For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention provides Figure 1-Figure 6 A lamp with adjustable light output angle as shown in , comprising:

[0029] A lamp housing 101, wherein an annular groove 1011 is provided on the top of the lamp housing 101, two symmetrical mounting openings 1012 are provided on the side wall of the lamp housing 101, and a snap ring 1013 is provided on the bottom of the lamp housing 101;

[0030] The rotating bracket 102 is arranged in the annular groove 1011. The rotating bracket 102 includes a mounting ring 1021, a mounting plate 1022, a lifting ring 1023 and a connecting plate 1024 which are designed as an integral part. A horizontal baffle 1025 is fixed on the top of the mounting ring 1021.

[0031] The tilt bracket 103 is arranged on the top of the horizontal baffle 1025. A heat dissipation hole 1031 is arranged at the center of the tilt bracket 103. A connection hole 1032 is arranged at one end of the tilt bracket 103. The other end of the tilt bracket 103 is arranged to be tilted upward, and a mounting plate 2 1033 is arranged at the end in the vertical direction. A connecting plate 2 1034 is arranged at the bottom of the tilt bracket 103.

[0032] Radiator 104, radiator 104 is arranged on the top of the inclined bracket 103, a radiator top cover plate 1041 is arranged on the top of the radiator 104, a radiator side cover plate 1042 is arranged on one side of the radiator 104, and the radiator 104 is connected to the hanging ring 1023 through a coil spring;

[0033] The tilt arm 105 includes a swing arm 1051 and a mounting seat 1052 which are integrally formed. One end of the swing arm 1051 is connected to the radiator 104 via a pin. The mounting seat 1052 is movably connected to the connecting plate 1024. The mounting seat 1052 is threadedly connected to the mounting ring 1021 via an adjusting bolt 1056.

[0034] For example, see Figure 1As shown, it also includes a height adjustment component 106 arranged in the installation port 1012, and the height adjustment component 106 includes a third installation plate 1061, a limit block 1062 and a second adjustment bolt 1063, the second adjustment bolt 1063 is movably connected to the third installation plate 1061, and the limit block 1062 is threadedly connected to the second adjustment bolt 1063.

[0035] In this technical solution, the mounting plate three 1061 is fixedly connected to the lamp housing 101 by rivets. The mounting plate three 1061 is an arc-shaped plate, which can better fit with the lamp housing 101. A groove is provided on the outer side of the mounting plate three 1061. The limit block 1062 and the adjusting bolt two 1063 are both located in the groove, which is beneficial to ensure the beautiful appearance of the lamp housing 101. When the adjusting bolt two 1063 is turned, the limit block 1062 can move along the adjusting bolt two 1063, so that the distance between the limit block 1062 and the retaining ring 1013 can be adjusted, so that the limit block 1062 fits with the top of the ceiling, and the retaining ring 1013 fits with the bottom of the ceiling, so that the lamp can be installed on ceilings of different thicknesses, thereby improving applicability.

[0036] For example, see Figure 2 As shown, the optical assembly 107 is also provided at the bottom of the heat sink 104 . The optical assembly 107 includes a light source module, a lens and an aperture. A lens hood 1071 is fixed to one side of the optical assembly 107 .

[0037] In this technical solution, the light source module emits light, which is gathered and constrained by the lens and aperture to form a relatively parallel light beam, thereby improving the lighting effect. The lens hood 1071 can protect the optical component 107 and prevent it from colliding with the rotating bracket 102 when adjusting the light output angle. In addition, the optical component 107 is arranged at the bottom of the radiator 104, so that the heat generated by the optical component 107 during operation can be transferred to the radiator 104 in time, ensuring that the optical component 107 will not be damaged due to excessive temperature.

[0038] For example, see Figure 1-Figure 2 As shown, it also includes a cable assembly 108 arranged on one side of the radiator side cover 1042, the cable assembly 108 includes a cable 1081, a connector 1082 and a plug connector 1083, the connector 1082 is arranged at one end of the cable 1081 and is fixedly connected to the radiator side cover 1042, and the plug connector 1083 is arranged at the other end of the cable 1081 and is electrically connected to the junction box.

[0039] In this technical solution, the external power source is connected through the cable assembly 108 to provide power support for the use of the lamp.

