Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture for preventing and relieving eye strain. Background Technology

[0002] To address the eye health problems faced by modern people, especially eye strain and dry eye caused by prolonged exposure to poor lighting conditions, a special light therapy called golden light has been developed. Golden light has a color temperature of 1800-2000K and is composed of silicon-based yellow and red LEDs. The yellow LEDs have a wavelength of 560-570nm, and the red LEDs have a wavelength of 615-625nm. This light source does not contain blue-violet light components below 500nm, thus effectively relieving eye strain.

[0003] Currently, people add LED beads that emit a golden light to lamps to prevent and relieve eye strain. However, to flexibly adapt to various lighting needs, flexible tubular structures such as serpentine tubes and corrugated tubes are often used as lamp arms. This leads to dust accumulation on the lamp arms, especially in the folds or joints of the serpentine tubes. Furthermore, due to the structural features of these folds and joints, users find it difficult to clean the dust, resulting in a decrease in the aesthetics and visual appeal of the lamps. Utility Model Content

[0004] The main purpose of this invention is to provide a lamp for preventing and relieving eye strain, aiming to solve the problem of users having difficulty cleaning the lamp arm in related technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A lamp for preventing and relieving eye strain includes a lamp holder, a lamp arm, and a lamp cover. A first rotating mechanism is provided between the lamp arm and the lamp cover. The first rotating mechanism includes a first locking ring and a first rotating ring. The first locking ring is fixedly connected to the lamp arm, and the first rotating ring is rotatably connected to the first locking ring. The lamp cover is fixedly connected to the first rotating ring. A self-locking structure is provided between the first locking ring and the first rotating ring.

[0007] Furthermore, the self-locking structure includes a locking component and several locking slots for cooperating with the locking component. Each of the locking slots is opened on the first locking ring disk and is evenly distributed around the first locking ring disk. The locking component is linked with the first rotating ring disk.

[0008] Furthermore, the locking member is slidably connected to the first rotating ring disk, and an elastic member is provided between the locking member and the first rotating ring disk. Each locking groove includes a linkage surface for enabling the locking member and the first rotating ring disk to move together.

[0009] Furthermore, the locking component has a spherical structure.

[0010] Furthermore, each of the aforementioned locking components and elastic components is provided in multiples, and each of the aforementioned locking components and elastic components is evenly distributed around the first rotating ring disk.

[0011] Furthermore, the lampshade includes a connecting block and a cover body. The first rotating mechanism is located between the connecting block and the lamp arm. A second rotating mechanism is provided between the connecting block and the cover body. The second rotating mechanism has the same structure as the first rotating mechanism, and their rotation axes are perpendicular to each other.

[0012] Furthermore, the connecting block is provided with a first mating groove and a second mating groove for cooperating with the first rotating mechanism and the second rotating mechanism.

[0013] Furthermore, a transfer plate is provided between the locking member and the elastic member, and the transfer plate is provided with an abutment groove for cooperating with the locking member.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. The present invention adopts a traditional fixed lamp arm and adds a first rotating mechanism at the connection between the lamp pen and the lamp cover to avoid the presence of concave structures such as wrinkles and joint gaps on the lamp arm. This fundamentally solves the problem that dust easily accumulates in these structures, thus making the present invention easy to clean.

[0016] Meanwhile, due to the presence of the first rotating mechanism, the lampshade can still rotate around the lamp arm or the first rotating mechanism as the center, thereby adjusting the lampshade and changing the position of the light components (such as golden light beads) located in the lampshade, realizing the adjustment of the light position, and ensuring that the golden light emitted by this utility model provides good lighting relief for users, so as to prevent and relieve eye fatigue.

[0017] The first rotating mechanism mainly includes a first positioning ring disk and a first rotating ring disk. The first positioning ring disk is fixedly connected to the lamp arm, and the first rotating ring disk is rotatably connected to the first positioning ring disk, with a self-locking structure between them. The lamp cover is fixedly connected to the first rotating ring disk. Thus, by pushing the lamp cover to rotate the first rotating ring disk, the self-locking structure between the first rotating ring disk and the first positioning ring disk will fix the first rotating ring disk, making it difficult for it to continue rotating without external force intervention, thus ensuring the structural stability of the adjusted structure of this utility model.

