Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0054] Please see Figures 1-8 In one embodiment of this application, an LED lighting fixture for urban rail transit includes a mounting base 1, a lampshade 2, a movable base 3, a plurality of bulbs 4, and a lamp holder 5. The lamp holder 5 is detachably and movably disposed within the mounting base 1, the plurality of bulbs 4 are movably disposed on the lamp holder 5, the movable base 3 is movably disposed on the lamp holder 5 and the two are elastically connected, the lampshade 2 is disposed on the lamp holder 5, and the LED lighting fixture further includes:

[0055] A locking structure is provided between the mounting base 1 and the lamp holder 5 to fix the lamp holder 5 inside the mounting base 1;

[0056] An adjustment system, located between the movable seat 3 and the lamp holder 5, is used to monitor the subway speed and adjust the intensity and range of the lights; and

[0057] A cleaning component is disposed between the movable base 3 and the lamp holder 5. When the lamp cover 2 is displaced by the impact of airflow, the cleaning component is activated to clean the surface of the lamp cover 2.

[0058] The regulating system includes:

[0059] A light intensity adjustment module, positioned between the movable base 3 and the lamp holder 5, is used to monitor the position of the movable base 3 and adjust the light intensity; and

[0060] The range adjustment module is located between the movable base 3 and the bulb 4, and is used to adjust the angle between the bulb 4 and the lamp base 5.

[0061] In one specific embodiment, the light intensity adjustment module includes a rotating wheel 22, a conductive head 24, a guide groove 25, and a resistor strip 26;

[0062] The rotating wheel 22 is movably mounted on the movable seat 3 and slides with the lamp holder 5. The guide groove 25 is mounted on the rotating wheel 22. The conductive head 24 is mounted on the movable seat 3 and slides with the guide groove 25. The resistor strip 26 is mounted in the guide groove 25 and is located on the moving path of the conductive head 24. The resistor strip 26, the conductive head 24 and the bulb 4 are electrically connected.

[0063] In another specific embodiment, the range adjustment module includes:

[0064] Piston 7 is movably disposed in the adjustment cavity formed inside the lamp holder 5 and the two are connected by an elastic element;

[0065] Adjustment seat 6 is movably disposed within lamp holder 5 and one end is connected to piston 7. The other end of adjustment seat 6 is movably connected to adjustment seat 6 via push rod 10.

[0066] An air cylinder 9 is installed inside the lamp holder 5, and its movable end is connected to the movable seat 3. The air cylinder 9 is connected to the adjustment chamber.

[0067] It should be noted that the elastic element can be a spring 8, a spring sheet, or an elastic steel plate structure. In this embodiment, the elastic element is preferably a spring 8, which is connected between the first piston 7 and the adjusting chamber. The specific model of the spring 8 can be selected according to the actual situation and is not specifically limited here.

[0068] In practical applications, mounting base 1 is fixed to the front of the subway car, and lamp holder 5 is fixedly installed on mounting base 1 through a locking structure. When the subway is traveling at high speed, the airflow impacts the surface of lamp cover 2, and the faster the subway travels, the greater the impact force of the airflow on the surface of lamp cover 2. Due to the impact of the airflow, lamp cover 2 and moving base 3 are displaced relative to lamp holder 5. On the one hand, this drives the rotating wheel 22 to move synchronously. On the other hand, under the action of frictional resistance between rotating wheel 22 and lamp holder 5, rotating wheel 22 is driven. At this time, conductive head 24 can change the resistance value of the circuit where bulb 4 is located according to the displacement distance of moving base 3 and the different contact positions on resistor strip 26. The faster the subway travels, the greater the impact force. The greater the luminous intensity of bulb 4, the more it can drive the air cylinder 9 to work while the moving seat 3 moves, squeezing the air in the air cylinder 9 into the adjustment chamber. This causes piston 7 to move along the adjustment chamber, which in turn moves the adjustment seat 6. Under the action of push rod 10, bulb 4 rotates along its hinge, thereby changing the angle between bulb 4 and lamp holder 5. This ensures that the illumination range of bulb 4 increases with the speed of the subway when it is running at high speed, thus ensuring the lighting environment of the subway when it is running in the tunnel. Furthermore, the movement of lamp cover 2 and moving seat 3 can drive the cleaning components to work synchronously, thereby cleaning the dust on the surface of lamp cover 2 without the need for manual cleaning by staff.

