-般車輛所用的車頭燈，主要是採用具有雙燈絲之 函素燈泡’或者使用兩個燈泡來作為遠光燈及近光燈之 切換。雙燈絲之燈泡無法達成高亮度及低耗電之效果， 而使用兩個燈泡的作法必須多使用-組燈罩，使得成本 無法有效降低。函素燈呈黃色，色溫值約2〇〇〇至， 亮度不高，使用壽命短（約400小時），且鹵素燈的功率 較大，約為55瓦，且工作電流高達約5·5安培。 目刚市面上已經有高壓氣體放電車燈。高壓氣體放 電車燈的優點如下。高壓氣體放電燈發出的白光之色溫 值約為5000至8000κ。因此，高壓氣體放電車燈之輸出 亮度值約為鹵素燈的三倍，對於提升駕駛夜間視線清晰 度有明顯的效果。此外，高壓氣體放電車燈所發出的光 線接近由白色略微轉藍色的色溫，也最接近正午日光的 顏色，使得人眼的接受度及舒適度更高。再者，高壓氣 體放電車燈之使用壽命長，約可達25〇〇小時。由於古^ 氣體放電車燈係利用電流刺激氣體發光，所以基本上= 會產生高溫。一組高壓氣體放電車燈在正常的使用條件 下，至少有六年的使用壽命。此外，高壓氣體放電車燈 5 200817629 的功率（約35W)遠低於鹵素燈的功率（約55W)。然而，這 些高壓氣體放電車燈無法切換其焦距。 【發明内容】 因此，本發明之一個目的係提供一種可切換焦距之 高壓氣體放電燈組件，為目前高壓氣體放電燈提供一種 可切換高壓氣體放電燈焦距之結構。 為達上述目的’本發明提供一種可切換焦距之高壓 氣體放電燈組件，其包含一殼體、一高壓氣體放電燈模 組及一移動機構。殼體中形成有一容置空間。高壓氣體 放電燈模組係設置於容置空間中並具有一高壓氣體放電 燈。咼壓氣體放電燈之一軸向為一第一方向且高壓氣體 放電燈用以發出一光線。移動機構設於容置空間中，並 與高壓氣體放電燈模組接觸，用以將高壓氣體放電燈模 、、且朝第一方向驅動，第一方向與第二方向之夾角實質 上介於100至17〇度之間。 ^為讓本發明之上述目的、特徵、和優點能更明顯易 K下文特舉一車交4圭實施例，並配合所附圖式，作詳細 呑兄明如下。 【實施方式] 圖j與2分別顯示依據本發明較佳實施例之可切換 :距之^壓乳體放電燈組件之第一與第二狀態。如圖1 2所不，本實施例之一種可切換焦距之高壓氣體放電 燈組件1包含一 Μ挪，Λ ^ 几又體1 0、一尚壓氣體放電燈模組20、_ 6 200817629 幾構30及一後蓋40。殼體10中形成有一容置空間 U回壓氣體玫電燈模組20係設置於容置空間^中並 ’、有巧壓氣體放電燈21。高壓氣體放電燈21之一龢 ° ”、、一弟一方向D1且高壓氣體放電燈21用以發出一光 L产^動機構3〇設於容置空間11中，並與高壓氣體放 電垃杈組20接觸，用以將高壓氣體放電燈模組2〇朝一 r 第二方向D2驅動。第一方向D1與第二方向D2之夾角 、；|於1⑼至170度之間，最好是介於12〇至15〇 :之間，更佳是等於129度。夾角A係與傳統的雙燈絲 :素燈的向量相當，因此，可以沿用舊有車燈的聚光曲 面。 U叫 :動機構30包含一導向滑桿31，其沿著第二方向⑴ =问壓氣體放電燈模組20並插設於殼體10上，以導 雨壓氣體放電燈模組20沿著第二方向D2滑動。 電磁構Μ包含—電磁鐵32及—電磁鐵運動桿33。 者，移動機構'電::載3 2驅動而朝第二方向D 2移動。或 成。動機構30亦可以利用馬達配合其他傳動機構而達 電磁鐵運動桿33係可被電磁鐵 個位置，於本實施例中係為兩個位置/\ 動而^於多 的是，亦可依據需“定_置的數目\P2。值得注意 戟運動# 33被電磁鐵32驅動 田電 #，會帶動高I氣體放電燈模組 ：=D2移動 動，達到切換焦距的效果。 ^向滑捍h上滑 7 200817629 後蓋40係與殼體1 〇接觸，用以包圍容置空間1 i。 藉由本發明之上述構造，殼體1〇本身具有呈夾角A 之相鄰兩段，因此使用者可以方便地握住殼體1 〇來進行 安裝，達到安裝便利化的效果。此外，由於夾角A係與 傳統的雙燈絲的向量相當，因此可以沿用舊有車燈的聚 光曲面，故使用者只需要更換本發明之裝置即可達成將 鬲壓氣體放電燈所發出的光線進行變焦的效果。 在較佳實施例之詳細說 用以方便說明本發明之技術 限制於上述實施例，在不超 專利範圍之情況，所做之種 之範圍。 明中所提出之具體實施例僅 内容，而非將本發明狹義地 出本發明之精神及以下申請 種變化實施，皆屬於本發明 200817629 【圖式簡單說明】 圖"員示依據本發明較佳實施例之可切換隹 壓氣體放電燈組件之第一狀熊。 “、、 圖" 員示依據本發明較佳實施例之可切 迻氣體放電燈組件之第二狀態。 、’、、、 门 【主要元件符號說明】For the headlights used in general vehicles, it is mainly to use a light bulb with a double filament or to use two bulbs as a switch between the high beam and the low beam. A double-filament bulb cannot achieve high brightness and low power consumption, and the use of two bulbs must use a multi-group lampshade, so that the cost cannot be effectively reduced. The light element is yellow, the color temperature is about 2 〇〇〇, the brightness is not high, the service life is short (about 400 hours), and the power of the halogen lamp is large, about 55 watts, and the working current is as high as about 6.5 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 white light emitted by a high pressure gas discharge lamp is about 5,000 to 8,000 κ. Therefore, the output value of the high-pressure gas discharge lamp is about three times that of the halogen lamp, which has a significant effect on improving the visibility of the night vision. In addition, the light emitted by the high-pressure gas discharge lamp is close to the color temperature which is slightly turned blue by white, and is also closest to the color of noon daylight, which makes the acceptance and comfort of the human eye higher. Furthermore, high-pressure gas discharge lamps have a long service life of up to about 25 hours. Since the ancient gas discharge lamp system uses current to stimulate the gas to emit light, basically = high temperature is generated. A group of high-pressure gas discharge lamps have a service life of at least six years under normal conditions of use. In addition, the power of the high-pressure gas discharge lamp 5 200817629 (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, and 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 present invention provides a switchable focal length high pressure gas discharge lamp assembly comprising a housing, a