Cross Reference to Related Applications

This application claims the benefit of chinese patent application 201920726090.0 filed on 20/05/2019, the contents of which are incorporated herein by reference.

Technical Field

The invention relates to an automobile lamp, in particular to a matrix type automobile lamp optical device. In addition, the invention also relates to a vehicle lamp and a vehicle comprising the matrix type vehicle lamp optical device.

Background

In order to improve the night Driving safety, a matrix type lamp having an ADB (Adaptive Driving Beam) function is becoming the mainstream of the automobile configuration, and is becoming more and more popular from a high-end vehicle to a medium-class vehicle. Generally, the ADB means a high beam having at least two pixelations, which can shield an object, prevent dazzling of other users on a road, and improve driving safety.

In addition, no matter new energy vehicles or fuel vehicles are adopted in the future, energy conservation and emission reduction become a technology development direction which is not changed for a long time in the field of automobiles. The car light is used as a necessary part of the car, the power of the car light can be effectively reduced by improving the optical efficiency of the car light, and the high luminous efficiency becomes a necessary choice for the industry development, thereby being beneficial to saving energy.

Furthermore, the appearance of the car is a major factor that the customer chooses to purchase. The novel and unique car lamp which gets rid of the traditional shape can lead consumers to be on the spot and becomes an important selling point of the car. At present, the automobile lamp tends to be miniaturized and flattened.

At present, the lighting module for realizing the matrix car lamp mainly has two types, namely a reflection type and a projection type. The reflective lighting module is formed by arranging and combining a plurality of reflective bowls to form light spots in different areas; projection-type lighting modules generally have an imaging lens in the form of a convex lens pattern, with the matrix-arranged light guide posts forming the matrix-arranged light pattern. The reflective lighting module has the following disadvantages: the reflecting bowl needs a large opening, a plurality of pixels occupy a space in the lamp when being arranged, and meanwhile, the solid angle of the reflecting bowl is not large and the lighting effect is not high; the projection type lighting module is generally provided with two stages of optical parts, wherein the mature scheme of the first stage of optical part is optical silica gel material, the forming difficulty is high, the assembly is difficult, and the whole system is complex and the installation and production cost is high due to the addition of the second stage of optical part; in addition, the projection type lighting module is a lens in appearance, and has no great difference with a common projection type low beam or high beam, which is easy to cause aesthetic fatigue. The light efficiency is not high due to the loss of the two-stage optical element.

In view of this, the optical device of the matrix vehicle lamp in the prior art has low optical efficiency and a relatively complex structure.

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, and it is to be understood that the detailed description is provided for purposes of illustration and explanation and is not intended to limit the scope of the invention.

It should be noted that, in the following description, for clearly explaining the technical solution of the present invention, directional terms, such as "rear" and "front", are used according to the meaning of the directional terms referred to by the light emitting direction, for example, taking a single light collector 101 as an example, one end of the light collector 101 where the light emitting surface is located is a front end, and vice versa is a rear end, and from the rear to the front, the left and right of the light collector 101 are left and right directions.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a removable connection, or an integral connection; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 4 and 28 to 30, the matrix vehicular lamp optical device of the present invention includes a plurality of light collectors 101 adapted to be freely arranged; an LED light source 7 is arranged at the focus of each condenser 101, and each LED light source 7 is suitable for being independently lightened to form multi-pixel self-adaptive high beam through direct projection of the condenser 101.

It should be noted here that the condenser 101 of the present invention is in a condensing cup shape, the LED light sources 7 are arranged in one-to-one correspondence with the condenser 101, the light emitting centers of the LED light sources 7 coincide with the focal point of the condenser 101, each LED light source 7 is configured to be capable of independently turning on and off, so that a multi-pixel adaptive high beam can be formed by direct projection of the condenser 101, and the light emitting area of the LED light source 7 is preferably 0.5mm²Or smaller.

