Traditional downlights are usually composed of a lamp housing, a light source component, a reflector cup, and a lampshade. In the prior art, thicker lampshades are commonly used. Thick lampshades extend the light scattering path by increasing the thickness of the material, thereby uniformizing the light intensity distribution. However, the bulky appearance of thick lampshades is contrary to the trend of minimalism in interior decoration, affecting the overall aesthetics. When using a thin lampshade to optimize the appearance of downlights, due to the thin material characteristics of the thin lampshade, the light emitted by the light source quickly penetrates the surface of the lampshade and cannot be fully scattered.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0019] See also Figure 1-3 As shown, a decorative downlight, the decorative downlight comprises: Lamp housing assembly 1; a lampshade 2 is fixedly connected to the bottom surface of the lamp housing assembly 1; LED lamp beads 4; the LED lamp beads 4 are fixedly arranged on the upper wall of the inner cavity of the lamp housing assembly 1; Reflective cup 3; the reflective cup 3 is fixedly arranged between the lamp housing assembly 1 and the lampshade 2; An outer edge fill light component 5, which is fixedly arranged on the upper surface of the lampshade 2 and is used to adjust the light intensity at the center and the edge to reduce dark spots; An adjustment control component 6, which is fixedly arranged on the upper surface of the lamp housing component 1 and is used to adjust the outer edge fill light component 5; Through the above technical solution, the downlight designed in the present application has a thinner lampshade than that of an ordinary downlight, and is therefore more beautiful than an ordinary thick lampshade. Furthermore, in order to solve the problem of insufficient light source scattering and dark spots on the edge caused by the thin lampshade being too close to the light source, the present application designs an outer edge fill light component 5. Through the setting of the outer edge fill light component 5, the light can be effectively guided for the thin lampshade, so that the dark spots on the edge are improved and eliminated, making the overall light of the downlight uniform, and the adjustment is simple and convenient. It can be flexibly adjusted according to the different LED light sources, and can be used for different downlights within a certain range. While retaining the beauty of the thin lampshade, dark spots are avoided, and it is particularly suitable for decorative use.

[0020] For further technical solutions, see Figure 1 and Figure 4 As shown, the lamp housing assembly 1 includes a fixed circular plate 101, a fixed cover 102, a fixing frame 103, a spring buckle 104 and a connecting cable 105. The upper end of the fixed cover 102 is fixedly connected to the fixed circular plate 101, and a plurality of LED lamp beads 4 are fixedly connected to the bottom surface of the fixed circular plate 101. The fixed cover 102 is fixedly connected to the lampshade 2, and a connecting cable 105 is fixedly connected to the fixed circular plate 101. The connecting cable 105 is electrically connected to the LED lamp beads 4. Through the present technical solution, after the present device is installed in the corresponding position, one end of the connecting cable 105 is connected to the power supply, and the LED lamp beads 4 are illuminated by the power supply to realize the lighting function; The fixed housing 102 is fixedly connected to a fixing frame 103 on both sides, and a spring clip 104 is rotatably connected to the fixing frame 103. Through the present technical solution, by providing the spring clip 104, a slot that cooperates with the spring clip 104 can be provided at the installation position, so that the spring clip 104 can be flipped and locked in the slot, realizing the locking and fixing function, and facilitating later disassembly and removal, cleaning, replacement, etc.

[0021] For specific technical solutions, please refer to Figure 5 and Figure 6 As shown, A raised portion 201 is provided at the middle position of the lampshade 2, a recessed portion 202 is provided at the edge position of the lampshade 2, and a convex edge 203 is provided at the side of the lampshade 2. Through the present technical solution, by setting the raised portion 201 and the recessed portion 202, the lampshade 2 has a structure with a thick middle portion and a thin edge. Since the middle portion is thicker, the transmittance is reduced, and the edge is thinner, the transmittance is increased, so that it can be used to compensate for the phenomenon that the light in the middle is strong and the light at the edge is weak, thereby improving the situation of the occurrence of annular dark spots. At the same time, the setting of the convex edge 203 can wrap the side of the fixed cover shell 102, avoid light leakage at the gap when fixed, and make it more beautiful to use.

[0022] As a preferred technical solution, please refer to Figure 7 、 Figure 8 and Figure 9 As shown, The outer edge fill light assembly 5 includes a transparent ring 501, a transparent plate 502, a circular film 503, a reflective strip 504, a light guide unit 505 and a reflective ring 506. The bottom edge of the circular film 503 is fixedly arranged on the inner upper wall of the lampshade 2. The upper edge of the circular film 503 is fixedly connected to the transparent ring 501. The inner side of the transparent ring 501 is fixedly connected to the transparent plate 502. The circular membrane 503 is made of an elastic material. According to the present technical solution, the circular membrane 503 made of the elastic material can be pulled when the transparent ring 501 moves. Since the bottom end of the circular membrane 503 is fixed to the lampshade 2, the circular membrane 503 is conical. The side angle of the circular membrane 503 when forming the cone is controlled by the stretched length of the transparent ring 501. The reflective strips 504 are bonded and fixed to the surface of the circular film 503. There are a number of reflective strips 504, which are distributed in a ring array. Through this technical solution, when the transparent ring 501 moves upward to pull the circular film 503, so that the circular film 503 forms a conical structure, the reflective strips 504 are fixed on the circular film 503, thereby driving the reflective strips 504 to tilt, and the higher the transparent ring 501 is, the greater the inclination angle of the reflective strips 504 that is driven to flip upward.

