[0043] A retractable block 34 is provided at one end of the connector 3 away from the connector seat 31 , and an electromagnetic telescopic rod is provided inside the connector 3 , the telescopic end of the electromagnetic telescopic rod is fixedly connected to the block 34 , and the electromagnetic telescopic rod is used to drive the block 34 to move.

[0044] A rotating shaft 6 is rotatably installed on one side of the lamp housing 1 close to the connecting member 3. A driving box 9 is provided inside the lamp housing 1. A motor module for driving the rotating shaft 6 to rotate is installed inside the driving box 9. A guide cylinder 61 is fixedly installed on the surface of the rotating shaft 6. A limiting groove 611 is axially provided on the surface of the guide cylinder 61. When the clamping block 34 extends out of the connecting seat 31, it cooperates with the limiting groove 611. When the clamping block 34 cooperates with the limiting groove 611, the rotation of the guide cylinder 61 will drive the connecting member 3 to rotate together, thereby driving the lamp unit 4 to rotate together.

[0045] The connecting member 3 can rotate around the rotating shaft 6. When the connecting member 3 rotates around the rotating shaft 6, the lamp unit 4 can cooperate with the opening on the bottom surface of the lamp housing 1. When several lamp units 4 are matched with the opening, several lamp units 4 are combined to form a lighting lamp surface. This is the normal use state of the lighting device.

[0046] An adjusting screw rod 1 7 and an adjusting screw rod 2 8 are rotatably installed inside the lamp housing 1 , a motor module for independently driving the adjusting screw rod 1 7 and the adjusting screw rod 2 8 to rotate is installed inside the driving box 9 , and the connecting member 3 is located between the adjusting screw rod 1 7 and the adjusting screw rod 2 8 .

[0047] A semi-annular connecting ring 32 is provided on one side of the connecting member 3 close to the adjusting screw rod 7. The connecting ring 32 is radially slidably provided with a semi-annular threaded ring 321. A spring is provided between the threaded ring 321 and the inner ring surface of the connecting ring 32. The spring is used to make the threaded ring 321 and the adjusting screw rod 7 threadably engage with each other. When the adjusting screw rod 7 and the connecting ring 32 cooperate to drive the light unit 4 to move, the threaded ring 321 is designed so that the light unit 4 will no longer move with the rotation of the adjusting screw rod 7 when the movement is blocked.

[0048] A semi-annular connecting ring 2 33 is provided on one side of the connecting member 3 close to the adjusting screw rod 2 8.

The adjusting screw rod 2 8 cooperates with the connecting ring 2 33 to drive the light unit 4 separated from the opening to move along the axial direction of the adjusting screw rod 2 8, so as to adjust the position of the light unit 4.

[0049] When the lamp unit 4 is in a matched state with the opening, the connecting ring 32 is in a matched state with the adjusting screw rod 7. By utilizing the matching of the adjusting screw rod 7 and the connecting ring 32, the lamp unit 4 matched with the opening can be driven to move along the axial direction of the adjusting screw rod 7, thereby adjusting the position of the lamp unit 4. In conjunction with the above-mentioned lamp unit 4 that needs to be adjusted, the position of the lamp unit 4 in the lighting lamp surface can be replaced.

[0050] The connecting member 3 can move along the axial direction of the rotating shaft 6, wherein one or more connecting members 3 are rotated to a set angle in the direction away from the opening (after rotating to this angle, the forward projection of the connecting member 3 and the lamp unit 4 on its surface in the axial direction has no overlap with the forward projection of the lamp unit 4 inside other lighting surfaces and the connected connecting members 3), and the position of the connecting member 3 is replaced by moving along the axial direction of the rotating shaft 6, and all the lamp units 4 are matched with the opening to form a new lighting surface. By adopting this method, the damaged lamp unit 4 can be replaced to the side position of the lighting surface, and the lamp units 4 that can be used normally can be arranged continuously to ensure the lighting effect of the lighting device.

[0051] A guide plate 10 is fixedly mounted on the side surface of the lamp housing 1 away from the rotating shaft 6 . A plurality of vertical guide grooves 101 are formed on the surface of the guide plate 10 . Horizontal guide grooves 102 are formed at both upper and lower ends of the vertical guide grooves 101 . The horizontal guide grooves 102 penetrate all the vertical guide grooves 101 .

