Technical Field
[0001] This utility model belongs to the field of spotlight technology, and specifically relates to a spotlight with an adjustable emission angle. Background Technology
[0002] Spotlights are a typical modern style of lighting without a main light or a fixed scale. They can create an indoor lighting atmosphere. If a row of spotlights is combined, the light can change into wonderful patterns. Because spotlights can be freely adjusted in angle, the combined lighting effect is also ever-changing. Spotlights have soft, elegant and luxurious light, and they can also provide local lighting to enhance the atmosphere.
[0003] A traditional spotlight includes: a heat sink, an LED light source, a light source mounting bracket, a lens, a lens mounting bracket, a connecting ring, a mounting ring, and a reflector. One end of the heat sink has heat dissipation fins for heat dissipation, and the other end has a light source receiving slot. The light source mounting bracket fixes the LED light source in the light source receiving slot. The lens mounting bracket mounts the lens in the light source mounting bracket. The connecting ring is rotatably mounted at the opening of the light source receiving slot. The mounting ring is fitted onto the connecting ring. The reflector is snapped into the inner wall of the mounting ring. When the heat sink rotates relative to the connecting ring, the light emission angle of the spotlight changes.
[0004] However, firstly, the installation of the lamp is complicated due to the large number of components; secondly, the large number of components installed on the heat sink makes the heat sink bulky, and rotating the heat sink near the wall on the ceiling is easily blocked by the wall; thirdly, the heat sink needs to rotate relative to the connecting ring, and one side of the connecting ring needs to be designed with a rotation clearance notch to provide space for the heat sink to rotate. However, the existence of the clearance notch will cause the light emitted by the LED light source to leak out to the outside from the clearance notch, which will further make the light output of the spotlight uneven and affect the user experience. Utility Model Content
[0005] The main objective of this invention is to provide a spotlight with an adjustable emission angle. By reducing the number of components, such as the light source mounting bracket and connecting ring, compared to traditional spotlights, the number of components in the lamp is reduced, thus simplifying installation. Secondly, the reduced number of components mounted on the heat sink allows for a smaller heat sink, reducing the likelihood of the heat sink being obstructed by the wall when rotating it near the ceiling. Finally, the notch in the heat sink facing the mounting ring and the protruding shielding edge on the opposite side of the notch effectively block the gap created when the heat sink rotates relative to the mounting ring, preventing light emitted from the LED light source from escaping through the gap and affecting the uniformity of the light output, thereby improving the user experience.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] An adjustable-angle spotlight includes: a heat sink, an LED light source, a lens bracket, a lens, a limiting ring, a mounting surface ring, and a reflector. One end of the heat sink is recessed inward to form a light source receiving groove. The lens bracket is fixed to the bottom of the light source receiving groove, and the LED light source is pressed against the bottom of the light source receiving groove. The lens is installed inside the lens bracket. The limiting ring is installed at the opening of the light source receiving groove to press the lens against the lens bracket. The mounting surface ring is pivotally hinged to one end of the heat sink. One side of the mounting surface ring has a clearance notch. One end of the heat sink extends towards the inner wall of the mounting surface ring at both the position of the clearance notch and the position on the opposite side of the clearance notch to form a blocking protrusion. The blocking protrusion is used to block the gap between the mounting surface ring and the heat sink. The reflector is disposed inside the mounting surface ring and is integrally formed with the mounting surface ring.
[0008] As a preferred embodiment of an adjustable-angle spotlight, the adjustable-angle spotlight further includes: a mounting spring; the mounting surface ring has a reinforcing rib on its inner wall corresponding to the position of the mounting spring, and the rivet passes through the mounting spring and extends into the mounting surface ring located at the position of the reinforcing rib for riveting.
[0009] As a preferred embodiment of an adjustable-angle spotlight, the mounting spring has hollowed-out sides to form abutment springs. After the mounting spring is fixed to the mounting surface ring, the abutment springs abut against the outer side of the mounting surface ring to restrict the rotation of the mounting spring.
[0010] As a preferred embodiment of an adjustable-angle spotlight, the two sides of the heat sink extend toward the position of the reinforcing rib to form a hinge arm. The reinforcing rib is provided with a hinge groove, and the hinge arm is embedded in the hinge groove. The fixing screw passes through the mounting surface ring and extends into the hinge arm after passing outside the mounting surface ring at the position of the hinge groove.
[0011] As a preferred embodiment of an adjustable emission angle spotlight, the outer side of the limiting ring is provided with an external thread, and the opening of the light source receiving groove is provided with an internal thread. The external thread is screwed into the internal thread, thereby installing the limiting ring at the opening of the light source receiving groove.
[0012] As a preferred embodiment of an adjustable-angle spotlight, the inner wall of the limiting ring is provided with a first abutting protrusion near the lens. The edge of the lens near the limiting ring extends outward to form an abutting protrusion. The first abutting protrusion abuts against the abutting protrusion, pressing the abutting protrusion tightly against the lens bracket.
