[0030] The embodiment of the present utility model discloses a flexible dimming device for an LED lighting system.

[0031] Embodiment 1

[0032] The present utility model provides as Figures 1-5A flexible dimming device for an LED lighting system shown in the figure includes a lamp post 1 and an LED lamp body 2 fixedly arranged at the upper end of the outer wall of the lamp post 1. There are two symmetrically arranged light filters 3 on the outside of the LED lamp body 2. The cross-sections of the two light filters 3 are both arc-shaped. There are two symmetrically arranged arc-shaped plates 4 fixedly arranged between the two light filters 3. A baffle 18 is fixedly arranged on the side of the two light filters 3 and the arc-shaped plates 4 away from the lamp post 1. A first air duct opening is formed inside the arc-shaped plate 4. A first gasket 5 and a second gasket 6 are respectively arranged in contact with the two sides of the arc-shaped plate 4 away from each other. At both ends of the inside of the first gasket 5 and the second gasket 6, support rods 13 are fixedly inserted. The sides of the first gasket 5 and the second gasket 6 close to each other are both arc-shaped and are in contact and fit with the outer wall of the arc-shaped plate 4. A plurality of support rods 13 are all fixedly connected to the outer wall of the lamp post 1. A second air duct opening is formed inside the first gasket 5 and the second gasket 6. An exhaust fan 7 is fixedly arranged on the outer wall of the first gasket 5. A dust-proof net 8 is covered on the outside of the second gasket 6.

[0033] When the LED lamp body 2 is operating, the two light filters 3 can be rotated to quickly dim the LED lighting component. When the LED lamp body is operating, the exhaust fan 7 keeps working, which can make the heat flow inside the light filter 3 quickly transfer to the outside through the exhaust fan 7. At the same time, the external cooling air flow enters the inside of the second gasket 6 through the dust-proof net 8 and enters the light filter 3 through the second air duct opening inside the second gasket 6, ensuring the rapid exchange of the air flow inside the light filter 3 and enabling the stable operation of the LED lighting component. Since the arc-shaped plate 4 is in close contact with the first gasket 5 and the second gasket 6, dust and sundries outside cannot enter the inside of the light filter 3 during use, ensuring the stability of the light irradiated by the lighting component.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, in order to be able to drive the two light filters 3 to rotate stably to complete the dimming work, as Figures 1-2 and Figure 4 shown, a rotation groove 9 for the rotation of the two light filters 3 is formed at the upper end of the outer side of the lamp post 1. The two light filters 3 are rotationally matched with the upper end inside the lamp post 1 through the bearings on their outer sides. A drive dimming mechanism is arranged on the outer sides of the two light filters 3. The drive dimming mechanism includes a gear ring 10. The gear ring 10 is fixedly sleeved on the outer sides of the two light filters 3. An electric push rod 11 is fixedly arranged at the upper end of the outer wall of the lamp post 1. A rack 12 is fixedly arranged on the output shaft of the electric push rod 11. The rack 12 is arranged in cooperation with the gear ring 10.

[0036] When it is necessary to drive the two light filters 3 and complete the dimming work, the electric push rod 11 can be controlled to start, so that the electric push rod 11 pushes the rack 12. Through the cooperation of the rack 12 and the gear ring 10, the two light filters 3 can rotate stably under the cooperation of the bearings and the rotating grooves 9, so as to complete the position adjustment of the two light filters 3 and complete the dimming work.

[0037] Embodiment 3

[0038] On the basis of Embodiment 1, in order to be able to replace the dust-proof net 8 after the lighting system has been used for a long time, as Figures 2-3 shown, connecting plates 14 are fixedly arranged on both sides of the dust-proof net 8. A positioning rod 15 is slidably inserted through the outer wall of the connecting plate 14. A positioning groove is formed in the outer wall of the second gasket 6. The end of the positioning rod 15 is inserted into the positioning groove. A spring 16 is sleeved on the rod wall of the positioning rod 15. Both ends of the spring 16 are fixedly connected to the positioning rod 15 and the connecting plate 14 respectively. Pulling rings 17 are fixedly arranged at the ends of the two positioning rods 15 away from each other.

[0039] After the lighting system has been used for a long time, an external tool can be used to pull the two pulling rings 17, so that the pulling rings 17 drive the positioning rod 15 to move, so that the positioning rod 15 stretches the spring 16 while moving away from the positioning groove. When the positioning rod 15 is completely pulled out of the positioning groove, the dust-proof net 8 can be removed from the outside of the second gasket 6, and a new dust-proof net 8 can be installed. Then, the positioning rod 15 is inserted into the positioning groove again through the elastic recovery of the spring 16, so as to complete the installation of the dust-proof net 8, so that the overall lighting system can continue to operate stably.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
