Description

Technical Field

[0001] This utility model specifically relates to an LED surface-mounted downlight. Background Technology

[0002] With the popularization of LED lighting technology, surface-mounted downlights are widely used in commercial and residential lighting due to their convenient installation and uniform light distribution. Traditional LED surface-mounted downlights have the following technical drawbacks: most downlights use screws to fix the upper and lower cylinders, which requires tools and is cumbersome to operate, especially when working at heights, resulting in low efficiency. Utility Model Content

[0003] In view of the deficiencies of the existing technology, the technical problem to be solved by this utility model is to provide an LED surface-mounted downlight.

[0004] An LED surface-mounted downlight includes a cylindrical body and an LED light module disposed within the cylindrical body. The cylindrical body comprises an upper cylindrical body and a lower cylindrical body. The LED light module is disposed within the lower cylindrical body. The lower end of the upper cylindrical body is provided with a plurality of L-shaped connectors that are folded outwards along the circumference. The lower cylindrical body is annularly arranged, and a recessed limiting groove is provided on the inner side of the lower cylindrical body along the circumference. A first notch is provided on the upper side of the limiting groove for the L-shaped connectors to pass through, and recessed slots are provided at intervals along the circumference on the upper side of the limiting groove. The L-shaped connectors can be partially embedded in the slots.

[0005] In one embodiment, a limiting ring is provided in the limiting groove, and a threaded hole communicating with the limiting groove is opened at the lower end of the lower cylinder. A tightening screw is inserted into the threaded hole, and the tightening screw abuts against the lower side of the limiting ring.

[0006] In one embodiment, the limiting groove is provided with a plurality of metal plates evenly distributed at intervals along the circumference, and the L-shaped connector is provided with a magnet for magnetic attraction with the metal plates.

[0007] In one embodiment, a safety ring is rotatably fitted onto the upper end of the lower cylinder via a damping structure. The inner side of the safety ring has a limiting flange that can cover the first notch along its circumference. A second notch is provided on the upper side of the limiting flange for the L-shaped connector to pass through.

[0008] In one embodiment, the lower cylinder has a connecting plate that is inclined at an angle to the horizontal plane, and the LED light module is disposed on the connecting plate so that the illumination angle of the LED light module is inclined at an angle to the horizontal plane.

[0009] In one embodiment, a through-hole is formed on the connecting plate.

[0010] In one embodiment, the LED light module includes an LED light panel disposed on a connecting plate and a reflector cup sleeved on the LED light panel. The lower end opening of the lower cylinder is detachably connected to a cover shell by screws, and a light-transmitting plate is sandwiched between the cover shell and the reflector cup.

[0011] In summary, the advantages of this utility model over the prior art are:

[0012] This utility model fixes the upper cylinder to the ceiling, and then the L-shaped connector of the upper cylinder is movably accommodated in the limiting groove of the lower cylinder through the first notch. The weight of the lower cylinder causes the slot to fit into the L-shaped connector, thereby realizing a quick installation logic of "insertion-rotation-locking".

[0013] Furthermore, the LED light module is tilted due to the inclination of the connecting plate of the lower cylinder, so that its illumination angle is set at an angle to the horizontal plane. Thus, when the lower cylinder rotates relative to the upper cylinder, it can adjust and change the horizontal circumferential illumination angle of the LED light module. And through the L-shaped connector and the corresponding slot in the limiting groove, the horizontal circumferential illumination angle of the downlight can be adjusted and installed.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0018] like Figures 1 to 3The present invention preferably provides an LED surface-mounted downlight, including a cylindrical body and an LED light module 1 disposed within the cylindrical body. The cylindrical body includes an upper cylindrical body 2 and a lower cylindrical body 3. The LED light module 1 is disposed within the lower cylindrical body 3. The lower end of the upper cylindrical body 2 has several L-shaped connectors 4 arranged outwardly folded along its circumference. The lower cylindrical body 3 is annularly arranged, and a recessed limiting groove 5 is provided on the inner side of the lower cylindrical body along its circumference. A first notch 6 is provided on the upper side of the limiting groove 5 for the L-shaped connectors 4 to pass through, and recessed slots 7 are provided at intervals along the circumference on the upper side of the limiting groove 5. The L-shaped connectors 4 can be partially embedded in the slots 7. Specifically, the upper cylindrical body is fixed to the ceiling, and the L-shaped connectors of the upper cylindrical body are movably accommodated in the limiting grooves of the lower cylindrical body through the first notch. The weight of the lower cylindrical body causes the slots to engage with the L-shaped connectors, thereby achieving a rapid installation logic of "insertion-rotation-locking".

[0019] Furthermore, a limiting ring 8 is movably installed vertically within the limiting groove 5. A threaded hole communicating with the limiting groove 5 is provided at the lower end of the lower cylinder 3. A tightening screw 9 is threaded into the threaded hole and abuts against the lower side of the limiting ring 8. Specifically, the tightening screw can be a nut screw, allowing the user to tighten it to move the limiting ring upwards relative to the limiting groove. This causes the limiting ring to press upwards against the L-shaped connector, keeping the L-shaped connector engaged in the groove.

[0020] Furthermore, the limiting groove 5 is provided with a plurality of metal pieces 10 evenly distributed at intervals along the circumference, and the L-shaped connector 4 is provided with a magnet 11 for magnetic attraction with the metal pieces 10. Thus, the upper cylinder is positioned and fixed in the horizontal circumferential direction relative to the lower cylinder by magnetic attraction between the magnet on the L-shaped connector and one of the metal pieces in the limiting groove.

[0021] Furthermore, a safety ring 12 is rotatably fitted onto the upper end of the lower cylinder 3 via a damping structure. The inner side of the safety ring 12 has a circumferentially protruding limiting flange 14 that covers the first notch 6. A second notch 15 is provided on the upper side of the limiting flange 14 for the L-shaped connector 4 to pass through. Specifically, the damping structure is a relatively mature existing technology, and its structural principle will not be detailed here. By rotating the safety ring, the limiting flange on the inner side of the safety ring rotates accordingly and covers the first notch, effectively preventing the L-shaped connector from disengaging from the limiting groove and avoiding accidental disassembly of the upper and lower cylinders. Furthermore, when the upper and lower cylinders are installed relative to each other, the second notch on the safety ring is aligned with the first notch of the limiting groove by rotating the safety ring.

[0022] Furthermore, the lower cylinder 3 has a connecting plate 16 inclined at an angle to the horizontal plane, and the LED light module 1 is disposed on the connecting plate 16 so that the illumination angle of the LED light module 1 is inclined at an angle to the horizontal plane. Thus, by tilting the connecting plate of the lower cylinder, the illumination angle of the LED light module is set at an angle to the horizontal plane. Therefore, when the lower cylinder rotates relative to the upper cylinder, the horizontal circumferential illumination angle of the LED light module can be adjusted and changed. Furthermore, the adjustment and installation of the downlight's horizontal circumferential illumination angle is achieved by the L-shaped connector engaging with the corresponding locking groove.

[0023] Furthermore, a through hole 17 is provided on the connecting plate 16.

[0024] Furthermore, the LED light module 1 includes an LED light plate 21 mounted on a connecting plate 16 and a reflector 22 sleeved on the LED light plate 21. A cover 23 is detachably connected to the lower opening of the lower cylinder 3 via screws. A light-transmitting plate 24 is held between the cover 23 and the reflector 22. The cover is then connected to the lower cylinder via screws, and the cover and reflector form a clamping structure, enabling convenient installation.
