Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more particularly to a light-emitting module, automotive lighting, and vehicle. Background Technology

[0002] With the rapid development of urban transportation and the popularization of environmental protection concepts, two-wheeled vehicles such as motorcycles and scooters have become an important choice for short-distance travel due to their lightweight, flexibility, and low energy consumption. In the design of two-wheeled vehicles, the headlights not only bear the basic functions of illumination and signal transmission, but are also an important part of the vehicle's appearance design. The headlight mainly consists of a housing and a light-emitting module housed within the housing. In the design of two-wheeled vehicles, the headlights need to meet the stringent regulatory requirements for light distribution (e.g., low beams must form a clear cutoff line below 0°, and high beams must provide sufficient illumination distance). Therefore, appropriate optical surface structures need to be set on the lens of the light-emitting module to meet regulatory requirements.

[0003] In related technological solutions, the headlights of two-wheeled vehicles generally adopt fisheye lights, in which the lens of the light-emitting module protrudes outward to form an optical surface structure, thereby forming the high and low beam patterns. However, the above structure results in the headlights being large and heavy, making it difficult to meet the requirements of miniaturization and lightweighting, and also increasing the overall weight of the vehicle, affecting the vehicle's range. Utility Model Content

[0004] In order to overcome the above-mentioned defects in related technologies, the purpose of this application is to provide a light-emitting module, a headlight, and a vehicle.

[0016] The surface of the second protrusion facing the high beam reflector includes a third arc-shaped surface and a fourth arc-shaped surface connected together. The thickness of the third arc-shaped surface gradually decreases from the first end of the high beam lens toward the middle of the high beam lens, and the thickness of the fourth arc-shaped surface gradually decreases from the second end of the high beam lens toward the middle of the high beam lens.

[0017] The angle between the second protrusion and the horizontal direction is -3° to 3°; the angle between the second protrusion and the vertical direction is 0° to 5°.

[0019] In one possible implementation, the lens assembly includes a set of low-beam lenses and two sets of high-beam lenses, with the two sets of high-beam lenses located on either side of the set of low-beam lenses.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0044] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] As described in the background section, in related technologies, the lens of the headlight light-emitting module protrudes outward to form an optical surface structure, thereby generating high and low beam patterns. This results in large headlights and heavy weight, making it difficult to meet the requirements for miniaturization and lightweighting, and also increases the overall vehicle weight, affecting the vehicle's range.

[0046] In view of this, the embodiments of this application aim to provide a light-emitting module, a vehicle lamp, and a vehicle. By setting the protrusion inside the lens assembly, the internal space of the light-emitting module is fully utilized, which helps to reduce the weight and size of the vehicle lamp, reduce the weight of the whole vehicle, and improve the vehicle's range.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of the embodiments of this application, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. The first direction X can be the thickness direction when the headlight is in use, the second direction Y can be the width direction when the headlight is in use, and the third direction Z can be the height direction when the headlight is in use.

[0048] In the description of this embodiment, the light pattern refers to the projection shape of the light from the vehicle headlights onto a light distribution screen located 25m directly in front of the vehicle. The cutoff line refers to the boundary line where a significant change in brightness is visually perceived when light is projected onto the light distribution screen.

[0049] Please refer to Figures 1-8 This embodiment provides a light-emitting module, including:

[0050] Light source assembly 100. Exemplarily, the light source assembly 100 can be connected to an external power supply to emit light. The light source assembly 100 may include a low-beam light source and a high-beam light source, both of which can be LED lamps, halogen lamps, etc. The number of low-beam and high-beam light sources can be selected based on needs, for example, based on the number of reflectors and / or lenses. The power of the low-beam and high-beam light sources can also be set based on actual needs, for example, 3W, 4W, 5W, 6W, etc.

[0051] The reflector assembly 200 and the light source assembly 100 are disposed on the incident side of the reflector assembly 200. That is, light emitted from the light source assembly 100 can enter the reflector assembly 200, and the reflector assembly 200 reflects the light emitted from the light source assembly 100, thereby changing the path of the light emitted from the light source assembly 100. In this embodiment, the reflecting surface of the reflector assembly 200 can be a plane, a curved surface, etc.

[0052] A lens assembly 300 is disposed on the exit side of the reflector assembly 200, meaning that light reflected by the reflector assembly 200 can enter the lens assembly 300. A protrusion 400 is formed on the side of the lens assembly 300 facing the reflector assembly 200. The protrusion 400 refracts the light reflected by the reflector assembly 200 to form near and far beam patterns. It is understood that the specific shape of the protrusion 400 can be set as needed. The protrusion 400 can form an optical surface structure on the inner side of the lens assembly 300, thereby causing refraction after light passes through to form the desired beam pattern. The aforementioned near and far beam patterns include any one of the following: near beam pattern, far beam pattern, and combined near and far beam pattern.

