Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a downlight without dark areas and light leakage. Background Art

[0002] Lamps are lighting tools that need to be installed in every household. There are many types of lamps, and different types are used in different scenarios.

[0003] Downlights are one type of lamps, which are widely used in every household due to their simple shape and small space occupation. In existing downlights, studs are integrally molded on the face ring and then passed through the lampshade. The studs are then matched with the holes on the chassis and screwed in. The problem with this structure is that there is a dark area and light leakage in the gap between the lampshade and the face ring, which greatly affects the usability and aesthetics. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a downlight without dark areas and light leakage, comprising a lampshade, a face ring and a chassis;

[0005] The lampshade has a first end and a second end which are separated from each other;

[0006] A plurality of connection parts are arranged on the second end of the lampshade along its circumference, and the face ring is integrally configured with the lampshade from the first end;

[0007] Wherein, the face ring and the lampshade are connected by ultrasonic welding;

[0008] The chassis is provided with a positioning part corresponding to the connecting part, and the lampshade and the chassis are connected and fixedly connected by inserting and positioning the connecting part and the positioning part.

[0009] A further embodiment of the present invention is that the face ring is fitted onto the edge of the first end of the lampshade.

[0010] A further implementation scheme of the utility model is that the connecting portion and the lampshade are connected by ultrasonic welding.

[0011] A further embodiment of the present invention is that the connecting portion is a stud.

[0012] A further implementation scheme of the utility model is that the positioning portion is a positioning hole, and the positioning hole and the stud are matched. When the lampshade is plugged into the connecting portion and the positioning portion on the chassis, the second end of the lampshade fits the chassis.

[0013] A further embodiment of the present invention is that the chassis is in the shape of a disk or a box.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This downlight abandons the traditional structural design and designs the connection part on the lampshade. The connection part and the lampshade are welded by ultrasonic wave. The face ring is also welded by ultrasonic wave after being attached to the lampshade, so that the joint is tight and will not cause dark areas and light leakage. The lampshade and the chassis are then plugged in and matched through the connection part and the positioning part and finally screwed to complete the assembly, which greatly improves the usability and aesthetics.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Traditional downlights are designed in a form where the studs are injected into the face ring, the face ring is glued to the lampshade, and the studs pass through the lampshade. The problem is that there will be dark areas and light leakage between the face ring and the lampshade, which causes a bad user experience and also has a significant impact on the aesthetics.

[0026] like Figure 1 An embodiment of the utility model provides a downlight without dark areas and light leakage, including a lampshade 1, a face ring 2 and a chassis 3.

[0027] like Figure 2 The lampshade 1 has a first end A and a second end B which are opposite to each other. In this embodiment, the first end A is defined as a lower end, and the second end B is an upward end.

[0028] The first biggest difference is that a plurality of connecting parts 10 are arranged along the circumference of the second end B of the lampshade 1. The connecting parts 10 are studs, and the connecting parts 10 and the lampshade 1 are fixed by ultrasonic welding. The integrated structure after ultrasonic welding is not only aesthetically pleasing, but also firmly connected.

[0029] Secondly, the face ring 2 is integrally configured with the lampshade 1 from the first end A, and the face ring 2 is attached to the edge of the first end A of the lampshade 1. Similarly, the face ring 2 and the lampshade 1 are ultrasonically welded together. It can be understood that in this way, there will be no dark area or light leakage at the joint of the face ring 2 and the lampshade 1, thereby improving the user experience and aesthetics.

[0030] Correspondingly, such as Figure 3 A positioning portion 30 corresponding to the connecting portion 10 is provided on the chassis 3, and the positioning portion 30 is a positioning hole. The lampshade 1 and the chassis 3 are plugged, positioned, matched and locked and fixedly connected through the connecting portion 10 and the positioning portion 30. The positioning hole and the stud are adapted to each other. When the lampshade 1 and the connecting portion 10 and the positioning portion 30 on the chassis 3 are plugged, the second end B on the lampshade 1 fits with the chassis 3.

[0031] Preferably, the chassis 3 has a hook-shaped or box-shaped structure, such as Figure 1 , the disc-shaped base is used as a surface installation, such as Figure 4 The box shape is a concealed installation form, and this embodiment is used for display. Of course, it is preferred but not limited to these two types.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
