Description

Technical Field

[0001] The present application relates to the technical field of two-wheeled vehicle lights, and in particular to a vehicle light, a method for configuring a vehicle light, and a two-wheeled vehicle comprising the vehicle light. Background Art

[0002] In the Adaptive Front Lighting System (AFS) of a two-wheeled vehicle, the working state of the headlight system (such as the light intensity of the lighting light) is automatically changed according to the road conditions and driving information, thereby providing the driver with a wider range of lighting vision.

[0003] However, due to the limited control accuracy of the existing AFS system on the illumination light beam, it is impossible to accurately adjust the position of the light pattern formed by the illumination light beam, which will lead to uneven illumination range. Figure 1 For example, a two-wheeled vehicle cannot accurately adjust the position of the light pattern formed by the illumination light beam, so that when the two-wheeled vehicle is tilted relative to the ground, the cut-off line (i.e. Figure 1 The outer contour line of the medium light type on the side farthest from the two-wheeled vehicle) is different from the light-and-dark cut-off line of the lighting beam emitted when the two-wheeled vehicle is not tilted, that is, the lighting range of the lighting beam emitted when the two-wheeled vehicle is tilted relative to the ground is different from the lighting range of the lighting beam emitted when the two-wheeled vehicle is not tilted, which makes it impossible to evenly meet the driver's required field of view, thereby affecting driving safety.

When the above-mentioned headlight is applied to a two-wheeled vehicle, the technical problem of the light cutoff line of the illumination light beam emitted when the two-wheeled vehicle is tilted and the light cutoff line of the illumination light beam emitted when the two-wheeled vehicle is not tilted being different can be solved, and the field of vision required by the driver can be met in a more balanced manner, which is beneficial to ensuring driving safety and further beneficial to maintaining public transportation safety.

[0092] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0093] It should be noted that when a component is referred to as being "fixed to" or "mounted on" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. The term "and / or" used herein includes all and any combinations of one or more related listed items. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0094] In order to further explain the technical means and effects adopted by the present application to achieve the intended purpose, the present application is described in detail below in conjunction with the accompanying drawings and preferred implementation methods.

[0095] Please also read Figure 2 and Figure 3 The vehicle lamp 100 of the embodiment of the present application comprises a base 1, a main light source module 2, a plurality of secondary light source modules 3 and a sensing control module 4. The main light source module 2 is used to emit a main illumination light L1. The plurality of secondary light source modules 3 are used to emit secondary illumination lights L2 respectively. The main light source module 2, all the secondary light source modules 3 and the sensing control module 4 are fixed on the base 1.

[0096] The main light source module 2 includes a main shading plate 21, a main light source 22, a main mounting plate 23, a main lampshade 24 and a main lens 25. The main mounting plate 23 is fixed on the base 1, and the main mounting plate 23 includes a main mounting surface 231. The main light source 22 and the main shading plate 21 are fixed on the main mounting surface 231, and the main light source 22 is used to emit the main illumination light L1. The main shading plate 21 and the main lens 25 are sequentially located on the optical path of the main illumination light L1. The extension direction of the main shading plate 21 is parallel to the XY plane in the XYZ rectangular coordinate system. The main shading plate 21 is used to block part of the emission direction of the main illumination light L1 emitted from the main light source 22, so that the main illumination light L1 emitted from the main light source module 2 diverges along the X-axis direction in the XYZ rectangular coordinate system. Specifically, due to the shielding of the main shading plate 21, the shape of the light pattern of the main illumination light L1 is roughly fan-shaped, and the chord S (see Figure 2 ) extends along the X-axis direction, that is, the main illumination light L1 diverges along the X-axis direction; when the main illumination light L1 is projected onto the road surface, the chord S of the fan-shaped light type formed by the main illumination light L1 extends along the X-axis direction, and the side of the chord S of the fan-shaped light type away from the main light source module 2 is not irradiated by the main illumination light L1, while the side of the chord S of the fan-shaped light type close to the main light source module 2 is irradiated by the main illumination light L1, that is, the position of the chord S of the fan-shaped light type forms a clear light-dark boundary, so that the light-dark cut-off line of the light type formed by the main illumination light L1 extends along the X-axis direction.

