Description

Technical Field

[0001] This utility model relates to the field of lighting structures, and in particular to a lamp tube lighting structure with lateral angle light emission and no dark area. Background Technology

[0002] Currently, indoor recessed lighting widely adopts traditional tube structures. Its core design involves a driver (mounting base), light source module (such as LED strip), and lampshade arranged in a straight line in series, and then fixedly embedded in the lamp trough. This layout is technically mature and relatively simple in structure, making it a common solution for basic lighting.

[0003] However, this linear arrangement has revealed significant drawbacks in practical applications. First, uneven light distribution and the tendency to create dark areas are common. This is because all components are arranged in a straight line, with the light source biased to one side of the lamp body. Light from the other side (usually against a wall or in the mounting position) is blocked and cannot effectively diffuse, resulting in noticeably dark areas, uneven overall illuminance, and poor visual effects. Second, installation and placement stability are insufficient. The mounting bases for these lamps are typically designed to be narrow for portability, but this also leads to instability. Whether temporarily placed during installation or upright for later maintenance, the lamps are highly susceptible to tilting or even tipping over due to slight touches or uneven surfaces, increasing operational difficulty and the risk of damage. Furthermore, control and adjustment are extremely inconvenient. The driver power supply and control switches / buttons for dimming and color temperature adjustment are usually concentrated on the back of the base at one end of the lamp body. When adjustments are needed, users cannot see the operating positions directly and must reach into the recessed area or the back of the lamp body to painstakingly search for the control buttons, resulting in low operational efficiency and a poor user experience. These issues directly affect lighting performance, ease of installation, and user experience, and urgently need to be addressed.

[0004] In view of this, this technical solution proposes a side-angle light-emitting tube lighting structure with no dark area. The side-angle light-emitting structure minimizes light loss after installation, and the adjustment switch is located on the side for easy adjustment. The integrated tube profile has a large bottom area, making it less prone to flipping or tilting. The overall structure is sturdy and easy to manufacture and use. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a dark-zone-free lamp tube lighting structure with lateral angle light emission, aiming to solve the problems of poor lighting effect, ease of installation, and poor user experience of existing indoor recessed lamp tubes.

[0006] To achieve the above objectives, this utility model provides a lamp tube lighting structure with lateral angle light emission and no dark area, including a lamp tube body composed of a profile and a lampshade.

[0007] The bottom of the profile is provided with a base that extends protruding into the profile itself, and a mounting groove is provided obliquely on one side of the top of the profile. A light source board is provided inside the mounting groove, and the lampshade encapsulates the light source board in the mounting groove. A dimming component is provided at the bottom of the profile near the mounting groove.

[0008] As a further embodiment of this utility model, limiting clips are formed on the two opposite sides of the top of the mounting groove. The upper part of the limiting clips forms a first limiting part for engaging the two sides of the lampshade, and the lower part of the limiting clips forms a second limiting part for limiting the light source board.

[0009] As a further improvement of this utility model, the lampshade is provided with locking heads on both sides for engaging with the first limiting part.

[0010] As a further embodiment of this utility model, the profile is provided with end caps at both ends, and the light source plate and the lampshade are slidably assembled onto the profile on one side by opening the end caps.

[0011] As a further embodiment of this utility model, the lampshade is provided with a light-uniforming surface inside to prevent light swirl, and the light-uniforming surface is composed of raised tooth-like patterns.

[0012] As a further embodiment of this invention, the angle between the mounting groove and the base is 45°.

[0013] The beneficial effects of this utility model are as follows:

[0014] This technical solution significantly increases the support area through a wide base extending from the bottom of the profile, improving stability during installation and effectively preventing tipping accidents. The 45° angled mounting slot encapsulates the light source board, allowing light to be projected directly outwards at a lateral angle, completely covering traditionally dark areas without relying on wall reflections, achieving true dark-zone-free lighting and improving light uniformity. Simultaneously, the dimming component is located on the outer bottom of the mounting slot, allowing users to adjust parameters directly, eliminating blind operation. In terms of structural assembly, the double-layer design of the limiting clips (the upper first limiting part engages with the lampshade clip, and the lower second limiting part fixes the light source board) ensures precise component positioning. The toothed light-diffusing surface inside the lampshade effectively eliminates glare, improving visual comfort. The end cap and sliding assembly structure (the light source board and lampshade slide in from one side of the profile by opening the end cap) allows for manual assembly and disassembly, improving maintenance efficiency.

[0023] as follows:

[0024] Please see the appendix Figure 1-6 ,

[0025] The main structure includes a lamp tube body (1) consisting of a profile (10) and a lamp cover (14). The bottom of the profile (10) is provided with a base (13) that extends protruding into the profile (10) itself. The top side of the profile (10) is provided with an oblique mounting groove (100). A light source plate (1000) is provided inside the mounting groove (1000). The lamp cover (14) encapsulates the light source plate (1000) in the mounting groove (100). The profile (10) is provided with a dimming element (12) at the bottom near the mounting groove (100).

[0026] The working principle is as follows:

[0027] Traditional indoor recessed lighting fixtures are arranged in a straight line, causing the light source panel (1000) to be biased to one side of the lamp body. The light on the other side is blocked, forming a dark area that is difficult to eliminate, affecting the overall uniformity of lighting. In addition, the mounting base (13) is usually designed to be too narrow, making the lamp tubes very easy to tilt and tip over during placement or maintenance, resulting in poor stability. Its dimming switch is often installed on the back of the base (13), requiring users to struggle to find and operate it, resulting in a very poor user experience.

