Description
本發明係關於一種高壓氣體放電燈，特別是一種利用金屬箔以在燈管中形成一放電空間之高壓氣體放電燈。The present invention relates to a high pressure gas discharge lamp, and more particularly to a high pressure gas discharge lamp using a metal foil to form a discharge space in a lamp tube.
投影顯示器用的光源系統必須要有效率地將燈源發出的光集中在顯像元件上，投影機可以使用的燈源早期有鎢絲鹵素燈(TungstenHalogen Lamp)，現在較多使用的是金屬鹵化物燈(Metal Halide Lamp)、高壓氣體放電燈(high－pressure discharge lamp)及氙氣弧光燈(Xenon Arc Lamp)。The light source system for the projection display must efficiently concentrate the light from the light source on the developing element. The light source that can be used in the projector has a tungsten halogen lamp (Tungsten Halogen Lamp) in the early stage, and now more is used for metal halogenation. Metal Halide Lamp, high-pressure discharge lamp and Xenon Arc Lamp.
目前廣為使用的是高壓氣體放電燈(high－pressure discharge lamp)，其係為投影機或背投影電視最主要的關鍵零件，其發光它的原理是在水晶石英玻璃管內，以多種化學氣體充填，其中大部份為氙氣(Xenon)與鹵化物等混合惰性氣體，然後再經過燈管兩端的鎢電極產生高電壓的加壓電弧以激發石英管內的電子游離，並形成電漿態後以在兩電極之間產生光源，這就是所謂的氣體放電。Currently widely used is a high-pressure discharge lamp, which is the most important key component of a projector or a rear projection television. Its principle of illumination is in a quartz crystal glass tube with various chemical gases. Filling, most of which is Xenon mixed with inert gas such as halide, and then through the tungsten electrode at both ends of the lamp tube to generate a high voltage pressurized arc to excite the electrons in the quartz tube to dissociate and form a plasma state. To create a light source between the two electrodes, this is called a gas discharge.
然而一般在高壓氣體放電燈中，點燈時通常會有不容易點燈的情形產生。US6563267、US7329992、JP2003297287此3篇專利文獻都是為了解決這種情況。其中US6563267是利用密封燈管時，在金屬箔處形成空腔，而此空腔會產生紫外線並提高點燈效率；US7329992是將原來的金屬箔以電極電性連接，且電極處有線圈纏繞並形成空腔，此空腔會產生紫外線且能低壓點燈； JP2003297287為在金屬箔環繞線圈，使燈管在密封時產生少許空隙，此空隙能造成低壓點燈。However, generally in a high-pressure gas discharge lamp, there is usually a situation in which it is not easy to light up when lighting. US6563267, US7329992, JP2003297287 all three patent documents are to solve this situation. Among them, US6563267 uses a sealed lamp tube to form a cavity at the metal foil, and the cavity generates ultraviolet rays and improves lighting efficiency; US7329992 electrically connects the original metal foil with electrodes, and the coils are wound at the electrodes. Forming a cavity that generates ultraviolet light and can be lit at a low voltage; JP2003297287 is to surround the coil in the metal foil, so that the lamp tube generates a small gap when it is sealed, and this gap can cause low-voltage lighting.
本發明同樣揭露一種高壓氣體放電燈，其係改良高壓氣體放電燈之燈體，以在燈管結構中利用金屬箔形成一空間的方式，來解決不易點燈的情形，並增加其點燈之功效。The invention also discloses a high-pressure gas discharge lamp, which is to improve the lamp body of the high-pressure gas discharge lamp, so as to form a space by using the metal foil in the lamp tube structure, to solve the situation that the lamp is not easy to light, and to increase the lighting thereof. efficacy.

