Abstract
Description
Technical Field
[0001] This utility model relates to lighting tubes, and more particularly to an anti-glare optical tube. Background Technology
[0002] In the field of modern lighting, the performance and visual comfort of luminaires have always been key concerns. As people's demands for visual health and lighting quality continue to rise, the glare problem inherent in traditional lighting fixtures is becoming increasingly prominent.
[0003] Common light tubes on the market, such as ordinary fluorescent tubes and LED tubes, typically emit light by exciting gas or semiconductor materials with electrodes. During the light emission process, the light is emitted directly from the tube's surface, resulting in a relatively dispersed light intensity distribution, and the light travels from various angles. When the human eye looks directly at the tube from any direction, or when the contrast between the tube's light and the surrounding ambient light is too high, glare is likely to occur. Furthermore, due to the dispersed light, a large portion of the light cannot be used to illuminate the effective area, leading to low efficiency.
[0004] Glare not only reduces lighting effectiveness but can also cause discomfort to the eyes, and even lead to visual fatigue and safety hazards. Therefore, developing a light tube that can effectively prevent glare is of significant practical importance. Utility Model Content

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0034] like Figure 1 This embodiment provides an anti-glare optical tube, including a long strip-shaped tube body 3; the tube body 3 includes a mounting base 2 and a lampshade 1, the lampshade 1 being connected to the mounting base 2 to form a receiving cavity 31; the mounting base 2 is used to set a light source assembly 4 and place the light source assembly 4 inside the receiving cavity 31; the lampshade 1 includes a main light-emitting part 11 located directly below the light source assembly 4, and microstructure parts 12 disposed on both sides of the main light-emitting part 11; the microstructure parts 12 are respectively connected to the main light-emitting part 11 and the mounting base 2.
[0035] like Figure 2 The mounting base 2 has a centrally located mounting groove 21, and the light source assembly 4 is disposed in the mounting groove 21. The mounting base 2 serves as the mounting carrier for the light source assembly 4, and the light source assembly 4 is fixed to the mounting base 2 via the mounting groove 21. The light-emitting surface of the light source assembly 4 faces the lampshade 1, which is made of transparent or semi-transparent material. A diffusing agent can be added to the material during the lampshade manufacturing process to allow light to pass through smoothly.
[0036] The main light-emitting part 11 has a smooth arc-shaped structure, resembling a curved arc. This arc design allows the main light-emitting part 11 to form a light-emitting surface with a certain curvature in space. The arc structure optimizes the direction of light emission, reducing the amount of light directly entering the human eye and thus reducing the possibility of glare.
[0037] The arc length of the main light-emitting part 11 accounts for 15%-20% of the total circumference of the lamp tube body 3. In this embodiment, preferably, the arc length of the main light-emitting part 11 accounts for 17% of the total circumference of the lamp tube body 3 to ensure sufficient light-emitting area.
[0038] like Figure 3The microstructure 12 includes a first serrated structure 121 and a second serrated structure 122. The first serrated structure 121 is located on the inner wall surface of the lampshade 1, and the second serrated structure 122 is located on the outer wall surface of the lampshade 1. The first serrated structure 121 and the second serrated structure 122 are arranged opposite to each other, and the serrations of the first serrated structure 121 and the second serrated structure 122 are in the same direction, with the tips of the serrations facing the main light-emitting part 11.
[0039] The design of the first sawtooth structure 121 and the second sawtooth structure 122 is used for focusing light and preventing glare. The sawtooth structure guides the light emitted by the light source component 4 in the direction toward the main light source 11 through refraction and reflection, thereby achieving light focusing. At the same time, the sawtooth structure can scatter and slowly reflect the light, making the light softer and reducing the strong light that directly hits the human eye, thereby reducing glare.
[0040] like Figure 4 Specifically, the sawtooth structure is such that, along the direction extending from the main light-emitting part 11 to the mounting base 2, the sawtooth angles a1 of the first sawtooth structure 121 and a2 of the second sawtooth structure 122 both increase in a gradient. Sawtooth angles a1 and a2 are the angles between the inclined surface of each sawtooth and the central axis of the lamp tube. The angle increase range of a1 and a2 is 8°-10°, preferably increasing in a gradient of 9°. This gradient angle design of the sawtooth structure effectively controls the direction of light propagation, allowing light to be reflected and refracted to varying degrees at different positions, resulting in uniform light distribution at different angles and reducing glare. Through the increasing sawtooth angles and spacing, progressive light focusing can be achieved, preventing the light from being too concentrated or dispersed.
[0041] The first sawtooth structure 121 includes a plurality of first sawtooths 1211, and the second sawtooth structure 122 includes a plurality of second sawtooths 1221; the sawtooth angle a1 of the first sawtooth 1211 corresponding to the position is smaller than the sawtooth angle a2 of the second sawtooth 1221.
[0042] Both the first sawtooth 1211 and the second sawtooth 1221 include a first side 123 and a second side 124. The first side 123 is an inclined surface used to form the sawtooth, and the second side 124 is used to connect two connected first sides 123. Figure 4 The angle between the extension line of the first side 123 of the first sawtooth 1211 and the extension line of the second side 124 of the second sawtooth 1221 is 60°-80°, and the preferred angle b is 70°.
[0043] The first sawtooth 1211 and the second sawtooth 1221 are triangular in shape with sharp tops. The bottoms of the first sawtooth 1211 and the second sawtooth 1221 are connected to the inner wall and the outer wall of the lampshade 1, respectively. The first sawtooth 1211 and the second sawtooth 1221 use the change in wall thickness at the top to cause light to be refracted when passing through regularly different wall thicknesses, thereby changing the direction of light propagation.
[0044] like Figure 5 The first sawtooth structure 121 initially refracts and reflects the light emitted from inside the lamp tube. The light's propagation direction is altered to varying degrees at different positions, forming the desired refraction path through the tube wall. Excess light forms complex reflection paths inside the lamp tube, thus achieving an initial uniform distribution of light. The second sawtooth structure 122 further refracts and diffuses the light processed by the first sawtooth structure 121, further altering its propagation direction according to different positions and focusing the light towards the main light-emitting part 11. This synergistic effect of the inner and outer sawtooth structures allows the light emitted from the lamp tube to be refracted and reflected multiple times during propagation, changing the light's propagation direction and intensity distribution. This effectively improves light utilization and reduces the direct intensity of light emitted from ineffective areas, preventing glare from direct light entering the eyes and avoiding waste of ineffective light, thereby improving energy efficiency.
[0045] like Figure 5 The first serrated structure 121 and the second serrated structure 122 are respectively connected to the main light-emitting part 11 and the mounting base 2. The microstructure parts 12 on both sides of the main light-emitting part 11 are symmetrically arranged. The first serrated teeth 1211 and the second serrated teeth 1221 of the first serrated structure 121 and the second serrated teeth 1221 near the mounting base 2 cooperate to refract light into the effective lighting space. The synergistic effect of the first serrated teeth 1211 and the second serrated teeth 1221 near the mounting base 2 allows the light emitted by the lamp tube to illuminate the effective space more effectively, avoiding the problem of resource waste.
[0046] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
