Description

Technical Field

[0001] The utility model relates to a vehicle lamp, in particular to a lighting module. In addition, the utility model also relates to a low beam lighting device, a high beam lighting device, a high and low beam lighting device and a vehicle lamp using the lighting module. Background Art

[0002] With the development of social economy, the automobile industry has also developed, and more requirements have been put forward for the functions of car lights. In the lighting device that realizes the lighting function of car lights, a lighting module is usually set to realize various light shapes, thereby obtaining a better lighting effect.

[0003] In a lighting module that realizes the lighting function of a vehicle lamp, a collimating optical element is usually provided to obtain approximately parallel outgoing light rays, such as a hyperbolic collimating lens, the curved surface of which is a rotational curved surface based on the optical axis of the lens, and its imaging characteristics are isotropic.

[0004] However, the light shape of vehicle lighting has anisotropic requirements, for example, the upper and lower lighting angles are small, and the left and right lighting angles are large. For this reason, the vehicle lighting system based on the above-mentioned collimating lens, such as the spherical lens, needs to form a basic light shape with a certain width through the special design of an additional optical system, and then image it onto the road surface through the collimating lens. The structure of such a vehicle lighting system is relatively complex, and the additional optical system and the surface shapes of multiple optical surfaces of the lens' light entrance surface and light exit surface need to be taken into account during the light distribution process. The light distribution process is complicated and cumbersome.

[0005] Moreover, the market has an increasing demand for narrow and long headlights. For example, the size of the light-emitting surface of the lens is limited to 20 mm or less in the vertical direction and 30 mm to 100 mm in the horizontal direction. However, since the light-emitting surface size of the lens in the prior art is relatively large, if the lens is directly reduced or combined with the reduction of optical elements, it cannot meet the requirements of light shape, optical performance and optical efficiency.

[0006] In addition, in the prior art, the above-mentioned collimating lens is often combined with a reflector to form a lighting module. In order to ensure the luminous flux, the reflector often needs to be made very large, which directly leads to an increase in the volume of the vehicle lighting system, which is not conducive to the realization of miniaturization.

[0007] In view of this, it is necessary to design a new type of lighting module. Utility Model Content

[0058] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.

[0059] In the description of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0060] As a basic implementation of the present utility model, Figures 1 to 7 As shown, a lighting module is provided, including a light source 1, a concentrator and a lens 3, the concentrator includes at least two concentrating units 2 connected in sequence, the light source 1 and the concentrating units 2 are arranged correspondingly, the concentrator is arranged to be able to converge the light emitted by the light source 1 and make it enter the lens 3, the lens 3 includes at least one lens light emitting surface 302 and at least two lens light incident surfaces 301, and at least one of the lens light emitting surface 302 and the lens light incident surface 301 is a unidirectional collimating surface.

[0061] The utility model designs the lens so that at least one of the lens light-entry surface 301 and the lens light-exit surface 302 is a unidirectional collimating surface, that is, the light is deflected at the lens light-entry surface 301 and / or the lens light-exit surface 302, and converges in a single direction to form an approximately rectangular lighting light shape, and no additional optical system special design is required, so that the structure of the lighting module is simple, for example, the size of the lens light-exit surface 302 in the vertical direction is allowed to be less than or equal to 20 mm, thereby meeting the needs of narrow and long headlights. In addition, the utility model adopts a condenser composed of at least two condensing units 2 as a primary optical element, and the light source 1 and the condensing unit 2 are correspondingly arranged, which ensures the luminous flux, reduces the volume of the lighting module, and facilitates the realization of miniaturization.

