DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a color temperature adjustment circuit board, including a lamp housing 1, a lampshade 101 is detachably connected to the top of the lamp housing 1, an LED lamp bead is installed on the top of the lampshade 101, and the left and right side ends inside the lamp housing 1 are fixedly connected to a fixing plate 2, a circuit board 4 is installed between the top of each fixing plate 2, and a color temperature adjustment component is provided at the top of the circuit board 4. The color temperature adjustment component includes a color temperature adjustment controller 401 and a driver 402, the color temperature adjustment controller 401 is connected to the top of the circuit board 4 through a wire, the driver 402 is connected to the top of the circuit board 4 through a wire, and the LED lamp bead is connected to the circuit board 4 through a wire. When the power terminal at the bottom end of the lamp housing 1 is powered, the color temperature adjustment function of the LED lamp bead can be realized through the color temperature adjustment component provided on the top of the circuit board 4, so that the circuit board 4 can realize the color temperature adjustment function.

[0021] Furthermore, each fixing plate 2 is provided with a plurality of mounting grooves 201 inside, a notch 202 is provided at the top of each mounting groove 201, a rebound component is provided inside each mounting groove 201, and a fixing component is provided between the tops of two adjacent rebound components. Through the cooperation of the rebound component and the fixing component, the circuit board 4 and the color temperature adjustment component can be easily disassembled.

[0022] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the rebound component includes a round rod 3, which is fixedly connected between the inner side ends of the mounting groove 201, the outer end of the round rod 3 is sleeved with a spring 301, and the outer end of the round rod 3 is sleeved with a sleeve plate 302, the top of the sleeve plate 302 is inserted into the inner side of the slot 202 and extends to the top of the fixed plate 2, and the fixing component includes a clamping plate 303, which is fixedly connected to the top of the sleeve plate 302, and the side end of the clamping plate 303 is fixedly connected with a pulling plate 3031. During implementation, by pulling the pulling plates 3031 at the two side ends, the two clamping plates 303 are driven to open and move outward, and at this time, the sleeve plate 302 can be driven to press the spring 301 to shrink, and at this time, after the two clamping plates 303 are opened, the circuit board 4 can be easily disassembled.

[0023] As an implementation method in this embodiment, Figure 4 As shown, two sets of limit frames 304 are fixedly connected to the top of the clamping plate 303, and the appearance of each limit frame 304 is L-shaped, which is convenient for installing the color temperature controller 401 and the driver 402. The top of the clamping plate 303 is provided with a side groove 305, which can facilitate the placement of the wire, thereby limiting the position of the circuit board 4, so that the circuit board 4 is not easy to move forward and backward between the clamping plates 303.

[0024] During implementation, the two wires at the top of the circuit board 4 are taken out from the side grooves 305 at both ends. At this time, the color temperature controller 401 and the driver 402 can be taken out from the inner side of the limit frame 304 by pulling the wires, thereby facilitating the disassembly of the color temperature controller 401 and the driver 402.

[0025] Working principle: by pulling the pull plates 3031 at the two side ends, the two clamping plates 303 are driven to open and move outward, and at this time, the sleeve plate 302 can be driven to press the spring 301 to shrink. At this time, after the two clamping plates 303 are opened, the circuit board 4 can be easily disassembled. At this time, the two wires at the top of the circuit board 4 are taken out from the side grooves 305 at both ends. At this time, after pulling the wires, the color temperature controller 401 and the driver 402 can be taken out from the inside of the limit frame 304, so as to facilitate the disassembly of the circuit board 4, the color temperature controller 401 and the driver 402.

[0026] When it is necessary to install the circuit board 4, by pulling the pull plates 3031 at the two side ends, the two clamping plates 303 are driven to open and move outward, and the sleeve plate 302 can be driven to press the spring 301 to shrink. At this time, after the two clamping plates 303 are opened, it is convenient to install the circuit board 4. After the pull plates 3031 at the two side ends are released, the spring 301 rebounds against the sleeve plate 302 and drives the clamping plates 303 to clamp and fix the two ends of the circuit board 4, thereby completing the installation of the circuit board 4. At this time, the wires at both ends are placed in the side grooves 305. Then, because the wires are long enough, the color temperature controller 401 and the driver 402 can be pushed and placed in the limit frame 304, so that the device can facilitate the installation of the circuit board 4 and the installation of the color temperature controller 401 and the driver 402 at the same time. The disassembly and installation methods are simple and fast.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
