Description

Technical Field

[0001] The present invention relates to the technical field of automobile lamps, and in particular to a light guide and a lamp module. Background Art

[0002] With the development of automobiles and the continuous improvement of consumers' aesthetic level, people pay more and more attention to the appearance of automobiles. As an important part of the appearance of automobiles, the shape of headlights is becoming more and more varied. In existing automobile headlights, high beam and low beam are integrated in a headlight module. The switching of high beam and low beam is realized by controlling the action of the baffle. The driving mechanism drives the baffle to move, and the baffle blocks part of the light, so that the light forms a clear light-dark boundary in a specific area, that is, the light-dark cutoff line. However, the baffle and its driving mechanism occupy a large space, which indirectly increases the volume of the headlight module and cannot meet user needs. In addition, the driving mechanism needs to be powered on to drive the baffle to move, and the baffle will make a sound when it moves, thereby affecting the user's driving experience and increasing the energy consumption of the headlights. In addition, in actual use, some visible boundaries and light and shadow effects may appear at the intersection of high beam and low beam, thereby affecting the driver's vision and driving safety.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0004] In view of the above-mentioned deficiencies of the prior art, an object of the present invention is to provide a light guide and a vehicle lamp module, aiming to solve the technical problem in the prior art that a baffle is required to form a light-dark cut-off line.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A light guide comprises a light guide body, which has a flat structure, and has one or more light guide parts arranged at the rear end of the light guide body, which are used to guide high beam light into the light guide body, and a notch is arranged at the front end of the light guide body, which is used to avoid part of low beam light, and the edge of the notch forms a light emitting surface of the light guide body, which is used to emit high beam light, and a reflective layer is arranged on the upper surface of the light guide body, which includes a reflective plane, which is used to reflect part of low beam light so that the low beam light forms a clear light-dark cutoff line.

[0007] Furthermore, the notch is an arc-shaped notch, and the light-emitting surface is a curved surface.

[0008] Furthermore, the reflective layer also includes a reflective bevel, which is connected to the reflective plane and is inclined upward along the light emitting direction of the high beam. The reflective bevel is used to reflect part of the low beam to enhance the luminous flux of the low beam 75R area.

[0009] Further, there are two reflection planes, and the two reflection planes are symmetrically arranged on both sides of the light guide part.

[0010] Further, at least two side surfaces of the light guide part are inclined outward along the light-emitting direction of the high beam light.

[0011] Further, there are three light guide parts, and the three light guide parts are arranged in a "pin" shape structure.

[0012] A vehicle headlight module includes a housing, a heat dissipation bracket, a low beam light source board, a low beam reflector, a high beam light source board, a lens, and a light guide as described in any one of claims 1-6. The heat dissipation bracket is arranged inside the housing. The low beam light source board and the low beam reflector are arranged on the upper surface of the heat dissipation bracket. The low beam reflector is used to reflect the low beam light emitted by the low beam light source board. The high beam light source board is arranged at the front end of the heat dissipation bracket. The light guide is arranged on the heat dissipation bracket. The light guide is used to guide the high beam light emitted by the high beam light source board and emit the light in a light-emitting light shape of a certain shape. The lens is arranged on the housing.

[0013] Further, a reflecting surface is arranged on the low beam reflector above the light guide part. The low beam light reflected by the reflecting surface is totally reflected by the plane and the light-emitting surface of the lens in sequence and then enters the lens for refraction and light emission to form the light of the low beam three zones.

[0014] Further, it further includes a portal bracket arranged on the heat dissipation bracket and a fog light source board arranged on the portal bracket. The portal bracket is located above the light guide. A fog light lens is arranged on the lens, and the fog light lens corresponds to the light-emitting position of the fog light source board.

[0015] Further, it further includes a portal bracket arranged on the heat dissipation bracket and a laser lamp arranged on the portal bracket. The portal bracket is located above the light guide. A laser lens is arranged on the lens, and the laser lens corresponds to the light-emitting position of the laser lamp.

