This fails to meet users' diverse lighting needs, such as creating an atmosphere or achieving specific functional lighting. Secondly, in terms of optical design, traditional soft-light designs often employ a flat structure, resulting in poor light uniformity and softness, dark areas around edges, and limited glare suppression. Furthermore, the conventional arrangement of the lamp beads makes it difficult to implement innovative features such as zoned light control. These issues impact the user experience and require urgent improvement. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0023] like Figures 1 to 6 As shown, this embodiment proposes a multi-mode adjustable LED eye-protection desk lamp, including a supporting lamp holder 1, a supporting lamp pole 2, and a light-emitting lamp head 3. The supporting lamp holder 1, the supporting lamp pole 2, and the light-emitting lamp head 3 are connected in sequence. The supporting lamp holder 1 is provided with a power interface 13, and the lamp head is provided with a light-homogenizing plate 31. Several groups of light sources are provided inside the light-emitting lamp head 3, and the light sources are fixed to the side walls of the light-emitting lamp head 3. The light sources include a large lamp bead 32 and a group of small lamp groups 33. The large lamp bead 32 and the small lamp group 33 are arranged linearly along the side walls of the light-emitting lamp head 3. Soft light panels 34 are provided on the outside of the large lamp bead 32 and the small lamp group 33. The soft light panels 34 are used to disperse the light source to make the divergent light softer.
[0024] The support lamp holder 1 serves as the foundation of the desk lamp, bearing the weight of the entire lamp and providing stable support. A power interface 13 is provided for connecting to an external power source to power the desk lamp. The support lamp holder 1 ensures that the desk lamp is placed stably and prevents it from tipping over. The power interface 13 facilitates connection of the desk lamp to an external power source, ensuring its normal operation. The support lamp pole 2 connects the support lamp holder 1 and the light-emitting lamp head 3, supporting and fixing the light-emitting lamp head 3. It can also adjust the height and angle of the light-emitting lamp head 3 to a certain extent. The support lamp pole 2 enables the light-emitting lamp head 3 to be positioned in a suitable lighting position, meeting the different needs of users and improving the flexibility of the desk lamp. The light-emitting lamp head 3 is the light-emitting component of the desk lamp, with a light source installed inside. It is a key part in realizing the lighting function. The light homogenizing plate 31 is used to further homogenize the light emitted by the light source to make the light distribution more uniform. The light source serves as the light-emitting unit of the desk lamp. The large lamp beads 32 and the small lamp group 33 emit light to realize the lighting function, and can achieve multi-mode adjustment through different combinations and controls. Modes include Day Mode (color temperature 4000K), Night Mode (color temperature 3000K), and Zero Blue Mode (color temperature 1800K). The light source is fixed to the side wall of the lamp head 3, changing the traditional layout where the lamp beads face directly in the direction of illumination to a side-emitting mode. This approach reduces the probability of light directly hitting the eye, reduces glare, and improves eye comfort. The large lamp beads 32 and small lamp groups 33 are arranged linearly along the side wall, ensuring an orderly distribution of light along the side wall and facilitating overall control and adjustment of the light. This helps optimize the light emission angle and distribution range, further improving light uniformity and controllability. The large lamp beads 32 emit a golden light that resembles natural warm light (such as light at dusk), is soft and non-glaring, and can reduce retinal irritation. This golden light can reduce eye strain during long periods of reading or working, making it particularly suitable for nighttime use or relaxation (such as reading before bed). Compared to cool white light (high color temperature), golden light has a weaker inhibitory effect on melatonin secretion, helping maintain the body's circadian rhythm and reducing fatigue from staying up late. Golden light also has a high color rendering index (Ra ≥ 90), accurately presenting the true color of objects. The diffuser 34 is used to disperse the light emitted by the light source, making it softer. The diffuser 34 effectively reduces the intensity gradient of the light, reducing glare and making the light softer and more comfortable, protecting the user's eyes and enhancing the visual experience.
[0025] The combination of the large lamp beads 32 and the small lamp group 33 can create a variety of practical lighting modes. For example, when the large lamp beads 32, which emit golden light, are turned on alone, they provide a warm, natural-light-like basic illumination, ideal for nighttime relaxation or reading, reducing blue light stimulation and fully utilizing the eye-protective properties of golden light. When the small lamp group 33 is turned on alone, it provides focused localized illumination. Its uniform rectangular arrangement of light can accurately cover detailed areas of the desktop, suitable for delicate operations or temporary fill light to avoid direct glare. When the large lamp beads 32 and the small lamp group 33 are turned on simultaneously, the overall brightness is increased and the lighting range is expanded to meet the needs of work or study scenarios. The golden light is mixed with the white or neutral light of the small lamp group 33 to balance visual comfort and clarity. By controlling the brightness or color temperature of the small light cluster 33 and pairing it with the large golden light beads 32, different lighting effects can be created, such as warm yellow + warm white for a warmer feel, or warm yellow + neutral light for enhanced focus and improved adaptability to various spatial scenarios. Combining large and small light beads, such as gradually brightening / dimming and adjusting color temperature to simulate natural light, can alleviate eye fatigue and be suitable for long periods of focused work. This combination design not only achieves excellent eye protection through golden light, but also meets the user's personalized needs in different scenarios through multi-mode adjustment, significantly improving the product's practicality and user experience.