[0069] Please see Figure 1 as well as Figure 3 As another preferred embodiment of this application, the locking structure includes:

[0070] The limiting strip 20 is movably mounted on the lamp holder 5, and the mounting base 1 is formed with a limiting groove 23 that is adapted to the limiting strip 20;

[0071] Airbag 19, mounted on lamp holder 5 and connected to limiting strip 20; and

[0072] An inflation unit is installed on the lamp holder 5 and communicates with the airbag 19, and is used to control the size of the airbag 19.

[0073] In this embodiment, the inflation unit includes, for example:

[0074] Piston 18 is movably disposed in cavity 21 formed inside lamp holder 5 and the two are elastically connected, and cavity 21 is connected to airbag 19.

[0075] The handle 16 is movably mounted on the lamp holder 5 and movably connected to the piston; and

[0076] A locking bar 17 is provided on the rotating handle 16, and the lamp holder 5 is provided with a plurality of locking grooves, which are located on the moving path of the locking bar 17.

[0077] It should be noted that this embodiment is not limited to the inflation unit described above for inflating the airbag 19. A fan or air pump can also be used instead, but these will not be listed in this embodiment.

[0078] When the lamp holder 5 is installed in the mounting base 1, the lamp holder 5 can be inserted into the mounting base 1. By rotating the handle 16, the locking strip 17 can be rotated and disengaged from the locking groove. At this time, pressing the handle 16 will drive the second piston 18 to move along the cavity 21, thereby squeezing the air in the cavity 21 into the airbag 19. The increased volume of the airbag 19 can drive the limiting strip 20 to move towards the limiting groove 23, thereby fixing the mounting base 1 in the mounting base 1. Then, the locking strip 17 is inserted into the locking groove on the side of the lamp holder 5 near the cavity 21. When it is necessary to remove the lamp holder 5 from the mounting base 1 for maintenance of the bulb 4, the handle 16 can be rotated to make the locking strip 17 disengage from the locking groove. Under the action of elastic restoring force, the piston returns to its original position and the airbag 19 contracts, and the limiting strip 20 and the limiting groove 23 disengage, thereby facilitating the disassembly and installation of the lamp holder 5 and eliminating the traditional bolt-type fixing method.

[0079] Please see Figures 1-8 In another preferred embodiment of this application, the cleaning component includes:

[0080] The actuator, movably mounted on the movable base 3 and located outside the lampshade 2, is used to perform the action of cleaning dust from the surface of the lampshade 2; and

[0081] The drive module, located between the lamp holder 5 and the movable seat 3, is used to drive the execution structure to work.

[0082] In one specific embodiment, the execution structure includes a cleaning seat 11, a plurality of dust removal heads 12, and a connecting shaft 34;

[0083] The shape of the cleaning seat 11 is adapted to the shape of the lampshade 2. Several dust removal heads 12 are equidistantly arranged on the inner wall of the cleaning seat 11. The cleaning seat 11 is movably mounted on the movable seat 3 via the connecting shaft 34 and connected to the drive module.

[0084] In another specific embodiment, the driving module includes:

[0085] A hollow tube 15 is mounted on a movable seat 3. The hollow tube 15 is provided with an input hole 27 and an output hole 28. A one-way valve 29 is provided in both the input hole 27 and the output hole 28. The output hole 28 is connected to a cleaning seat 11. The cleaning seat 11 is movably mounted on the hollow tube 15 via a connecting shaft 34.

[0086] The extrusion plate 30 is movably disposed inside the hollow tube 15;

[0087] A rotating shaft 31 is movably disposed inside a hollow tube 15 and connected to an extrusion plate 30; the rotating shaft 31 is connected to a connecting shaft 34.

[0088] A threaded rod 32 is mounted on a rotating shaft 31, and a threaded sleeve 33 that threadedly engages with the threaded rod 32 is disposed inside the hollow tube 15; and

[0089] A transmission component is disposed between the lamp holder 5 and the rotating shaft 31. When the movable seat 3 moves relative to the lamp holder 5, the rotating shaft 31 is controlled to rotate through the transmission component.

[0090] It should be noted that the connecting shaft 34 is provided with a retaining strip 35, and the rotating shaft 31 is provided with a retaining groove 36 that is adapted to the retaining strip 35.

[0091] In addition, the transmission component includes a gear 13 and a rack 14. The gear 13 is movably mounted on the hollow tube 15 and connected to the rotating shaft 31. The rack 14 is mounted on the lamp holder 5 and meshes with the gear 13.

