Description

Technical Field

[0001] The present application relates to the technical field of vehicle manufacturing, and particularly relates to a lamp and a vehicle. Background Art

[0002] In current lamp designs, the shapes are becoming more and more diverse, and the use of thick-wall lenses is also becoming more and more common. Exemplarily, thick-wall lenses can be seen in lamps such as position lamps, turn signals, brake lamps, and rear fog lamps of vehicles.

[0003] In related technologies, considering the uniformity of lamp light emission, in the direction of light emission (specifically, the direction in which light emits from the lamp), the size of the thick-wall lens needs to be greater than 35 mm. At the same time, in the direction perpendicular to the light emission, the size of the thick-wall lens needs to be not greater than 12 mm. This results in a large space requirement for the lamp in the light emission direction and also limits the shape design of the light-emitting area of the lamp. Summary of the Invention

[0004] In view of this, the present application provides a lamp, which can shorten the space requirement of the lamp in the direction of light emitting from the lamp. At the same time, it can also increase the size of the thick-wall lens in the direction perpendicular to the light emitting from the lamp, thereby making it more convenient for the shape design of the lamp. In addition, the present application also provides a vehicle including the above lamp.

[0005] To achieve the above object, the present application provides the following technical solutions:

[0006] A lamp, comprising a light source, a light homogenizing mask, a reflector, and a thick-wall lens;

[0007] The light source is located on one side of the thick-wall lens along a first direction;

[0008] The thick-wall lens has a first light homogenizing part, which is disposed opposite to the reflector and is used for scattering the light emitted by the light source into the thick-wall lens to the reflector;

[0009] The reflector, the thick-wall lens, and the light homogenizing mask are arranged in sequence. The surface of the reflector facing the thick-wall lens is a reflecting surface, and the arrangement direction of the reflector, the thick-wall lens, and the light homogenizing mask forms a non-zero angle with the first direction.

[0010] Optionally, the thick-wall lens includes:

[0011] A thick-wall lens body;

[0012] The first light homogenizing part is a convex structure on the surface of the thick-wall lens facing the reflector.

[0013] Optionally, a reflective protrusion protruding towards the side of the light homogenizing mask is provided on the part of the thick-walled lens close to the light source; and / or, a light-blocking part capable of absorbing light is provided on the side of the thick-walled lens away from the light source.

[0014] Optionally, the light homogenizing mask includes a light-shielding part, and in the arrangement direction of the reflector, the thick-walled lens and the light homogenizing mask, the projections of the light source and the reflective protrusion on the light homogenizing mask both fall within the light-shielding part.

[0015] Optionally, it includes a circuit board, the light source is fixed on the fixing surface of the circuit board, the thick-walled lens is arranged obliquely relative to the fixing surface, and in the direction perpendicular to the fixing surface, the projection of the first light homogenizing part on the fixing surface at least covers a part of the area where the light source is arranged.

[0016] Optionally, the reflector includes:

[0017] A reflector body;

[0018] A second light homogenizing part, located on the side of the reflector body facing the thick-walled lens and including the reflective surface.

[0019] Optionally, the second light homogenizing part is a frosted aluminized layer.

[0020] Optionally, the first light homogenizing part is a convex structure on the surface of the thick-walled lens facing the reflector;

[0021] The distance between the first light homogenizing part and the second light homogenizing part is 2 mm - 5 mm.

[0022] Optionally, a bracket for fixing the thick-walled lens and the light source is provided on the reflector.

[0023] Optionally, a flanging extending in the direction away from the light homogenizing mask is provided on the side of the thick-walled lens close to the light source, and a first fixing structure for fixedly connecting the bracket is provided on the flanging.

[0024] Optionally, a second fixing structure is provided on the side of the thick-walled lens away from the light source, and the second fixing structure is used to connect the bracket; and / or

[0025] The distance between the light source and the thick-walled lens is 0.5 mm - 1 mm.

[0026] A vehicle includes the lamp according to any one of the above.

