Description

TECHNICAL FIELD

[0001] The present application relates to a vehicle lamp, in particular, to a lighting module. Furthermore, the present application also relates to a headlamp comprising the lighting module and a vehicle. BACKGROUND

[0002] In recent years, the technical field of vehicle lamp lighting has proposed a pixelated lighting technical solution, the vehicle lamp comprising a pixelated lighting unit and a non-pixelated lighting unit, the pixelated lighting unit projects a pixelated light shape 100, and the non-pixelated lighting unit projects a non-pixelated light shape 200, as shown in FIG. 1, the non-pixelated light shape 200 is generally formed as a high beam widening light shape, i.e., an auxiliary low beam light shape, and the pixelated light shape 100 can form a lighting light shape conforming to different lighting modes by turning on and off the light sources, to realize adaptive high beam or anti-glare high beam functions, as well as low beam cutoff line, pixelated symbol projection to the road surface, etc., as shown in FIG. 2, by turning off a part of the light sources, the pixelated light shape 100 is formed as a main low beam light shape with a low beam cutoff line, and is used for low beam illumination after being superimposed with the non-pixelated light shape 200. Figure 1 Figure 23 As shown in FIG. 3, taking an upper and lower boundary angle difference of the pixelated light shape 100 as 8° as an example, one of the technical solutions is that the upper boundary of the pixelated light shape 100 meets the lighting requirements of adaptive high beam or anti-glare high beam, and the lower boundary meets the requirement of forming a low beam cutoff line, for example, as shown in FIG. 4, when the upper boundary of the light shape is located at +5° and the lower boundary is located at -3°, this technical solution can meet the requirements of pixelated lighting of adaptive high beam or anti-glare high beam at a distance and the formation of a low beam cutoff line, but as shown in FIG. 5, because the position of the pixelated light shape 100 is relatively high, the illumination on the road surface is relatively far away, and the display effect of the pixelated symbol projected to the road surface is poor, because the distance is relatively far, the visibility of the driver is not good enough, and the distortion of the pixelated symbol at a large distance is also relatively large, so the projection effect of the pixelated symbol on the road surface is poor. Another technical solution is that the upper boundary of the pixelated light shape 100 meets the requirement of forming a low beam cutoff line, and the lower boundary meets the requirement of road surface symbol projection, for example, as shown in FIG. 6, when the upper boundary of the light shape is located at +2° and the lower boundary is located at -6°, this technical solution, as shown in FIG. 7, can meet the requirements of road surface symbol projection and the formation of a low beam cutoff line, but as shown in FIG. 8, because the position of the pixelated light shape 100 is relatively low, the illumination on the road surface is relatively close, and the display effect of the pixelated symbol projected to the road surface is poor, because the distance is relatively close, the visibility of the driver is not good enough, and the distortion of the pixelated symbol at a large distance is also relatively large, so the projection effect of the pixelated symbol on the road surface is poor. Figure 1 Figure 2 Figure 3 Figure 4 ​​​​As shown, although it can form a low beam cutoff line and achieve a good effect of road surface symbol projection, it cannot achieve the function of adaptive high beam or anti-glare high beam pixelated lighting because the pixelated light pattern 100 is positioned too low and illuminates the road surface too close, failing to meet the requirements of high beam illumination range. However, if the upper and lower boundary angles of the pixelated light pattern 100 are simultaneously increased to meet both the requirements of adaptive high beam or anti-glare high beam and good road surface symbol projection, the cost of the LED light source, the design difficulty and cost of the lens group, and the space occupied would be significantly increased. Therefore, to overcome the above problems, the position of the pixelated lighting light pattern 100 is usually adjusted vertically according to different lighting modes. However, for modules integrating pixelated and non-pixelated lighting units, the position of the pixelated lighting light pattern 100 is often adjusted vertically. Figure 1 When the high beam mode is switched to low beam mode and the pixelated beam pattern 100 is lowered, the non-pixelated beam pattern 200 is also lowered along with the pixelated beam pattern 100, resulting in the following effect: Figure 6 The dark area 300 shown will affect the low beam lighting effect.

