[0004] For example, a Chinese utility model patent with the authorization announcement number CN 214147614 U discloses a dual-switch downlight for indoor lighting, including a main housing, a light-emitting component arranged in the main housing, a rear housing of the lamp body arranged on the top of the main housing, and a driving component arranged on the rear housing of the lamp body and electrically connected to the light-emitting component, a push adjustment switch electrically connected to the driving component is also arranged on the rear housing of the lamp body, a touch adjustment switch electrically connected to the driving component is also arranged on the light-emitting surface of the main housing, and a wiring channel is also arranged on the side of the main housing.

Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a downlight which can still adjust the color temperature after installation and does not affect the appearance of the lamp body in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a downlight, comprising an outer shell, a light source panel and a diffusion panel, the outer shell having a downward opening, the light source panel and the diffusion panel are both horizontally arranged inside the outer shell shell, the diffusion panel is located below the light source panel, and is characterized in that: a color temperature adjustment switch for adjusting the color temperature of the light emitted by the light source panel is arranged on one side of the light source panel close to the diffusion panel, a pressing transmission member is arranged between the color temperature adjustment switch and the diffusion panel, and when the diffusion panel is pressed from bottom to top, the diffusion panel pushes the pressing transmission member upward, so that the pressing transmission member presses the color temperature adjustment switch, and then the color temperature adjustment switch adjusts the color temperature of the light emitted by the light source panel.

[0007] In order to facilitate the pressing transmission member to accurately transmit the slight deformation of the diffusion plate to the color temperature adjustment switch, the color temperature adjustment switch is a touch switch, which includes a switch body and a button arranged below the switch body, and the pressing transmission member can press the button. The button is arranged below the switch body, which also reduces the distance between the diffusion plate and the color temperature adjustment switch, which is conducive to transmission.

[0008] In order to make the push transmission member accurately act on the button, the push transmission member is arranged along the vertical direction, and the upper end of the push transmission member is provided with an accommodating groove with an opening facing upward, and the button is accommodated in the accommodating groove. The button is accommodated in the accommodating groove to position the push transmission member, so that the push transmission member can be vertically arranged between the color temperature adjustment switch and the diffusion plate without the aid of other structures.

[0009] In other embodiments, the upper end of the push-button transmission member may also be fixedly connected to the button, such as by bonding.

[0010] Preferably, the accommodating groove includes a large groove and a small groove that are interconnected, the small groove is located at the center below the large groove, the switch body is accommodated in the large groove, and the button is accommodated in the small groove; the distance between the lower end surface of the button and the bottom wall of the small groove is smaller than the distance between the lower end surface of the switch body and the bottom wall of the large groove. The distance between the lower end surface of the switch body and the bottom wall of the large groove can make way for the pressing transmission member to press the button upward.

[0011] In order to reduce the volume of the pressing transmission part and thus reduce the influence of the pressing transmission part on light transmission, the pressing transmission part is composed of a large diameter section, a middle diameter section and a small diameter section from top to bottom, the large groove is located in the large diameter section, the small groove is located in the middle diameter section, and the outer diameter of the small diameter section gradually decreases from top to bottom.

[0012] In order to prevent the push transmission member from shifting in the vertical direction, the inner side wall of the small groove is in contact with the button, and the inner side wall of the large groove is in contact with the switch body. The tight contact between the small groove and the button, and the large groove and the switch body in the horizontal direction can prevent the push transmission member from shifting and ensure the effectiveness of the transmission.

[0013] Preferably, the lower end surface of the push transmission member contacts the upper surface of the diffuser plate, and the lower end surface of the button contacts the bottom wall of the small groove. As long as the user presses a specific position on the diffuser plate, causing the diffuser plate to deform slightly, the deformation of the diffuser plate is transmitted to the lower end surface of the push transmission member, and then the push transmission member presses the button.

[0014] In order to make the light source board deform sufficiently when pressed, the color temperature adjustment switch is arranged at the center of the lower surface of the light source board, and the lower end surface of the pressing transmission member contacts the center of the diffusion plate. The light source board is fixedly connected to the lamp body through the edge, so when subjected to external force in the vertical direction, the center of the light source board is more likely to deform than the edge of the light source board.

[0015] Preferably, the downlight further comprises a reflector cup having a large-diameter end and a small-diameter end along the axial direction, the small-diameter end of the reflector cup is connected to the lower surface of the light source board, and the diffuser plate is clamped on the inner ring wall of the large-diameter end of the reflector cup.

[0016] In order to increase the night light function of the downlight, the downlight also includes a diffusion ring, and the first light source and the second light source are respectively provided on the light source board, the first light source is provided in the middle of the light source board, and the second light source is arranged around the first light source; the small-diameter end of the reflective cup separates the first light source and the second light source, and there is a gap between the outer shell and the reflective cup, and the diffusion ring is located in the gap.

[0017] In order to reduce the influence of the pressing transmission part on the light transmission, the pressing transmission part is made of transparent material.

[0018] Compared with the prior art, the advantages of the present invention are: the user presses the diffusion plate to cause a slight deformation of the diffusion plate, and the diffusion plate pushes the pressing transmission part upward, thereby pressing the pressing transmission part to press the color temperature adjustment switch, so that the color temperature of the light can be adjusted after the downlight is installed on the ceiling; the newly added pressing transmission part and color temperature adjustment switch have a simple structure and are easy to assemble, and there is no need to change other components of the original downlight; in addition, the newly added structure is located inside the downlight and will not affect the appearance of the downlight.