[0027] When the lamp provided by this application is in use, the light generated by the light source enters the thick-walled lens. The first light-homogenizing part of the thick-walled lens scatters the light entering the thick-walled lens to the reflector. Since the light-homogenizing mask, the thick-walled lens, and the reflector are arranged in sequence, the light reflected by the reflector needs to pass through the thick-walled lens again to enter the light-homogenizing mask. In this embodiment, the first light-homogenizing part on the thick-walled lens is arranged opposite to the reflector, and the surface of the reflector facing the thick-walled lens is the reflecting surface. That is to say, in this embodiment, the first light-homogenizing part is arranged opposite to the reflecting surface. Based on this, after the light reflected by the reflector enters the thick-walled lens, it will pass through the first light-homogenizing part again. In other words, the first light-homogenizing part of the thick-walled lens in this embodiment can homogenize the light generated by the light source twice successively. In addition, after the light enters the light-homogenizing mask, the light-homogenizing mask can also homogenize the light. That is to say, the light emitted by the light source in this embodiment can only be emitted from the light-homogenizing mask after passing through three homogenization processes successively. The setting of the above light-homogenizing structure (including the first light-homogenizing part and the light-homogenizing mask) enables the light to be fully dispersed without passing through a large travel distance, thereby shortening the size of the thick-walled lens in the direction of the light emitting from the lamp and shortening the space requirement of the lamp in the direction of the light emitting from the lamp. At the same time, it can also increase the size of the thick-walled lens in the vertical direction of the light emitting from the lamp, which is more convenient for the shape design of the lamp.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0036] As Figure 1 - Figure 2 shown, an embodiment of the present application discloses a lamp, which includes a housing (i.e., the outermost protective structure of the lamp, not shown in the figure), and a light source 3, a light homogenizing mask 1, a reflector 5, and a thick-walled lens 4 disposed inside the housing. Among them:

[0037] The light source 3 is the core component that directly generates light radiation in the lamp, usually composed of an electroluminescent element (such as an LED chip, a phosphor excitation unit) or a thermal radiation element (such as a tungsten wire), and converts electrical energy into visible light.

[0038] The light homogenizing mask 1 is an optical component installed on the light-emitting surface of the lamp. Its surface performs multiple refraction-scattering effects on the original light source 3 through microstructural design (such as a prism array, scattering particle doping), effectively eliminating local light spots and improving the spatial uniformity of the emitted light.

[0039] The reflector 5 is a structural member disposed inside the lamp and capable of reflecting light (for the specific implementation manner of the reflector 5, please refer to the following text).

[0040] The thick-walled lens 4 is a light guiding structure disposed inside the lamp. It realizes the directional conduction of light through the total reflection principle and is used to improve the illumination uniformity. In addition, the thick-walled lens 4 can also be used as a carrier for the lamp shape design. Specifically, in the implementation process, by adjusting the contour shape of the thick-walled lens 4 or changing the surface shape of the thick-walled lens 4 facing the light-emitting surface of the lamp, the lamp can have different shapes.

[0041] Please continue to refer to Figure 1 and Figure 2 . In this embodiment, the light source 3 is located on one side of the thick-walled lens 4 along the first direction. The thick-walled lens 4 has a first light homogenizing portion 403, which is disposed opposite to the reflector 5 and is used to scatter the light emitted by the light source 3 into the thick-walled lens 4 to the reflector 5; the reflector 5, the thick-walled lens 4, and the light homogenizing mask 1 are arranged in sequence. The surface of the reflector 5 facing the thick-walled lens 4 is a reflecting surface 501, and the arrangement direction of the reflector 5, the thick-walled lens 4, and the light homogenizing mask 1 (for ease of description, the arrangement direction of the reflector 5, the thick-walled lens 4, and the light homogenizing mask 1 will be denoted as the second direction below) has a non-zero angle with the first direction.

[0042] It should be noted that regarding the size of the angle between the second direction and the first direction, in specific implementation, it can be adaptively designed according to needs. This application does not make specific limitations on this, but it should be noted that no matter what the size of the above angle is, it should be ensured that the light emitted by the light source 3 can enter the thick-walled lens 4, and under the light guiding effect of the thick-walled lens 4, it can be directed to a light homogenizing part of the thick-walled lens 4 and the reflecting member 5.

