Description

Technical Field

[0001] The present invention belongs to the technical field of automobiles, and in particular, relates to a lamp and a vehicle. Background Art

[0002] With the development of the automobile industry and the improvement of consumers' aesthetics, more and more attention is paid to the appearance of automobiles, especially automobile lamps, which are the finishing touch of automobile appearance. In order to achieve the beauty of automobile styling and cater to the development trend of the market, the styling of automobile lamps has become more and more complex and avant-garde. With the development of automobile headlight technology and solutions, the internal styling of headlights has become more and more diversified. The combination of a large number of light guides and thick-walled parts, as well as the matching of multiple decorative rings, significantly improves the appearance of the interior of the headlights. For the position lights and daytime running lights inside the headlights, most models currently design them as the highlights of the internal styling of the headlights. From ordinary straight lines and curves, they gradually develop into flat curved surfaces. Larger and larger luminous planes or luminous curved surfaces frequently appear on modern car lights. And according to the development trend of lamp styling, even more complex and tortuous luminous surfaces will appear more and more on car lights. However, the problem of luminous uniformity of larger planes is difficult to solve.

[0003] Current car lights all use small light-emitting surfaces to avoid the problem of uneven light emission from larger light-emitting surfaces. If it is unavoidable to use a larger light-emitting surface, the car light solutions in the field all use the form of mixing light-evening powder into the injection molding material of the inner mask to solve the problem of uneven light emission, or use LEDs to be arranged on one side of a light guide plate to evenly scatter the light through the light guide plate.

[0004] However, the lamps adopting the above solutions will inevitably encounter the problems of low light efficiency and high light loss. They can only be used as position lights and cannot be used as daytime running lights.

[0005] It is desirable to provide an improved lamp, particularly with regard to how to achieve a larger light-emitting surface and uniform light emission, improve light efficiency, and reduce light loss. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a lamp, the purpose of which is to improve light efficiency and reduce light loss.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: the lamp includes a light source, a reflector, and a first inner cover, a second inner cover and an outer cover arranged in sequence along the emitting direction of the light source, and the light source is located between the reflector and the first inner cover.

[0008] The first inner mask is configured to mix the light in the Y direction, and the second inner mask is configured to mix the light in the Y direction and the light in the Z direction again.

[0009] The first inner cover is provided with an inner wall refraction pattern, and the inner wall refraction pattern faces the light source.

[0010] The inner side wall refraction pattern is a Z-direction vertical stripe serrated pattern.

[0011] An outer sidewall scattering pattern is arranged on the first inner face mask, and the outer sidewall scattering pattern faces the second inner face mask.

[0012] The outer side wall scattering pattern is a vertical striped columnar pattern.

[0013] The second inner cover is provided with an inner wall scattering pattern, and the inner wall scattering pattern faces the first inner cover.

[0014] The inner wall scattering pattern is a corn-like pattern.

[0015] The light source is an LED light source, which is arranged on a PCB board, and the PCB board is fastened to the reflector by means of buckles and self-tapping screws.

[0016] The present invention also provides a vehicle, comprising the lamp.

[0017] The lamp of the present invention can solve the problem of achieving uniform light emission on a larger light-emitting surface by arranging a plurality of light-evening masks, thereby improving light efficiency and reducing light loss. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Embodiment 1

[0034] First, as Figures 1 to 6As shown, an embodiment of the present invention provides a lamp, comprising a housing 6, a light source 1, a reflector 2, and a first inner mask 3, a second inner mask 4, and an outer mask 5 arranged in sequence along the light emitting direction of the light source 1, wherein the light source 1 is located between the reflector 2 and the first inner mask 3. The first inner mask 3 is configured to mix the light in the Y direction, and the second inner mask 4 is configured to mix the light in the Y direction and the Z direction again, wherein the Y direction and the Z direction are perpendicular to each other, and the Y direction and the Z direction are perpendicular to the X direction, wherein the X direction is the length direction of the vehicle, the Y direction is the width direction of the vehicle, and the Z direction is the vertical direction.

