Description

Technical Field

[0001] This invention relates to the field of automotive lighting system manufacturing technology, and more particularly to an ambient lighting optical system. Background Technology

[0002] Currently, large areas of car dashboards, door panels, and other interior surfaces are often equipped with ambient lighting. However, these ambient lighting patterns are generally two-dimensional and fixed. Even dynamic ambient lighting only changes in brightness and color; the fundamental graphic remains the same. But with advancements in technology and evolving aesthetic tastes, consumers are demanding greater richness in the effects of automotive interior ambient lighting. Fixed-pattern ambient lighting will no longer be sufficient to meet their needs.

[0003] Currently, mainstream ambient lighting with surface light sources typically comes in two forms. Figure 1 A schematic diagram of the structure of an ambient light in the prior art is shown. As shown, this ambient light consists of a light guide, a PCB with a light source, a light guide bracket, and a mask. Figure 2 A schematic diagram of another ambient light in the prior art is shown. As shown, this ambient light consists of a PCB, a light guide, a bracket, a light-diffusing film, and a patterned mask. An LED array is provided on the PCB. The patterned outer shell is a multi-layered structure, such as an IMD shell, a TPO skinned shell, and a perforated skinned shell. Figure 3 A schematic diagram of the structure of an IMD enclosure in the prior art is shown. As shown, this enclosure includes, from the inside out, a PC substrate, multiple protective layers, two black paint layers, a translucent paint layer, a PC layer, and a UV protective layer.

As shown, this type of shell includes, from the inside out, a 2K (two-material injection molded) substrate layer, a 3DMesh layer, a fabric layer, and a TPO light-transmitting layer. Figure 5 A schematic diagram of a perforated skin shell in the prior art is shown. As shown, this type of shell includes, from the inside out, a 2K substrate layer, a 3DMesh layer, a fabric layer, and a perforated skin layer.

[0004] It is obvious that existing ambient lighting (optical systems) have the following problems:

[0005] 1. It can only achieve dynamic effects at the color and brightness levels, and cannot achieve changes in graphics;

[0006] 2. To achieve graphic changes, a large number of LEDs are needed, which results in high control costs and significant heat generation, requiring additional consideration of heat dissipation structures;

[0085] Figure 6 A schematic diagram of the structure of an ambient lighting optical system according to an embodiment of the present invention is shown. Figure 7 An exploded view of an ambient lighting optical system according to an embodiment of the present invention is shown. As shown, the present invention provides an ambient lighting optical system 601, which mainly includes a light-transmitting mask 602, a light source unit 603, a graphic unit 604, a mirror unit 605, and a control unit 606.

[0086] The light-transmitting mask 602 has a display area on its surface, which has a light-transmitting structure. The rest of the light-transmitting mask 602 is made of opaque material. The light-transmitting mask 602 has a dual-light-path coating.

[0087] The light source unit 603 includes LEDs, which can be tri-color LEDs or monochromatic LEDs;

[0088] The graphic unit 604 includes a light guide 607 and a diffuser 608. The light guide 607 is enveloped by the diffuser 608, and the light-incident end of the light guide 607 is connected to the LED.

[0089] The mirror unit 605 includes a combined mirror 609, and the graphic unit 604 is arranged between the light-transmitting mask 602 and the combined mirror 609.

[0090] The control unit 606 includes a first PCB 610 and a mirror adjuster 611. The first PCB 610 adjusts the combined mirror 609 via the mirror adjuster 611 to change the angle and distance between the combined mirror 609 and the graphics unit 604.

[0091] like Figure 6 As shown, along the arrow direction, the control unit 606 controls the light source unit 603 to emit light. The light projects the graphic generated by the graphics unit 604 onto the mirror unit 605, and then through the light-transmitting mask 602 to reach the human eye. In other words, the human eye can see the dynamic graphic through the display area. The control unit 606 is mainly used to control the light source unit 603 and the mirror unit 605. Specifically, the control unit 606 controls the light source unit 603 to change the color and / or brightness of the light source to achieve changes in color and / or brightness. The control unit 606 controls the mirror unit 605 to adjust the angle and distance between the combined mirror 609 and the graphics unit 604, thereby forming a dynamic graphic. By way of example and not limitation, the control unit 606 can also control the graphics unit 604 to adjust the distance between the graphics unit 604 and the mirror unit 605 to generate a dynamic graphic. Therefore, the ambient lighting optical system 601 provided by this invention can generate dynamic graphics, enriching the performance of ambient lighting and enhancing the user experience.

[0092] Figure 8 A schematic diagram of mirror imaging in the prior art is shown. Figure 1 . Figure 9 A schematic diagram of mirror imaging in the prior art is shown. Figure 2 . refer to Figure 8The main principle of this invention is as follows: An object A is placed between two parallel plane mirrors. Object A forms a virtual image on the mirror surface, which can be called a first-order virtual image A1. Simultaneously, the mirror surface and the first-order virtual image A1 form an image in the other mirror, resulting in a second-order virtual image A2. In this way, as long as the mirror surface is large enough, the human eye can observe an infinite number of images. It is easy to understand that when the distance between object A and the mirror surface is changed, the spacing between the images also changes. (Reference) Figure 9 It is not difficult to see that when the angle of the plane mirror is changed, the position of the image changes, or in other words, the geometric distribution of the image changes. In this invention, the light source unit 603 forms a pattern through the pattern unit 604, and the pattern is reflected by the mirror unit 605 and the dual-light path coating 615 of the light-transmitting mask 602 (equivalent to two plane mirrors in the prior art), generating an image arranged in a certain set pattern. Passengers inside the vehicle can observe the image of the ambient light (dynamic graphics) in the display area.

