[0002] The automobile lamp can be used for vehicle exterior lighting, vehicle lamp lighting, signal identification, and atmosphere effect, etc. The automobile lamp plays a relatively important role in vehicle driving safety and intelligent cabin, etc. In recent years, the automobile lamp is using light guide technology. The light guide technology is a kind of vehicle lamp optical technology capable of overall lighting of the light guide. The core parts of the technology mainly include a light guide and a circuit board. The light guide is usually tubular. The circuit board is generally arranged at one end of the light guide. The circuit board is provided with light sources. When a plurality of light sources are arranged, the plurality of light sources are usually uniformly arranged around the normal central line of the light guide light entry surface. The light emitted by the light source enters the light guide from the light guide light entry surface. Figure 1 The surface of the light guide 1' close to the mounting portion is provided with a plurality of light guide teeth 2'. The surface away from the mounting portion is a light exit surface. The inner fittings 3 and 4 are optionally arranged outside the light exit surface. The outer fittings 5 and 6 are arranged outside the inner fittings. The light is guided through the light guide teeth 2' of the light guide 1', and then passes through the inner fittings 3 and the outer fittings 5 in sequence, thereby forming a uniformly lit strip-shaped light emitting effect.

[0003] However, in the light guide technology, the light guide is emitted through the inner fittings 3 and the outer fittings 5. When observed from the outside to the inside of the automobile lamp, the structure of the light guide is easy to be seen. The light emitting area is the light exit surface of the light guide.

The height difference between the end point H and the intersection point B in the second direction is greater than or equal to 0.5 mm, and the height difference between the intersection point C and the end point G in the second direction is greater than or equal to 0.5 mm.

[0010] In a preferred embodiment of the present application, the light-transmitting region of the second optical element has a base surface, the optical pattern is arranged on the base surface, and the illumination range is located within the base surface, and in a cross section formed by the first light-emitting direction and the second direction, the end of the base surface close to the first optical element is point A, and the end of the base surface away from the first optical element is point D. The height difference between endpoint A and intersection point C in the second direction is greater than or equal to 2 mm; and the height difference between intersection point B and endpoint D in the second direction is greater than or equal to 2 mm.

[0011] In a preferred embodiment of this application, the surface of the second optical element is convex to form the optical pattern, or the surface of the second optical element is concave to form the optical pattern.

[0012] In a preferred embodiment of this application, the second optical element is an optical element manufactured using CNC machining technology, or the optical element is an optical element manufactured using mold injection molding technology.

[0013] In a preferred embodiment of this application, the first optical element is a light guide, and the optical assembly further includes a light source disposed at the end of the light guide.

[0014] In a preferred embodiment of this application, the light guide has light guide teeth extending along the axial direction of the light guide. After the light emitted from the light source enters the light guide, it illuminates the light guide teeth and is reflected by the light guide teeth before exiting from the first light-emitting surface of the light guide. The line connecting the light guide teeth and the center of the light guide forms an angle greater than 0 degrees with the first light-emitting direction.

[0015] In a preferred embodiment of this application, the first optical element is a thick-walled or reflective mirror.

[0017] Based on the same concept, this application also provides a vehicle including the aforementioned automotive lamps.

[0018] Because this application adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: The optical component provided in this application includes a first optical element and a second optical element. The second optical element includes a light-transmitting area and a non-light-transmitting area. An optical pattern is provided in the light-transmitting area. Light emitted from the first optical element is projected onto the optical pattern of the second optical element. The optical component has a first light-emitting direction and a second direction perpendicular to the first light-emitting direction. The first optical direction and the light-transmitting area of ​​the second optical element are offset in the second direction, so that in the direction opposite to the first light-emitting direction, the second optical element is blocked by the non-light-transmitting area of ​​the first optical element, thus hiding the first optical element. At the same time, when the optical component is viewed from the opposite direction of the first light-emitting direction, only the visual effect of floating and lit points at the optical pattern can be observed.

The non-transparent areas of the light-shielding member and the second optical element are used to block part of the light from the first optical element. Due to the blocking by the light-shielding member and the non-transparent areas of the second optical element, a light-transmitting gap is formed in the light-emitting area of ​​the first optical element. The light emitted from the first optical element shines on the optical pattern through the light-shielding area, and the lighting effect of the optical pattern is suspended on the surface of the second optical element.

