Further, the configuration of such a projection type image display device has also been applied to a projection mode in which a projection television is represented in the future. The projection type image display device requires a high-intensity light source, and a light source device using a lamp (discharge type light-emitting tube) such as a halogen lamp and a mercury lamp for charging is built in. The light source device is provided with a reflector having a shape in which the light-emitting tube is covered in one direction in order to reflect the light emitted from the lamp of the light source in a desired direction. The reflector functions as a concave mirror by making the inner circular surface mirror-like, and Φ reflects the light emitted from the arc tube outward from the opening side of the reflector. Lamps such as metal halide lamps and high-pressure mercury lamps have a large heat release rate and reach a high temperature in use. If the lamp itself reaches a high temperature, the temperature of the inner surface of the lamp itself and the inner surface of the reflector (concave mirror) will rise excessively, which will cause various failures such as shortening of the lamp itself and deterioration of the reflective layer of the concave mirror. Therefore, in the projection type image display device, it is necessary to provide a cooling mechanism by cooling the fan around the light source device to blow air to the entire light source device to forcibly cool. In addition, the inside of the glass rods 106371.doc 1277709 and the support (glass support) contained in the 'light source luminaire (high-pressure mercury lamp) are sealed with harmful mercury and halogen gas, etc. More than 15 〇 atmospheric pressure, therefore, if the glass support is broken for some reason, not only will there be a loud sound of cracking, but also harmful materials and glass and other scattering. For this reason, in a light source device using a lamp having an input power of about 15 watts (W) or less, there is a simple sealed explosion-proof type in which the opening side of the reflector is closed by a glass plate or an optical lens to prevent cracking noise and harmful substances from leaking. Specifications. However, if the explosion-proof specification is used, the inner circular surface of the lamp and the reflector cannot be directly cooled by the outer φ portion. Therefore, the light source device with an input power exceeding about 150 W is generally not subjected to the explosion-proof specification. Further, in the light source device in which a glass plate or an optical lens is provided on the opening side of the reflector in Patent Document 1, in order to allow air to be blown to the inner surface of the lamp and the reflector, an opening is provided in a part of the reflector, through which the opening is provided. To send cooling air into the inside of the reflector. Further, in the xenon lamp of the type different from the lamp of the light source device described in Patent Document 2, one of the electrodes supporting the opposing faces is structurally coupled to the reflector. Further, in the light source device disclosed in Patent Document 3, in order to reduce the temperature of the light-emitting sphere portion (light chamber portion) of the light-emitting tube, a heat-conducting contact body projecting from the edge of the light-emitting tube mounting hole of the reflector is provided. . [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2005-71814. There is an opening, because 106371.doc 1277709 - & If the light source of the lamp is broken, there will be a problem that it is impossible to prevent the explosion sound and harmful substances from passing through the opening and not leaking to the outside. In addition, in the light source device of the explosion-proof gauge, there is a problem that the inside of the reflector and the inside of the reflector cannot be sufficiently cooled. On the other hand, the lamp which is a light source is configured such that the electrodes are opposed to each other in the inner cavity of the lamp chamber portion formed at the central portion of the glass support body sealed at both ends, and the lamp chamber portion has a heat resistance of about 100 (TC). The package of the end only has a heat resistance of about 400 ° C. The lamp of the above-mentioned structure is mounted on the reflector at one end, and the heat generated by the lamp on the glass support is illuminated by the lamp chamber to the opposite reflection. The heat dissipation in the range of the end portion of the mounting side of the device is transferred to the reflector by heat conduction, and therefore, there is a certain degree of relaxation. • However, the package from the lamp chamber portion to the end portion on the opposite side of the mounting side The range of the portion protrudes in the reflector in a state of being suspended in the air, so that the generated heat cannot be efficiently moved and accumulates, resulting in a problem that the temperature is higher than that of the mounting side. The temperature of the light-emitting tube rises. • It is inclined to use both the explosion-proof light source device and the non-explosion-proof light source device. In addition, today's projection type image display devices have appeared more than the mouth-and-mouth type. In the small-sized projection type image display device, the mounting degree in the device casing is increased, and it is more difficult to ensure good cooling performance for the light source device. Further, the configuration of Patent Document 2 There is only a light source device in which a lamp holder that supports only one side electrode and a lamp (light-emitting tube) that has an encapsulation portion at both ends and a lamp in the center portion of the lamp chamber are disposed on the reflector, and the structure is completely different. The configuration of the patent document 2 106371.doc 1277709 according to the electrode of the surrounding support is not only structurally unsuitable for the light source device in which the lamp is mounted on the reflector, but also cannot directly move the heat for the lamp to Further, in the light source device of Patent Document 3, the heat conduction contact body provided by the hole edge of the arc tube mounting hole of the reflector is in contact with the lamp chamber portion to the reflector. The part on the mounting side, therefore, the heat generated in the range from the lamp chamber portion to the protruding side cannot be directly moved to the reflector. The present invention is directed to the above problems. The invention provides a light source φ device and a projection type image display device, which can effectively suppress the heat generated by the lighting of the light-emitting tube regardless of whether it is an explosion-proof specification, in particular, the light of the light-emitting tube to the side of the dog to the side of the dog In order to solve the above problems, the light source device of the present invention has one end of the light-emitting tube such that the light-emitting tube protrudes toward the reflection side from the center of the reflector having the concave inner circular surface as the reflection surface. Mounted in the reflector, and the light-emitting tube is disposed opposite to the electrode chamber portion formed between the package portions on the both end sides, and is formed to include a protruding portion of the lamp chamber portion of the light-emitting tube. In the present invention, since the light-emitting tube and the reflector are connected by the heat-conducting member, the heat generated by the light can be directly transmitted to the reflection via the heat-conducting member. Device. As a result, the temperature rise of the arc tube is suppressed. When the entire light source device is turned on, good temperature characteristics are ensured, thereby prolonging the service life of the arc tube and the reflector. Further, as a material for the heat conduction member, a metal such as copper or aluminum having a good thermal conductivity and a ceramic enamel formed by nitriding are used.

