Description

Technical Field

[0001] The present invention relates to a beam adjustment device for a furniture linear lamp, belonging to the technical field of furniture lighting. Background Art

[0002] With the continuous development of modern furniture, consumers' pursuit of furniture products is increasingly inclined to be intelligent, multifunctional and aesthetic. Among them, lamps are not only the key independent objects in the research of furniture intelligence and aesthetics, but also an important component in forming a unique and beautiful home. Based on this, although the use of lamps in modern homes still retains the original lighting function, their optical functions are increasingly being used to present more unique visual effects. In this case, different shapes of lamps and light sources are being more and more commonly used in the field of modern homes. Among them, linear light sources and linear lamps are one of them.

[0003] In some relatively fixed scenarios, the manifestation form of the light source in the home will remain relatively fixed for a long time. Therefore, it is relatively costly to use electrical control methods such as circuit control. In this case, it is more necessary and cost-saving to manually adjust the irradiation angle, irradiation surface, etc. of the lamp through a mechanical structure. However, due to the increasingly powerful functions and complex structures of modern homes, the traditional method of simply fixing the light source and adjusting the light-shielding components of the light source is becoming less and less applicable. Therefore, how to set more applicable linear lighting products on various forms of home products is an important technical problem in this field. At the same time, in the process of solving the problem, it is often necessary to fix the light source on a rotating component. For a light source that requires an external power supply, the connection line may become loose during multiple rotations, causing a short circuit and even a fire. Summary of the Invention

[0004] Aiming at the technical problems of small applicability and easy loosening of the light source connection line during multiple rotations in the beam adjustment of linear light sources in modern home products, which increases the risk of open circuit, short circuit or even fire, the present invention provides a beam adjustment device for a furniture linear lamp, and the technical solutions adopted are as follows:

[0006] Preferably, the clamping member 1 is provided with a clamping cavity 11 fixed to the furniture, and an arc-shaped mounting cavity 12 for mounting the carrier 4 and the beam adjusting member 2; one end of the arc-shaped outer side surface of the carrier 4 is detachably fixed to one end of the inner side surface of the mounting cavity 12 to form a closed end of the mounting cavity 12; the arc-shaped rotating portion 22 of the beam adjusting member 2 is movably inserted into the arc-shaped gap formed between the outer side surface of the carrier 4 and the inner side surface of the mounting cavity of the clamping member 1.

[0009] More preferably, an adjusting portion 21 is provided at the outer end of the arc-shaped rotating portion 22; the adjusting portion 21 extends out of the arc-shaped opening of the mounting cavity 12 as a handle for adjusting the beam angle.

[0010] Preferably, the beam adjusting device further includes a lamp shade 3 made of a light-transmitting material, and the lamp shade 3 is detachably fixed to the upper part of the light source mounting cavity 43 of the carrier 4.

[0011] Preferably, the carrier 4 is provided with an arc-shaped outer side surface, and a convex rib structure with an increasing width is provided at one end of the arc-shaped outer side surface; a light source mounting cavity 43 is provided inside the carrier 4, and the two sides of the light source mounting cavity 43 are arc-shaped side walls; lamp shade fixing ribs 421 are provided on the inner sides of the ends of the arc-shaped side walls.

[0012] More preferably, a flat light source fixing surface 411 is provided on the light source mounting cavity 43 along the length direction.

[0013] More preferably, a plugging groove 121 matching the convex rib structure is provided on the inner wall of one arc-shaped side wall of the mounting cavity 12 of the clamping member 1.

[0014] More preferably, the beam adjusting device further includes a lamp shade 3 made of a light-transmitting material; the lamp shade 3 includes an arc-shaped light filtering surface that is convex outward, and concave clamping teeth are provided on both sides of the arc-shaped light filtering surface along the length direction, and fixing ribs 321 are provided on the outer sides of the ends of the clamping teeth; the lamp shade fixing ribs 421 are clamped and held on the concave surface of the clamping teeth, and the position of the lamp shade fixing ribs 421 is limited and blocked by the fixing ribs 321.

[0015] Beneficial effects obtained by the present invention compared with the prior art:

[0016] Through the plug-in fixation of the clamping member and the bearing member, the present invention realizes the detachable fixation of the furniture connection component and the lamp connection component, thus greatly increasing the applicability of the beam adjustment device under different furniture conditions. At the same time, the beam adjustment member is movably inserted into the cavities of the bearing member and the clamping member, and the beam angle of the linear lamp is changed by rotating the beam adjustment member, so that the linear lamp projects light with different widths or amplitudes, presenting different visual effects for the furniture.

[0017] The linear lamp is fixed on the light source fixing surface of the bearing member. The light source is fixed to the furniture through the bearing member and the clamping member. The beam angle projected by the light source is changed by the beam adjustment member rotating in the arc-shaped gap between the clamping member and the bearing member. This design method avoids the problem that the lamp and its connecting wires rotate during the adjustment of the light beam bundle, and can effectively avoid problems such as circuit breakage and short circuit during the rotation process. At the same time, this adjustment method does not require the aid of a complex control device and can be adjusted manually, with the characteristics of low cost, good practicability and wide application range.

[0032] The present invention will be further described in detail below with reference to specific drawings, but the present invention is not limited by the following detailed description.