Detailed Implementation

[0023] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed description of an optical component and automotive lighting fixture proposed in this application. Identical or similar reference numerals denote identical or similar components. The following description of this application with reference to the accompanying drawings is intended to explain the overall concept of this application and should not be construed as a limitation thereof.

[0024] According to the overall concept of this application, an optical component is provided for use in vehicle lighting. The optical component has a first light emission direction and includes a first optical element and a second optical element. The second optical element includes a light-transmitting area and a non-light-transmitting area. The second optical element has an optical pattern in the light-transmitting area. The light emitted from the first optical element is projected onto the optical pattern of the second optical element to form a suspended illuminated area in the region where the optical pattern is located; Wherein, the light-transmitting areas of the first optical element and the second optical element are staggered in a second direction, so that in a direction opposite to the first light-emitting direction, the first optical element is blocked by the non-light-transmitting area of ​​the second optical element; the second direction is perpendicular to the first light-emitting direction.

[0025] The optical component provided in this application includes a first optical element and a second optical element. The second optical element includes a light-transmitting area and a non-light-transmitting area. An optical pattern is provided in the light-transmitting area. Light emitted from the first optical element is projected onto the optical pattern of the second optical element. The optical component has a first light-emitting direction and a second direction perpendicular to the first light-emitting direction. The first optical direction and the light-transmitting area of ​​the second optical element are offset in the second direction, so that in the direction opposite to the first light-emitting direction, the second optical element is blocked by the non-light-transmitting area of ​​the first optical element, thus achieving the concealment of the first optical element. At the same time, when the optical component is viewed from the opposite direction of the first light-emitting direction, only the visual effect of floating illumination at the optical pattern can be observed. Based on the concealed installation of the first optical element and the setting of the optical pattern, a floating light-emitting visual effect is achieved, improving the appearance of automotive lights and allowing for more free and mysterious design.

[0026] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a full understanding of the embodiments disclosed herein. It will then be apparent that one or more embodiments may be practiced without these specific details.

[0027] See Figure 2 The illustration schematically shows an optical component according to an embodiment of this application. This optical component is used in automotive lighting, such as headlights and taillights, and can also be used for interior ambient lighting or interior lighting, etc. The optical component has a first light emission direction. The optical component includes a first optical element 1 and a second optical element 8. The second optical element 8 includes a light-transmitting region 802 and a light-blocking region 801. The light-transmitting region 802 and the light-blocking region 801 of the second optical element 8 can be integrally formed, or they can be formed separately by independent parts; this is not limited here. The second optical element 8 has an optical pattern 803 provided in the light-transmitting region 802.

[0028] Light emitted from the first optical element 1 is projected onto the optical pattern 803 of the second optical element 8, forming a suspended illuminated area in the region where the optical pattern 803 is located. The optical pattern 803 directs the light towards the front of the luminaire at a certain angle. From the observer's perspective, the optical pattern 803 is uniformly illuminated and appears to float on the outer surface. In some specific implementations, the optical pattern 803 can be adjusted in shape (e.g., a fisheye pattern) according to regulatory light distribution requirements to collimate the light from the first optical element 1 and meet regulatory requirements.

[0029] Here, the direction perpendicular to the first light emission direction is defined as the second direction, and the light-transmitting areas 802 of the first optical element 1 and the second optical element 8 are staggered in the second direction so that the first optical element 1 is blocked by the non-light-transmitting area 801 of the second optical element 8 in a direction opposite to the first light emission direction.

[0030] In this embodiment, the first light emission direction is Figure 1 In the X-axis direction, since the non-transparent area 801 of the second optical element 8 needs to block the first optical element 1, and the optical pattern 803 of the transparent area 802 of the second optical element 8 is projected onto it by the light emitted from the first optical element 1, the second direction is... Figure 1 The Z-axis direction in the equation.

[0031] In some optional embodiments, the optical component further includes a light-shielding member 9, which is located between the first optical element 1 and the second optical element 8. The light-shielding member 9 and the non-transparent area 801 of the second optical element 8 form a light-transmitting gap, through which light emitted from the first optical element 1 is projected onto the optical pattern 803 of the second optical element 8.