When the heat conducting member is heated, the member included in the heat conducting member may thermally expand, and the arc tube disposed at the center of the reflector may be subjected to stress and displaced, and in the worst case, the glass support of the arc tube may be broken. However, in the present invention, by the absorption and offset of the amount of thermal expansion by the curved portion, the light pipe is not subjected to stress, and the above abnormality can be prevented. Further, the bending direction of the curved portion can be appropriately set depending on the size, specifications, and the like of the light source device.

According to the invention, the curved portion at which the inner circular surface of the reflector abuts is provided on the projecting end of the projecting portion, so that it is easy to perform the swing on the reflector side of the heat conducting member. That is, only the heat conducting member is mounted by the reflecting side opening of the reflector, and the back curved portion abuts against the inner circular surface of the reflector to fix the heat conducting member. Further, since the bent portion abuts against the inner circular surface of the reflector, heat can be conducted from the projecting portion to the reflector via the bent portion.

Further, the projecting end fitted into the slit is fitted to the periphery of the groove, so that heat can be conducted from the heat conducting member to the reflector via the fixed position. Furthermore, even if the heat conduction of the protruding portion is irradiated by the reflected light of the conduction and the reflector, the thermal expansion of the protruding portion through the groove does not hinder the expansion of the protruding end, and therefore, even if the thermal expansion expands toward the protruding end side, The arc tube can be prevented from being unnecessarily stressed. In the light source device of the present invention, the projecting end of the projecting portion is provided with a bent portion, and the bent portion abuts against the outer circular surface of the reflector. According to the invention, the curved portion abutting on the outer circular surface of the reflector is disposed at the protruding end of the protruding portion, so that the heat conducting member can be externally embedded in the reflector by the bent portion passing through the protruding end of the groove. The outer circular surface, therefore, not only becomes true to the reflector, but also expands the contact area with the reflector, thereby improving the heat transfer efficiency to the reflector. Further, when it is desired to strengthen the fixing of the bending portion to the reflector, an adhesive (fixing agent) having good thermal conductivity, screwing, or the like may be used, and such work may be performed on the outer circular side of the reflector.

In the case of the cross-sectional area, & 106371.doc -14- 1277709 卩 increases the size of the first direction to ensure not only good 埶 conductivity, but also to minimize the degree of reflected light from the shielding reflector; The light source device of the present invention is characterized in that the cross-sectional shape of the projecting portion perpendicular to the extending direction is a wedge shape, and the tip end side of the light-emitting tube is wedge-shaped. According to the invention, the cross-sectional shape of the projecting portion is a shape corresponding to the mounting side of the light-emitting tube as the tip end side, and therefore, the degree to which the reflector light is shielded can be further suppressed. That is, each of the rays forming the light (beam) reflected by the reflector has a certain curvature due to the reflecting surface of the reflector, and travels in a certain degree - surface diffusion - plane. Therefore, by making the cross section of the protruding portion into a wedge shape of the tip of the light-emitting tube mounting direction, the position of the shielding light is only - the front end position of the wedge shape, if the light travels along the oblique side of the wedge shape, the wedge shape is The light at the end position is also not obscured by the extension, so that the reduction in the amount of light is minimized. The light source device of the present invention is characterized in that the surface of the heat conduction member is covered with an oxidation preventing film.

The above glossy surface is suitable. Further, the oxidation preventing film is preferably a component containing cerium oxide, a quartz plating film or the like. The light source device of the present invention is characterized in that the reflector is coated with a thermal diffusion film on the reflecting surface. According to the invention, since the reflecting surface of the reflector is covered with the thermal diffusion film, the temperature of the reflecting surface does not rise excessively, and not only the deterioration of the reflecting surface but also the good heat dissipation of the reflector itself can be maintained. The light source device of the present invention is characterized in that the substrate of the reflector is exposed at a position where the heat conducting member of the reflecting surface is coupled. According to the invention, on the reflecting surface of the reflector, the substrate of the reflector is exposed at the position where the heat conducting member is joined, and therefore, the heat diffusion member is not conducted in the path of the heat conducting member to the reflector. As a result, there is no possibility that the thermal diffusion film is hindered by heat conduction, and heat can be efficiently conducted. The light source device of the present invention is characterized in that the reflector has a diffused heat sheet on the outer circumferential surface. According to the invention, the reflector has fins on the outer circumferential surface, so that the heat dissipation of the reflector can be further enhanced, the temperature rise of the reflector can be suppressed, and heat conduction from the heat conducting member to the reflector can be smoothly performed.

