Description

Optical structure, car light module, car light and vehicle

Technical Field

Background

With the development of economic society, automobiles as transportation means indispensable in daily production and life play an increasingly important role in human society. However, as automobiles become more popular, accidents inevitably occur more and more, and the night is a high-incidence time period of accidents. The high beam of the vehicle is to provide more visual field space for the driver on the road with poor light and few vehicles, and the visual field in front of the vehicle is reduced when some drivers often switch the high beam or the low beam in time when meeting or following the vehicle, and the sudden change of the visual field easily causes traffic accidents. The adaptive high beam system (ADB) can adjust the illumination condition of the corresponding area according to the position and the distance of the front vehicle, thereby avoiding the dazzling of the high beam function to the front vehicle or the opposite vehicle and avoiding the potential safety hazard caused by the sudden change of the visual field due to the complete closing of the high beam.

With the pursuit of host computer factories for automobile modeling, the light-emitting window of the automobile lamp is more and more flattened, which requires that the upper and lower openings of the lens used by the module are very small, and the traditional high beam ADB design method is limited by the lens opening, so that the design of the small opening of the automobile lamp is difficult to realize, and the modeling effect of the light guide type (narrow and long lens) cannot be realized.

Recently, a light incident surface is formed by combining a plurality of curved surfaces arranged left and right, and a light emergent surface is a lens with a smooth curved surface to form a flattened light emergent opening of the car lamp. Each curved surface of the lens light incident surface forms a focus of the lens, corresponds to a light source and forms a pixel of the ADB vehicle lamp. Due to the limitation of the left and right width of the vehicle lamp, the curved surface which can be arranged on the light incident surface of the lens is limited, so that the number of pixels of the ADB vehicle lamp is limited. Increasing the left and right size of the lens to increase the number of pixels also presents a greater challenge to the design of the vehicle lamp dimming structure.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

It should be noted that, in the following description, for example, "up", "down", "left", "right", "front", "back", and the like, refer to the normal directions of the vehicle when the vehicle lamp module is applied to the vehicle, and the directions of the vehicle head and the vehicle tail are front, and the directions of the driver seat and the front passenger seat are left, the directions of the vehicle roof and the wheels are down, respectively, according to the driving habit in China. The "light emitting direction" is the irradiation direction of the light emitting from the automotive headlight system, and can be set according to the illumination function of the car light to be realized, for example, the light emitting direction of the headlight is directed to the front of the vehicle, and the light emitting direction of the corner light is directed to the outside of the vehicle. This is done solely for the purpose of facilitating the description of the invention and simplifying the description, and is not intended to indicate or imply that the device or element so referred to must be in a particular orientation, constructed and operated, and therefore should not be taken as limiting the invention.

As shown in fig. 1 to 8, the optical structure of the present invention includes a primary optical unit, a reflective plate 4 with a light exit hole 41, and a secondary optical unit 8, which are sequentially arranged along a light exit direction, the primary optical unit includes a main primary optical unit 2 and at least one sub primary optical unit 6, the main primary optical unit 2 includes a main light condensing portion 21, a main light passing portion 22, and a main light exit portion 23, the sub primary optical unit 6 includes a sub light condensing portion 61, a sub light passing portion 62, and a sub light exit portion 63, an exit light of the main light exit portion 23 can be emitted to the secondary optical unit 8 through the light exit hole 41 and then emitted from the secondary optical unit 8, and an exit light of the sub light exit portion 63 can be reflected to the secondary optical unit 8 by the reflective plate 4 and then emitted from the secondary optical unit 8. Under normal conditions, the left and right width of the vehicle is constant, so that the left and right width of the vehicle lamp is relatively fixed and limited, the positions of the main primary optical unit 2 and the auxiliary primary optical unit 6 are different, for example, the main primary optical unit 2 can be located behind the reflector 4 as the primary optical unit in the prior art, the same number of pixels as that in the prior art can be formed, the auxiliary primary optical unit 6 can be located above or below the reflector 4, and also can form a certain number of pixels, and the emergent light rays of the primary optical units at different positions are all emergent from the secondary optical unit 8, so that the number of pixels of the ADB high beam module can be increased on the premise that the left and right dimensions of the vehicle lamp are not changed, the resolution of the ADB high beam is higher, the road illumination effect of the vehicle lamp is further improved, and the safety performance is improved; and if the pixel quantity of ADB high beam module keeps unchangeable, then can reduce the left and right sides size of module, greatly reduced car light structure's that adjusts luminance the design degree of difficulty.

