[0044] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0045] See also Figure 1-Figure 10 , shows a downlight with adjustable light-emitting angle in a preferred embodiment of the utility model, comprising:

[0046] A mounting base 1, wherein the mounting base 1 has a mounting cavity 13 and a light-transmitting hole, wherein the light-transmitting hole is located at the bottom of the mounting base 1 and is communicated with the mounting cavity 13;

[0047] The lamp body 2, at least the upper part of the lamp body 2 is arranged in the installation cavity 13, the lamp body 2 covers the light-transmitting hole, the lamp body 2 and the installation cavity 13 are gap-matched, and the two lateral opposite outer sides of the lamp body 2 are pivotally connected to the installation base 1, so that the lamp body 2 can swing left and right to change the light-emitting angle of the lamp body 2.

[0048] The downlight of the utility model is based on the clearance fit between the lamp body 2 and the installation cavity 13 and the two relatively outer sides of the lamp body 2 are pivotally connected to the installation base 1, so that the lamp body 2 can swing to the left and make the light-emitting angle of the lamp body 2 tilt to the left relative to the vertical center line of the lamp body 2, and the lamp body 2 can swing to the right and make the light-emitting angle of the lamp body 2 tilt to the right relative to the vertical center line of the lamp body 2. The light-emitting angle of the lamp body 2 can be changed, the light-emitting angle of the lamp body 2 is more diversified, and it supports manual adjustment of the light-emitting angle of the lamp body 2 during installation, which can meet various application scenarios and is more flexible and convenient to use.

[0049] It can be understood that the mounting base 1 is inserted into a hole groove of a wall or ceiling, and two opposite lateral outer sides of the mounting base 1 are provided with retaining springs 14, which abut against the side walls of the hole groove to achieve fixed installation of the downlight.

[0050] See also Figure 6-Figure 7 In one embodiment, the inner wall of the installation cavity 13 is provided with a first limiting protrusion 111 and a second limiting protrusion 112, the first limiting protrusion 111 and the second limiting protrusion 112 are arranged opposite to each other, the first limiting protrusion 111 abuts against the lamp body 2 when it swings to the left to limit the leftward swing angle of the lamp body 2, and the second limiting protrusion 112 abuts against the lamp body 2 when it swings to the right to limit the rightward swing angle of the lamp body 2. In this way, by limiting the leftward and rightward swing angles of the lamp body 2, it is possible to avoid the leftward and rightward swing angles of the lamp body 2 being too large to reduce the irradiation range.

[0051] In one embodiment, the leftward swing angle and the rightward swing angle of the lamp body 2 are both 20°, so that the light-emitting angle of the lamp body 2 is adjustable while ensuring that the illumination range of the lamp body 2 after the light-emitting angle is adjusted is maximized.

[0052] In other embodiments, the leftward swing angle and the rightward swing angle of the lamp body 2 can be any angle such as 10°, 15°, 18°, 25°, etc., which can be set according to actual needs.

[0053] See also Figure 3 In one embodiment, the mounting base 1 has a support portion 121, and the support portion 121 is arranged around the vertical center line of the lamp body 2;

[0054] Downlights with adjustable light angles also include:

[0055] A rotating ring 3, the rotating ring 3 is rotatably disposed on the support portion 121 around the vertical center line of the lamp body 2, and the rotating ring 3 is disposed around the lamp body 2;

[0056] The two opposite lateral outer sides of the lamp body 2 are pivotally connected to the rotating ring 3, so that the lamp body 2 is indirectly pivotally connected to the mounting base 1. In this way, the rotating ring 3 is supported by the support portion 121, so that the rotating ring 3 is built into the downlight, which can simplify the external structure of the downlight and make the appearance of the downlight more simple and beautiful. At the same time, the rotating ring 3 can be driven to rotate by turning the lamp body 2, thereby driving the lamp body 2 to rotate around its own vertical center line, and supporting manual adjustment of the position of the lamp body 2 relative to the mounting base 1 during installation, which can meet various application scenarios and is more flexible and convenient to use.