[0018] 2. Furthermore, since the first rotating mechanism is mainly formed by the cooperation of two ring structures, it naturally has a through hole for the line to pass through, which effectively avoids the presence of the first rotating mechanism affecting the wiring (such as wires) between the lamp arm and the lamp cover.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Example 1

[0032] like Figures 1-3 As shown, this embodiment proposes a lamp for preventing and relieving eye strain, mainly including a lamp holder 1, a lamp arm 2, and a lamp shade 3. The lamp arm 2 is fixedly mounted on the lamp holder 1 and serves to support the lamp shade 3. A light assembly is installed inside the lamp shade 3, so that this embodiment can provide light illumination at a suitable position. The light assembly mainly includes several LED beads that can emit golden light, so that this embodiment can prevent and relieve the user's eye strain by providing golden light to the user.

[0033] Meanwhile, a first rotating mechanism 4 is provided between the lamp arm 2 and the lamp cover 3. That is, the lamp cover 3 changes its position by rotating through the first rotating mechanism 4, rather than by swinging or bending the shape of the lamp arm 2. In this way, the lamp arm 2 can still adopt the traditional fixed lamp arm design, thereby avoiding the presence of wrinkles, joint gaps and other concave structures on the surface of the lamp arm 2 in this embodiment. This solves the problem of dust accumulating in these structures from the root, and greatly facilitates the cleaning work of this embodiment.

[0034] Specifically, the first rotating mechanism 4 mainly includes a first positioning ring disk 41 and a first rotating ring disk 42. The first positioning ring disk 41 is fixedly connected to the lamp arm 2, and the first rotating ring disk 42 is rotatably connected to the first positioning ring disk 41. The cooperation of the two ring structures makes the inner ring naturally have a wire hole for wires and other lines to pass through, thereby effectively avoiding the need for the wires and other lines in this embodiment to avoid obstacles due to the existence of the first rotating mechanism 4. Moreover, since each line is located in the inner ring of the first rotating ring disk 42, the rotational movement of the first rotating mechanism 4 will not interfere with each line, ensuring the safety of the lines and the stability of the operation of this embodiment.

[0035] Preferably, the first locking ring 41 and the first rotating ring 42 are respectively provided with a plurality of first connecting countersunk holes and a plurality of second connecting countersunk holes. Each first connecting countersunk hole and each second connecting countersunk hole is provided with a first connector and a second connector. Each first connector and the second connector are respectively threaded to connect the lamp arm 2 and the lamp cover 3, thereby realizing the installation of the first rotating mechanism 4 between the lamp arm 2 and the lamp cover 3.

[0036] The lampshade 3 is fixedly connected to the first rotating ring disk 42. A self-locking structure 43 is provided between the first locking ring disk 41 and the first rotating ring disk 42. That is, by manually pushing or pulling the lampshade 3, the lampshade 3 rotates around the first rotating ring disk 42 as the center, thereby realizing the position adjustment of the lampshade 3. Moreover, due to the existence of the self-locking structure 43 between the first locking ring disk 41 and the first rotating ring disk 42, its self-locking function can fix the first locking ring disk 41 in the rotated position. Without manual intervention, it is difficult to rotate it again, thereby effectively ensuring the positional stability after adjustment in this embodiment, so as to ensure that this embodiment can stably provide light and lighting environment.

[0037] like Figures 3-5 As shown, the self-locking structure 43 in this embodiment mainly includes a locking member 431 and several locking slots 432 for cooperating with the locking member 431. The locking member 431 is located on the first rotating ring disk 42. Each locking slot 432 is opened on the first locking ring disk 41 and is evenly distributed around the first locking ring disk 41 in a circular pattern. This ensures that when the first rotating ring disk 42 rotates at multiple angles, there is a corresponding locking slot 432 that can cooperate with the locking member 431 located on its surface to achieve self-locking, thus ensuring the practicality of the self-locking structure 43 and that the self-locking structure 43 has a sufficient range of applications.