[0093] Preferably, the ambient lighting optical system 601 also includes a cover plate 612. The cover plate 612 is fixedly fitted to the light-transmitting mask 602, forming a space between them to accommodate the light source unit 603, the graphic unit 604, the mirror unit 605, and the control unit 606.

[0094] refer to Figure 7 The graphic unit 604 is fixed to the inside of the light-transmitting mask 602. The LED is soldered and fixed to the first PCB 610. The mirror adjuster 611 is fixed to the first PCB 610, and the first PCB 610 is mounted and fixed to the cover plate 612 to form a stable structure.

[0095] Preferably, the light-transmitting mask 602 is manufactured using IMD (In-Mold Decoration) technology. The light-transmitting mask 602 includes a light-transmitting film 613, on which a display area is formed.

[0096] Figure 10 A schematic diagram of the transparent film structure of a light-transmitting mask according to an embodiment of the present invention is shown. As shown, the light-transmitting film 613 has a stacked structure, including a first protective layer 614, a dual-light-path coating 615, an ink layer 616, a PC substrate 617, and a second protective layer 618 arranged sequentially from the inside out (from left to right in the figure). The dual-light-path coating 615 is light-transmitting on the side facing the second protective layer 618 and reflective on the other side. That is, the dual-light-path coating 615 has a reflective effect on the side near the graphics unit 604, so that the graphics generated by the graphics unit 604 are located between the mirror unit 605 and the dual-light-path coating 615, thereby forming multiple virtual images of the graphics through the principle of reflection, arranged in a certain aggregate pattern. Passengers inside the vehicle can observe the graphics including these multiple virtual images in the display area.

[0097] Figure 11 A schematic diagram illustrating the maximum allowable rotation angle of the combined mirror 609 according to an embodiment of the present invention is shown. As shown, the maximum allowable rotation angle of the combined mirror 609 is related to the boundary of the display area reached by the human eye's visual line. The boundary of the display area reached by the human eye's visual line corresponds to the maximum boundary of the light guide 607 reached by the human eye. The angle of incidence of the human eye's visual line is the angle α formed between the human eye's visual line and the display area. Therefore, the maximum rotation angle α' of the combined mirror 609 is the supplementary angle of the angle α, which is 90° - α. The dashed line in the figure represents the initial position of the combined mirror 609, which is substantially parallel to the light-transmitting film 613 or the dual-beam path coating 615 of the light-transmitting mask 602.

(Reference) Figure 12 The combined mirror 609 is in its initial position, substantially parallel to the light-transmitting mask 602. The diffuser 608 is illuminated by the light guide 607 and will repeatedly image onto the dual-optical-path coating 615 of the combined mirror 609 and the light-transmitting mask 602. (Reference) Figure 13 The human eye can see a pattern containing multiple images by looking through the light-transmitting film 613 along the visual line.

(Reference) Figure 14 The control unit 606 controls the rotation angle of the combined mirror 609, causing the combined mirror 609 to tilt to the left from its initial position on the map. The diffuser 608 is illuminated by the light guide 607, repeatedly imaging onto the dual-optical-path coating 615 of the combined mirror 609 and the light-transmitting mask 602. (Reference) Figure 15 The human eye can see a pattern containing multiple images by looking through the light-transmitting film 613 along the visual line, relatively Figure 13 The graphic has changed significantly.

[0100] Preferably, the composite mirror 609 includes at least two plane mirrors. By way of example and not limitation, the composite mirror 609 can be composed of more plane mirrors. The more plane mirrors there are, the more complex the graphic effects can be, the stronger the sense of spatial volume, and thus the richer the visual experience.

[0101] Figure 16 A schematic diagram of another embodiment of the present invention is shown. Figure 17 yes Figure 16 Visual renderings. (Reference) Figure 16In this embodiment, the combined mirror 609 is composed of two plane mirrors. The control unit 606 controls the rotation angle of the two plane mirrors respectively. The combined mirror 609 rotates downward along the initial dotted line position, and the two plane mirrors form an angle. The diffuser 608 is lit by the light guide 607, and images are repeatedly formed on the dual-optical-path coating 615 of the combined mirror 609 and the light-transmitting mask 602. (Reference) Figure 17 The human eye can see the changing goose pattern through the light-transmitting film 613 along the visual line. This pattern contains multiple images, relatively... Figure 13 and 15 The graphic changes more noticeably, creating a sunken effect and a stronger sense of three-dimensionality.

[0102] Preferably, diffuser 608 is made using 2K injection molding or spray painting laser engraving to create a pattern on its surface. The pattern can be geometric shapes, designs, or ornamentation, offering a wider range of content. Figure 18 A schematic diagram of a diffuser 608 according to another embodiment of the present invention is shown. Figure 19 Based on Figure 18 Visual renderings. (Reference) Figure 18 This displays a geometric pattern formed on the surface of the diffuser 608. (Reference) Figure 19 The human eye can see multiple images of patterns through the light-transmitting film 613 along the visual line.

The film 619 is positioned between the combined mirror 609 and the light guide plate 620, and the light guide plate 620 is positioned between the film 619 and the mirror adjuster 611. The light guide plate 620 is connected to the second PCB 621. The light guide plate and the second PCB 621 can be fixed to the mirror adjuster 611. It is easy to understand that the light guide plate 620 is illuminated by the light source of the second PCB 621, causing the image of the film 619 to be superimposed on the image of the diffuser 608, generating a superimposed effect. Figure 22 This is an overlay effect diagram of a film and a diffuser according to another embodiment of the present invention. If the film 619 has a wavy pattern and the combined mirror 609 is in the initial position, the human eye can see through the light-transmitting film 613 along the visual line.
