Specifically, linear lamps have a lot of products with different optical angles, but different optical angles may be required to meet the lighting needs in the same scene. That is, traditional lamps and existing dimmable lamps often need to increase the number of lamps or replace lamps of different specifications to meet the changing lighting needs, which not only increases costs, but also causes waste of resources and inconvenience in installation and maintenance. Summary of the invention
[0004] In order to improve the performance of traditional lamps and existing dimmable lamps in response to changing lighting needs, it is necessary to increase the number of lamps or replace lamps of different specifications, which not only increases costs, but also causes waste of resources and inconvenience in installation and maintenance. The present application provides an adjustable linear optical structure and a mold device thereof, which can achieve good dimming effects, can realize changes in different optical angles on the same lamp, meet different optical needs in the same application scenario, reduce the number of lamps installed, achieve lighting effects while achieving energy conservation and emission reduction.

DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-9 This application is described in further detail.
[0036] In a first aspect, embodiments of the present application disclose an adjustable light linear optical structure.
[0037] Embodiment 1: A linear optical structure with adjustable light, see Figure 1 and Figure 2 , including a shell, a first light-transmitting body 1, and a second light-transmitting body 2, the shell is used to bear the load; the first light-transmitting body 1 is installed in the shell; the second light-transmitting body 2 is slidably installed on the shell, and the second light-transmitting body 2 is located below the first light-transmitting body 1; the first light-transmitting body 1 has a light source accommodating portion 11, and the light source accommodating portion 11 is located on a side of the first light-transmitting body 1 away from the second light-transmitting body 2.
[0038] Specifically, the light source accommodating portion 11 is a hemispherical body protruding from the surface of the first light-transmitting body 1 and is integrally formed with the first light-transmitting body 1; the light source accommodating portion 11 has a trapezoidal cavity for accommodating the light source, and the trapezoidal cavity is used to adapt to the appearance of the light source to improve the stability of placing the light source.
[0039] See also Figure 1 and Figure 2 Further, the first light-transmitting body 1 has a width B, the light source accommodating portion 11 has a diameter L, the displacement of the second light-transmitting body 2 is D, and D≤L, and the length of the diameter L has a value range of
[0040] The displacement D of the second light-transmitting body 2 is less than or equal to the diameter L of the light source accommodating portion 11. The value range of the diameter L of the light source accommodating portion 11 is two-tenths to three-tenths of the width B of the first light-transmitting body 1, which is an effective range for the light beam to achieve polarization through the second light-transmitting body 2; when the displacement of the second light-transmitting body 2 exceeds the diameter L of the light source accommodating portion 11, the amount of refraction of the light beam by the second light-transmitting body 2 is extremely low, so that the polarization effect cannot be achieved, the light beam angle will be uncontrollable, and it is difficult to maintain a good lighting brightness.
[0041] See also Figure 1 and Figure 2 Furthermore, the first light-transmitting body 1 has a first refractive portion 12, which is used to disperse light; the second light-transmitting body 2 has a second refractive portion 21, which is used to correct light; the movement path of the light beam, the light beam enters the first light-transmitting body 1, the light beam is scattered by the first refractive portion 12 of the first light-transmitting body 1, the scattered light beam enters the second light-transmitting body 2, and the light beam is corrected by the second refractive portion 21 of the second light-transmitting body 2, thereby achieving the effect of forward light emission.
[0042] The process of adjusting the lighting angle: move the second light-transmitting body 2, the second refractive portion 21 of the second light-transmitting body 2 is away from the first refractive portion 12 of the first light-transmitting body 1, and the light beam passes through the second light-transmitting body 2. Because there is no correction by the second refractive portion 21, the light beam is polarized, and the angle of the light beam changes, so that the angle of the light beam changes when it is emitted through the second refractive portion 21 of the second light-transmitting body 2. While the brightness is maintained, the irradiation range or irradiation point changes. This method adjusts the optical angle by moving the light-transmitting body, and has the advantages of simple structure, easy operation, and low cost. Compared with the need to additionally develop a mechanical structure dedicated to adjusting the angle, and the need to change the power of the light source to maintain the lighting brightness, it has higher cost performance, higher flexibility and energy saving, and the lighting effect is more diverse.
[0043] See also Figure 1 and Figure 2 Further, the first refractive portion 12 and the second refractive portion 21 are respectively sawtooth shaped, and the first refractive portion 12 and the second refractive portion 21 are meshed with each other.
[0044] Specifically, the sawtooth shape of the first refractive portion 12 is specifically a convex block convexly provided on the surface of the first light-transmitting body 1, and is integrally formed with the first light-transmitting body 1; the sawtooth shape of the second refractive portion 21 is specifically an inclined surface provided on the second light-transmitting body 2. The first refractive portion 12 and the second refractive portion 21 are configured in a sawtooth shape, which can change the propagation path of the light, generate scattering, refraction or diffraction, and after the first refractive portion 12 and the second refractive portion 21 are combined, the first refractive portion 12 scatters the light beam, and then enters the second lens through the second refractive portion 21, thereby correcting the light beam, achieving stable lighting and maintaining stable lighting efficiency, and also reducing shadows.
[0045] The first light-transmitting body 1 and the second light-transmitting body 2 are TIR lenses, and the full name of TIR lens is Total Internal Reflection Lens, i.e., total internal reflection lens. TIR lens has the advantages of high efficiency and high temperature resistance, small size, light weight and low preparation cost. By utilizing these advantages, the combination of the first light-transmitting body 1 and the second light-transmitting body 2 can adjust the light accordingly in terms of focusing, parallelization and divergence, thereby adjusting the light distribution effect and the shape of the light spot, meeting the dimming requirements in various different scenes, reducing the number of lamps installed, achieving lighting effects while realizing energy conservation and emission reduction, and the curvature of the first light-transmitting body 1 is variable, which is specifically determined according to the scene of application.
[0046] In this embodiment, the light emitted by the light source is a Lambertian distribution of a near-surface light source, assuming that the surface of the light source is diffusely reflective, that is, each point on the surface of the light source radiates light uniformly in all directions. The distribution model of Lambertian distribution is very effective in describing the radiation characteristics of diffuse reflective materials, which is helpful for understanding the radiation intensity of light, so as to accurately place the position and direction of the light source; and the TIR lens is obtained by rotating multiple Bezier (Bezier curve or Bezier curve) curves 360° around the midline axis. By adjusting the shape of the Bezier curve and the position of the control point, the optical performance of the lens can be optimized. For example, by changing the curvature of the curve, the divergence angle of the light beam can be adjusted to meet specific lighting requirements.
[0047] Embodiment 2: The difference between this embodiment and the first embodiment lies in the difference of the second lens. For details, see Figure 1 and Figure 3 A diamond-shaped convex portion 23 is provided on the side of the second light-transmitting body 2 away from the first light-transmitting body 1, and a plurality of diamond-shaped convex portions 23 are provided; and the surface of the diamond-shaped convex portions 23 is roughened.
