Description

Technical Field

[0001] The present application relates to the technical field of lighting lamps, and in particular to a lamp. Background Art

[0002] Table lamps are a commonly used lighting tool in households. In order to ensure a sufficient lighting range, the support rod of a table lamp in the prior art usually has a long length or a large volume so that the lamp head can illuminate at the best angle. Therefore, the support rod accounts for a large proportion of the overall volume of the table lamp. In order to make full use of the support rod, some table lamps on the market use light-guiding materials to make the support rod, and groove or punch holes in the support rod so that the light emitted by the light source is scattered from the groove or hole of the support rod, so that the support rod plays a part of the role of the light source. However, the light scattered from the groove or hole has problems such as uneven brightness distribution and insufficient softness of the light, and the production cost is high. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a lamp, comprising a base, a lamp head and a light guide. The light guide is supported between the base and the lamp head, and the light guide has two light guide end faces that are far away from each other, one of the light guide end faces is connected to the base, and the other light guide end face is connected to the lamp head. The interior of the light guide is provided with at least one light guide channel connecting the two light guide end faces, the light guide is made of light guiding material, and the light guide channel is made of light diffusion material. At least one of the base and the lamp head has a light-emitting component, and the light-emitting component faces the light-guiding end face. When the light-emitting component is powered on and emits light, the light will propagate along the light guide and the light guide channel. The light guide channel can scatter the light while propagating the light, thereby realizing the function of emitting light. Since the light diffusion material has a uniform density, there will be no discontinuous change in light intensity when scattering the light, so the scattered light is softer.

[0004] In some embodiments, the light guide is hollow and tubular, preferably circular, with the plurality of light guide channels evenly distributed along the circumference of the light guide between the inner and outer walls. Circular tubes offer isotropic strength and stiffness in the radial direction and are a common shape for support structures.

[0005] In some embodiments, the light guide extends straight from the base to the lamp head. In bedside lamps and floor lamps, the support member adopts a straight line design, which is not only beautiful but also saves space.

[0006] In some embodiments, the light guide may also be plate-shaped, and the light guide channels are arranged along the width direction of the light guide.

[0007] In some embodiments, the light-emitting assembly includes a first light strip having a plurality of first lamp beads distributed along the circumference of the light guide, with each first lamp bead aligned with a corresponding light guide channel. When powered, the lamp beads illuminate the light guide and the light guide channels, allowing the light guide channels to function as light sources.

[0008] Furthermore, the light emitting assembly further comprises a second light strip arranged around the periphery of the first light strip, the second light strip having a plurality of second lamp beads, and the second light strip serving as a supplementary light source can further enhance the lighting capability of the lamp.

[0009] The light guide is detachably connected to the base and the lamp holder, which is convenient for installation and maintenance.

[0010] In some embodiments, a connecting screw is provided in the middle of the light guide, one end of the connecting screw being connected to the base and the other end being connected to the lamp holder. During daily use, the connecting screw and the light guide form a stable support structure, and the connecting screw is easy to disassemble, facilitating installation and maintenance.

[0011] The beneficial effects of this application are as follows: Because a light-guiding channel made of light-scattering material is provided in the light guide, when the light-emitting component is powered on and emits light, the light propagates along the light guide and the light-guiding channel. The light-guiding channel not only propagates the light but also scatters the light, thereby realizing the function of a light source. This not only fully utilizes the supporting structure of the lamp, improving the lighting effect of the lamp, but also provides uniform and soft light, and reduces production costs.

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other alternative implementations obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] Figure 1 and Figure 2 The first embodiment of the present application is shown, which provides a lamp including a base 1, a lamp holder 2, and a light guide 3. The light guide 3 is supported between the base 1 and the lamp holder 2. The light guide 3 has two light guide end faces 31 spaced apart from each other, one of which is fixedly connected to the base 1, and the other is fixedly connected to the lamp holder 2. The light guide 3 is internally provided with a plurality of light guide channels 32 connecting the two light guide end faces 31. The light guide 3 is made of a light-guiding material, and the light guide channels 32 are made of a light-diffusing material.

[0020] The lamp head 2 is equipped with a light-emitting assembly 21, which faces a light-guiding end face 31. When the light-emitting assembly 21 is powered on and emits light, the light propagates along the light guide 3 and the light-guiding channel 32. The light-guiding channel 32 not only propagates the light but also scatters it, thus fulfilling the function of a light source. Because the light-diffusing material has a uniform density, the scattered light does not exhibit discontinuous changes in light intensity, resulting in a softer scattered light.

[0021] Commonly used light-guiding materials include polymethacrylate (also known as acrylic), polystyrene, and polycarbonate. Light-diffusing materials scatter light by adding a light-diffusing agent to the light-guiding material. Common light-diffusing agents include barium sulfate, calcium carbonate, or silicon dioxide. These materials are all known in the art and will not be described in detail here.

[0022] In the first embodiment, as Figure 2 As shown, the light guide 3 is a circular tube. A circular tube has isotropic strength and stiffness in the radial direction and is a common shape for support structures. The light guide 3 can also take other shapes, such as a circular tube, rectangular tube, triangular tube, solid rectangular column, plate, etc., as long as it can provide support.