[0016] Beneficial effects:

[0017] The present invention provides a light guide. When using the low beam, most of the low beam light directly reaches the lens through the notch for refraction and emission, and a small part of the low beam light enters the lens 7 through the reflection of the reflection plane for total reflection. This part of the low beam light turns back or disappears, so that a clear light and dark cut-off line is formed after the low beam light is emitted. When using the high beam, both the low beam light and the high beam light are emitted. Under the action of the light guide, the high beam light forms a light-emitting light shape of a certain shape and is finally refracted out through the lens to achieve the effect of illuminating a farther distance.

[0018] The present invention also provides a headlight module. Compared with the prior art, by providing a light guide, it is not necessary to use a baffle to form a clear light-dark cutoff line, which can reduce the use of accessories such as baffles and drive mechanisms, effectively reduce the volume of the headlight module, and reduce the energy consumption for switching between low beam and high beam. In addition, without increasing the volume of the headlight module, fog lights and / or laser lights can be added according to actual use needs to meet different use needs.

DETAILED DESCRIPTION

[0031] The present invention provides a light guide and a vehicle lamp module. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present invention and are not used to limit the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present invention. In addition, "first" and "second" are only 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 features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0033] In the present invention, the cut-off line, low beam 75R, and low beam three zones are all terms well known to those skilled in the art. The cut-off line refers to an obvious light-dark dividing line formed by the automobile headlights (especially the low beam) when irradiating, which is used to ensure that the driver can clearly see the road ahead while avoiding dazzling oncoming vehicles. Low beam 75R refers to the illuminance value or illumination effect at a specific angle (usually to the right of 75 degrees) within the illumination range of the low beam; it is one of the important indicators for evaluating the lighting effect and performance of the automobile low beam. The low beam three zones are located after the cut-off line, where the light is relatively weak, forming a dark area (anti-glare area), which is mainly used to illuminate the long-distance road surface and road edge in front of the vehicle, and to reduce glare interference to drivers of oncoming vehicles.

[0034] In the present invention, a1 represents the low beam light that forms the light-dark cutoff line, a2 represents the low beam light that increases the light effect of the low beam 75R zone, a3 represents the low beam light that forms the low beam three zones, and b represents the high beam light. "Front" represents the light emitting direction of the headlight module, and "front" is opposite to "rear".

[0035] See also Figure 1As shown, the present invention provides a light guide, including a light guide body 1, which has a flat structure. The rear end of the light guide body 1 is provided with one or more light guiding parts 11, and the light guiding parts 11 are used to guide the high beam light into the light guide body 1. The front end of the light guide body 1 is provided with a notch 12, and the notch 12 is used to avoid part of the low beam light. The edge of the notch 12 forms a light emitting surface 13 of the light guide body 1, and the light emitting surface 13 is used for the high beam light to emit. The upper surface of the light guide body 1 is provided with a reflective layer 14, and the reflective layer 14 includes a reflective plane 141, and the reflective plane 141 is used to emit part of the low beam light so that the low beam light emits a clear light-dark cutoff line.

[0036] In the above, the low beam light is the light emitted by the low beam light source board 4, on which the first LED chip lamp bead 41 for emitting light is provided, and the high beam light is the light emitted by the high beam light source board 6, on which the second LED chip lamp bead 61 for emitting light is provided.

[0037] like Figure 6 As shown, when the low beam is used, the low beam light source panel 4 emits light, and part of the low beam light emitted by it passes through the notch 12 to reach the lens 7 after being refracted or reflected, and then is emitted after being focused by the lens 7; while part of the light is refracted or reflected to the reflecting plane 141, and the part of the light is reflected by the reflecting plane 141 to the lens 7, and is totally reflected inside the lens 7, and finally returns or disappears, so that a clear light-dark cut-off line is formed after the low beam light is emitted.

[0038] like Figure 7 As shown, when the high beam is used, the low beam light source panel 4 and the high beam light source panel 6 emit light, the high beam light emitted by the high beam light source panel 6 enters the light guide body 1 through the light guide portion 11, the high beam light undergoes total reflection inside the light guide body 1, and finally enters the lens 7 from the light emitting surface 13, the lens 7 focuses the high beam light and emits it, the light guide body 1 gathers the high beam light into a light output pattern with a certain shape to improve its effect of irradiating a longer distance.