[0097] The main lampshade 24 is fixed on the base 1, and the main light source 22 and the main mounting plate 23 are covered therein. The inner wall of the main lampshade 24 can reflect the main illumination light L1 emitted from the main light source 22. By providing the main lampshade 24, it is beneficial to better gather the main illumination light L1 on the area to be illuminated, thereby improving the illumination effect. The main lens 25 is installed at the light outlet 241 of the main lampshade 24, and is used to receive and project the main illumination light L1 emitted from the light outlet 241 of the main lampshade 24.

[0098] When the XY plane is parallel to the horizontal ground P, that is, when the extension direction of the main sunshade 21 is not tilted relative to the horizontal ground P, and when the two-wheeled vehicle 900 provided with the headlight 100 of the embodiment of the present application is not tilted relative to the horizontal ground P (placed vertically on the horizontal ground), the light pattern position formed by the main illumination light L1 emitted by the main light source module 2 has a first distance H1 relative to the axis M in the Y-axis direction. Specifically, the first distance H1 is the distance between the midpoint of the chord S of the fan-shaped light pattern formed by the main illumination light L1 and the axis M in the Y-axis direction, wherein the axis M passes through the optical center of the main lens 25 and is perpendicular to the XY plane. The state in which the extension direction of the main sunshade 21 is not tilted relative to the horizontal ground P is defined as the non-tilted state of the headlight 100, and the state in which the extension direction of the main sunshade 21 is tilted relative to the horizontal ground P is defined as the tilted state of the headlight 100.

[0099] The secondary light source modules 3 are symmetrically arranged on both sides of the main light source module 2 and are respectively used to emit the secondary illumination light L2. In other embodiments, the secondary light source modules 3 may also be asymmetrically arranged on both sides of the main light source module 2, which is not limited in the present application. Figure 4 In the illustrated embodiment, the vehicle lamp 100 includes four secondary light source modules 3 symmetrically arranged on both sides of the main light source module 2, and the four secondary light source modules 3 are respectively a first light source module 3a, a second light source module 3b, a third light source module 3c, and a fourth light source module 3d arranged in sequence. The first light source module 3a and the fourth light source module 3d are symmetrically arranged on both sides of the main light source module 2, and the second light source module 3b and the third light source module 3c are symmetrically arranged on both sides of the main light source module 2; the first light source module 3a and the second light source module 3b are arranged on the same side, and the third light source module 3c and the fourth light source module 3d are arranged on the same side. In other embodiments, the vehicle lamp 100 may also include two, six or more secondary light source modules 3, which is not limited in this application.

[0100] Please also read Figure 4 Each secondary light source module 3 includes a secondary shading plate 31, a secondary light source 32, a secondary mounting plate 33, a secondary lampshade 34 and a secondary lens 35. The secondary mounting plate 33 is fixed on the base 1, and the secondary mounting plate 33 includes a secondary mounting surface 331. The secondary light source 32 and the secondary shading plate 31 are fixed on the secondary mounting surface 331. The secondary light source 32 is used to emit the secondary illumination light L2. The secondary shading plate 31 and the secondary lens 35 are sequentially located on the optical path of the secondary illumination light L2.

[0101] The secondary shading plate 31 is used to block part of the emitting direction of the secondary illumination light L2 emitted from the secondary light source 32. The extension direction of the secondary shading plate 31 of each light source module 3 has a non-zero angle relative to the XY plane, so that the divergent direction of the secondary illumination light L2 emitted from the secondary light source module 3 has an angle with the X-axis direction, so that when the vehicle lamp 100 is in a tilted state, each time the secondary illumination light L2 emitted by the light source module 3 also produces a corresponding deviation angle, thereby reducing the angle of the divergent direction of the secondary illumination light L2 at this time relative to the horizontal direction, so that the divergent direction of the secondary illumination light L2 emitted from the secondary light source module 3 at this time is approximately parallel to the horizontal ground. Specifically, due to the shielding of the secondary light shielding plate 31, the shape of the light pattern of the secondary illumination light L2 is also roughly fan-shaped, and the extension direction of the chord S' of the fan-shaped light pattern formed by the secondary illumination light L2 has an angle θ with the X-axis direction, that is, the divergence direction of the secondary illumination light L2 has an angle θ with the X-axis direction, that is, the extension direction of the light-dark cutoff line of the light pattern formed by the secondary illumination light L2 has an angle θ with the X-axis direction. The secondary lens 35 is used to receive and project the secondary illumination light L2 emitted from the secondary light source 32.

