Description

Technical Field

[0001] This utility model relates to a horizontal table lamp, belonging to the technical field of lighting fixtures. Background Technology

[0002] A horizontal desk lamp is a desk lamp whose design features a horizontally oriented body. By positioning the lamp body horizontally, it can cover a larger horizontal lighting area, making it suitable for scenarios that require large-area horizontal lighting, such as long and narrow desks, and conveniently illuminating different areas such as books and computers at the same time.

[0003] The national AA-level illuminance standard for eye-protection desk lamps requires that the illuminance of the lamp be above 250 LX within a 500mm*700mm rectangular area on a specified measurement plane, and above 500 LX within a 300mm*500mm rectangular area in the center. The illuminance uniformity within the central area must be less than or equal to 3, and the overall illuminance uniformity must be less than or equal to 7. Therefore, to achieve this standard, the conventional approach in existing technology is to use an optical three-piece set (reflective paper + light guide plate + diffuser plate).

[0004] For example, the utility model patent with Chinese patent application number CN202120460521.0 discloses an intelligent sensor desk lamp, which achieves uniform light emission by setting up structures such as a diffuser plate, a light guide plate, and a light-emitting sheet, thereby protecting the user's eyesight.

[0005] However, in actual use, it still has the following problems:

[0006] It only uses the conventional optical three-piece set and does not make any special settings for the corresponding light guide plate dot structure. The diameter of the dots on the common light guide plate is about 0.5mm and the spacing is about 0.7mm. This makes it difficult to achieve a high uniformity and high brightness light emission effect even when paired with a diffuser plate. In addition, pairing it with a diffuser plate will increase the cost. Utility Model Content

[0007] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a horizontal table lamp.

[0008] The technical solution of this utility model is as follows:

[0009] A horizontal table lamp includes a base and a lamp head, which are connected by a lamp pole. A light guide plate is disposed inside the lamp head, and light strips are arranged around the periphery of the light guide plate. The light guide plate is divided into a light-emitting section and a light-receiving section. The light-emitting section is located in the center of the light guide plate, and the light-receiving section surrounds the light-emitting section. Both the light-emitting and light-receiving sections contain several rows of dot groups, each dot group containing several dots, each dot having a diameter of 0.18–0.22 mm. The spacing between dots in the same row in the light-emitting section is 0.35–0.45 mm, and the spacing between dots in the same row in the light-receiving section is 0.55–0.65 mm. Reflective paper is also disposed inside the lamp head, parallel to the light guide plate.

[0010] The distance between each side of the light-emitting part and the corresponding side edge of the light guide plate is 'a', and the distance 'a' is set to be less than half the width 'b' of the light guide plate.

[0011] Wherein, the spacing a is one-fifth to one-third of the width b.

[0012] The lamp head includes a first housing and a first cover plate. The first cover plate is fixedly disposed on one side wall of the first housing. A first placement groove is formed inward on the side wall of the first housing close to the first cover plate. Reflective paper, light guide plate and lamp strip are all disposed in the first placement groove. The reflective paper is disposed on the bottom wall of the first placement groove, the light guide plate is disposed on the reflective paper, and the lamp strip is embedded in the peripheral side wall of the first placement groove. A light outlet hole is formed on the first cover plate.

[0013] The first housing has a mounting base on the side wall away from the first cover plate. The lamp post includes a first connecting rod arranged horizontally and a second connecting rod arranged vertically. Both ends of the first connecting rod are rotatably connected to the mounting base and the top of the second connecting rod respectively through a rotating shaft. The bottom end of the second connecting rod is provided with a mounting ear, which is fixedly connected to the base.

[0014] The base includes a second housing and a second cover plate. The second cover plate is fixedly disposed on the top of the second housing, and the mounting ears are fixedly connected to the second cover plate. A second placement groove is provided inward on the top of the second housing, and a counterweight steel plate is disposed in the second placement groove. An anti-slip pad is disposed on the bottom of the second housing.

[0015] The second cover plate also has a decorative sticker on its top surface, which covers the top surface of the second cover plate and the mounting ears.

