Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lamp body and a lamp. Background Technology

[0002] To improve the appearance quality of lamps, as well as their corrosion resistance and wear resistance, the lamp body needs to be electroplated to form a coating on the surface of the lamp body.

[0003] In related technologies, the lamp body is manufactured using a single die-casting process. However, the die-casting process easily creates sand holes and bubbles on the surface of the die-cast parts, resulting in relatively poor surface uniformity (e.g., sand holes, bubbles, hard particles). Since the uniformity of the lamp body's surface structure affects the adhesion of the plating layer, it consequently impacts the appearance quality of the lamp body after electroplating. Therefore, in related technologies, poor surface uniformity of the lamp body leads to relatively poor uniformity of the plating layer, resulting in poor appearance quality of the lamp body. Consequently, when the lamp body is assembled into a luminaire, the luminaire's appearance quality is also poor. Utility Model Content

[0004] This utility model discloses a lamp body and a lamp fixture to solve the problem of poor appearance quality of lamp fixtures in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] In a first aspect, this application discloses a lamp body, which includes an annular main body and a mounting base. The annular main body is a cylindrical extruded metal part, and the mounting base is a die-cast metal part. The mounting base is disposed within the annular main body and includes a base body and an auxiliary mounting part. The base body is a disc-shaped structure, and the auxiliary mounting part is disposed within the base body. The outer peripheral edge of the base body is fitted and welded to the inner wall of the annular main body.

[0007] Secondly, this application also discloses a lamp, which includes a light source assembly, a light-transmitting assembly, and the lamp body described in the first aspect. The light source assembly and the light-transmitting assembly are both mounted on the base body through the auxiliary mounting part, and the light-transmitting assembly is located on the light-emitting side of the light source assembly.

[0008] The technical solution adopted in this utility model can achieve the following technical effects:

[0009] This embodiment of the application configures the lamp body with a structure including an extruded annular main body and a die-cast mounting base, resulting in a relatively uniform surface structure of the annular main body. Consequently, during electroplating of the lamp body, the plating layer formed on the surface of the annular main body is also relatively uniform, thus improving the appearance quality of the annular main body. When the lamp body is assembled into a luminaire, the outer surface of the annular main body serves as the appearance surface of the luminaire, thereby enhancing the overall appearance quality of the luminaire.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] Please refer to Figures 1 to 4 This utility model discloses a lamp body 100, which includes an annular main body portion 110 and a mounting base portion 120. When the lamp body 100 is applied to a lamp fixture, the outer surface of the annular main body portion 110 can serve as the appearance surface of the lamp fixture.

[0022] The annular main body 110 is a cylindrical extruded metal part, while the mounting base 120 is a die-cast metal part. The annular main body 110 has a relatively simple and regular structure, therefore, it can be formed by extrusion molding. The mounting base 120, however, serves as the mounting foundation for at least some other components of the luminaire (such as the light source assembly 200, the light-transmitting assembly 300, etc.). The mounting base 120 has a relatively complex structure (for example, it requires auxiliary mounting parts 122 for mounting components such as the light source assembly 200 and the light-transmitting assembly 300), therefore, it needs to be formed by die casting.

[0023] It should be noted that both extrusion molding and die casting are existing technologies. Products formed by extrusion molding have characteristics such as dense grain structure and smooth surface. Therefore, the surface structure of products formed by extrusion molding is relatively uniform.

[0024] The mounting base 120 is disposed within the annular main body 110. The mounting base 120 includes a base body 121 and an auxiliary mounting part 122. The auxiliary mounting part 122 may be an internally threaded post 122a, an externally threaded post, a clearance hole 122b, etc. The base body 121 is a disc-shaped structural component, and the auxiliary mounting part 122 is disposed within the base body 121. The outer peripheral edge of the base body 121 is fitted against the inner wall of the annular main body 110 and is welded together.

[0025] Of course, the outer peripheral edge of the base body 121 can also be press-fitted with the inner wall of the annular body 110 so that the base body 121 is snapped into the annular body 110 without welding. Of course, the base body 121 can also be connected to the annular body 110 by means of bolts, clips, or other connections. This application embodiment does not impose specific limitations on the connection method between the base body 121 and the annular body 110.

