[0030] like Figures 1 to 6As shown, this embodiment provides a downlight with a convenient light source component replacement, including a lamp housing 1, a lamp cup 2, and a light source component 3. The lamp housing 1 has a through hole in its center. The front periphery of the light source component 3 is provided with a first step 31 and a first slot 32 between the first steps 31. Three first steps 31 are provided. The first slot 32 is located between two first steps 31. The lamp cup 2 is provided with a receiving step 21 and a limiting ring 22 around the receiving step 21. The limiting ring 22 is provided with limiting protrusions 23 corresponding to the first slots 32. Three limiting protrusions 23 are provided and correspond to the first slots 32. According to the position, the light source assembly 3 is placed on the receiving step 21 of the lamp cup 2 through the cooperation of the first slot 32 and the limiting protrusion 23. The first step 31 will fit against the receiving step 21. By rotating the light source assembly 3 and the lamp cup 2 in opposite directions, the first step 31 is locked in the limiting protrusion 23, realizing the fixed state of the lamp cup 2 and the light source assembly 3. It can be disassembled and separated by rotating in the opposite direction. At least two limiting posts 24 are provided on the periphery of the lamp cup 2. The limiting posts 24 are in opposite positions of the lamp cup 2. The outer side of the lamp housing 1 is provided with a second slot 11. The lamp cup 2 is placed in the through hole of the lamp housing 1. Figure 8 As shown, in the first embodiment, the limiting post 24 is rotatably fastened in the second slot 11 for detachable fixation. The lamp cup 2 and the light source assembly 3 are detachably connected by engaging in the limiting protrusion 23 through the first step 31. The lamp housing 1 and the lamp cup 2 are rotatably fastened in the second slot 11 through the limiting post 22 for detachable fixation. This makes it easy to install and remove the light source assembly 3, which simplifies maintenance. The lamp housing 1 does not need to be replaced, saving resources and being more environmentally friendly.

[0031] Furthermore, in existing technologies, lamp cups are generally fixedly connected to the outer shell, making it difficult to disassemble and replace them. By rotating the lamp shell 1 and lamp cup 2 into the second slot 11 through the limiting post 22, the lamp cup 2 can be detachably fixed, allowing the lamp cup 2 to be separated from the lamp shell 1. Once the lamp shell 1 is separated from the light source assembly 3, lamp cups 2 of different shapes or colors can be replaced to meet the needs of users, and the quantity of goods that distributors need to keep can also be reduced, allowing for free combination and matching.

[0032] like Figure 7 As shown, another method is provided, in which an outer ring 25 is provided on the front side of the lamp cup 2, the diameter of the outer ring 25 being larger than the through hole of the lamp housing 1, the lamp housing 1 being confined between the limiting post 24 of the lamp cup 2 and the outer ring 25, and an avoidance groove 12 is provided inside the lamp housing 1, the limiting post 24 passing through the avoidance groove 12 and then rotating and engaging in the second slot 11, thus making installation and disassembly more convenient.

[0033] Preferably, a baffle 33 is provided on one side of the first slot 32 of the light source assembly 3, and the baffle 33 can restrict the rotation of the light source assembly 3 in one direction.

[0034] Preferably, spring clips are provided on both sides of the lamp housing 1, and the spring clips are used to fix the downlight to the ceiling.

[0035] Preferably, the bottom of the limiting post 24 has an arc-shaped structure, which makes it easy for the limiting post 24 to move into the second slot 11 and prevents it from getting stuck.

[0036] Preferably, the light source assembly 3 is provided with an anti-slip protrusion 34 on its periphery, which facilitates the rotation of the light source assembly 3.

[0037] Preferably, the light source assembly 3 includes a housing 35, an LED light source 36, and a lens 37. An opening is provided on one side of the housing 35, the LED light source 36 is installed deep within the opening, and the lens 37 is installed on the surface of the opening. A dimming box 38 is provided on the rear side of the housing 35, and a dimming module 381 is provided inside the dimming box 38. The dimming module 381 is electrically connected to the LED light source 36, and a dimming switch 382 is provided on the dimming module 381. The housing 35 and the dimming box 38 are fastened together. The LED light source 36 includes at least two sets of LED beads of different colors, one white and one yellow. The dimming switch 382 has three positions: one for white light and one for yellow light, one for yellow light and one for white light and one for both white and yellow light. The dimming switch 382 turns on one or two sets of LED beads, and when both sets are activated, they create a mixed light, resulting in brighter light. This structure facilitates distributors' inventory preparation, reduces stockpiling, and makes switching easier for users.