[0043] As Figure 2 shown, when the lamp in this embodiment is in use, the light generated by the light source 3 enters the thick-walled lens 4, and the first light homogenizing part 403 of the thick-walled lens 4 scatters the light entering the thick-walled lens 4 to the reflecting member 5. Since the light homogenizing mask 1, the thick-walled lens 4, and the reflecting member 5 are arranged in sequence, therefore, the light reflected by the reflecting member 5 needs to pass through the thick-walled lens 4 again to enter the light homogenizing mask 1. In this embodiment, the first light homogenizing part 403 on the thick-walled lens 4 is arranged opposite to the reflecting member 5, and the surface of the reflecting member 5 facing the thick-walled lens 4 is the reflecting surface 501. That is to say, in this embodiment, the first light homogenizing part 403 is arranged opposite to the reflecting surface 501. Based on this, after the light reflected by the reflecting member 5 enters the thick-walled lens 4, it will pass through the first light homogenizing part 403 again. In other words, the first light homogenizing part 403 of the thick-walled lens 4 in this embodiment can homogenize the light generated by the light source 3 twice successively. In addition, after the light enters the light homogenizing mask 1, the light homogenizing mask 1 can also homogenize the light. That is to say, in this embodiment, the light emitted by the light source 3 needs to be homogenized three times successively before it can be emitted from the light homogenizing mask 1. The setting of the above light homogenizing structure (including the first light homogenizing part 403 and the light homogenizing mask 1) enables the light to be fully dispersed without a large travel distance, thereby shortening the size of the thick-walled lens 4 in the second direction, shortening the space requirement of the lamp in the second direction, and at the same time, increasing the size of the thick-walled lens 4 in the direction perpendicular to the second direction, which is more conducive to the shape design of the lamp.

[0044] As Figure 1 shown, the thick-walled lens 4 includes a thick-walled lens body and a first light homogenizing part 403.

[0045] The thick-walled lens body is the main structure of the thick-walled lens 4. Specifically, the thick-walled lens body is the part of the thick-walled optical member for realizing light guiding and for shaping.

[0046] The first light homogenizing part 403 is the part of the thick-walled lens 4 for realizing light homogenization.

[0047] Optionally, the first light homogenizing part 403 can be a light homogenizing structure formed on the thick-walled lens body.

[0048] Exemplarily, the first light homogenizing part 403 can be a convex structure (such as a hemispherical array) on the surface of the thick-walled lens 4 facing the reflector 5. When light passes through the convex structure, it diffuses under the refraction and reflection of the convex structure, thereby achieving the purpose of light homogenization.

[0049] Optionally, the first light homogenizing part 403 can also be a light homogenizing layer provided on the thick-walled lens body that can achieve light homogenization.

[0050] Exemplarily, the first light homogenizing part 403 can also be a light homogenizing layer with light diffusing agent particles (such as silica or polymer microspheres, etc.) inside. A number of light diffusing agent particles are arranged at intervals in the light homogenizing layer. When light passes through the light homogenizing layer, it diffuses under the refraction and reflection of the diffusing agent particles, thereby achieving the purpose of light homogenization.

[0051] As Figure 1 and Figure 2 shown, a reflecting convex 401 protruding towards the light homogenizing mask 1 is provided on the part of the thick-walled lens 4 close to the light source 3.

[0052] The reflecting convex 401 refers to a convex structure with a reflecting function.

[0053] As Figure 2 shown, the reflecting convex 401 has a reflecting surface 4011 that can reflect light to the first light homogenizing part 403. During the use of the lamp, since the light emitted by the light source 3 gradually diffuses in all directions during propagation, this causes part of the light emitted by the light source 3 to be unable to shine on the first light homogenizing part 403, thereby causing light loss and even affecting the uniformity of the lamp's light emission; in this embodiment, the reflecting convex 401 is essentially a structure for concentrating light, and it makes more light emitted by the light source 3 shine on the first light homogenizing part 403 through the reflection of the reflecting surface 4011, thereby being able to improve the light emission effect of the lamp.

[0054] In a further preferred embodiment, a reflecting coating (such as an aluminized layer) is coated on the surface of the reflecting convex 401 to improve the reflecting effect of the reflecting convex 401.

[0055] Continuing as Figure 1 and Figure 2 shown, a light blocking part 402 capable of absorbing light is provided on the side of the thick-walled lens 4 away from the light source 3. The setting of the light blocking part 402 can prevent the light emitted by the light source 3 from shining on the light-reflecting structural member (such as the bracket 6) on the side of the thick-walled lens 4 away from the light source 3 and then generating unwanted reflected light, which affects the uniformity of the lamp's light emission.

[0056] Continuing as Figure 1 and Figure 2As shown, the light homogenizing mask 1 includes a light-shielding portion 101. In the second direction (i.e., the arrangement direction of the reflecting member 5, the thick-wall lens 4, and the light homogenizing mask 1), the projections of the light source 3 and the reflecting protrusion 401 on the light homogenizing mask 1 both fall within the light-shielding portion 101.

[0057] The above-mentioned light-shielding portion 101 is the portion of the light homogenizing mask 1 that can prevent light from passing through.