As shown in fig. 1 and 2, in the first embodiment of the present invention, the matrix vehicular lamp optical device includes two rows of transversely arranged optical collector groups 1, each row of optical collector groups 1 includes 5

optical collectors

101, and 10 optical collectors 101 are integrally formed. The light emitting surfaces of the two rows of optical concentrators 101 located in the middle of the optical concentrator groups 1 are formed as light emitting surfaces 102a, the light emitting surfaces 102a are planes perpendicular to the optical axis 6 of the optical concentrator located in the middle, and the light emitted from the light emitting surfaces 102a correspondingly forms a high beam central area light type as shown in fig. 7. In order to improve the optical efficiency of the light collectors 101, the optical axis 6 of each light collector coincides with the optical axis of the LED light source 7, but if the

light emitting surfaces

102b, 102c, 102d, 102e, 102f, 102g, 102h and 102i are all planes perpendicular to the optical axis 6 of the light collector located at the middle position like the light emitting surface 102a, the matrix-type vehicular lamp optical device cannot realize multi-pixel adaptive high-beam illumination with multiple pixels connected to each other, so the

light emitting surfaces

102b, 102c, 102d, 102e, 102f, 102g, 102h and 102i are inclined to different degrees with respect to the light emitting surface 102a, that is, an included angle is formed between the light emitting surfaces of the light collectors 101 located at both sides and the light emitting surface of the light collector 101 located at the middle position, and light spots formed by projecting the light emitting surfaces located at both sides of the light emitting surface 102a are sequentially as shown in fig. 8, fig. 9, fig 10, fig 11, fig. and, Fig. 12, 13, 14 and 15. If all the LED light sources 7 corresponding to all the optical concentrators 101 are turned on, a high beam light type as shown in fig. 16 can be formed, and light spots with different widths can be obtained by adjusting the light emitting surface of each optical concentrator 101, so as to realize multi-pixel adaptive high beam with high middle resolution and low resolution on both sides. On the other hand, if the LED light sources 7 corresponding to the

light emitting surfaces

102a, 102b, and 102c are turned off, a high beam pattern having a dark area is formed as shown in fig. 17.

Further, because the plurality of light collectors 101 are integrally formed, light leakage occurs between the light collectors 101, and a part of light of the light collectors 101 is emitted to the light-emitting surface of the light collector 101 adjacent to the light collectors 101, and is emitted from the light-emitting surface to form stray light, in order to avoid the occurrence of the stray light, as shown in fig. 22, except for the light collector 101 located at the middle position, the light-emitting surfaces of the other light collectors 101 are inclined towards the light-emitting surface of the light collector 101 located at the middle position, and the inclination angle satisfies that the light refracted from the light collector 101 adjacent to the light collector 101 to the light-emitting surface of the light collector 101 can be totally reflected, at this time, the transverse sectional lines of the light-emitting surface of each light collector 101 can be spliced into a concave curve which is concave backwards, so that the stray light can be prevented from being formed after the light-emitting surface exits from. Meanwhile, in order to satisfy the critical condition of total reflection of light (the incident angle is larger than the critical angle), the ratio of the length of the condenser 101 from the rear to the front in the optical axis direction to the width in the left-right direction is small, so that the length of the condenser 101 in the front-rear direction can be made short.

As shown in fig. 28, in the second embodiment of the present invention, the matrix vehicular lamp optical device includes 11 vertically arranged

light collectors

101, and 11 light collectors 101 are integrally formed into one light collector group 1. As shown in FIG. 28, an LED light source (not shown) with a small light-emitting area is disposed at the focal point of each condenser 101, and the light-emitting area of the LED light source is 0.1mm²～1mm ². In order to better arrange and combine the condensers 101, the light-emitting surface of each condenser 101 is cut into a rectangle, so that the light form formed by the direct projection of the light emitted by the LED light sources through the condenser 101 is a light spot similar to a rectangle, as shown in fig. 31, the light spot formed by the direct projection of the light emitted by a single LED light source through the condenser 101 is a light spot, the widths of the left side and the right side are about 5 °, and the left and the right directions of the pixel center position are both 0 °, which is the origin of a two-dimensional coordinate system. The 11 concentrators 101 may be integrally formed to reduce fitting errors. Corresponding 11 LED light sources can be arranged on a circuit board to reduce the circuit volume. Since the LED light source does not include a complicated optical system such as a reflector and a lens, the light emitted from the LED light source is directly projected by the condenser 101 to realize illumination, thereby reducing light loss due to multi-stage refraction and improving optical efficiency. The LED light source can be a single-pixel LED light source or a multi-luminous-area LED light source, so that the requirement of illumination intensity of different illumination areas in a Matrix light type is met.