依本發明，具有使熱傳導構件嵌合於反射器之圓周面之 I06371.doc -19- 1277709 . 嵌合環狀部，因此，可確保與發光管之接觸面積大，而使 熱傳導構件具有的熱平順地傳導至反射器。 依本發明，乃將抵接於反射器内圓面上之彎曲部設於伸 出部之伸出端上，因此，不僅使熱傳導構件易於安裝於反 射器上，並以彎曲部確保對反射器之傳熱位置，可得到有 效率的熱傳導。 依本發明，乃將抵接於反射側開口之端面上之彎曲部設 φ 於伸出部之伸出端上，因此，不僅經由彎曲部確保對反射 器之傳熱位置’並在欲將熱傳導構件接合固定於反射器上 的情況中，能以反射器之端面位置之彎曲部，簡易地進行 為了接合之作業。 - 依本發明，僅需將伸出端嵌入槽内，便可簡易地將熱傳 導構件安裝於反射器側，並可將嵌入於槽内之伸出端抵接 於槽之周緣而平順地進行對反射器之熱傳導。 依本發明，乃將抵接於反射器外圓面之彎曲部設在伸出 • 部之伸出端上，因此，彎曲部可外嵌於反射器之外圓面而 使熱傳導構件穩固地安裝於反射器上，並亦可經由彎曲部 進行對反射器之熱傳導，因而可提高熱傳導效率。 依本發明，伸出部之剖面在與發光管之長邊方向平行之 第一方向上之尺寸比相對於第一方向為垂直之第二方向上 之尺寸還大，因此，不僅可確保良好之熱傳導性，並可將 反射器之反射光之遮蔽程度抑制至最小程度。 依本發明伸出部之剖面形狀為以相當於發光管安裝方向 之側為頭尖之楔形，因此，可進一步抑制反射器之反射光 106371.doc 20· 1277709 之遮蔽程度。 依本發明，藉由在熱傳導構件之表面上以氧化防止膜被 覆，可抑制熱傳導構件因反射器之反射光而受熱，即使在 光源裝置之亮燈中，仍可維持熱傳導構件之良好的熱傳導 性。 ”、 依本發明，乃以熱擴散膜被覆反射器之反射面，因此，

外線’目視上為白色光線。此外，在射出光線的焦點附近 所配置之色轉輪2至少分割成可使紅色、綠色、及藍色光線 106371.doc •22- 1277709 度切換’因此，錯覺上會目視成彩色圖像。 圖2所示的為上述投影型圖像顯示裝置1所適用之光源裝 置10之分解狀態。本實施方式之光源裝置1〇為防爆規格， 具有將内部配置有發光管12之反射器u之開口 Ud加以封 閉的碟形之防爆玻璃29 (相當於透光性構件）。此外，亦適 用光學透鏡來取代防爆玻璃29。此外，光學裝置1〇具有將 I光管12及反射器11連結起來的扇葉形之熱傳導構件2〇， _ 使因亮燈而發光管12所產生的熱藉由熱傳導構件2〇傳導至 反射器11。以下詳述光源裝置10之各部構造。 反射器11係如圖3所示般地，在内圓面Uf形成橢圓面或 雙曲面的凹面鏡11a之成為反射側之開口 Ud侧的周緣上設 - 凸緣部1 lb，此外，在相反侧之端部上，則有為了安裝發光 管12之管部lie由頂部突出。凹面鏡部lla、凸緣部llb、及 管部lie相當於反射器11之基材，基材所用的為熱傳導率為 10 W/m · K以上之金屬材料，本實施方式中使用的為熱傳 • 導率約200 W/m · K的鋁。 凹面鏡部11a之凹形内圓面llf為反射面，為了得到高反 射率’有將銘或銀等之金屬蒸鍍於内圓面11 f上。此外，除 金屬蒸鍍以外，亦可以交互蒸鍍Si02等之低折射率材料及 Ti〇2等之咼折射率材料而成之介電體多層膜成膜出内圓面 11 f或鏡面研磨内圓面11 f本身。 凹面鏡部11a形成有發光管12安裝用之穴部iih，而使内 圓面Ilf之中心頂部lli及管部lie之内部連通。此外，内圓 面1 If之凸緣部1 lb側之周緣上，凹設有為了嵌合熱傳導構 106371.doc -24- 1277709 ， 成為光束密度高之區域R，區域R以外之位置則成為比區域 R光束密度低之區域。此外，内圓面Ilf中，乃以相對於形 成光束之光及内圓面11 f之交點上之切線，射入角及反射角 為相等之方式進行反射。 發光管12之於反射器11上之具體安裝，乃將形成發光管 12之玻璃支撑體13之一端13a***反射器11之穴部lih，以 發光管12之軸芯對準在反射器u之中心頂部1丨丨上通過之 φ 中心軸C，並使燈室部13c之中心附近之發光點與反射器上工 之焦點一致之方式配置，以此狀態藉由固著劑丨8來固接兩 者。藉由以上述般之方式固接，發光管12被在反射器丨丨之 * 内部突出之狀態支撐。 “ 另一方面，連結發光管12及反射器11之熱傳導構件20 (參 照圖2)為銅製，不僅設有由設於中央之圓柱形之外嵌環狀 部21呈放射狀伸出之3條伸出部23至25，並使各伸出部以 至25之伸出端連結於環狀之嵌合環狀部22，研磨各部2 i至 • 25之表面而確保光澤性後，以氧化防止膜被覆。本實施方 式中，氧化防止膜所用的為科萊恩（clariant)公司製之稱為 NL110之產品，惟亦將石英塗佈製者、及以二氧化矽為成分 者應用作為氧化防止膜。 如圖3及5所示、中央之外嵌環狀部21乃使内部之空間部 2 la具有能夠外嵌於發光管12之突出之端部nb侧之封裝部 13d (由燈室部13c至端部13b之部分：參照圖4(a))之大小， 長度則為比封裝部l3d稍短之尺寸。由上述般之外嵌環狀部 21之長邊方向上之一端側之圓周面，使各伸出部以至乃伸 106371.doc -26- 1277709 如上述般地安裝熱傳導構件20後，將發光管12之突出側 之引腳線d2由孔部1 lj向反射器11之外侧拉出，接著，將防 爆玻璃29接合於反射器11之凸緣部lib之凹槽部lie，完成 防爆規格之光源裝置10。 如對完成之光源裝置10之引腳線dl、d2進行所需之連 接，投入電力的話，發光管12會發光，光源裝置1〇會亮燈。 亮燈中，發光管12之各鎢電極14、15會放電而產生光及熱， 產生的光會如圖3所示般地經反射器11反射通過防爆玻璃 29而向外射出。此時，會遮蔽到光束密度高之區域r的僅有 由發光管12側向反射器11側以放射狀伸出之各伸出部23至 25，因此，即使安裝熱傳導構件2〇，幾乎不會有使光源裝 置10之照射特性惡化的情形。 此外，由光源裝置1〇照射出來之光中，因熱傳導構件2〇 之存在，藉伸出部23至25會有一部分之光被遮蔽，因此， 在部分會產生陰影。然而，在投影型圖像顯示裝置丨中，如 圖1所示，由光源裝置10所照射來之光會射入圓柱形透鏡 3’、因此，藉由以圓柱形透鏡3之全反射，通過圓柱形透鏡3 光的‘、、、度έ均勻化。依此結果，熱傳導構件之伸出部 23&25^彡+不會被投影’影子不會顯示在被投影之圖像 此外’因發光管12所產生之熱，玻璃支樓體⑽溫度會 為本實施方式之光源裝置10中之散熱方式，有對 ^ ”、、寻^的二種方式，該三種方式當中 ”、、移動效率最高的為熱傳 华一為幅射。以下說明各方 106371.doc -28- 1277709 式中之熱移動。 對流熱傳達乃以兩個系統進行熱移動，該兩系統包含： 一為經由存在於發光管12周圍之封閉在反射器11内之空 氣’使熱由發光管12傳達至反射器11者；及一為經由存在 於發光管12周圍之空氣，使熱由發光管12傳達至防爆玻璃 29者。此外，幅射則在發光管12及反射器1]L之間進行。 隶後’熱傳導存在有兩個糸統之熱路徑，第一個熱路徑 φ 係熱由發光管12之成為反射器11安裝側之一端部13a，經由 固著劑18，傳導至反射器丨丨者。此外，關於上述之對流熱 傳達、幅射及第一個熱路徑之熱傳導，亦見於以往之防爆 規格之光源裝置。 ’ 熱傳導之第二個熱路徑係本發明之光源裝置1 〇之特徵 者，其係使熱由發光管12之比燈室部13c更靠突出側之封裝 部13d，經由熱傳導構件20,而傳導至反射器丨丨者。發光管 12在燈室部13c的溫度最高，因該燈室部13c之熱會傳至突 • 出側之封裝部13d，封裝部13d之溫度會上升，惟在本發〇 之光源裝置10中，乃將封裝部i3d之熱經由所謂熱傳導構件 20之熱路徑而移往反射器U，抑制封裝部Ud之溫度上升， 從而謀求發光管12之長壽命化。 尤其，本實施方式中，熱傳導構件2〇之中央側之外嵌環 狀部21乃由燈室部13c之附近位置外嵌封裝部ud，因 封裝和d及外«狀部韻了充分的接觸面積，使由成 為高溫之燈室部⑸移至封裝部13d之熱有效率地移至外山 環狀部21 (熱傳導構件20)。此外，移至外嵌環狀部Μ: 106371.doc -29- 1277709 會經由三方向之伸出部23至25向伸出方向移動而移往外侧 之嵌合環狀部22。經由伸出部23至25而移往外側之嵌合環 狀部22之熱會接著經由與嵌合環狀部22接觸之嵌合面iig 而移往反射器11。 此外，如上述般之經由熱傳導構件20之由發光管12之封 裝部13d至反射器11之熱移動，會在封裝部13d比熱傳導構 件20及反射器11高溫時開始，並進行至封裝部13(1之溫度比 熱傳導構件20及反射器11還低為止。此外，發光管12之封 裝部13d上所外嵌之外嵌環狀部21之長邊方向之尺寸以愈 接近燈室部13c之方式設定，愈能提高對燈室部13c之散熱 性，相反地，愈以遠離燈室部13c之方式設定，愈能以封裝 部13d為對象提高散熱性。 反射器11其本身具有散熱特性，因而上述由發光管12移 來之熱最終會以反射器11散熱。因此，發光管12會被熱傳 導構件20冷卻，亮燈中成為高溫之燈室部13c的溫度被抑制 在800°C至1000°C以下，突出侧之封裝部13d之溫度確實地 被抑制在400°C以下。因此，對發光管12可投入超過以往防 爆規袼上限150 W的200 W以上之電力，在本實施方式之光 源裝置10除了以往之使熱散去之路徑之外，尚存在藉由熱 傳導構件20之路徑，因此，亮燈中亦能將發光管丨2維持在 上述溫度，並藉由投入200 W以上之電力而比以往更能確保 高亮度特性。 