Description

Technical Field

[0001] The utility model belongs to the technical field of lighting, and in particular relates to a glare-proof wide-width lamp holder structure. Background Art

[0002] Desk reading lights, essential tools for study and work, have a direct impact on the user's visual health. Existing desk reading lights are generally too bright. Prolonged work or study in such high-intensity lighting can easily lead to visual fatigue. This is especially true for adolescents, whose vision is still developing and who are more susceptible to adverse effects. Long-term accumulation can even lead to vision problems such as myopia. Therefore, improving the lighting quality of desk reading lights and reducing damage to vision has become a pressing issue.

[0003] In order to address this problem, some desk lamp products that attempt to improve the lighting quality have appeared on the market. For example, the Chinese patent document with the announcement number CN105972510A provides a desk lamp with a uniform light source. The desk lamp is cleverly designed and includes a base, a rotatable lamp arm and a lampshade assembly. The lampshade assembly is provided with an LED light source arranged in a ring shape, and the outer contour of the lampshade assembly is rectangular to achieve uniform distribution of light and rationality of the light coverage area. This design improves the uniformity of lighting to a certain extent and reduces the lighting blind spot. However, although the desk lamp with a uniform light source has made some breakthroughs in lighting uniformity, there is still the problem that the user may look directly at the light source. If the user accidentally looks directly at the inside of the lampshade during use, he will still feel strong light stimulation, which will cause discomfort to the human eye and even damage vision. Although the existing desk lamps with a uniform light source have made some progress in lighting uniformity, there is still room for improvement in protecting eyesight and reducing glare.

[0004] Therefore, in order to solve the problems existing in existing desk reading lamps, it is urgently necessary to provide a wide-width lamp holder structure with anti-glare. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes an anti-glare wide lamp head structure, which can effectively reduce glare and avoid the discomfort of users when looking directly at the light source, while ensuring that the brightness of the lighting area is appropriate and evenly distributed.

[0006] The technical solution of the utility model is achieved as follows: a glare-proof wide-width lamp holder structure includes a lamp body arranged in an elongated strip shape, the middle part of the lamp body is universally connected to the lamp pole; the lamp body includes a wide-width lamp housing with a cavity, the bottom of the wide-width lamp housing is provided with an opening, and the cavity and the opening are communicated with each other; a light-blocking frame is provided at the lower part of the wide-width lamp housing, the light-blocking frame includes an annular frame, the side wall of the annular frame is buckled and connected to the wide-width lamp housing; an annular oblique frame is provided at the lower edge of the annular frame, the annular oblique frame is inclined inward and extends upward; the middle ring opening of the annular oblique frame is penetrated in the upper and lower directions, forming a light-emitting channel that is narrow at the top and wide at the bottom;

[0007] A light bar plate is fixed to the inner side of the top of the wide lamp housing, and a light strip is provided on the circumferential edge of the light bar plate. The inner side of the light strip is provided with a light guide plate and a rhombus plate in sequence from top to bottom; wherein, the rhombus plate is pressed against the upper edge of the annular inclined frame; a plurality of lamp beads are provided on the light strip, and the plurality of lamp beads emit light inward, pass through the light guide plate and the rhombus plate in sequence, and are emitted from the light output channel.

[0008] The utility model can effectively prevent the light source from directly hitting the eyes by setting a light-blocking frame, thereby reducing glare. In addition, the lamp beads emit light inward, pass through the light guide plate and the rhombus plate in sequence, and are emitted from the light outlet channel, ensuring that the brightness of the illuminated area is appropriate and evenly distributed, which can significantly reduce the user's visual burden and alleviate visual fatigue under long-term lighting.

[0009] As a further improvement to the above solution, the sidewalls of the annular inclined frame are conical, inclined, or a combination of conical and inclined surfaces; the angle between the generatrix of the conical surface and the horizontal plane, and the angle between the inclined surface and the horizontal plane, are both α, with 30°≤α≤60°. It should be noted that if the inclination angle is too small, the light shielding is not obvious; if the inclination angle is too large, the light output is more limited and uneven. Configuring the light-blocking frame with an appropriate inclination angle is beneficial for providing a better light-blocking effect, effectively blocking light directly directed at the human eye, especially direct light from the lamp beads, thereby significantly reducing glare.