As shown in fig. 25 to 27, the direction of the optical axis 6 of the condenser is defined as the Z axis, the left-right direction is defined as the X axis, and the up-down direction is defined as the Y axis. On the basis of the above-described embodiment, as shown in fig. 29, 11 condensers 101 vertically arranged from top to bottom are rotated about their own Y axes by-5 °/-4 °/-3 °/-2 °/-1 °/0 °/1 °/2 °/3 °/4 °/5 °, i.e., the condenser 101 located at the intermediate position is not moved or rotated by 0 °, among two condensers 101 respectively adjacent to both sides of the condenser 101 located at the intermediate position, the optical axis of one condenser is horizontally rotated counterclockwise by 1 °, by-1 ° in vector representation, the optical axis of the other condenser is horizontally rotated clockwise by 1 °, by +1 ° in vector representation, and so on, among the other 4 condensers 101 located on the condenser 101 side at the intermediate position, by-2 °, respectively, from near to far, in the distance from the condenser 101 located at the intermediate position, -3 °, -4 °, and-5 °, and +2 °, +3 °, +4 °, and +5 ° are rotated from near to far, respectively, in the other 4 concentrators 101 on the other side of the concentrator 101 in the intermediate position. Alternatively, the rotation directions of the condensers 101 located on both sides of the condenser 101 at the intermediate position are switched at once, and the same technical effect is obtained. Therefore, the included angle of the optical axes of the adjacent condensers is 1 degree; correspondingly, the central positions (left and right) of the 11 LED light sources emitting pixels in the 11 condensers 101 are respectively: -5 °/-4 °/-3 °/-2 °/-1 °/0 °/1 °/2 °/3 °/4 °/5 °; the 11 pixels are mutually overlapped, so that the connection uniformity of the pixels is ensured; the pixels are staggered by 1 degree, and the pixels can independently illuminate an area; the 11 pixels are superimposed to form an overall light pattern, as shown in FIG. 32. When the vehicle-mounted camera is used specifically, when a vehicle or a pedestrian driving/walking on the head is sensed by the vehicle-mounted camera, pixels formed by a plurality of LED light sources in the middle can be automatically extinguished, so that the ADB shielding function of the middle area is realized, as shown in FIG. 33. Condenser 101 can form different position facula according to the rotation of different angles, through the angle design of single lighting unit, realize ADB illumination function in a flexible way, a plurality of collimation units based on condenser 101 stagger in order to shine different regions with certain angle each other, the bright of realizing different regions through the bright of going out of LED light source is lighted, cooperation vehicle-mounted camera realizes the ADB function, the volume is littleer, the structure is compacter, simple, can realize more nimble ADB function in limited car light space.

Of course, the matrix vehicular lamp optical device of the present invention may also include 11 transverse light collectors 101 arranged in series, and the operation principle thereof is the same as that of the embodiment shown in fig. 28, and will not be described herein again.

As shown in fig. 30, in the third embodiment of the present invention, the matrix vehicular lamp optical device includes 12 light collectors 101, which are divided into 4 light collector groups 1, and each group of 3 light collectors 101 is vertically and continuously arranged to form one light collector group 1. The two concentrators 101 marked in fig. 30 are concentrators 101 located at the middle positions, wherein 5 concentrators 101 located at the upper side of the concentrator 101 located above are respectively rotated by-1 °, -2 °, -3 °, -4 °, and-5 ° from the near to the far from the

concentrator

101, and 5 concentrators 101 located at the lower side of the concentrator 101 located below are respectively rotated by +1 °, +2 °, +3 °, +4 °, and +5 ° from the near to the far from the concentrator 101. Alternatively, the rotation directions of the condensers 101 on both sides of the two condensers 101 located at the intermediate position are switched at once, and the same technical effect is obtained.

When the automobile light collector is used specifically, the arrangement form of the light collectors 101 can be flexibly arranged according to the increasingly compact automobile light model, and the number of the light collectors 101 can be customized and can be more or less; the arrangement can also be horizontal, vertical, oblique and the like; the optical fiber can be arranged continuously or in sections, for example, 3 optical collectors 101 are used as an

optical collector group

1, and 6 groups are arranged; or 5 in one group, 4 in groups, and the like.

As a preferred embodiment, as shown in fig. 1 and 2, and fig. 28 and 29, each of the concentrators 101 is integrally formed into at least one row of concentrator groups 1, and a single row of the concentrator groups 1 has the concentrators 101 arranged in series, horizontally or vertically or obliquely.

In another preferred embodiment, the optical axis 6 of each condenser coincides with the optical axis of the corresponding LED light source 7, and the optical axes 6 of the plurality of condensers located on both sides of the condenser 101 at the intermediate position are parallel to the optical axis 6 of the condenser at the intermediate position.

