[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0044] Such as Figures 1 to 3 And Figure 7As shown in the figure, the present application provides a spot light, which includes a cup base 1, a lamp cup 2, and a circumferential angle limiting structure. Among them, the cup base 1 is the base for components such as the lamp cup 2 and the reflector cup 6. The lamp cup 2 is the outer shell at the front end of the spot light. The lamp cup 2 is coaxially arranged with the cup base 1 and is rotatably connected to the cup base 1 around the axis of the cup base 1. By rotating the lamp cup 2, the circumferential angle of the lamp cup 2 relative to the cup base 1 can be adjusted. In order to fix the lamp cup 2 at any angle, the circumferential angle limiting structure is introduced in the spot light of the present application. This structure includes a limiting member 3 and a plurality of limiting grooves 4 that are equally or unequally spaced around the axis of the cup base 1. When the limiting member 3 is engaged with any one of the limiting grooves 4, the circumferential angle of the lamp cup 2 relative to the cup base 1 is firmly locked. Through the engagement of the limiting member 3 and the limiting groove 4, the rotation angle of the lamp cup 2 is fixed.

[0045] In the specific structural layout, the limiting groove 4 can be set at an appropriate position on the cup base 1, and the limiting member 3 is fixedly connected to the corresponding part of the lamp cup 2 as a matching component; or, the limiting groove 4 is opened on the lamp cup 2, and correspondingly, the limiting member 3 is installed on the cup base 1 to limit the rotation angle of the lamp cup 2. The specific layout method can select the most suitable scheme according to actual production requirements and cost considerations.

[0046] As Figure 2 and Figure 3 shown in the figure, in an embodiment of the present application, the spot light of the present application further includes a lamp base 5. The lamp base 5 is the base at the rear end of the spot light and is used to carry components such as a light-emitting component 8 and a radiator 9. The lamp base 5 is coaxially arranged with the cup base 1 and is radially hinged to the cup base 1 around the cup base 1, so that the lamp base 5 and the cup base 1 can swing relative to each other, thereby adjusting the irradiation range and irradiation inclination angle of the spot light.

[0047] As Figure 6 shown in the figure, in an embodiment of the present application, a first sunk platform 21 is provided on the lamp cup 2, and a second sunk platform 51 is provided on the lamp base 5. The first sunk platform 21 and the second sunk platform 51 are arranged facing each other, and the first sunk platform 21 and the second sunk platform 51 form an avoidance space when the lamp base 5 and the cup base 1 are hinged. When the lamp base 5 and the cup base 1 swing relative to each other, the avoidance space can prevent interference between the lamp base 5 and the cup base 1 and affect the normal swing of the lamp base 5 and the cup base 1.

[0048] As Figures 1 to 3 shown in the figure, in an embodiment of the present application, the lamp base 5 is provided with a lug 52. The number of lugs 52 is one, or two that are oppositely arranged along the radial direction of the lamp base 5. And the cup base 1 is correspondingly provided with a hinge hole. When the lamp base 5 is connected to the cup base 1, the lug 52 extends into the cup base 1 and aligns the lug 52 with the hinge hole. Through a hinge member connected to the lug 52, such as a screw, a pin, etc., the hinge connection with the hinge hole is realized, so that the lamp base 5 and the cup base 1 can swing relative to each other.

[0049] As Figure 5 shown, in an embodiment of the present application, the cup holder 1 is provided with first elastic claw petals 11, and the first elastic claw petals 11 are arranged along the circumferential direction of the cup holder 1. In this embodiment, the limiting member 3 is connected to the first elastic claw petals 11. Through the elasticity of the first elastic claw petals 11, the limiting member 3 can be pressed against the limiting groove 4, so that the limiting member 3 is engaged with the limiting groove 4, and the limiting member 3 can also elastically yield when the limiting groove 4 with which the limiting member 3 is engaged is switched.