[0028] This technical solution features a wide base (13) extending outwards from the bottom of the profile (10), significantly increasing the contact area and support stability between the lamp tube and the mounting surface, effectively preventing accidental tipping or tilting of the lamp tube during installation, placement, or maintenance. Most importantly, a mounting groove (100) is obliquely positioned at the top of the profile (10) (e.g., at a 45° angle to the base (13)). The light source plate (1000) is encapsulated within this groove and covered by the lampshade (14). This oblique structure allows the light emitted by the light source to be projected directly into the outer space, completely covering areas prone to dark spots in traditional lamp tubes. It eliminates the need for wall reflection and minimizes contact with the wall, thus achieving a truly dark-free lighting effect after installation. The limiting clip (101) structure at the top of the mounting groove (100) has a lower second limiting part (1011) that securely holds the light source plate (1000), while the upper first limiting part (1010) closely engages with the clips (140) on both sides of the lampshade (14). A dimming element (12) is installed on the outer side of the profile (10) near the bottom of the mounting groove (100). Users can directly see and easily operate the switch to adjust the light without having to fumble around. The toothed light-diffusing surface (141) inside the lampshade (14) effectively diffuses the light, suppresses glare, and improves visual comfort. Assembly and maintenance are also very convenient. Simply open the end caps (11) at both ends of the profile (10), and the light source plate (1000) and lampshade (14) can be slid in or out from one side.

[0029] Reference Appendix Figure 4 In a preferred embodiment of the present invention: a limiting head (101) is formed on two opposite sides of the top of the mounting groove (100), a first limiting part (1010) for locking the lampshade (14) on both sides is formed on the upper part of the limiting head (101), and a second limiting part (1011) for limiting the light source board (1000) is formed on the lower part of the limiting head (101).

[0030] The assembly and disassembly process can be,

[0031] During assembly, open the end caps (11) at both ends of the profile (10), and push the light source plate (1000) horizontally into the inclined mounting groove (100) from one side of the profile (10). The bottom of the light source plate (1000) is automatically locked by the second limiting part (1011) of the limiting clip (101) in the mounting groove (100). Then, align the clips (140) on both sides of the lampshade (14) with the first limiting part (1010) at the top of the mounting groove (100) and press them down vertically until a "click" locking sound is heard. At this time, the lampshade (14) completely covers the light source plate (1000) to form an optical component. Finally, re-fasten the end caps (11) to both ends of the profile (10) to achieve overall dustproof sealing.

[0032] During disassembly, remove the end caps (11) at both ends of the profile (10), restore the operating entrance, pinch the edge of the lampshade (14) and pull it upwards to disengage the lampshade (14) clip (140) from the mechanical lock of the first limiting part (1010), separate the lampshade (14) to expose the light source plate (1000), slide the light source plate (1000) in the opposite direction along the mounting groove (100) track to disengage it from the locking constraint of the second limiting part (1011), and remove it completely from the side of the profile (10).

[0033] Reference Appendix Figure 5 In a preferred embodiment of this utility model, the lampshade (14) is provided with clips (140) on both sides for engaging with the first limiting part (1010).

[0034] Specifically, the latches (140) on both sides of the lampshade (14) form a precise snap-fit ​​with the first limiting part (1010) at the top of the mounting groove (100). When the lampshade (14) is assembled, the latches (140) on both sides slide in along the inclined surface of the first limiting part (1010), and achieve a "click" locking by generating a rebound force through deformation. The lampshade (14) of this solution can be a metal or plastic shell, and can be assembled by hand without tools.

[0035] Reference Appendix Figure 3 In a preferred embodiment of this utility model, the profile (10) is provided with end caps (11) at both ends, and the light source plate (1000) and lampshade (14) are slidably mounted on the profile (10) on one side by opening the end caps (11).

[0036] Specifically, the end cap (11) of this solution is set at both ends of the profile (10) to form an openable assembly channel. After opening the end cap (11), the through track inside the profile (10) is exposed. At this time, the light source board (1000) and the lamp cover (14) can be horizontally slid into the mounting groove (100) track from one side of the profile (10) (sliding in installation). The light source board (1000) is automatically locked and limited by the second limiting part (1011), and the lamp cover (14) is fastened and sealed with the first limiting part (1010) through the clip (140). Finally, the end cap (11) is closed to complete the overall dustproof seal.

[0037] Reference Appendix Figure 5 In a preferred embodiment of the present invention, the lampshade (14) is provided with a light-diffusing surface (141) for preventing light swirl, and the light-diffusing surface (141) is composed of raised tooth-like patterns.

[0038] In this scheme, the uniform light surface (141) inside the lampshade (14) is composed of raised tooth-like textures. These textures effectively eliminate glare by scattering and diffusing light, making the light output more uniform and soft, thereby greatly improving lighting comfort and visual experience.

[0039] Reference Appendix Figure 4 In a preferred embodiment of this utility model, the angle between the mounting groove (100) and the base (13) is 45°.

[0040] Specifically, the 45° angle between the mounting slot (100) and the base (13) in this solution allows the light emitted by the light source plate (1000) to be projected directly into the outer space at a lateral angle, completely covering the area where traditional lamp tubes are prone to dark areas. It does not rely on wall reflection and is kept as far away from the wall as possible, thereby achieving a dark-area-free lighting effect. At the same time, it minimizes light loss, improves the overall light efficiency uniformity and visual comfort, effectively eliminates dark area problems, and is suitable for various indoor dark slot environments.

[0041] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. Any equivalent structural transformations made using the contents of the present utility model specification and drawings under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