[0062] As a preferred embodiment of the present invention, Figures 1 to 7 As shown, at least one lens light entrance surface 301 is a cylindrical or quasi-cylindrical surface formed by stretching its section line in the horizontal direction x along its section line in the vertical direction z; and / or, the lens light exit surface 302 is a cylindrical or quasi-cylindrical surface formed by stretching its section line in the vertical direction z along its section line in the horizontal direction x. Specifically, the lens light incident surface 301 has the optical characteristic of unidirectional collimation of light in the horizontal direction x, and the lens light exit surface 302 has the optical characteristic of unidirectional collimation of light in the vertical direction z; it should be noted that "horizontal unidirectional collimation" means that in the horizontal section, the section line of the lens light incident surface 301 in the horizontal direction x is a convex curve, which has a converging effect, has a large degree of deflection of light, and can have a certain collimation effect on divergent light, while in the vertical section, the section line of the lens light incident surface 301 in the vertical direction z is a straight line or a curve close to a straight line (when the section line of the lens light incident surface 301 in the vertical direction z is a curve close to a straight line, the lens light incident surface 301 is a quasi-cylindrical surface), which makes the deflection ability of the lens light incident surface 301 for divergent light far less than the deflection ability of the lens light incident surface 301 for divergent light in the horizontal section. , it has no collimating effect. The lens light incident surface 301 has a single-direction collimating effect on the divergent light within the horizontal section position range, that is, the lens light incident surface 301 mainly deflects the light in the horizontal direction x; similarly, "vertical unidirectional collimation" means that in the vertical section, the section line of the lens light exit surface 302 in the vertical direction z is a convex curve, which has a converging effect, has a large degree of deflection of the light, and can have a certain collimating effect on the light, while in the horizontal section, the section line of the lens light exit surface 302 in the horizontal direction x is a straight line or a curve close to a straight line (when the section line of the lens light exit surface 302 in the horizontal direction x is a curve close to a straight line, the lens light exit surface 302 is a quasi-cylindrical surface), so that the light deflection ability of the lens light exit surface 302 is far inferior to the light deflection ability of the light exit surface in the vertical section, and it has no collimating effect. Since the lens light incident surface 301 mainly deflects the light in the horizontal direction x, and the lens light exit surface 302 mainly deflects the light in the vertical direction z, the lens light incident surface 301 and / or the lens light exit surface 302 have a unidirectional collimating effect to obtain an approximately rectangular light shape.

[0063] In addition, it should be noted that the present invention does not limit the thickness of the lens 3. The lens 3 can be as follows: Figure 8 The thin lens shown can also be Figures 1 to 7 Thick lens shown.

[0064] As a preferred embodiment of the present invention, Figures 1 to 7As shown, the lens light incident surface 301 is arranged one-to-one with the light focusing unit 2. Specifically, there are multiple lens light incident surfaces 301, which can adjust the light passing through the lens light incident surface 301 respectively, and there are also multiple light focusing units 2. The light focused by the light focusing unit 2 is then adjusted by the corresponding lens light incident surface 301, and the light distribution is more convenient.

[0065] As a preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 6 As shown, the light focusing unit 2 is a first light focusing unit, and the first light focusing unit has a first light focusing portion 201 and a light passing portion 202. The light emitted by the light source 1 enters the first light focusing unit through the light incident surface of the first light focusing portion 201, and is emitted after being transmitted through the light passing portion 202. Specifically, as shown in the figure, the light focusing unit 2 can be a first light focusing unit having a light passing portion 202, and the light passing portion 202 has a certain length, and the light is emitted after being transmitted in the light passing portion 202.

[0066] Or, if Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the light focusing unit 2 is a second light focusing unit, and the second light focusing unit has a second light focusing portion 203. The light emitted by the light source 1 enters the second light focusing unit through the light incident surface of the second light focusing portion 203, and is emitted from the second light focusing portion 203. Specifically, the second light focusing unit does not have a light-through portion of a certain length. After being incident from the light incident surface of the second light focusing portion, the light is only concentrated by the second light focusing portion 203 connected to the light incident surface and then emitted. The second light focusing unit is smaller in size than the first light focusing unit.

[0067] It should be noted that, in the present invention, the shape of the light-focusing unit is not limited, and a transparent light-guiding member with a light-focusing function can meet the design requirements.

[0068] As a preferred embodiment of the present invention, Figures 1 to 7 As shown, in the concentrator, at least two focusing units 2 are integrally formed, and the light-emitting surfaces of the focusing units 2 are connected to form a smooth curved surface or plane. Specifically, there are multiple focusing units 2, and the integrally formed setting is convenient for processing and installation, and reduces the installation structure of parts. Moreover, after the focusing units 2 are integrally formed, the light-emitting surfaces of the focusing units 2 are connected to form a smooth curved surface or plane, which is convenient for the connection between the sub-light shapes, and prevents the sub-light shapes corresponding to each focusing unit 2 from having dark areas when connected.

