Referring to Figure 1 The lower end of the first cavity 3 is open and forms the first opening 4, and the inner wall of the first cavity 3 is in a spherical shape. Referring to Figure 4 The diameter of the first opening 4 is smaller than the diameter of the inner wall of the first cavity 3. Referring to Figure 1 Or Figure 4 The top cover 19 is fixed to the top of the upper seat 1 and is provided with a threading hole 20 extending to the first cavity 3; the upper shell 18 is fixed to the upper seat 1, and the driving assembly is arranged in the upper shell 18. Referring to Figure 1 、 Figure 2 and Figure 4 The lower sealing plate 12 is fixed to the bottom of the lower seat 2 and is provided with a limiting flange 14 extending inward, which protrudes from the inner side edge of the first opening 4.
[0044] Specifically, referring to Figure 1 The upper seat 1 and the lower seat 2 are both circular ring members, the outer periphery of which is a circular ring wall surface, and the inner wall is in a spherical shape. Here, the spherical shape can be regarded as a spherical surface with a proper diameter, which is cut by a plane perpendicular to the up-down direction, that is, the horizontal direction, to leave the middle part on the upper side and the lower side. Therefore, the upper side and the lower side of the first cavity 3 both have openings, wherein the lower end of the first cavity 3 forms the first opening 4 which is open downward, and the upper end is closed by the fixing of the top cover 19 to the upper seat 1. According to the shape characteristics of the first cavity 3, it can be considered that the first cavity 3 has a diameter in the horizontal direction. Specifically, referring to Figure 4 That is, the intersection line of the inner wall of the first cavity 3 and the horizontal plane forms a circle with the largest diameter, and the diameter of the circle is the diameter of the first cavity 3. Compared with the diameter, the shape of the first opening 4 is also a circle, and the diameter of the first opening 4 is smaller than the diameter of the first cavity 3. At the same time, the position of the circle with the largest diameter formed by the intersection line of the inner wall of the first cavity 3 and the horizontal plane is the lower edge of the upper seat 1 and the upper edge of the lower seat 2.
[0045] Referring to Figure 1 and Figure 4 A clamping groove is arranged on the outer side of the upper seat 1, and an elastic buckle is arranged on the lower seat 2. Through the clamping and cooperation of the elastic buckle and the clamping groove, the upper seat 1 and the lower seat 2 can be integrally detachably fixed, and a first cavity 3 with a smooth surface can be formed in cooperation.
[0046] Referring to Figure 1 and Figure 4The lower sealing plate 12 is a circular plate member with a hole in the middle to expose the first chamber 3, and extends outward to form a clamping flange 13 and inward to form a limiting flange 14. The lower sealing plate 12 is fixed to the lower base 2 by clamping or screwing, and can cooperate with the spring clamp provided on the down lamp to clamp and fix the down lamp on the ceiling. Figure 4 The limiting flange 14 protrudes from the inner side of the first opening 4.
[0047] Referring to Figure 1 The lamp body includes a light emitting assembly 5, a lamp holder 6, and an elastic rubber ring 9.
[0048] Referring to Figure 1 The light emitting assembly 5 is adapted to emit light; the lamp holder 6 is provided with a second chamber 7 for fixedly mounting the light emitting assembly 5, and the lower end of the second chamber 7 is open to form a second opening 8, and the opening direction of the second opening 8 is consistent with the lighting direction of the light emitting assembly 5. Referring to Figure 2 and Figure 4 The lamp holder 6 is adapted to be mounted to the first chamber 3, and the outer periphery thereof is a spherical surface adapted to the inner wall of the first chamber 3, and the diameters thereof are adapted to allow the lamp holder 6 to adjust the position in the first chamber 3. Referring to Figure 2 and Figure 4 The elastic rubber ring 9 is sleeved on the outer periphery of the lamp holder 6 and abuts against the inner wall of the first chamber 3.
[0049] Specifically, referring to Figure 1 The light emitting assembly 5 includes a light emitting piece 16 and a reflector cup 17, the light emitting piece 16 is fixedly arranged on the top of the second chamber 7, and the reflector cup 17 is fixedly connected to the lamp holder 6 and located below the light emitting piece 16. The light emitting piece 16 includes a circuit substrate and an LED lamp bead, the LED lamp bead is fixed on the circuit substrate, the circuit substrate is fixed on the top wall of the second chamber 7 provided by the lamp holder 6, and the top wall of the lamp holder 6 is provided with an opening, the driving assembly is connected to the light emitting piece 16 through the wire hole 20 provided on the top cover 19 and then through the opening on the top wall of the lamp holder 6, and the position change of the lamp body does not affect the electrical connection between the driving assembly and the light emitting piece 16. Referring to Figure 4 The reflector cup 17 is fixedly arranged on the lower side of the lamp holder 6 and located below the light emitting piece 16. The reflector cup 17 can improve the concentration of the light emitted by the light emitting piece 16 and improve the illumination intensity, and the reflector cup 17 limits the lighting direction of the lamp body. In Figure 4 the lighting direction of the lamp body is considered to be vertically downward.
