Description

1239549 V. Description of the invention (1) The technical field to which the invention belongs The present invention relates to a short-arc discharge lamp, which is used to complete the radiation process of a light source on a semiconductor wafer, a liquid crystal panel and an electric printing board, and particularly relates to a device having a Light source device for this short arc discharge lamp. In the conventional short-arc discharge lamp of the prior art (refer to the short-arc discharge lamp described later), in order to connect the discharge lamp to the lamp of the light source device, a fixed metal or an electronic connection metal (refer to the metal cover mentioned later) ) It is usually fixed to the two-end sealed tube of the cold light tube of the discharge lamp by a fixing material, and is made into a cylindrical shape. Furthermore, the cylindrical metal cover fixing portion (projecting portion) is located at the end portion of the metal cover, and a recessed portion is located at the lamp to define the position. This device is used to prevent tension from being applied to the wire, which is connected by the discharge lamp when the discharge lamp is connected to a lamp or a light-emitting connection. When the tension of the lead wire and the light-emitting connection portion increases, pressure will be applied to the discharge lamp, which will cause the discharge lamp to rupture, which will cause the accident that the light source of the discharge lamp cannot be switched and exploded. Similarly, the metal cover of the discharge lamp includes a connection portion (refer to the metal welding portion mentioned later), the gold derived from the electrodes inside the discharge lamp, and the wire for conducting electricity from the outside are connected by the connection portion. connection. The metal sheet φ is sealed with a sealing structure formed between the inner surface of the sealing tube and the outer surface of the supporting cylinder. The sealing tube is at both ends of the cold light tube of the discharge lamp, and the supporting cylinder is made of quartz. The two ends of the cold light tube of the discharge lamp and the electrodes are used to support the inside of the sealed tube, and the tail of the metal sheet is exposed

1239549 V. Description of the invention (2) In the environment inside the metal cover. Furthermore, when the discharge lamp is turned on, heat radiation is generated, and the temperature of the metal cover is about 300 to 400 ° C. Therefore, if the discharge lamp is not cooled when it is lit, the metal welded portion will be oxidized, or the end surface of the metal piece will be oxidized, and cracks will be generated on the support cylinder of the sealed pipeline made of quartz. Therefore, there is a danger that the lamp cannot be lit and burst. Conventional lamps include a nozzle to provide cooling gas so that the nozzle sprays to reduce the temperature of the inner metal weld or metal piece. Similarly, a method is used to directly cool the end of the metal weld or metal piece. There are two openings on it. The included angle is placed on the side of the metal cover 'and is perpendicular to the axis of the discharge lamp, or four 90. Included angle = opening, through which air or other gas is introduced into the metal cover. However, 'the cooling method of the surface of the metal cover mentioned above produces a cold inner part with poor efficiency and insufficient cooling due to the discharge: it is filled with a predetermined material, which is to fix the metal cover to the discharge. The internal and direct cooling method uses the side of the metal cover. When opening holes to cool the lamps into the lamp: comparison is a better method, but when opening the holes. Install the nozzle of cooling gas accurately on the metal cover

However, the work that has been done in the past requires the t lamp to have no positioning mechanism. The nozzle and the opening of the metal cover are fixed, and the two workers are in the above-mentioned cylindrical metal cover or the discharge lamp is connected to the lamp axis perpendicularly. The cross-sectional shape is circular, and the orientation is not completed, for example, with the discharge lamp

1239549 V. Description of the invention (3) For the rotation direction gap, and the metal opening is based on the phase cooling capacity of the electric lamp, the lamp cannot be lit anymore, the lamp must be increased, and the discharge lamp of the present invention will not be a problem. The same lamp without additional The size of the electric lamp shrinks and the positioning cover cools to the right position. Therefore, even if the cooling power is bright and burst, the cooling power is completely connected incorrectly. Therefore, the gas does not line up, and there is a possibility of explosion. The above-mentioned ability is used in accordance with the above error. If the light source is not installed, the cooling energy and power consumption are reduced, and the nozzle foot will be cooled outside the discharge. Method, it is inevitable to increase the lamp problem ’will be placed in the lamp, the amount of the ° and the position will be generated between the opening. In addition, because the cooling efficiency is not good and sufficient cracks cannot be generated on the lamp, the discharge will be avoided due to the increase in the heat of the discharge lamp. Therefore, the cooling capacity of the fixture of this lamp is related. The object of the present invention is to provide a fixture that is damaged, ruptured, and exploded in an electric lamp.

