[0024] like Figures 1 to 5 As shown, this embodiment provides a downlight with a convenient reflector cup replacement, including a lamp housing 1, an LED light source, and a reflector cup 2. One side of the lamp housing 1 has an opening, and the LED light source is located inside the opening at the bottom of the lamp housing 1. The reflector cup 2 is located inside the opening of the lamp housing 1. At least two protrusions 11 are provided on the inner sidewall of the lamp housing 1. A limiting strip 21 is provided on the outer side of the reflector cup 2, and a stop block 22 is provided at one end of the limiting strip 21. A protrusion 23 is provided on the limiting strip 21. When the reflector cup 2 is installed inside the lamp housing 1, rotating in the opposite direction causes the protrusions 11 to move along the limiting strip 21. The protrusions 11 prevent the lamp housing 1 from separating from the reflector cup 2. When it moves to the protrusion 23, a little force is needed to cross the protrusion 23 onto the stop block 22, confining it between the stop block 22 and the protrusion 23. This facilitates disassembly and installation. Production and inventory are prepared according to user needs, making replacement convenient and highly versatile.

[0025] As an optional embodiment, a lens 3 is mounted on the reflector cup 2, which can improve light efficiency through refraction.

[0029] As an optional embodiment, a wire clamp 13 is fixed to the rear side of the lamp housing 1. The wire clamp 13 is used to clamp the wire tightly to prevent the wire from detaching from the LED light source and improve safety.

[0030] In existing technology, the reflector cups inside downlights are difficult to disassemble, making it difficult to replace different colored reflectors, resulting in high production and inventory costs and inconvenient installation. Therefore, a downlight with a convenient reflector cup replacement is provided. The reflector cup 2 is located inside the opening of the lamp housing 1. The inner side wall of the lamp housing 1 is provided with at least two protrusions 11. A limiting strip 21 is provided on the outer side of the reflector cup 2. A stop block 22 is provided at one end of the limiting strip 21. A protrusion 23 is provided on the limiting strip 21. When moving to the protrusion 23, a little force is needed to cross the protrusion 23 onto the stop block 22, and the light is confined between the stop block 22 and the protrusion 23. This makes disassembly and installation convenient, production and inventory can be prepared according to user needs, replacement is convenient, and versatility is strong.