[0065] In the present application, at least one side of the left and right sides of the pixelated lighting part 1 is provided with a non-pixelated lighting part 2, preferably, both left and right sides of the pixelated lighting part 1 are provided with a non-pixelated lighting part 2. In high-beam lighting mode, as shown in Figure 1 , the pixelated light source 11 is all lit to form a pixelated light shape 100 as shown in Figure 1 , the second light source 212 is lit in high-beam lighting mode, the light rays are reflected by the second reflecting unit 232 and then projected from the non-pixelated light-out lens 22 to form a non-pixelated light shape 200 as shown in Figure 22 , the relative position relationship between the pixelated light shape 100 and the non-pixelated light shape 200 is as shown in Figure 1 , the non-pixelated light shape 200 is used for high-beam lighting mode and can form an auxiliary low-beam light shape in low-beam lighting mode, at this time, the upper boundary of the pixelated light shape 100 meets the lighting requirements of adaptive high-beam or anti-glare high-beam, and the lower boundary meets the requirement of forming a low-beam cutoff line.

[0066] Suppose in high-beam lighting mode, the pixelated light source 11 is all lit to form a pixelated light shape 100 as shown in Figure 1 , the second light source 212 is turned off and the first light source 211 is turned on, the light rays are reflected by the first reflecting unit 231 and then projected from the non-pixelated light-out lens 22 to form a non-pixelated light shape 200 as shown in Figure 23 , at this time, the upper boundary of the pixelated light shape 200 is located above the upper boundary of the non-pixelated light shape 200 as shown in Figure 22The upper boundary of the non-pixelated light shape 200 for the high beam illumination mode is shown above the upper boundary of the pixelated light shape 100, and the relative position relationship between the pixelated light shape 100 and the non-pixelated light shape 200 is as shown in Figure 4 As shown, the non-pixelated light shape 200 will not appear dark area 300 when it is lowered together with the pixelated light shape 100, for example, it is lowered by 3°, and the light shape obtained is as shown in Figure 3 As shown, the light shape meets the regulatory requirements, the upper boundary of the pixelated light shape 100 meets the requirement of forming a low beam cutoff line, and the lower boundary meets the requirement of projecting road signs, so the non-pixelated light shape 200 is used for the low beam illumination mode, and after being lowered together with the pixelated light shape 100, it can form an auxiliary low beam light shape without dark area 300 in the low beam illumination mode.

[0067] It should be noted that when switching from the high beam illumination mode to the low beam illumination mode, as shown in Figure 4 The pixelated light shape 100 and the non-pixelated light shape 200 are lowered together, and in the low beam illumination mode, only part of the pixelated light source 11 is lit, and the light is projected through the imaging lens group 12 and the pixelated light-emitting lens 13 to form a low beam illumination light shape as shown in Figure 24 As shown, the pixelated light shape 100 with a low beam cutoff line in the low beam illumination light shape, the first light source 211 is lit, and the light emitted by the first light source 211 is reflected by the first reflecting unit 231 and then projected from the non-pixelated light-emitting lens 22 to form a non-pixelated light shape 200 as shown in Figure 24 By controlling the lighting and extinguishing of the first light source 211 and the second light source 212, the illumination module of the present application will not appear dark area 300 as shown in Figure 6 Further, the positions of the first reflecting unit 231 and the second reflecting unit 232 are not necessarily limited to the first reflecting unit 231 being above the second reflecting unit 232, but the first reflecting unit 231 can also be arranged below the second reflecting unit 232, and the functions of the respective reflecting units are realized by adjusting the respective light distribution angles, and the modeling is more flexible and variable.

