明。於蓋部 151設置4條排出溝157。燈頭120安裝於燈頭托座140，在燈 頭120之圓筒部端面22與燈頭托座140之蓋部151抵接之狀 態下，孔部154亦藉由排出溝157’於燈頭托座140之外部開 10 放。從供給管56供給至遮蔽空間55内之溫度調節介質S將配 設於遮蔽空間内之讀寫器160冷卻，通過突出部123與孔部 154之間隙’流出至燈頭120之圓筒部端面22與蓋部151間。 此時，由於溫度調節介質S之流動集中於突出部123與孔部 154之間隙’故可將管帽223集中冷卻。而可有效地防止管 15帽223之熱變形或熱造成之ic標籤130之惡化或破損。流出 至燈頭120之圓筒部端面22與蓋部151間之溫度調節介質S 一面將燈頭120之圓筒部21與蓋部151冷卻，一面從排出溝 157排出至燈頭托座140外。 如此’供給至遮蔽體150内部之溫度調節介質S第1，冷 20卻讀寫器160，第2 ’冷卻1C標籤130、管帽223及突出部123， 第3 ’冷卻蓋部151、燈頭120之圓筒部21，排出至燈頭托座 140之外部。是故，可有效率地進行燈頭托座14〇之冷卻。 由於將複數條溫度調節介質S之排出溝157設置成於燈頭 120之圓周方向均等，故可有效地冷卻燈頭12〇之圓筒部21 17 200915380 之端面。是故，可防止蓋部153及遮蔽體150之内部高溫。 再者，由於燈頭120之圓筒部端面22與蓋部151之接觸面積 狹小，故可減少從燈頭12〇之圓筒部端面22至遮蔽體15〇之 蓋部151之熱之傳達。此冷卻方法亦可適用於如第丨實施例 5之讀取光學顯示之情形，而可獲得相同之效果。再者，IC 標籤130與讀寫器160與第1實施例同樣地遮蔽電磁。由於可 以遮蔽體150保護免於電磁波雜訊，亦可遮蔽熱，故讀寫器 160可長期正確地讀寫IC標籤13〇。 如上述，在本發明之第2實施例，將光源裝置構造成於 10從複數溝排出溫度調節介質，強制冷卻而電磁遮蔽之燈頭 托座内部設置讀寫器，在將燈頭之突出部插入至燈頭托 座，保持燈頭之狀態下，讀寫位於突出部IC標籤之放電燈 泡個別資訊，故可保護IC標籤及讀寫器免於燈泡之熱、光 或高電壓’而可長期以高可靠度讀取放電燈泡個別資訊。 【第3實施例】 本發明之第3實施例係於燈頭與燈頭托座設置間隙，保 持燈頭，於從間隙排出溫度調節介質，強制冷卻而電磁遮 蔽之燈頭托座内部設置讀寫器，在將燈頭之突出部插入至 燈頭托座，保持燈頭之狀態下，讀寫位於突出部IC標籤之 20放電燈泡個別資訊之光源裝置。 第6 (A)圖係顯示光源裝置之讀寫器配置成相對之狀態 之縱截面圖。第6(B)圖係第6(A)圖之B-B截面圖。在第6圖 中’燈頭保持部241係藉與燈頭之圓筒部端面22抵接，保持 放電燈泡之構件。孔部254係設置於燈頭保持部之貫穿孔。 18 200915380 排出口 257係設置於遮蔽體之蓋部之貫穿孔。柱部242係相 對於遮蔽體250支撐燈頭保持部241之構件，在蓋部251上， 於燈頭之圓周方向均等地設置4個。固定於光源裝置之燈頭 托座240由内部配設有讀寫器160之遮蔽體250、在遮蔽體 5 250之蓋部上於燈頭220之圓周方向均等地設置4個之柱部 242、支撐於柱部242之燈頭保持部241構成。燈頭保持部241 具有孔部254。 參照第6圖，說明如上述構成之本發明第3實施例之光 源裝置之功能及動作。當將光源裝置安裝於放電燈泡時， 10將於端部設有保持有關於放電燈泡之個別資訊之1C標籤之 燈頭220的突出部123插入至燈頭保持部241之孔部254。使 燈頭220之圓筒部端面22與燈頭保持部241抵接，而將放電 燈泡保持於光源裝置。亦可將燈頭22〇以螺絲等固定於燈頭 保持部24卜放電燈泡由於以燈頭保持部241之孔部254以良 好位置再現性安裝，故管帽223與蓋部251之排出口 之間 隙亦可為大。 20 當抵接燈頭保持部241之孔部254之圓筒狀内面之部份 為管帽223時，由於f帽223為特_註冊商標)製，故使用 中有因熱變形之虞。是故’為使位置再現性良好，抵接燈

Individual information. [Second Embodiment] A second embodiment of the present invention is configured to discharge a temperature adjustment medium 15 from a plurality of grooves, and a reader/writer is provided inside the base of the lamp holder for forced cooling, and the projection of the base is inserted into the base. The holder, in the state of holding the lamp holder, reads and writes the light source device of the individual information of the discharge bulb located at the protrusion Ic. Figure 4(A) is a side view of a lamp head having a 1C label. Figure 4(B) shows a bottom view of a lamp head with a 1C label. Fig. 5(A) is a longitudinal sectional view showing a state in which the reader of the light source device is disposed in a relative state. Fig. 5(B) is a cross-sectional view taken along line A-A of Fig. 5(A). In the fourth and fifth figures, the same portions as those in the first embodiment are omitted. The protruding portion 123 is a small diameter portion of the base. The 1C tag 130 is a powerless 1C chip that holds individual information about the discharge bulb. The cap 223 is a bottomed cylindrical cap that holds the 1C wafer 10 130 at the front end of the projection 123. The reader/writer 160 reads the information about the discharge bulb held in the 1C tag and the information about the conveyance. The discharge groove 157 is provided in the lid portion 151, and is connected to the outside of the cap holder 140 and the hole portion 54. The 1C tag 130 is an ic tag having a 1C chip and an antenna portion. Reader 15 160 is a device that reads and writes individual information of 1C tags. The ic wafer has a memory device. Record the individual information of the discharge bulb on the memory device. By means of the antenna unit, the information of the memory device is read and written by the reader/writer. The function and operation of the light source device according to the second embodiment of the present invention configured as described above will be described with reference to Figs. 4 and 5'. First, the method of reading and writing the 1C standard 20 sign by the reader is explained. The