[0035] Specifically, the embodiment of the present invention aims to solve the problem that a large flat luminous surface has low light efficiency and high light loss and cannot be used as a daytime running light. To this end, the present invention provides a new structure for realizing uniform light emission of a larger luminous surface in a new type of automobile lamp, the purpose of which is to directly use LEDs and reflectors 2 to realize a daytime running light with a larger luminous surface in a smaller space range and to achieve uniform light emission under visual effects in the case of a larger luminous surface.

[0036] like Figures 1 to 6 As shown, the outer cover 5 is mounted at one end of the housing 6, and the light source 1, the reflector 2, the first inner cover 3 and the second inner cover 4 are located inside the housing 6. The second inner cover 4 is located between the first inner cover 3 and the outer cover 5, and the light source 1 emits light from the top, which is reflected by the reflector 2 to convert the point light source 1 into approximately parallel light and emit it to the first inner cover 3 in the front.

[0037] Since the reflector 2 has boundaries, side walls and other forms of barriers, the emitted light is separated into obvious bright and dark areas.

[0038] After the light in the Y direction is mixed by the first inner mask 3 and the light in the Y and Z directions is mixed again by the second inner mask 4, the bright and dark areas in the Y and Z directions are basically mixed evenly.

[0039] Finally, from the perspective of human vision, when looking at the luminous surface of the second inner mask 4 through the outer mask 5, the overall brightness distribution is uniform.

[0040] Through the above steps, the lamp provided by the embodiment of the present invention can solve the problem of achieving uniform light emission on a larger light-emitting surface.

[0041] As a preferred example, Figure 1 As shown, the first inner cover 3 is provided with an inner wall refraction pattern 301, and the inner wall refraction pattern 301 faces the light source 1. The inner wall refraction pattern 301 is a vertical stripe sawtooth pattern in the Z direction.

[0042] As a preferred example, Figure 1As shown, an outer wall scattering pattern 302 is provided on the first inner mask 3, and the outer wall scattering pattern 302 faces the second inner mask 4. The outer wall scattering pattern 302 is a vertical striped columnar pattern.

[0043] As a preferred example, Figure 1 As shown, the second inner mask 4 is provided with an inner wall scattering pattern 401, and the inner wall scattering pattern 401 faces the first inner mask 3. The inner wall scattering pattern 401 is a corn grain pattern.

[0044] like Figure 1 As shown, in the embodiment of the present invention, the key parts are mainly the first inner mask 3 for diffusing light in the Y direction, and the second inner mask 4 for expanding light in the Y and Z directions.

[0045] Light is emitted from the top of light source 1 in the -Z direction, and is reflected by the reflective bowl composed of multiple paraboloids of reflector 2, converting the point light source 1 into approximately parallel light in the -X direction, that is, toward the front of the vehicle.

[0046] Since the reflector 2 has boundaries, side walls and other forms of barriers, the emitted light is separated into obvious bright and dark areas.

[0047] from Figure 6 It can be seen that the reflection bowl of reflector 2 has more dark areas in the Y direction due to large separation, and fewer dark areas in the Z direction due to small separation. The light needs to be mixed more in the Y direction.

[0048] The light passes through the inner wall refraction pattern 301 of the first inner mask 3. The inner wall refraction pattern 301 is a large sawtooth pattern with vertical stripes in the Z direction, which is used to refract the light from the reflector 2 into the first inner mask 3 as much as possible, avoid the light loss due to the reflection of the first inner mask 3, and perform the first refraction along the Y direction and the preliminary mixing of the light along the Y direction. Then the light passes through the outer wall scattering pattern 302 of the first inner mask 3. The outer wall scattering pattern 302 is a vertical striped columnar pattern. The outer wall scattering pattern 302 is used to mix the incoming light in a large range in the Y direction and make the light diverge in the -X direction, that is, toward the front of the vehicle. The light then passes through the inner wall scattering pattern 401 of the second inner mask 4. The inner wall scattering pattern 401 is a corn grain pattern. The inner wall scattering pattern 401 is used to mix the light scattered by the first inner mask 3 in the Y and Z directions.

[0049] After multiple Y- and Z-direction mixing, the light has basically achieved uniform illumination in all directions without obvious dark areas.

[0050] Finally, the outer side of the second inner mask 4 (the side facing the outer mask 5) may not have an optical pattern, or may have a very shallow leather pattern, so that the light emission is very uniform, and the human eye cannot see the dark area and shadow of the internal reflector 2 through the second inner mask 4 from the outside, and there is no visible dark area and shadow when the human eye directly observes when the LED is not lit.