high pressure gas discharge lamp module and a moving mechanism. An accommodating space is formed in the housing. The high-pressure gas discharge lamp module is disposed in the accommodating space and has a high-pressure gas discharge lamp. One of the rolling gas discharge lamps is axially oriented in a first direction and a high pressure gas discharge lamp is used to emit a light. The moving mechanism is disposed in the accommodating space and is in contact with the high-pressure gas discharge lamp module for discharging the high-pressure gas discharge lamp and driving in the first direction, wherein the angle between the first direction and the second direction is substantially 100 Between 17 degrees. In order to make the above objects, features, and advantages of the present invention more apparent, the following is a detailed description of the present invention, and in conjunction with the drawings, the details are as follows. [Embodiment] Figures j and 2 respectively show the first and second states of the switchable discharge lamp assembly according to a preferred embodiment of the present invention. As shown in FIG. 12, a switchable focal length high-pressure gas discharge lamp assembly 1 of the present embodiment includes a Λ^, a few body 10, a still-pressure gas discharge lamp module 20, _ 6 200817629 30 and a rear cover 40. An accommodating space is formed in the casing 10. The U-return gas illuminating lamp module 20 is disposed in the accommodating space and is provided with a gas discharge lamp 21. One of the high-pressure gas discharge lamps 21 and the "one" direction D1 and the high-pressure gas discharge lamp 21 are used to emit a light-emitting mechanism 3 disposed in the accommodating space 11 and discharged with the high-pressure gas. The group 20 is in contact for driving the high pressure gas discharge lamp module 2 to the second direction D2. The angle between the first direction D1 and the second direction D2 is between 1 (9) and 170 degrees, preferably between 12〇 to 15〇: Between, it is better to be 129 degrees. The angle A is equivalent to the traditional double filament: the vector of the plain lamp, so the concentrated surface of the old lamp can be used. U: Motion mechanism 30 A guiding slider 31 is disposed along the second direction (1) = the gas discharge lamp module 20 is inserted into the casing 10 to slide the rain-pressing gas discharge lamp module 20 along the second direction D2. The electromagnetic structure includes an electromagnet 32 and an electromagnet movement rod 33. The moving mechanism 'Electrical:: is driven by the 3 2 drive and moved in the second direction D 2 . Alternatively, the moving mechanism 30 can also utilize a motor to cooperate with other transmissions. The electromagnet moving rod 33 of the mechanism can be positioned by the electromagnet, which is two positions in this embodiment. ^More than that, you can also "set the number of \P2. It is worth noting that 戟## is driven by electromagnet 32. Tiandian #, will drive the high I gas discharge lamp module: =D2 moves to achieve the effect of switching the focal length. ^Slide to the slider h 7 200817629 The rear cover 40 is in contact with the housing 1 , to surround the accommodating space 1 i. According to the above configuration of the present invention, the casing 1 itself has two adjacent sections at an angle A, so that the user can conveniently hold the casing 1 to perform mounting, thereby facilitating the installation. In addition, since the angle A is equivalent to the traditional double filament vector, the concentrated curved surface of the old lamp can be used, so that the user only needs to replace the device of the invention to achieve the light emitted by the pressure gas discharge lamp. The effect of zooming.