[0010] As a further improvement of the above solution, the light strip board includes a base portion fixedly connected to the wide-width lamp housing, the middle portion of the base portion is recessed to form a strip-shaped groove; the circumferential edge of the base portion extends downward to form a mounting portion, and the light strip is arranged on the inner side of the mounting portion. The groove can be regarded as a variant of a reinforcing rib, and the shape of the groove enhances the structural stability of the light strip board, and improves the bending strength and torsional strength of the light strip board without adding additional materials. In addition, the provision of the mounting portion makes the installation of the light strip simpler and faster. The mounting portion can be regarded as a reserved mounting frame, and the light strip can be placed directly on the inner side of this frame and connected to the mounting portion by appropriate fixing methods (such as screws, clips, etc.).

[0011] As a further improvement of the above solution, the light strips are arranged on opposite sides on the circumferential edge of the light strip plate; or, the light strips are extended along the circumferential edge of the light strip plate.

[0012] As a further improvement to the above solution, a rib is provided at the junction of the annular frame and the annular oblique frame. This rib has a clearance opening near the annular frame. When the light-blocking frame is engaged with the wide-width lamp housing, the lower edge of the mounting portion of the light strip extends into the clearance opening. The rib, positioned at the junction of the annular frame and the annular oblique frame, significantly improves strength and rigidity, ensuring the overall structural stability of the light-blocking frame and resisting deformation or damage. Furthermore, by rationally arranging the clearance opening and rib placement, the light-blocking frame and the light strip are more tightly coupled and coordinated, ensuring the overall structural stability.

[0013] As a further improvement to the above solution, the upper edge of the annular beveled frame is flush with the upper edges of the multiple ribs, and together they form a support surface against which the rhomboid plate rests. This combined support surface of the annular beveled frame and ribs optimizes the internal layout of the lamp body, making it more compact and reliable.

[0014] As a further improvement to the above solution, multiple lamp beads are located near the light guide plate and distributed along the circumferential edge of the light guide plate; the rhombus plate is located below the lamp beads and the light guide plate. The distribution of the lamp beads along the circumferential edge of the light guide plate allows light to be more evenly distributed across the entire surface of the light guide plate as it propagates within the light guide plate, avoiding concentrated light and reducing glare. Furthermore, the rhombus plate located below the lamp beads and the light guide plate acts as a light regulator, emitting light in a softer, more dispersed manner. Even if an observer looks directly at the lamp, they are less likely to experience glare.

[0015] As a further improvement of the above scheme, a plurality of slots are provided along the side wall of the annular frame, a wedge-shaped block is provided on the inner wall of the wide lamp housing, and a guide surface is provided on the lower part of the wedge-shaped block; the annular frame passes through the guide surface from bottom to top, and the slots are connected with the wedge-shaped block by snapping.

[0016] As a further improvement of the above scheme, a plurality of limit blocks are provided along the circumferential inner wall of the wide lamp housing, and the limit blocks are located above each wedge-shaped block; when the annular frame is buckled with the wide lamp housing from bottom to top, the upper edge of the annular frame is against or away from the limit blocks.

[0017] As a further improvement of the above solution, a top cover is further provided on the outer top of the wide-width lamp housing, and the top cover is adapted to the contour shape of the wide-width lamp housing; a plurality of heat dissipation bumps are provided at both ends of the top of the wide-width lamp housing, and there is a gap between each heat dissipation bump; the top cover is provided with corresponding latching protrusions, and when the top cover is installed on the wide-width lamp housing, the latching protrusions are correspondingly snapped into the gaps.

[0018] Beneficial effects of the utility model:

[0019] (1) The setting of the light-blocking frame, especially the annular oblique frame at its lower edge that extends inward and upward, forms a light-shielding structure that can block light directly directed at the human eye, especially direct light from the lamp beads, thereby significantly reducing glare. The design of the light outlet channel of the annular oblique frame, which is narrow at the top and wide at the bottom, makes the light softer and more dispersed when it is emitted, avoiding the glare and discomfort that may be caused when the user looks directly at the light source;

[0020] (2) The light strip on the light bar board is equipped with multiple lamp beads. The light emitted by the lamp beads passes through the light guide plate, which can initially diffuse and homogenize the light. The rhombus plate further refines and evenly distributes the light through its special crystal structure, so that the light can cover a wider area when it is emitted from the light channel, and the brightness distribution is more uniform.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example