[0052] A guide rod 42 is fixedly installed at one end of the light sheet unit 4 close to the guide plate 10, and the free end of the guide rod 42 is located in the vertical guide groove 101 or the transverse guide groove 102. The guide rod 42 cooperates with the vertical guide groove 101 to improve the stability of the connecting piece 3 and the light sheet unit 4, and the guide rod 42 cooperates with the transverse guide groove 102 to improve the stability of the axial movement of the connecting piece 3 and the light sheet unit 4.

[0053] An electric connection plate is fixedly mounted on one side of the lamp housing 1 away from the rotating shaft 6. A plurality of groups of hemispherical electric connectors 2 5 are arranged on the surface of the electric connection plate. The electric connectors 2 5 are connected to the power supply device.

[0054] An electric socket 41 is fixedly installed at one end of the light unit 4 away from the connecting piece 3, and a retractable hemispherical electric connector 1 411 is provided inside the electric socket 41, and a spring member is provided between the electric connector 1 411 and the electric socket 41. When the light unit 4 is matched with the opening, the electric connector 2 5 is pressed against the electric connector 1 411, and the light module inside the light unit 4 can be connected to the power supply.

[0055] Windows are provided on both sides of the lamp housing 1 in the width direction, and a filter screen 11 is fixedly installed inside the window to prevent mosquitoes, leaves and other large-volume objects from entering the lamp housing 1. A ventilation box 12 is fixedly installed on the inner side of the filter screen 11, and a support plate 13 is fixedly installed inside the ventilation box 12. Several groups of ventilation parts 14 are arranged inside the ventilation box 12, and both sides of the ventilation parts 14 pass through the ventilation box 12. The ventilation parts 14 on one side of the lamp housing 1 are used to introduce airflow into the interior of the lamp housing 1 and export it from the ventilation parts 14 on the other side, so as to perform air cooling and heat dissipation on the interior of the lamp housing 1.

[0056] The ventilation member 14 is composed of two trumpet-shaped ventilation pipes. A spring is provided between the outer ring surface of the ventilation pipe and the ventilation box 12 for resetting the ventilation pipe. The small ends of the two ventilation pipes are connected. When the airflow outside the lamp housing 1 passes through the trumpet-shaped ventilation pipe, the airflow velocity will increase, which is used to increase the fluidity of the airflow when it enters the interior of the lamp housing 1. The inner surface of the ventilation pipe close to the filter plate 11 is a dust-absorbing material. The dust-absorbing material can be silica gel or wool fiber. The design of the trumpet-shaped ventilation pipe can increase its contact with the airflow, thereby utilizing the adsorption material to absorb dust particles in the airflow.

[0057] The small ends of the two ventilation pipes in the same group are connected by a flexible connection channel 141. The flexible connection channel 141 can be a rubber hose or a retractable bellows. The flexible connection channel 141 in the ventilation member 14 is fixedly connected to the support plate 13.

[0058] A limit plate 142 is fixedly installed on the surface of the ventilation pipe, and a limit hole is provided on the surface of the limit plate 142. An adjustment plate 15 is slidably installed inside the ventilation box 12 along its thickness direction. An adjustment rod 16 is installed inside the ventilation box 12. The adjustment rod 16 is an electromagnetic telescopic rod. The adjustment plate 15 is driven to move by the adjustment rod 16. A plurality of limit rods 151 are fixedly installed on the surface of the adjustment plate 15. The limit rod 151 is located between the limit plates 142 on the surfaces of two ventilation pipes in the ventilation component 14. When one end of the limit rod 151 cooperates with the limit hole on the surface of one of the limit plates 142 in the ventilation component 14, the other end is separated from the limit hole on the surface of the other limit plate 142.

[0059] When the limiting rod 151 cooperates with the limiting hole on the surface of the limiting plate 142, the movement of the corresponding ventilation pipe in the radial direction is restricted. When the limiting rod 151 and the limiting hole on the surface of the limiting plate 142 are in a separated state, the ventilation pipe cooperates with the flexible connecting pipe to have freedom of movement in multiple directions. The ventilation pipe is used on the outer side of the ventilation box 12 on the side where the airflow enters the lamp housing 1, which can reduce its resistance to the airflow and improve the effect of the airflow entering the interior of the lamp housing 1. The movement of one of the ventilation pipes on both sides of the support plate 13 inside the ventilation box 12 is restricted in the radial direction, while the other is not restricted, so as to avoid the two ventilation pipes from moving in the opposite direction in the radial direction, thereby causing radial misalignment of the internal channel of the ventilation piece 14, thereby affecting the fluidity of the ventilation piece 14.

