[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 4 As shown, the utility model provides a full-field microscope illumination light source, in one embodiment, including

[0025] A mounting tube 1, wherein the interior of the mounting tube 1 is an axially hollow structure;

[0026] The connecting base 2 is installed in the upper part of the mounting tube 1, and the top of the connecting base 2 is provided with a connecting groove 21 for connecting to the microscope; the bottom of the connecting groove 21 is further provided with a first through hole 22 that penetrates into the mounting tube 1;

A fixing block 31 extends upward from the middle of the top of the lighting base 3, and a second through hole 32 is formed at the top of the fixing block 31 corresponding to the first through hole 22 and extending into the lighting base 3.

[0028] A lighting assembly, the lighting assembly includes a first lamp board 41 and at least one second lamp board 42; the first lamp board 41 is installed on the fixed block 31, and a third through hole 43 is opened at the top of the first lamp board 41 corresponding to the first through hole 22, which passes through the second through hole 32; a plurality of first lamp beads are installed at intervals on the bottom circumference of the first lamp board 41; the first lamp beads are arranged in the second through hole 32, and the first lamp beads are used to emit light beams outward in a direction perpendicular to the horizontal plane; the inner wall of the lighting seat 3 is provided with at least one annular limit groove 33 along its circumference, and the inner wall of the limit groove 33 is provided with an inclined surface with a predetermined inclination angle to the horizontal plane; the second lamp board 42 is annular in structure, and the second lamp board 42 is installed on the inclined surface; a plurality of second lamp beads are installed on one side of the second lamp board 42, and the second lamp beads are used to emit light beams outward at a predetermined inclination angle to the horizontal plane.

[0029] In this embodiment, a connecting groove 21 is provided on the top of the connecting seat 2, and the lens of the microscope can be inserted into the connecting groove 21 to connect thereto. The first lamp board 41 and the second lamp board 42 can be LED lamp boards, and the first lamp bead and the second lamp bead are LED lamp beads. The first lamp board 41 is annular in structure (axially hollow, that is, a third through hole 43 is provided, and the third through hole 43 is arranged corresponding to the lens of the microscope, which is convenient for users to use the microscope to detect products). The first lamp bead at the bottom of the first lamp board 41 can emit a light beam outward in the vertical direction (that is, to achieve 90° irradiation); the inclination angle of the inclined surface on the inner wall of the limiting slot 33 can be set by yourself according to actual use requirements.