Here, when the number of the condensers 101 in a single condenser group 1 is an odd number, the condenser located at the middle position refers to one condenser located at the middle position; whereas when the number of concentrators 101 within a single concentrator group 1 is even, the concentrator in the middle position is two concentrators 101 in the middle position.

In order to improve the optical efficiency of the condenser 101, the optical axis 6 of each condenser coincides with the optical axis of the LED light source 7, so that the light emitted by the LED light source 7 can enter the condenser 101, and the multi-pixel adaptive high beam can be formed while the light utilization rate is improved.

It should be explained here that the optical axis 6 of the condenser refers to the axis along the direction of transmission of the light rays and passing through the focal point of the condenser 101; the optical axis of the LED light source 7 refers to an axis along the central ray propagation direction and passing through the light emission center of the LED light source 7.

As an alternative to the above preferred embodiment, the optical axes 6 of the plurality of optical collectors located on the first side of the optical collector 101 at the intermediate position are horizontally rotated clockwise by different angles, respectively, so that the farther away from the optical collector 101 at the intermediate position, the optical axis 6 of the optical collector in the plurality of optical collectors 101 is from the optical axis 6 of the optical collector at the intermediate position, the larger the included angle is; the plurality of optical collectors 101 located on the second side of the optical collector 101 at the middle position are horizontally rotated by different angles counterclockwise respectively, so that the farther from the optical collector 101 at the middle position, the included angle between the optical axis 6 of the optical collector and the optical axis 6 of the optical collector at the middle position in the plurality of optical collectors 101 is larger.

Similarly, for the light emitting type, the optical axes 6 of the condensers at the two sides may form a certain included angle with respect to the optical axis 6 of the condenser at the middle position, while the optical axis 6 of the condenser at the middle position is overlapped with the optical axis of the LED light source 7, and the condensers 101 at the two sides are staggered at a certain angle, so that different areas can be irradiated, and the lighting of different areas can be realized by the on-off of the LED light source 7.

More preferably, the angle between the optical axes 6 of two adjacent concentrators is 1 °.

Further preferably, the light emitting surfaces of all the optical concentrators 101 located at the middle position form a plane, and are perpendicular to the optical axis 6 of the optical concentrator located at the middle position, and an included angle is formed between the light emitting surfaces of the optical concentrators 101 located at the two sides of the optical concentrator 101 located at the middle position and the light emitting surface of the optical concentrator 101 located at the middle position.

It can be seen that, no matter how many rows of optical concentrator groups 1 are formed, the light-emitting surfaces of the optical concentrators 101 located at the middle position form a vertical plane perpendicular to the optical axis 6 of the optical concentrators, and the light-emitting surfaces at the two sides are inclined to the vertical plane to different degrees, that is, an included angle is formed between the light-emitting surfaces at the two sides and the light-emitting surface located at the middle position, so that light spots projected and formed by the optical concentrators 101 are staggered, and a multi-pixel high beam type with multiple pixels connected with each other can be formed.

Still preferably, in order to prevent the light rays refracted by each condenser 101 to the light-emitting surface of the adjacent condenser 101 from being emitted from the light-emitting surface of the adjacent condenser 101 to form stray light, the light-emitting surfaces of the condensers 101 at two sides of the condenser 101 located at the middle position are adapted to totally reflect the light rays emitted from the adjacent condenser 101, and the transverse sectional lines of the light-emitting surfaces of the condensers 101 are adapted to be spliced into a concave curve which is concave backwards.

As shown in fig. 5 and 6, transverse sectional lines of the light emitting surfaces of all the light collectors 101 are spliced together to form an inward concave curve. Here, the transverse sectional line refers to an intersection line of a virtual plane and a light exit surface after virtually cutting the condenser group 1 through the virtual plane extending in the left-right direction parallel to the optical axis of the condenser 101.

As shown in fig. 30, each of the optical concentrators 101 is divided into a plurality of optical concentrator groups 1, each of the optical concentrator groups 1 has a plurality of optical concentrators 101 arranged in series in a horizontal direction, a vertical direction, or an oblique direction, and each of the optical concentrator groups 1 is arranged at intervals in the horizontal direction, the vertical direction, or the oblique direction.

