Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] The embodiment of the present application provides a vehicle lamp lighting device and an automobile, which can solve the problem that in the related art, in order to realize the function of displaying corresponding characters and other elements in the vehicle lamp, it is difficult to popularize due to high technical difficulty and high cost.

[0026] See Figures 1 to 5As shown in the figure, an embodiment of the present application provides a vehicle lamp lighting device, including: a mask 1, a light source integration module 2, a reflector 3, and a reflective integration module 4. The mask 1 is set as a two-color injection molded mask 1. An installation cavity 10 is formed inside the mask 1, and a light transmission area 11 is provided on the mask 1; the light source integration module 2 is arranged in the installation cavity 10, and the light source integration module 2 is used to emit light sources; the reflector 3 is arranged in the installation cavity 10, and the focus of the reflector 3 is aligned with the light emitting point of the light source integration module 2. The reflector 3 is used to reflect the light source emitted by the light source integration module 2 into parallel light; the reflective integration module 4 is also arranged in the installation cavity 10, and the projection of the light transmission area 11 covers the reflective integration module 4. A grating unit 5 is provided on the reflective integration module 4. The grating unit 5 is used to display character elements. The parallel light reflected by the reflector 3 converges on the grating unit 5, and the grating unit 5 splits the converging light.

[0027] In this application, an installation cavity 10 is formed inside the mask 1 to provide an installation space, and the light transmission area 11 covers the reflective integration module 4 to ensure that the pattern of the grating unit 5 can be transmitted to the outside. When the light source integration module 2 emits light, the reflector 3 converts the light source into parallel light, and the parallel light converges on the grating unit 5 of the reflective integration module 4. The grating unit 5 splits the parallel light to form a locally high-contrast pattern, which is projected to the outside through the light transmission area 11. The light splitting effect of the grating unit 5 enables characters or patterns to have high contrast and clarity, meeting the regulatory requirements for the functionality of position lights. Compared with OLED technology, the mask 1, the light source integration module 2, the reflector 3, and the reflective integration module 4 applied in this application can all select economical and practical products. This solution has the advantages of low cost, high reliability, and mass production feasibility, providing a new technical path for the intelligent and personalized development of vehicle lamps.

[0028] For a clear and complete understanding of the grating unit 5, it should be specifically noted that the principle of the grating unit 5 reflecting and displaying images is mainly based on the diffraction and interference effects of light. Through specific micro-structure design, precise modulation of light is achieved, thereby forming characters or patterns.

[0029] In this application, the reflective integrated module 4 is rotatably connected within the installation cavity 10 and has a first rotational state and a second rotational state. Moreover, there are two sets each of the light source integrated module 2 and the reflector 3, with one set being adapted for installation in the first rotational state and the other set being adapted for installation in the second rotational state. Each state of the reflective integrated module 4 corresponds to the installation adaptation of a set of the light source integrated module 2 and the reflector 3, realizing the dynamic reconstruction of the optical system and meeting the functional requirements in different scenarios. In the first rotational state, the grating unit 5 of the reflective integrated module 4 can efficiently receive light and generate clear characters or patterns of the first type. Then, by adjusting the rotation angle of the reflective integrated module 4, different characters or patterns can be generated when the reflective integrated module 4 is in the second rotational state. Therefore, through the rotational connection design of the reflective integrated module 4 and the adaptation of the light source integrated module 2 and the reflector 3 in two rotational states, this application realizes the dynamic character display and optical performance optimization of vehicle lights, meets the functional requirements in different scenarios, and at the same time improves the interactivity, reliability, and cost-effectiveness of vehicle lights. Each set of the light source and reflector 3 modules is independently designed, facilitating installation, maintenance, and upgrade.

[0030] In this application, the provided reflective integrated module 4 includes: a substrate 40 and a reflective layer 41, where the substrate 40 is rotatably connected within the installation cavity 10; the reflective layer 41 is disposed on the substrate 40, and the reflective layer 41 includes, but is not limited to, an aluminum film disposed on the substrate 40, and the grating unit 5 is arranged on the reflective layer 41. The substrate 40 is installed within the installation cavity 10 in a rotatable connection manner, enabling it to have the ability to adjust the angle. By adjusting the tilt angle of the substrate 40, the orientation of the reflective layer 41 and the grating unit 5 can be changed, thereby changing the display direction, brightness, or shape of the characters or patterns. The core principle is to utilize the angle adjustment of the substrate 40 to change the incident light conditions of the grating unit 5, thereby controlling the display effect of the characters or patterns. This enables the technical solution of this application to not only achieve character display but also be dynamically adjustable to realize the display of more types of characters. It provides a new technical path for the intelligent and personalized development of vehicle lights.

[0031] In this application, by arranging in the installation cavity 10 including but not limited to a servo motor 6, the servo motor 6 is connected to the substrate 40 and is used to control the rotation of the substrate 40 to adjust to the first rotation state and the second rotation state. First of all, the servo motor 6 can accurately control the rotation angle and speed of the substrate 40 to ensure the accuracy and stability of the switching between the first rotation state and the second rotation state of the reflective integrated module 4. In addition, the servo motor 6 can be connected to the control system of the vehicle to receive instructions. So that the servo motor 6 can adjust the rotation state of the substrate 40 in real time according to the input signal. The high response speed enables the substrate 40 to complete the state switching in a short time. For example, corresponding warning characters can be quickly displayed when the vehicle turns or brakes. Compared with manual or simple mechanical structures, the servo motor 6 can reduce mechanical errors and jitters during the rotation process, ensuring that the substrate 40 can reach the predetermined accurate position every time it switches.

