DETAILED DESCRIPTION OF THE INVENTION

The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

Referring to FIGS. 2 and 3, a sight structure in accordance with an embodiment of the invention includes a main body 150, an objective set 160, an eyepiece set 170, a seat 130, a lens 100 and a power supply module 190. In this embodiment, the main body 150 is substantially cylindrical. The objective set 160 and the eyepiece set 170 are respectively connected to two opposite ends of the main body 150. The seat 130 is disposed within the main body 150. FIG. 3 depicts the portion A of FIG. 2. The lens 100 is mounted to the seat 130. The power supply module 190 is disposed on an outer surface of the eyepiece set 170. As shown in FIG. 4, the power supply module 190 includes a power source 300 and a control circuit board 310. In operation, a light from an object (not shown) enters the main body 150 through the objective set 160, and sequentially passes through the lens 100 and eyepiece set 170 to be observed by the user.

In another embodiment, a sight structure further includes an inner cylinder 180. As shown in FIGS. 5 and 6, the inner cylinder 180 is disposed within the main body 150. The seat 130 is disposed in the inner cylinder 180.

Referring to FIGS. 7 and 8, the sight structure further includes electrodes 120 and 140 and a first light emitting member 200. The lens 100 further includes a surface 110. The electrodes 120 and 140 are formed on the surface 110. The electrode 120 is connected to an anode of the power source 300 through the control circuit board 310, and the electrode 140 is connected to a cathode of the power source 300 through the control circuit board 310. The electrodes 120 and 140 form a first aiming pattern. In this embodiment, the first aiming pattern is a reticle. The first light emitting member 200 is disposed at a center of the reticle. The electrodes 120 and 140 are disposed on two opposite sides of the first light emitting member 200 and connected to the first light emitting member 200 respectively. The electrode 120 constitutes a set of two adjacent arms of the reticle, and the electrode 140 constitutes another set of two adjacent arms of the reticle. Thus, the first light emitting member 200 emits light when current flows to the first light emitting member 200 through the electrodes 120 and 140. Specifically, the first light emitting member 200 emits light at the time or after the time that current flows to the first light emitting member 200 through the electrodes 120 and 140. In practical operation, the light emitted by the first light emitting member 200 enhances the clarity of the first aiming pattern, and a light including an image of the first aiming pattern enters the eyepiece set 170 to be observed by the user.

In one embodiment, electrical conductive material is coated on the surface 110 to form the electrodes 120 and 140 so as to form the first aiming pattern. In another embodiment, a groove is formed on the surface 110 by etching, and the groove has a shape corresponding to the first aiming pattern. Afterwards, electrical conductive material is filled into the groove to form the electrodes 120 and 140.

In this embodiment, the first light emitting member 200 emits white light. However, the invention is not limited thereto. On the contrary, different light emitting member emitting different color light can be used according to requirements. For example, a plurality of light emitting members can be utilized and controlled by the control circuit board 310 and programs. The light emitting members can be disposed in different positions on the lens 100 to emit different color light for providing different functions and meanings.

Referring to FIG. 9, in another embodiment of the invention, the lens 100 of the sight structure has a surface 110 on which a first aiming pattern, a second aiming pattern and a third aiming pattern are formed. In this embodiment, the first aiming pattern is a reticle, with a first light emitting member 200 disposed at a center thereof. It is noted that two electrodes 120 constitute a set of opposite arms of the reticle (the first aiming pattern), and two electrodes 140 constitute another set of opposite arms of the reticle. The second aiming pattern is a first rectangle, with four second light emitting members 210 respectively disposed at four corners thereof. Two electrodes 120′ and 140′ are disposed on two perpendicular sides of the second aiming pattern and connected to the second light emitting members 210 respectively. The electrodes 120′ constitute a set of opposite sides of the first rectangle, and the electrodes 140′ constitute another set of opposite sides of the first rectangle. Thus, the second light emitting members 210 emit light when current flows to the second light emitting members 210 through the electrodes 120′ and 140′. The third aiming pattern is a second rectangle which is bigger than the first rectangle. Similarly, four third light emitting members 220 are respectively disposed at four corners of the second rectangle. Similarly, two electrodes 120″ and 140″ are disposed on two perpendicular sides of second aiming pattern and connected to the third light emitting members 220. The third light emitting members 220 emit light when current flows to the third light emitting members 220 through the electrodes 120″ and 140″.

In practical operation, different scales (not shown) formed at an outer surface of the power supply module 190 is indicated to different light emitting modes. For example, once a first scale is selected, the control circuit board 310 controls current to flow through the electrodes 120 and 140 of the first aiming pattern, and the first emitting member 200 emits light. Thus, the user is reminded that a field of view referring to the first scale includes the visible region of the lens 100. The second emitting members 210 emit light when a second scale is selected, and the user is reminded that a field of view referring to the second scale includes the visible region within the first rectangle (the second aiming pattern). The third emitting members 220 emit light when a third scale is selected, and the user is reminded that a field of view referring to the third scale includes the visible region within the second rectangle (the third aiming pattern). It is understood that the first emitting member 200, the second emitting members 210 and/or the third emitting members 220 can be selected to emit light in accordance with different requirements.

In another embodiment, the second aiming pattern and the third aiming pattern are not geometrically similar. Specifically, the second aiming pattern is a rectangle and the third aiming pattern is a rhombus which encloses the rectangle.

In the invention, the first light emitting member 200 is disposed on the surface 110 of the lens 100 and the first aiming pattern is composed of the electrodes 120 and 140. Thus, no external light source is needed, the size of the sight structure can be reduced, and a higher brightness can be provided. In addition, a plurality of light emitting members 210 and 220 can be disposed in different positions of the lens 100 to provide different functions.
