Description of the Invention: [Technical Field] The present invention relates to a lens module, and more particularly to a lens module having infrared imaging and visible light imaging. [Prior Art] With the development of camera technology, camera modules are widely used in various types of camera devices. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc., has been widely received by many consumers. Favor. The lens is an essential component of the camera module, and the function of the lens directly determines the function of the camera. Depending on the application, the lens has a standard lens, a wide-angle lens, a special lens, and so on. In general, a lens module has only one function, and therefore, a camera using the lens module generally has only one function. If you want to get different images from the camera, for example, you need to get an infrared image of the object, you need to replace the lens of the camera with a lens with infrared camera function or a camera with infrared camera function. This increases the cost of the camera for interchangeable lenses; in addition, because the camera is compatible with different lenses, different lenses tend to have different structures, which makes the camera more complex. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a lens module having infrared imaging and visible light imaging. A lens module includes a lens barrel, a lens holder, a filter holder, and a filter switch piece. An optical element is disposed in the lens barrel and the lens barrel is housed in the lens holder. The filter 5 200827902: an infrared ray cut filter and a slab are disposed on the switch sheet, the filter holder is located on the lens barrel, and the mirror switch piece can be slid on the sley to enable the infrared cut filter and the The optical elements in the barrel correspond to each other. (9) The technology of the pass and the moon, the lens module corresponding to the optical component in the lens barrel by sliding on the filter holder, so that the camera with == does not need to be replaced. The lens module has two functions: line imaging and visible light imaging. [Embodiment]: The surface will be described in detail in conjunction with the present invention. Referring to FIG. 1 and FIG. 2, the present invention provides a mirror-mounted group i 10 having two functions of infrared "seeing light camera", including a lens barrel u, a lens holder 12, The lens mount 红外 infrared 荔 m filter filter switch 14, 14, cut filter 15 and visible cut filter 16. The lens cartridge U is housed in the lens mount 12 and can be mounted on the lens mount 12 internal rotation. In the same brother 11, there are a number of optical elements 袢 ^ one (not shown) so that the lens barrel 11 has a second end such as a telephoto, a focus, etc. The lens barrel 11 is away from the lens mount 12 lens The groove 11G, the groove 11G is coaxial with the lens barrel 11. The bearing cylinder u, (4) is shown in the figure: module: has =: seat 12嶋^, == tube structure 'one end can be just accommodated in the groove m ^Two symmetrical protrusions are formed in the direction of the reading barrel η. The free end of the protrusion 130 is bent inwardly to form a bent portion 132. The middle portion of the inner surface of the protrusion 13 is provided with a bump 13 〇 2 for filtering, The lens holder 13 is stably received in the recess 110, and the filter and the lens holder 13 can be abutted in the recess 110 by means of bonding (for example, dispensing). The switching piece 14 has a rectangular parallelepiped shape having a width slightly smaller than the distance between the two dog-like members 130 and a thickness slightly smaller than the height of the protrusion 13'' to allow the filter switching piece 14 to move in the region between the protrusions 13A. The folding portion 132 is used for holding and restricting the moving direction of the frog mirror switching piece 14, so as to move in the area surrounded by the dog 130 without leaving the filter holder a. The ft mirror switching sheet 14 has two The side 141, the first accommodating area 142, the second accommodating area 144, the switching manipulation portion 146 and the four recesses 148 are disposed opposite to the protrusion 13(). The first accommodating area 142 is a hollow square. The infrared occlusion filter 15 is disposed at least at one corner of the first accommodating area 142. Optionally, the first accommodating area 142 can also be rectangular, circular, etc. The second accommodating area 144 is a hollow square for accommodating the visible cut filter 16. At least one corner of the second receiving area 144 has a second dispensing location 1442, passing through the second dispensing location 1442 The glue fixes the visible cut filter 16 in the second accommodating area 144. Alternatively, the second accommodating area 144 may also be rectangular, circular, etc. The switching control unit 146 has the same along the filter switching piece 14. One end of the two accommodating area 144 is extended, and three ribs 1462 are disposed thereon. Of course, the ribs 7 200827902 1462 may also be one, two or more. When the hand is held by the switching control unit 146, it occurs. When displaced, the filter switching piece 14 is movable between the projections 130. The rib I462 can increase the friction between the hand and the switching manipulation portion 146. Of course, the switching manipulation portion 146 may also be provided at the other end of the filter switching sheet 14.