根據本發明之實施例之高壓氣體放電燈，其係將第一金屬箔及第二金屬箔之至少其中之一以捲繞或摺疊的方式形成一空隙，此一空隙在導電時能放電並產生紫外線而提高點燈之效率。另外在密封燈管時，由於金屬箔已由捲繞或摺疊方式形成空隙，不需為了在密封時形成一空間而改變密封的參數而造成封合的不穩。A high-pressure gas discharge lamp according to an embodiment of the present invention, wherein at least one of the first metal foil and the second metal foil is wound or folded to form a gap, and the gap can be discharged and generated when conducting Ultraviolet light increases the efficiency of lighting.

"Picture 1B" is an enlarged view of Part A of "Picture 1A". A discharge lamp tube 10 is included. The discharge lamp tube 10 is composed of a discharge chamber 11 and side tubes 12, 13 extending on both sides of the discharge chamber 11. The discharge lamp tube 10 has an elliptical glass bulb of quartz glass. The discharge chamber 11 is filled with at least one gas component, generally containing at least an inert gas, and further mixed with mercury or a mixture of metal halides selected from the group consisting of bromine or chloride and bromine/iodine mixed compounds. One of the groups.

The halogen element is preferably a bromine or chlorine compound or a bromine/iodine mixed compound.
放電燈管10還具有第一電極14與第二電極15，彼此 相對設置，其各有一端部延伸至放電腔11中。第一電極14與第二電極15通常是金屬材質，例如鎢或鎢合金。在一實施例中，第一電極14與第二電極15彼此相對並相距小於近2.0 mm以下。在另一實施例中，電極頭端前具有一電極尖端。The discharge lamp tube 10 further has a first electrode 14 and a second electrode 15, and each other The opposite ends each have an end portion extending into the discharge chamber 11. The first electrode 14 and the second electrode 15 are usually made of a metal material such as tungsten or a tungsten alloy. In an embodiment, the first electrode 14 and the second electrode 15 are opposite each other and are less than approximately 2.0 mm apart. In another embodiment, the electrode tip has an electrode tip in front of it.
側管12中設置有第一金屬箔16，第一金屬箔16連接第一電極14與從側管12向外延伸的第一金屬導線17。同樣地，側管13中設置有第二金屬箔18，第二金屬箔18連接第二電極15與從側管13向外延伸的第二金屬導線19。第一金屬箔16與第二金屬箔18分別以緊密真空的方式設置側管12、13中。電流係自外部透過第一金屬導線17、第二金屬導線19、第一金屬箔16與第二金屬箔18供應至第一電極14與第二電極15而產生光。此外，如『第2A圖』所示，根據本發明之實施例，為了方便連接金屬箔與金屬導線，可在第一金屬箔16之兩側以裁切的方式分別形成有兩個第一連接部16a、16b，以分別與該第一電極與該第一金屬導線連接；同樣地，可在第二金屬箔之兩側分別形成有兩個第二連接部18a、18b，以分別與該第二電極與該第二金屬導線連接。而如『第2B圖』所示，為了簡化製程，亦可以裁切的方式將金屬箔四個角落的部分保留，以形成連接部。A first metal foil 16 is disposed in the side tube 12, and the first metal foil 16 connects the first electrode 14 with a first metal wire 17 extending outward from the side tube 12. Similarly, a second metal foil 18 is disposed in the side tube 13, and the second metal foil 18 connects the second electrode 15 with a second metal wire 19 extending outward from the side tube 13. The first metal foil 16 and the second metal foil 18 are respectively disposed in the side tubes 12, 13 in a tight vacuum. The current is supplied from the outside through the first metal wire 17, the second metal wire 19, the first metal foil 16, and the second metal foil 18 to the first electrode 14 and the second electrode 15 to generate light. In addition, as shown in FIG. 2A, according to an embodiment of the present invention, in order to facilitate the connection of the metal foil and the metal wire, two first connections may be respectively formed on both sides of the first metal foil 16 by cutting. The portions 16a and 16b are respectively connected to the first electrode and the first metal wire; similarly, two second connecting portions 18a and 18b may be respectively formed on both sides of the second metal foil to respectively respectively The two electrodes are connected to the second metal wire. As shown in FIG. 2B, in order to simplify the process, portions of the four corners of the metal foil may be retained in a cut manner to form a joint portion.
