Field of the Invention The present invention relates to a high-pressure gas discharge lamp assembly that can switch focal lengths, particularly to a high-pressure gas discharge lamp assembly that uses an electromagnet to zoom a high-pressure gas discharge lamp. [Prior Art] The headlights used in general vehicles use either a lenticular bulb with a double filament or two bulbs for switching between a high beam and a low beam. The double-filament bulb cannot achieve high brightness and low power consumption, and the use of two bulbs must use the _ group of lampshades, so that the cost cannot be effectively reduced. The halogen lamp is yellow, the color temperature value is about 2000 to 3000K, the degree of freedom is not high, and the service life is short (about 4 hours), and the halogen lamp has a large power of about 55 watts and an operating current of about 5.5 amps. ~ There are already high-pressure gas discharge lights on the market. The advantages of high pressure gas discharge lamps are as follows. The color temperature of the white light emitted by the high-pressure gas discharge lamp is about 500... Therefore, the output of the high-pressure gas discharge lamp has a value of about three times that of the i-lamp, which has a clear effect on improving the night vision of driving. In addition, the black 厥 厥 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 Furthermore, the high-pressure gas lamp has a long service life of about 2 hours. Due to the high pressure: the body discharge lamp system uses current to stimulate the gas to emit light, so basically does not produce two temperatures. - Group of high-pressure gas discharge lights in normal use conditions Up to eight years of use of life. In addition, the power of the high-pressure gas discharge lamp 1302589 (about 35W) is much lower than the power of the halogen lamp (about 55w). However, these high-pressure gas discharge lamps cannot switch their focal lengths. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a high-pressure gas discharge lamp assembly that can switch focal lengths to provide a high-pressure gas discharge lamp with a structure that can switch the focal length of a high-pressure gas discharge lamp. To achieve the above object, the gas discharge lamp assembly of the present invention comprises a set and a moving mechanism. The housing-shaped discharge lamp module is arranged to accommodate the empty lamp. One of the high-pressure gas discharge lamps is used to emit a light. The contact with the high pressure gas discharge lamp module is driven in a second direction, the first being between 10 〇 and 170 degrees. In order to achieve the above object of the present invention, a preferred embodiment is described below. A high-pressure housing capable of switching the focal length and a high-pressure gas discharge lamp are provided to form an accommodation space. The high-pressure gas has a high-pressure gas discharge direction in a first direction and the high-pressure gas moving mechanism is disposed in the accommodating space, and is used to discharge the high-pressure gas discharge lamp mode direction and the second direction. The advantages and advantages can be more obvious and detailed with the drawings. [Embodiment] The second and second states of the switchable 盥_礼 discharge lamp assembly according to the preferred embodiment of the present invention are shown. As shown in FIG. 2 and 2, in this embodiment, a high-pressure gas discharge capable of switching focal lengths, and M 1 includes a casing 10, a high-pressure gas discharge lamp module 20, a 1302589 moving mechanism 30, and a back cover. 40. An accommodating empty door is formed in the casing 10. The high-pressure gas discharge lamp module 20 is disposed in the accommodating space 丨丨 T and has a high-pressure gas discharge lamp 21. The i-direction of the high-pressure gas discharge lamp 21 is a first direction D1 and the high-pressure gas discharge lamp 21 is used to emit light. The moving mechanism 30 is disposed in the accommodating space 11 and is in contact with the high-pressure gas discharge lamp module 20 for driving the high-pressure gas discharge lamp module 2 to the second direction D2. The first direction D1 and the second direction D2 A are substantially between 100 and 17 degrees, preferably between 12 、 and 1 〇, and more preferably 129 degrees. The angle A is equivalent to the vector of a conventional double filament halogen lamp, so the concentrating surface of the old lamp can be used. The moving mechanism 30 includes a guiding slide rod 3 1 , which passes through the high-pressure gas discharge lamp module 20 along the second direction and is inserted into the casing 1 , and the pressure-discharged gas discharge lamp module 2 The second direction D2 slides. The moving mechanism 30 includes an electromagnet 32 and an electromagnet moving rod μ. The motor lever 33 abuts against the housing 1G and is connected to the high pressure gas discharge lamp module and is driven by the electromagnet 32 to move in the second direction 〇2. Or into. The moving mechanism 30 can also be positioned in a plurality of positions by a motor and other transmission mechanisms, and can be driven by the electromagnet 32 to be positioned at a plurality of positions in the present embodiment. According to the demand, the second magnet movement of the positioning position can be increased by 0. When the electric iron movement is driven by the electromagnet 32, the old-fashioned and touched a younger one can move D2 to move the body. The discharge lamp module 2 () moves to achieve the effect of switching the focal length. In the forward direction, "dry slide 7 l3 〇 2589 rear cover 40 is in contact with the housing 1 , to surround the accommodating space 11. With the above configuration of the present invention, the housing 10 itself has two adjacent segments at an angle A Therefore, the user can conveniently hold the housing 1 进行 for installation 'to achieve the convenience of installation. In addition, since the angle A is equivalent to the vector of the conventional double filament, the concentrated surface of the old lamp can be used. Therefore, the user only needs to replace the device of the present invention to achieve the effect of zooming the light emitted by the south-pressure gas discharge lamp. The specific embodiments set forth in the detailed description of the preferred embodiments are only for convenience of explanation. The technical content of the invention is not limited to the above-described embodiments, and various changes are made without departing from the spirit of the invention and the scope of the following: the scope of the invention: 1302589 BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a first array of preferred gas discharge lamp assemblies in accordance with the present invention.