[0050] Referring to Figure 1 and Figure 2The outer periphery of the lamp holder 6 is spherical, but the upper and lower portions thereof are planar. The lamp holder 6 can be fitted into the first chamber 3 formed by the upper seat 1 and the lower seat 2, and the diameter of the outer periphery of the lamp holder 6 is adapted to the diameter of the first chamber 3, so that the lamp holder 6 can adjust its position in the first chamber 3. At the same time, since the diameter of the outer periphery of the lamp holder 6 is greater than the diameter of the first opening 4, the lamp holder 6 cannot be separated from the first chamber 3 at the first opening 4. In this case, the fitting of the lamp holder 6 becomes a problem. For this reason, the down lamp provided in the embodiment sets the first chamber 3 to be formed by the cooperation of the upper seat 1 and the lower seat 2, and the upper seat 1 and the lower seat 2 can be detachably fixed. Therefore, when the lamp holder 6 is installed, the upper seat 1 and the lower seat 2 can be separated first, then the upper portion of the lamp holder 6 is attached to the inner wall of the upper seat 1, and then the lower seat 2 is buckled to the lamp holder 6 and the upper seat 1, thereby completing the fitting of the lamp holder 6. The second chamber 7 is arranged on the inner side of the lamp holder 6, the lower end of the second chamber 7 forms a second opening 8, the light emitting member 16 can be installed into the top wall of the lamp holder 6 through the second opening 8, and the reflecting cup 17 is also installed in the second chamber 7.
[0051] At the same time, referring to Figure 1 and Figure 4 , a circumferential rubber ring groove 15 is arranged on the outer periphery of the lamp holder 6, and the elastic rubber ring 9 is arranged in the rubber ring groove 15. The rubber ring groove 15 is arranged around the outer periphery of the lamp holder 6, the size of the elastic rubber ring 9 is adapted to the size of the rubber ring groove 15, the elastic rubber ring 9 can be installed in the rubber ring groove 15 by its deformation, and the elastic rubber ring 9 will protrude from the slot of the rubber ring groove 15, so that the elastic rubber ring 9 can be kept abutting to the inner wall of the first chamber 3. The elastic rubber ring 9 is sleeved on the outer periphery of the lamp holder 6, which can increase the friction between the lamp body and the inner wall of the first chamber 3, so that the lamp body can be parked at the desired position, and will not be restored to the original position under the action of gravity; at the same time, the elastic rubber ring 9 can also play a waterproof role, avoiding the entry of external water vapor into the down lamp. Moreover, the elastic rubber ring 9 is arranged in the rubber ring groove 15 on the outer periphery of the lamp holder 6, which can avoid the displacement of the elastic rubber ring 9, and ensure that there is enough friction between the lamp body and the inner wall of the first chamber 3.
[0052] In addition, referring to Figure 4 , a first limiting portion 10 is arranged on the upper side of the upper seat 1; the first limiting portion 10 protrudes from the inner wall of the first chamber 3; the lamp holder 6 is provided with a second limiting portion 11 corresponding to the first limiting portion 10, and the lamp holder 6 is configured to be adapted to limit its inclination angle relative to the horizontal direction by the abutting cooperation of the first limiting portion 10 and the second limiting portion 11. Wherein, the first limiting portion 10 is continuously arranged along the circumference of the first chamber 3; the second limiting portion 11 is continuously arranged along the circumference of the lamp holder 6.
[0053] Specifically, the first limiting portion 10 can be regarded as a protruding beam arranged on the inner wall of the first chamber 3, and the second limiting portion 11 is the upper edge of the outer periphery of the lamp holder 6. Referring toFigure 3 、 Figure 4 and Figure 5 When the lamp holder 6 is pressed from bottom to top at the edge position, the lamp holder 6 can change the position in the first chamber 3, which can be considered as the lamp holder 6 is inclined relative to the horizontal direction. When the second limiting part 11 on the lamp holder 6 abuts to the first limiting part 10, the lamp holder 6 can be limited at the upper position by the first limiting part 10, and the lamp holder 6 cannot continue to increase the inclination angle. In addition, the limiting flange 14 of the lower sealing plate 12 of the shell is also suitable for limiting the inclination angle of the lamp holder 6 relative to the horizontal direction by abutting with the elastic rubber ring 9. That is, when the elastic rubber ring 9 sleeved on the lamp holder 6 abuts to the limiting flange 14, the lamp holder 6 cannot continue to incline. The inclination angle of the lamp holder 6 is limited from the upper and lower positions, so that the lamp light is not blocked by the shell due to the too large inclination angle of the lamp holder 6.
[0054] The embodiment provides a down lamp with adjustable lighting direction, which comprises a shell and a lamp body. The shell comprises an upper seat 1 and a lower seat 2 which can be detachably and fixedly connected along the up-down direction. The upper seat 1 and the lower seat 2 can form a first chamber 3 after being assembled into one. The lamp body can be installed in the first chamber 3. The inner wall of the first chamber 3 and the outer periphery of the lamp holder 6 are mutually adapted spherical surfaces. The cooperation of the shapes can enable the lamp holder 6 to adjust its position in the first chamber 3 relative to the shell. Meanwhile, the second chamber 7 is arranged in the lamp holder 6. The light emitting assembly 5 can be arranged in the second chamber 7 and emit light outward through the second opening 8 at the lower end of the second chamber 7. The lower end of the first chamber 3 is also provided with the first opening 4, so that the light can be diffused outward. When assembling, the lamp body can be first attached to the inner wall of the upper seat 1, and then the lower seat 2 is assembled to the upper seat 1, so that the lower seat 2 and the upper seat 1 cooperate to limit the lamp holder 6 of the lamp body, facilitating the installation of the lamp body. Since the diameter of the first opening 4 at the lower end of the first chamber 3 is smaller than the diameter of the inner wall of the first chamber 3, the lamp body can adjust the position in the first chamber 3 and will not fall off from the first chamber 3.
[0055] The above description and embodiment are used to explain the protection scope of the utility model, but do not constitute the limitation on the protection scope of the utility model. Through the inspiration of the utility model or the above embodiment, the modification, equivalent replacement or other improvement of the utility model embodiment or one part of the technical features obtained by the logical analysis, reasoning or limited test of the ordinary skill in the art combined with the common knowledge, the ordinary skill in the art and / or the prior art should be included in the protection scope of the utility model.