[0058] The setting of the light-shielding portion 101 can prevent the light generated by the light source 3 from directly passing through the light homogenizing mask 1. That is, the light-shielding portion 101 can block the light source 3, thereby avoiding excessive brightness at the position of the light source 3 and affecting the uniformity of the light emission of the lamp. Similarly, as described above, the purpose of setting the reflecting protrusion 401 in the thick-wall lens 4 is to reflect light toward the first light homogenizing portion 403. According to requirements, a reflecting coating will be provided on the surface of the reflecting protrusion 401. On this basis, using the light-shielding portion 101 to block the reflecting protrusion 401 can avoid excessive darkness at the position of the reflecting protrusion 401 and affecting the uniformity of the light emission of the lamp.

[0059] In an alternative embodiment, the light homogenizing mask 1 includes a light-shielding portion 101 and a light-transmitting portion 102, and the light-shielding portion 101 and the light-transmitting portion 102 are an integral part; that is, the light-shielding portion 101 and the light-transmitting portion 102 are integrally formed.

[0060] In an alternative embodiment, the light homogenizing mask 1 includes a light-shielding portion 101 and a light-transmitting portion 102, and the light-shielding portion 101 and the light-transmitting portion 102 are two independent structural members. At this time, the light-shielding portion 101 and the light-transmitting portion 102 can be fixedly connected by connection methods such as screw connection and / or snap connection.

[0061] As Figure 1 shown, the lamp includes a circuit board 2, the light source 3 is fixed on the fixing surface of the circuit board 2, and the thick-wall lens 4 is inclined relative to the fixing surface.

[0062] More specifically, continuing as Figure 1 shown, the thick-wall lens 4 is inclined relative to the fixing surface, and, in the direction perpendicular to the fixing surface, the projection of the first light homogenizing portion 403 on the fixing surface at least covers a part of the area where the light source 3 is arranged.

[0063] In this setting method, since the first light homogenizing portion 403 of the thick-wall lens 4 is located on the direct light path of the light source 3, it can ensure that most of the light is guided to the first light homogenizing portion 403, which is conducive to making full use of the first light homogenizing portion 403 to improve the uniformity of the light emission of the lamp.

[0064] In a preferred embodiment, the projection of the surface of the thick-wall lens 4 facing the reflecting member 5 on the fixing surface covers the area where the light source 3 is arranged.

[0065] AsFigure 1 As shown in Figure 1 , the reflector 5 includes a reflector 5 body and a second light homogenizing part. Among them:

[0066] The reflector 5 body is the main part of the reflector 5.

[0067] The second light homogenizing part is the part of the reflector 5 that can play a role in light homogenization.

[0068] Continuing as Figure 1 shown, in this embodiment, the second light homogenizing part is located on the side of the reflector 5 body facing the thick-walled lens 4 and includes the reflecting surface 501 described above. That is to say, in this embodiment, in addition to the function of reflecting light, the reflecting surface 501 on the reflector 5 also has a light homogenizing function.

[0069] In this embodiment, when the light emitted by the light source 3 enters the thick-walled lens 4, it will be subjected to the first light homogenization treatment when passing through the first light homogenizing part 403. After the first light homogenizing part 403 scatters the light to the reflector 5, when the light is reflected to the first light homogenizing part 403 under the action of the reflecting surface 501, it will also be subjected to the second light homogenization treatment, and when entering the thick-walled lens body through the first light homogenizing part 403, it will be subjected to the third light homogenization treatment. That is to say, in this embodiment, during the process of light propagation between the thick-walled lens 4 and the reflector 5, it will undergo three light homogenization treatments in sequence. In this way, the uniformity of the light emitted can be further improved.

[0070] In an alternative embodiment, the second light homogenizing part is the reflecting surface 501 on the reflector 5. That is to say, the second light homogenizing part only includes the reflecting surface 501.

[0071] In this embodiment, integrating the light homogenizing function of the reflector 5 onto the reflecting surface 501 is beneficial to simplifying the structure of the reflector 5 and reducing the manufacturing cost of the reflector 5.

[0072] In an alternative embodiment, in addition to including the above-mentioned reflecting surface 501, the second light homogenizing part further includes a light homogenizing layer covering the surface of the reflecting surface 501, and this light homogenizing layer is a light-transmitting layer.