[0039] Compared with the existing technology, there is no need to use a baffle to form a clear light-dark cut-off line, which can reduce the use of accessories such as baffles and drive mechanisms, effectively reduce the volume of the headlight module, and reduce the energy consumption for switching between low beam and high beam.

[0040] It should be understood that the low beam and high beam refracted by the lens 7 have an intersection area between their light emitting areas. After this part of the low beam and high beam are mixed, there is no visible boundary or light and shadow at the intersection of the low beam and high beam, so that the driver has a clear field of vision, thereby ensuring driving safety.

[0041] In the above, the lens 7 is preferably a plano-convex lens to achieve the effect of focusing the low beam and the high beam.

[0042] In the above, the light guide 1 is made of transparent materials such as PMMA, PC, PS, etc. to ensure stable and efficient light transmission. The reflective layer 14 can be made of aluminum film, reflective aluminum foil, or reflective sheet to achieve the function of reflecting light on the upper surface of the light guide 1.

[0043] In a preferred embodiment, see Figure 1 The notch 12 is an arc-shaped notch, and the light-emitting surface 13 is an arc-shaped surface. Compared with the polygonal notch 12 and the planar light-emitting surface 13, the area of ​​the notch 12 can be increased, so that more low-beam light can pass through the notch 12 to reach the lens 7, and the area of ​​the light-emitting surface 13 is increased to improve the light effect of the high-beam light.

[0044] In a preferred embodiment, see Figure 1 The reflective layer 14 also includes a reflective bevel 142, which is connected to the reflective plane 141 and is inclined upward along the light emitting direction of the high beam. The reflective bevel 142 is used to reflect part of the low beam to enhance the luminous flux of the low beam 75R area. During the low beam emission process, part of the low beam emitted by the low beam light source panel 4 is refracted or reflected to the reflective bevel 142, and the reflective bevel 142 reflects the part of the light to the lens 7, and finally emits it after being refracted by the lens 7 to enhance the luminous flux of the low beam 75R area, that is, to improve the light effect of the bright area below the light-dark cutoff line. By setting the reflective bevel 142, part of the low beam that cannot smoothly pass through the gap 12 to reach the lens 7 can be effectively utilized to improve the utilization rate of the light emitted by the low beam light source panel 4.

[0045] In the above, the reflection plane 141 is a plane that is nearly parallel to the horizontal plane, or a plane that has a small angle with the horizontal plane; the slope of the reflection slope 142 is greater than the slope of the reflection plane 141. In practical applications, the inclination angles of the reflection plane 141 and the reflection slope 142 should be determined according to actual use requirements, and the specific inclination angles are not limited here.

[0046] Preferably, a step portion 15 is provided in the middle of the top of the light guide 1, so that the height of the right side of the top of the light guide 1 is higher than the height of the left side of the top, so that the light-dark cut-off line has a certain shape, that is, the height of the right side of the light-dark cut-off line is higher than the height of the left side, which improves the driver's field of vision of the right side of the road and facilitates observation of the road conditions and road signs on the right side.

[0047] Furthermore, there are two reflecting planes 141 symmetrically disposed on both sides of the light guide portion 11 to ensure uniform light emission of the low beam, thereby ensuring uniform light in the bright area below the cut-off line.

[0048] In a preferred embodiment, see Figure 1At least two side surfaces of the light guide portion 11 are inclined outwardly along the light emitting direction of the high beam. Through the above arrangement, the light shape of the high beam entering the light guide body 1 is increased, ensuring that after the light guide body 1 guides the high beam to the light emitting surface 13, its light shape can meet the use requirements.

[0049] In a preferred embodiment, see Figure 1 There are three light guides 11, and accordingly, three second LED SMD lamp beads 61 are arranged on the high beam light source plate 6, one second LED SMD lamp bead 61 corresponds to one light guide 11, and by providing multiple second LED SMD lamp beads 61, the brightness of the high beam can be effectively improved. The three light guides 11 are arranged in a "pin" shape, so that the three second LED SMD lamp beads 61 can be closely arranged, and the light emitted does not interfere with each other.