[0051] Finally, there is no optical pattern on the outer cover 5, which provides a good seal and mounting base for the entire lamp.

[0052] In the embodiment of the present invention, the light source 1 is an LED light source, which is arranged on a PCB board, and the PCB board is fastened to the reflector 2 by means of snaps and self-tapping screws. The reflector 2 with the PCB board and the light source 1 is mounted on the housing 6 by means of self-tapping screws. The first inner cover 3 and the second inner cover 4 are fastened to the outer cover 5 by means of self-tapping screws. Finally, the outer cover 5 and the housing 6 are connected together by means of a glue groove, and other accessories form a complete lamp.

[0053] The lamp provided by the embodiment of the present invention has the following beneficial effects:

[0054] 1. Simple process: Adding a layer of uniform light mask on the basis of the normal inner mask makes the process simpler to implement;

[0055] 2. Good appearance: The luminous surface realized by this solution emits light evenly throughout the entire luminous surface. Compared with the single-layer mask solution, the luminous surface of the present invention has no obvious visible shadow area, and there is no problem of shadows caused by various forms of blocking such as the boundary and side walls of the reflector 2 seen through the inner mask;

[0056] 3. Strong practicability: Compared with the common methods of mixing light-leveling powder into the injection molding material of the inner mask to solve the problem of uneven light emission, or arranging LEDs on one side of the light guide plate to evenly scatter the light through the light guide plate, these solutions cannot be applied to daytime running lights due to low light efficiency. This solution can use the LED reflector 2 to reflect the concentrated LED light flux, and there is no light-leveling powder or light guide plate to completely convert the light into diffuse reflection. The light is refracted only through the first inner mask 3 and the second inner mask 4, and the light energy loss is low, so that it can be used for daytime running lights;

[0057] 4. Lower cost: Compared with the common solution of mixing light-leveling powder into the injection molding material of the inner mask to solve the problem of uneven light emission, or arranging LEDs on one side of the light guide plate to evenly scatter the light through the light guide plate, which has high light loss, if you want to achieve the same brightness in the same area, this solution has less light loss, can reduce the number of LEDs used, and has cost advantages.

[0058] In a second aspect, an embodiment of the present invention further provides a vehicle, comprising a lamp of the above structure. The specific structure of the lamp can be referred to Figures 1 to 6 Since the vehicle of the embodiment of the present invention includes the lamp in the above embodiment, it has all the advantages of the above lamp.

[0059] Embodiment 2

[0060] In the embodiment of the present invention, Figures 7 to 9 As shown, the lamp also includes a fixing mechanism 7, which is connected to the housing 6 and is used to install the lamp on the body of the vehicle. The fixing mechanism 7 includes a sheet metal buckle 8, on which a bayonet 9 is provided; the sheet metal buckle 8 is provided with an assembly through hole 15; the bayonet 9 is inserted into the assembly through hole 15 of the sheet metal buckle; the bayonet 9 is connected to the sheet metal buckle 8 through an elastic mechanism; the embodiment of the present invention uses the sheet metal buckle 8, the bayonet 9 and the elastic mechanism in coordination, so that the bayonet 9 can adaptively change its position. In subsequent use, the elastic deformation of the elastic mechanism itself can change the position of the bayonet 9 following the position of the housing 6, so that the bayonet 9 is always connected to the housing 6, so that the fixing mechanism 7 can always have a direct connection relationship with the lamp, and avoid the problem of the lamp being loosened after the distance between the lamp and the vehicle body 16 is reduced.

[0061] The fixing mechanism 7 disclosed in the embodiment of the present invention is used for the installation and fixing of the lamp, and ensures the accuracy and stability of the position of the lamp when it is installed on the vehicle body. Specifically, in the embodiment of the present invention, the fixing mechanism 7 mainly includes a sheet metal buckle 8, which is fixedly installed on the vehicle body 16, and a bayonet 9 is provided on the sheet metal buckle 8, which plays a basic connection role, and the bayonet 9 is plugged into the sheet metal buckle 8, and the bayonet 9 is hung on the shell 6; in subsequent use, the sheet metal buckle 8 in the embodiment of the present invention is provided with an assembly through hole 15; the bayonet 9 is plugged into the assembly through hole 15 of the sheet metal buckle; the bayonet 9 is connected to the sheet metal buckle 8 through an elastic mechanism; the elastic mechanism is mainly used to pull the bayonet 9, and the bayonet 9 can ensure a stable connection between the bayonet 9 and the shell 6 under the pulling of the elastic mechanism.