[0013] As a preferred embodiment of an adjustable emission angle spotlight, the adjustable emission angle spotlight further includes: a beam shaping component; the inner wall of the limiting ring is provided with a second abutment protrusion near the first abutment protrusion, the second abutment protrusion presses the beam shaping component against the lens, and the beam shaping component is used to change the type of light emitted by the lamp.
[0014] As a preferred embodiment of an adjustable-angle spotlight, the lens bracket has hollowed-out elastic locking grooves on both sides, and the lens has locking protrusions on both sides, which engage with the elastic locking grooves to restrict the rotation of the lens.
[0015] As a preferred embodiment of an adjustable-angle spotlight, the heat sink has a wire hole on its side, which is connected to the light source receiving slot. An external power cord passes through the wire hole and is electrically connected to the LED light source.
[0016] As a preferred embodiment of an adjustable-angle spotlight, the other end of the radiator is recessed inward to form a heat dissipation section, which is used to increase the heat dissipation area of the radiator.
[0017] As a preferred embodiment of an adjustable-angle spotlight, the lampshade is horn-shaped.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides an adjustable emission angle spotlight, including: a heat sink, an LED light source, a lens bracket, a lens, a limiting ring, a mounting surface ring, and a reflector. One end of the heat sink is recessed inward to form a light source receiving groove.

The lens is installed in the lens bracket. The limiting ring is installed at the opening of the light source receiving groove to press the lens against the lens bracket. The mounting surface ring is pivotally hinged to one end of the heat sink. One side of the mounting surface ring has a clearance notch. One end of the heat sink extends towards the inner wall of the mounting surface ring at the position of the clearance notch and at the position on the opposite side of the clearance notch to form a blocking protrusion. The blocking protrusion is used to block the gap between the mounting surface ring and the heat sink. The reflector is disposed inside the mounting surface ring and is integrally formed with the mounting surface ring. By adopting the above solution, the number of components in the lamp is reduced by eliminating the light source mounting bracket and connecting ring compared to traditional spotlights, thus reducing the complexity of installation. Secondly, the reduction in components mounted on the heat sink reduces its size, thereby decreasing the likelihood of the heat sink being obstructed by the wall when rotating it near the ceiling. Finally, the protruding shielding edge extending from the notch facing the mounting ring and the opposite side of the notch can block the gaps created when the heat sink rotates relative to the mounting ring, preventing light emitted by the LED light source from escaping through these gaps and affecting the uniformity of light output, thereby improving the user experience.

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Spotlights are a typical modern style of lighting without a main light or a fixed scale. They can create an indoor lighting atmosphere. If a row of spotlights is combined, the light can change into wonderful patterns. Because spotlights can be freely adjusted in angle, the combined lighting effect is also ever-changing. Spotlights have soft, elegant and luxurious light, and they can also provide local lighting to enhance the atmosphere.
[0033] A traditional spotlight includes: a heat sink, an LED light source, a light source mounting bracket, a lens, a lens mounting bracket, a connecting ring, a mounting ring, and a reflector. One end of the heat sink has heat dissipation fins for heat dissipation, and the other end has a light source receiving slot. The light source mounting bracket fixes the LED light source in the light source receiving slot. The lens mounting bracket mounts the lens in the light source mounting bracket. The connecting ring is rotatably mounted at the opening of the light source receiving slot. The mounting ring is fitted onto the connecting ring. The reflector is snapped into the inner wall of the mounting ring. When the heat sink rotates relative to the connecting ring, the light emission angle of the spotlight changes.
[0034] However, firstly, the installation of the lamp is complicated due to the large number of components; secondly, the large number of components installed on the heat sink makes the heat sink bulky, and rotating the heat sink near the wall on the ceiling is easily blocked by the wall; thirdly, the heat sink needs to rotate relative to the connecting ring, and one side of the connecting ring needs to be designed with a rotation clearance notch to provide space for the heat sink to rotate. However, the existence of the clearance notch will cause the light emitted by the LED light source to leak out to the outside from the clearance notch, which will further make the light output of the spotlight uneven and affect the user experience.
[0035] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides an adjustable emission angle spotlight, which includes: a heat sink 10, an LED light source 20, a lens bracket 30, a lens 40, a limiting ring 50, a mounting surface ring 60, a reflector 70, a mounting spring 80, and a beam shaping component 90. One end of the heat sink 10 is recessed inward to form a light source receiving groove 11. After the lens bracket 30 is fixed to the bottom of the light source receiving groove 11, the LED light source 20 is abutted against the bottom of the light source receiving groove 11. The lens 40 is installed in the lens bracket 30. The limiting ring 50 is installed at the opening of the light source receiving groove 11 to press the lens 40 tightly against the lens bracket 30. The beam shaping component 90 is sandwiched between the lens 40 and the limiting ring 50. The mounting surface ring 60 is pivotally hinged to one end of the heat sink 10. The mounting spring 80 is mounted on both sides of the mounting surface ring 60. One side of the mounting surface ring 60 is provided with a clearance notch 61. One end of the heat sink 10 extends towards the inner wall of the mounting surface ring 60 at the position of the clearance notch 61 and at the position on the opposite side of the clearance notch 61 to form a blocking protrusion 12. The blocking protrusion 12 is used to block the gap between the mounting surface ring 60 and the heat sink 10. The reflector cup 70 is disposed inside the mounting surface ring 60 and is integrally formed with the mounting surface ring 60.