[0057] See also Figure 8 and Fig.10 In one embodiment, one of the support portion 121 and the rotating ring 3 is provided with a guide groove 31, which is arranged around the rotation center line of the rotating ring 3, and the other is provided with a guide protrusion 122, which can be slidably matched with the guide groove 31 to guide the rotation of the rotating ring 3, so that the lamp body 2 can rotate more smoothly, avoid jamming, and have a better operating feel.

[0058] See also Figure 8 and Fig.10 In one embodiment, a third limiting protrusion 32 is provided in the guide groove 31, and the third limiting protrusion 32 can abut against the guide protrusion 122 to limit the rotation angle of the rotating ring 3. In this way, when the lamp body 2 rotates clockwise, the guide protrusion 122 slides along the guide groove 31 until the guide protrusion 122 abuts against the third limiting protrusion 32, so as to limit the clockwise rotation of the lamp body 2, thereby limiting the clockwise rotation angle of the lamp body 2. Similarly, when the lamp body 2 rotates counterclockwise, the guide protrusion 122 slides along the guide groove 31 until the guide protrusion 122 abuts against the third limiting protrusion 32, so as to limit the counterclockwise rotation of the lamp body 2, thereby limiting the counterclockwise rotation angle of the lamp body 2.

[0059] In one implementation, the clockwise rotation angle and the counterclockwise rotation angle of the lamp body 2 are both 355°, so as to maximize the clockwise rotation angle and the counterclockwise rotation angle of the lamp body 2 .

[0060] In other embodiments, the clockwise rotation angle and the counterclockwise rotation angle of the lamp body 2 may be set to any angle of 90°, 120°, 180°, 270°, etc., and may be set according to actual needs.

[0061] See also Figure 3 and Fig.10In one embodiment, connecting holes 33 are provided on opposite sides of the rotating ring 3, and the connecting holes 33 pass through the inner and outer side walls of the rotating ring 3;

[0062] The first fasteners 4 are provided on both opposite outer sides of the lamp body 2. The head of the first fastener 4 is located on one side close to the outer wall of the rotating ring 3. The outer diameter of the head of the first fastener 4 is larger than the aperture of the connecting hole 33. The rod of the first fastener 4 is rotatably provided with the connecting hole 33 so that the lamp body 2 can swing left and right relative to the mounting base 1. In this way, the lamp body 2 and the rotating ring 3 can be reliably connected together through the first fastener 4, and the lamp body 2 can swing left and right relative to the rotating ring 3. The connection structure is simple and practical, and the installation is convenient. When the lamp body 2 swings left and right relative to the rotating ring 3, the lamp body 2 swings with the axial center line of the first fastener 4 as the swing center line.

[0063] In one embodiment, the connecting hole 33 includes a first hole segment and a second hole segment, and the first hole segment and the second hole segment are arranged in sequence from the outside to the inside along the radial direction of the rotating ring 3 and are connected. The aperture of the first hole segment is larger than the aperture of the second hole segment. The head of the first fastener 4 is located in the first hole segment, which serves to accommodate the head of the first fastener 4, avoiding the head of the first fastener 4 from being exposed to the rotating ring 3 and occupying too much radial space of the downlight, which is more conducive to the compact structure of the downlight. The rod of the first fastener 4 is clearance-matched with the second hole segment so that the first fastener 4 can swing with the lamp body 2.

[0064] See also Figure 8 In one embodiment, there are multiple support parts 121, which are arranged at intervals around the vertical center line of the lamp body 2, and the rotating ring 3 is placed on top of the multiple support parts 121. Based on the multiple support parts 121 being arranged at intervals, there are heat dissipation gaps between adjacent support parts 121, which can improve the heat dissipation efficiency of the lamp body 2.

[0065] In other embodiments, the support portion 121 may be a ring-shaped structure disposed around the vertical center line of the lamp body 2 .

