The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 5 This is a circuit diagram of a novel ceiling light power control circuit according to this utility model.

[0022] This utility model provides a novel ceiling light structure, including a ceiling light body 101, a lampshade 102, a push rod 104, an auxiliary rod 105, a locking rod 106, a sliding rod 107, a mounting ring 108, a spring 109, a connecting block 110, a connecting rod 111, a frame 112, a support rod 113, a sliding base 114, and a mounting block 115. The aforementioned solution solves the problem that when repairing and replacing the LED aluminum substrate, the lampshade 102 needs to be rotated multiple times before it can be removed, and after the repair is completed, the lampshade 102 needs to be rotated in the opposite direction for installation. This is easy to damage after repeated use, affecting its use.

[0023] In this specific embodiment, the lampshade 102 has two locking holes 103. The lampshade 102 is slidably connected to the ceiling light body 101 and is located at one end of the ceiling light body 101. The push rod 104, the moving component, the support frame, the auxiliary rod 105, and the locking rod 106 are respectively disposed on the ceiling light body 101. The moving component is fixedly connected to the push rod 104. The connecting component is rotatably connected to the moving component and the sliding structure, and is located at one end of the moving component and the sliding structure. The support frame is rotatably connected to the connecting component and is located at one end of the connecting component. The sliding structure is slidably connected to the auxiliary rod 105 and is located at one end of the auxiliary rod 105. The locking rod 106 is fixedly connected to the sliding structure and is located on one side of the sliding structure. The locking rod 106 cooperates with the corresponding lock hole 103. The ceiling light body 101 is provided by the prior art. When maintenance is required, pressing the two pressing rods 104 will cause each pressing rod 104 to drive the moving component and the sliding structure. The component moves, and the moving component drives the connecting part to rotate around the support frame as a fulcrum. The connecting part drives the sliding structure to move on the auxiliary rod 105. The auxiliary rod 105 drives the locking rod 106 to move out of the locking hole 103, so that the lampshade 102 can be removed for maintenance. After maintenance, press the two push rods 104 to put the lampshade 102 into the ceiling light body 101. Then release the two push rods 104. At this time, the two locking rods 106 are respectively inserted into the two locking holes 103, so that the lampshade 102 can be fixed on the ceiling light body 101, thereby facilitating the maintenance of the ceiling light body 101.

[0024] The movable component includes a slide rod 107, a mounting ring 108, and a spring 109. The mounting ring 108 is fixedly connected to the slide rod 107 and is located at one end of the slide rod 107. The spring 109 is fixedly connected to the slide rod 107 and is located on one side of the slide rod 107. The slide rod 107 drives the mounting ring 108 to move while simultaneously compressing the spring 109.

[0025] Secondly, the connecting component includes a connecting block 110 and two connecting rods 111. The two connecting rods 111 are fixedly connected to the connecting block 110 and are symmetrically arranged at one end of the connecting block 110. The two connecting rods 111 are mounted on the connecting block 110.

[0026] Meanwhile, the support frame includes a frame body 112 and a support rod 113. The support rod 113 is fixedly connected to the frame body 112 and is located at one end of the frame body 112. The support rod 113 is installed on the frame body 112.

[0027] In addition, the sliding structure includes a slide block 114 and a mounting block 115. The mounting block 115 is fixedly connected to the slide block 114 and is located at one end of the slide block 114. The mounting block 115 is mounted on the slide block 114.

[0028] Using the novel ceiling light structure of this embodiment, when maintenance is required, pressing the two push rods 104 causes each push rod 104 to move the slide rod 107, which in turn moves the mounting ring 108, simultaneously compressing the spring 109. The mounting ring 108, through the corresponding connecting rod 111, causes the connecting block 110 to rotate around the support rod 113. The connecting block 110, through the corresponding connecting rod 111, causes the slide block 114 to move on the auxiliary rod 105. The slide block 114 moves along the mounting block 115, causing the locking rod 106 to move out of the corresponding locking hole 103, allowing the lampshade 102 to be removed for maintenance. After maintenance, the two push rods 104 are pressed again to place the lampshade 102 into the ceiling light body 101. Then, the two push rods 104 are released, and the two locking rods 106 are inserted into the two locking holes 103 respectively, thus fixing the lampshade 102 onto the ceiling light body 101, thereby facilitating maintenance of the ceiling light body 101.

[0029] This utility model also provides a novel ceiling light power control circuit, applied in the novel ceiling light structure described above. The novel ceiling light power control circuit includes a power supply terminal, transistors Q1 and Q2, light-emitting diodes LED1 and LED2, resistors R1 and R2, and capacitors C1 and C2. Transistor Q1 is connected to the power supply terminal by a wire, transistor Q2 is connected to the power supply terminal by a wire, capacitors C1 and C2 are electrically connected to both transistors Q1 and Q2, resistor R1 is connected to capacitor C1 by a wire, resistor R2 is connected to capacitor C2 by a wire, LED1 is connected to resistor R1 by a wire, and LED2 is connected to resistor R2 by a wire.
