The lamp i (Lamp) passes through the reflector 3 (KeflectOT)' and the spherical discharge region ia (Discharge Vessel) is placed on the inner surface of the reflector 3, and the light emitted from the discharge region 13 is concentratedly reflected forward by the paraboloid. , projecting forward through the headlight cover glass 4 (FnmtGlass). The discharge lamp tube 1 is made of quartz glass. The maximum safety of the outer casing is recommended for the endowment. The higher temperature will cause the acceleration of the quartz glass to be the life of the fresh discharge lamp. The electrode of the discharge lamp f] has its own limit, and the I wire electrode is taken as an example, and its softening is simple. C, so the discharge tube 1 lights the touch towel, and the electrode temperature _ leans on its life and function in the Wei point town. y, "put t (four) put the fruit temperature operation '_ and do not lack the upper limit of the operation of the Wealthy face =, and the spherical discharge of the touch 1 _ = 1 彳, the lower surface temperature must also be uniform ' and as much as possible ^ and / in the process of glazing, the convection effect of mercury vapor tends to cause the discharge = 6 1261858 to cause quartz breakage and the thermal method is effectively maintained, the temperature difference between the lower surface 1 and the temperature difference between the upper and lower surfaces is too large, resulting in too high temperature on the upper surface. , the bad, but the surface of the crucible is too low temperature 'forms the vapor condensation, the normal light, so the high-pressure gas discharge lamp must work in a very small upper range. Therefore, the high-pressure gas discharge lamp must have a cooling device that can control the temperature distribution. · At the same time, the high-pressure gas discharge lamp is maintained at a better operating temperature range to balance the work insult and the light-emitting efficiency. Traditionally, in order to operate the high-pressure gas discharge lamp in the reflector, the system manufacturer is one or more fans. The air is blown by the upper/lower side and the rear side of the reflector 3, and the airflow is transmitted by the "air gap" 3a (AirGap) on the front side of the reflector 3, and the cooling air is introduced into the anti-fresh 3β, which is also directly The outside of the reflector 3 is cooled. The air gap can be the aperture opened in the anti-fresh 3, and can also be a small gap reserved for the assembly of the front lamp cover glass 4 and the reflector 3 for gas circulation. However, the above-mentioned method has the following disadvantages: - it is blown into the reflector 3 _ cooling airflow, must be secret (4) set the fan 5 in the action, can not achieve the purpose of different diversion, and blow the airflow from the outside The practice 'often causes the cooling airflow to flow only between the air gaps %, and the flow cannot be surely flowed, so the upper surface of the discharge region la' cannot achieve an effective cooling effect on the lamp discharge region h. The airflow entering the reflector will be cooled to the lower half of the discharge region la, in addition to cooling the upper half of the discharge region la. In terms of the temperature distribution of the discharge region ^, due to the thermal effect of the mercury vapor, most of the wire vapor is concentrated in the upper half of the discharge region 1 in 1261858, and the upper half of the discharge region & The cooling effect; on the contrary, the lower half of the Wei domain la = low temperature, the cooling of the money is not the operation of the high-volume body; However: while the cooling airflow is affected by the force and heat convection, it tends to form a strong cooling effect on the lower half of the discharge region la, so that the temperature in the lower half of the discharge region h is too low, and the airflow is condensed. Tungsten Weiqing axis blackening ability, while the upper half of the discharge area la is too high, forming a phenomenon of quartz glass damage. Therefore, in order to pass the cooling airflow through the intended cooling position, the internal structure of the reflector 3 and the discharge lamp tube 1 must be complicated in design and are not cost effective. Thirdly, the fan 5 is blown from the outside of the counter material 3, and the effect of actually passing the cooling airflow through the air gap 3a is not good. The cooling effect is concentrated on the outer surface of the reflector 3 or the ceramic seat 2, for the inside of the reflector 3 The cooling effect of the discharge region la and the reflective coating surface inside the reflector 3 is not good. In order to guide the cooling airflow through the intended cooling position to achieve the desired cooling effect, US Pat. No. 6,724,147 proposes a high-pressure gas discharge lamp with a gas guide assembly, which is attached to the neck of the reflector 3 and inserts a tubular air passage. The cooling airflow is directly blown toward the upper half of the discharge region A of the discharge lamp tube 1 to be cooled. However, this design creates two problems: 1. After the discharge lamp tube 1 is inserted into the neck of the reflector 3, the remaining body is actively small, so the tubular air passage must be made into a tube body having a small inner and outer diameter. The method is installed on the neck of the reflector 3, and is aligned with the discharge area ia of the discharge lamp 1. The air passage size is too small, the production cost is high, the installation is not easy, and it is easily damaged by external force. 