本發明的特徵在於利用第一金屬箔16與第二金屬箔18之至少其中之一在側管中形成一空隙，此一空隙在導電時能放電並產生紫外線而提高點燈之效率。第一金屬箔16與第二金屬箔18兩者並非要同時形成空隙，可選擇性地讓兩者其中之一形成空隙即可。當然使第一金屬箔16與第二金屬箔18兩者都形成空隙 會對電燈效率的改善有較佳的效果。此處之金屬箔可由鉬製成。The present invention is characterized in that a gap is formed in the side tube by at least one of the first metal foil 16 and the second metal foil 18, and the gap can discharge and generate ultraviolet rays when conducting electricity to improve the efficiency of lighting. It is not necessary for both the first metal foil 16 and the second metal foil 18 to form a void at the same time, and one of the two may be selectively formed into a void. Of course, the first metal foil 16 and the second metal foil 18 are both formed into a gap. It will have a better effect on the improvement of the efficiency of the lamp. The metal foil here can be made of molybdenum.
以下說明請以金屬箔形成空隙的方式。參考『第2A圖』及『第2B圖』，在一實施例中，係將第一金屬箔16與/或第二金屬箔18以捲繞的方式形成一空間，進而在側管中形成一空隙。如『第3A圖』所示，金屬箔所形成之空間係為一密閉空間，而如『第3B圖』所示，金屬箔所形成之空間係為一非密閉空間。當金屬箔形成之空間係為一密閉空間時，金屬箔之一側係被包覆於該密閉空間中，以形成尖端161。In the following description, please use a metal foil to form a void. Referring to "2A" and "2B", in an embodiment, the first metal foil 16 and/or the second metal foil 18 are formed into a space by winding, thereby forming a space in the side tube. Void. As shown in FIG. 3A, the space formed by the metal foil is a closed space, and as shown in FIG. 3B, the space formed by the metal foil is a non-closed space. When the space formed by the metal foil is a closed space, one side of the metal foil is wrapped in the sealed space to form the tip end 161.
在另一實施例中，如『第4A圖』及『第4B圖』所示，係將第一金屬箔16與/或第二金屬箔18以折疊方式形成一空間，進而在側管中形成一空隙。圖中所示係折疊成三角形之空間，當然並非以三角形為限。同樣地，如『第4A圖』所示，金屬箔所形成之空間係為一密閉空間，而如『第4B圖』所示，金屬箔所形成之空間係為一非密閉空間。當金屬箔形成之空間係為一密閉空間時，金屬箔之一側係被包覆於該密閉空間中，以形成尖端162。透過『第3A圖』至『第4B圖』的設計，使得燈被啟動時，產生電場促使間隙內增加紫外線增強的作用，提高點燈率以及在點燈的過程中使熱能均勻化的目的。另外在密封燈管時，由於第一金屬箔16與/或第二金屬箔18可在燈管中形成空隙，不需為了在密封時形成一空間而改變密封的參數而造成品質的不穩定。In another embodiment, as shown in FIG. 4A and FIG. 4B, the first metal foil 16 and/or the second metal foil 18 are formed into a space in a folded manner, thereby forming in the side tube. A gap. The space shown in the figure is folded into a triangle, of course not limited to a triangle. Similarly, as shown in FIG. 4A, the space formed by the metal foil is a closed space, and as shown in FIG. 4B, the space formed by the metal foil is a non-closed space. When the space formed by the metal foil is a closed space, one side of the metal foil is wrapped in the sealed space to form the tip end 162. Through the design of "3A" to "4B", when the lamp is activated, an electric field is generated to increase the effect of increasing the ultraviolet rays in the gap, thereby improving the lighting rate and homogenizing the heat during the lighting process. In addition, when the lamp tube is sealed, since the first metal foil 16 and/or the second metal foil 18 can form a gap in the lamp tube, it is not necessary to change the parameters of the seal in order to form a space during sealing, resulting in quality instability.