[0068] During the switching from the high beam illumination mode to the low beam illumination mode, a dimming mechanism needs to be provided to dim the illumination module, and as an embodiment of the dimming mechanism, as shown in Figure 25 and Figure 26As shown, the light adjusting mechanism is connected to the lighting module, and the light adjusting mechanism comprises three ball screw assemblies 4, each ball screw assembly comprises a ball screw 41 and a ball nut 42, one end of the ball screw 41 is connected to the heat sink 6 through the ball nut 42, and the other end is connected to a light adjusting actuator 5 fixed on the lamp body or a support fixed relative to the lamp body, the other two ball screw assemblies 4 are connected to the heat sink 6 through the ball nut 42 at one end of the ball screw 41, and the other end is fixed on the lamp body or a support fixed relative to the lamp body, the ball centers of the two ball screws 41 form a horizontal light adjusting axis, when the light adjusting actuator 5 arranged on the upper part drives the ball screw 41 connected thereto to move forward and backward, the lighting module can rotate around the horizontal light adjusting axis, and then the lighting module is adjusted upward and downward, so that the pixelated light shape 100 and the non-pixelated light shape 200 of the lighting module move upward and downward as a whole, and the lighting light shape position shown in Figure 4 is adjusted to the lighting light shape position shown in Figure 3 to meet the requirements of the low beam cutoff line and the road surface projection.

[0069] Further, in the present application, the pixelated lighting part 1 and the non-pixelated lighting part 2 are arranged in the same module, and the heat dissipation device is arranged for the module to realize the heat dissipation of the pixelated lighting part 1 and the non-pixelated lighting part 2 as a whole. As a preferred embodiment of the present application, the reflecting surface of the reflecting unit 23 is formed as a parabolic surface, and the lower boundary of the reflecting surface of the reflecting unit 23 is formed as a cutoff line structure, and the light passing through the lower boundary of the reflecting surface of the reflecting unit 23 corresponds to the upper boundary of the auxiliary low beam light shape.

[0070] More preferably, the non-pixelated light emitting lens 22 comprises a non-pixelated light emitting lens light entering surface 221 and a non-pixelated light emitting lens light exiting surface 222, the transverse cross section and the longitudinal cross section of the non-pixelated light emitting lens light entering surface 221 are both rear convex curves, and the curvature of the transverse cross section of the non-pixelated light emitting lens light entering surface 221 is greater than the curvature of the longitudinal cross section.

[0071] Due to the curvature of the transverse cross section of the non-pixelated light emitting lens light entering surface 221 being greater than the curvature of the longitudinal cross section, the non-pixelated light emitting lens light entering surface 221 is formed as a rear convex surface with the central region convex to the surrounding edges, and after the light reflected by the first reflecting unit 231 and the second reflecting unit 232 exits through the non-pixelated light emitting lens 22, the spread light shape with a left-right angle range greater than an up-down angle range can be formed, which meets the regulatory requirements of the low beam lighting.

[0072] As another preferred embodiment of the present application, the number of the first reflecting units 231 is two, the two first reflecting units 231 are arranged along the left-right direction, the number of the second reflecting unit 232 is one, and the first reflecting unit 231 and the second reflecting unit 232 are mirrors. The first reflecting unit 231 arranged above is turned on in the low beam illumination mode, corresponding to forming the auxiliary low beam light shape in the low beam illumination mode, and the second reflecting unit 232 arranged below is turned on in the high beam illumination mode, corresponding to forming the auxiliary low beam light shape in the high beam illumination mode. It is conceivable that the first reflecting unit 231 and the second reflecting unit 232 can be exchanged in position, and the number of the two can be changed according to the actual light emission requirements.

[0073] As another preferred embodiment of the present application, as shown in Figures 8 to 12 the non-pixelated light-emitting lens light entrance surface 221 includes at least one first light entrance surface 2211 and at least one second light entrance surface 2212 arranged along the up-down direction.