[0032] In this application, in order to enable the substrate 40 to display two different types of character elements when rotating to the first rotation state and the second rotation state, two groups of grating units 5 are provided on the reflective layer 41, and the character types of the two groups of grating units 5 are different. Specifically: the provided grating unit 5 includes a bottom image layer 50 and an upper grating layer 51. Among them, the bottom image layer 50 is arranged on the reflective layer 41, and the upper grating layer 51 is arranged on the bottom image layer 50; and the bottom image layer 50 and the upper grating layer 51 corresponding to the two groups of grating units 5 are located on different planes. Among them, the bottom image layer 50 serves as the basis for grating spectroscopy, and its image content determines the semantics of the finally displayed characters or patterns. The bottom image layer 50 is used to carry the original image information of characters, symbols or patterns, and forms high-contrast image areas by using processes including but not limited to printing, etching or coating; the upper grating layer 51 is superimposed on the bottom image layer 50, and the incident light is split and modulated through microstructures including but not limited to periodic lines, grooves or diffraction gratings. The microstructure of the grating layer decomposes the light of the bottom image layer 50 into light in different directions or wavelengths, thereby generating characters or patterns with specific visual effects.

[0033] The light source integration module 2 emits light, which is shaped by the reflector 3 and then incident on the reflective layer 41. The reflective layer 41 efficiently reflects the light to the bottom image layer 50. The bottom image layer 50 preliminarily modulates the light to form the contour light intensity distribution of characters or patterns. After passing through the bottom image layer 50, the light enters the upper grating layer 51. The microstructures of the grating layer diffract or interfere with the light, further modulating the light intensity distribution to generate the final displayed visual effect. The bottom image layer 50 and the upper grating layer 51 of the two groups of grating units 5 are located in different planes, allowing the character elements to be designed separately to achieve multi-mode display. By controlling the rotation of the substrate 40 with the servo motor 6, the reflective integration module 4 is switched between the first rotation state and the second rotation state. In the first rotation state, the plane of the first group of grating units 5 is adapted to the light source integration module 2 and the reflector 3 to display the first type of characters; in the second rotation state, the plane of the second group of grating units 5 is adapted to the light source to display the second type of characters. Through simple microstructure design and hierarchical layout, a multi-mode display function with low cost and high reliability is achieved.

[0034] In this application, the provided light source integration module 2 includes: a PCB board 20 and LED particles 21. The LED particles 21 are arranged on the PCB board 20, and the focal projection of the LED particles 21 coincides with that of the reflector 3. The PCB board 20 is fixed at the bottom of the installation cavity 10, and the vertical projection of the reflector 3 covers the PCB board 20, ensuring that the light emitted by the LED particles 21 can be efficiently captured and directionally reflected by the reflector 3. Also, through the coincidence of the foci, the reflector 3 can concentrate and directionally project the light emitted by the LED particles 21 to the reflective integration module 4 to generate high-brightness characters or patterns, enhancing the visual effect and recognition of the vehicle lamp.

[0035] In this application, the reflecting surface of the reflector 3 is set as a parabolic surface, so that the light emitted from the focal position forms a parallel light beam after reflection. Therefore, the focal projection on the parabolic surface of the reflector 3 coincides with the light-emitting point of the light source integration module 2, and the light emitted by the LED particles 21 is efficiently captured and directionally projected to the reflective integration module 4 by the reflector 3. The focusing characteristic of the parabolic reflector 3 enables the light to be projected with high intensity and over a long distance to generate high-brightness characters or patterns, enhancing the visual effect and recognition of the vehicle lamp, especially prominent in nighttime or low-light environments. In addition, an aluminized layer 30 is provided on the parabolic surface of the reflector 3. Aluminum has the characteristic of high reflectivity and can effectively reflect the light in the visible light band, reducing the absorption and loss of light energy.

The reflector 3 is used for reflecting the light source emitted by the light source integration module 2 into parallel light; the reflective integration module 4 is also arranged in the installation cavity 10, and the projection of the light-transmitting area 11 covers the reflective integration module 4. A grating unit 5 is provided on the reflective integration module 4. The grating unit 5 is used for displaying character elements. The parallel light reflected by the reflector 3 converges on the grating unit 5, and the grating unit 5 splits the converging light. When the light source integration module 2 emits light, the reflector 3 converts the light source into parallel light, and the parallel light converges on the grating unit 5 of the reflective integration module 4. The grating unit 5 splits the parallel light to form a locally high-contrast pattern, which is projected to the outside through the light-transmitting area 11. The splitting effect of the grating unit 5 enables characters or patterns to have high contrast and clarity. Compared with the OLED technology, the mask 1, the light source integration module 2, the reflector 3, and the reflective integration module 4 applied in the present application can all select economical and practical products. This solution has the advantages of low cost, high reliability, and mass production feasibility, providing a new technical path for the intelligent and personalized development of vehicle headlights.
