Description

Technical Field

[0001] The present disclosure relates to the technical field of kitchen lighting downlights, and in particular to a waterproof magnetic structure and a kitchen lighting downlight. Background Art

[0002] Kitchen downlights are typically used for lighting in kitchens, a high-temperature, high-humidity environment. Cooking generates large amounts of fumes and steam, which can cause short circuits when they enter the downlight. Furthermore, the fumes and steam can adhere to the surface of the downlight's shade, forming oil stains. This not only affects the lighting effect but can also damage the downlight. Furthermore, downlight bulbs are fragile components and require regular replacement. To address these issues, further research and development has been conducted on related technologies and products.

[0003] Existing technology, such as patent CN203162615U, proposes a new type of LED downlight, which includes a cover, a hexagon socket screw, a waterproof rubber ring, a spring sleeve, a spring, a countersunk screw, a silicone gasket, a pan head screw, a rotating ring, a rotating ring, a spring clip, a locking ring, a grid, a waterproof ring, a tempered glass, a glare cover, screws,

[0004] The mounting bracket, LED light source COB, heat sink assembly, wire retainer, female plug wire, male plug wire and driver power supply, the cover, hexagon socket screw, waterproof rubber ring, spring sleeve, spring, countersunk screw, silicone gasket, pan head screw, rotating ring, rotating ring, spring clip, locking ring, mesh, waterproof ring, tempered glass, glare cover, screws, mounting bracket, LED light source COB, heat sink assembly, wire retainer, female plug wire, male plug wire and driver power supply are installed and fixed together in sequence. The above utility model downlight is waterproof.

[0005] However, the bulbs of these new LED downlights require regular replacement. Over time, the tempered glass surface of these downlights will become greasy and require regular cleaning. Furthermore, the waterproof rubber rings of these downlights age over time, reducing their sealing properties and requiring regular replacement. However, the difficulty of disassembling and installing these downlights not only greatly increases the difficulty of bulb replacement and maintenance, but also makes cleaning and replacement of the waterproof rings more difficult, significantly reducing their ease of use.