[0102] The secondary lampshade 34 is fixed on the base 1, and covers the secondary light source 32 and the secondary mounting plate 33. The inner wall of the secondary lampshade 34 can reflect the received secondary illumination light L2 emitted from the secondary light source 32. By providing the secondary lampshade 34, the secondary illumination light L2 can be better gathered in the area to be illuminated, thereby improving the illumination effect.

[0103] Please also read Figure 2 , Figure 4 and Figure 5 The secondary light source module 3 is configured so that when the XY plane is tilted at a preset angle α relative to the horizontal ground P (i.e., the headlight 200 is in a tilted state, and the extension direction of the main sunshade 21 is tilted at an angle α relative to the horizontal ground P), the position of the light pattern formed by the secondary illumination light L2 is equal to the first distance H1 relative to the axis M in the Y-axis direction. Specifically, the midpoint of the chord S' of the fan-shaped light spot formed by the secondary illumination light L2 is equal to the first distance H1 relative to the axis M in the Y-axis direction.

[0104] In this embodiment, when the XY plane is parallel to the horizontal ground P and the headlight 100 is located above the horizontal ground P, assuming that the optical center of the main lens 25 has a second distance H2 relative to the horizontal ground P, the secondary light source module 3 is configured so that when the XY plane is tilted at a preset angle α relative to the horizontal ground P, the distance of the optical center of the secondary lens 35 relative to the horizontal ground P is equal to the second distance H2, so that the distance H of the position of the light pattern formed by the secondary illumination light L2 relative to the axis M in the Y-axis direction is equal to the first distance H1. The unknown distance Hx of the configured secondary light source module 3 relative to the horizontal ground P in the Z-axis direction satisfies:

[0105]

[0106] Among them, H2 is the distance between the optical center of the main lens 25 and the horizontal ground p, α is the preset inclination angle of the XY plane relative to the horizontal ground p, and L1 is the length of the optical center of the secondary lens 35 relative to the axis M in the X-axis direction.

[0107] In other embodiments, the secondary light source module 3 is configured so that when the XY plane is inclined at a preset angle α relative to the horizontal ground P, the emission direction of the secondary illumination light L2 is parallel to the emission direction of the primary illumination light L1 when the XY plane is parallel to the horizontal ground P.

[0108] The sensing control module 4 includes a sensing element 41 and a control element 42. The sensing element 41 is used to sense the inclination angle of the XY plane relative to the horizontal ground P in real time to generate real-time angle information. The sensing element 41 is arranged parallel to the main sunshade 21, that is, the extension direction of the sensing element 41 is parallel to the XY plane. In this embodiment, the sensing element 41 is a gravity sensor; in other embodiments, the sensing element 41 can also be any one of an acceleration sensor, a direction sensor and a gyroscope, which is not limited in this application.

[0109] The control element 42 is electrically connected to the main light source module 2 and the secondary light source module 3, respectively. The control element 42 is also used to control the switch and working state of the main light source module 2 and the secondary light source module 3 according to the real-time angle information. The working state includes the light intensity of the main lighting light L1 and the light intensity of each lighting light L2, that is, the control element 42 can adjust the light intensity of the main lighting light L1 and the secondary lighting light L2 according to the real-time angle information to further improve driving safety. In other embodiments, the working state may also include the light intensity of the main lighting light L1 and the light intensity of each lighting light L2, which is not limited in this application.

