The power line 2 is connected to the power supply, and the terminal connection 3 is connected to the power supply line of the lamp body. The power conversion circuit board 8 includes a rectifier circuit, a filter circuit, a transformer, and a voltage stabilizing circuit. The rectifier circuit includes a rectifier bridge or a single rectifier diode, which is used to convert the positive and negative half-cycle waveforms of the AC power supply into a unidirectional DC voltage. The filter circuit includes capacitor filtering and inductor filtering, which can effectively smooth the output voltage waveform. The transformer is used to step down or step up to match the working voltage requirements of the LED. The voltage stabilizing circuit includes a voltage stabilizing chip or a voltage stabilizing diode, which can effectively maintain the stability of the output voltage within a certain range.

[0022] The edge of the top of the opening 4 is provided with an eave 401, and the bottom of the sealing cover 5 is provided with an eave 501 which fits with the eave 401. After the driver housing 1 and the sealing cover 5 are fastened together, the sealing surface composed of the eave 401 and the eave 501 can form a larger contact area, and the connection between the sealing cover 5 and the driver housing 1 is made tighter, which can prevent the intrusion of external harmful substances such as dust and water vapor, and protect the internal circuits and components from being affected by the external environment.

[0023] The four-point connection piece includes a positioning post 502 fixed at the corner position of the bottom end of the sealing cover 5, and a calibration hole 102 which is concentric with the positioning post 502 and is provided at the top end of the driver housing 1. When the staff fully encapsulates the sealing cover 5 in the opening 4 at the top end of the driver housing 1, the sealing cover 5 and the driver housing 1 are preliminarily connected by using the calibration hole 102 and the positioning post 502 until the positioning post 502 is plugged into place. The connection design of the calibration hole 102 and the positioning post 502 can ensure that the sealing cover 5 can be accurately positioned on the driver housing 1 during the installation process, avoiding displacement and misalignment during the installation process;

[0024] The double-column connector 9 includes a sliding tongue 901 slidably mounted on one side of the inner side of the rectangular sink 7, and two pins 902 fixed on the outer wall of one side of the sliding tongue 901. The front and rear ends of the rectangular block 6 are both provided with limiting holes 601 mutually plugged with the pins 902.

[0025] The bidirectional elastic push-up structure 12 includes a rotating shaft 1201 rotatably mounted inside the rectangular trough 11, and an I-shaped swing frame 1202 fixed on the surface of the rotating shaft 1201. Trapezoidal slides 1204 are slidably mounted on both sides of the rectangular trough 11. Reset springs 1205 are fixed on the front and rear inner walls of the rectangular trough 11. The top of the reset spring 1205 extends to the inside of the trapezoidal slide 1204. One end of the sliding tongue 901 extends to the inside of the rectangular trough 11 and is fixedly connected to one end of the trapezoidal slide 1204. The top of the rotating shaft 1201 passes through the outside of the driver housing 1 and is fixedly connected to the bottom end of the knob 10. When the square block 6 is inserted into the rectangular sink groove 7, the user releases the knob 10, and the reset spring 1205 gradually recovers from the compressed state to the initial state, that is, the reset spring 1205 makes the trapezoidal slide 1204 and the sliding tongue 901 move toward the direction of the rotating shaft 1201, and the I-shaped swing frame 1202 deflects. At this time, the pin 902 is inserted into the limiting hole 601 of the square block 6, so that the square block 6 is fixed in the rectangular sink groove 7. Through the bidirectional elastic pushing structure 12, the double-column connector 9 can apply a uniform force to the square block 6 to prevent the sealing cover 5 from loosening or falling off due to vibration or external impact during the operation of the lamp body and the driver;

[0026] Rubber rollers 1203 are rotatably installed at both ends of the I-shaped swing frame 1202. The two ends of the I-shaped swing frame 1202 produce rolling friction through the rubber rollers 1203 and the outer wall of one side of the trapezoidal slide 1204, so that the I-shaped swing frame 1202 can stably push the trapezoidal slide 1204 to slide through the rubber rollers 1203.

[0027] When the embodiment of the present application is in use, first, when the staff wants to remove the sealing cover 5 and inspect and maintain the power conversion circuit board 8 and other electrical components inside the driver housing 1, the staff manually rotates the knob 10, so that the knob 10 drives the bidirectional elastic push structure 12 to move. At this time, the bidirectional elastic push structure 12 can drive the two double-column connectors 9 to move away from each other until the double-column connectors 9 are withdrawn to the outside of the square block 6. At this time, the square block 6 will not be affected when it moves in the Z-axis direction, and then the staff lifts the sealing cover 5 upwards, so that the four-point connection parts at the bottom of the sealing cover 5 are connected with the driver housing 1. Separation, the rectangular block 6 is separated from the rectangular sink 7 until the opening 4 and the sealing cover 5 are completely separated. At this time, the opening 4 is in an open state, and the staff can inspect, maintain and debug the power conversion circuit board 8 and electrical components in the driver housing 1. Through the arrangement of the two-way elastic pushing structure 12, the double-column connector 9, the rectangular block 6 and other components, the user can quickly and conveniently remove the sealing cover 5. No professional tools and operations are required, which lowers the threshold for driver maintenance, allowing staff and users to quickly troubleshoot, replace components or perform daily cleaning, thereby reducing maintenance time and cost.
