Technical Field
[0001] This utility model relates to the field of lighting equipment, specifically to a surface-mounted downlight and its lamp holder. Background Technology
[0002] Downlights are concealed light fixtures that are embedded in the ceiling and project light downwards. They are widely used in both home decoration projects and large public places. However, downlights require pre-drilled holes for installation. In some places without suspended ceilings or where wiring cannot be hidden, conventional downlights cannot be installed. Surface-mounted downlights, on the other hand, can be directly installed on the surface of suspended ceilings or ceilings.
[0003] To reduce product inventory and improve product adaptability, a type of surface-mounted downlight has emerged on the market. The lamp holder and lamp body are detachable, meaning the lamp body can be used as a downlight. When a surface-mounted downlight is needed, the downlight is assembled onto the lamp holder and used as a surface-mounted downlight. However, due to different locations and different downlight sizes, lamp holders and downlights on the market are currently paired one-to-one. This forces manufacturers to design and store different lamp holders for different downlights, increasing product inventory and product costs. Utility Model Content

Detailed Implementation
[0037] The technical solution of this utility model will be further described below with reference to specific embodiments.
[0038] like Figures 1 to 6 As shown, this application provides a surface-mounted downlight, including: a lamp barrel 1, having a lower side surface 11, a first opening 12, and a second opening 13, wherein the first opening 12 is disposed on the lower side surface 11, and the size of the first opening 12 is smaller than the size of the second opening 13; a downlight, disposed inside the lamp barrel 1 through the first opening 12 or the second opening 13, and in contact with the lower side surface 11, the downlight including a first downlight 2 or a second downlight 3, wherein the size of the first downlight 2 is smaller than the second downlight 3; the first downlight 2 is disposed inside the lamp barrel 1 through the first opening 12; or, the second downlight 3 is disposed inside the lamp barrel 1 through the second opening 13.
[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the downlight includes a first downlight 2, which is disposed inside the lamp tube 1 through the first opening 12. The first downlight 2 has a first assembly surface 21, which contacts the front of the lower side surface 11. The lower side surface 11 has a recessed recessed portion 14, and the first opening 12 is disposed on the recessed portion 14. The size of the recessed portion 14 is adapted to the size of the first assembly surface 21, and the first assembly surface 21 is disposed on the recessed portion 14. The first downlight 2 has a first retaining spring 22, which is fixed to the lamp tube 1 by the first retaining spring 22 and the recessed portion 14. The first retaining spring 22 contacts the back of the lower side surface 11.
[0040] The specific assembly steps are as follows: the first retaining spring 22 is pried open upwards and enters the lamp tube 1 through the first opening 12. The first retaining spring 22 automatically resets and is positioned on the back of the lower side 11 to prevent the first downlight 2 from falling off. The first assembly surface 21 is embedded in the recessed part 14, which prevents the first downlight 2 from shifting, thereby achieving the purpose of assembling the first downlight 2 onto the lamp tube 1.
[0041] like Figure 4 , Figure 5 , Figure 6As shown, the downlight includes a second downlight 3, which is disposed inside the lamp tube 1 through the second opening 13. The second downlight 3 has a second assembly surface 31, which contacts the back side of the lower side surface 11. The second downlight 3 has a second light-emitting surface 32, the size of which is adapted to the size of the first opening 12. The second light-emitting surface 32 is displayed outward through the first opening 12. The second light-emitting surface 32 includes a protruding indicator portion 34. The first opening 12 has a notch 17 adapted to the position of the indicator portion 34. The indicator portion 34 is displayed outward through the notch 17.
[0042] The lamp tube 1 has two or more locking parts 15 arranged in a uniform array inside. The locking parts 15 are located on the back side of the lower side 11 and / or the side wall of the lamp tube 1. The second assembly surface 31 is locked between the first opening 12 and the locking parts 15.
[0043] The specific assembly steps are as follows: push the second downlight 3 into the lamp tube 1 through the second opening 13 until the second assembly surface 31 enters the locking part 15. The locking part 15 can prevent the second downlight 3 from falling off the lamp tube 1, thereby achieving the purpose of assembling the second downlight 3 onto the lamp tube 1.
[0044] In order to make the lamp tube 1 compatible with the second downlight 3, the lower side surface 11 of the lamp tube 1 has a larger area. The lower side surface 11 and the side wall of the lamp tube 1 can be set to a rounded corner connection to make the lamp more aesthetically pleasing.
[0045] In some embodiments, the size of the second opening 13 is adapted to the size of the second assembly surface 31, and the second downlight 3 is provided with a second retaining spring 33. The second downlight 3 is fixed inside the lamp tube 1 by the second retaining spring 33 against the inner wall of the lamp tube 1, which can also achieve the purpose of assembling the second downlight 3 onto the lamp tube 1.
[0046] The lower side 11 includes a display surface 16, and the recessed portion 14 is disposed within the area covered by the display surface 16. The first downlight 2 has a first assembly surface 21, and the second downlight 3 has a second assembly surface 31. Since downlights on the market come in various sizes, and the lamp holder 1 in this utility model can only be adapted to two sizes of downlights, in order to ensure that the downlights are more aesthetically pleasing after being assembled into the lamp holder 1 and to save costs, the area of the display surface 16 is greater than the difference between the area of the second assembly surface 31 and the area of the first assembly surface 21. It should be noted that the area of the first assembly surface 21 should refer to the area it covers. Regardless of whether the shape of the first assembly surface 21 is circular or annular, it should be calculated as the area of a circle. The area of the second assembly surface 31 is calculated in the same way.
[0047] The first downlight 2 is assembled into the lamp tube 1 using the first opening 12, or the second downlight 3 is assembled into the lamp tube 1 using the second opening 13, so that one lamp tube 1 can be compatible with two downlights of different sizes and can be used as two surface-mounted downlights with different power and brightness, reducing product accessories, saving product costs, and greatly improving product compatibility.
[0048] To improve the assembly efficiency of surface-mounted downlights, a new type of lamp holder is proposed:
[0049] like Figure 7 , Figure 8 As shown, a lamp tube includes a lower side surface 11, a first opening 12, and a second opening 13. The size of the first opening 12 is smaller than the size of the second opening 13. The lower side surface 11 has an inwardly recessed recessed portion 14, and the first opening 12 is disposed on the recessed portion 14. Two or more locking portions 15 are evenly arranged in an array inside the lamp tube 1. The locking portions 15 are disposed on the back side of the lower side surface 11 and / or the side wall of the lamp tube 1. The lower side surface 11 and the side wall of the lamp tube 1 are connected by a rounded corner. The first opening 12 has an inwardly recessed notch 17.
