Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a small-angle T8 lamp tube. Background Technology

[0002] In the field of lighting technology, small-angle T8 fluorescent tubes have been widely used in specific applications due to their unique lighting effects. Existing small-angle T8 fluorescent tubes offer numerous advantages. First, they provide excellent long-distance lighting. Due to their concentrated light, they can effectively project light onto the ground in high spaces such as industrial plants and warehouses, maintaining high brightness and uniform illuminance. Furthermore, the light decays slowly, meeting the lighting needs of work areas. Second, their small-angle light emission characteristics reduce light scattering into surrounding unrelated areas, minimizing light interference and effectively reducing light pollution. In places with high requirements for lighting environments, such as hospital wards and school classrooms, they can prevent direct light from shining into people's eyes, creating a more comfortable lighting environment.

[0003] However, on the one hand, the light output efficiency of the optical lens of ordinary small-angle lamp tubes needs to be improved, making it difficult to meet the requirements of higher lighting effects, and there is a bottleneck in improving the overall lighting effect. On the other hand, the structural design of the lamp tubes is insufficient in terms of light focusing and preventing light leakage, making it impossible to achieve a more precise small-angle lighting effect. Utility Model Content

[0004] The purpose of this utility model is to provide a small-angle T8 lamp tube, which aims to solve the technical problems in the prior art. On the one hand, the light output efficiency of the optical lens of ordinary small-angle lamp tubes needs to be improved, making it difficult to achieve higher lighting effect requirements and creating a bottleneck in improving the overall lamp effect. On the other hand, the structural design of the lamp tube is insufficient in terms of light focusing and preventing light leakage, making it impossible to achieve a more precise small-angle lighting effect.

[0005] To achieve the above objectives, this utility model employs a small-angle T8 lamp tube, comprising two lamp tube plugs, a power module, a lamp board body, and a lamp tube body. The power module and the lamp board body are connected by a wire. The lamp board body is provided with multiple LED beads. The lamp tube body includes a lamp tube lens and a lower end of the lamp tube, and the lamp tube lens and the lower end of the lamp tube are integrally formed. A lamp board mounting bracket is provided inside the lamp tube, and the lamp board mounting bracket has a mounting area. The two lamp tube plugs are symmetrically arranged at both ends of the lamp tube body. The power module is disposed in one of the lamp tube plugs and extends into the lamp tube body. The lamp board body is disposed on the mounting area.

[0006] The lamp tube lens has a lens layer on its inner side, and the lens layer has a focusing groove, with multiple LED beads arranged towards the focusing groove.

[0007] The installation area has L-shaped blocks at both ends, and the two L-shaped blocks abut against the outer edge of the lamp panel body.

[0008] Each lamp tube plug has multiple mounting grooves on its end face, and each mounting groove is provided with a mounting block. Multiple fixing blocks are glued to both ends of the lamp tube body, and each mounting block and each fixing block are connected by screws.

[0009] The lamp tube body is provided with positioning blocks at both ends. Each positioning block has a polygonal groove. Each lamp tube plug has a polygonal rod on its inner side, and the polygonal rod is inserted into the polygonal groove.

[0010] This utility model discloses a small-angle T8 lamp tube. The lamp tube lens is integrally formed with the lower end of the lamp tube, and a lens layer is provided on the inner side of the lamp tube lens. The lens layer has a focusing groove, and multiple LED beads are arranged in the direction of the focusing groove. This design, through internal optical design, enables the light of the LED beads to converge, achieving a light-focusing effect and improving the light output efficiency of the optical lens. It can break through the bottleneck of improving the overall light effect and achieve higher lighting effect requirements. The mounting area has L-shaped blocks at both ends, and the two L-shaped blocks abut against the outer edge of the lamp board body. The structural design of the lamp tube body, etc., helps to better achieve light convergence and prevent light leakage in the structure, enabling a more precise small-angle lighting effect.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1 to 7 This utility model provides a small-angle T8 lamp tube, including two lamp tube plugs 1, a power module 2, a lamp board body 3, and a lamp tube body 4. The power module 2 and the lamp board body 3 are connected by a wire. The lamp board body 3 is provided with multiple LED beads 6. The lamp tube body 4 includes a lamp tube lens and a lower end of the lamp tube. The lamp tube lens and the lower end of the lamp tube are integrally formed. A lamp board mounting bracket 6 is provided inside the lamp tube. The lamp board mounting bracket 6 has a mounting area 7. The two lamp tube plugs 1 are symmetrically arranged at both ends of the lamp tube body 4. The power module 2 is disposed in one of the lamp tube plugs 1 and extends into the lamp tube body 4. The lamp board body 3 is disposed on the mounting area 7.