[0050] Similarly, in order to ensure the brightness of the low beam, a plurality of first LED chip lamp beads 41 are provided on the low beam light source panel 4. In this embodiment, there are three first LED chip lamp beads 41.

[0051] In summary, the present invention sets a plurality of light guide parts 11 at the front end of the light guide 1 and sets an arc-shaped light-emitting surface 13 at the rear end to guide the high-beam light to be emitted from the light-emitting surface 13 after being reflected by the light guide 1, thereby forming a light-emitting light shape with a certain shape. In addition, a reflective layer 14 is set on the upper surface of the light guide 1. The low-beam light emitted by the low-beam light source plate 4 reaches the light guide 1 after being refracted or reflected. Most of the low-beam light passes through the notch 12 and directly reaches the lens 7. The lens 7 gathers this part of the low-beam light and emits it. A small part of the low-beam light reaches the reflection plane 141. The reflection plane 141 reflects this part of the low-beam light to the lens 7. The low-beam light is totally reflected in the lens 7 and finally returns or disappears. In this way, a clear light-dark cutoff line is formed after the low-beam light is emitted, and a structure of canceling the baffle to form the light-dark cutoff line is realized. The vehicle light module is small in size and reduces the energy consumption for switching between low-beam and high-beam. Another small part of the low beam reaches the reflecting bevel 142, which reflects this part of the low beam to the lens 7. This part of the low beam is refracted by the lens 7 and then emitted to increase the brightness of the bright area below the cut-off line, thereby increasing the utilization rate of the light emitted by the low beam light source panel 4.

[0052] See also Figure 1-11As shown, the present invention also provides a vehicle light module, including a shell 2, a heat dissipation bracket 3, a low beam light source panel 4, a low beam reflector 5, a high beam light source panel 6, a lens 7, and the light guide, the heat dissipation bracket 3 is arranged in the shell 2, the low beam light source panel 4 and the low beam reflector 5 are arranged on the upper surface of the heat dissipation bracket 3, the low beam reflector 5 is used for refracting the low beam light emitted by the low beam light source panel 4, the high beam light source panel 6 is arranged at the front end of the heat dissipation bracket 3, the light guide is arranged on the heat dissipation bracket 3, the light guide is used for guiding the high beam light emitted by the high beam light source panel 6, and emitting light in a certain shape, and the lens 7 is arranged on the shell 2.

[0053] like Figure 6 As shown, when the low beam is emitted, the low beam light source plate 4 emits low beam light, and all low beam light is reflected by the low beam reflector 5. Most of the low beam light after one reflection passes through the notch 12 to reach the lens 7. The lens 7 focuses this part of the low beam light and emits it. A small part of the low beam light reaches the reflection plane 141 for secondary reflection. The reflection plane 141 reflects this part of the low beam light to the lens 7. This part of the low beam light is totally reflected in the lens 7 and finally turns back or disappears to form a clear light-dark cutoff line. In addition, a small part of the low beam light reaches the reflection bevel 142 for secondary reflection. The reflection bevel 142 reflects this part of the low beam light to the lens 7. The lens 7 refracts this part of the low beam light and emits it. By utilizing the part of the low beam light that cannot directly pass through the notch 12, the brightness of the bright area below the light-dark cutoff line is increased, thereby enhancing the luminous flux of the low beam 75R area of ​​the headlight module.

[0054] like Figure 7 As shown, when the high beam is emitted, the low beam light source plate 4 emits low beam light, and the high beam light source plate 6 emits high beam light, wherein the light emission process of the low beam light source plate 4 is the same as the low beam light emission process described above. The second LED patch lamp bead 61 emits high beam light, and the high beam light enters the light guide body 1 through the corresponding light guide portion 11, and the light guide body 1 guides the high beam light to the light emitting surface 13 for emission. Since the light guide body 1 is a flat structure, all high beam light is emitted through the light emitting surface 13 to form a light emitting light shape with a certain shape. The lens 7 focuses the high beam light with the light emitting light shape and emits it to meet the illumination requirements of the high beam.