[0053] This embodiment provides a protrusion 400 on the side of the lens assembly 300 facing the reflector assembly 200. The protrusion 400 refracts the light reflected from the reflector assembly 200, thereby forming a beam pattern that meets regulatory requirements for both high and low beams. Compared to related technologies, by placing the protrusion 400 inside the lens assembly 300, the internal space of the light-emitting module is fully utilized, which helps reduce the weight and size of the headlight, decrease the overall vehicle weight, and improve the vehicle's range.

[0054] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the reflector assembly 200 is located on the side of the light source assembly 100 away from the lens assembly 300, and the reflector assembly 200 extends above the light source assembly 100; that is, the reflector assembly 200 covers the light source assembly 100, the reflector assembly 200 is located on the side of the light source assembly 100 away from the lens assembly 300 in the first direction X, and in the third direction Z, the reflector assembly 200 extends above the light source assembly 100.

[0055] In this embodiment, the surface of the reflector assembly 200 facing the light source assembly 100 is an arc surface 210, and the distance between the arc surface 210 and the light source assembly 100 gradually increases in the direction towards the lens assembly 300. That is, the distance between the arc surface 210 and the light source assembly 100 gradually increases along the first direction X towards the lens assembly 300. In this embodiment, the projection of the arc surface 210 into the plane formed by the first direction X and the third direction Z is generally parabolic, so that the reflector assembly 200 has only one focal point, and the light source assembly 100 is located at the focal point of the reflector assembly 200.

[0056] Specifically, the reflector assembly 200 of this embodiment includes a set of low-beam reflectors 201 and at least one set of high-beam reflectors 202. The number of low-beam reflectors 201 in each set can be set as needed, for example, it can be equal to the number of low-beam light sources. In this embodiment, each set of low-beam reflectors 201 may include two low-beam reflectors 201, each corresponding to one of the two low-beam light sources. The number of high-beam reflectors 202 in each set can be set as needed, for example, it can be equal to the number of high-beam light sources. In this embodiment, each set of high-beam reflectors 202 may include two high-beam reflectors 202, each corresponding to one of the two high-beam light sources. The focal length of both the low-beam reflectors 201 and the high-beam reflectors 202 in this embodiment is 2-6mm. Through the above structure, this embodiment can make the light reflected by the reflector assembly 200 approximately parallel (i.e., unfocused parallel light).

[0057] Please continue to refer to Figure 2 and Figure 3 The lens assembly 300 of this embodiment includes a set of low beam lenses 310, and the protrusion 400 includes a first protrusion 410 formed on the side of the low beam lens 310 facing the low beam reflector 201.

[0058] like Figure 3 As shown, the surface of the first protrusion 410 facing the near light reflector 201 includes a first arc-shaped surface 411 and a second arc-shaped surface 412 connected to each other. Both the first arc-shaped surface 411 and the second arc-shaped surface 412 are recessed towards the side of the near light lens 310, and the middle part of the first arc-shaped surface 411 and the second arc-shaped surface 412 is the lowest point of the recess.

[0059] The angle between the first protrusion 410 and the horizontal direction (i.e., the second direction Y in the figure) is -30° to 30°. The angle between the first protrusion 410 and the vertical direction (i.e., the first direction X in the figure) is -2° to 0°.

[0060] Figure 7 This is a light pattern diagram of the low beam in this embodiment. In the diagram, the horizontal axis represents the horizontal diffusion angle of the light, with the positive direction representing the right side of the vehicle and the negative direction representing the left side. The vertical axis represents the vertical illumination angle of the light, with the positive direction upwards and the negative direction downwards. The darker the color (e.g., red, orange), the higher the luminous intensity of that area. Combined with... Figure 4 and Figure 7 It can be seen that in this embodiment, all low beam rays are below the 0° cutoff line, thus meeting regulatory requirements. Combined with... Figure 5 and Figure 7 As can be seen, the low beam of this embodiment is mainly distributed between -30° and 30°, thereby meeting the requirement of beam pattern broadening.

[0061] As described above, this embodiment uses a first protrusion 410 with a first arcuate surface 411 and a second arcuate surface 412 recessed towards the low beam lens 310, with the lowest point of the recess at the midpoint of the first arcuate surface 411 and the second arcuate surface 412. Setting the angle between the first protrusion 410 and the horizontal direction to -30° to 30°, combined with the aforementioned low beam reflector 201, ensures that the widening of the low beam meets requirements. Setting the angle between the first protrusion 410 and the vertical direction to -2° to 0°, combined with the aforementioned low beam reflector 201, ensures that the low beam is always below the 0° cutoff line, meeting regulatory cutoff line requirements, and eliminating the need for a cutoff line baffle structure, thus reducing the number of components.

[0062] Please continue to refer to Figure 2 and Figure 3 The lens assembly 300 in this embodiment also includes at least one set of high beam lenses 320, and the protrusion 400 includes a second protrusion 420 formed on the side of the high beam lens 320 facing the high beam reflector 202.

[0063] like Figure 3 As shown, the surface of the second protrusion 420 facing the high beam reflector 202 includes a third arc-shaped surface 421 and a fourth arc-shaped surface 422 connected to each other. The thickness of the third arc-shaped surface 421 gradually decreases from the first end of the high beam lens 320 (the left end of the second direction Y in the figure) toward the middle of the high beam lens 320, and the thickness of the fourth arc-shaped surface 422 gradually decreases from the second end of the high beam lens 320 (the right end of the second direction Y in the figure) toward the middle of the high beam lens 320.