[0074] From Figures 8 to 12 it can be seen that the non-pixelated light-emitting lens light entrance surface 221 includes the first light entrance surface 2211 and the second light entrance surface 2212, the first light entrance surface 2211 and the second light entrance surface 2212 correspond to the first reflecting unit 231 and the second reflecting unit 232, and the first light entrance surface 2211 and the second light entrance surface 2212 are formed as two mutually independent convex curved surfaces, so that the non-pixelated light-emitting lens 22 of the present application can change the shape, curvature, etc. of the first light entrance surface 2211 and the second light entrance surface 2212 according to the actual light emission requirements, making the design of the non-pixelated light-emitting lens light entrance surface 221 more flexible.

[0075] As a specific structural form of the present application, as shown in Figure 15 the angle between the light-emitting surface of the non-pixelated light source 21 and the horizontal plane is 5°-30°. Preferably, the angle between the light-emitting surface of the non-pixelated light source 21 and the horizontal plane is 10°-20°, so that the light emitted by the non-pixelated light source 21 can be reflected by the reflecting unit 23 and enter the non-pixelated light-emitting lens 22 as much as possible, improving the optical efficiency of the illumination module.

[0076] As another specific structural form of the present application, the pixelated light-emitting lens 13 includes a pixelated light-emitting lens light entrance surface 131 and a pixelated light-emitting lens light exit surface 132, and the non-pixelated light-emitting lens light exit surface 222 and the pixelated light-emitting lens light exit surface 132 are formed as a curved surface with continuous curvature, so that the pixelated light-emitting lens 13 and the non-pixelated light-emitting lens 22 have better integrity and better modeling effect. At the same time, as shown in Figures 16 to 21As shown, the non-pixelated light-out lens light-out surface 222 can be formed as a plane or a curved surface, and the curvature of the non-pixelated light-out lens light-out surface 222 formed as a curved surface is small, so that the formed curved surface is relatively flat, which is beneficial to improve the modeling aesthetics and is simple and convenient to process.

[0077] Further specifically, the imaging lens group 12 comprises a first imaging lens 121 and a second imaging lens 122 arranged in sequence from back to front, the first imaging lens 121 is arranged as a double convex lens with both the light-in surface and the light-out surface being outward convex curved surfaces, and the second imaging lens 122 is arranged as a convex-concave lens with the light-in surface being an inward concave curved surface and the light-out surface being an outward convex curved surface.

[0078] In the present application, the first imaging lens 121 is arranged as a double convex lens with both the light-in surface and the light-out surface being outward convex curved surfaces and having positive refractive power, so that the focal length of the first imaging lens 121 is shorter and the diopter is higher, thereby reducing the distance between the first imaging lens 121 and the pixelated light source 11; the second imaging lens 122 is arranged as a convex-concave lens with the light-in surface being an inward concave curved surface and the light-out surface being an outward convex curved surface and having negative refractive power, which can offset and correct the dispersion phenomenon of light rays after refraction by the first imaging lens 121, and also can reduce the distance between the second imaging lens 122 and the first imaging lens 121 and the pixelated light-out lens 13; the pixelated light-out lens 13 is arranged as a double convex lens with both the light-in surface and the light-out surface being outward convex curved surfaces and having positive refractive power, which can reduce the distance between the pixelated light-out lens 13 and the second imaging lens 122, thereby effectively reducing the front and back length of the pixelated lighting part 1, so that the illumination module has small volume and low manufacturing cost. The refractive power of the above-mentioned lens represents the ability of the lens to process light, the positive refractive power represents that the lens can converge the entering light, and the negative refractive power represents that the lens can diverge the entering light. The matching mode of the first imaging lens 121, the second imaging lens 122 and the pixelated light-out lens 13 can effectively offset the dispersion of light in the refraction process, so that the dispersion range of the pixel light shape is small, thereby making the imaging more clear and the light shape effect good.