另一方面，光源裝置1〇之亮燈中，熱傳導構件20 (尤其伸 出部23至25)會被照射反射器11所反射之光束，惟熱傳導構 106371.doc -30- 1277709 件20之表面藉由研磨已經確保有光澤性，因此，使照射之 光束被以表面反射而使熱傳導構件20 (伸出部23至25)吸熱 率減低。此外’熱傳導構件2 0之表面上被覆有氧化防止膜， 因此可防止在亮燈中表面變得黯沈、光澤性降低的情形。 藉由上述之熱傳導構件20表面反射，熱傳導構件2〇抑制 了因光束照射之溫度上升，然而，因進行長時間照射及由 發光管12至反射器11之熱傳導，銅製之熱傳導構件2〇本身 的溫度會上升而產生熱膨脹。 如圖5所示，熱傳導構件2〇之各伸出部23至25的熱膨脹為 放射方向（直徑方向），然而，由於各伸出部23至25上設有曲 部23a至25a，因此直徑方向之膨脹被轉換成沿曲部23a至 25a之方向（圖中之黑箭頭方向），最終，膨脹份會成為與外 侧之肷合環狀部22之連結位置上之切線方向上之延展。依 此結果，可防止在被中央之外嵌環狀部21所外嵌之發光管 12上會被施加必要以上之由熱傳導構件2〇之熱膨脹所產生 之無用之應力，不會因發光管12之位移而發生光源裝置1〇 之光束之放射特性變化的情形，此外，亦不會發生發光管 12所包含之玻璃支撐體13藉由熱傳導構件2〇之熱膨脹而遭 到破壞的情形。 此外，本發明之投影型圖像顯示裝置丨及光源裝置1〇並不 限於上述方式，可適用種種之變形例。例如，投影型圖像 顯示裝置1中，亦可適用強制冷卻光源裝置1〇之冷卻風扇， 藉由如此般地適用冷卻風扇，可提高反射器丨丨之散熱性， 即使為了高亮度而進一步提高投入之電力纟，亦能確保穩 106371.doc -31 - 1277709 定地亮燈。此外，光源裝置10亦可省略防爆玻璃29而不支 援防爆規格。在此情況中，由於可對反射器11内送風，因 此，藉由與藉熱傳導構件20之熱傳導的搭配組合，可進一 步提高冷卻特性。 再者，光源裝置10之熱傳導構件20作為銅以外之材料， 亦適用熱傳導率良好之鋁等之其他金屬材料，金屬材料以 外亦適用氮化鋁所形成之陶瓷。此外，為了提高熱傳導構 φ 件20之表面之光澤性，除了施以鏡面研磨之外，以藉由電 鍍或蒸鍍等實施表面處理為佳。為了維持上述般之表面之 光澤性，除了如上述般以氧化防止膜被覆之外，在防爆規 - 格的情況中，亦可將氧化防止用氣體充填於反射器11内部。 此外，熱傳導構件20之各伸出部23至25的個數並不限於3 個，如為1個以上的話，個數並無限制。在此情況中，個數 愈少’可減少遮蔽反射器11所反射之光束的程度，而個數 愈多，則可提高熱傳導構件20之熱傳導性。 φ 再者’熱傳導構件20外側之嵌合環狀部22除了被嵌合於 反射器11之内圓面側之外，在光源裝置丨〇並非防爆規格 時’亦可為嵌合於外圓面側之構造。在此情況中，反射器 11可省略開口側之凸緣部丨lb，嵌合環狀部22不僅將内徑設 定成能嵌合於反射器丨丨之開口周緣之外圓面側的尺寸，並 藉由使嵌合環狀部22之寬度比各伸出部23至25之寬度還長 而设置礙合量的方式，以各伸出部23至25抵接於反射器11 之開口侧端面上之狀態，將嵌合環狀部22嵌合於反射器i i 之外圓面側亦可。 106371.doc -32- 1277709 再者’熱傳導構件20在構造上亦可省略外側之嵌合環狀 部22本身。如此一來，可更進一步簡化熱傳導構件2〇之構 造’有助於成本降低。在省略嵌合環狀部22的情況中，會 使各伸出部23至25之伸出端以直接與接觸器u内部接觸之 方式嵌合，惟亦可在反射器丨丨上設置用來與各伸出部23至 25後合之細縫之類的切槽，以提高各伸出部23至25與反射 器11之接觸性。 圖ό所示的為變形例之熱傳導構件3 〇。該變形例之熱傳導 構件30之特徵為在各伸出部33至35之中央之外嵌環狀部31 側上’亦設有曲部33d至35d。中央側之曲部33d之彎曲始點 33c為與光束密度高之區域r相交之距離τ之一側的點，因 此’不會以曲部33d妨礙到反射器11所反射之光束的密度高 之部分’此情形在其他曲部34d、35d亦同。如上述般地在 各伸出部3 3至3 5上分別設置外側及中央側之兩個曲部3 3 a 至35a、33d至35d，可進一步吸收熱膨脹所致之延展，而可 緩和熱膨脹之影響。此外，該變形例之熱傳導構件3〇中， 在因反射器11之形狀等而難以設置外側之曲部3 3 a至3 5 a 時’亦可省略外侧之曲部33 a至35a。 圖7(a)至（c)所示的為別的變形例之熱傳導構件4〇至6〇。 圖7(a)之熱傳導構件4〇係將中央之外嵌環狀部41及外側之 欲合環狀部42以直線形之伸出部43至45連結者，各伸出部 43至45並未設曲部。適用於如上述般之熱傳導構件4〇之材 料使用不易熱膨脹之陶瓷時之情況。 圖7(b)之熱傳導構件50係將由中央之外嵌環狀部51伸出 106371.doc -33- 1277709 1〇”係裝有發光管12之反射器11上設有變形例之熱傳導構 件80者。變形例之熱傳導構件8〇之特徵為由中央之外嵌環 狀部81伸出之伸出部83、84 (未圖示第三個伸出部）及外側 之嵌合環狀部82之寬度尺寸W設成在不與區域汉相交的範 圍内比圖3所示之熱傳導構件2〇還長。如此一來，伸出部 83、84之與伸出方向上垂直之剖面積可比圖3所示之熱傳導 構件20之各伸出部23、24還大，進一步提升熱傳導效率。 φ 圖9所示的為非防爆規格之變形例之光源裝置100，該光 源裝置100係在裝有發光管12之反射器u，上設置變形例之 熱傳導構件90者。變形例之熱傳導構件9〇並未被覆整個發 光官12之封裝部13，而改在突出侧之端部13b附近設置具有

材料所形成時，亦可不由發光管12之突出側之鉬箔17來使 引腳線伸出，而改在伸出部94上設置與鉬箔17導通接觸之[ 字形之接觸部96，經由外側之嵌合環狀部92之嵌合位置上 所設之反射器11’之孔部llj，而使引腳線d3及嵌合環狀部92 接合。如此一來，可將熱傳導構件9〇利用作為對發光管12 之引腳線之一部分，有助於光源裝置1〇〇之配線構造之簡 106371.doc -35- 1277709 化0 圖10(a)所示的為本發明之光源裝置所適用之變形例之反 射器111。變形例之反射器111之特徵為凹面鏡丨丨la之内圓 面11 If以熱擴散膜115被覆，以提升反射器U1之熱擴散性。 該熱擴散膜115為三層構造，由内圓面mf侧具有紅外線熱 轉換層112、光澤緩衝層113、及可見光反射層114。 紅外線轉換層112係以陽極氧化内圓面mf之方式成 膜’吸收通過可見光反射層U4及光澤緩衝層113之波長區

In addition, in the light irradiated by the light source device 1 ,, a part of the light is blocked by the extension portions 23 to 25 due to the presence of the heat conduction member 2, and therefore, a shadow is generated in the portion. However, in the projection Image display device, as shown in Figure 1, The light irradiated by the light source device 10 is incident on the cylindrical lens 3', and therefore, by the total reflection by the cylindrical lens 3, the ', , and the degree of light passing through the cylindrical lens 3 are uniformized. The extension portion 23&25^彡+ of the heat conducting member is not projected. The shadow will not be displayed on the projected image. In addition, the temperature of the glass building body (10) will be the temperature of the embodiment. In the light source device 10, there are two ways of dissipating heat in the light source device. Among the three methods, the most efficient one is heat transfer and the other is radiation. The following descriptions are all parties 106371.doc -28 - 1277709 The heat movement in the formula. The convective heat transfer is carried out by two systems, the two systems comprising: one for transmitting