cap 223 is fitted to the end of the protrusion 123. The cap 223 holds the 1C tag 130. The 1C tag 130 reads and writes information about the discharge bulb or information about the transfer with the reader/writer 16〇. The 1C tag 130 communicates with the reader/writer 160 by radio waves. The cap 223 is made of a conductive wave. Since the lamp cap 120 is energized when the discharge lamp is turned on, the insulating material of the cap 22 is used as a fluororesin such as Teflon (registered trademark). By using the cap 223 made of an insulating material, the 1C tag 130 can be kept from being applied to the high-voltage bunker of the cap 120. In particular, it is necessary to protect against strong starting pulses when lighting is off. Reading the discharge bulb The result of the individual information, if it is the correct discharge bulb, can supply 5 to the discharge bulb to make the discharge bulb light. Next, a method of cooling the 1C tag and the reader/writer will be described. Four discharge grooves 157 are provided in the lid portion 151. The base 120 is mounted on the base 140, and the hole 154 is also disposed outside the base 140 by the discharge groove 157' in a state where the cylindrical end surface 22 of the base 120 abuts against the cover 151 of the base 140. Open 10 to release. The temperature-regulating medium S supplied from the supply pipe 56 into the shielding space 55 cools the reader/writer 160 disposed in the shielding space, and flows out to the cylindrical end surface 22 of the base 120 through the gap between the protruding portion 123 and the hole portion 154. It is between the cover portion 151. At this time, since the flow of the temperature-regulating medium S is concentrated on the gap between the protruding portion 123 and the hole portion 154, the cap 223 can be collectively cooled. Further, deterioration or breakage of the ic tag 130 caused by thermal deformation or heat of the tube 15 cap 223 can be effectively prevented. The temperature regulating medium S flowing out between the end surface 22 of the cylindrical portion of the base 120 and the lid portion 151 cools the cylindrical portion 21 of the base 120 and the lid portion 151, and is discharged from the discharge groove 157 to the outside of the base holder 140. Thus, the temperature adjustment medium S supplied to the inside of the shielding body 150 is first, the cold 20 is the reader/writer 160, the second 'cooling 1C label 130, the cap 223 and the protruding portion 123, and the third 'cooling cover portion 151 and the base 120 The cylindrical portion 21 is discharged to the outside of the base holder 140. Therefore, the cooling of the lamp holder 14 is efficiently performed. Since the discharge grooves 157 of the plurality of temperature regulating media S are disposed to be equal in the circumferential direction of the base 120, the end faces of the cylindrical portions 21 17 200915380 of the base 12 can be effectively cooled. Therefore, it is possible to prevent the inside of the lid portion 153 and the shielding body 150 from being heated. Further, since the contact area between the cylindrical end surface 22 of the base 120 and the lid portion 151 is narrow, the heat transfer from the cylindrical end surface 22 of the base 12 to the cover portion 151 of the shield 15 can be reduced. This cooling method can also be applied to the case of reading optical display as in the fifth embodiment, and the same effect can be obtained. Further, the IC tag 130 and the reader/writer 160 shield electromagnetic waves in the same manner as in the first embodiment. Since the shielding body 150 can be protected from electromagnetic wave noise and the heat can be shielded, the reader/writer 160 can read and write the IC tag 13〇 correctly for a long period of time. As described above, in the second embodiment