[0003] Conventional direct-down lighting downlights account for a large proportion in the market. Most of them use the method of adjusting color temperature by dip switches. However, the dip switches are basically set at the rear of the lamp body and hidden in the ceiling. To adjust the color temperature, the whole lamp needs to be removed from the ceiling before adjustment. Since the lamp is installed upside down on the ceiling, it is troublesome to remove, which increases the difficulty for customers to adjust the color temperature. Summary of the Invention

A flexible light source board 6 is connected to the inner wall of the front frame 8. The flexible light source board 6 includes a number of alternately arranged low-color-temperature LED beads and high-color-temperature LED beads. The color temperature of the low-color-temperature LED beads is selected as 3000K, and the color temperature of the high-color-temperature LED beads is selected as 5000K. A diffusion plate 5, a light guide plate 10 and a reflective paper 4 are sequentially arranged in the front frame 8 from bottom to top. The diffusion plate 5, the light guide plate 10 and the reflective paper 4 constitute an optical component. The top end inside the rear cover 2 is connected with a push switch 12; The push switch 12 includes a switch PCB board 13. A connection circuit is provided on the switch PCB board 13 for realizing the electrical connection between the switch body 14, the driver and the flexible light source board 6. The middle position of the switch PCB board 13 is connected with a switch body 14. The pressing end of the switch body 14 faces downward. The switch body 14 is selected as the TD-06XG-250H6-L8.5 type of Lito Electronics.

[0035] By adopting the above technical solutions, the present invention triggers the switch body 14 by pressing the optical component upward to realize the adjustment of the color temperature, without disassembling the whole lamp, making the adjustment of the color temperature simpler and more convenient; after the adjustment is completed, release the optical component, and under the action of gravity and the restoring force of the switch body 14, the optical component is reset downward.

[0036] Specifically, two symmetric buckles 21 are provided on the rear cover 2. The height of the buckles 21 is slightly less than the height of the pressing end of the switch body 14 in the non-loaded state.

[0037] By adopting the above technical solutions, the buckles 21 realize the limit connection between the switch PCB board 13 and the rear cover 2, and at the same time can also limit the stroke of pressing the optical component, avoiding damage to the switch body 14 caused by excessive pressing and the deviation of the optical component during reset.

[0038] Specifically, a waterproof gasket 9 is provided between the diffusion plate 5 and the front frame 8.

[0039] By adopting the above technical solutions, it is used to realize the sealing and waterproofing of the front frame 8.

[0040] Specifically, a method for realizing a downlight for realizing color temperature adjustment by front pressing includes the following steps:

[0041] (1). The switch PCB board 13 is connected to the rear cover 2 through two symmetrical buckles 21. The pressing end of the switch body 14 is welded downward on the switch PCB board 13. An optical component that can move upward is provided below the switch body 14 inside the housing;

[0042] (2). Press the optical component upward. The optical component moves upward, pushing the switch body 14 on the push switch 12 to act, realizing the adjustment of the color temperature;

[0045] The difference between this embodiment and Embodiment 1 is that specifically, the optical component further includes an EVA cotton pad 11 arranged above the reflective paper 4. The elastic component is a spring 3. The rear cover 2 and the EVA cotton pad 11 are connected by four springs 3. The spring 3 is a compression spring. In the natural state, the deformation percentage of the spring 3 is 30%.

[0046] By adopting the above technical solution, the elastic restoring force of the spring 3 acts on the EVA cotton pad 11, pressing the diffusion plate 5 tightly on the waterproof gasket 9, ensuring the sealing and waterproof effect of the front frame 8, and after adjusting the color temperature, making the optical component reset downward.

[0047] Specifically, the rear cover 2 is provided with connection posts 22 corresponding to the springs 3, and the springs 3 are in interference fit with the connection posts 22.

[0048] By adopting the above technical solution, the installation of the spring 3 is realized.

[0049] Embodiment 3

The elastic block 23 and the rear cover 2 are an integrally injection-molded structure, and the elastic block 23 is arranged in an arc shape.

[0051] By adopting the above technical solution, when pressing the optical component, the elastic block 23 deforms, and after adjusting the color temperature, the optical component is reset downward by using the deformation restoring force of the elastic block 23.

[0052] Embodiment 4

[0053] Please refer to Figures 5 - 6 , the difference between this embodiment and Embodiment 1 is that specifically, there are two switch bodies 14, and the two switch bodies 14 are symmetrically installed at both ends of the lower surface of the switch PCB board 13.

[0054] By adopting the above technical solution, one switch body 14 is used to adjust the color temperature, and the other switch body 14 can be used to adjust other functions such as power, increasing the functionality of the downlight.

[0055] Specifically, a support post 24 is provided at the center position of the rear cover 2. The height of the support post 24 is equal to the height of the pressing end of the switch body 14 in the non-loaded state. A through hole 15 corresponding to the support post 24 is provided at the center position of the switch PCB board 13.

[0056] By adopting the above technical solution, the center position of the optical component is limited by the support post 24, so that the optical component can only move upward when stressed on both sides, avoiding the situation where the two switch bodies 14 are triggered simultaneously.

[0057] In summary, in the present invention, the switch body 14 is triggered by pressing the optical component upward to realize the adjustment of the color temperature, without the need to disassemble the whole lamp, making the adjustment of the color temperature simpler and more convenient; two symmetric buckles 21 are provided on the rear cover 2 of the present invention to realize the limit connection between the switch PCB board 13 and the rear cover 2, and at the same time, the stroke of pressing the optical component can be limited to avoid damage to the switch body 14 caused by excessive pressing and the deviation of the optical component during reset; in the present invention, the rear cover 2 and the EVA cotton pad 11 are connected by four springs 3, and the elastic restoring force of the springs 3 acts on the EVA cotton pad 11, pressing the diffusion plate 5 tightly on the waterproof gasket 9 to ensure the sealing and waterproof effect of the front frame 8 and make the optical component reset downward after adjusting the color temperature; in the present invention, the elastic deformation restoring force of the elastic block 23 can also be used to make the optical component reset downward; two switch bodies 14 are provided in the present invention, one switch body 14 is used to adjust the color temperature, and the other switch body 14 can be used to adjust other functions such as power, increasing the functionality of the downlight; when two switch bodies 14 are provided in the present invention, the center position of the optical component is limited by the support post 24, so that the optical component can only move upward when stressed on both sides, avoiding the situation where the two switch bodies 14 are triggered simultaneously.