The number of the secondary primary optical units 6 may be 1 or more, and each secondary primary optical unit 6 may be perpendicular to the primary optical unit 2 as shown in fig. 1 to 8, or may be inclined to the primary optical unit 2, so that the emergent light of each primary optical unit 2 is emitted from the secondary optical unit 8 by using the reflection plate 4 with different angles. The up-down position of the ADB pixel (pixel formed by the light reflected by the reflection plate 4) can be further adjusted by adjusting the angle of the reflection plate 4.

The diameter of the light exit hole 41 is 0.1-1mm, preferably less than 0.5mm, and the size of the light exit hole 41 can be adjusted according to the light convergence effect, and the light exiting from the main light exit part 3 is not blocked in principle.

As shown in fig. 1, the distance between the secondary primary optical unit 6 and the reflective plate 4 can be adjusted to focus the outgoing light of the secondary light-emitting portion 63 on or near the reflective plate 4, and the left, right, up and down positions of the secondary light-emitting portion 63 can be controlled to make the focusing point of the outgoing light of the secondary light-emitting portion 63 avoid the light-emitting hole 41; as shown in fig. 2, the light emitted from the sub light-emitting portion 63 may be divergently irradiated onto the reflector 4, reflected by the reflector 4, and focused. When the light is diverged, only a very small amount of light will exit from the light exit hole 41 because the light is more diverged on the reflector 4, and most of the light will be reflected and focused. In this way, the secondary primary optical unit 6 and the secondary optical unit 8 are in an out-of-focus state, and the finally formed ADB pixel is relatively large and is suitable for being used as pixels on both sides of the ADB high beam shape, because the ideal ADB high beam shape satisfies the requirements of narrow width of the middle pixel (high resolution), wide width of the pixels on both sides (low resolution), and better uniformity of the beam shape with the wide width of the pixels on both sides of the beam shape than the narrow width of the pixels on the inner side of the beam shape. After the ADB pixels formed correspondingly to the main primary optical unit 2 are superposed, the uniformity of the whole light shape is improved.

The reflecting plate 4 may be a flat reflecting plate, an ellipsoidal reflecting plate, a parabolic reflecting plate, a concave reflecting plate, or the like, as necessary.

In general, the main light collecting unit 21 includes a plurality of light collecting structures, and the light collecting structure may have a cup shape or other structures having a light collecting function. In order to achieve a good light-emitting effect, convex surfaces corresponding to the light-condensing structures one to one are formed on the main light-emitting portion 23, and the convex surfaces may be convex cylindrical surfaces or free curved surfaces protruding forward, and it is preferable to use convex cylindrical surfaces extending in the vertical direction. The light is converged and collimated by the light-converging structure and then transmitted to the corresponding convex surface by the main light-passing part 22, and the light is converged by the convex surface.

In a preferred embodiment of the present invention, the light exit holes 41 are formed in the reflection plate 4 in one-to-one correspondence with the convex surfaces. The light converged by the convex surface passes through the corresponding light exit hole 41 to be emitted to the secondary optical element 8, and is converged by the secondary optical element 8 to be emitted.

As an embodiment of the secondary optical unit 8 of the present invention, it includes a plurality of light incident surfaces 81 and a light emitting surface 82, and the plurality of light incident surfaces 81 are formed as curved surfaces that correspond to the light emitting holes 41 one to one and are convex toward the light emitting holes 41. The light emitting surface 82 is a smooth curved surface formed by sweeping a vertical bus along a set curve, the set curve is a curve protruding towards the light emitting direction, the vertical bus is a longitudinal sectional line of the light emitting surface 82, and the shape of the light emitting surface 82 and the shape of the set curve can be formed according to the modeling requirement of the vehicle lamp. Each light incident surface 81 and the light exiting surface 82 form a converging structure with a convex lens-like function having a focus, and each converging structure can form the refraction effect of a conventional convex lens to project light incident on the secondary optical unit 8 to form an illumination spot. The plurality of illumination light spots are mutually connected and overlapped to form an illumination light shape.