of the present invention, the light source device is configured such that the temperature adjustment medium is discharged from the plurality of grooves, and the reader/writer is provided inside the holder of the electromagnetic shield by forced cooling, and the protruding portion of the base is inserted into the light source. The lamp holder is held in the state of holding the lamp head, and the individual information of the discharge bulb located on the IC tag of the protrusion is read and written, so that the IC tag and the reader can be protected from the heat, light or high voltage of the lamp, and the reliability can be long-term with high reliability. Read the individual information of the discharge bulb. [Third Embodiment] A third embodiment of the present invention is characterized in that a gap is provided between a lamp cap and a cap holder, and the lamp cap is held, and a temperature-adjusting medium is discharged from the gap, and a reader/writer is disposed inside the cap holder for forced cooling and electromagnetic shielding. The protruding portion of the lamp cap is inserted into the lamp holder, and the light source device for reading the individual information of the discharge bulb of the IC tag of the protruding portion is read and written while the lamp holder is held. Fig. 6(A) is a longitudinal sectional view showing the state in which the reader/writer of the light source device is disposed in a relative state. Fig. 6(B) is a cross-sectional view taken along line B-B of Fig. 6(A). In Fig. 6, the cap holding portion 241 is held by the cylindrical end surface 22 of the cap to hold the member of the discharge bulb. The hole portion 254 is provided in the through hole of the cap holding portion. 18 200915380 Discharge port 257 is a through hole provided in the cover of the shielding body. The column portion 242 is a member that supports the cap holding portion 241 with respect to the shielding body 250, and four of the cap portions 251 are equally provided in the circumferential direction of the cap. The cap holder 240 fixed to the light source device is provided with a shielding body 250 in which the reader/writer 160 is disposed, and four column portions 242 are equally disposed on the cover portion of the shielding body 5 250 in the circumferential direction of the lamp cap 220, and are supported by The base holding portion 241 of the column portion 242 is configured. The cap holding portion 241 has a hole portion 254. The function and operation of the light source device according to the third embodiment of the present invention configured as described above will be described with reference to Fig. 6. When the light source device is mounted to the discharge bulb, the projection portion 123 of the base 220 having the 1C label holding the individual information about the discharge bulb at the end is inserted into the hole portion 254 of the cap holding portion 241. The cylindrical end surface 22 of the base 220 is brought into contact with the base holding portion 241 to hold the discharge bulb to the light source device. The cap 22 can be fixed to the cap holding portion 24 by screws or the like. Since the discharge bulb is reproducibly mounted at a good position by the hole portion 254 of the cap holding portion 241, the gap between the cap 223 and the discharge port of the cap portion 251 can also be Big. When the portion of the cylindrical inner surface of the hole portion 254 of the cap holding portion 241 is the cap 223, since the f cap 223 is made of a special trademark, it is thermally deformed during use. Therefore, in order to make the position reproducibility good, the portion of the cylindrical inner surface of the hole portion 254 that abuts against the cap holding portion 241 is made of a hard metal which is integral with the cylindrical portion.