[0026] In this embodiment, the small lamp group 33 includes a plurality of small lamp beads 331 arranged in a rectangular shape. The soft light plate 34 is an arc-shaped structure, and the two ends of the soft light plate 34 are respectively fixed to the two sides of the large lamp beads 32 or the small lamp group 33.
[0027] The small light group 33 emits light through a combination of multiple small lamp beads 331, supplementing the light output of the large lamp beads 32 to form a denser light source matrix. The rectangular arrangement makes the light distribution of the small light group 33 regular, which facilitates the synergy with the light of the large lamp beads 32. The regularity of the rectangular arrangement helps to evenly diffuse the light in the horizontal and vertical directions, further improving the light uniformity of the illuminated area and reducing dark areas at the edges. The curved structure of the soft light plate 34 can refract and scatter the light emitted by the large lamp beads 32 and the small light group 33 at multiple angles, changing the propagation path of the light; the two ends are fixed on both sides of the light source to ensure that the soft light plate 34 covers the entire light-emitting area and softens all light. Through the optical design of the curved surface, direct light is converted into diffuse light, significantly reducing the directionality and intensity concentration of the light, thereby reducing glare; at the same time, the curved soft light plate 34 can evenly distribute the light over a larger range, further improving the softness and uniformity of the light, optimizing the visual experience and enhancing the eye protection effect.
[0028] In this embodiment, two counterweights 11 are disposed within the support base 1. The counterweights 11 are fixedly connected to the support base 1 and are located on either side of the connection between the support base 1 and the support pole 2. A wiring trough 12 is provided between the two counterweights 11 to facilitate wiring within the base. One end of the wiring trough 12 is connected to a power port 13.
[0029] The counterweight 11 is used to increase the weight of the bottom of the lamp holder 1, adjust the center of gravity of the desk lamp as a whole, and balance the weight distribution of the lamp pole 2 and the light-emitting lamp head 3. The setting of the counterweight 11 can improve the stability of the desk lamp when it is placed, and prevent the desk lamp from tipping over due to the shift of the center of gravity of the lamp head or the lamp pole. In particular, it can remain stable when adjusting the angle of the lamp head, thereby enhancing the safety of use. The wiring trough 12 is used to provide a dedicated channel for the wires from the power interface 13 to the internal circuit of the desk lamp, and standardize the wiring path. The setting of the wiring trough 12 can prevent the wires from being tangled in the base, reduce the risk of damage caused by line friction or extrusion, and facilitate wiring operations during assembly, thereby improving production efficiency. The design of connecting the power interface 13 ensures a smooth current transmission path, and guarantees the stability and reliability of the electrical system of the desk lamp.
[0030] In this embodiment, a bottom cover 4 is provided to support the lamp holder 1. The bottom cover 4 is fixed to the supporting lamp holder 1 by screws. A reinforcement ring 41 and several reinforcement ribs 42 are provided inside the bottom cover 4. The reinforcement ring 41 is located in the middle of the bottom cover 4. One end of the reinforcement rib 42 is fixed to the reinforcement ring 41, and the other end of the reinforcement rib 42 extends toward the edge of the bottom cover 4.
[0031] The bottom cover 4 serves as the enclosed structure supporting the lamp holder 1, enclosing internal components (such as the counterweight 11 and wiring duct 12), forming a complete base housing. Screws secure the bottom cover 4, ensuring a secure installation and facilitating disassembly and maintenance. A reinforcement ring 41 serves as the central support structure for the bottom cover 4, enhancing its center's resistance to deformation and distributing pressure from above (e.g., supporting the lamp post 2 and counterweight 11). This prevents the center of the bottom cover 4 from denting or cracking due to long-term load bearing or external forces, thereby extending the base's service life. The reinforcement ring 41 provides a connection point for the reinforcement ribs 42, forming a radial support framework and enhancing the overall structural strength of the bottom cover 4. The reinforcement ribs 42 radiate from the central reinforcement ring 41 toward the edges of the bottom cover 4, forming a "hub-like" support structure that evenly distributes central pressure to the edges of the bottom cover 4. The reinforcing ribs 42 significantly improve the bending and impact resistance of the bottom cover 4, especially when subjected to side impact or uneven pressure, reducing the risk of edge deformation; the distribution of the reinforcing ribs 42 increases the structural rigidity of the bottom cover 4, reduces the vibration transmission of the base (such as shaking when adjusting the lamp pole), and further improves the stability of the desk lamp during use.