# \ 四個凹槽148分兩組分別位於與突起13〇相接觸的兩 個側邊141上。凹槽148分別位於第一容置區142及第二 容置區144所對應侧邊141部分的中間位置。 可選擇地是，濾鏡切換片14上設置有三個凹槽148， 一條側邊141上設置兩個，另一側邊141上設置一個；或 者設置兩個凹槽148，其分別設置在兩個側邊14]L上，一 個凹槽位於第一容置區142所對應侧邊141部分的中間位 置，及另一個凹槽148位於第二容置區ι44所對應側邊ι41 部分的中間位置。 當濾鏡切換片14移動至凸塊13〇2伸入凹槽148中， 可實現濾鏡切換片14的定位功能，以使在進行拍攝時濾鏡 切換片14無法發生移動，保證拍攝的效果。 鏡頭模組10通過設置具有紅外線截止濾光片15和可 見光截止濾光片16的濾鏡切換片14,使紅外線截止濾光 片15或者可見光截止濾光片16之一與鏡筒“内的光學元 :相對應以實現不_攝像功能。當紅外線截止濾、光片15 έ ^至鏡同11上方時，由於紅外線截止濾、光片15允許除 :軏？之外的光線進入鏡筒11，因此，鏡頭模組10可在 1環境或可見光下攝像。當可見光截止濾 1片16移動至 200827902 鏡筒11上方時，由於可見光截止濾光片15允許除可見光 之外的光線進入鏡筒11，因此，鏡頭模組10可在紅外線 環境或者夜晚攝像。 綜上所述，本發明符合發明專利要件，爰依法提出專 利申請。惟，以上所述者僅為本發明之較佳實施方式，本 發明之範圍並不以上述實施方式為限，舉凡熟習本案技藝 之人士援依本發明之精神所作之等效修飾或變化，皆應涵 蓋於以下申請專利範圍内。 【圖式簡單說明】 圖1係本發明實施例鏡頭模組之立體示意圖。 圖2係圖1的鏡頭模組之主體分解示意圖。 圖3係圖1的鏡頭模組中濾鏡切換片之立體示意圖。 【主要元件符號說明】 鏡頭模組 10 鏡同 11 鏡頭座 12 爐、鏡座 13 濾鏡切換片 14 紅外線截止濾光片 15 可見光截止濾光片 16 環形凹槽 110 突起 130 彎折部 132 凸塊 1302 侧邊 141 第一容置區 142 第二容置區 144 切換操控部 146 凹槽 148 第一點膠處 1422 第二點膠處 1442 凸肋 1462# \ Four grooves 148 are divided into two groups on the two side edges 141 which are in contact with the protrusions 13A. The grooves 148 are respectively located at intermediate positions of the first accommodating portion 142 and the corresponding side 141 of the second accommodating portion 144. Alternatively, the filter switching sheet 14 is provided with three recesses 148, one on one side 141, one on the other side 141, or two recesses 148, which are respectively disposed in two On the side 14] L, one groove is located at a middle position of the portion of the corresponding side 141 of the first accommodating area 142, and the other groove 148 is located at an intermediate position of the side ι41 portion corresponding to the second accommodating area ι44. When the filter switching piece 14 is moved to the protrusion 13〇2 and protrudes into the groove 148, the positioning function of the filter switching piece 14 can be realized, so that the filter switching piece 14 cannot be moved during shooting, and the shooting effect is ensured. . The lens module 10 is provided with the filter switching sheet 14 having the infrared cut filter 15 and the visible cut filter 16, so that one of the infrared cut filter 15 or the visible cut filter 16 and the optical inside the lens barrel Element: Corresponding to achieve the non-camera function. When the infrared cut filter, the light sheet 15 έ ^ to the top of the mirror 11 , due to the infrared cut filter, the light sheet 15 allows light other than: 軏 to enter the lens barrel 11, Therefore, the lens module 10 can image in 1 environment or in visible light. When the visible cut filter 1 is moved over the 200827902 lens barrel 11, since the visible light cut filter 15 allows light other than visible light to enter the lens barrel 11, Therefore, the lens module 10 can be imaged in an infrared environment or at night.