[0073] In actual application, the above-mentioned light homogenizing layer can be a layer structure with light diffusing particles (such as silica or polymer microspheres, etc.) arranged at intervals inside. Or, the above-mentioned light homogenizing layer can also be a layer structure with microstructures arranged on the surface.

[0074] In this embodiment, the second light homogenizing part includes two light homogenizing structures. And because the light homogenizing layer covers the surface of the reflecting surface 501, therefore, the light incident on the reflector 5 will undergo three light homogenization treatments in sequence under the action of the light homogenizing layer and the reflecting surface 501. In this way, the uniformity of the light distribution can be further improved, and thus the light emitted by the lamp is more uniform.

[0075] In addition, it should be noted that the reflective surface 501 on the reflector 5 can be the surface formed by the material used to form the reflector 5, that is, the reflector 5 itself is made of a reflective material. In this setting mode, it is beneficial to simplify the preparation process of the reflector 5. Alternatively, the reflective surface 501 on the reflector 5 can also be a reflective coating on the surface of the reflector 5 body. In this setting mode, the range of options for the material of the reflector 5 body is wider, which is more conducive to reducing material costs.

[0076] In a preferred embodiment, the second light homogenizing part is a frosted aluminized layer on the side of the reflector 5 body facing the thick-walled lens 4.

[0077] In this embodiment, by aluminizing, most of the light incident on the reflector 5 can be directly reflected instead of being converted into heat energy or other forms of energy, thereby improving the light output efficiency and helping to increase the brightness of the lamp; at the same time, by setting a frosted surface, a microscopic rough structure is formed on the surface of the aluminized layer, and the light is diffusely reflected after hitting the aluminized layer, so as to achieve the technical purpose of light homogenization.

[0078] In addition, on the basis that the first light homogenizing part 403 is a convex structure on the surface of the thick-walled lens 4 facing the reflector 5, the distance between the first light homogenizing part 403 and the second light homogenizing part is 2 mm - 5 mm.

[0079] As described above, there is a gap between the first light homogenizing part 403 and the second light homogenizing part. This gap allows the light to have a certain propagation space after being processed by the first light homogenizing part 403 and the second light homogenizing part, so as to fully diverge, thereby ensuring the light homogenization effect of the first light homogenizing part 403 and the second light homogenizing part. In addition, it can be understood that if the gap between the first light homogenizing part 403 and the second light homogenizing part is too large, part of the light will directly pass through this gap and cannot propagate to the target area (that is, the first light homogenizing part 403 or the second light homogenizing part), resulting in light loss. In this embodiment, the distance between the first light homogenizing part 403 and the second light homogenizing part is limited to 2 mm - 5 mm, which can minimize light loss while ensuring the light homogenization effect of the first light homogenizing part 403 and the second light homogenizing part, thereby improving the light emitting effect of the lamp.

[0080] As Figure 1 shown, a bracket 6 for fixing the thick-walled lens 4 and the light source 3 is provided on the reflector 5. At this time, in addition to being used to adjust the light path, the reflector 5 also serves as a support for fixing the thick-walled lens 4 and the light source 3. In this setting mode, a separate support can be avoided, which can simplify the structure inside the lamp, is beneficial to the reasonable arrangement of the optical components inside the lamp, and reduces the production cost.

[0081] In an alternative embodiment, the reflector 5 and the bracket 6 are an integral part, that is, the reflector 5 and the bracket 6 are a whole.

[0082] In this embodiment, the reflector 5 and the bracket 6 are integrally formed. On the one hand, this can reduce the number of parts, which is beneficial to simplifying the internal structure and improving the assembly efficiency. On the other hand, since there is no secondary processing structure for connection between the reflector 5 and the bracket 6, it is beneficial to improve the overall structural strength and stability, and thus the probability of the lamp failing under long-term vibration can be reduced.

[0083] In an alternative embodiment, the reflector 5 and the bracket 6 are two independent structural members and are fixedly connected by connection means such as gluing and threaded connection.

[0084] In this embodiment, after the reflector 5 and the bracket 6 are separately prepared, they are assembled in the assembly workshop. Since the reflector 5 and the bracket 6 are separately prepared, the material selection for both is more flexible. In specific implementation, the reflector 5 and the bracket 6 can select different materials according to different functional requirements. For example, the reflector 5 can select a material with better reflection effect, while the bracket 6 can select a material with higher strength and lower price. In addition, since the reflector 5 and the bracket 6 are two independent structural members, when one of them is damaged, only the damaged one needs to be replaced separately, which is more convenient for maintenance and replacement and has lower cost.