Similarly, since a plurality of openings are provided on the side of the metal cover of the discharge lamp at opposite positions, the time for introducing the cooling gas into the metal cover becomes longer. In order to solve the above-mentioned problem, according to item 2 of the scope of patent application of the present invention, the short-arc discharge lamp of the present invention has a plurality of openings for introducing or discharging a cooling gas. In the above case, there are two opposite openings on the side of the metal cover, and the cooling air introduction time of the metal cover will be the longest. In order to overcome the above-mentioned problems, according to the present application-the third scope of the patent application, the short arc discharge lamp of the present invention includes a position connection portion formed with a predetermined and unique projection or depression on the circumference of the metal cover fixing portion 14. On the surface. Through the above combination, when a discharge lamp is connected to a luminaire (set °), the connection direction or lighting condition of the discharge lamp is improved. In order to solve the above-mentioned problem, according to item 4 of the patent application scope of the present invention, the light source device of the present invention includes a lamp having a discharge lamp as described in the patent application scope items 1-3. The lamp includes a metal cover fixing frame having a recessed portion which can be connected to at least one metal cover fixing portion of an anode or a cathode of a discharge lamp; and a gas supply device located at a position opposite to an air conduction opening, the opening is formed at The side of the anode or cathode of the discharge lamp is fixed to a metal cover fixing frame.

As shown in FIG. 3, the position connection portion Hb is a side of the metal cover fixing portion 14 that is cut into a cylindrical shape. The formation of the cutting plane portion is not limited to this form. For example, the cross-sectional style of the metal cover fixing portion 14 is shown in the list in FIG. 7, where the cross-section is perpendicular to the axial direction of the discharge lamp. The cross-sectional style of the metal cover fixing portion 14 of the present invention may be A 2 to A 9. However, as long as 'the position where the discharge lamp 1 is connected to the above-mentioned lamp can be defined', any shape is possible. Similarly, the section style can determine the only connection position. In other words, as in the table, the section style must be at least one of the top and bottom or left and right sides. The shape is different when flipped upside down, or the outer ridges overlap when the profile profile is flipped left and right according to the center line γ. In other words, if the two axes of the discharge lamp in Figure 3 are set to be opposite axes, that is, the Z-axis is rotated by a predetermined angle, then the cross-sectional pattern must become rotationally asymmetric and

2036-5481-P (Nl) .ptd Page 12 1239549 V. Description of the invention (July) No overlap occurs. Furthermore, the metal cymbal fixing portion 14b is preferably a connecting portion formed with a predetermined and unique projection or depression on the peripheral surface of the metal cover fixing portion 14 (such as A3 to A9 in the list in FIG. 6), and The metal cover fixing portion 14 is connected to the recessed portion 27 of the metal cover fixing frame 26 of the lamp 21. Bite-The sealed tube on the anode (not shown) side is also composed of the sealing member 4 on the cathode 3 side, and the same position connection part 1 4b is also formed on the cathode 3 # or the metal lid fixing part on the anode side 丨4 At least one of the circumferences, κ, and when both the cathode 3 and the anode have both ends, they need to be made different from each other to achieve the situation where the discharge lamp emits light in the same direction.

As shown in FIGS. 1 and 3, a plurality of openings 11a and lib are formed on the side of the metal cover 11 'The positions where these openings 11a and lib are formed are not arranged in a relative manner' so that cooling can be achieved due to the discharge lamp A metal cover 11 that emits light and generates heat at a high temperature. One of the openings 1 la and 1 lb is an inlet air opening 1 ia, and the other opening and the opening 1a are arranged in a non-opposed manner, and the air outlet opening 11 b is provided.