heat from the arc tube 12 to the reflector 11 via the air enclosed in the reflector 11 present around the arc tube 12; One is that heat is transmitted from the arc tube 12 to the explosion-proof glass 29 via the air existing around the arc tube 12. Furthermore, the radiation is carried out between the arc tube 12 and the reflector 1]L. There is a two-lane thermal path in the heat conduction, and the first heat path φ is heated by the light-emitting tube 12 to become one end portion 13a of the mounting side of the reflector 11, and is conducted to the reflector via the fixing agent 18. By. In addition, the above-mentioned convective heat transfer, radiation, and heat transfer of the first heat path are also seen in the conventional explosion-proof light source devices. The second heat path of the heat conduction is characterized by the light source device 1 of the present invention, which conducts heat through the heat-conducting member 20 through the package portion 13d of the light-emitting tube 12 on the protruding side of the lamp chamber portion 13c. To the reflector. The temperature of the light-emitting tube 12 in the lamp chamber portion 13c is the highest, and the heat of the lamp chamber portion 13c is transmitted to the package portion 13d on the protruding side, and the temperature of the package portion 13d rises, but in the light source device 10 of the present invention The heat of the package portion i3d is transferred to the reflector U via the heat path of the heat conduction member 20, and the temperature rise of the package portion Ud is suppressed, thereby prolonging the life of the light-emitting tube 12. In particular, in the present embodiment, the central portion of the heat conducting member 2A is fitted with the annular portion 21 in the vicinity of the lamp chamber portion 13c, and the package portion ud is externally fitted, and the package and the d and the outer portion are sufficiently contacted. The area is such that the heat transferred from the lamp chamber portion (5) which becomes the high temperature to the package portion 13d is efficiently moved to the outer ring portion 21 (the heat conduction member 20). Further, the movement to the outer annular portion 106: 106371.doc -29- 1277709 is moved in the extending direction via the extending portions 23 to 25 in the three directions to move to the outer fitting annular portion 22. The heat of the fitting ring portion 22 that has moved to the outside via the projecting portions 23 to 25 is then moved to the reflector 11 via the fitting surface iig that is in contact with the fitting annular portion 22. Further, the thermal movement from the package portion 13d of the arc tube 12 to the reflector 11 via the heat conduction member 20 as described above starts when the package portion 13d is higher than the heat conduction member 20 and the reflector 11, and proceeds to the package portion 13. (The temperature of 1 is lower than that of the heat conducting member 20 and the reflector 11. Further, the package portion 13d of the arc tube 12 is fitted to the outer side of the annular portion 21 so as to be closer to the lamp chamber portion 13c. By setting the mode, the heat dissipation property to the lamp chamber portion 13c can be increased, and conversely, the more the lamp chamber portion 13c is disposed, the more the heat dissipation can be improved for the package portion 13d. The reflector 11 itself has heat dissipation characteristics. Therefore, the heat transferred from the light-emitting tube 12 is finally radiated by the reflector 11. Therefore, the light-emitting tube 12 is cooled by the heat-conducting member 20, and the temperature of the lamp chamber portion 13c which becomes high in the lighting is suppressed to 800 ° C to 1000 ° Below °C, the temperature of the package portion 13d on the protruding side is surely suppressed to 400 ° C or less. Therefore, the electric arc tube 12 can be supplied with electric power of more than 200 W exceeding the