[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1-4 shown, the present invention provides a technical solution: an LED lighting fixture for adjusting color temperature, including an aluminum top cover 1. A full-aluminum lamp cover 2 is inserted and installed at the bottom of the aluminum top cover 1. A diffusion plate 3, a light guide plate 4, and a reflective paper 5 are sequentially installed from bottom to top in the full-aluminum lamp cover 2. Both the aluminum top cover 1 and the full-aluminum lamp cover 2 are disc-shaped. The diffusion plate 3, the light guide plate 4, and the reflective paper 5 are all circular. The diffusion plate 3 and the light guide plate 4 have the same size. The diameter of the reflective paper 5 is larger than the diameter of the light guide plate 4. A circle of LED light strips 6 is installed on the inner wall of the full-aluminum lamp cover 2 corresponding to the position of the light guide plate 4;

[0022] Above the reflective paper 5, there is a polyurethane-aluminum foil heat insulation plate 7. One side of the polyurethane-aluminum foil heat insulation plate 7 corresponding to the controller 8 is an aluminum foil layer, which reflects heat radiation and isolates heat. Above the reflective paper 5, there is a pressing plate 13. A thickened cushion block 14 is arranged between the pressing plate 13 and the polyurethane-aluminum foil heat insulation plate 7 to increase the distance between the LED light strip 6 and the controller 8, and at the same time press the internal components tightly to prevent the components from loosening due to vibration during transportation;

[0023] The controller 8 is installed in the installation groove at the top of the inner wall of the aluminum top cover 1. A conductive paste 16 is applied between the controller 8 and the aluminum top cover 1 to improve the heat conduction and heat dissipation effect. Buffer cushion blocks 15 are arranged between the controller 8 and the polyurethane-aluminum foil heat insulation plate 7 and between the controller 8 and the inner side wall of the installation groove corresponding to the aluminum top cover 1 at the corresponding position to press the controller 8 tightly to prevent loosening due to vibration during transportation. And at the position of the color temperature adjustment slider 9 on the controller 8 on the top of the aluminum top cover 1, there is a sliding groove 10. Connection ears 11 are arranged on both sides of the aluminum top cover 1, and a lamp fixture fixing spring clip 12 is installed on the connection ears 11.

[0024] Working principle:

[0025] After power-on, manually adjust the default color temperature when turning on the light by moving the color temperature adjustment slider 9 back and forth. Turn off the lamp power switch, fold up the lamp fixing spring clip 12 upward, and snap the aluminum top cover 1 of the lamp into the circular installation groove opened on the ceiling. The lamp fixing spring clip 12 automatically flips downward and presses on the ceiling to complete the installation of the lamp. After power-on, the bright light emitted by the LED strip 6 is evenly dispersed by the light guide plate 4 and refracted upward and downward. Through the upper reflective paper 5, all the light passes through the diffusion plate 3 and shines downward to achieve the lighting function. During use, both the LED strip 6 and the controller 8 generate heat. The all-aluminum lamp shade 2 and the aluminum top cover 1 have good heat conduction effects, which is beneficial to the heat dissipation of the LED strip 6 and the controller 8. The polyurethane-aluminum foil heat insulation plate 7 separates the controller 8 from the LED strip 6, isolating the heat generated by the two during long-term use and preventing mutual influence from accelerating the aging of each other.