[0032] The light-shielding member 9 and the non-transparent area 801 of the second optical element 8 are used to block part of the light from the first optical element 1. Due to the blocking by the light-shielding member 9 and the non-transparent area 801 of the second optical element 8, a light-transmitting gap is formed in the light path from the first optical element 1 to the second optical element 8. The light emitted from the first optical element 1 passes through the light-shielding area and illuminates the optical pattern 803, thereby illuminating the optical pattern 803. In a preferred embodiment, the optical pattern 803 deflects the light incident from the incident surface of the second optical element 8, and the light emitted from the emitting surface of the second optical element 8 can be emitted along the first emitting direction, so that the observer can observe the optical pattern 803 being illuminated in a direction opposite to the first emitting direction. At the same time, the light source and the first optical element 8 are blocked, as if the optical pattern 803 is suspended on the surface of the second optical element 8 and illuminated.

[0033] In some alternative embodiments, the second optical element 8 further includes a stepped portion 804, which causes the non-transparent region 801 forming the light-transmitting gap to be offset from the transparent region 802 in the first light-emitting direction. The light-transmitting gap is used to limit the area where the optical pattern 803 of the first optical element 1 is irradiated onto the second optical element 8. Therefore, the light-transmitting gap is located on the light path from the first optical element 1 to the second optical element 8. That is, the final illuminated area (optical pattern 803) of the second optical element 8 and the non-transparent region 801 forming the light-transmitting gap need to be offset on the light path from the first optical element 1 to the second optical element 8, thereby facilitating the limitation of light projection from the first optical element 1 by the light-transmitting gap.

[0034] In this embodiment, the shape of the light-shielding member 9 and the non-transparent area 801 of the second optical element 8 is not limited and need not be restricted to a specific shape. Figures 2-5 The shape of the display can be changed at will according to the actual situation of the vehicle lights, as long as it can block the light emitted by the first optical element 1, forming a light-transmitting gap, so that the light can be projected onto the optical pattern 803 through the light-transmitting gap.

[0035] In some alternative embodiments, the first optical element 1 has a first light-emitting surface 10 (e.g., Figure 6 As shown), on the cross section formed by the first light-emitting direction and the second direction, i.e. Figure 2 The XZ cross-sectional diagram shown shows the endpoint of the first light-emitting surface 10 furthest from the light-transmitting region 802 (in...). Figure 2 The intersection point B of the extension line connecting the upper end of the first light-emitting surface 10 (shown as the upper end point) and the end of the light-transmitting gap formed by the blocking member and the area where the optical pattern 803 is located is the end point of the first light-emitting surface 10 near the light-transmitting area 802 (in Figure 2The intersection point C of the extension line connecting the lower end of the first light-emitting surface 10 (shown as the lower end of the first light-emitting surface 10) and the end of the non-transparent region 801 that forms the light-transmitting gap with the region where the optical pattern 803 is located is the region where the optical pattern 803 is located, near the end of the first optical element 1 (in the...). Figure 2 The upper endpoint of the optical pattern 803 is shown as G, and the region where the optical pattern 803 is located is far from the endpoint of the first optical element 1 (in...). Figure 2 The lower endpoint of optical pattern 803 (shown in the image) is H. The height difference between endpoint H and intersection B in the second direction is greater than or equal to 0.5 mm; and the height difference between intersection C and endpoint G in the second direction is greater than or equal to 0.5 mm. In other words, in the XZ coordinate system, the coordinates of intersection B are (X2, Z2), the coordinates of intersection C are (X3, Z3), the coordinates of endpoint G are (Xa, Za), and the coordinates of endpoint H are (Xb, Zb), where Zb - Z2 ≥ 0.5 mm, and Z3 - Za ≥ 0.5 mm. Therefore, it can be ensured that the optical pattern 803 is fully illuminated by the first optical element 1.