upper limit of the conventional explosion-proof gauge of 150 W, in the present embodiment. Light source device 10 except In addition to the path of the heat-dissipating member 20 in the past, there is a path through the heat-conducting member 20, so that the light-emitting tube 2 can be maintained at the above temperature in the lighting, and the power is 200 W or more. On the other hand, in the lighting of the light source device 1, the heat conducting member 20 (especially the protruding portions 23 to 25) is irradiated with the light beam reflected by the reflector 11, but the heat conducting structure 106371.doc - 30- 1277709 The surface of the member 20 has been ensured to be lustrous by grinding, and therefore, the light beam of the irradiation is reflected by the surface to reduce the heat absorption rate of the heat conduction member 20 (projecting portions 23 to 25). Further, the heat conduction member 20 Since the surface is covered with the oxidation preventing film, it is possible to prevent the surface from becoming dull and the glossiness is lowered during lighting. By the surface reflection of the heat conducting member 20 described above, the heat conducting member 2〇 suppresses the temperature rise due to the beam irradiation. However, due to long-time irradiation and heat conduction from the arc tube 12 to the reflector 11, the temperature of the copper heat-conducting member 2 itself rises to cause thermal expansion. As shown in Fig. 5, the heat-conducting member 2 The thermal expansion of each of the projecting portions 23 to 25 is a radial direction (diameter direction), however, since the curved portions 23a to 25a are provided on the respective projecting portions 23 to 25, the expansion in the diameter direction is converted into the curved portion 23a. In the direction of 25a (the direction of the black arrow in the figure), eventually, the expansion portion is extended in the tangential direction to the joint position of the outer annular portion 22. As a result, it is prevented from being outside the center. The unnecessary light generated by the thermal expansion of the heat conducting member 2 is applied to the arc tube 12 embedded in the annular portion 21, and the light beam of the light source device 1 is not generated due to the displacement of the light emitting tube 12. In the case where the radiation characteristics are changed, the glass support 13 included in the arc tube 12 is not damaged by the thermal expansion of the heat conduction member 2 . Further, the projection type image display device 丨 and the light source device 1 of the present invention are not limited to the above-described embodiments, and various modifications are applicable. For example, in the projection type image display device 1, a cooling fan that forcibly cools the light source device 1 can be applied. By applying the cooling fan in such a manner, the heat dissipation of the reflector can be improved, and the brightness can be further improved even for high brightness. After the power is turned on, it can also ensure the steady lighting of 106371.doc -31 - 1277709. Further, the light source device 10 can also omit the explosion-proof glass 29 without supporting the explosion-proof specifications. In this case, since the air can be blown into the reflector 11, the cooling characteristics can be further improved by combining with the heat conduction by the heat conducting member 20. Further, the heat conduction member 20 of the light source device 10 is made of a material other than copper, and is also suitable for other metal materials such as aluminum having a good thermal conductivity, and a ceramic formed of aluminum nitride is also used as the metal material. Further, in order to improve the glossiness of the surface of the heat conduction member 20, it is preferable to perform surface treatment by electroplating or vapor deposition in addition to mirror polishing. In order to maintain the glossiness of the surface as described