[0033] Figure 1 It is a schematic structural diagram of the cross-section of the clamping member in a preferred embodiment of the present invention. From Figure 1It can be seen that in this preferred embodiment, the clamping member is mainly composed of an integrally formed structural member that forms a clamping cavity 11 capable of clamping the edge of a rectangular strip and an installation cavity 12 capable of installing a cylindrical component. Among them, a part of the main body forming the installation cavity 12 is an arc-shaped structure, a plane is formed on the outer side of the middle of the arc, a plane extends from one end of the arc, and finally a clamping portion 111 extends parallel to the plane on the same side at the end of this plane, thereby forming a cavity capable of clamping a rectangular strip structure. The installation cavity 12 is provided with an opening, and a dovetail groove-shaped insertion slot 121 with a rounded corner at the turning point is provided on one side of the two free ends opposite to the opening for connecting the carrier 4.

[0034] Figure 2 This is a schematic cross-sectional structure diagram of the beam adjuster in a preferred embodiment of the present invention. From Figure 2 It can be seen that in this preferred embodiment, the cross-section of the beam adjuster 2 is sickle-shaped, which has an arc-shaped adjusting portion 21 and a rotating portion 22 that acts as a handle. The shape of the beam adjuster 2 matches the shapes of the clamping member 1 and the carrier 4, and can be inserted into the arc-shaped gap formed between the clamping member 1 and the carrier 4 and rotated, so as to change the beam angle of the light emitted by the light source installed on the carrier 4. As can be seen from the figure, the inner side of the adjusting portion 21 of the beam adjuster 2 is an arc-shaped rotating surface 222, and convex rib structures, that is, convex ribs 221, are provided along the length direction on a part of the outer circumference.

[0035] Figure 3 This is a schematic cross-sectional structure diagram of the lamp shade in a preferred embodiment of the present invention. From Figure 3 It can be seen that in this preferred embodiment, the lamp shade structure is similar to a π-shaped structure. Its top is an outwardly convex arc-shaped structure, and both sides are inwardly concave at the connecting sides and outwardly convex at the free ends. Since elastic deformation often needs to occur in the clamping tooth structures on both sides during installation, concave grooves 311 are provided on both sides of the arc-shaped top surface to facilitate deformation. And fixed ribs 321 are formed outward at the ends of the clamping teeth on both sides, and the fixed ribs 321 and the inwardly concave structure at the connecting end form an "S" shape structure to facilitate connection with the carrier 4.

[0036] Figure 4 This is a schematic cross-sectional structure diagram of the carrier in a preferred embodiment of the present invention. From Figure 4It can be seen that in the preferred embodiment, the cross section of the carrier 4 is an arc-shaped structure with a notch. The arc-shaped outer side surface matches the inner side surface of the clamp 1, and at one end thereof, a plug-in edge 42 is provided to complement the plug-in groove 121 of the clamp 1. A light source installation cavity 43 for installing a linear light source is provided inside the cross section of the carrier 4, and a straight light source fixing surface 411 is provided in the length direction of the light source installation cavity 43. The two ends of the light source fixing surface 411 are arc-shaped side surfaces, and a lampshade fixing edge 421 is provided at the end of the arc-shaped side surface to facilitate the fixed connection with the aforementioned "S"-shaped structure.

[0037] Figure 5 It is a schematic diagram of the cross-sectional structure of a light beam adjustment device assembly in a preferred embodiment of the present invention. Figure 6 for Figure 5 Schematic diagram of the three-dimensional structure. Figure 5 and Figure 6 It can be seen that the preferred beam adjustment decoration is respectively composed of Figures 1 - 4 The components shown are fixedly connected by plugging or snapping. Among them, the plug-in edge 42 of the carrier 4 is plugged into the dovetail-shaped plug-in groove 121 of the clamp 1. At the same time, since the circumferential diameter of the outer wall of the carrier 4 is smaller than the circumferential diameter of the inner wall of the clamp 1, an arc-shaped gap is formed between the two. The plug-in groove 121 forms a closed end on one side of the arc-shaped gap, and the other side of the arc-shaped gap is connected to the notch of the clamp 1. The light beam adjustment member 2 is just plugged into the arc-shaped gap and is fixedly connected by static friction when stationary. When adjustment is needed, the user can rotate the light beam adjustment member 2 by pulling the rotating part 22 to block the beam angle of the light emitted by the light cover 3.

[0038] In the above embodiments, the linear light source of the beam adjustment device can be a strip light strip, and the lampshade can be made of existing materials with certain elasticity and light transmittance such as plastic. The beam adjustment device can be installed in the horizontal position of furniture such as bookcases and wardrobes, so that the furniture has a three-dimensional visual effect.

[0039] Figure 7 FIG. 1 is a schematic structural diagram of a cross section of a clamping member in a second preferred embodiment of the present invention. Figure 7 It can be seen that in this preferred embodiment, the clamping member and Figure 1 The difference between the clamping parts shown is that the clamping cavity 11 is arranged at the side of the installation cavity 12, rather than at the rear. A cavity 14 is arranged in the installation cavity 12 to reduce the weight of the component. At the same time, a fixing column 13 is also arranged in the clamping cavity 11, so that a stable connection can be achieved by inserting the fixing column 13 into the part of the home that needs to be fixed.

[0040] Figure 8 It is a schematic structural diagram of the cross section of a carrier in a second preferred embodiment of the present invention.Figure 9 is Figure 8 a schematic diagram of the three-dimensional structure. From Figure 8 and Figure 9 it can be seen that the structure of the clamping member 1 selected for the beam adjusting device in this specific implementation is Figure 7 the clamping member shown. The connection manner of each internal component is the same as that of the structure shown in Figure 6 This implementation is mainly applicable to installing current lamps on furniture such as wardrobes and bookcases in the vertical direction, or even on the wall surface, to produce a vertical visual effect.

[0041] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various modifications and decorations without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the claims.
