Technical Field

[0001] The present invention belongs to the field of automotive lighting, and specifically relates to an automotive lighting optical system that realizes a spatial three-dimensional effect. Background Art

[0002] As an important optical system in automobiles, vehicle lights are the core functional modules that integrate road safety lighting and vehicle styling design. Traditional vehicle lighting technologies have undergone iterative upgrades from halogen lamps, xenon lamps to LED light sources, and gradually formed a technical route with a reflective optical architecture as the main body. Its basic components include core components such as a light source module, a main reflector, an auxiliary light distribution element, and an outer lens assembly. In the prior art, typical solutions usually adopt an optical design that combines a single reflecting surface and a Fresnel lens, and realize basic low beam / high beam functions through secondary light distribution control of the reflecting surface and beam shaping of the lens.

A resonant cavity is formed between the reflector and the semi-reflecting mirror. Among them, the semi-reflecting mirror is disposed at an acute angle with respect to the light emitted by the light source, and can form multiple layers of virtual images, realizing a three-dimensional effect of multi-angle observation. However, it cannot expand in the space in all directions of up, down, left, and right. Summary of the Invention

[0053] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0054] As Figures 1 - 5 shown, the present invention provides a vehicle lighting optical system for realizing a spatial three-dimensional effect, including: an image display screen 1, a first mirror, and a second mirror; the image display screen 1 is, for example, an LED display screen.

[0055] The image light of the image display screen 1 directly irradiates the observer;

[0056] The image light of the image display screen 1 irradiates the observer through the reflection of the first mirror and the second mirror;

[0057] The image light of the image display screen 1 irradiates the observer through the successive reflections of the first mirror and the second mirror;

[0058] The image light of the image display screen 1 irradiates the observer through the successive reflections of the second mirror and the first mirror.

[0059] The description of the present invention will continue as follows.

[0060] The present invention provides a vehicle lighting optical system for achieving a three-dimensional spatial effect, including: an image display screen 1, a first mirror, and a second mirror; the first mirror is a vertical mirror 2, and the second mirror is a horizontal mirror 3. Among them, both the vertical mirror 2 and the horizontal mirror 3 are perpendicular to the image display screen 1. The vertical mirror 2 and the horizontal mirror 3 are perpendicular to each other.

[0061] In a variant, any one or any combination of the three between the first mirror and the second mirror, between the first mirror and the image display screen 1, and between the second mirror and the image display screen 1 form an angle of 80 degrees to 100 degrees. For example, 81 degrees, 82 degrees, 83 degrees, 84 degrees, 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, or 99 degrees.

[0062] As Figure 6 shown, it is a schematic diagram of the virtual image formation of the vertical mirror 2 of the present invention. The image displayed on the image display screen 1 is reflected on the vertical mirror 2, and the reflected virtual image achieves a two-fold spatial expansion in the left-right direction visually, forming a lateral spatial expansion.

[0063] As Figure 7 shown, it is a schematic diagram of the virtual image formation of the horizontal mirror 3 of the present invention. The image displayed on the image display screen 1 is reflected on the horizontal mirror 3, and the reflected virtual image achieves a two-fold spatial expansion in the up-down direction visually, achieving a longitudinal spatial expansion.

[0064] As Figure 8 shown, it is a schematic diagram of the virtual image formation of the vertical mirror 2 and the horizontal mirror 3 of the present invention. The image displayed on the image display screen 1 is reflected on the vertical mirror 2, and the reflected virtual image is reflected again on the horizontal mirror 3. The image displayed on the image display screen 1 is reflected on the horizontal mirror 3, and the reflected virtual image is reflected again on the vertical mirror 2. The virtual images reflected by the vertical mirror 2 and the horizontal mirror 3 achieve a four-fold spatial expansion in the up-down, left-right directions visually, making the entire display effect present a three-dimensional state, that is, a lateral spatial expansion and a longitudinal spatial expansion are formed simultaneously.

[0065] By designing different light-emitting images on the image display screen 1, different three-dimensional spatial expansion effects can be achieved.

[0066] A simulated lighting effect is as Figures 9 - 12 shown, which is the display of an arrow image. The image display screen 1 displays a single arrow, and through the cooperation of the vertical mirror 2 and the horizontal mirror 3, two pairs of four arrow images facing each other are achieved in space.

[0067] Another simulated lighting effect is asFigures 13 - 16 As shown, it is the display of a snowflake image. The image display screen 1 displays a quarter of the snowflake image, and through the cooperation of the vertical mirror 2 and the horizontal mirror 3, a complete snowflake image can be realized in space.

[0068] There is also an analog lighting effect as Figures 17 - 20 As shown, it is the display of a spherical image. The image display screen 1 displays a quarter of the spherical image, and through the cooperation of the vertical mirror 2 and the horizontal mirror 3, a complete spherical image can be realized in space.

[0069] In more preferred examples, a display image with a three-dimensional effect can also be designed, and the image display screen 1 is made to display this three-dimensional effect design itself, presenting a more spatially three-dimensional display effect.