[0040] For example, see Figure 1As shown, it also includes a ground wire 109 arranged on the radiator top cover plate 1041. The ground wire 109 includes a wire 1091 and a wiring harness terminal 1092 fixed at one end of the wire 1091. The wiring harness terminal 1092 is fixedly connected to the radiator top cover plate 1041 through a rivet.

[0041] In this technical solution, by fixedly connecting the wiring harness terminal 1092 with the radiator top cover plate 1041, the voltage of the lamp housing can be effectively reduced, so that the lamp is at a safe potential, preventing the lamp from malfunctioning due to excessive voltage and protecting the normal operation of the lamp. When the power system fails or the lamp leaks electricity, the ground wire 109 can quickly lead the current into the ground, reducing the probability of current passing through the human body, preventing electric shock accidents, and protecting personal safety.

[0042] For example, see Figure 4 As shown, the cross section of the horizontal baffle 1025 is a U-shaped structure, and the outer edges of the U-shaped grooves of the horizontal baffle 1025 protrude upward to the same horizontal height.

[0043] In this technical solution, the horizontal baffle 1025 provides support for the tilting bracket 103 and also increases the horizontal height of the tilting bracket 103, so that there is a gap between the tilting bracket 103 and the rotating bracket 102, preventing the protrusion on the top of the rotating bracket 102 from affecting the horizontal installation of the tilting bracket 103.

[0044] For example, see Figure 2 and Figure 5 As shown, a protective plate 1035 is provided on one side of the tilt bracket 103 , and both ends of the protective plate 1035 are fixedly connected to the second connecting plate 1034 by rivets.

[0045] In this technical solution, the protective plate 1035 is a curved plate, which can better fit the heat sink 104 and better shield the optical component 107 to prevent it from being damaged by collision.

[0046] For example, see Figure 6 As shown, a strip hole 1053 is provided at one end of the swing arm 1051, a second connection hole 1054 is provided on one side of the mounting seat 1052 and an adjustment hole 1055 is provided at the bottom, the swing arm 1051 and the mounting seat 1052 are both inclined, and the angle between the swing arm 1051 and the mounting seat 1052 is an acute angle.

[0047] In this technical solution, a bolt passes through a second connecting hole 1054 to connect the mounting base 1052 to the connecting plate 1024, an adjusting bolt 1056 passes through an adjusting hole 1055 and is threadedly connected to the mounting ring 1021, and by turning the adjusting bolt 1056 forward or reversely, one end of the mounting base 1052 can be driven to rise or fall, and then the connection between the mounting base 1052 and the connecting plate 1024 can be used as a fulcrum to drive the swing arm 1051 to move, and finally the heat sink 104 and the optical component 107 are driven to tilt to a specified angle through the swing arm 1051, thereby realizing continuous stepless adjustment of the light output angle of the lamp in the vertical direction within the range of 0° to 45°.

[0048] Working principle: When installing the lamp with adjustable light output angle, first press the retaining ring 1013 against the lower surface of the ceiling, then open the limit block 1062, turn the adjusting bolt 1063 to adjust the height of the limit block 1062, until the limit block 1062 is pressed against the upper surface of the ceiling. At this time, the installation of the lamp is completed, and then turn the adjusting bolt 1056 to drive one end of the mounting base 1052 to move up and down, thereby driving the swing arm 1051 to move, and the swing arm 1051 drives the radiator 104 and the optical component 107 to tilt at a specified angle, thereby realizing continuous stepless adjustment of the vertical light output angle of the lamp within the range of 0° to 45°, and then rotate the mounting plate 1022, thereby driving the radiator 104 and the optical component 107 to rotate at a specified angle, thereby realizing 360° adjustment of the horizontal light output direction of the lamp. The lamp with adjustable light output angle is of advanced design, compact structure and easy to use. By screwing the adjusting bolt 1056 to adjust the distance between the mounting base 1052 and the rotating bracket 102, the inclination angle of the tilt arm 105 can be changed, thereby driving the radiator 104 and the optical component 107 to tilt, thereby realizing stepless adjustment of the light output angle of the lamp within the range of 0° to 45° in the vertical direction. By rotating the rotating bracket 102, the radiator 104 and the optical component 107 can be driven to rotate together, thereby realizing 360° adjustment of the light output direction of the lamp in the horizontal direction, thereby greatly improving the applicability of the lamp, being able to meet the different needs of users and reducing the user's usage cost.