[0050] In an embodiment of the present application, the limiting member 3 includes a housing, a spring, and a ball. The housing is installed on the first elastic claw petals 11, the spring is placed inside the housing, one end of the spring is connected to the inner side of the housing, and the other end of the spring is connected to the ball. Through the elastic force of the spring, a certain pre-tightening force is given to the ball. Under the action of the pre-tightening force, the engagement between the ball and the limiting groove 4 can be maintained. When the lamp cup 2 is rotated, the acting force is greater than the pre-tightening force, and the spring is compressed, so that the ball switches to the next limiting groove 4. The switching process is also accompanied by a "click" sound, enhancing the feedback of the angle switching experience.

[0051] As Figure 5 shown, in an embodiment of the present application, the cup holder 1 is further provided with second elastic claw petals 12. One end of the second elastic claw petals 12 is provided with a barb 13, and a shoulder 22 is provided on the inner wall of the lamp cup 2. When the lamp cup 2 is installed and connected to the cup holder 1, the barb 13 will naturally engage with the shoulder 22, so that between the cup holder 1 and the lamp cup 2, both the free rotation between the cup holder 1 and the lamp cup 2 can be realized, and the risk of accidental detachment between the cup holder 1 and the lamp cup 2 during normal use is effectively prevented.

[0052] As Figure 1 shown, in an embodiment of the present application, the spot lamp of the present application further includes a reflector cup 6 and a ferrule 7. The reflector cup 6 is installed on the lamp cup 2, and the reflector cup 6 is used to reflect the light emitted by the light-emitting component 8, ensuring that the light can be projected uniformly and intensively in a predetermined direction, thereby improving the lighting effect. A connecting thread is provided on the outer side surface of the lamp cup 2. By rotating the ferrule 7, it is tightly engaged with the connecting thread of the lamp cup 2, so as to realize the ferrule and fixation of the reflector cup 6.

[0053] As Figure 2 and Figure 3As shown, in an embodiment of the present application, the light-emitting component 8 includes a lamp core 81, a lens 82, and a condenser cup 83. The lamp core 81 is used to convert electrical energy into light energy, and the lamp core 81 is installed on the lamp base 5. The condenser cup 83 can effectively converge the light emitted by the lamp core 81, reduce the scattering and waste of light energy, enhance the directivity and concentration of the light, thereby improving the lighting efficiency. The lamp core 81 is provided at the light-gathering port of the condenser cup 83, and the lens 82 is provided at the emission port of the condenser cup 83. The lens 82 can not only further fine-tune and optimize the light converged by the condenser cup 83, such as adjusting the spot shape, controlling the light diffusion angle, etc., but also protect the lamp core 81 from the influence of the external environment, ensuring the long-term stable operation of the light-emitting component 8.

[0054] As Figure 2 and Figure 3 As shown, in an embodiment of the present application, the lens 82 includes a conical mirror body. The small end of the conical mirror body faces the lamp core 81, and the large end of the conical mirror body faces the outside; the small end of the conical mirror body has a light-gathering blind hole, and the bottom of the light-gathering blind hole is a first light-gathering curved surface. The first light-gathering curved surface faces the lamp core 81 and protrudes towards the lamp core 81. Under the light-gathering effect of the first light-gathering curved surface, more light is converged to the large end of the conical mirror body. The large end of the conical mirror body has a second light-gathering curved surface, and the second light-gathering curved surface protrudes towards the outside. The second light-gathering curved surface then projects the light to a wider range.

[0055] As Figure 1 and Figure 7 As shown, in an embodiment of the present application, it further includes a radiator 9. The radiator 9 is sleeved outside the lamp base 5 and is in contact with the lamp base 5. Using the principle of heat conduction, the heat generated by the light-emitting component 8 during operation is conducted to the radiator 9 and then diffused through the air. The radiator 9 is made of a material with high thermal conductivity, such as aluminum alloy or copper alloy. These materials not only have good thermal conductivity but also excellent mechanical strength and corrosion resistance, and can maintain stable heat dissipation performance under complex and changeable environmental conditions. In addition, the surface of the radiator 9 can be further processed into various heat dissipation structures, such as fins, ribs, or microchannels, etc., to increase the heat dissipation area, promote air convection, thereby accelerating the dissipation of heat and reducing the overall temperature of the lamp system.

[0056] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