[0066] See also Figure 3-Figure 5 In one embodiment, the lamp body 2 includes:

[0067] The heat dissipation bottom shell 21, the two lateral opposite outer sides of the heat dissipation bottom shell 21 are both pivotally connected to the mounting base 1, the heat dissipation bottom shell 21 has a receiving groove 211 and a mounting opening, the mounting opening is located on the bottom of the heat dissipation bottom shell 21, and the mounting opening is connected to the receiving groove 211;

[0068] The circuit board 22 is disposed on the bottom wall of the receiving groove 211. The circuit board 22 enters and exits the receiving groove 211 through the installation opening. The circuit board 22 is used to be electrically connected to an external power source;

[0069] LED lamp beads 23, the LED lamp beads 23 are arranged on the circuit board 22, and the LED lamp beads 23 are electrically connected to the circuit board 22;

[0070] The diffusion cover 24 is arranged on the heat dissipation bottom shell 21, and the diffusion cover 24 covers the installation port. The diffusion cover 24 and the LED lamp beads 23 are arranged relative to each other so that the light emitted by the LED lamp beads 23 can be projected to the outside. Since the circuit board 22 is arranged on the bottom wall of the receiving groove 211, the contact area between the circuit board 22 and the heat dissipation bottom shell 21 is maximized, which is conducive to the rapid heat dissipation of the heat generated by the circuit board 22 and the LED lamp beads 23 when they are working, and the heat dissipation is more efficient, ensuring that the circuit board 22 and the LED lamp beads 23 can work normally. At the same time, the diffusion cover 24 can evenly distribute the light emitted by the LED lamp beads 23 to the surrounding environment of the downlight to achieve a better lighting effect.

[0071] See also Fig. 9 In one embodiment, the number of LED lamp beads 23 is multiple rows, and the multiple rows of LED lamp beads 23 are arranged at intervals along the radial direction of the lamp body 2;

[0072] Each row of LED lamp beads 23 includes a plurality of LED lamp beads 23 , and the plurality of LED lamp beads 23 are arranged at intervals around the vertical center line of the lamp body 2 to improve the lighting brightness.

[0073] In one embodiment, among the multiple LED lamp beads 23, at least a portion of the LED lamp beads 23 are RGB lamp beads, and at least a portion of the LED lamp beads 23 are dual-color temperature or multi-color temperature lamp beads. Based on the RGB lamp beads, the RGB lamp beads have 16 million lighting effects, and the controller of the downlight can be used to control the switching of the color and brightness of the RGB lamp beads, so that the downlight has RGB lighting effects, and then the downlight can emit various dynamic and colorful lights, and the lighting effects are richer and more diverse, and different atmospheres can be created in the space to meet different usage requirements. In addition, based on at least a portion of the LED lamp beads 23 being dual-color temperature or multi-color temperature lamp beads, the controller of the downlight can be used to control the dual-color temperature or multi-color temperature lamp beads to switch to different color temperatures. When only the dual-color temperature or multi-color temperature lamp beads are working, the downlight has different color temperature monochrome effects, and when the dual-color temperature or multi-color temperature lamp beads and the RGB lamp beads are working at the same time, the downlight has different color temperature monochrome effects and mixed lighting effects of RGB lighting effects of different colors and brightness, and the lighting effects are more diverse, which can meet different usage requirements.

[0074] In one embodiment, the controller is electrically connected to the circuit board 22 via a power line 5, and the controller is placed outside the downlight to prevent the downlight from shielding the controller's signal.

[0075] In one embodiment, the circuit board 22 is an aluminum substrate, which can quickly dissipate heat from the LED lamp beads 23, thereby further improving the heat dissipation efficiency of the downlight.

[0076] To facilitate the installation of the lamp body 2 and the rotating ring 3, in one embodiment, the mounting base 1 includes a back cover 11 and a face ring 12, and the back cover 11 and the face ring 12 are arranged in sequence from top to bottom along the downlight, and the back cover 11 and the face ring 12 are fixed together by a second fastener 15, and the back cover 11 and the face ring 12 enclose the above-mentioned mounting cavity 13, and the face ring 12 has the above-mentioned light-transmitting hole.