above, in addition to the oxidation preventing film as described above, in the case of an explosion-proof gauge, the gas for preventing oxidation may be filled in the inside of the reflector 11. Further, the number of the projecting portions 23 to 25 of the heat conduction member 20 is not limited to three, and if it is one or more, the number is not limited. In this case, the smaller the number is, the less the degree of the beam reflected by the reflector 11 can be reduced, and the more the number, the higher the thermal conductivity of the heat conducting member 20. φ Further, the fitting annular portion 22 on the outer side of the heat conducting member 20 may be fitted to the outer circular surface even when the light source device is not in the explosion-proof specification except that it is fitted to the inner circular surface side of the reflector 11. Side construction. In this case, the reflector 11 can omit the flange portion 丨 lb on the opening side, and the fitting annular portion 22 not only sets the inner diameter to a size that can be fitted to the circular surface side of the periphery of the opening of the reflector ,, Further, by setting the width of the fitting annular portion 22 to be longer than the width of each of the projecting portions 23 to 25, the protruding portions 23 to 25 abut against the opening side end surface of the reflector 11. In the upper state, the fitting annular portion 22 may be fitted to the outer surface of the reflector ii. 106371.doc -32- 1277709 Further, the heat conducting member 20 may be omitted in construction from the outer fitting annular portion 22 itself. As a result, the structure of the heat conducting member 2 can be further simplified to contribute to cost reduction. In the case where the fitting annular portion 22 is omitted, the projecting ends of the projecting portions 23 to 25 are fitted to be in direct contact with the inside of the contactor u, but may be provided on the reflector 丨丨Grooves, such as slits that are joined to the respective projecting portions 23 to 25, to improve the contact between the projecting portions 23 to 25 and the reflector 11. The heat conduction member 3 变形 of the modification is shown in FIG. The heat conduction member 30 of this modification is characterized in that the curved portions 31d to 35d are also provided on the side of the annular portion 31 outside the center of each of the projecting portions 33 to 35. The bending start point 33c of the curved portion 33d on the center side is a point on the side of the distance τ where the region r of the beam density is high, so that the density of the light beam reflected by the reflector 11 is not hindered by the curved portion 33d. Part 'This situation is the same in other songs 34d, 35d. As described above, the two curved portions 3 3 a to 35a, 33d to 35d on the outer side and the center side are respectively provided on the respective projecting portions 3 3 to 35, and the elongation due to thermal expansion can be further absorbed, and the thermal expansion can be alleviated. influences. Further, in the heat conduction member 3A of the modification, when it is difficult to provide the outer curved portions 3 3 a to 3 5 a due to the shape of the reflector 11 or the like, the outer curved portions 33 a to 35 a may be omitted. 7(a) to (c) are heat conduction members 4A to 6A of other modifications. The heat conducting member 4 of Fig. 7(a) has a central outer annular portion 41 and an outer annular portion 42 joined by linear projections 43 to 45, and each of the protruding portions 43 to 45 There is no song. It is suitable for the case where the material of the heat conducting member 4 as described above is used as a ceramic which is not thermally expandable. The heat conducting member 50 of Fig. 7(b) is extended from the center outer annular portion 51. The heat conducting member 80 of the modified example is provided on the reflector 11 in which the light emitting tube 12 is mounted. The heat-conducting