As a further preferred embodiment, the optical axes 6 of two concentrators 101 located at the middle position are parallel, and the optical axes 6 of a plurality of concentrators adjacent to one concentrator 101 side of one concentrator 101 of the two concentrators 101 located at the middle position are horizontally rotated clockwise by different angles, so that the farther from the concentrator 101 located at the middle position, the included angle between the optical axis 6 of the concentrator and the optical axis 6 of the concentrator located at the middle position is increased; the plurality of concentrators 101 adjacent to the side of the other concentrator 101 of the two concentrators 101 located at the intermediate position are horizontally rotated counterclockwise by different angles, respectively, so that the farther the concentrator 101 located at the intermediate position is from the optical axis 6 of the concentrator, the larger the angle between the optical axis 6 of the concentrator and the optical axis 6 of the concentrator located at the intermediate position is.

More preferably, the optical axes 6 of two adjacent concentrators, except for the two said concentrators 101 in the intermediate position, are at an angle of 1 °.

Here, as shown in fig. 30, in the plurality of condenser groups 1 of the independent structure, the number of the condensers 101 in each row of the condenser groups 1 is an odd number equal to the number of the condenser groups 1, and the number of the condenser groups 1 is an even number, so that the condenser in the middle position is two condensers 101 indicated in fig. 30, the optical axes 6 of the two condensers are parallel, the condensers 101 in both sides are horizontally rotated by different angles with respect to the optical axes 6 of the two condensers in the middle position, and the farther away from the condenser 101 in the middle position, the larger the angle of rotation is.

Further, the light exit surface of each condenser 101 is rectangular, each LED light source 7 is a single-chip LED light source, and light spots formed by direct projection of light emitted by each LED light source 7 through the corresponding condenser 101 are rectangular light spots.

As a specific structure form, the outer side surfaces of the outermost concentrators 101 on the left and right sides are gradually close to the optical axis 6 direction of the concentrator at the middle position from the back to the front along the light propagation direction.

With reference to fig. 5, 6, 21 and 22, the outer side surfaces of the light collectors 101 located at the outermost sides of the left and right sides of the light collector group 1 gradually approach the optical axis 6 from back to front, so that the light projected on the outer side surfaces by the LED light sources 7 can be refracted out from the outer side surfaces, instead of being totally reflected to the light exit surface of the light collectors 101 by the outer side surfaces and emitted out from the light exit surface to form stray light.

As another specific structure form, the light shielding members 2 are arranged around the condenser group 1.

As shown in fig. 18 to 22, the light-emitting surfaces of the light collectors 101 at two sides of the light collector 101 at the middle position are formed as total reflection surfaces, and part of the light is totally reflected by the total reflection surfaces and then emitted from the side surfaces of the light collector group 1 to form part of stray light; in addition, stray light is also generated from light obliquely emitted from the outer surface of the condenser group 1. In order to eliminate stray light, the light-shielding member 2 may be disposed around the optical collector group 1, the light-shielding member 2 may be a light-shielding cover formed of a black light-shielding material, or may be a light-shielding cover coated with a matte black paint or other light-shielding materials, or may be a light-shielding layer directly disposed around the optical collector group 1, the light-shielding layer may be a matte black paint or a dermatoglyph structure, and a dark color coating is coated on a surface of the dermatoglyph structure, the dark color coating may be a bright black paint or other dark color bright paints, or may be other light-shielding structures other than the above structures, and the purpose of the light-shielding member is to shield stray light emitted from a side surface of the optical collector group 1.

As shown in fig. 23 and 24, as another specific structure form, the solar concentrator further includes a circuit board 3 and a heat sink 4, a positioning pin 5 is disposed on the heat sink 4, the positioning pin 5 is adapted to sequentially penetrate through the circuit board 3, the light collector group 1 and the light shielding member 2, and the positioning pins 5 are used to simultaneously position a plurality of components, so that the solar concentrator is simple in structure and good in positioning effect among the components.

Further, the width of the transverse section of the condenser 101 at the middle position is greater than the widths of the condensers 101 at two sides of the same transverse section, so that the central condenser 101 is greater than the condensers 101 at two sides in appearance, which can meet the requirement of high illuminance in the central area of high beam and improve the utilization rate of light.

In addition, the ratio of the length of each condenser 101 from back to front to the width of each condenser 101 in the left-right direction along the light propagation direction is small, so that the length of each condenser 101 from front to back is relatively short compared with the width of each condenser 101 in the left-right direction, the incident angle of the total reflection surface formed by the light emitting surfaces of the condensers 101 on the two sides is relatively large, and more light can be totally reflected.