On the other hand, when the portion of the cover portion 251 of the shield body 250 is close to the 255 A, the portion of the inner surface of the 257® is a metal large portion 123, there is a station at the top of the μ μ 1 _ 卩 251 The inner surface of the cylindrical inner surface of the discharge port 257 and the protruding portion 123 of the base 220 generate a lightning strike. Therefore, the portion of the cylindrical inner surface of the cover portion 2 51 close to the shielding body 250 19 200915380 is an electrically insulating cap 223. In this manner, even if the cover portion 251 of the shield 250 does not use the insulating member ', the base 220 and the shield 250 can be insulated. In the structure in which the base 220 is insulated by the shield 250, the structure of the shield 25 is complicated. Not only that, but also the thermal deformation is weak, and the strength of the weight supporting the discharge bulb is also weak. Since the insulator 250 is not insulated by the shield 250, the base retaining portion 241 and the shield 250 can be stabilized. By the metal forming the shielding body 250, the electromagnetic waves radiated from the discharge bulb can be surely shielded. Further, the holding portion 241 and the shielding body 10 250 are connected only to the column portion 242 having good thermal insulation property, and the heat transmitted from the base 22 to the shielding body 25 can be reduced. The temperature-regulating medium s supplied from the supply pipe 56 into the shielding space cools the reader/writer 160 provided in the shielding space 55, and flows out to the base holding portion 241 through the gap between the cap 223 and the discharge port 257 of the cover portion 251. Between the lids 251. At this time, since the flow of the temperature regulating medium S is concentrated in the gap between the cap 223 and the outlet 257 of the discharge 15, the cap 223 can be collectively cooled. Further, it is possible to effectively prevent deterioration or breakage of the IC tag 13 caused by thermal deformation or heat of the cap 223. The temperature adjusting medium s flowing out from between the cap holding portion 241 and the lid portion 251 cools the lid portion 251 of the mask body 250 and the cap holding portion 241, and is discharged to the outside of the cap holder 240 by the gap with the column portion 242. In this manner, the temperature-regulating medium s supplied to the inside of the shielding body 250 is cooled, and the 1C label 130, the cap 223, and the protruding portion 123 are cooled, and the third surface of the cooling cover portion 251 and the cap holding portion are cooled. Below the 241, the fourth cooling fin 242 is discharged to the outside of the base holder 240. Therefore, the cap holder 240 can be efficiently cooled. This cooling method is suitable for reading the optical display 20 200915380 shape can also achieve the same effect. The method of shielding the 1C tag 130 and the reader/writer 160 from the light of the bulb is the same as that of the second embodiment and the second embodiment. As described above, in the third embodiment of the present invention, since the light source device is formed in a gap between the base and the base, and the medium is inserted at the discharge temperature 5, the medium is forced to be cooled and electromagnetically shielded. The 1C tag reads and writes the individual information of the discharge bulb, so it can protect the IC tag and the reader from the heat, light or high voltage of the lamp, and can read the individual information of the discharge bulb with good reliability for a long time. [Fourth Embodiment] In the fourth embodiment of the present invention, a display reading portion is provided inside a holder for shielding electromagnetic and forced cooling, and a projection portion and a positioning convex portion of the base are inserted into the holder of the lamp holder to maintain the lamp holder. Next, the light source device of the discharge bulb individual information located at the display portion of the front end of the positioning convex portion of the lamp cap is read and written. Fig. 7(A) is a side view showing the base of the projection having the display portion. Fig. 7(B) 15 is a bottom view of the base of the projection having the display portion. As shown in the side view (A) and the bottom view (B) of Fig. 7, the positioning convex portion 324 is formed on