[0044] like Figure 1-Figure 7 As shown, a wide-width anti-glare lamp holder structure includes a lamp body 1 arranged in an elongated strip shape, wherein the middle portion of the lamp body 1 is universally connected to a lamp pole 2;

[0045] The lamp body 1 includes a wide lamp housing 11 having a cavity, the bottom of which is provided with an opening, the cavity and the opening being in communication with each other; a light-blocking frame 12 is provided at the lower portion of the wide lamp housing 11, the light-blocking frame 12 including an annular frame 121, the sidewalls of which are snap-fitted to the wide lamp housing 11; an annular oblique frame 122 is provided at the lower edge of the annular frame 121, the annular oblique frame 122 extending inwardly and upwardly; a central ring opening of the annular oblique frame 122 is continuous in the upper and lower directions, forming a light-emitting channel T1 that is narrow at the top and wide at the bottom;

[0046] In this embodiment, the sidewalls of the annular beveled frame 122 are conical, beveled, or a combination of conical and beveled surfaces. The angle between the generatrix of the conical surface and the horizontal plane, and the angle between the beveled surface and the horizontal plane, are both α, with 30°≤α≤60°. In this embodiment, the projection of the annular beveled frame 122 on the horizontal plane is waist-shaped, and its sidewalls are a combination of conical and beveled surfaces, with conical surfaces at both ends and a beveled surface in the middle. Alternatively, the projection of the annular beveled frame 122 on the horizontal plane is rectangular, and its sidewalls are a combination of multiple beveled surfaces.

[0047] In this embodiment, α values ​​of 40°, 45°, and 50° are preferred. It should be noted that if the tilt angle is too small, the light shielding is not obvious; if the tilt angle is too large, the light output is relatively limited and uneven. Configuring the light-blocking frame 12 at an appropriate tilt angle is beneficial for providing a better light-blocking effect, effectively blocking light directly directed toward the human eye, especially direct light from the lamp bead D1, thereby significantly reducing glare.

[0048] A light strip plate 13 is fixed to the inner side of the top of the wide lamp housing 11, and a light strip 14 is provided on the circumferential edge of the light strip plate 13. The inner side of the light strip 14 is provided with a light guide plate 15 and a rhombus plate 16 in sequence from top to bottom; wherein, the rhombus plate 16 is pressed against the upper edge of the annular oblique frame 122.

[0049] In this embodiment, the light strip board 13 includes a base 131 fixedly connected to the wide lamp housing 11, and the middle part of the base 131 is recessed to form a strip-shaped groove 1311; the circumferential edge of the base 131 extends downward to form a mounting portion 132, and the light strip 14 is arranged on the inner side of the mounting portion 132. The groove 1311 can be regarded as a variant of a reinforcing rib. The shape of the groove 1311 enhances the structural stability of the light strip board 13, and improves the bending strength and torsional strength of the light strip board 13 without adding additional materials. In addition, the provision of the mounting portion 132 makes the installation of the light strip 14 simpler and faster. The mounting portion 132 can be regarded as a reserved mounting frame. The light strip 14 can be placed directly on the inner side of this frame and connected to the mounting portion 132 by appropriate fixing methods (such as screws, clips, etc.).

[0050] In this embodiment, the light strip 14 is disposed on opposite sides of the circumferential edge of the light strip 13; or, the light strip 14 extends along the circumferential edge of the light strip 13. The lamp beads D1 on the light strip 14 emit light inward, which can initially avoid direct exposure to the human eye and reduce dizziness.

[0051] In this embodiment, a rib 123 is provided at the connection between the annular frame 121 and the annular oblique frame 122. Specifically, the rib 123 is triangular in shape and is provided with a clearance opening 1231 near the annular frame 121. When the light-blocking frame 12 is engaged with the wide-width lamp housing 11, the lower edge of the mounting portion 132 of the light strip 13 extends into the clearance opening 1231. The rib 123 is provided at the connection between the annular frame 121 and the annular oblique frame 122, which can significantly improve the strength and rigidity, ensuring that the overall structure of the light-blocking frame 12 is stable and reliable and not prone to deformation or damage. In addition, by rationally arranging the positions of the clearance opening 1231 and the rib 123, it is possible to ensure that the light-blocking frame 12 and the light strip 13 are more closely and coordinated, thereby ensuring the stability of their overall structure.