[0069] As a preferred embodiment of the present invention, Figures 1 to 7As shown, in the lens 3, at least one lens light-emitting surface 302 is connected to form a smooth curved surface or plane. Specifically, connecting the lens light-emitting surfaces 302 to form a smooth curved surface or plane not only has the beneficial effect of preventing the corresponding sub-light shapes from having dark areas when connected, but also makes the appearance of the lens more beautiful when the module is observed from the outside of the headlight.

[0070] The lighting module provided by the utility model can be used in a lighting device. The lighting module can be used as any module such as high beam, low beam, auxiliary high beam, corner light, fog light, etc. in the lighting device. When the lighting device includes multiple lighting modules, it can realize multiple lighting functions such as low beam and high beam, low beam and ADB high beam, main low beam and auxiliary low beam, etc. According to different lighting functions, the lighting device can be divided into a low beam lighting device, a high beam lighting device, a high and low beam lighting device, etc., and the present application does not make any specific restrictions on it.

[0071] For the convenience of description, the low beam lighting device, the high beam lighting device and the high and low beam lighting devices will be schematically described below with reference to the accompanying drawings.

[0072] In one aspect of the embodiment of the present utility model, Figures 1 to 5 As shown, a low beam lighting device is provided, comprising at least one lighting module as described above, and also comprising a low beam cut-off line structure 4 for forming a low beam cut-off line. The light emitted by the light source 1 is converged by the focusing unit 2, cut off by the low beam cut-off line structure 4, and then adjusted by the lens light incident surface 301 and / or the lens light exit surface 302 and projected to form a low beam light shape with a low beam cut-off line. At least one of the lens light incident surface 301 and the lens light exit surface 302 has a unidirectional collimation function to adjust the light.

[0073] Furthermore, the low beam cut-off line structure 4 is a main low beam cut-off line structure and / or an auxiliary low beam cut-off line structure. Specifically, in the same lighting module, a main low beam cut-off line structure for forming a main low beam light-dark cut-off line and an auxiliary low beam cut-off line structure for forming an auxiliary low beam light-dark cut-off line can exist simultaneously or separately.

[0074] Alternatively, if Figures 1 to 4 As shown, the low beam cut-off line structure 4 is arranged at the lower boundary of the light-emitting surface of the concentrator, and the focus of the lens 3 is located at or near the low beam cut-off line structure 4. In order to realize the low beam light-dark cut-off line, the cut-off line structure 4 can be directly cut at the lower boundary of the light-emitting surface of the concentrator. The focusing unit 2 of the concentrator is not limited to the first focusing unit with a light-transmitting portion or the second focusing unit without a light-transmitting portion, and the low beam light-dark cut-off line can be realized by cutting the low beam cut-off line structure 4; the focus of the lens 3 is arranged at or near the low beam cut-off line structure 4, so that the formed low beam light-dark cut-off line is clear, and "near" here refers to the range of 2mm around the low beam cut-off line structure.

[0075] Alternatively, if Figure 5 As shown, the low beam lighting device includes a first light shielding plate 5, a low beam cut-off line structure 4 is arranged at the front end boundary of the first light shielding plate 5, the first light shielding plate 5 is arranged in the light path between the condenser and the lens 3, and the focus of the lens 3 is located at or near the low beam cut-off line structure 4. Specifically, the low beam light and dark cut-off line can also be realized by arranging the first light shielding plate 5 having the low beam cut-off line structure 4, and the focus of the lens 3 is arranged at or near the low beam cut-off line structure 4, so that the low beam light and dark cut-off line is clear, and "near" here refers to within 2 mm around the low beam cut-off line structure.

[0076] Furthermore, the low beam lighting device further includes a second sunshade 6 for preventing sunlight from focusing, and the second sunshade 6 is disposed below the first sunshade 5 and is fixedly connected to the first sunshade 5. Specifically, the second sunshade 6 is used as a sunshade for preventing sunlight from focusing, and can also be fixedly connected to the first sunshade 5 and used as a fixing bracket for the first sunshade 5, thereby saving the installation structure of the first sunshade 5.