[0055] Therefore, by opening the low beam light source panel 4 alone, or opening the low beam light source panel 4 and the high beam light source panel 6 at the same time, the switching between low beam and high beam can be achieved. Compared with the existing technology, the use of accessories such as baffles and driving mechanisms can be reduced, the volume of the vehicle light module can be effectively reduced, and the energy consumption of switching between low beam and high beam can be reduced.

[0056] In a preferred embodiment, see Figure 4 , 5The low beam reflector 5 is provided with a reflective surface 51 located above the light guide 11. The low beam light reflected by the reflective surface 51 is reflected by the plane of the lens 7 and the light emitting surface 13 in sequence, and then enters the lens 7 for refracting and emitting light, so as to form low beam three-zone light. Figure 8 As shown, part of the low beam light emitted by the low beam light source panel 4 reaches the reflecting surface 51 area of ​​the low beam reflector 5, and the reflecting surface 51 reflects this part of the light to the plane of the lens 7, and reaches the light emitting surface 13 after total reflection at the plane of the lens 7, and then returns to the lens 7 after total reflection at the light emitting surface 13 again, and finally emits the light after refraction by the lens 7. This part of the light is located in the third low beam zone, which allows the driver to see the road signs clearly, and the light is not too bright, so it will not cause dazzle to the other driver.

[0057] In the prior art, a baffle is used to block the low beam to form a light-dark cutoff line, so that there is no light in the three low beam zones, thereby affecting the driving safety of the driver.

[0058] In one embodiment, see Fig. 9 , and also includes a gate-shaped bracket 31 arranged on the heat dissipation bracket 3, and a fog light source board 8 arranged on the gate-shaped bracket 31, so that the vehicle light module has the function of turning on the fog light, so as to facilitate the driver to drive in rainy and foggy weather or in an environment with low visibility. The gate-shaped bracket 31 is located above the light guide, and a fog light lens 71 is arranged on the lens 7, and the fog light lens 71 corresponds to the light emitting position of the fog light source board 8. Specifically, a third LED SMD lamp bead is arranged on the fog light source board 8, and a fog light reflector 81 is arranged on the gate-shaped bracket 31, and the opening position of the fog light reflector 81 corresponds to the position of the fog light lens 71. The fog light emitted by the third LED SMD lamp bead is reflected by the fog light reflector 81 and reaches the plane of the lens 7, and finally refracted by the fog light lens 71 to form a light with strong penetrating ability, which can help the driver see the road ahead clearly.

[0059] In another embodiment, see Fig.10 , and also includes a door-shaped bracket 31 arranged on the heat dissipation bracket 3, and a laser lamp 9 arranged on the door-shaped bracket 31, so that the car light module has the function of turning on the laser lamp 9 to emit light with higher brightness and stronger penetrating ability, especially in severe weather conditions such as rain, fog, and sandstorms, which can provide better lighting effects for the driver. The door-shaped bracket 31 is located above the light guide, and a laser lens 72 is provided on the lens 7, and the laser lens 72 corresponds to the light output position of the laser lamp 9. Specifically, there are two laser lamps 9, and the two laser lamps 9 are symmetrically arranged. The laser lamps 9 are arranged horizontally, and the laser light emitted by them directly reaches the plane of the lens 7, and then is emitted after being refracted by the laser lens 72 to form a light with stronger penetrating ability, which can further help the driver see the road ahead.

[0060] In another embodiment, see Fig.11 , and also includes a door-type bracket 31 arranged on the heat dissipation bracket 3, and a fog light light source plate 8 and a laser light 9 arranged on the door-type bracket 31. Specifically, there are two laser lights 9, and the two laser lights 9 are symmetrically arranged on both sides of the fog light light source plate 8, so that the car light module has the function of turning on the fog light and the laser light 9 to meet the user's needs.

[0061] It can be seen that by adding a door-shaped bracket 31 to the heat dissipation bracket 3, the fog lamp and the laser lamp 9 can be installed without increasing the volume of the headlight module, so that the headlight module integrates a variety of lights with different functions to meet user needs.

[0062] In the above, the fog lamp lens 71 and the laser lens 72 are preferably convex lenses to achieve the effect of focusing the fog lamp light and the laser light.

[0063] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
