2. The lighting fixture according to claim 1 , wherein:
the anti-deformation assembly further comprises an elastic clip;
one end of the connection rib is connected to the lens unit, and the other end of the connection rib penetrates the connection through-hole and is in snap fit with the elastic clip; and
the elastic clip is abutted against the light source panel.

3. The lighting fixture according to claim 2 , wherein:
the elastic clamping member comprises a clamping gap;
one end of the connection rib is connected to the lens unit, and the other end of the connection rib penetrates the connection through-hole and is inserted into the clamping gap; and
the elastic clamping member is abutted against the light source panel and applies a clamping force to the connection rib.

4. The lighting fixture according to claim 3 , wherein:
the clamping gap is formed between the first clamping piece and the second clamping piece.

5. The lighting fixture according to claim 4 , wherein an amount of at least one of: the first clamping piece and the second clamping piece is multiple.

6. The lighting fixture according to claim 5 , wherein the first clamping piece and the second clamping piece are in staggered arrangement.

7. The lighting fixture according to claim 4 , wherein a lateral dimension of the clamping gap is gradually reduced in a direction gradually away from the light source panel, and the lateral direction is parallel to a direction in which the first clamping piece and the second clamping piece face each other.

8. The lighting fixture according to claim 2 , wherein:
the elastic clip comprises a strip body portion, and a first snap-fit portion and a second snap-fit portion which are at two ends of the strip body portion;
the first snap-fit portion and the second snap-fit portion are opposite to each other to form a snap-fit gap therebetween;
the connection rib is locked in the snap-fit gap; and
both a joint between the strip body portion and the first snap-fit portion and a joint between the strip body portion and the second snap-fit portion are abutted against the light source panel.

9. The lighting fixture according to claim 8 , wherein:
the connection rib comprises a connection portion and a fastening portion;
the fastening portion is connected to the lens unit through the connection portion, and has a fastening surface protruding relative to the connection portion and a V-shaped guide surface connected to the fastening surface;
the fastening surface is abutted against the first snap-fit portion and the second snap-fit portion; and
the V-shaped guide surface is on a side, away from the light source panel, of the fastening surface.

10. The lighting fixture according to claim 8 , wherein a lateral dimension of the snap-fit gap is gradually reduced in a direction gradually away from the light source panel, and the lateral direction is parallel to a direction in which the first snap-fit portion and the second snap-fit portion face each other.

11. The lighting fixture according to claim 8 , wherein the strip body portion is of a U-shaped structure.

12. The lighting fixture according to claim 1 , wherein a seal is between the housing and the lens cover; the lens cover is provided with a second sealing groove, the seal is in the second sealing groove, and a vent hole runs through to a top edge of the second sealing groove.

13. The lighting fixture according to claim 1 , wherein the lighting fixture comprises a street lamp.

14. The lighting fixture according to claim 1 , wherein the connection rib applies action forces to the first clamping piece and the second clamping piece, and the first clamping piece and the second clamping piece deform to apply reaction forces to the connection rib.

15. A method of manufacturing a lighting fixture, comprising:
providing a housing, a light source assembly, a lens cover, and an anti-deformation assembly;
connecting the housing with the lens cover to form a mounting space;
mounting the light source assembly in the mounting space and providing the light source assembly with a light source panel, and a connection through-hole in the light source panel;
providing the lens cover with a cover body and a lens unit on the cover body;
providing a part of the anti-deformation assembly in the connection through-hole, and connecting the anti-deformation assembly to the lens unit to apply an action force to the lens unit to cause the lens unit to fit the light source panel;
providing a connection rib and an elastic clamping member in the anti-deformation assembly;
