[0045] The mounting base plate 1 is fixedly connected with a slide rail 103 on the left and right sides of the bottom end surface, and T-shaped slide grooves 1031 are formed in the opposite surfaces of the two slide rails 103.

[0046] The lampshade 3 is internally provided with a BOPET light-reflecting film 303, which can enhance light reflection and improve lighting effect and visual comfort. A light sensor 304 is mounted on the upper side of the inside of the lampshade 3 and is used to sense whether the LED energy-saving lamp tube 301 is turned on. The light sensor 304 penetrates through the BOPET light-reflecting film 303.

[0047] The worm 507 is fixedly mounted on the rotating shaft of the micro motor 506, and the worm wheel 508 is fixedly mounted outside the threaded cylinder 504 and engages with the worm 507. The micro motor 506 is an encoder motor. The micro motor 506 with an encoder can drive the threaded cylinder 504 to rotate to a specified number of turns, thereby improving the rotation accuracy of the light-shielding protective cover 402 when it is opened and closed.

[0048] The trapezoidal slide groove 5011 is formed in the bottom end surface of the sliding plate 501, and the trapezoidal slide bar 5021 fixedly connected to the upper end surface of the sliding bar 502 is in sliding connection with the trapezoidal slide groove 5011, so that the sliding bar 502 can be effectively guided when it slides.

[0049] The angle adjusting assembly 7 includes an adjusting worm 701 and an adjusting worm wheel 703. The adjusting worm 701 is rotatably connected to the right side of the bottom end surface of the connecting lamp holder 2, and the adjusting worm wheel 703 is fixedly mounted at the right end of the right rotating rod 302. The adjusting worm wheel 703 engages with the adjusting worm 701, and the adjusting worm 701 is provided with a rotating hand wheel 702 at the front end. According to the actual situation, the irradiation angle of the LED energy-saving lamp tube 301 can be adjusted by rotating the rotating hand wheel 702, which drives the adjusting worm 701, the adjusting worm wheel 703, the rotating rod 302, the lampshade 3, and the LED energy-saving lamp tube 301 to rotate, so that the irradiation angle of the LED energy-saving lamp tube 301 is adjusted, thereby adapting to the lighting needs of different internal equipment of the electromechanical cabinet 8.

[0050] The unwinding spiral angle of the adjusting worm 701 is smaller than the friction angle of the contact with the adjusting worm wheel 703, so that the adjusting worm 701 and the adjusting worm wheel 703 can realize effective self-locking, thereby improving the stability of the LED energy-saving lamp tube 301 when it is used after angle adjustment.

[0051] When the LED energy-saving lamp tube 301 is in the light-emitting state, the light sensor 304 senses the bright light, and the controller 205 controls the micro motor 506 to rotate in the positive direction, and at this time, the light shielding protective cover 402 is in the open state.

[0052] The travel switch 6 is installed on the upper left side of the electromechanical cabinet 8, and the travel switch 6 is a roller type travel switch 6, and the travel switch 6 is electrically connected with the LED energy-saving lamp tube 301, when the cabinet door on the electromechanical cabinet 8 is in the closed state, the roller on the travel switch 6 is in close contact with the rear end face of the cabinet door; through the setting of the travel switch 6, the LED energy-saving lamp tube 301 can be turned on immediately after the cabinet door is opened, and the convenience when the electromechanical cabinet 8 is maintained, maintained and operated is improved.

[0053] In the embodiment two, on the basis of the embodiment one, as shown in the figure, Figures 1 to 5 Two rectangular slide cavities 201 are symmetrically arranged on the front end face of the connecting lamp holder 2, three guide rods 202 are fixedly connected in each rectangular slide cavity 201, springs are sleeved on the outer sides of the guide rods 202, a sliding plate 203 is slidably connected in each rectangular slide cavity 201 through the guide rods 202, and a plug-in column 204 is fixedly connected to the back side of the opposite face of each sliding plate 203; a controller 205 is fixedly installed on the bottom left side of the connecting lamp holder 2, and a light sensor 304 and a micro motor 506 are electrically connected with the controller 205; a T-shaped sliding block 206 is fixedly connected to the left and right sides of the connecting lamp holder 2; through the cooperation of the sliding plate 203, the plug-in column 204, the plug-in block 104 and the plug-in hole 1041, the connecting lamp holder 2 and the mounting base plate 1 can be quickly separated, the tool-free disassembly and assembly design avoids the tedious operation of loosening the screws one by one in the traditional screw fixing mode, shortens the disassembly and assembly time to less than 5 seconds, significantly improves the maintenance efficiency, and at the same time, the precise cooperation of the plug-in structure ensures the accurate positioning during installation, retains the reliability of the traditional screw fixing, and realizes the convenience of quick maintenance.