[0052] In this embodiment, the upper edge of the annular beveled frame 122 is flush with the upper edges of the plurality of ribs 123, and together they form a support surface C1, against which the rhombic plate 16 rests. The annular beveled frame 122 and ribs 123 together form support surface C1, optimizing the internal layout of the lamp body 1 and making its structure more compact and reliable.

[0053] In this embodiment, the plurality of lamp beads D1 are positioned near the light guide plate 15 and distributed along the circumferential edge of the light guide plate 15; the rhombus plate 16 is located below the lamp beads D1 and the light guide plate 15. The distribution of the lamp beads D1 along the circumferential edge of the light guide plate 15 allows light to be more evenly distributed across the entire surface of the light guide plate 15 as it propagates within the interior, avoiding concentrated light and reducing glare. Furthermore, the placement of the rhombus plate 16 below the lamp beads D1 and the light guide plate 15 serves to regulate light, resulting in a softer, more dispersed light output. Even when an observer looks directly at the lamp, glare is less likely to be felt.

[0054] In this embodiment, a plurality of slots 1211 are provided along the sidewall of the annular frame 121. A corresponding wedge-shaped block 111 is provided on the inner wall of the wide-width lamp housing 11. A guide surface 112 is provided at the lower portion of the wedge-shaped block 111. The annular frame 121 passes through the guide surface 112 from bottom to top, and the slots 1211 are engaged with the wedge-shaped block 111. By providing the plurality of slots 1211 on the sidewall of the annular frame 121 and cooperating with the wedge-shaped block 111 on the inner wall of the wide-width lamp housing 11, and in particular the guide surface 112 designed at the lower portion of the wedge-shaped block 111, the annular frame 121 can easily slide over the guide surface 112 from bottom to top during installation until the slots 1211 and the wedge-shaped block 111 are securely engaged.

[0055] In this embodiment, a plurality of stoppers 113 are further provided along the circumferential inner wall of the wide lamp housing 11. The stoppers 113 are located above each wedge-shaped block 111. When the annular frame 121 is engaged with the wide lamp housing 11 from bottom to top, the upper edge of the annular frame 121 abuts against or separates from the stoppers 113. This abutment or clearance between the upper edge of the annular frame 121 and the stoppers 113 effectively ensures accurate and consistent installation and avoids assembly errors caused by inaccurate positioning.

[0056] In this embodiment, the top of the wide-width lamp housing 11 is further provided with a top cover 17, which is adapted to the contour of the wide-width lamp housing 11. Multiple heat dissipation bumps 114 are provided at both ends of the top of the wide-width lamp housing 11, with gaps between each pair of heat dissipation bumps 114. The top cover 17 is provided with corresponding latching protrusions 171, which snap into the corresponding gaps when the top cover 17 is mounted on the wide-width lamp housing 11. Preferably, the top cover 17 and the wide-width lamp housing 11 can be made of metal to facilitate light emission and heat dissipation of the lamp body 1.

[0057] Through the above solution of the present invention, in a specific application: the light strip 14 is provided with a plurality of lamp beads D1, and the plurality of lamp beads D1 emit light inward, pass through the light guide plate 15 and the rhombus plate 16 in sequence, and are emitted from the light outlet channel T1. The setting of the light-blocking frame 12, especially the annular inclined frame 122 at its lower edge that extends inward and upward, forms a light-shielding structure that can block light directly directed at the human eye, especially direct light from the lamp bead D1, thereby significantly reducing glare; the design of the light outlet channel T1 of the annular inclined frame 122 that is narrow at the top and wide at the bottom makes the light softer and more dispersed when emitted, avoiding the glare and discomfort that may occur when the user looks directly at the light source; in addition, the light strip 14 on the light bar 13 is provided with a plurality of lamp beads D1, and the light emitted by the lamp bead D1 passes through the light guide plate 15, which can initially diffuse and homogenize the light, and the rhombus plate 16 further refines and evenly distributes the light through its special crystal structure, so that the light can cover a wider area when emitting from the light outlet channel T1, and the brightness distribution is more uniform.

[0058] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation to the present invention.
