The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0032] like Figures 1 to 8 As shown, a downlight with adjustable installation size includes a housing 1, a slide rail 2 protruding upward and extending toward the edge of the housing 1, and the cross section of the slide rail 2 is a structure that is wide at the top and narrow at the bottom; a sliding member 3 is arranged above the slide rail 2, and a sliding portion 4 matching the shape of the slide rail 2 is arranged in the slide rail 3; and a retaining spring 5 is arranged on the slide rail 3. By arranging the slide rail 2 on the housing 1 and the sliding portion 4 on the slide rail 3, the slide rail 3 can adjust the position by using the slide rail 2 and the sliding portion 4, and drive the retaining spring 5 to move, so as to adjust different installation sizes and make the lamp suitable for reserved holes of different sizes. The slide rail 2 protrudes upward from the surface of the housing 1, and does not destroy the sealing of the housing 1, thereby preventing water vapor and insects from entering the interior of the lamp from the surface of the housing 2, and improving the protection level of the lamp.

[0033] It is worth noting that: in this embodiment, the housing is circular, and may also be other shapes, such as rectangular. The number of the slide rail 2 and the slide member 3 may be one or a pair, preferably a pair.

[0034] The slide rail 2 includes a fixing portion 21 and a connecting portion 22, wherein the fixing portion 21 is arranged above the connecting portion 22, and the width of the fixing portion 21 is greater than the width of the connecting portion 22; the sliding portion 4 includes a fixing hole 41 and an opening portion 42, wherein the opening portion 42 is connected to the fixing hole 41 and passes through the bottom of the sliding member 3, and the width of the fixing hole 41 is greater than the width of the opening portion 42, the fixing hole 41 is adapted to the fixing portion 21, and the opening portion 42 is adapted to the connecting portion 22; the cross-section of the slide rail 2 is in a "T" shape; the sliding portion 4 is in a "T" shape, and the slide rail 2 is arranged in the sliding portion 4. The fixing portion 21 is arranged on the shell 1 through the connecting portion 22, and the sliding member 3 enters the slide rail 2 through the opening portion 42. The opening portion 42 is connected to the connecting portion 22, and the fixing hole 41 is connected to the fixing portion 21. Since the width of the opening portion 42 is smaller than the width of the fixing portion 21, the sliding member 3 can be effectively prevented from falling off, thereby achieving the purpose of fixing the sliding member 3, and the sliding member 3 can also move along the slide rail 2 and drive the retaining spring 5 to move, thereby realizing the adjustment of different installation dimensions, so that the lamp is suitable for reserved holes of different sizes.

[0035] The shell 1 is provided with an intercepting edge 11, which is connected to the slide rail 2. The intercepting edge 11 is arranged at a portion of the shell 1 close to the edge. The length of the intercepting edge 11 is greater than the length of the sliding member 3. The distance between the intercepting edge 11 and the edge of the shell 1 is greater than the width of the sliding member 3. When the shell 1 is installed to the reserved hole, the corresponding forces between the retaining spring 5 and the shell 1 are required to clamp the ceiling between the retaining spring 5 and the shell 1. If the retaining spring 5 exceeds the range of the shell 1, the shell 1 cannot be installed. The intercepting edge 11 can limit the moving distance of the sliding member 3 to prevent the sliding member 3 from detaching from or protruding from the edge of the shell 1, which makes the shell 1 unable to be installed or unsightly after installation.

[0036] The sliding member 3 is fixed by the downward corresponding force generated by the sliding member 3 when the retaining spring 4 tilts upward. This structure can make the sliding member 3 easy and convenient to adjust its position, speed up the installation, and make it strong and firm after installation and not easy to fall off.