[0054] When the connecting lamp holder 2 and the mounting base plate 1 are in the installed state, the two T-shaped sliding blocks 206 are slidably connected with the two T-shaped sliding grooves 1031 respectively, and the two plug-in columns 204 are plug-in connected with the two plug-in holes 1041 respectively.

[0055] The working principle of the embodiment is as follows: during installation, the mounting block 101 on the mounting base plate 1 is fixedly connected to the top end face in the electromechanical cabinet 8 through the fixing screws 102, and then the connecting lamp holder 2 is installed at the bottom of the mounting base plate 1, at this time, the two T-shaped sliding blocks 206 are slidably connected with the two T-shaped sliding grooves 1031 respectively, and the two plug-in columns 204 are plug-in connected with the two plug-in holes 1041 respectively, so that the lighting device is effectively fixed in the electromechanical cabinet 8.

[0056] After installation, close the cabinet door on the electromechanical cabinet 8. The roller on the limit switch 6 is in close contact with the rear end of the cabinet door. At this time, the limit switch 6 turns off the LED energy-saving lamp 301. After the light sensor 304 no longer detects light, it transmits this signal to the controller 205. The controller 205 then controls the micro motor 506 to rotate in reverse, thereby rotating the worm 507, worm wheel 508, and threaded cylinder 504 a specified number of times. Then, the screw 505 is driven to move the sliding bar 502 backward in a straight line under the action of the thread. The sliding bar 502 drives the disc 403 to rotate counterclockwise (viewed from left to right), thereby rotating the rotating shaft 401 and the light-shielding protective cover 402 counterclockwise. Finally, the light-shielding protective cover 402 is closed. The light-shielding protective cover 402 in the closed state can effectively protect the LED energy-saving lamp 301, prevent dust from falling on the LED energy-saving lamp 301, and improve the service life of the LED energy-saving lamp 301.

[0057] When the cabinet door is opened in a dark environment, the roller on the limit switch 6 separates from the rear end of the cabinet door. At this time, the limit switch 6 quickly turns on the LED energy-saving lamp 301. After the light sensor 304 detects the light, it transmits this signal to the controller 205. The controller 205 then controls the shaft of the micro motor 506 to rotate forward, thereby rotating the worm gear 507, worm wheel 508, and threaded cylinder 504 a specified number of times. Then, the screw 505 is driven to move forward linearly along the sliding strip 502 and the driving plate 509 under the action of the thread. The forward-moving drive plate 509 drives the drive column 404 to rotate clockwise, thereby driving the disc 403 to rotate slowly clockwise (viewed from left to right), which in turn drives the rotating shaft 401 and the light-shielding protective cover 402 to rotate slowly clockwise, thus causing the light-shielding protective cover 402 to open slowly. This gradual opening process is designed to take 3-5 seconds, so that the initial light intensity gradually transitions from 0 lx to the working illuminance of 500-800 lx, which conforms to the physiological characteristics of dark adaptation of the human eye, thus allowing the human eye a certain amount of adaptation time.

[0058] When the lighting device needs to be disassembled for maintenance, the maintenance personnel only need to manually move the front ends of the two sliding plates 203 simultaneously in opposite directions. This will move the two plug-in posts 204 simultaneously in opposite directions, eventually causing the two plug-in posts 204 to be pulled out from the two plug-in holes 1041 respectively. This will cause the connecting lamp holder 2 to lose its fixing function at the bottom of the mounting base plate 1. Then, the connecting lamp holder 2 can be slid forward and removed. This eliminates the need to loosen and remove the fixing screws 102 one by one during disassembly and maintenance, making the operation simple and efficient.