[0038] Meanwhile, the locking component 431 is linked with the first rotating ring disk 42. That is, when the first rotating ring disk 42 rotates (external force intervenes), the self-locking structure 43 can automatically cancel and stop the self-locking function, thereby facilitating the adjustment work of this embodiment.

[0039] Specifically, the locking component 431 is slidably connected to the first rotating ring disk 42, and an elastic element 433 is provided between the locking component 431 and the first rotating ring disk 42. Each locking slot 432 includes a linkage surface for interlocking the locking component 431 and the first rotating ring disk 42. That is, when the first rotating ring disk 42 rotates, it drives the locking component 431 to move. During the excessive movement, the locking component 431 contacts the linkage surface and is displaced on the first rotating ring disk 42 under the structural guidance of the linkage surface, thereby compressing the elastic element 433. When the locking component 431 moves to the next locking slot 432 (and stops rotating the first rotating ring disk 42), the locking component 431 will pop out again under the action of the elastic element 433 and abut against the locking slot 432, thereby increasing the friction between the first rotating ring disk 42 and the first locking ring disk 41, achieving self-locking. This automatic self-locking requires no electricity or manual intervention, is energy-saving, and highly reliable.

[0040] Among them, the positioning component 431 has a spherical structure, which ensures that when the positioning component 431 contacts the first positioning ring disk 41 (regardless of whether it contacts a plane, inclined plane or curved surface), it can automatically adjust the contact point to avoid local stress concentration and reduce wear; and the spherical structure of the positioning component 431 has less resistance when rolling on the linkage surface, making the operation of the first rotating ring disk 42 smoother (if necessary, it can be used with lubrication or low friction coating).

[0041] Preferably, in this embodiment, the locking grooves 432 (linkage surfaces) are all curved or arc-shaped structures, so that the locking grooves 432 can better cooperate with the locking components 431.

[0042] Meanwhile, there are several locking components 431 and elastic components 433. Each locking component 431 and each elastic component 433 is evenly distributed around the first rotating ring disk 42, so that there are multiple friction points between the first rotating ring disk 42 and the first locking ring disk 41, which further improves the self-locking effect of the self-locking structure 43.

[0043] A transfer plate 434 is provided between the locking component 431 and the elastic component 433. The transfer plate 434 is fixedly connected to the elastic component 433, meaning that the transfer plate 434 replaces the elastic component in contacting the locking component 431. The transfer plate 434 makes surface contact with the elastic component 433, effectively transferring the force from the displacement of the locking component 431 to the elastic component 433. This prevents the locking component 431 from rotating during contact with the elastic component 433, thus ensuring proper force transmission (e.g., single-point pressure). Simultaneously, the transfer plate 434 has an abutment groove 4341 for engaging with the locking component 431. The abutment groove 4341 is also arc-shaped to ensure good contact between the transfer plate 434 and the locking component 431.

[0044] Example 2

[0045] Based on Example 1, such as Figures 6-7 As shown, the lampshade 3 in this embodiment includes a connecting block 31 and a cover body 32. The first rotating mechanism 4 is located between the connecting block 31 and the lamp arm 2. A second rotating mechanism 5 is provided between the connecting block 31 and the cover body 32. That is, the first rotating mechanism 4 can drive the lampshade 3 as a whole to be adjusted, while the second rotating mechanism 5 drives the cover body 32 to be partially adjusted. The second rotating mechanism 5 has the same structure as the first rotating mechanism 4, and their rotation axes are perpendicular to each other. That is, the lampshade 3 in this embodiment can achieve multi-angle adjustment through the cooperation of the first rotating mechanism 4 and the second rotating mechanism 5, making the use of this embodiment more flexible and practical.

[0046] The connecting block 31 is provided with a first mating groove 311 and a second mating groove 312 for cooperating with the first rotating mechanism 4 and the second rotating mechanism 5, so that the first rotating mechanism 4 and the second rotating mechanism 5 can be hidden inside the connecting block 31, and the connecting block 31 itself can also play a role in protecting the first rotating mechanism 4 and the second rotating mechanism 5, making the operation of this embodiment more stable.