[0064] The angle between the second protrusion 420 and the horizontal direction is -3° to 3°; the angle between the second protrusion 420 and the vertical direction is 0° to 5°.

[0065] Figure 8 This is a diagram illustrating the integrated high and low beam pattern of this embodiment. In the diagram, the horizontal axis represents the horizontal spread angle of the light, with a positive direction representing the right side of the vehicle and a negative direction representing the left side. The vertical axis represents the vertical illumination angle of the light, with a positive direction upwards and a negative direction downwards. Darker colors (such as red or orange) indicate higher luminous intensity in that area. (Combined with...) Figure 6 and Figure 8 As can be seen, the high beam lens 320 in this embodiment can converge the high beam (broaden the high beam by -3° to 3°) and ensure that the luminous intensity of the high beam meets the requirements.

[0066] As described above, this embodiment configures the second protrusion 420 to include a third arcuate surface 421 and a fourth arcuate surface 422 connected to each other, and the thickness of both the third arcuate surface 421 and the fourth arcuate surface 422 gradually decreases from one end of the high beam lens 320 toward the center. The angle between the second protrusion 420 and the horizontal direction is set to -3° to 3° to meet the requirements of the high beam luminous intensity. The angle between the second protrusion 420 and the vertical direction is 0° to 5° to meet the requirements of the high beam.

[0067] In this embodiment, the length of the near-light lens 310 ( Figure 2 The dimension along the second direction Y) is 40-44mm, and the width is ( Figure 1 The dimension (Z-direction) along the middle third axis is 12-14mm, and the thickness is ( Figure 2 The dimension along the first direction X) is 2-5mm. The length of the 320mm high-beam lens ( Figure 2 The dimension along the second direction Y) is 40-44mm, and the width is ( Figure 1 The dimension (Z-direction) along the middle third axis is 12-14mm, and the thickness is ( Figure 2 The dimension along the first direction X) is 2-5mm. The distance between the surface of the lens assembly 300 facing away from the light source assembly 100 and the light source assembly 100 is ( Figure 1 The distance along the first direction X) is 60-90mm.

[0068] In this embodiment, the main parameters of the lens assembly 300 are set within the above-mentioned range, which ensures that the lens assembly 300 achieves an ultra-thin and ultra-narrow effect. This helps to reduce the weight and size of the headlight, reduce the overall weight of the vehicle, and improve the vehicle's range. It is understood that in this embodiment, the surface of the lens assembly 300 facing away from the light source assembly 100 (i.e., the outer surface) can be set as needed, for example, it can be a plane or a curved surface.

[0069] like Figure 2 As shown, the lens assembly 300 of this embodiment includes a set of low beam lenses 310 and two sets of high beam lenses 320, with the two sets of high beam lenses 320 located on both sides of the set of low beam lenses 310.

[0070] The above structure allows the lens assembly 300 to have a better symmetrical effect, which helps to improve the aesthetics of the lens assembly 300.

[0071] Please continue to refer to Figure 1 and Figure 2The light-emitting module in this embodiment also includes a circuit board 500 and a heat sink 600. The light source assembly 100 is disposed on the circuit board 500, and components such as a power supply can also be disposed on the circuit board 500 to provide power to the light source assembly 100. The heat sink 600 is located on the side of the circuit board 500 away from the reflector assembly 200. The structure of the heat sink 600 can be configured as needed, for example, it can be a water-cooled heat sink, an air-cooled heat sink, etc. The heat sink 600 can quickly dissipate the heat generated by the circuit board 500, thereby ensuring the normal operation of the circuit board 500 and the light source assembly 100.

[0072] The light-emitting module in this embodiment also includes a decorative ring 700. The lens assembly 300 is mounted on the decorative ring 700. Exemplarily, the decorative ring 700 has a plurality of mounting holes for mounting the lens assembly 300. The number of mounting holes is consistent with the sum of the number of low beam lenses 310 and high beam lenses 320 in the lens assembly 300. The low beam lenses 310 and high beam lenses 320 can be fixed in the decorative ring 700 by snap-fitting, adhesive bonding, or other methods. The decorative ring 700 is also used to connect with the housing of the vehicle lamp to form a vehicle lamp.

[0073] This embodiment also provides a vehicle light, including a housing, and the light-emitting module described above is disposed inside the housing.

[0074] Because the headlights in this embodiment use the aforementioned light-emitting module, it is beneficial to reduce the weight and size of the headlights, thereby reducing the overall weight of the vehicle and improving its range.

[0075] This embodiment also provides a vehicle including the aforementioned vehicle lights.

[0076] For example, the vehicle in this embodiment can be a two-wheeled vehicle such as a motorcycle or a scooter. Because the vehicle in this embodiment uses the aforementioned headlights, it helps to reduce the overall weight of the vehicle and improve its range.
