The effects and technical features of the present invention, as well as the technical means of the present invention, will be described in detail below with reference to the accompanying drawings. It is noted that the inventive concept may be embodied in a variety of different forms and should not be construed as being limited to the illustrated embodiments. Accordingly, the present embodiments are provided by way of example and are in the In the drawings, the embodiments of the present invention are not limited to the specific examples provided below, and in addition, in order to make the disclosure clear, the description will be used.

As shown in FIG. 1, according to an exemplary embodiment of the present invention, a lens assembly 10 suitable for use in an accessory includes a housing 20 having a hollow hole formed therein, a film 30 on the lower surface of the housing 20, and an image formed thereon. Below the film 30, the transparent support member 40 supporting the film 30 from the lower portion of the outer casing 20, the convex lens 50 at the upper portion of the outer casing 20 and having a low magnification, and the outer casing 20 are separated from the film 30 and the convex lens 50. The convex lens 60 has a high magnification.

Therefore, the photo or picture placed in the accessory can be enlarged to a maximum value by the lens group 10 suitable for the accessory.

The upper portion of the outer casing 20 is wider than the lower portion of the outer casing 20 such that the range of the convex lens 50 is larger than the range of the lower convex lens 60.

Therefore, since the range of the convex lens 50 is larger than the range of the lower convex lens 60, the magnification of the lens can be increased so that the image size formed on the film 30 looks larger than the size of the actual image.

Different images, such as photographs or pictures, can be formed on film 30, and film 30 can be about 0.1 millimeters (mm) thick.

The transparent support member 40 is formed of a transparent material or a semi-transparent material and adheres to the lower surface of the film 30 such that the reflected light reflected by the mirror 70 (which will be described later) is transparent to the transparent support member 40.

Although a specific embodiment of the present invention has been described in which the transparent support member 40 is formed of a transparent material or a semi-transparent material to allow light to pass through, the present invention is not limited thereto. In accordance with another exemplary embodiment of the present invention, the transparent support member 40 can be formed from a phosphorescent material, such as a phosphorescent pigment that can absorb, store, emit, and emit light. When the transparent support member 40 is formed of a phosphorescent pigment, the phosphorescent pigment can be plated on the lower surface of the film 30.

As shown in FIG. 1, the lower convex lens 60 is positioned inside the outer casing 20 such that the focal length conversion ratio between the lower convex lens 60 and the upper convex lens 50 is set to 2:1.

For example, if a focal length is from the upper surface of the upper convex lens 50 to the upper surface of the film 30, that is, where the image is formed, it is represented by the symbol D, and the maximum thickness of the convex lens 50 and the lower convex lens 60 is represented by the symbol H. It is shown that the distance between the lower surface of the upper convex lens 50 and the upper surface of the lower convex lens 60 is represented by the symbol d, then d is equal to D/2-H, and the lower surface of the lower convex lens 60 and the upper surface of the film 30 are The distance between them is equal to d/2.

As an exemplary embodiment of the present invention, when the upper convex lens 50 and the lower convex lens 60rm have a curvature of 3.4R, the H system is 1.74 millimeters (mm), and the focal length D is 6.8 millimeters (mm), the convex lens is used. The distance d between the lower surface 50 and the upper surface of the lower convex lens 60 is 1.66 millimeters (mm), and the distance between the lower surface of the convex lens 60 and the upper surface of the film 30, that is, d/2 is 0.83 mm ( Mm).

Therefore, in the case of a high-magnification microscope (magnification of 60 or more), the magnification of the lens can be increased to such an extent that the image size formed on the film 30 is much larger than the actual image size.

The position of the upper convex lens 50 and the lower convex lens 60, and the distance between the lower surface of the upper convex lens 50 and the upper surface of the lower convex lens 60 can be adjusted according to the magnification of the lens used.

In accordance with the present invention, in order for the lens assembly 10 to be applied to an accessory, such as a ring 1 or a necklace, the outer casing 20 is provided within the ring 1 or necklace.

In accordance with an exemplary embodiment of the present invention, as shown in FIG. 2, the outer casing 20 is provided within the ring 1 or necklace such that the lens set 10 suitable for the fitting is adaptable to the ring 1. For those of ordinary skill in the art to which the invention pertains, a lens set 10 suitable for use in an accessory according to the present invention is applicable to Accessories such as key rings or mobile phone charms, or decorative items such as bottles or vases.

The outer casing 20 further includes a support member 21, and preferably the support member 21 has a distance between the outer casing 20 and the fitting in which the outer casing 20 is placed, such as a ring.

As shown in FIG. 2, if the lens group 10 suitable for the accessory is applied to the ring 1, it is preferable that the lens group 10 suitable for the accessory further includes the mirror 70 located below the transparent support member 40.
