Description of the Invention: [Technical Field] [0001] The present invention relates to a lens module and a camera module having the lens module. [Prior Art] [0002] A lens module generally includes a plurality of lenses for a spacer for spacing two adjacent lenses and a light blocking mechanism for eliminating stray light in the lens module. However, in the trend of miniaturization of the lens module, the additional light blocking mechanism increases the volume of the lens module, which is disadvantageous for miniaturization and simplification of the lens module. 〇 [Summary of the Invention] [0003] In view of the above, it is necessary to provide a lens module and a camera module that are advantageous for miniaturization and simplification of the structure. [_4] A lens module comprising a first lens' spacer and a second lens arranged in this order from the image side of the lens module. The second lens includes a first optical portion and a first supporting portion, the first supporting portion is disposed around the first optical portion, and the first supporting portion includes a first lens portion on the first lens image side and facing the first lens Side recessed face. The spacer includes a matte portion extending along the concave surface and covering the concave surface of the disk. [_-Type reduction module] The above lens mode reduction sensor.

Referring to FIG. 1 , a lens module 100 according to a first embodiment of the present invention includes a first lens 21 , a second lens 22 , a third lens 23 , a fourth lens 24 , and a first spacer 31 'second spacer 32 . The third spacer 33' is a fourth spacer 34, a glass piece 40 and a lens barrel 50. a third lens 23, a first spacer 31, a fourth lens 24, a second spacer 32, a first lens 21', a third spacer 33, a second lens 22, a fourth spacer 34, and a glass sheet 40 from the lens The module 1 is arranged in order from the object side to the image side and is housed in the lens barrel 50. The lens barrel 50 has a light-passing hole 51 at an end close to the object side of the lens module 1 . Light can be incident on the third lens 23 through the light passing hole 51. The third lens 23 is a lenticular lens, and the fourth lens 24 is a convex lens that protrudes toward the object side of the lens module 1. The first lens 21 is a convex lens that protrudes toward the image side of the lens module 100, and the second lens 22 is a convex lens. The lens module 100 is a convex lens that protrudes from the side. The four lenses 21, 22, 23, 24 can be made of plastic or glass or one or more of them are plastic, and the rest is glass, which can be selected according to actual needs. Further, the first lens 21 includes a first optical portion 212 and a first support portion 214. The first support portion 214 is disposed around the first optical portion 212. The first support portion 214 includes an image of the first lens 21 A concave surface 216 that is recessed toward the object side of the first lens 21 side. The first optical portion 212 is an optical portion that protrudes toward the image side of the lens module 100. The second lens 22 includes a second optical portion 222 and a second support portion 224, and the second support portion 224 is disposed around the second optical portion 222. 099111660 Form No. A0101 Page 4 / Total 11 Page 0992020634-0 [0012] 201135302 [0013] 〇 [0015] The first piece 31, the second spacer 32 and the fourth spacer 34 are substantially flat The second spacer 33 includes a μ spacer 332 and a matting portion 334. The door partition 4332 is substantially flat, and the partition portion (10) is located between the first branch sill 214 and the first support portion 224 and is in contact with the first bridging portion and the beta first support portion 224. The matting portion extends along the concave surface 216 from the spacer (10) and covers the concave surface 216. Preferably, the matting portion has a shape matching the shape of the concave surface 216 to better conform to the concave surface 216. «The spacer 3 32, 33 is made of a copper sheet coated with black paint on the surface, or Black P〇iyester. In the case of the former material, the copper sheet may be first punched out of the (10) impurity, and then the black paint may be applied; if it is the latter material, the shape required for the hot pressing of the black polyester may be obtained. Of course, in other embodiments, other materials suitable for the spacer may be selected, such as other materials having light absorbing and light blocking functions. Since the matting portion 334 extends along the concave surface 216 and covers the concave surface 216, 1) the matting portion 334 can effectively block the stray light emitted from the first lens 21 to the second lens 22 via the concave surface 216; 2) the matting portion 334 It is also effective to absorb stray light that is emitted from the outside of the first lens 21 toward the concave surface 216; and 3) the matting portion 334 does not block the image light that is emitted through the first optical portion 212 to the second lens 2 2 . The glass piece 40 closes the end of the lens barrel 5 near the image side of the lens module 1 to prevent dust and moisture from entering the image sensor via the lens barrel 50 (see Fig. 2). The lens module 100' facilitates miniaturization and simplification of the lens module by providing an additional element that does not need to be added by the third spacer 33' having the matting portion 334. At the same time, the third spacer 33 is more completely shielded from light. 099111660 Form No. A0101 Page 5 of 11 0992020634-0 [0016] Referring to FIG. 2, a camera module 200 according to a second embodiment of the present invention includes the lens module 100 and the image sensor. 300. The image sensor 300 is disposed on the image side of the lens module 100 and receives light from the lens module 100 for imaging. Therefore, the use of the third spacer 33 facilitates miniaturization and simplification of the camera module 200. At the same time, since the third spacer 33 can effectively eliminate stray light, the image quality of the image sensor 300 is improved. [0018] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law.