[0077] Optionally, the low-beam lighting device may further include a plurality of lighting modules, whereby the sub-light shapes formed by each of the plurality of lighting modules are superimposed to serve as the low-beam light shape of the low-beam lighting device.

[0078] As a preferred embodiment of the utility model, the low beam lighting device includes two lighting modules, namely a main low beam module and an auxiliary low beam module, wherein the main low beam module can emit a main low beam light shape, and the auxiliary low beam module can emit an auxiliary low beam light shape. Specifically, the main low beam module and the auxiliary low beam module respectively include a plurality of light sources 1, a plurality of focusing units 2 and a lens 3, wherein the focusing units 2 are arranged in a horizontal direction and integrally formed, and the lens light incident surface 301 has a plurality of light sources 1 and corresponds to the focusing units 2. The light source 1 is emitted through the focusing unit 2 and the lens 3 to form a plurality of sub-light shapes, and the plurality of sub-light shapes are combined to form a main low beam light shape or an auxiliary low beam light shape having a low light-dark cutoff line.

[0079] The low beam shape of the low beam lighting device can be obtained by superimposing the main low beam shape and the auxiliary low beam shape. The main low beam shape can improve the central brightness of the low beam shape, and the auxiliary low beam shape can better widen the low beam shape.

[0080] Of course, multiple lighting modules can be arranged horizontally or vertically. This application does not impose any special restrictions on this and can be reasonably arranged according to needs.

[0081] Optionally, the main low beam module and the auxiliary low beam module are arranged in a transverse direction, and the arrangement direction of the lighting module is parallel to the arrangement direction of the focusing unit.

[0082] Another aspect of the present invention provides a high beam lighting device, such as Figure 6 , Figure 7 As shown, it includes at least one of the above-mentioned lighting modules. The light emitted by the light source 1 is converged by the condenser, and then adjusted by the lens light incident surface 301 and the lens light emitting surface 302 to form a high beam light shape.

[0083] Optionally, the high-beam lighting device may further include a plurality of lighting modules, whereby the sub-light shapes formed by each of the plurality of lighting modules are superimposed to serve as the high-beam light shape of the high-beam lighting device.

[0084] For example, the high beam lighting device includes two lighting modules, namely a main high beam module and an auxiliary high beam module, wherein the main high beam module can emit a main high beam light shape, and the auxiliary high beam module can emit an auxiliary high beam light shape. Specifically, the main high beam module and the auxiliary high beam module respectively include a plurality of light sources 1, a plurality of light focusing units 2 and a lens 3, wherein the light focusing units 2 are arranged in a horizontal direction and formed as one piece, and the lens light incident surface 301 has a plurality of light sources 1 and corresponds to the light focusing units 2. The light source 1 emits a plurality of sub-light shapes through the light focusing unit 2 and the lens 3, and the plurality of sub-light shapes are combined to form a main high beam light shape or an auxiliary high beam light shape.

[0085] The main high beam light shape and the auxiliary high beam light shape are superimposed to obtain the high beam light shape of the high beam lighting device. The main high beam light shape can improve the central brightness of the high beam light shape, and the auxiliary high beam light shape can make the high beam light shape wider. Of course, in other embodiments, the multiple focusing units 2 in the lighting module can correspond to a lens light incident surface 301 for ADB high beam lighting.

[0086] Of course, multiple lighting modules can be arranged horizontally or vertically. This application does not impose any special restrictions on this and can be reasonably arranged according to needs.

[0087] Optionally, the main high beam module and the auxiliary high beam module are arranged in a transverse direction, and the arrangement direction of the lighting module is parallel to the arrangement direction of the focusing unit.

[0088] Another aspect of the present invention provides a high and low beam lighting device, such as Figures 9 to 13 As shown, the high and low beam lighting device includes two of the above-mentioned lighting modules, one of which is a low beam lighting module capable of forming a low beam light shape, and the light source 1 is a low beam light source 101 ; the other lighting module is a high beam lighting module capable of forming a high beam light shape, and the light source 1 is a high beam light source 102 .

[0089] As a preferred embodiment of the present invention, the low beam lighting module and the high beam lighting module share the same lens 3, and the lens 3 is divided into a low beam lens area and a high beam lens area. Fig.13 As shown, the high and low beam lighting device is divided into a low beam lighting module and a high beam lighting module by a dotted line.