[0016] This utility model has the following beneficial effects:

[0017] This invention optimizes the dot parameters on the light guide plate by reducing the diameter and spacing of the dots. This allows for a denser and more precise distribution of dots on the light guide plate, resulting in more uniform light scattering during propagation. This reduces uneven brightness caused by excessively large dot diameters and spacing. Furthermore, the smaller diameter dots allow for more precise control of light propagation. Combined with the arrangement of small dot spacing in the light-emitting section and large dot spacing in the light-receiving section, this enhances the light emission effect, providing more pronounced light. Compared to existing technologies, this invention achieves excellent light emission uniformity and brightness without the need for a diffuser plate, offering advantages such as reduced costs and superior visual effects.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Example: Please refer to Figures 1-4 This embodiment provides a horizontal table lamp, including a base 1 and a lamp head 2, which are connected by a lamp pole 3.

[0029] In this embodiment, the lamp head 2 includes a first housing 21 and a first cover plate 22. The first cover plate 22 is fixedly mounted on the right side wall of the first housing 21 by screws. A first placement groove 23 is formed inward on the right side wall of the first housing 21. A reflective paper 9, a light guide plate 4, and a lamp strip 5 are disposed in the first placement groove 23. The reflective paper 9 is a single-sided frosted PET reflective paper, which is fixedly adhered to the bottom wall of the first placement groove 23 and covers the bottom wall of the first placement groove 23. The light guide plate 4 is a PMMA extruded flat plate, which is adhered to the reflective paper 9 and arranged parallel to the reflective paper 9. The projected area of ​​the light guide plate 4 is smaller than that of the reflective paper 9 to ensure that all light reflected by the reflective paper 9 can pass through the light guide plate 4. The lamp strip 5 is embedded in the peripheral side wall of the first placement groove 23 and is arranged around the light guide plate 4. The first cover plate 22 has a light-emitting hole 24 that extends through the first cover plate 22 for the emission of subsequent light.

[0030] In this embodiment, the light guide plate 4 has a rectangular structure and is divided into a light emitting section 6 and a light receiving section 7. The light emitting section 6 is also rectangular and is located in the middle of the light guide plate 4, with its center point coinciding with the center point of the light guide plate 4. The light receiving section 7 has a rectangular frame structure and surrounds the light emitting section 6. The outer edge of the light receiving section 7 is the edge of the light guide plate 4, so that the light generated by the subsequent lamp strip 5 first enters the light receiving section 7 and then enters the light emitting section 6. Both the light emitting section 6 and the light receiving section 7 have several rows of dots 8. The specific number of rows of dots 8 is selected according to the actual size of the light guide plate 4. Each group of dots 8 includes several dots 8, and the specific number of dots 8 is also selected according to the actual size of the light guide plate 4. The diameter of each dot 8 is 0.18 to 0.22 mm, preferably 0.2 mm. The spacing between dots 8 in the same row of the light-emitting section 6 is 0.35-0.45 mm, preferably 0.4 mm. At the same time, the spacing between dots 8 in adjacent rows of the light-emitting section 6 can be 0.35-0.45 mm, preferably 0.4 mm. The spacing between dots 8 in the same row of the light-entry section 7 is 0.55-0.65 mm, preferably 0.6 mm. The spacing between dots 8 in adjacent rows of the light-entry section 7 can be 0.55-0.65 mm, preferably 0.6 mm, so that the overall distribution of dots 8 is regular.