[0023] In the first embodiment, the light guide 3 and light guide channel 32 extend linearly from the base 1 to the lamp head 2. In table lamps and floor lamps, a linear support structure is not only aesthetically pleasing but also space-saving. In practical applications, the light guide 3 can also extend in other ways, such as a broken line or curved line, to suit different lighting needs.

[0024] In the first embodiment, as Figure 2 As shown, the light guide channels 32 are evenly distributed between the inner wall and the outer wall of the light guide 3 along the circumference of the light guide 3. When the light emitting assembly 21 is powered, the light guide channels 32 emit light, and the light can be emitted from the entire circumference of the light guide 3. The distribution of the light guide channels 32 in the light guide column 3 can also be changed according to the shape of the light guide column 3, such as Figure 3 As shown, when the light guide column 3 is plate-shaped, the light guide channels are arranged along the width direction of the light guide body.

[0025] In the first embodiment, the light guide channel 32 extends in a straight line in the light guide column 3, as shown in FIG. Figure 1 As shown, the shape is simple and the production cost is low. The light guide channel 32 can also be spirally extended or in other specific shapes as needed.

[0026] In the first embodiment, the light guide 3 and light guide channel 32 are manufactured using a dual-plastic extrusion process, a mature technology with good molding effects and low cost. The light guide 3 and light guide channel 32 can also be provided separately. For example, if the light guide column 3 is a solid cylinder, a separate light guide channel 32 is provided at the center of the light guide column 3 to achieve the same luminous effect.

[0027] In the first embodiment, as Figure 1 As shown, the light-emitting assembly 21 includes a first light strip having a plurality of first lamp beads 211. The plurality of first lamp beads 211 are distributed along the circumference of the light guide 3, and each first lamp bead 211 is aligned with a corresponding light guide channel 32. Furthermore, the light-emitting assembly 21 can be installed on the base 1 as needed, so that the lamp head 2 and the light guide channels 32 near the base 1 have the same brightness. Alternatively, the light-emitting assembly 21 can be installed only in the base 1 as needed to meet the lighting needs of different areas.

[0028] Figure 4 The second embodiment of the present application is shown, in which the light-emitting component 21 also includes a second light strip arranged around the periphery of the first light strip, and the second light strip has a plurality of second lamp beads 212. The second lamp beads 212 serve as a supplementary light source and can further improve the lighting capacity of the lamp. One end of the light guide 3 is plugged into the base 1, and the other end is plugged into the lamp head 2, and a connecting screw 4 is provided in the middle of the light guide 3, one end of the connecting screw 4 is movably connected to the base 1, and the other end is movably connected to the lamp head 2. During daily use, the connecting screw 4 cooperates with the light guide 3 to form a stable support structure, and the connecting screw 4 is easy to disassemble, which facilitates installation and maintenance.

[0029] In the second embodiment, the light emitting assembly 21 can be powered not only by a power cord, but also by a Figure 4As shown, the lamp is powered by a battery 5 arranged in the lamp holder 2, the battery 5 is electrically connected to the light-emitting component 21, and a foam 6 is arranged between the battery 5 and the light-emitting component 21, which can reduce the vibration suffered by the battery 5 and isolate the heat generated by the light-emitting component 21, thereby effectively protecting the battery.

[0030] As a further improvement of the second embodiment, Figure 4 and Figure 5 As shown, the lamp bead 211 can also be covered with a lampshade 22, and the lampshade 22 is made of light-guiding material or light-scattering material, and the light generated by the lamp bead 211 can penetrate the lampshade 22. A touch switch 23 can also be provided in the lamp head 2 to control the working state of the lamp bead 211. The touch switch 23 is electrically connected to the light-emitting component 21. Compared with the traditional push-button switch, the touch switch 23 is not only beautiful, but also easy to use, has good sealing, is strong and durable, and is very reliable. At the same time, a push-button switch 24 can also be provided on the light-emitting component 21, and a through hole 221 is provided on the lampshade 22 at a position corresponding to the push-button switch 24, and the push-button switch 24 extends from the through hole 221. Both the push-button switch 24 and the touch switch 23 can control the working state of the light-emitting component 21, which is more convenient to use. A button cap 25 can also be provided on the button 24 to play a role in dustproof, waterproof and aesthetic.

[0031] Furthermore, a counterweight 11 may be provided in the base 1 to improve the stability of the lamp.

[0032] The shape of the lamp holder 2 in this application is not limited to Figure 5 The conical shape shown can also be any other shape.

[0033] The shape of the base 1 in this application is not limited to Figure 5 The disc shape shown can also adopt any other shape.

[0034] The present invention can be applied not only to lamps with similar structures to the embodiments of the present invention, such as table lamps and floor lamps, but also to lamps with different structures, such as portable lamps and lamp tubes. For example, in a portable lamp, the handle and the lamp base are connected by a light guide, and the light-emitting component is disposed in the handle or the lamp base. The light guide and the light-guiding channel emit light under the illumination of the light-emitting component, thereby realizing the function of a light source.

[0035] Finally, it should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