1261858 The f-shaped two-gas passage directly guides the cooling airflow to cool the discharge area la, which lacks a better cooling effect on the anti-shooter 3. Especially in the discharge lamp! The hole opening 4, 彖, and the upper half of the discharge area h close to the discharge lamp tube ,, after receiving a large amount of heat of the heat of the Han, the temperature is much higher than other parts, forming thermal stress, easily damaged by thermal stress and stone τ The clothes are too concentrated to cool the discharge area la, so that the cooling amount of the reflector 3 is insufficient, and the system fan is added to solve the problem that the temperature inside the reflector 3 is too high, causing the surface of the reflective ore film to fall off. Therefore, the patent No. 24147 has not been solved. • The cooling problem of the discharge lamp 1 and the reflector 3 is solved. SUMMARY OF THE INVENTION In view of the above problems, the main object of the present invention is to provide a cooling device for a high-pressure gas discharge lamp, which is capable of cooling a discharge lamp tube and a reflector, and has a temperature distribution consistent with a high light-emitting rate and can be extended. The need for longevity. In order to achieve the above purpose, the present invention provides a cooling device for a high-view discharge lamp, which comprises a flow guiding element and an airflow generating device, which are mounted on the neck of the reflector cover. The discharge lamp of the reflector is cooled. In the basin, the reflection of the reflector is worn, the discharge lamp is worn through this hole, and the discharge area is located on the leakage surface of the reflector or the elliptical _ difficult point, and the discharge lamp is made of temperature resistant.

When the flow guiding element 40 is connected to the 13 I261858, two vent holes 43 are opened, corresponding to the two airflow generating devices 5. Each of the vent holes 43 is connected to the airflow generating device 5 by a duct 44, and the length of each of the ducts 44 is not more than 5 cm. The two airflow generating devices 50 can simultaneously blow or inhale. Taking "figure 5" as an example, the airflow generating device 50 simultaneously blows air toward the vent hole 43, so that the cooling airflow enters the through hole 13 and passes through the discharge lamp. The gap between the tube 30 and the neck cymbal 2 produces a cooling effect on the discharge area 31 and the reflector neck 12, and finally the hot air flow leaves the air gap π of the headlight cover glass 20 via the reflector 10. As shown in Fig. 6, the airflow generating device 50 simultaneously inhales the vent hole 43, and the cooling airflow passes through the air gap 11 of the reflector 10 and the headlight cover glass 20, and then faces the discharge region 31 and the reflector neck. 12 produces a cooling effect, and finally the hot gas flows through the gap between the discharge lamp tube 3 and the neck portion 12, and exits through the vent hole 43. The cooling airflow of the present invention flows through the reflector neck portion 12 and the discharge region 31, and can control the temperature of all of the reflector neck 12 and/or the discharge region 31, or cool the upper half of the reflector neck 12 and/or The upper half of the discharge area 31, or the cooling reflector • the lower half of the neck 12 and the lower half of the discharge area 31. After the discharge lamp tube 30 is extinguished, the airflow generating device 50 can continue to operate for a period of time, so that the quartz glass bulb of the discharge lamp tube can be accelerated to cool, so that the discharge fresh 3Q can be hot start or cold start. Restart quickly. The airflow generating device 50 can change the effect of the airflow (10) according to the change of the temperature of the discharge region 31, and control the temperature of the lamp casing to make the high-pressure gas discharge lamp work at the same time. life. Generally, the high-pressure gas discharge 4 is a surface, and its soft tilt is about, so its operation 14 1261858 must be less than this temperature point, and the surface temperature of the discharge area 31, because of the quartz glass The material limit must be lower than (4). c (the temperature inside the spherical shell passes through the lamp housing and the temperature difference), the discharge region 31 of the cooling material and the touchable electrode of the present invention performs effective