[0031] In this embodiment, through the aforementioned overall setup, when performing lighting work, the light emitted by the light strip 5 enters from the light-incident part 7 on the light guide plate 4. Part of the light is emitted directly from the light-emitting part 6 on the light guide plate 4 towards the light-emitting hole 24, while the other part of the light is emitted towards the reflective paper 9 and reflected back onto the light guide plate 4 by the reflective paper 9, so that it can be emitted from the light-emitting part 6 on the light guide plate 4 towards the light-emitting hole 24 to achieve the required lighting work. Compared to the traditional horizontal table lamp structure, this embodiment optimizes the parameters of the dots 8 on the light guide plate 4 by reducing the diameter and spacing of the dots 8. This allows the dots 8 to be distributed more densely and finely on the light guide plate 4, resulting in more uniform light scattering during propagation. This reduces uneven brightness caused by excessively large dot diameters and spacing. Furthermore, the smaller diameter dots 8 allow for more precise control of light propagation. This, combined with the arrangement of small dot spacing in the light-emitting section 6 and large dot spacing in the light-incident section 7 (if all dots 8 on the light guide plate 4 were evenly distributed, the light-incident section 7 might experience localized overbrightness due to excessive light concentration), further enhances the effect. The light-emitting section 6 will be dark due to insufficient light. Therefore, the large spacing of the dots 8 in the light-incident section 7 can reduce unnecessary light scattering, allowing more light to propagate along the light guide plate 4 to the light-emitting section 6. This reduces light loss in the early stage of propagation and avoids local overbrightness in the light-incident section 7, ensuring uniform light emission. The small spacing of the dots 8 in the light-emitting section 6 increases the chance of light scattering, thereby compensating for light attenuation and effectively scattering light onto the light-emitting surface of the light guide plate 4. This improves light utilization and light emission brightness, thus enhancing the light emission effect and providing more obvious light. Compared with existing technologies, it has excellent light emission uniformity and light emission brightness without the need for a diffuser plate.

[0032] In this embodiment, adjacent groups of dots 8 in the light-emitting section 6 and adjacent groups of dots 8 in the light-receiving section 7 can be arranged in an alternating manner on the light guide plate 4, which can reduce the texture of the dots 8 and thus ensure the uniformity of subsequent light emission.

[0033] In this embodiment, the distance between each side of the light-emitting part 6 and the corresponding side edge of the light guide plate 4 is 'a'. The distance 'a' is set to be less than half the width 'b' of the light guide plate 4, preferably one-fifth to one-third of the width 'b'. By rationally dividing the area ratio of the light-emitting part 6 and the light-incident part 7 as described above, the overall brightness of this horizontal table lamp can be improved, making the overall picture more harmonious.

[0034] In this embodiment, a mounting base 25 is fixedly installed on the side wall of the first housing 21 away from the first cover plate 22 by means of screw connection. The lamp post 3 includes a first connecting rod 31 arranged horizontally and a second connecting rod 32 arranged vertically. Both ends of the first connecting rod 31 are rotatably connected to the mounting base 25 and the top end of the second connecting rod 32 respectively by means of a rotating shaft 33, so that the required angle can be adjusted. The bottom end of the second connecting rod 32 is fixedly provided with a mounting ear 34, which is fixedly connected to the base 1.

[0035] In this embodiment, the base 1 includes a second housing 11 and a second cover plate 12. The second cover plate 12 is fixedly disposed on the top of the second housing 11, and the mounting ear 34 is fixedly connected to the second cover plate 12 by screws. A second placement groove 13 is formed inward from the top of the second housing 11, and a counterweight steel plate 14 is disposed in the second placement groove 13. The second cover plate 12, the counterweight steel plate 14, and the second housing 11 are fixedly connected together by screws. An anti-slip pad 15 is fixedly adhered to the bottom of the second housing 11. By setting the counterweight steel plate 14 and the anti-slip pad 15, the counterweight steel plate 14 can optimize the overall gravity distribution of the horizontal table lamp, and the anti-slip pad 15 can prevent the horizontal table lamp from sliding. The combination of the two can greatly reduce the probability of the horizontal table lamp tipping over, thereby effectively preventing the table lamp from being damaged.

[0036] In this embodiment, a decorative sticker 16 is also affixed to the top surface of the second cover plate 12. The decorative sticker 16 is arranged to cover the top surface of the second cover plate 12 and the mounting ears 34. By covering the top surface of the second cover plate 12 and the mounting ears 34, the decorative sticker 16 can hide the mounting holes and mounting ears 34 on the second cover plate 12, thereby improving the overall aesthetics of the horizontal table lamp.

[0037] In this embodiment, the housing and cover of the lamp head 2 and the base 1 can be made of high-temperature resistant PC+silicone composite material that is already available in the prior art, so that its temperature resistance can be increased to 120°C, thereby improving the service life of this horizontal table lamp.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