[0110] The vehicle lamp 100 provided in the embodiment of the present application is provided with a main light source module 2 and a secondary light source module 3. When the XY plane is parallel to the horizontal ground P, the position of the light pattern formed by the main illumination light L1 emitted by the main light source module 2 has a first distance H1 in the Y-axis direction relative to the axis M passing through the optical center of the main lens 25 and perpendicular to the XY plane. Please refer to Figure 2 and Figure 6 , by configuring the secondary light source module 3 so that when the XY plane is tilted by a preset angle relative to the horizontal ground P, the distance H of the position of the light pattern formed by the secondary illumination light L2 relative to the axis M in the Y-axis direction is equal to the first distance H1, so that the light pattern position of the main illumination light L1 emitted when the XY plane is parallel to the horizontal ground P and the light pattern position of the secondary illumination light L2 emitted when the XY plane is tilted relative to the horizontal ground P are on the same horizontal line, that is, the midpoint of the chord S of the fan-shaped light pattern formed by the main illumination light L1 emitted by the main light source module 2 and the midpoint of the chord S of the fan-shaped light pattern formed by the secondary illumination light L2 emitted by the secondary light source module 3 when the XY plane is tilted relative to the horizontal ground P are on the same horizontal line. The midpoints of the chord S' of the shaped light pattern are on the same horizontal line parallel to the X-axis, that is, the cut-off line of the main illumination light L1 emitted when the XY plane is parallel to the horizontal ground P and the cut-off line of the secondary illumination light L2 emitted when the XY plane is inclined relative to the horizontal ground P are at the same position. When the above-mentioned vehicle lamp 100 is applied to a two-wheeled vehicle, it can solve the technical problem that the cut-off line of the illumination light beam emitted when the two-wheeled vehicle is tilted and the cut-off line of the illumination light beam emitted when the two-wheeled vehicle is not tilted are different, and the field of vision required by the driver can be met in a more balanced manner, which is beneficial to ensuring driving safety and further beneficial to maintaining public transportation safety.

[0111] The present application also provides a method for configuring a vehicle light.

[0112] See also Figure 7 The configuration method of the vehicle lamp of the first embodiment of the present application is used to configure the main light source module and the secondary light source module of the vehicle lamp as in the above embodiment, including steps S101 to S400:

[0113] Step S100: obtaining primary position information of the primary lens relative to the horizontal ground and secondary position information of the secondary light source module relative to the primary lens module.

[0114] Step S200: Obtain a preset inclination angle of the XY plane relative to the horizontal ground.

[0115] Step S300: Calculate and obtain the secondary position information of the configured secondary light source module relative to the horizontal ground according to the primary position information, the secondary position information and the preset tilt angle.

[0116] Step S400: installing the secondary light source module according to the secondary position information of the secondary light source module relative to the horizontal ground.

[0117] See also Figure 8 Step S100 obtains the main position information of the main lens relative to the horizontal ground and the secondary position information of the secondary light source module relative to the main lens module, specifically including step S101 and step S102:

[0118] Step S101: obtaining a second distance between the optical center of the main lens and the horizontal ground.

[0119] Step S102: obtaining a first length of the secondary light source module relative to the axis of the primary lens in the X-axis direction.

[0120] It should be noted that the order of step 100 and step 200 and step S101 and step S102 can be swapped.

[0121] Please also read Figure 8 and Fig. 9 Specifically, in step S101, a second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P is obtained, and in step S102, a first length L1 of the secondary light source module 3 relative to the axis M of the main lens 25 in the X-axis direction is obtained, and the intersection of the axis M of the main lens 25 and the horizontal ground P is defined as the coordinate origin O, and the distance between the secondary light source module 3 and the coordinate origin O is defined as D B ,

[0122] According to trigonometric function, the first length L1 and the distance D between the secondary light source module 3 and the coordinate origin O are B Satisfies the following formula (2):

[0123] L1=D B ×sinβ (2)

[0124] Wherein, β is the coordinate angle between the secondary light source module 3 and the coordinate origin O when the XY plane is not tilted relative to the horizontal ground P.

[0125] In step S200, a preset tilt angle α of the XY plane relative to the horizontal ground P is obtained. Specifically, the preset tilt angle α is determined according to the needs of the user; for example, the user needs to configure the secondary position information of the secondary light source module 3 relative to the horizontal ground P when the XY plane is 30° relative to the horizontal ground P, that is, the preset tilt angle α is 30°; in other embodiments, the preset tilt angle α can also be any one of 0°-15°, 15°-20°, 20°-40°, 40°-50°, 50°-60°, 60°-80° and 80°-90°, and this application does not limit it.