[0085] It should be noted that the setting position of the bracket 6 on the reflector 5 needs to be adaptively designed according to the optical path design inside the lamp, as well as the setting positions of the thick-walled lens 4 and the light source 3 relative to the reflector 5. Therefore, the specific relative positions of the bracket 6 and the reflector 5 are not limited in the embodiments of the present application. In actual application, it should be ensured that both the thick-walled lens 4 and the light source 3 can be fixed on the bracket 6 without affecting the optical path inside the lamp and the lighting effect of the lamp.

[0086] Correspondingly, in order to facilitate connection with the bracket 6, the thick-walled lens 4 is also provided with a structure for connecting with the bracket 6. Exemplarily:

[0087] In some embodiments, as Figure 1 shown, a flange 404 extending in a direction away from the light homogenizing mask 1 is provided on the side of the thick-walled lens 4 close to the light source 3, and a first fixing structure (not shown in the figure) is provided on the flange 404, and the first fixing structure is used for fixedly connecting the bracket 6.

[0088] According to different connection methods, the specific implementation manner of the first fixing structure can be adaptively adjusted as needed. Exemplarily, when the connection method is bolt connection, the first fixing structure can be a bolt hole.

[0089] In a specific embodiment, as Figure 1As shown, the light source 3 is arranged on the circuit board 2. Along the first direction, the bracket 6 is arranged on the side of the light-emitting component close to the circuit board 2. On the side of the thick-walled lens 4 close to the light source 3, there is a flange 404 extending in the direction away from the light homogenizing mask 1, and this flange 404 extends between the circuit board 2 and the bracket 6. The flange 404 and the circuit board 2 respectively have a first through hole and a second through hole arranged opposite to each other. At the position of the bracket 6 opposite to the first through hole, there is a threaded hole. When fixing, insert a screw through the first through hole and the second through hole and tighten it into the threaded hole on the above-mentioned bracket 6.

[0090] Preferably, on the basis that the thick-walled lens 4 is provided with the above-mentioned first fixing structure, a second fixing structure is further arranged on the side of the thick-walled lens 4 away from the light source 3, and this second fixing structure is used for fixedly connecting with the bracket 6. By arranging fixing structures on both opposite sides of the thick-walled lens 4, the fixing stability of the thick-walled lens 4 can be improved.

[0091] Similarly, according to different connection methods, the specific implementation manner of the second fixing structure can be adaptively adjusted as needed. Exemplarily, when the connection method is snap connection, the first fixing structure can be a connection protrusion and / or a connection groove.

[0092] In an exemplary embodiment, as Figure 1 shown, the bracket 6 includes a first bracket 601 and a second bracket 602. The setting manner of the first bracket 601 can refer to the above text, and the present application will not elaborate here. The second bracket 602 is arranged on the side of the reflecting member 5 away from the circuit board 2 and on the side of the reflecting member 5 facing the light homogenizing mask 1. On the side of the thick-walled lens 4 away from the light source 3, there is a light-blocking portion 402 (the implementation manner of this light-blocking portion 402 can refer to the above text, and the present application will not elaborate here), and the second fixing structure is arranged on this light-blocking portion 402 and can be connected with the second bracket 602. In this setting manner, the second light-blocking portion 402 can block the second fixing structure, thereby avoiding the second fixing structure from affecting the light-emitting effect of the lamp.

[0093] It can be understood that after the light source 3 is powered on, in addition to generating light, it will also generate a certain amount of heat. On this basis, if the distance between the light source 3 and the thick-walled lens 4 is too small, on the one hand, this will affect the heat dissipation effect of the light source 3; on the other hand, this will cause the thick-walled lens 4 to change color, thereby affecting the light transmittance of the thick-walled lens 4.

[0094] In addition, the light emitted by the light source 3 has a certain emission angle, that is, the light emitted by the light source 3 will undergo a certain degree of diffusion. On this basis, if the distance between the light source 3 and the thick-walled lens 4 is too large, some of the light emitted by the light source 3 will not be able to enter the thick-walled lens 4, thereby affecting the overall light-emitting effect of the lamp.

[0095] For the above reasons, in some embodiments, the distance between the light source 3 and the thick-walled lens 4 is 0.5 mm - 1 mm. In this way, on the basis of ensuring the heat dissipation of the light source 3 and avoiding the heat generated by the light source 3 from affecting the thick-walled lens 4, the situation where light directly exits through the gap between the light source 3 and the thick-walled lens 4 can be minimized.