[0026] This embodiment of the application configures the lamp body 100 with a structure including an extruded annular main body portion 110 and a die-cast mounting base portion 120. This results in a relatively uniform surface structure of the annular main body portion 110, leading to a relatively uniform plating layer formed on the surface of the annular main body portion 110 during electroplating, and consequently, a smoother surface. Because the surface of the annular main body portion 110 is relatively smooth, its appearance quality is relatively good. When the lamp body 100 is assembled into a lamp fixture, the outer surface of the annular main body portion 110 serves as the appearance surface of the lamp fixture, thus improving the overall appearance quality of the lamp fixture.

[0027] Since the mounting base 120 is located inside the annular main body 110, and the mounting base 120 does not serve as the exterior surface of the lamp, the electroplating effect of the mounting base 120 will not affect the appearance quality of the lamp.

[0028] Since the outer periphery of the base body 121 is attached to and welded to the inner wall of the annular body 110, the base body 121 and the annular body 110 have a good thermal conductivity, which is beneficial to the heat dissipation of the lamp when the lamp body 100 is installed in the lamp.

[0029] The cross-sectional shape of the annular main body 110 perpendicular to its central axis can be circular, elliptical, polygonal, etc. The embodiments of this application do not impose specific restrictions on the cross-sectional shape of the annular main body 110 perpendicular to its central axis.

[0030] Optionally, both the annular main body 110 and the mounting base 120 can be made of aluminum alloy. Since aluminum alloy has a relatively low density and is lightweight, it is beneficial to the lightweight design of the lamp body 100 when both the annular main body 110 and the mounting base 120 are made of aluminum alloy.

[0031] Of course, the annular main body 110 and the mounting base 120 can also be other metal parts, such as copper alloy parts, steel alloy parts, titanium alloy parts, etc. The embodiments of this application do not impose specific restrictions on the structure of the annular main body 110 and the mounting base 120.

[0032] When assembling the mounting base 120 and the annular body 110, to facilitate the confirmation of their relative positions, the inner wall of the annular body 110 may optionally be provided with a limiting protrusion 111. The limiting protrusion 111 can be used to limit and engage with the edge of the base body 121 during the installation of the mounting base 120 within the annular body 110. When assembling the mounting base 120 and the annular body 110, if the base body 121 moves to a position where its edge (e.g., the end face of the base body 121) engages with the limiting protrusion 111, it can be confirmed that the mounting base 120 and the annular body 110 are properly installed, thus simplifying the confirmation of their relative positions.

[0033] Optionally, the limiting protrusion 111 can be an annular structural member extending along the inner wall of the annular body portion 110, so that the limiting protrusion 111 can be limited and engaged with the edge of the base body 121 in the circumferential direction, thereby making the relative position between the base body 121 and the annular body portion 110 more accurate when the base 120 and the annular body portion 110 are assembled (for example, avoiding tilting between the base body 121 and the annular body portion 110).

[0034] To make the lighting fixtures more intelligent, they can be equipped with sensors that detect hand gestures, allowing users to control the lights by turning them on or off, or selecting different lighting modes. Optionally, a mounting groove 112 can be provided on the inner wall of the annular main body 110 for mounting the hand gesture sensor. It should be noted that the mounting groove 112 is formed after the annular main body 110 is extruded.

[0035] This application also discloses a lamp, which includes a light source assembly 200, a light-transmitting assembly 300, and a lamp body 100 as disclosed in the above embodiments. Both the light source assembly 200 and the light-transmitting assembly 300 are mounted on the base body 121 via an auxiliary mounting part 122, and the light-transmitting assembly 300 is located on the light-emitting side of the light source assembly 200.

[0036] The lamp disclosed in this application, by setting the lamp body 100 as described in the above embodiments, makes the surface structure of the annular main body 110 relatively uniform. Therefore, when the lamp body 100 is electroplated, the plating layer formed on the surface of the annular main body 110 is also relatively uniform, resulting in a relatively good appearance quality for the annular main body 110. When the lamp body 100 is assembled into the lamp, since the outer surface of the annular main body 110 serves as the appearance surface of the lamp, the appearance quality of the lamp can be improved.

