[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0024] like Figures 1 to 5 The embodiment of the utility model shown preferably provides a quick-install and easy-to-disassemble downlight, including a cylinder body 1, and a light source module 2, a light-transmitting plate 3 and a face cover 4 stacked in the inner cavity of the cylinder body 1 from top to bottom, the face cover 4 being sleeved on the lower end of the cylinder body 1 by threaded fitting, the light source module 2 and the light-transmitting plate 3 being clamped between the face cover 4 and the cylinder body 1, the inner cavity of the cylinder body 1 is rotatably provided with an annular limit frame 5 which is arranged coaxially with the inner cavity of the cylinder body 1, and a plurality of groups of limit protrusions 6 are arranged on the inner side of the annular limit frame 5 from top to bottom, and the plurality of groups of limit protrusions 6 are respectively and one by one arranged below the light source module 2 and the light-transmitting plate 3 and can abut against the lower side of the light source module 2 and the light-transmitting plate 3; when the face cover 4 is disassembled and detached from the cylinder body 1, the light source module 2 and the light-transmitting plate 3 can be correspondingly suspended on different groups of limit protrusions 6.

[0025] Specifically, the light source module and the light-transmitting plate are fixedly clamped between the cylinder and the surface cover in sequence by screwing the threads of the surface cover and the cylinder, thereby realizing the installation and fixation of the cylinder, the light source module, the light-transmitting plate and the surface cover. When disassembly is required, the light source module and the light-transmitting plate can be disassembled by screwing the surface cover, realizing quick installation and facilitating subsequent disassembly, maintenance and replacement.

[0026] In order to avoid the problem that the light source module and the light-transmitting plate fall directly due to separation from the support of the face cover when the face cover is disassembled from the cylinder, the utility model arranges an annular limit frame in the cylinder, and several groups of limit protrusions at different horizontal heights in the annular limit frame respectively abut and support the light source module and the light-transmitting plate, thereby effectively avoiding the problem of the light source module and the light-transmitting plate falling directly. When the light source module and the light-transmitting plate need to be completely disassembled and removed, the annular limit frame can be manually rotated so that the notches in the light source module and the light-transmitting plate can respectively pass over the corresponding limit protrusions.

[0027] When the surface cover is fastened to the cylinder to clamp the light-transmitting plate and the light source module, the plurality of groups of limiting protrusions in the annular limiting frame are in a non-contact state with the corresponding light source modules and light-transmitting plates.

[0028] Furthermore, the outer shape of the face cover 4 is annular, and a first flange 41 is convexly provided on the inner ring side wall along the circumference, and a recessed groove 42 is provided on the upper side of the first flange 41, and the lower end of the annular limiting frame 5 is provided in the recessed groove 42, and a gap is left between the lower end of the annular limiting frame 5 and the bottom wall of the recessed groove 42. Therefore, when the face cover 4 is tightly pressed against the lower side of the light-transmitting plate 3 through the thread, the lower end of the annular limiting frame 5 does not contact the bottom wall of the recessed groove 42.

[0029] Furthermore, the light-transmitting plate 3 is provided with a first notch 31 corresponding to the limiting protrusion 6, and the light-transmitting plate 3 can pass over the limiting protrusion 6 and abut against the light source module 2 through the first notch 31. When the light-transmitting plate passes over the corresponding limiting protrusion through the first notch so that the light-transmitting plate abuts against the light source module, the annular limiting frame is manually rotated so that the limiting protrusion corresponding to the light-transmitting plate in the annular limiting frame and the first notch are staggered, thereby achieving the installation of the light-transmitting plate and the limiting protrusion of the annular limiting frame can achieve anti-drop support for the light-transmitting plate after the face cover is removed.

[0030] Furthermore, the light source module 2 includes an LED light board 21, a lamp holder 22, a lens 23 and a reflective cup 24. The lamp holder 22 is provided with a light-transmitting hole 25. The upper side of the lamp holder 22 is concave with a recessed groove connected to the light-transmitting hole 25. The LED light board 21 is embedded in the recessed groove and is located in the light-transmitting hole 25. The reflective cup 24 has upper and lower openings, and the lens 23 is embedded in the upper opening of the reflective cup 24. Several groups of limiting protrusions 6 are respectively arranged one by one under the reflective cup 24 and the lamp holder 22 and can abut against the lower side of the reflective cup 24 and the lamp holder 22.

[0031] Specifically, the LED light board is embedded in the lamp holder so that the LED light board and the lamp holder form an integrated module, the lens is embedded in the upper opening of the reflective cup so that the lens and the reflective cup form an integrated module, and then different groups of limiting protrusions in the annular limiting frame are respectively arranged corresponding to the reflective cup and the lamp holder.

[0032] Furthermore, a second flange 26 is protruded along the circumference of the outer side of the reflective cup 24, and a second notch 27 is formed on the second flange 26 corresponding to the limiting protrusion 6, so that the reflective cup 24 can pass over the limiting protrusion 6 and abut against the lower side of the lamp holder 22 through the second notch 27; the outer wall of the reflective cup 24 abuts against the inner wall of the annular limiting frame 5.

[0033] Specifically, when the reflective cup passes over the corresponding limiting protrusion through the second notch so that the lens on the upper side of the reflective cup abuts against the lamp holder, the annular limiting frame is manually rotated so that the limiting protrusion corresponding to the reflective cup and the second notch in the annular limiting frame are staggered, thereby realizing the installation of the reflective cup and the limiting protrusion of the annular limiting frame can provide anti-fall support for the reflective cup after the face cover is removed.

[0034] Furthermore, the lamp holder 22 is provided with a third notch 28 corresponding to the limiting protrusion 6, and the reflective cup 24 can pass over the limiting protrusion 6 and be located at the top of the inner cavity of the cylinder 1 through the third notch 28. Specifically, when the lamp holder passes over the corresponding limiting protrusion through the third notch so that the LED lamp board on the reflective cup abuts against the top wall of the inner cavity of the cylinder, the annular limiting frame can be manually rotated so that the limiting protrusion corresponding to the lamp holder in the annular limiting frame and the third notch are staggered, thereby achieving the installation of the lamp holder and the limiting protrusion of the annular limiting frame can provide anti-drop support for the lamp holder after the face cover is removed.

[0035] Furthermore, the inner cavity of the cylinder 1 is provided with a guide shaft 11, and the lamp holder 22 is sleeved on the guide shaft 11, thereby realizing the positioning and installation of the lamp holder.

[0036] Furthermore, each group of limiting protrusions 6 has two or more evenly distributed along the circumference of the annular limiting frame 5, and different groups of limiting protrusions 6 are staggered. Then, the staggered positioning of different groups of limiting protrusions facilitates each component to sequentially pass over the corresponding limiting protrusion and then fall when the annular limiting frame is manually rotated.

[0037] Furthermore, the inner cavity of the cylinder 1 is concave with a groove 12 along the circumferential side wall, and screw holes 13 are provided on both sides of the annular limit frame 5 corresponding to the groove 12, and the screw holes 13 are threadedly connected with connecting screws, and one end of the connecting screws extends into the groove 12. Thus, the annular limit frame can be installed and rotated relative to the cylinder.

[0038] Furthermore, a plurality of heat dissipation fins 14 are provided at intervals along the circumference of the outer wall of the cylinder 1, thereby facilitating heat dissipation.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
