Description

Technical Field

[0001] The present application relates to the technical field of lighting equipment, and in particular to a downlight with adjustable angle. Background Art

[0002] In the field of modern lighting, downlights, as a commonly used lighting equipment, are widely used in various indoor places, such as homes, offices, shopping malls, hotels, etc. However, traditional downlights have obvious deficiencies in angle adjustment. On the one hand, the angle adjustment function of many existing downlights is relatively limited, and they can often only be adjusted within a few fixed angle ranges, which cannot meet the user's needs for diversified lighting angles in different scenarios. For example, when displaying artworks, highlighting specific decorative areas, or providing precise lighting for specific work areas, traditional downlights are difficult to flexibly adjust the angle to achieve the best lighting effect. On the other hand, although some downlights claim to have angle adjustment functions, the adjustment process is complicated and cumbersome, and requires the use of professional tools or complex operating steps, which brings great inconvenience to users' actual use. Moreover, this complex adjustment method is also prone to inaccurate angle adjustment, affecting the lighting quality.

[0003] With respect to the above-mentioned related technologies, the inventors found the following defects:

[0004] (1) The angle adjustment function of existing downlights is relatively limited. They can only be adjusted within a few fixed angles, which often makes users feel restricted during use. Especially in different scenarios, such as the living room and bedroom of a home, or the exhibition area and office environment of a commercial space, users have different needs for lighting angles. It is often necessary to flexibly adjust the light direction according to the specific activities, atmosphere or functional areas to achieve the best lighting effect;

[0005] (2) It is difficult to dissipate heat inside the lamp tube, which can easily lead to dangerous accidents. This is a problem that cannot be ignored in the design and use of downlights. With the widespread use of high-power light sources such as LEDs, their heat generation has increased significantly. If the heat dissipation design is not reasonable, it may cause the internal temperature of the lamp to be too high, which in turn may cause a series of safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The embodiment of the present application discloses a downlight with adjustable angle. Figure 1 As shown, the radiator 1 includes a plastic back cover 2 fixedly connected to the top of the radiator 1. A rotating assembly 3 is fixedly connected to one side of the plastic back cover 2. A plastic connecting ring 4 is rotatably connected to one side of the rotating assembly 3. The rotating assembly 3 and the plastic back cover 2 are arranged to achieve a rotating effect during use, allowing users to easily adjust the downlight's illumination angle within a wide range. Whether used for accent lighting, creating an atmosphere, or meeting the needs of a specific work area, the user can quickly find the most suitable angle, greatly improving the applicability of the downlight and achieving the desired angle adjustment effect. A quick-release protective coil 5 is threadedly connected to the top of the plastic connecting ring 4. The arrangement of the radiator 1 and the quick-release protective coil 5 ensures safe heat dissipation during use. The various components of the entire downlight are primarily connected by threaded connections, making the installation process simple and quick, without the need for complex tools or professional skills. The radiator 1 also provides heat dissipation and protection for the interior of the downlight, preventing the occurrence of danger, thereby achieving safe heat dissipation. A positioning media 6 is fixedly connected to the top of the quick-release protective coil 5. A cross-head self-tapping screw 7 is threadedly connected to one side of the radiator 1. A chip holder 8 is threadedly connected to the side of the cross-head self-tapping screw 7.

[0024] See also Figure 2One side of the pressing piece 12 is fixedly connected to the rear lamp tube 14, and the top of the rear lamp tube 14 is fixedly connected to the plastic ceiling cover 15. The purpose of this design is to make the installation and use of the entire lamp more reliable through this structure, avoiding the falling off caused by vibration, impact or other external factors in daily use. The fixed connection between the pressing piece 12 and the rear lamp tube 14 forms a stable foundation. This connection method can effectively disperse the weight of the lamp itself and the vibration generated in daily use, ensure the stability of the lamp during use, and reduce the risk of accidental falling off.

[0025] See also Figure 3 The top of the pressing piece 12 is threaded with a cross-head round screw 13, and one side of the top of the pressing piece 12 is threaded with a cross-head round self-tapping screw 7. The purpose of this design is that the cross-head round screw 13 is designed to make it easier for users to rotate and tighten it during installation. The cross-shaped head provides a larger contact area, which can effectively transmit torque and reduce the possibility of slippage.

[0026] See also Figure 2 The top of the positioning medium 6 is threaded with a hexagonal hollow screw 11, and a pressure piece 12 is threaded onto one side of the hexagonal hollow screw 11. This design provides a strong structural fixing solution, ensuring that the pressure piece 12 remains secure during use and prevents any loosening or displacement. The design features of the hexagonal hollow screw 11 enable it to provide higher torque and greater stability during the fixing process. Because the hexagonal head allows for more effective force application with tools such as wrenches, users can easily tighten it to the positioning medium 6.

[0027] See also Figure 3 One side of the chip holder 8 is threaded with a cross countersunk screw 9, and one side of the cross countersunk screw 9 is threaded with a plastic speaker ring 10. The purpose of this design is to reliably fix the plastic speaker ring 10 through the cross countersunk screw 9, thereby ensuring the stability and safety of the overall structure. The use of the cross countersunk screw 9 provides a convenient and efficient fixing method. Its countersunk design allows the screw to be completely embedded in the surface of the chip holder 8 when screwed in, avoiding interference caused by the protruding screw head. The material and shape of the plastic speaker ring 10 itself can effectively resist the influence of environmental factors such as moisture and temperature changes, ensuring that it can maintain its shape and function under various working conditions.

[0028] See also Figure 2The rotating assembly 3 includes a plastic hanging arm 301 fixedly connected to one side of the plastic back cover 2. One side of the plastic hanging arm 301 is threadedly connected to a cross round head connecting screw 302, and the other side of the plastic hanging arm 301 is threadedly connected to a lock nut 303. The purpose of this design is to adjust the rotation of the plastic back cover 2 through the plastic hanging arm 301, thereby achieving the effect of adjusting the rotation.

[0029] See also Figure 3 Chip holder 8 has cooling holes inside and four screw holes on its surface. These holes promote air circulation, helping to reduce the temperature inside the holder and ensure the chip remains within the ideal operating temperature range. This is crucial for improving the performance and extending the life of electronic devices, as excessive temperatures can affect chip efficiency and even cause malfunction or damage.

[0030] The implementation principle of an angle-adjustable downlight in an embodiment of the present application is as follows: the plastic boom 301 is fixed by a cross round head connecting screw 302, and the plastic back cover 2 is connected to the rear lamp tube 14. The position and angle of the rear lamp tube 14 can be adjusted and controlled according to actual conditions. The chip bracket 8 is fixed to the inside of the radiator 1 by a cross round head self-tapping screw 7. The radiator 1 can dissipate heat to the inside of the downlight to avoid damage to the inside of the device. The quick-install protective coil 5 can fix and comb the cables, etc. The positioning medium 6 and the quick-install protective coil 5 are fixed by a hexagonal hollow screw 11, the plastic connecting ring 4 is connected by a cross round head self-tapping screw 7, and the entire device is fixed by a plastic ceiling cover 15.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