請參考『第5圖』，係為本發明所揭露之高壓氣體放電燈之電極之一實施例。可在第一電極14伸至放電腔11中之端部前端具有一電極頭端，而該電極頭端141具有一電極尖端142。Please refer to FIG. 5, which is an embodiment of the electrode of the high pressure gas discharge lamp disclosed in the present invention. An electrode tip end may be provided at the end of the end portion of the first electrode 14 extending into the discharge chamber 11, and the electrode tip end 141 has an electrode tip 142.
此外，電極上亦可形成一層或多層由鎢或鎢合金製成的纏繞線圈143套入第一電極14的一端，接著纏繞線圈143的部份前端與第一電極14一起熔融以形成大體上為半球體、錐體或球體的電極頭端141。此纏繞線圈143與電極頭端141係用於讓電極14使用中所產生的熱量迅速傳遞出去，達到冷卻的效果，如此才能延長第一電極14的壽命與穩定性。In addition, one or more winding coils 143 made of tungsten or a tungsten alloy may be formed on one end of the electrode to be inserted into one end of the first electrode 14, and then a part of the front end of the wound coil 143 is melted together with the first electrode 14 to form substantially The tip end 141 of the hemisphere, cone or sphere. The winding coil 143 and the electrode tip end 141 are used to quickly transfer the heat generated by the use of the electrode 14 to achieve a cooling effect, so as to extend the life and stability of the first electrode 14.
同時，在對高壓氣體放電燈的亮度需求越來越高，也就是對於通過電極能量的需求越來越高的情況下，此電極間距的大小對氣體放電燈的性質有絕對性的影響，例如間距太小時，太高的能量通過會使得熱量過度集中，容易造成氣體放電燈燒毀等情形；反之，若間距太大，則會有收光效果不佳，影響光效的情況產生。因此，本發明將兩電極尖端間距配置小於1.5mm，而電極頭端間距配置在近1.3-2.0mm之間，以改善氣體放電燈的光效。At the same time, in the case of higher and higher requirements for the brightness of high-pressure gas discharge lamps, that is, in the case where the demand for energy through the electrodes is increasing, the size of the electrode spacing has an absolute influence on the properties of the gas discharge lamp, for example, If the spacing is too small, the energy passing too high will cause the heat to be excessively concentrated, which may easily cause the gas discharge lamp to burn out. On the contrary, if the spacing is too large, there will be a poor light collecting effect, which may affect the light effect. Therefore, the present invention arranges the tip spacing of the two electrodes to be less than 1.5 mm, and the electrode tip end spacing is disposed between approximately 1.3-2.0 mm to improve the luminous efficacy of the gas discharge lamp.
本發明所揭露之高壓放電燈之燈管中，將金屬箔捲繞或摺疊，在加熱密封燈管時，使前述金屬箔經捲繞或摺疊後形成一空隙，此一空隙在導電時能放電並產生紫外線，且能低壓點燈提高點燈之效率。另外本創作的金屬箔因捲繞或摺疊使得金屬箔變得立體而非一般的條狀，因此會增加金屬箔的強度，使金屬箔不容易彎曲，且在製程中不會因為金屬箔的抖動而影響電極的對稱，進而降低燈的亮度及壽命。In the lamp tube of the high pressure discharge lamp disclosed in the present invention, the metal foil is wound or folded, and when the lamp tube is heated and sealed, the metal foil is wound or folded to form a gap, and the gap can discharge when conducting. It also produces ultraviolet light, and low-voltage lighting can improve the efficiency of lighting. In addition, the metal foil of the present invention is made into a three-dimensional rather than a general strip shape by winding or folding, so the strength of the metal foil is increased, the metal foil is not easily bent, and the metal foil is not shaken during the process. It affects the symmetry of the electrode, thereby reducing the brightness and life of the lamp.
雖然本發明以前述之實施例揭露如上，然其並非用以限定本發明。在不脫離本發明之精神和範圍內，所為之更動與潤飾，均屬本發明之專利保護範圍。關於本發明所界定之保護範圍請參 考所附之申請專利範圍。Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention.