[0092] When the airflow impacts the lampshade 2, causing the lampshade 2 and the movable seat 3 to move relative to the lamp holder 5, it drives the gear 13 to move relative to the rack 14. Under the meshing action between the gear 13 and the rack 14, the gear 13 and the rotating shaft 31 can be rotated. At this time, under the threaded engagement between the threaded rod 32 and the threaded sleeve 33, the extrusion plate 30 can be moved along the hollow tube 15, thereby squeezing the air in the hollow tube 15 into the cleaning seat 11 through the output hole 28. Finally, the airflow is sprayed from the dust removal head 12 onto the surface of the lampshade 2, thereby removing the dust from the surface of the lampshade 2. At the same time, when the rotating shaft 31 rotates, under the engagement action between the locking strip 35 and the locking groove 36, the cleaning seat 11 can be rotated relative to the lampshade 2, thereby adjusting the position of the cleaning seat 11 and the dust removal head 12, achieving a thorough cleaning of the surface of the lampshade 2 without the need for manual periodic cleaning.

[0093] How this application works:

[0094] Mounting base 1 is fixed to the subway car head. When lamp holder 5 is installed in mounting base 1, lamp holder 5 can be inserted into mounting base 1. By rotating handle 16, locking strip 17 can be rotated and disengaged from locking groove. At this time, pressing handle 16 drives piston 18 to move along cavity 21, thereby squeezing air in cavity 21 into airbag 19. The increased volume of airbag 19 can drive limiting strip 20 to move towards limiting groove 23, thereby fixing mounting base 1 in mounting base 1. Then, locking strip 17 is inserted into locking groove on the side of lamp holder 5 near cavity 21. When it is necessary to remove lamp holder 5 from mounting base 1 for maintenance of bulb 4, rotating handle 16 can make locking strip 17 disengage from locking groove. Under the action of elastic restoring force, piston returns to its original position and airbag 19 contracts, limiting strip 20 and limiting groove 23 disengage, thus facilitating the disassembly and installation of lamp holder 5 and eliminating the traditional bolt fixing method. When the subway travels at high speed, the airflow impacts the surface of the lampshade 2. The faster the subway travels, the greater the impact force of the airflow on the surface of the lampshade 2. Due to the impact of the airflow, the lampshade 2 and the moving seat 3 are displaced relative to the lamp holder 5. This causes the rotating wheel 22 to move synchronously. Under the frictional resistance between the rotating wheel 22 and the lamp holder 5, the rotating wheel 22 rotates. At this time, the conductive head 24 can change the resistance value of the circuit where the bulb 4 is located according to the displacement distance of the moving seat 3 and the different contact positions on the resistor strip 26. This makes the light intensity of the bulb 4 greater the faster the subway travels. At the same time as the moving seat 3 moves, it can drive the air cylinder 9 to work, squeezing the air in the air cylinder 9 into the adjustment chamber. This causes the first piston 7 to move along the adjustment chamber, thereby causing the adjustment seat 6 to move. Under the action of the push rod 10, the bulb 4 rotates along its hinge, thereby changing the angle between the bulb 4 and the lamp holder 5. This ensures that the illumination range of the bulb 4 is maintained when the subway is traveling at high speed. The enclosure increases with the speed of the subway to ensure the lighting environment when the subway is running in the tunnel. When the airflow impacts the lamp cover 2, the lamp cover 2 and the moving seat 3 move relative to the lamp holder 5, which drives the gear 13 to move relative to the rack 14. Under the meshing action between the gear 13 and the rack 14, the gear 13 and the rotating shaft 31 can be rotated. At this time, under the threaded engagement between the threaded rod 32 and the threaded sleeve 33, the extrusion plate 30 can be moved along the hollow tube 15, thereby squeezing the air in the hollow tube 15 into the cleaning seat 11 through the output hole 28. Finally, the airflow is sprayed from the dust removal head 12 onto the surface of the lamp cover 2, thereby removing the dust from the surface of the lamp cover 2. At the same time, when the rotating shaft 31 rotates, under the engagement action between the locking strip 35 and the locking groove 36, the cleaning seat 11 can be rotated relative to the lamp cover 2, thereby adjusting the position of the cleaning seat 11 and the dust removal head 12, realizing a thorough cleaning of the surface of the lamp cover 2 without the need for manual periodic cleaning.