Page 13 1239549 V. Description of the invention (8) B4 to B6 are taken as an example, but it is not limited to this setting. As shown in the shape of B5 on the table, cold air stays in the metal cover 11 for the longest time. Good cooling effect. In addition, the number of openings on the metal cover used for the anode (not shown in the figure) and the cathode can be different. In addition, the fixing material 13 is filled between the metal cover η of the discharge lamp 1 and the sealing tube 4, and the plurality of openings 丨 丨 a and 丨 丨 b on the side of the metal cover 1 1 are not blocked, and are fixed. The material of material 1 3 is not particularly limited, as long as it can be tightly connected, sealed, and not deteriorated at high temperatures. As described above, the discharge lamp 1 has a position connection portion 14b, so that the metal cover 14 of the discharge lamp 1 can specify the connection position, and because the connection portion (position connection portion 14b) is a convex portion or a concave portion formed on the metal cover for fixing The circumferential surface of the portion η becomes the only predetermined connection position. This—the cross-sectional pattern of the metal cover fixing portion 14 is at least one of up and down asymmetrical or left and right dissymmetrical (rotational disproportion), so that the connection direction of the discharge lamp 1 becomes a discharge The connection of the lamp 丨 the only direction when the fixture is installed, the positional correspondence between the air supply device on the luminaire and the opening 11a for introducing air on the metal 得以 11 can be changed, = there is no gap between the two '. Therefore, the cooling air effectively passes through The opening of the hole is introduced, and the cooling efficiency of the metal cover 11a can be improved. Then, the work rolling is derived from the opening m that is not opposite to the lead air opening lla, and the convection in the cooled empty metal cover η is introduced through the two openings (the air conduction in the metal cover is 1p / charging when the air conduction continues). The knife has more cooling efficiency in adding metal J3IL 1 1.

2036-5481-P (Nl) .ptd Page 14 1239549 V. Description of the invention (9) Furthermore, the fixing material 13 does not block the openings Ua and nb, so that it will not affect air conduction, so it will not reduce the introduction of metal The air flow rate of the cover n, and this function is different from the thermal insulation material of the conventional discharge lamp, so that the cooling efficiency in the discharge lamp 11 can be improved. Therefore, the improvement of the cooling efficiency inside the discharge lamp 11 can improve the problem of insufficient cooling. It can also solve the problems of failure to open and close, damage, burst, and short life of the discharge lamp. Furthermore, through the connection portion (position connection portion 14b), The form of the convex portion or the concave portion is formed on the circumferential surface of the metal cover fixing portion 14 = to be the only predetermined connection position, and the metal fixing portion 14 has a cross-section = asymmetry (rotation is not the only name) #at least up and down does not Symmetrical or left-and-right form 'When the discharge lamp li4 is connected to the lamp, the polarity connection is incorrect 4:: 2: The wrong polarity connection of the dagger will cause the top of the negative pole to light up ^', the required deduction, which will make the discharge lamp 1 Has a shorter life. The light source device 20 shown in FIG. 2 includes a discharge lamp 1 and two 2 ^ 拄 拄 φ ι Ι connected to the lamp 21. The lamp 21 is connected to the plate 22, 23 with a metal cover Hi, and connected to the element by the discharge lamp 25 The lower part of the metal cymbal holder 26 fixes the discharge lamp i. A “3” must be located at least on the anode or cathode of the discharge lamp 1 on the solid part U, more precisely, The only side surface of the connection portion on the fixed metal cover fixing frame 26 is connected to the outer shape at Μ 厘. Of course, the cross-sectional pattern of the Φ μ-metal 盍 fixing part H of this connection position is preferably as shown in FIG. 3 and # 于 + Μ—No, but in FIGS. 3 and 4, the bump of the recess 27 is 27a is formed on the metal cover fixing frame 26, and is formed outside the metal cover fixing portion 14;

1239549 V. Description of the invention (10) The shape of the fitting groove 14a is matched, and the position connection portion 14b of the metal cover fixing portion 14 is a fixing element 28 fixed to the metal cover fixing frame μ. Furthermore, the metal cover fixing portion The fitting groove i4a of 14 is fixed by screws through the spring tip 2 7 b and the hole 2 7 c of the metal cover fixing frame 2 6. Similarly, as shown in FIG. 2 and FIG. 5, the lamp 21 includes gas nozzles 29 a and 30 a as a gas supply device to supply gas for cooling the discharge lamp 1 and metal caps 1 and 1 on the anode and the cathode. . The tip of each nozzle is provided with an opening 11a for conducting air. This opening is formed on the side surfaces of the metal covers 11, 11 of the anode and cathode, and the cooling gas is ejected therefrom. Therefore, the cooling gas is introduced into the metal cover 11 and the metal cover 丨 丨 is cooled from the inside. The positional relationship of the nozzles 2 9 a and 30 a is based on the position of each of the openings for conducting air on the side of the metal lids 11 and 11 of the anode or cathode, and can be translated with the discharge lamp 1 as the rotation direction. For example, the positional relationship of the nozzles 29a, 30a is translated by 180 degrees in Fig. 5c. As shown in Figures 5a and 5b, the top positions of each nozzle 29a, 30a are not appropriately close to the outer surface of the metal cover as shown in Figure 5a, as shown in Figure 5b. The illustrated insertion into the metal cover η may depend on the cooling efficiency. Similarly, the cooling method may be appropriately selected from a method of providing a plurality of individual nozzles 29a and 30a, or a method of cooling the metal cover 11 from the outer surface of the metal cover 11 by spraying cooling gas on the surface of the metal cover. , Can be determined according to the cooling rate. Similarly, the cooling flow rate of the cooling gas (c00Hng fiu ^ is set at 50-30 mL / min, and other cooling gas can also be used to take the cooling gas. Furthermore, the lamp 21 includes a reflector 31 to collect the work Discharge