[0036] Considering that in some optional embodiments, the endpoints of the base surface 805 where the optical pattern 803 is located (i.e. Figure 2 The base surface 805 containing the optical pattern 803 may have rounded corners at the endpoint D near the first optical element 1 and the endpoint A away from the first optical element 1. This is to prevent light from illuminating the rounded corners, which could lead to defects or bright lines in the optical guide ruler. Therefore, in some optional embodiments, the illuminated area is located within the base surface 805. In the cross-section formed by the first light-emitting direction and the second direction, the endpoint A of the base surface 805 near the first optical element 1 is designated as the base surface 805, and the endpoint D is designated as the base surface 805 away from the first optical element 1. The height difference between endpoint A and the intersection point C in the second direction is greater than or equal to 2 mm; and the height difference between the intersection point B and endpoint D in the second direction is also greater than or equal to 2 mm. In other words, in the XZ coordinate system, the coordinates of endpoint A are (X4, Z4), and the coordinates of endpoint D are (X1, Z1), satisfying Z4-Z3≥2mm and Z2-Z1≥2mm. This avoids the aforementioned defects or bright lines in the optical guide ruler and also ensures the feasibility of the manufacturing process for the second optical element 8.

[0037] In some optional embodiments, considering that the second optical element 8 can both block the first optical element 1 and allow the light emitted from the first optical element 1 to be projected onto the optical pattern 803, so as to achieve the effect of forming a suspended point lighting in the area where the optical pattern 803 is located, the projection point E of the end of the first light-emitting surface 10 near the light-transmitting area 802 in the first light-emitting direction, and the height difference between the projection point and the end of the non-light-transmitting area 801 that forms a light-transmitting gap is greater than or equal to 10mm.

[0038] In some alternative implementations, such asFigure 2 As shown, the second optical element 8 is recessed near the surface of the first optical element 1 to form an optical pattern 803. Or as... Figure 5 As shown, the second optical element 8 protrudes outward from the surface of the first optical element 1 to form an optical pattern 803.

[0039] When the second optical element 8 needs to be recessed close to the surface of the first optical element 1 to form an optical pattern 803, it is preferable to use CNC machining process to manufacture the second optical element 8.

[0040] The second optical element 8 needs to protrude from the surface of the first optical element 1 to form an optical pattern 803. Preferably, the second optical element 8 is manufactured using a mold injection molding process.

[0041] In some alternative implementations, such as Figure 2 and Figure 5 The first optical element 1 is a light guide. The light guide needs to be installed inside the automotive lamp and can be installed using the mounting part 7. The optical assembly also includes a light source 11, which is located at the end of the light guide. The so-called light guide component refers to a light guide component that mainly transmits light within it by total internal reflection. Because it mainly uses total internal reflection for transmission, the light guide component has high optical efficiency and low light loss.

[0042] Furthermore, such as Figure 6 As shown, the light guide has light guide teeth 2 extending along the light guide axis. The light guide teeth 2 are located on the side closer to the mounting portion 7. After the light emitted from the light source 11 enters the light guide, it illuminates the light guide teeth 2, and after being reflected by the light guide teeth 2, it is emitted from the first light-emitting surface 10 of the light guide. The first light-emitting surface 10 is located on the side away from the mounting portion 7. The line connecting the light guide teeth 2 and the light guide axis forms an angle greater than 0 degrees with the first light-emitting direction. Therefore, the light emitted from the first optical element 1 can illuminate the light transmission gap, thereby improving the lighting efficiency. In other words, in such a way... Figure 2 On the cross-section shown, the center of the optical guide tooth 2, the center of the light transmission gap, and the center of the optical pattern 803 are roughly on a straight line.

[0043] In other embodiments, the first optical element 1 may be as follows: Figure 3 The thick wall shown has a light source 11 located at one end (a collimation structure can be provided at the end). The light source 11 enters the thick wall through the end. Based on the law of refraction of light, the light emitted by the light source 11 propagates through the optical collimation structure at the light-inlet end of the thick wall and forms a uniform light emission effect on the other end face. It then exits from the other end face to illuminate the optical pattern 803.

[0044] The first optical element 1 can also be, for example, Figure 4The reflector shown can change the propagation direction of the light source 11 based on the law of reflection of light, so that the reflected light can illuminate the optical pattern 803.

[0045] According to another aspect of this application, an automotive lighting fixture is also provided, including the optical components of any of the foregoing embodiments, to have the same technical effects as the optical components.

[0046] According to another aspect of this application, a vehicle is also provided, including automotive lamps of any of the foregoing embodiments, to have the same technical effects as automotive lamps.

[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