[0036] In this utility model, by adopting the above-mentioned solution, the number of components in the lamp is reduced by decreasing the number of light source mounting brackets and connecting rings compared to traditional spotlights, thus reducing the complexity of installation. Secondly, due to the reduction in the number of components installed on the heat sink 10, the volume of the heat sink 10 is reduced, thereby reducing the possibility of the heat sink 10 being obstructed by the wall when rotating it near the wall on the ceiling. Finally, since the heat sink 10 extends the blocking protrusion 12 from the clearance notch 61 of the mounting ring 60 and from the opposite side of the clearance notch 61, the blocking protrusion 12 can block the gap caused by the rotation of the heat sink 10 relative to the mounting ring 60, preventing the light emitted by the LED light source 20 from shining out of the gap and affecting the uniformity of the light output of the lamp, thereby improving the user experience.
[0037] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in order to stably install the mounting spring 80, the mounting surface ring 60 is provided with a reinforcing rib 62 on the inner wall corresponding to the position of the mounting spring 80. After the rivet passes through the mounting spring 80, it extends into the mounting surface ring 60 located at the position of the reinforcing rib 62 for riveting, thereby stably fixing the mounting spring 80 to both sides outside the mounting surface ring 60.
[0038] To prevent the mounting spring 80 from rotating on its own, the two sides of the mounting spring 80 are hollowed out to form abutment springs 81. After the mounting spring 80 is fixed to the mounting surface ring 60, the abutment springs 81 abut against the outer side of the mounting surface ring 60 to restrict the rotation of the mounting spring 80 relative to the mounting surface ring 60.
[0039] To install the mounting ring 60, the two sides of the radiator 10 extend towards the reinforcing rib 62 to form hinge arms 13. The reinforcing rib 62 is provided with a hinge groove 621. The hinge arms 13 are embedded in the hinge groove 621. The fixing screw passes through the mounting ring 60 and extends into the hinge arm 13 at the position of the hinge groove 621 on the outside of the mounting ring 60, thereby making the mounting ring 60 pivotally hinged to one end of the radiator 10.
[0040] In order to install the limiting ring 50, the outer side of the limiting ring 50 is provided with an external thread (not shown), and the opening of the light source receiving groove 11 is provided with an internal thread (not shown). The external thread (not shown) is screwed into the internal thread (not shown), thereby installing the limiting ring 50 at the opening of the light source receiving groove 11.
[0041] In order to press the lens 40 against the lens holder 30, the inner wall of the limiting ring 50 is provided with a first abutment 51 near the lens 40. The edge of the lens 40 near the limiting ring 50 extends outward to form an abutment convex edge 41. The first abutment 51 abuts against the abutment convex edge 41, thereby pressing the abutment convex edge 41 against the lens holder 30.
[0042] In order to install the beam shaping component 90, the inner wall of the limiting ring 50 is provided with a second abutment protrusion 52 near the first abutment protrusion 51. The second abutment protrusion 52 presses the beam shaping component 90 against the lens 40. The beam shaping component 90 is used to change the type of light emitted by the lamp. In this utility model, the beam shaping component 90 can be a grid, a honeycomb mesh, a filter, or a light guide plate, or it can be a light enhancement film, a diffusion film, or a prism mold. The beam shaping component 90 only needs to be able to change the type of light emitted by the lamp. This utility model does not limit this.
[0043] To further secure the lens 40, the lens bracket 30 has hollowed-out elastic locking grooves 31 on both sides, and locking protrusions 42 are provided on both sides of the lens 40. The locking protrusions 42 engage with the elastic locking grooves 31 to restrict the rotation of the lens 40 and further secure the lens 40 to the lens bracket 30.
[0044] In order to supply power to the LED light source 20, the heat sink 10 has a wire hole 14 on its side. The wire hole 14 is connected to the light source receiving slot 11. The external power cable passes through the wire hole 14 and is electrically connected to the LED light source 20, thereby supplying power to the LED light source 20.
[0045] To increase the heat dissipation capacity of the radiator 10, the other end of the radiator 10 is recessed inward to form a heat dissipation section 15. The heat dissipation section 15 is used to increase the heat dissipation area of the radiator 10. Compared with the traditional radiator 10 which extends outward to form heat dissipation fins, the height of the radiator 10 is further reduced, thereby further reducing the possibility that the radiator 10 is easily blocked by the wall when rotating it near the wall on the ceiling. This expands the application scenarios of the adjustable-angle spotlight and is conducive to the promotion of the adjustable-angle spotlight.
[0046] The present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments can be made without departing from the principles and spirit of the present invention, and these changes still fall within the protection scope of the present invention.