. The reflected light (such as a semiconductor silicon wafer), the cooling device 32 is used to cool the reverse: 31 and the cover plate 33, and the cover plate 33 is used to block the heat of the reflector. The light source device is located at the bottom of the connection plate 33. In 20, the recess j27 of the metal cover fixing frame 26 of the lamp 21 is made connectable to the metal cover fixing portion 14 of the discharge lamp 1, so that there is only one connection direction of the auxiliary discharge lamp 1, and the nozzles "^, 3〇" The position of a: The presentity can be regarded as the gas supply device of the lamp 21 and the guiding gas openings on the gold cover 11 of the discharge lamp 1 丨 a, 丨 1 a has been improved. Therefore, the position gap therebetween will be It will not exist, and the cooling rate in the metal caps ila and ila is also improved. In addition, the cooling efficiency in the metal caps i ii i is maintained by the nozzles 29a and 30a, and the positions of the nozzles 293 and 30a are Opposite to the openings 11a, 11a for guiding the gas. Since the cooling efficiency in the metal covers 11 and 11 is improved as described above and maintained, the discharge lamp of the lamp 21 with the use of high light 丨 its cooling capacity is not required Increasing 'can reduce it, but can reduce the size of the device to Small electricity consumption. Further, the light emitting position of the discharge lamp 1 is also in a single direction, and the reduction of the service life of the discharge lamp due to the wrong polarity connection can be avoided. Next, the present invention will be described with specific embodiments. However, the present invention is not limited to this embodiment. The discharge lamp of the present invention is a short-arc discharge lamp in a cold light tube with an outer diameter of 82 cm. The length of the cold light tube is 7 cm, and it is surrounded by mercury of 20 mg / CC. The electric power is 5 kW, the discharge watt is 50 volts, and the discharge current is 100 A. The cathode is used as the lighting position and the metal cover fixing part of the lamp is provided on the cathode.

2036-5481-P (Nl) .ptd λΓΤΓ Le 17 page 1239549 V. Description of the invention (12) First embodiment When the discharge lamp is connected to a luminaire, in order to be able to calculate the reproducibility of the connection position, the discharge lamp has A1 to A9 Wait for nine different styles of the metal cap fixing part of the cathode. Ai to A9 styles of the metal cover fixing part of the cathode of the discharge lamp See the list in Figure 7. In addition, the discharge lamp patterns A 丨 are conventional, and A2 to A9 are patterns of the present invention. The discharge lamp metal cover pattern A1 is made without a position connection portion to explain the connection position of the discharge lamp. The discharge lamp metal cover styles 2 to 8-9 have position connection portions to explain the connection position of the discharge lamp. Similarly, an opening for guiding air for cooling is provided on the surface of the metal cover at the same size as the tail end. The measurement is performed in the following manner. First, prepare nine types of discharge lamps A1 to A9 according to the lamp. The discharge lamp is connected to the lamp several times to check whether the opening of the conductive air on the surface of the metal cover can be opposite to the position of the gas nozzle of the lamp. (This position reproducibility will be explained later.) This result is shown in the list in Figure 7. The list in Figure 7.

According to the measurement results, the discharge lamp A1 (the conventionally known discharge connection ί ΐ Ϊ = and the problem that the position cannot be reproduced 'is because the discharge lamp uses the eye-pitch electricity "axially" the position of the gas conduction opening and the gas nozzle ... discharge The lamp A2 (the discharge lamp of the present invention) has two position connection portions (