cooling and temperature control, thereby ensuring that the discharge lamp is in contact with the electrode The high temperature T operation produces the best light release rate without exceeding the upper limit of the electrode and quartz glass material, prolonging the service life of the high pressure gas discharge lamp. In addition to effectively cooling the discharge tube, the cooling airflow flows directly through the gas flow channel through the counter-contact 12, and indeed passes through the edge of the hole U to effectively cool the reflector. The neck 12 and the hole 132 of the hole 132 can avoid the temperature from drastically changing to form thermal stress, and cause the reflector to be thermally shocked or broken due to thermal expansion and contraction. At the same time, the cold pure flow system flows through the gas (4), so that the cold milk can be found in the inner side of the fresh 1G, and the inner wall of the reflector (7) can be simultaneously cooled to prevent the reflective coating from deteriorating early. As described in the above, the present invention can control the area through which the cooling airflow flows to control the different areas of the discharge lamp tube and the anti-fresh 1 (4), and can be used for the neck of the reflector half (four) or the U half of the field, or the neck of the reflector. 12 lower half and / or discharge area door 1 lower half box .... For the control of the flow direction of the cooling air flow, the design of the flow element 40 and the application of the temperature-resistant cement or the coating of the paste 14 can be utilized to guide the flow direction of the cooling air flow. The core is designed to directly guide the flow guiding structure to the inside of the flow guiding element 4, and the cooling airflow is guided by the upper half and the lower half of the lightning light. . " 'Reading Figure 8', the illumination 1261858 of the third preferred embodiment of the present invention comprises a high-pressure gas discharge lamp set and a cooling device, wherein the structure of the high-pressure gas discharge 4 is substantially The first embodiment is the same as the preferred embodiment, and includes a reflection 10, a headlight cover glass 20, and a discharge lamp 30, and a cooling device is disposed on the reflective neck portion 12 to cool the discharge lamp tube 30 and the reflector 10. . The cooling device comprises a flow guiding element 60 and an air flow generating wire 5 (), in order to improve the guiding effect of the cooling air flow, in Lin Shicai, the vent 63 is located on the upper side of the flow guiding element (four), and the discharge, the tube 30 is completely resistant The warm concrete or the f 14 is fixed to the tooth hole 13 of the reflector neck η, and the air passage is formed between the discharge lamp tube 3〇 and the reflector cover 12, and the temperature is resistant to cement or ceramic paste. The 14th line fills the lower half of the through hole 13, so that the air passage generating device 5() is formed by the early flow of the flow guiding element (9) and the air or air blow, except for In addition to the circulation of the cooling airflow, it is also possible to control the cold parts. For example, the airflow generating device 5 is configured to blow the vent hole 63. After the airflow passes through the vent hole 63, the air passes through the hole wall of the hole 13 and the discharge lamp tube 3〇, and is Flowing through the upper half of the airflow path (because the lower half is already filled with /JBL ceramic cement or ceramic paste 14), the cooling effect is concentrated on the upper half of the reflector neck 12 and the discharge area 3丨, after the heat absorption The hot air exits through the air gap 11 on the upper side of the reflector 10. In addition, the lower half of the airflow path is filled with the ceramic paste 14, and the upper guide hole is formed to allow the cooling airflow to pass through the vent 63. Flowing directly toward the upper half of the venting channel does not wrap around the interior of the guiding element 60, reducing the resistance of the cooling airflow as it flows inside the yoke element 60, and avoiding the cooling airflow being 'concentrated cooling effect. The catheter of the first embodiment may be selectively provided in the present embodiment to remove the catheter design to simplify the outer junction 16 261 858 of the flow guiding element 60. The outer side of the flow guiding element 60 is >咖τ ^ ” ϋ卩 ϋ卩 ϋ卩 no prominent catheter design, The airflow generating device is Μ) and the opposite person is blown or inhaled by the Converse 63. In order to maintain the airflow with a % of the airflow, the distance between the airflow generating “6() and the venting illusion is not more than ^cm, In order to reduce the efficiency of the flow of the cooling airflow, the airflow generating device 50 of the third preferred embodiment can be blown in addition to the air vent 63. , g # 1 ο 扎 h inhaled, so that the cooling airflow enters from the air gap U, and is removed by the reduction 63.