[0090] Optionally, the low beam lighting module and the high beam lighting module can be arranged horizontally or vertically. Figures 10 to 13 As shown, when arranged longitudinally, the low beam lighting module is arranged above the high beam lighting module. Fig.13 As shown, the condenser of the low beam lighting module and the condenser of the high beam lighting module can be integrally formed to save the installation structure. It should be noted that the type of condenser is not limited.

[0091] Optionally, in order to save the cost of the circuit board 7, as Figures 10 to 13 As shown, the low-beam light source and the high-beam light source are arranged on the same circuit board 7. At the same time, with this arrangement, only one radiator 9 is required to dissipate heat from the light source 1, thereby achieving efficient heat dissipation and saving installation space.

[0092] The lens 3 can be mounted on a mounting surface (which can be a mounting surface of the heat sink 9) through a lens bracket 8. The lens bracket 8 is mounted on the mounting surface through a fastener 10. In the high and low beam lighting device, a baffle 11 is also provided between the lens 3 and the condenser to prevent light from crossing, which is used to prevent the low beam from being incident on the lens area corresponding to the high beam, and also to prevent the high beam from being incident on the lens area corresponding to the low beam.

[0093] As another basic implementation of the present invention, a control system for a high and low beam lighting device is provided, and the control system is used to control the high and low beam lighting device, and the control system includes a control unit respectively connected to a plurality of low beam light sources 101 and a plurality of high beam light sources 102, and the control unit is used to: when forming a low beam light shape, control the low beam light source 101 to turn on and control the high beam light source 102 to turn off; when forming a high beam light shape, control the high beam light source 102 to turn on and control part of the low beam light sources 101 to turn off, so that the total power forming the high beam light shape is the same as the total power forming the low beam light shape.

[0094] According to the utility model, the number of low beam light sources 101 is greater than the number of high beam light sources. Exemplarily, the number of low beam light sources 101 can be set to four, and the number of high beam light sources 102 can be set to two, the low beam light sources 101 are arranged above the high beam light sources 102, and the power of each high beam light source 102 is consistent with that of each low beam light source 101. When forming a low beam light shape, the control unit controls all low beam light sources 101 to turn on, and controls all high beam light sources 102 to turn off. When forming a high beam light shape, the control unit controls all high beam light sources 102 to turn on, and controls two low beam light sources 101 to turn on, and two low beam light sources 101 to turn off, so that the total power forming the high beam light shape is the same as the total power forming the low beam light shape. While having the advantages of the above-mentioned lighting device, it is also possible to reduce the maximum total power of the lighting device when realizing the high beam function, reduce the design requirements of the thermal system, and make the lighting device cost lower. Alternatively, the power of each high beam light source 102 and each low beam light source 101 is inconsistent, as long as the total power forming the low beam light shape is the same as the total power forming the high beam light shape. For example, the number of low beam light sources 101 is set to six, the number of high beam light sources 102 is set to two, the power of each low beam light source 101 is 2 watts, and the power of each high beam light source 102 is 4 watts. When the high beam function is realized, the four low beam light sources need to be turned off so that the total power forming the low beam light shape and the total power forming the high beam light shape are the same, which is 12 watts.

[0095] In a specific embodiment of the present invention, the low beam light source 101 includes a main low beam light source for contributing to the central brightness of the low beam light shape and an auxiliary low beam light source for contributing to the widening of the low beam light shape. The control unit is used to: when forming the high beam light shape, control the high beam light source 102 to turn on, control part of the main low beam light source to turn off, and control the auxiliary low beam light source to turn on. This can prevent the light shape from being insufficiently widened to the left and right when the high beam function is turned on, resulting in insufficient left and right range of high beam illumination, that is, under the high beam function, only part of the main low beam light source is turned off, and the brightness of the high beam light shape at the intersection of the HH axis and the VV axis on the light distribution screen still meets the requirement of greater than 80% E max The regulatory requirements of the value are met, and the left and right widening of the light shape is not affected. Without affecting the user experience, the maximum medium power of the lighting device can be effectively reduced, the design requirements of the thermal system can be reduced, and the cost of the lighting device can be lowered.