the cylindrical end surface 22 of the base 320. Fig. 8(A) is a longitudinal cross-sectional view showing a state in which the display reading portion of the light source device is disposed to face the display portion. Fig. 8(B) is a C-C cross-sectional view of Fig. 8(A). As shown in Fig. 8, in the cover portion 351 of the shield body 350, in addition to the hole portion 354 of the projection portion 323 of the cap 320, a positioning hole 358 for inserting the positioning projection portion 324 is provided. When the cylindrical end surface 22 of the base 320 abuts against the lid portion 351 of the cap holder 340, the positioning hole portion 354 is not blocked, but is opened outside the shield 350 by the discharge port portion 357. In this configuration, the discharge bulb can be positioned when it is mounted on the light source device. 21 200915380 The function and operation of the light source device according to the fourth embodiment of the present invention configured as described above will be described with reference to Figs. 7 and 8. First, explain how to read the lamp information. Basically, as in the first embodiment, the display portion 33 is located at a point different from the front end surface of the positioning convex portion 324. The protruding portion of the base (10) is placed in the hole portion 354 of the base 340 of the base. To position the bulb, the positioning projection is inserted into the positioning hole portion 358. When the base 320 is fixed to the base holder 34, the display portion 33 is brought to a position opposed to the display reading portion 60. In this state, the display unit 60 reads the display of the display unit 330 to acquire the bulb information. Next, a masking method and a cooling method will be described. A member which is electrically insulated from the positioning convex portion 324 is provided in the covering body 350 made of metal. When it is a shield 350 made of an insulating body, it is covered with an electric shielding material. The other basic parts of the masking method are the same as in the first embodiment. The temperature adjustment medium 8 is caused to flow into the internal space of the shield 350, and the display portion 33A and the display reading portion 6A are cooled. The temperature-regulating medium s supplied from the supply pipe 56 to the shielding space 55 is cooled and disposed in the display reading portion 6A disposed in the shielding space, and flows out through the positioning protrusion 358 and the positioning hole 358 of the cover portion 351. It is between the end surface 22 of the cylindrical portion of the base 32G and the lid portion 351. At this time, since the flow of the temperature-adjusting medium 8 is concentrated on the gap between the positioning convex portion μ# and the positioning hole portion 358 of the lid portion 351, the display portion 33 can be collectively cooled. Therefore, it is possible to effectively prevent the deterioration of the display portion 33 due to heat or the color change. The temperature-adjusting medium s flowing out between the end surface 22 of the cylindrical portion of the base 320 and the lid portion 351 is discharged to the outside of the base holder 34. Therefore, the display portion 330 and the display reading portion 6 can be efficiently cooled. This cooling method is suitable for the case where the 耽 mark and the reader are used, and the same effect can be obtained. As described in the fourth aspect of the present invention, the light source device is configured to be provided with a display reading portion inside the holder that is shielded from electromagnetic shielding by 22 200915380, and the protruding portion and the positioning convex portion of the lamp cap are inserted into the holder of the lamp holder. In the state of holding the lamp cap, the individual information of the discharge bulb located at the display portion at the front end of the positioning convex portion of the lamp cap is read, so that the display portion and the display reading portion can be protected from the heat of the bulb, 5 light or high voltage, and can be long-term. Read the individual information of the discharge bulb with high reliability. Industrial Applicability The light source device of the present invention is most suitable as a light source device for protecting an individual information reading unit that reads individual information of a discharge lamp.