[0126] The preset tilt angle α, the coordinate angle β, and the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P satisfy the following formula (3):

[0127] H2=D B ×cos(β+α) (3)

[0128] That is, the preset tilt angle is α, the coordinate angle β, and the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P obtained in step S101 also satisfies the following formula (4):

[0129]

[0130] Therefore, if the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P is 500 mm by measurement; the first length L1 of the secondary light source module 3 relative to the axis M of the main lens 25 in the X-axis direction is 50 mm by measurement; and the preset tilt angle α is 15°, by substituting the values ​​of the second distance H2, the first length L1 and the preset tilt angle α into equations (2) and (4), the coordinate angle β between the secondary light source module 3 and the coordinate origin O is 5.41° and the distance D between the secondary light source module 3 and the coordinate origin O is obtained. B It is 533.5mm.

[0131] According to trigonometric function, the unknown distance of the configured secondary light source module 3 relative to the horizontal ground P in the Z-axis direction is defined as Hx. According to trigonometric function, the unknown distance Hx and the coordinate angle β and the distance D between the secondary light source module 3 and the coordinate origin O are B Satisfies the following formula (5):

[0132] Hx=D B ×cosβ (5)

[0133] That is, by combining equations (2), (3) and (5), it can be obtained that the unknown distance Hx of the configured secondary light source module relative to the horizontal ground in the Z-axis direction, the second distance H2 of the optical center of the primary lens relative to the horizontal ground, the preset inclination angle α of the XY plane relative to the horizontal ground, and the first length L1 of the optical center of the secondary lens relative to the axis in the X-axis direction satisfy:

[0134]

[0135] According to the above formula (6), it can be calculated that the unknown distance Hx of the configured secondary light source module 3 in the Z-axis direction relative to the horizontal ground P is approximately 531 mm. According to the secondary position information of the secondary light source module 3 relative to the horizontal ground P (the unknown distance Hx is 531 mm), the secondary light source module 3 is installed at a position approximately 531 mm away from the horizontal ground P.

[0136] The configuration method of the vehicle lamp 100 provided in the first embodiment of the present application obtains the primary position information, the secondary position information and the preset tilt angle, calculates and obtains the secondary position information of the configured secondary light source module 3 relative to the horizontal ground P, and then installs the secondary light source module 3 according to the secondary position information of the secondary light source module 3 relative to the horizontal ground P, so that the light type position of the primary illumination light L1 emitted when the XY plane is parallel to the horizontal ground P and the light type position of the secondary illumination light L2 emitted when the XY plane is tilted relative to the horizontal ground P are on the same horizontal line, thereby making the XY plane parallel to the horizontal ground P. The cut-off line of the main illumination light L1 emitted when the two-wheeled vehicle is parallel and the cut-off line of the secondary illumination light L2 emitted when the XY plane is inclined relative to the horizontal ground P are at the same position. When the vehicle lamp 100 configured using the above-mentioned configuration method of the secondary light source module 3 is applied to a two-wheeled vehicle, it can solve the technical problem that the cut-off line of the illumination light beam emitted when the two-wheeled vehicle is inclined and the cut-off line of the illumination light beam emitted when the two-wheeled vehicle is not tilted are different, and the field of vision required by the driver can be met in a more balanced manner, which is beneficial to ensuring driving safety and further beneficial to maintaining public transportation safety.

[0137] Embodiment 2

[0138] See also Fig.10 The configuration method of the vehicle lamp of the second embodiment of the present application is used to configure the secondary light source module as in the above embodiment, including steps S101 to S400:

[0139] Step S100: obtaining primary position information of the primary lens relative to the horizontal ground and secondary position information of the secondary light source module relative to the primary lens module.

[0140] Step S200: Obtain a preset inclination angle of the XY plane relative to the horizontal ground.

[0141] Step S300: Calculate and acquire the emission direction of the configured secondary illumination light according to the primary position information, the secondary position information and the preset tilt angle.

[0142] Step S400: installing the secondary light source module according to the configured emission direction of the secondary illumination light.

[0143] See also Fig.11 Specifically, step S100 of obtaining the main position information of the main lens relative to the horizontal ground and the secondary position information of the secondary light source module relative to the main lens module specifically includes:

[0144] Step S101: obtaining a second distance between the optical center of the main lens and the horizontal ground.

