One convex lens 4 is arranged on one side of the lamp strip 3. One cam 9 for adjusting the distance of the convex lens 4 according to the thickness of the lamp strip 3 is arranged above each of the two clamping plates 10. The lamp strip wiring structure further comprises a lead screw 8 and a sliding groove 11. Two sliding grooves 11 are formed in the cavity of the suspension plate 2 on both sides. The end of each of the two clamping plates 10 is slidably connected with one sliding groove 11. One lead screw 8 is arranged on each side of the two clamping plates 10 away from each other. One end of each of the two lead screws 8 is rotatably connected with one clamping plate 10. The two lead screws 8 pass through the outer wall of the circuit frame 1 and each pass through one cam 9. The two lead screws 8 are threadedly connected with the circuit frame 1 and the cam 9 respectively. The lamp strip wiring structure further comprises a fixed plate 5 and a transmission block 12. One side of each of the two fixed plates 5 is fixedly connected with one side of the convex lens 4. One transmission block 12 is fixedly arranged on one side of each of the two fixed plates 5. Each of the two transmission blocks 12 can abut against one cam 9. The lamp strip wiring structure further comprises a first telescopic rod 6, a second telescopic rod 7 and a first spring 13. One first telescopic rod 6 and one second telescopic rod 7 are fixedly arranged at the two ends of each of the two fixed plates 5. One end of the second telescopic rod 7 is fixedly connected with the corresponding fixed plate 5. The second telescopic rod 7 extends into the cavity of the first telescopic rod 6 and is slidably connected with the first telescopic rod 6. The extending end of the second telescopic rod 7 is fixedly connected with one end of the first spring 13.

The two lead screws 8 drive the two clamping plates 10 to approach each other and abut the upper and lower sides of the lamp strip on the inner wall of the circuit frame 1. The two lead screws 8 drive the two cams 9 to rotate and descend at the same time. The thinner the lamp strip is, the more the lead screw 8 rotates, and the lower the cam 9 descends. When the lamp strip is clamped and fixed by the clamping plate 10, the end of the cam 9 abuts against the cylinder in the middle part of the transmission block 12, drives the fixed plate 5, the convex lens 4 and the second telescopic rod 7 to stretch forward, and the convex lens 4 moves away from the thin lamp strip. According to the imaging principle of the convex lens 4, as the convex lens moves away from the light source, the object distance gradually increases. When the object distance is still less than the focal length, the image is still an erect and enlarged virtual image. The light of the thin lamp strip is enlarged and softened. When watching the TV set, the background lamp strip behind will not be eye-catching. If the size of the lamp strip is not enough to make the end of the cam 9 rotate to abut against the transmission block 12, press the lead screw 8 not to rotate, rotate the cam 9, make the cam 9 rotate around the lead screw 8, and abut against the transmission block 12.