[0060] Working principle of the lighting device:

[0061] During normal use, all the lamp units 4 are in a matched state with the opening at the bottom of the lamp housing 1, and all the lamp units 4 are combined to form a lighting lamp surface. At this time, the electrical connector 1 411 inside the electrical socket 41 in the lamp unit 4 is in contact with the corresponding electrical connector 2 5, and the lamp unit 4 can be connected to the power supply. By turning on the lamp unit 4, the power can be turned on, and the lighting lamp surface lights up to achieve lighting.

[0062] When the light unit 4 at the side of the bottom opening of the lamp housing 1 is damaged, there is no need to adjust the position of the light unit 4. When there are normally lit light units 4 on both sides of the damaged light unit 4, the position of the damaged light unit 4 needs to be adjusted. For details, refer to Figure 3 and Figure 4 The electromagnetic telescopic rod inside the connecting piece 3 corresponding to the lamp unit 4 is used to drive the corresponding block 34 to extend out of the connecting piece 3, and make it cooperate with the limiting groove 611 on the surface of the guide cylinder 61, and the motor module inside the driving box 9 is used to drive the guide cylinder 61 to rotate. The guide cylinder 61 drives the connecting piece 3 to rotate together through the cooperation between the limiting groove 611 and the block 34.

[0063] The connecting piece 3 drives the damaged light sheet unit 4 to rotate together, and at the same time, with the cooperation of the guide rod 42 and the vertical guide groove 101, the stability of the rotation of the light sheet unit 4 is guaranteed until the connecting piece 3 and the light sheet unit 4 rotate to the set angle. At this time, the connecting ring 2 33 on the surface of the connecting piece 3 and the adjusting screw 2 8 are in a threaded connection state, and the motor module inside the driving box 9 is used to drive the adjusting screw 2 8 to rotate, thereby driving the connecting piece 3 and the damaged light sheet unit 4 to move axially, and move the light sheet unit 4 to the sidemost position of the opening.

[0064] At the same time, the motor module inside the driving box 9 is used to drive the adjusting screw rod 7 to rotate. At this time, the threaded ring 321 in the connecting ring 32 on the surface of the connecting piece 3 corresponding to the lamp unit 4 that cooperates with the opening is in a threaded connection state with the adjusting screw rod 7. The position of the originally damaged lamp unit 4 is vacant. By rotating the adjusting screw rod 7, all the lamp units 4 on the side of the vacant part close to the moving direction of the damaged lamp unit 4 are driven to move in the direction of the vacant part. The lamp unit 4 on the other side of the vacant part is blocked from moving, resulting in radial sliding of the threaded ring 321 inside the connecting ring 32 in the corresponding connecting piece 3, causing the threaded connection between the threaded ring 321 and the adjusting screw rod 7 to be unable to be normally threadedly connected. Therefore, the lamp unit 4 on this side will not move until the movable lamp unit 4 fills the above-mentioned vacant part. At this time, the movement of the moving lamp unit 4 is also blocked and it no longer moves, and at the same time, the driving of the adjusting screw rod 7 to rotate is stopped.

[0065] Then, by driving the rotating guide cylinder 61, the damaged lamp unit 4 can be rotated to the empty space at the side of the opening. By adopting the above method, all damaged lamp units 4 can be adjusted to the side of the opening, so that all normally lit lamp units 4 can be continuously arranged together, thereby realizing centralized lighting.

[0066] When the lighting device is in use, the airflow passes through the filter plate 11 on one side of the lamp housing 1 and enters the ventilation piece 14 in the ventilation box 12. At this time, the movement of the ventilation pipe close to the filter plate 11 is not restricted by the limiting rod 151 to reduce its resistance to the airflow. The airflow enters the interior of the lamp housing 1 through the ventilation piece 14, and flows out through the ventilation piece 14 in the ventilation box 12 on the other side. In the ventilation box 12 on the export side, the movement of the ventilation pipe close to the interior of the lamp housing 1 is not restricted by the limiting rod 151 to reduce the resistance of the airflow when it is exported, which facilitates the airflow to flow out of the lamp housing 1, thereby achieving heat dissipation inside the lamp housing 1.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