[0037] Optionally, the light-transmitting component 300 may include a first bracket 310 and a light-transmitting element 320. The first bracket 310 can be mounted on the base body 121 via an auxiliary mounting part 122. For example, the first bracket 310 may have a first clearance hole, and the lamp may also include a first screw. The auxiliary mounting part 122 may be an internally threaded post, and the first screw may pass through the first clearance hole and engage with the internally threaded post, thereby enabling the first bracket 310 to be mounted on the base body 121. Of course, the auxiliary mounting part 122 may also be a snap-fit ​​or other structure. This application embodiment does not specifically limit the structure of the auxiliary mounting part 122. The light-transmitting element 320 may be disposed on the first bracket 310, and the first bracket 310 may have a clearance hole 311.

[0038] The light source assembly 200 may include a second bracket 210 and a light-emitting element 220. The second bracket 210 can be mounted on the base body 121 via an auxiliary mounting part 122. For example, the second bracket 210 may have a second clearance hole, and the lamp may also include a second screw. The auxiliary mounting part 122 may be an internally threaded post, and the second screw may pass through the second clearance hole and engage with the internally threaded post, thereby enabling the second bracket 210 to be mounted on the base body 121. Of course, the auxiliary mounting part 122 may also be a snap-fit ​​or other structure. This application embodiment does not specifically limit the structure of the auxiliary mounting part 122. The light-emitting element 220 may be disposed on the second bracket 210 and may be opposite to the clearance hole 311.

[0039] The lamp disclosed in this application has a clearance hole 311 on the first bracket 310, so that the light-emitting element 220 is opposite to the clearance hole 311. This allows the light emitted by the light-emitting element 220 to enter the space enclosed by the first bracket 310 and the light-transmitting element 320 through the clearance hole 311 and then exit from the light-transmitting element 320. The inner wall of the clearance hole 311 can block the light projected onto it by the light-emitting element 220, thereby helping to alleviate the problem of light leakage in the lamp.

[0040] Optionally, the light source assembly 200 may further include a control board 230, which may be disposed on the second bracket 210, and the light-emitting element 220 may be disposed on the control board 230. The control board 230 may be used to control the light emission brightness, color, etc. of the light-emitting element 220.

[0041] To mitigate the risk of the light-transmitting element 320 being easily crushed during installation, the light-transmitting assembly 300 may optionally include an annular buffer pad 330 and a connector 340. The annular buffer pad 330 can be clamped between the edge of the light-transmitting element 320 and the first bracket 310, and the light-transmitting element 320 can be installed on the first bracket 310 via the connector 340.

[0042] The lamp disclosed in this application embodiment has an annular buffer pad 330, which can be clamped between the edge of the light-transmitting element 320 and the first bracket 310. The buffering effect of the annular buffer pad 330 can alleviate the situation where the light-transmitting element 320 is easily crushed during installation.

[0043] Specifically, the annular buffer pad 330 can be a component with a certain degree of elasticity, such as a rubber pad or foam. This application embodiment does not impose specific limitations on the type of annular buffer pad 330. The connector 340 can be a structure such as a buckle, tape, or clip. This application embodiment does not impose specific limitations on the type of connector 340.

[0044] To further improve the appearance quality of the luminaire, the luminaire may optionally include a decorative ring 700, which may be disposed on the first bracket 310 and may surround the light-transmitting element 320.

[0045] Optionally, the luminaire may also include a lamp body cover 400, a base 500, and a rotating arm 600. The light-transmitting component 300 may be disposed at the first port of the annular main body 110. The lamp body cover 400 may be connected to the base body 121 and may be disposed at the second port of the annular main body 110. The rotating arm 600 may be rotatably disposed on the base 500, and the lamp body cover 400 may be connected to the rotating arm 600.

[0046] The lamp disclosed in this application embodiment has a base 500 and a rotating arm 600. When the rotating arm 600 rotates, it can drive the light source assembly 200 to rotate. This allows the lamp to adjust its lighting position according to actual needs, which is beneficial for the lamp to achieve more usage scenarios.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment.