1239549 V. Description of the invention (13) The side part is the same size as the metal cover fixing part part, with the lower sides, and there are two kinds of connection parts at this position (cut edge 饩 ^ ^ ^ ^. However, connecting this discharge When the lamp is on, check the exhaustion threshold. 0 «^ e ^ —The position of the body conduction opening and the gas nozzle can be obtained. The position reproducibility of the discharge lamps A3 to A9 is located in the current genus The discharge lamp of the pen ^ ^ month) has a position connection part ^ connection part of the metal i fixing part) with a convex bite recessed °, and a connection part (position determines the oblique stroke & w to position the metal cover fixing part has At least one kind of asymmetrical). Therefore, even if the discharge lamp is not connected to the inspection gas conduction opening and the gas nozzle, the position reproducibility of the gas conduction opening and the milk nozzle can be sufficiently accurately obtained. Second Example In the experiment where the value of 盍 is the internal cooling efficiency of 盍, the number of gas openings on the side of the metal cover and the six types of discharge lamps 81 are thin. In 盍, the temperature is used to compare with each other. The cooling system of the metal cover;-; ϊ :: ΐ: spray the cooling gas in one direction on the metal cover 'metal cover' 2: measure by the position of the galvanic rod (such as the outer guide connection 10 in Figure 1), The internal metal molybdenum and the inner lead are included in the and. This measurement is not shown in Figure 6. In addition, the discharge lamps B1 to B3 are conventional discharge lamps ^, and the discharge lamps B4 to B6 are the discharge lamps of the present invention. Electric lamp, the test result in the list in Figure 8 shows the discharge lamp B without openings (the conventional discharge lamp)

1239549 V. Description of the invention (14) The temperature in the metal cover is the highest # 'Furthermore, the discharge lamp M to the other (discharge lamp of this specification) has a lower metal cover inside than the discharge lamp B2 AB3, the original reason It is a conventional opening for introducing gas and an opening for introducing gas whose positions are opposite. It is introduced into the metal cover by the introduction of the gas opening, and the cooling gas does not take away the heat inside the metal cover. It will be discharged through the opening of the outlet gas. As a result, the cooling efficiency inside the metal cover becomes worse. In other words, the discharge lamps B4 and B6 (discharge lamps of the present invention), the openings for the outlet gas and the openings for the introduction of the gas are not in opposite positions. Therefore, the convective cooling gas is in the discharged gas. It can absorb enough heat before it is discharged. In order to check the above situation, the temperature of the cooling gas discharged from the discharge lamp metal cover B2 (the conventional discharge lamp) and the discharge lamp metal cover β5 (the discharge lamp of the present invention) (through the opening of the derived gas) is measured. 'When the cooling flux of the cooling gas is 100L / min, the temperature of the discharged cooling gas shows the discharge lamp B5 (discharge lamp of the present invention) compared to the discharge lamp B2 (the conventional discharge lamp) ) About 45. 〇. The above results show that the cooling efficiency in the metal cover can be effectively improved by providing a plurality of openings on the side of the metal cover or arranging the outlet gas openings and the introduction gas openings in opposite positions, and furthermore, the cooling flow rate For example, the influence of the cooling flow rate is reduced to 1/2 or less (in the present invention, the internal temperature is 160 ° C at a cooling flow rate of 50 L / min), compared with the conventional metal cover (cooling in the conventional The internal temperature is 17 5 ° C at a flow rate of 100 L / mi. As described above, the short solitary discharge lamp of the present invention includes a position connection portion for defining the connection position of the metal cover fixing portion at at least one anode or cathode.

2036-5481-P (Nl) .ptd Page 20 1239549 V. The circle of the invention description (15) " " also includes a plurality of openings arranged in a non-relative manner, which are located at the 1% pole or cathode Side of the metal cover. Therefore, the cooling efficiency can be improved when the reliable positioning work of the cooling nozzle can be completed. Or the number of openings is two, and the position connection part is a connection part as the only predetermined position. The position is formed on the surface of the metal cover fixing part in a convex or concave form. The contribution of the present invention enables the discharge lamp not to belong to the cooling air due to the bad connection direction, nor to shorten the discharge due to the incorrect polarity connection U, "and the defect of the light emitting position. Furthermore, the above-mentioned discharge The lamp system is connected to a. A ^ The fixed frame can be connected to the metal cover of the discharge lamp = ^, eight, the metal cover should be installed in the phase of the device;; Phase 3 is connected: and the gas is fixed to the metal cover On the fixed frame. The conductive milk openings are used, and the cooling capacity of the discharge lamp does not need to be described. The lamp is accompanied by less highlights, which can reduce the size of the device. ^ Σ > The present invention has been disclosed in a preferred embodiment with a small power consumption. Limiting the present invention, anyone who is familiar with this technique can use it within the scope and spirit, but can still make a little ^ without departing from the present invention The scope of intensive care shall be treated as the attached application for exclusive use of Jinjin.
