Optical binoculars

1. An optical binocular, comprising:

a main body;

a lens module, disposed on a side of the main body;

a display module, disposed in the main body and electrically connected to the lens module, and configured to display an image captured by the lens module;

a first light source assembly, including a first light source and a first lens, and configured to emit a first light; and

a second light source assembly, including a second light source, a second lens, and a condensing cup body, and configured to emit a second light;

wherein the first light source assembly and the second light source assembly are respectively disposed on two sides of the lens module, the first light source emits a long-range light through the first lens, and the second light source emits a close-range light through the second lens, wherein the focal length of the first lens is greater than the focal length of the second lens; and

wherein the first lens is a plano-convex lens, the first light source emits the long-range light through the plano-convex lens, the second lens is a convexo-plane lens, the second light source irradiates the close-range light through the convexo-plane lens, and the convexo-plane lens is disposed in the condensing cup body.

2. The optical binocular as claimed in claim 1 , wherein there is a space between the first light source and the first lens, and the space has a tapered structure.

3. The optical binocular as claimed in claim 1 , wherein there is a first distance between the first light source and the first lens, and the first distance is from 18 to 20 mm.

4. The optical binocular as claimed in claim 3 , wherein there is a second distance between the second light source and the second lens, and the second distance is from 4.5 to 5.5 mm.

5. The optical binocular as claimed in claim 4 , wherein the first distance is greater than the second distance by at least 12.5 mm.

6. The optical binocular as claimed in claim 1 , further including an eyepiece assembly, and the main body includes a first side and a second side, and the first side is opposite the second side, the lens module, wherein the first light source assembly and the second light source assembly are disposed on the first side, and the eyepiece assembly is disposed on the second side.

7. The optical binocular as claimed in claim 6 , wherein in the direction of an optical axis of the lens module, the display module is disposed between the lens module and the eyepiece assembly.

8. The optical binocular as claimed in claim 6 , wherein the eyepiece assembly has an eyepiece lens, and the eyepiece lens is a biconvex lens.

9. The optical binocular as claimed in claim 6 , wherein there is an observation room between the display module and the eyepiece assembly, the observation room has a first opening and a second opening, the first opening is adjacent to the eyepiece assembly, the second opening is adjacent to the display module, wherein the second opening is smaller than the first opening.

10. The optical binocular as claimed in claim 9 , wherein the observation room has an inner wall, and the inner wall has a scattering structure.

11. The optical binocular as claimed in claim 1 , further comprising a plurality of buttons disposed on the upper side of the body, wherein the buttons are configured to operate the lens module, the display module, the first light source assembly and the second light source assembly.

12. The optical binocular as claimed in claim 1 , wherein the display module has a liquid-crystal display (LCD) panel.