[0022] In this embodiment, the small-angle T8 lamp tube of this design has a beam angle of less than 90°, which is more concentrated than the 160°-180° wide-angle beam of ordinary T8 lamp tubes. This characteristic allows the light to be projected more precisely onto specific areas, improving lighting efficiency. It is suitable for places requiring localized focused lighting, such as exhibit displays in museums and shop window lighting. It also offers good long-distance lighting performance: due to the concentrated light, the small-angle T8 lamp tube maintains high brightness and illuminance uniformity during long-distance lighting, with slower light attenuation. For example, in high-ceilinged spaces such as industrial plants and warehouses, the small-angle T8 lamp tube can effectively project light onto the ground, meeting the lighting needs of the work area. Simultaneously, the small-angle beam reduces light scattering into surrounding unrelated areas, minimizing light interference and effectively reducing light pollution. In places with high requirements for lighting environment, such as hospital wards and school classrooms, using small-angle T8 lamp tubes can avoid direct light shining into people's eyes and create a more comfortable lighting environment. Compared with ordinary small-angle lamp tubes on the market, this design uses optical lenses, which have a very high light output efficiency of over 95%, and the overall light efficacy is easier to achieve. This structural design makes the overall structure of the lamp tube compact and reasonable. The one-piece molded lamp tube body 4 enhances the sealing and stability of the lamp tube, reduces the possibility of light leakage from structural gaps, and helps the light to better propagate and converge internally. The lamp board mounting bracket 6 and the mounting area 7 provide a stable mounting position for the lamp board body 3, ensuring the positional accuracy of the LED beads 6, thus laying the foundation for achieving precise small-angle lighting, while also facilitating production assembly and improving production efficiency.

[0023] Furthermore, a lens layer 8 is provided on the inner side of the lamp tube lens, the lens layer 8 has a focusing groove 9, and the plurality of LED beads 6 are arranged in the direction of the focusing groove 9.

[0024] In this embodiment, the focusing groove 9 of the lens layer 8 can effectively converge and guide the light emitted by the LED beads 6, making the light more concentrated and significantly improving the light output efficiency of the optical lens. This breaks through the bottleneck of improving the overall light efficiency of ordinary small-angle lamps, meets higher lighting effect requirements, achieves brighter and more concentrated small-angle lighting, reduces unnecessary light scattering and waste, and through the internal optical design, the light of the LED beads 6 is focused to achieve a focusing effect, thus realizing a small-angle effect.

[0025] Furthermore, L-shaped blocks 10 are provided at both ends of the installation area 7, and the two L-shaped blocks 10 abut against the outer edge of the lamp panel body 3.

[0026] In this embodiment, the L-shaped block 10 plays a good role in fixing and limiting, which can firmly fix the lamp board body 3, prevent the lamp board body 3 from shifting or shaking during use, and ensure the relative position stability between the LED beads 6 and the lamp tube lens.

[0027] Furthermore, each of the lamp tube plugs 1 has multiple mounting grooves 11 on its end face, and each mounting groove 11 is provided with a mounting block 12. Multiple fixing blocks 13 are bonded to both ends of the lamp tube body 4, and each mounting block 12 and each fixing block 13 are connected by screws 14.

[0028] In this embodiment, this connection method makes the connection between the lamp plug 1 and the lamp body 4 more secure and reliable, enhances the overall structural strength of the lamp, and effectively prevents the lamp from loosening or separating due to vibration or external force during use.

[0029] Furthermore, each end of the lamp tube body 4 is provided with a positioning block 15, the positioning block 15 has a polygonal groove 16, and each lamp tube plug 1 has a polygonal rod 17 on its inner side, and the polygonal rod 17 is inserted into the polygonal groove 16.

[0030] In this embodiment, the insertion and engagement of the polygonal rod 17 and the polygonal groove 16 achieves precise positioning, enabling the quick and accurate determination of the installation position between the lamp plug 1 and the lamp body 4.

[0031] In this invention, the lamp board body 3, which is equipped with the plurality of LED beads 6, is accurately installed onto the mounting area 7 of the lamp board mounting bracket 6 provided inside the lamp tube body 4. At this time, the L-shaped blocks 10 at both ends of the mounting area 7 will abut against the outer edge of the lamp board body 3 to secure it firmly and prevent it from shifting. Next, the power module 2 is installed into one of the lamp tube plugs 1 and extends into the lamp tube body 4 to ensure a stable power supply to the LED beads 6. Then, the two lamp tube plugs 1 are symmetrically installed at both ends of the lamp tube body 4, so that the polygonal rod 17 on the inner side of each lamp tube plug 1 is accurately inserted into both ends of the lamp tube body 4. Precise positioning is achieved in the polygonal groove 16 within the positioning block 15. Then, the mounting block 12 at the mounting groove 11 on the end face of the lamp tube plug 1 is firmly connected to the fixing blocks 13 at both ends of the lamp tube body 4 by screws 14, ensuring that the lamp tube plug 1 and the lamp tube body 4 are tightly combined. After installation, the power is turned on, and the light emitted by the LED beads 6 is focused by the focusing groove 9 of the lens layer 8 inside the lamp tube lens. The light is emitted through the integrated structure of the lamp tube lens and the lower end of the lamp tube, achieving concentrated and precise small-angle lighting, which meets the lighting needs of high-ceiling spaces such as industrial plants and warehouses, as well as places with high light environment requirements such as hospital wards and school classrooms.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