[0062] At the same time, in the embodiment of the present invention, the function of the elastic mechanism is to connect the bayonet 9 and the sheet metal buckle 8, so as to facilitate the installation and fixation of the bayonet 9 on the sheet metal buckle 8; and because of its own elastic deformation, the bayonet 9 is always subjected to a pulling force. During subsequent use, even if the interval between the taillight housing 11 and the vehicle body 16 becomes smaller; under the pulling of the elastic mechanism, the bayonet 9 will still be connected to the housing 6, thereby ensuring that the fixing mechanism 7 will always be connected to the lamp and the vehicle body 16, thereby ensuring the installation stability of the lamp on the vehicle body 16.

[0063] In addition, in the embodiment of the present invention, the latch 9 can move axially along the sheet metal buckle 8 under the pull of the elastic mechanism; such a configuration ensures that the latch 9 and the housing 6 are always connected, thereby preventing the housing 6 and the latch 9 from being separated.

[0064] Furthermore, in the embodiment of the present invention, the bayonet pin 9 includes a bayonet pin body 19, which is the main structure of the bayonet pin 9, and in the embodiment of the present invention, a limit pull head 14 is provided at the end of the bayonet pin body 19; the limit pull head 14 and the bayonet pin body 19 form a T-shaped structure. During subsequent use, the bayonet pin body 19 is connected to the sheet metal buckle 8 through an elastic mechanism, and the limit pull head 14 acts as a hook, which facilitates the bayonet pin 9 to be hung on the shell 6, thereby realizing the stable installation of the lamp on the vehicle body 16.

[0065] Meanwhile, in the embodiment of the present invention, the limit pull head 14 is arranged obliquely; in this arrangement, the obliquely arranged limit pull head 14 plays a good avoidance role, and facilitates the mutual hooking with the inclined flange on the housing 6.

[0066] Furthermore, in the embodiment of the present invention, the elastic mechanism includes a spring 10, which is sleeved on the pin 9; one end of the spring 10 is connected to the sheet metal buckle, and the other end is connected to the pin 9; the setting of the spring 10, through its own elasticity, makes the pin 9 always have a tendency to move toward the vehicle body 16, so that it can always apply an extrusion force to the shell 6 during subsequent use, thereby ensuring the stability of the installation of the shell 6 on the vehicle body 16; it is also convenient for the subsequent pin 9 to adaptively realize the installation limit of the lamp.

[0067] Furthermore, in the embodiment of the present invention, the fixing mechanism 7 also includes a metal spring 25, which is provided with a through hole. The metal spring 25 is sleeved on the bayonet 9 through the through hole. The metal spring 25 plays a good limiting role and can limit the position of the spring 10, thereby facilitating the connection between the spring 10 and the bayonet 9; at the same time, the setting of the through hole facilitates the installation and sleeve connection of the metal spring 25 on the bayonet 9; in addition, in the embodiment of the present invention, the metal spring 25 is arranged in the assembly through hole 15; the outer circle of the metal spring 25 is in contact with the assembly through hole 15, and such a setting can guide the movement of the metal spring 25 to prevent the metal spring 25 and the bayonet 9 from tilting during movement.

[0068] In addition, in the embodiment of the present invention, the assembly through hole 15 is a stepped through hole; a step is formed in the assembly through hole 15; specifically, in the embodiment of the present invention, the assembly through hole 15 includes a first through hole and a second through hole; the inner diameter of the second through hole is larger than the inner diameter of the first through hole; the first through hole is arranged close to one side of the shell 6, and the second through hole is arranged close to the body 16. Based on such a setting, the above-mentioned step is formed at the connection between the first through hole and the second through hole. The setting of the step plays a good limiting role, which is convenient for limiting the installation position of the spring 10; at the same time, in the embodiment of the present invention, one end of the spring 10 in the elastic mechanism is pressed against the metal spring 25, and the other end is pressed against the step of the assembly through hole 15; based on such a setting, the two ends of the spring 10 do not need to be directly connected to the sheet metal buckle 8 or the pin 9; the difficulty of installing the spring 10 is reduced.

