wherein the clamping lug comprises:

a stopper part provided with a protrusion that is clamped in the clamping slot, and

a guide part that is moved in the clamping slot to guide the protrusion, wherein the stopper part is provided separately from the guide part.

2. A lens module of an LED lamp, comprising:

a chassis provided with a mounting slot; and

a lens body fixed in the mounting slot through a clamping lug and a clamping slot, wherein, after moving the lens body along the mounting slot, the clamping lug is clamped in the clamping slot; and

an LED light source provided on the lens body,

wherein the clamping lug comprises:

a stopper part provided with a protrusion that is clamped in the clamping slot, and

a guide part that is moved in the clamping slot to guide the protrusion, wherein the stopper part is provided separately from the guide part.

3. The lens module according to claim 2 , wherein the guide part and the stopper part are both located at a same side of the lens body, and are protruded out of the lens body toward the same side of the lens body.

4. The lens module according to claim 2 , wherein the guide part comprises:

a guide part body that is connected with the lens body and is moved in the clamping slot, and

a receiving hole that is provided at a front end of the guide part body and is provided to receive the stopper part.

5. The lens module according to claim 4 , wherein the stopper part comprises a stopper part body, of which a front end is connected with a front wall of the receiving hole, wherein the protrusion is provided at a rear end of the stopper part body.

6. The lens module according to claim 5 , wherein the guide part body and the stopper part body are both in plate-shaped structures.

7. The lens module according to claim 5 , wherein the clamping slot comprises:

a first clamping slot part that is configured to place the guide part body and is recessed, and

a second clamping slot part that is located in front of the first clamping slot part and is provided with the protrusion, and

wherein the first clamping slot part is spaced from the second clamping slot part, and a front side wall of the first clamping slot part is provided with an insertion opening, into which the guide part body is inserted.

8. The lens module according to claim 2 , wherein:

the lens body has an annular shape wherein the mounting slot is recessed toward an inside of the chassis and has an annular shape that is adapted to the annular shape of the lens body, and the clamping slot is provided on a bottom wall of the chassis; and

after rotating the lens body around the mounting slot, the clamping lug is clamped in the clamping slot.

9. The lens module according to claim 8 , wherein at least three clamping lugs and clamping slots that are matched with each of the at least three clamping lugs are provided along a circumferential direction of the lens body.

10. A method of manufacturing a lens module of an LED lamp, comprising:

providing a chassis with a mounting slot;

providing an LED light source on a lens body;

fixing the lens body in the mounting slot through a clamping lug and a clamping slot;

clamping the clamping lug in the clamping slot after moving the lens body along the mounting slot,

providing a stopper part for the clamping lug with a protrusion that is clamped in the clamping slot; and

providing a guide part for the clamping lug wherein the guide part is moved in the clamping slot to guide the protrusion, and the stopper part is provided separately from the guide part.

11. The method according to claim 10 , further comprising:

obtaining an annular shape for the lens body wherein the mounting slot is recessed toward an inside of the chassis and has an annular shape that is adapted to the annular shape of the lens body, and the clamping slot is provided on a bottom wall of the chassis; and

claiming the clamping lug in the clamping slot after rotating the lens body around the mounting slot.
