A through groove 36 is provided at the rear end of the upper surface of the movable shell 31. The inner wall of the movable shell 31 is adapted to the dimming plate 4 to ensure the stability of the connection of the dimming plate 4. The dimming plate 4 is plugged into the inner wall of the movable shell 31. The lower part of the dimming plate 4 is in the shape of a round block to adapt to the inner hole of the concentrator 1, and the upper part is in the shape of a strip, which protrudes outward to facilitate the taking of the dimming plate 4.

[0034] Reference Figure 2 , Figure 5 , Figure 6 The fixing component 7 includes a rectangular plate 74, which is slidably connected to the inner wall of the through groove 36. A blocking block 75 is fixedly connected to the lower surface of the rectangular plate 74. Under the action of the spring 2 72, the lower surface of the blocking block 75 is always in contact with the upper surface of the dimming plate 4, preventing the dimming plate 4 from shaking and moving up and down, thereby improving stability. The blocking block 75 is slidably connected to the inner wall at the bottom end of the through groove 36.

[0035] Reference Figure 2 - Figure 3 The heat dissipation assembly 5 includes a heat dissipation fan 51. The heat dissipation fan 51 is in the prior art. Its principle is to blow air away from the heat source to increase the air flow on the surface of the heat source, thereby promoting heat transfer. The heat dissipation fan 51 passes through and is fixedly connected to the rear surface of the left end of the rectangular shell 2. A heat dissipation hole 52 is opened at the left end of the front surface of the rectangular shell 2.

[0036] Reference Figure 2 , Figure 4The right end of the upper surface of the movable shell 31 is fixedly connected with a push rod 35, and the inner wall of the groove 1 32 is elastically connected to the limit block 34 through a spring 1 33. The spring 1 33 itself has a certain elasticity, and it will always push the limit block 34 to move forward through its own elasticity to ensure that the limit block 34 always contacts the inner wall of the groove 2 6 without pushing the movable shell 31, thereby ensuring the stability of the limit. The limit block 34 is slidably connected to the inner wall of the groove 1 32, one end of the spring 1 33 is fixedly connected to the inner wall of the groove 1 32, and the other end of the spring 1 33 is fixedly connected to the rear surface of the limit block 34, and the front surface of the limit block 34 contacts the inner wall of the groove 2 6. The front surface of the limit block 34 is set to an arc surface, and the set arc surface ensures that the limit block 34 can fix the movable shell 31, but will not jam it, thereby improving the convenience of adjustment.

[0037] Reference Figure 2 , Figure 5 - Figure 6 The fixing assembly 7 also includes a concave shell 71, which is fixedly connected to the rear end of the upper surface of the moving shell 31. The inner wall of the concave shell 71 is elastically connected to a connecting strip 73 through a spring 2 72. The spring 2 72 itself has a certain elasticity. It always pushes the connecting strip 73 to move forward through its own elasticity to ensure the stability of the limiting position of the blocking block 75. The right end of the lower surface of the connecting strip 73 is fixedly connected to the upper surface of the rectangular plate 74. The upper surface of the blocking block 75 is set as an inclined surface, and the lower surface is set as an arc surface.

[0038] Reference Figure 1 - Figure 3 There are multiple groups of heat dissipation components 5, and the multiple groups of heat dissipation components 5 are symmetrically arranged with the center line of the concentrator 1 as the symmetry axis. The multiple groups of heat dissipation components 5 can improve the convenience of replacing the dimming plate 4.

[0039] Working principle: When the condenser 1 is needed for photography, the dimming plate 4 to be used can be directly inserted into the inner wall on the left side of the movable shell 31, so that the light source irradiated by the condenser 1 can be adjusted, and the dimming plate 4 to be replaced later can be placed on the inner wall on the right side of the movable shell 31 in advance. When the dimming plate 4 needs to be replaced, it is only necessary to push the push rod 35, and the push rod 35 will drive the movable shell 31 to move. At this time, the limit block 34 will be separated from the inner wall of the groove 2 6 through its own arc surface, and the limit block 34 will squeeze the spring 1 33 and completely enter the groove 1 32. The inner wall is moved until the limit block 34 overlaps with another set of grooves 2 6. At this time, the spring 1 33 will push the limit block 34 to move in the opposite direction and enter the inner wall of the groove 2 6 through its own elasticity, so that the dimming board 4 can be replaced. At the same time, the used dimming board 4 will move to the front side of the cooling fan 51. At this time, the cooling fan 51 is started to dissipate the heat of the used dimming board 4, and the hot air will flow out through the cooling holes 52. In this way, the photographer does not need to pull out the used dimming board 4 immediately, and can wait until the heat on its surface dissipates before replacing it, so as to avoid burns, thereby improving practicality.

[0040] When the locking cam 73 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 is locked.