[0069] Furthermore, in the embodiment of the present invention, a limiting component is provided between the metal spring 25 and the bayonet 9; the provision of the limiting component in the embodiment of the present invention plays a good limiting role, ensures the stability of the installation of the metal spring 25 on the bayonet 9, and avoids the movement of the metal spring 25 on the bayonet 9.

[0070] At the same time, in the embodiment of the present invention, the limiting component includes a locking groove 20 arranged on the pin body 19, and the metal spring piece 25 is provided with a locking flange 18, and the locking flange 18 is distributed at the edge of the through hole. The metal spring piece 25 is locked in the locking groove 20 on the pin body 19 through the locking flange 18; based on the above design, the embodiment of the present invention facilitates the installation of the metal spring piece 25 on the pin 9 and avoids the movement of the metal spring piece 25 on the pin 9.

[0071] Furthermore, in the embodiment of the present invention, the fixing mechanism 7 also includes a sealing gasket 11, which is sleeved on the sheet metal buckle 8; the sealing gasket 11 plays a good sealing role. When used subsequently, the sealing gasket 11 is mainly used to seal the gap between the sheet metal buckle 8 and the vehicle body, thereby ensuring the sealing of the connection between the taillight buckle assembly 2 and the vehicle body 16.

[0072] In addition, in the embodiment of the present invention, the sheet metal buckle 8 includes a buckle body 17, which is the main structure of the sheet metal buckle 8. In the embodiment of the present invention, the buckle body 17 includes a buckle body 21 and a buckle end plate 22. Based on such a setting, the buckle body 17 forms a T-shaped structure, the buckle body 21 is inserted into the hole of the vehicle body 16, and the buckle end plate 22 plays a limiting role, which is used to control the excessive insertion of the sheet metal buckle 8 on the vehicle body 16.

[0073] At the same time, in the embodiment of the present invention, a limiting protrusion 13 is provided on the side of the buckle body 21; the limiting protrusion 13 acts as a hook structure to prevent the sheet metal buckle from being separated from the hole of the vehicle body 16.

[0074] At the same time, in the embodiment of the present invention, the limiting protrusion 13 and the buckle end plate 22 are spaced apart; a positioning groove is formed between the limiting protrusion 13 and the buckle end plate 22; the setting of the positioning groove facilitates the installation and limiting of the sealing gasket 11 between the vehicle body 16 and the sheet metal buckle 8.

[0075] The lamp is connected to the vehicle body 16 via the fixing mechanism 7 of the above structure; based on such a setting, the adaptive installation and fixing between the lamp and the vehicle body 16 is facilitated.

[0076] During assembly, the bayonet pin 9 passes through the assembly through hole 15 of the sheet metal buckle 8; the spring 10 is passed through the bayonet pin 9 and is positioned between the metal spring piece 12 and the sheet metal buckle 8; the metal spring piece 12 is stuck on the bayonet pin body 19 of the bayonet pin 9 to limit the spring 10 from falling off; the sealing gasket 11 is then put on the sheet metal buckle 8 and is positioned between the sheet metal bayonet and the vehicle body 16 to play a sealing role and prevent water from seeping in.

[0077] The embodiment of the present invention, based on the above-mentioned structural arrangement, can improve the problem that the original fixed clip is non-adjustable.

[0078] When the fixing mechanism 7 is stuck on the vehicle body 16 and the lamp is installed, when the distance between the shell 6 and the vehicle body 16 is relatively small, due to the setting of the spring 10, the spring 10 can drive the latch 9 to move in one direction, that is, the spring 10 is compressed and stressed inside, exerting a pulling force on the lamp, so that the lamp will not loosen after installation.

[0079] The embodiment of the present invention further provides a vehicle, comprising the lamp of the above structure. Since the vehicle of the embodiment of the present invention comprises the lamp of the above embodiment, it has all the advantages of the above lamp.

[0080] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