[0023] For further technical solutions, see Figure 10 As shown, The light guide units 505 are provided in a plurality, and the plurality of light guide units 505 are fixed in a ring array at the outer edge of the circular film 503. The light guide units 505 include a transparent fixing seat 5051, a receiving cover 5052, a light guide bar 5053 and a condenser 5054. The transparent fixing seat 5051 is fixedly provided at the side of the circular film 503. The light guide bar 5053 is fixedly connected to the transparent fixing seat 5051. One end of the light guide bar 5053 is fixedly connected to the receiving cover 5052. The other end of the light guide bar 5053 extends to the bottom surface of the reflective ring 506. The other end of the light guide bar 5053 is fixedly connected to the condenser 5054. The reflective ring 506 is fixedly arranged at the outer edge position of the lampshade 2, and a reflective slope 5061 is arranged on the bottom surface of the reflective ring 506. Through the present technical solution, when the reflective strip 504 is tilted, part of the light can be reflected, so that the light enters the receiving cover 5052, so that the light can be transmitted to the focusing cover 5054 through the light guide strip 5053, and emitted through the focusing cover 5054. The emitted light is at the lower position of the reflective ring 506, and the reflective slope 5061 is set, so that the light is reflected and fully reflected to the peripheral edge position of the lampshade 2, so that the surrounding light can be made more sufficient, thereby achieving the reduction and improvement of the annular dark spots.

[0024] For specific technical solutions, please refer to Figure 11 、 Figure 12 and Figure 13 As shown, The adjustment and control component 6 includes a traction wire 601, a fixed bracket 602, a guide roller 603, a rectangular fixed seat 604, a limiting slider 605, a threaded rod 606 and a rotating part. The rectangular fixed seat 604 is fixedly arranged on the upper surface of the lamp housing component 1. A slide groove is provided inside the rectangular fixed seat 604. The limiting slider 605 is slidably connected in the slide groove of the rectangular fixed seat 604. One end of the traction wire 601 is fixedly connected to the side wall of one side of the limiting slider 605. The other end of the traction wire 601 passes through the inner cavity wall of the rectangular fixed seat 604 and extends outside the wall. The fixed bracket 602 is fixedly provided with a groove. The upper end of the fixing bracket 602 is rotatably connected to a guide roller 603, and one end of the traction wire 601 passes through the guide roller 603 and passes through the upper wall of the lamp housing assembly 1. The bottom end of the traction wire 601 is fixedly connected to the upper surface of the transparent plate 502. According to the present technical solution, the traction of the traction wire 601 can drive the transparent plate 502 to move upward, thereby driving the transparent ring 501 to move upward. As the transparent ring 501 moves upward, the middle part of the circular film 503 can be pulled upward, so that the circular film 503 forms a tapered structure, thereby driving the reflective strip 504 to tilt. At the same time, the longer the transparent ring 501 is pulled upward, the higher the slope of the tapered structure formed by the circular film 503 is, which drives the reflective strip 504 to adjust its inclination. When the transparent ring 501 does not move upward, the reflective strip 504 is horizontal, and light cannot enter the light guide unit 505 through reflection from the reflective strip 504. When the transparent ring 501 gradually moves upward, driving the reflective strip 504 to gradually flip and tilt, part of the light can be reflected and enter one end of the light guide unit 505 through the tilt of the reflective strip 504, thereby achieving the function of light transmission, thereby compensating for dark spots, making the lighting more uniform and more beautiful. The rotating part includes a first bevel gear 607, an adjusting knob 608, an adjusting rod 609, a second bevel gear 610, a circular groove 611, a limiting steel ball 612, a limiting spring 613 and 614. The first bevel gear 607 is fixedly arranged at the arc-shaped wall of the threaded rod 606, and the 614 is fixedly arranged at the side wall of the rectangular fixed seat 604. The adjusting rod 609 is rotatably connected to the 614. One end of the adjusting rod 609 is fixedly connected to the adjusting knob 608, and the other end of the adjusting rod 609 is fixedly connected to the second bevel gear 610. The second bevel gear 610 and the first bevel gear 607 are meshed with each other. A plurality of circular grooves 611 are provided on the arc-shaped wall of the adjusting rod 609. An inner cavity is provided inside the 614, and a limiting spring is provided in the inner cavity of the 614. Steel ball 612, one side of the limiting steel ball 612 is fixedly connected to one end of the limiting spring 613, and the other end of the limiting spring 613 is fixedly connected to the inner cavity wall of 614. Through the present technical solution, the elastic action of the limiting spring 613 can make the limiting steel ball 612 press against the circular groove 611, realizing the damping self-locking function. When adjustment operation is required, the adjusting knob 608 is manually rotated to drive the adjusting rod 609 to rotate, and then drive the second bevel gear 610 to rotate. The rotation of the second bevel gear 610 can drive the first bevel gear 607 to rotate, and then drive the threaded rod 606 to rotate. The rotation of the threaded rod 606 can drive the limiting slider 605 to move, and then drive the traction wire 601 to move, realizing the traction adjustment function.

[0025] By adjusting the coordinated use of the control component 6 and the outer edge fill light component 5, adjustment compensation can be performed, so that the lamp can be used in lampshades of different sizes and light source intensities. By adjusting to compensate for the annular dark spots, the lamp is suitable for promotion and use.
