Description

Technical Field

[0001] This utility model belongs to the field of downlight technology, and in particular relates to a downlight with adjustable lighting direction. Background Technology

[0002] A downlight is a type of lighting fixture that is embedded in the ceiling and emits light downwards. It is generally available in two forms: surface-mounted and wall-mounted.

[0003] Currently, the illumination direction of recessed downlights on the market is fixed and cannot be adjusted, resulting in a fixed illumination direction and area, which cannot meet more usage needs. Utility Model Content

[0004] The purpose of this invention is to provide a downlight with adjustable illumination direction to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a downlight with adjustable lighting direction, including a heat sink, a front ring, a middle ring, and a lighting component. The middle ring is fixed inside the front ring, and the front ring is screwed and fixed inside the heat sink. One end of the lighting component extends into the front ring and is rotatably connected to the inner wall of the middle ring. The other end of the lighting component extends out of the front ring. The inner wall surface of the middle ring and the outer wall surface of the lighting component are both arc-shaped to fit together so that the lighting component only has the freedom of rotation along the axial direction of the middle ring.

[0006] In a further embodiment of this utility model, the lighting assembly includes a front lamp cover, a rear lamp cover, and a reflector cup. The front lamp cover and the rear lamp cover are fixed together by screw thread. The reflector cup is disposed inside the front lamp cover and the rear lamp cover, and the edge of the reflector cup is pressed and fixed between the front lamp cover and the rear lamp cover.

[0007] In a further embodiment of this invention, the outer wall surface of the rear lamp cover is arc-shaped and is rotatably connected to the inner wall surface of the middle ring.

[0008] In a further embodiment of this invention, the lighting assembly further includes a lamp holder, which is disposed at the center inside the heat sink and corresponds to the reflector cup, and a lamp plate is disposed on the lamp holder.

[0009] In a further embodiment of this utility model, a rear ring is also included. The rear ring is disposed inside the radiator and is fixed to the front ring by screw thread. The end face of the middle ring and the end face of the rear ring are in contact with each other, and the upper end of the rear lamp cover extends into the rear ring and slides in cooperation with the inner wall of the rear ring.

[0010] The beneficial effects of this utility model are:

[0011] This downlight features curved surfaces on both the inner wall of the central ring and the outer wall of the rear lampshade of the lighting component. The rear lampshade is installed onto the central ring, allowing for a rotatable connection between the outer wall of the rear lampshade and the inner wall of the central ring. During use, rotating the front lampshade causes the rear lampshade to roll on the central ring, thereby changing the placement angle of the lighting component. This allows for variations in the angle and area of ​​illumination, further enhancing practical application. Attached Figure Description

[0019] like Figure 1 In this embodiment, a downlight with adjustable illumination direction is provided, including a heat sink 1, a front ring 2, a middle ring 3, and an illumination component 4. The middle ring 3 is fixed inside the front ring 2, and the front ring 2 is screwed and fixed inside the heat sink 1. One end of the illumination component 4 extends into the front ring 2 and is rotatably connected to the inner wall of the middle ring 3. The other end of the illumination component 4 extends out of the front ring 2. The inner wall surface of the middle ring 3 and the outer wall surface of the illumination component 4 are both arc-shaped to fit together so that the illumination component 4 only has the freedom of rotation along the axial direction of the middle ring 3.

[0020] In this embodiment, specifically, as shown in... Figure 2The lighting assembly 4 includes a front lamp cover 40, a rear lamp cover 41, and a reflector cup 42. The front lamp cover 40 and the rear lamp cover 41 are fixed together by screw thread. The reflector cup 42 is disposed inside the front lamp cover 40 and the rear lamp cover 41, and the edge of the reflector cup 42 is pressed and fixed between the front lamp cover 40 and the rear lamp cover 41, thus fixing the reflector cup 42. In addition, the lighting assembly 4 also includes a lamp holder 43, which is disposed in the center of the heat sink 1 and corresponds to the reflector cup 42. A lamp plate is disposed on the lamp holder 43. After the lamp plate emits light, it diffuses the light through the reflector cup 42 to achieve the lighting function.

[0021] In this embodiment, the outer wall surface of the rear lamp cover 41 is arc-shaped and rotatably connected to the inner wall surface of the middle ring 3. It also includes a rear ring 5, which is located inside the radiator 1 and is screwed onto the front ring 2. The end face of the middle ring 3 and the end face of the rear ring 5 are in contact. The upper end of the rear lamp cover 41 extends into the rear ring 5 and slides against the inner wall surface of the rear ring 5. Thus, the front ring 2, middle ring 3, and rear ring 5 are all fixed inside the radiator 1. The rear lamp cover 41 is then installed onto the middle ring 3, allowing the outer wall surface of the rear lamp cover 41 to rotatably connect with the inner wall surface of the middle ring 3. During use, rotating the front lamp cover 40 causes the rear lamp cover 41 to roll on the middle ring 3, thereby changing the placement angle of the lighting component 4. This can change the angle and area of ​​illumination, further improving practical usage requirements.

[0022] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