[0145] Step S102: obtaining a first length of the secondary light source module relative to the axis of the primary lens in the X-axis direction.

[0146] Step S103: obtaining a third distance of the secondary light source module relative to the horizontal ground.

[0147] The difference between the vehicle light configuration method of the second embodiment and the vehicle light configuration method of the first embodiment is that the vehicle light configuration method of the first embodiment obtains the secondary position information of the configured secondary light source module relative to the horizontal ground by calculation, that is, the distance Hx of the secondary light source relative to the horizontal ground is unknown; the vehicle light configuration method of the second embodiment obtains the emission direction of the configured secondary illumination light by calculation, and it is necessary to obtain the third distance H3 of the secondary light source module relative to the horizontal ground, that is, the vehicle light configuration method of the second embodiment calculates the illumination direction of the secondary illumination light on the premise that the distance H of the secondary light source module relative to the horizontal ground is known.

[0148] It should be noted that the order of step 100 and step 200 as well as step S101 , step S102 and step 103 can be swapped.

[0149] Please also read Fig.10 and Fig.12 Specifically, in step S101, the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P is obtained, in step S102, the first length L1 of the secondary light source module 3 relative to the axis M of the main lens 25 in the X-axis direction is obtained, and in step S103, the third distance H3 of the secondary light source module 3 relative to the horizontal ground P is obtained.

[0150] In step S200, a preset tilt angle α of the XY plane relative to the horizontal ground P is obtained. The preset tilt angle α is determined according to the needs of the user; for example, the user needs to configure the secondary position information of the secondary light source module 3 relative to the horizontal ground P when the XY plane is 30° relative to the horizontal ground P, that is, the preset tilt angle α is 30°; in other embodiments, the preset tilt angle α can also be any one of 0°-15°, 15°-20°, 20°-40°, 40°-50°, 50°-60°, 60°-80° and 80°-90°, and this application does not limit it.

[0151] The illumination position of the configured secondary illumination light L2 is defined as Ls in the X-axis direction relative to the axis M of the main lens 25. According to the trigonometric function, the length Ls and the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P satisfy the following formula (7):

[0152] Ls=H2×tanα (7)

[0153] The length of the secondary light source module 3 relative to the axis M of the main lens 25 in the X-axis direction is defined as Lb. According to trigonometric functions, the length Lb and the distance between the secondary light source module 3 and the coordinate origin O are D B Satisfies the following equations (8), (9) and (10):

[0154]

[0155] Lb=D B ×cosγ (9)

[0156]

[0157] According to the preset tilt angle α, the second distance H, the third distance H and the first length, the irradiation direction of the secondary illumination light L2 emitted by the configured secondary light source module 3 is calculated. Specifically, the illumination position of the configured secondary illumination light L2 relative to the secondary lens 35 in the X-axis direction is defined as Lx, and the illumination position of the configured secondary illumination light L2 relative to the secondary lens 35 in the Z-axis direction is defined as Hx. According to trigonometric functions, the length Lx and the length Hx satisfy the following equations (11) and (12):

[0158] Lx=Lb-Ls (11)

[0159] Hx=H2- (sinγ×D B ) (12)

[0160] Therefore, if the second distance H2 of the optical center of the main lens 25 relative to the horizontal ground P is 500 mm by measurement; the first length L1 of the secondary light source module 3 relative to the axis M of the main lens 25 in the X-axis direction is 100 mm by measurement; the preset tilt angle α is 15°, and the third distance H3 of the secondary light source module 3 relative to the horizontal ground P is 450 mm, then it can be obtained by substituting into formula (10): Combining equations (7), (9) and (10), the length Lx of the illumination position of the secondary illumination light L2 relative to the secondary lens 35 in the X-axis direction can be obtained: Therefore, it can be solved that the length Lx of the illumination position of the secondary illumination light L2 after configuration relative to the secondary lens 35 in the X-axis direction is 79 mm, and the length Lx of the illumination position of the secondary illumination light L2 after configuration relative to the secondary lens 35 in the Z-axis direction is defined as =91.1mm.