member 8A of the modification is characterized in that the projecting portions 83, 84 (not shown in the third projecting portion) and the fitting ring-shaped portion 82 on the outer side are protruded from the center-integrated annular portion 81. The width dimension W is set to be longer than the heat conducting member 2A shown in Fig. 3 in a range that does not intersect the region Han. Thus, the cross-sectional area of the projecting portions 83, 84 perpendicular to the extending direction is comparable. The respective projecting portions 23, 24 of the heat conducting member 20 shown in Fig. 3 are large, and the heat transfer efficiency is further improved. φ Fig. 9 shows a light source device 100 according to a modification of the non-explosion-proof type, which is equipped with a light-emitting device. The reflector u of the tube 12 is provided with the heat-conducting member 90 of the modification. The heat-conducting member 9 of the modification does not cover the package portion 13 of the entire illuminating unit 12, but is provided with a coating in the vicinity of the end portion 13b of the protruding side. An outer annular portion 91 having a length of the encapsulation portion nd protrudes from the outer annular portion 91 The portions 93 and 94 (the third projecting portion is not shown), and the outer fitting end portion 92 is provided at the projecting end. The heat conducting member 9 of the modified example has the annular portion 91 and the outer portion. Since the widths of the projecting portions 93 and 94 and the fitting annular portion % are the same, it is easy to manufacture, and the heat transfer can be concentrated by the end portion 13b of the package portion 13 of the light-emitting tube 12 having the worst heat resistance. When the heat conducting member 9A of the modified example is formed of a material having electrical conductivity, the lead wire may not be protruded by the molybdenum foil 17 on the protruding side of the arc tube 12, but may be changed to the protruding portion 94. The contact portion 96 that is in contact with the molybdenum foil 17 is provided with the hole portion llj of the reflector 11' provided at the fitting position of the outer fitting annular portion 92, so that the pin line d3 and the embedded portion are provided. The annular portion 92 is joined. In this way, the heat conducting member 9 can be utilized as a part of the pin line of the light-emitting tube 12, which contributes to the wiring structure of the light source device 1 106 106371.doc -35 - 1277709 Fig. 10(a) shows a reflector 111 according to a modification of the light source device of the present invention. The emitter 111 is characterized in that the inner circular surface 11 of the concave mirror Ifla is covered with the thermal diffusion film 115 to enhance the thermal diffusivity of the reflector U1. The thermal diffusion film 115 has a three-layer structure and has an inner circular surface mf side. The infrared heat conversion layer 112, the gloss buffer layer 113, and the visible light reflection layer 114. The infrared conversion layer 112 forms a film which absorbs light passing through the wavelength region of the visible light reflection layer U4 and the gloss buffer layer 113 by anodizing the inner circular surface mf. In addition, the gloss buffer layer U3 is formed by forming a film of a Si-based resin or a polyimide-based resin at a high temperature on the infrared heat conversion layer 112 to prevent the infrared ray conversion layer 112 and the visible light reflection layer 114. Direct contact as a buffer for both. The visible light reflecting layer U4 is formed on the gloss buffer layer 113 to reflect visible light. Therefore, since the reflector 111 of the modified example has the thermal diffusion film 115 having the above-described laminated structure, even if the light beam emitted from the arc tube 2 is reflected, heat can be efficiently diffused to prevent deterioration of the reflecting surface.