In order to enable the optical structure of the present invention to realize multiple functions, a light adjusting component 9 may be further disposed between the reflection plate 4 and the secondary optical unit 8, the light adjusting component 9 has a rotation shaft 91, a light shielding plate 92 and/or a transparent plate 93 are fixedly connected to two sides of the rotation shaft 91, and the rotation shaft 91 can drive the light shielding plate 92 and/or the transparent plate 93 to rotate. Different rotation angles of the rotating shaft 91 can enable the light shielding plate 92 or the light transmitting plate 93 to be located on the light path between the reflecting plate 4 and the secondary optical unit 8, or enable neither the light shielding plate 92 nor the light transmitting plate 93 to be located on the light path between the reflecting plate 4 and the secondary optical unit 8, so that a corresponding signal lamp function or a near-far light illumination function is achieved.

The light shielding plate 92 is made of a light shielding material and can shield light passing therethrough. The edge of the light shielding plate 92 may also be formed with a low-beam cut-off line structure, when the light shielding plate 92 is located on the light path between the reflection plate 4 and the secondary optical unit 8, a part of light can be shielded, and the other part of light is emitted from one side of the edge of the light shielding plate 92 with the low-beam cut-off line structure, so as to form a low-beam light shape with a low-beam cut-off line.

The light-transmitting plate 93 is made of a light-scattering material, and can be made of a PC-based light-scattering material or a PMMA-based light-scattering material. The transparent plate 93 can scatter the passing light, and improve the uniformity of the emergent light.

When neither the light-shielding plate 92 nor the light-transmitting plate 93 is on the optical path between the reflecting plate 4 and the secondary optical unit 8, all the light from the reflecting plate 4 is irradiated to the secondary optical unit 8, and is projected by the secondary optical unit 8 to form a high beam shape.

According to the grading requirement (including illumination intensity requirement and light chromaticity requirement etc.) of different signal lamps, light-passing board 93 can select different shapes, different colours and the material of different materials to make to realize different functions, for example:

(1) the light transmitting plate 93 may be made of a transparent light scattering material, and may scatter light and transmit white light, thereby forming a daytime running light function according with the daytime running light regulations. When the light-transmitting plate 93 is vertically placed, the light transmits white light through the light-transmitting plate 93, so that the function of a daytime running lamp is realized;

(2) the light-transmitting plate 93 may be made of a colored light-scattering material, and can scatter and filter the passing light to form a signal light function with a set color.

(3) The light-transmitting plate 93 may be provided with several pieces, which light-transmitting plates 93 are made of different light-scattering materials, to realize three signal lamp functions of a daytime running lamp, a position lamp and/or a turn lamp.

The dimming means 9 preferably comprises two or three light-shielding plates 92 and/or light-transmitting plates 93. When two light-transmitting plates 93 are adopted, the daytime running lamp and the position lamp can share one light-transmitting plate 93 because the requirements of the illumination intensity are different, the functions of the two signal lamps are realized by adjusting the luminous flux of the light source, and the requirement of the light chromaticity of the steering lamp is different from the requirement of the light chromaticity of the other two signal lamps, so that the light-transmitting plate 93 made of different materials is required to be independently adopted for realization.

The above-described several means of the light shielding plate 92 and the light transmitting plate 93 may be used alone or in combination. For example, the light shielding plate 92 and the light transmitting plate 93 of the mode (1) may be used in combination to realize the functions of the high beam, the low beam, and the daytime running light, and the light shielding plate 92 and the light transmitting plate 93 of the mode (3) may be used in combination to realize the functions of the high beam, the low beam, the daytime running light, the position light, and the turn light. In this case, the optical structure of the present invention may be divided into two parts, i.e., a left part and a right part, one part being used to implement the high beam function and the low beam function, and the other part being used to implement the turn signal lamp and/or the position lamp function by light distribution.

Several light shielding plates 92 can be connected to the light adjusting component 9, and the edges of different light shielding plates 92 can be provided with low-beam cut-off line structures of different shapes, so that the formed low-beam light shape meets the requirements of different countries on low-beam modes.