[0161] Please also read Fig.12 and Fig.13 According to the light distribution test standard of the Economic Commission of Europe (ECE), the irradiation distance standard of the illumination light emitted by the test headlight is 25000mm. Therefore, assuming that the limit irradiation distance of the secondary illumination emitted by the secondary light source module 3 is 25000mm, that is, the maximum irradiation distance of the secondary illumination light L2 emitted by the secondary light source module 3 in the Y-axis direction is 25000mm, then the illumination position of the configured secondary illumination light L2 relative to the length Lx of the secondary lens 35 in the X-axis direction can be combined with the following formula (13) to calculate θ x The optical axis direction of the secondary light source module 3 needs to be tilted 0.18° along the X-axis direction toward the main light source module 2. Specifically, the optical axis direction of the secondary light source module 3 needs to be tilted 0.18° along the negative direction of the X-axis toward the main light source module 2, that is, the secondary light source module 3 as a whole is rotated 0.18° counterclockwise around the Z-axis to obtain the position of the configured secondary light source module 3.

[0162]

[0163] Please also read Fig.12 and Fig.14 θ is calculated by combining the following formula (14) with the illumination position of the secondary illumination light L2 relative to the length Hx of the secondary lens 35 in the Z-axis direction. y , the optical axis direction of the secondary light source module 3 needs to be tilted 0.21° toward the positive direction of the Z axis at the same time, that is, the secondary light source module 3 is rotated 0.21° counterclockwise around the X axis at the same time to obtain the position of the secondary light source module 3 after configuration.

[0164]

[0165] Calculate θ x and θ y , by tilting the secondary light source module 3 toward the main light source module 2 along the X-axis direction by 0.18°, and toward the positive direction of the Z-axis by 0.21°, that is, by rotating the secondary light source module 3 as a whole counterclockwise around the Z-axis by 0.18°, and the secondary light source module 3 as a whole counterclockwise around the X-axis by 0.21°, to obtain the position of the configured secondary light source module 3, so that the emission direction of the secondary illumination light L2 is parallel to the emission direction of the main illumination light L1 when the XY plane is parallel to the horizontal ground P.

[0166] The configuration method of the vehicle lamp 100 provided in the second embodiment of the present application is used to configure the secondary light source module 3 as in any of the above embodiments, and calculate the emission direction of the secondary lighting light L2 after configuration by obtaining the main position information, the secondary position information and the preset tilt angle, and then install the secondary light source module 3 according to the emission direction of the secondary lighting light L2 after configuration, so that the light type position of the main lighting light L1 emitted when the XY plane is parallel to the horizontal ground P and the light type position of the secondary lighting light L2 emitted when the XY plane is tilted relative to the horizontal ground P are on the same horizontal line, thereby making the XY plane parallel to the horizontal ground P. The cut-off line of the main illumination light L1 emitted when the two-wheeled vehicle is moving and the cut-off line of the secondary illumination light L2 emitted when the XY plane is inclined relative to the horizontal ground P are at the same position. When the headlight 100 configured using the configuration method of the secondary light source module 3 is applied to a two-wheeled vehicle 900, the technical problem of the different cut-off lines of the illumination light beam emitted when the two-wheeled vehicle 900 is tilted and the illumination light beam emitted when the two-wheeled vehicle 900 is not tilted can be solved, and the field of vision required by the driver can be met in a more balanced manner, which is beneficial to ensuring driving safety and further beneficial to maintaining public transportation safety.

The midpoint of the chord S' of the fan-shaped light pattern formed by the secondary illumination light L2 emitted by the secondary light source module 3 when tilted is on the same horizontal line parallel to the X-axis, that is, the cut-off line of the main illumination light L1 emitted when the XY plane is parallel to the horizontal ground P and the cut-off line of the secondary illumination light L2 emitted when the XY plane is tilted relative to the horizontal ground P are at the same position, which can solve the technical problem of different cut-off lines of the illumination light beam emitted when the two-wheeled vehicle 900 is tilted and the cut-off line of the illumination light beam emitted when the two-wheeled vehicle 900 is not tilted, and can meet the driver's required field of view in a more balanced manner, which is beneficial to ensuring driving safety and further beneficial to maintaining public transportation safety.
