Description

Technical Field

[0001] The utility model relates to a lighting structure, more specifically, it relates to a vehicle lamp. Background Art

[0002] The lights of vehicles are mandatory to have high beam and low beam according to regulatory requirements. High beam or low beam is one of the main functions of vehicle headlights, generally used to illuminate the road ahead. Secondary functions include daytime running lights or direction indicators, which perform the function of signal devices designed to send light signals to other road users.

[0003] There are two design forms for low beam and high beam lighting units: 1. The low beam and high beam are integrated in one lighting unit. 2. The low beam and high beam are split. However, regardless of whether the low beam and high beam are integrated in one lighting unit or separated in two lighting units, when the low beam and high beam are lit at the same time, the brightness of the high beam will decrease. Therefore, the low beam is a constant light function at night, while the high beam is not often lit. When the low beam lighting unit is lit, the appearance of the high beam lighting unit is lightless. The disadvantage of this setting is that the high beam lighting unit is in the off state, which will cause a visual sense of emptiness, resulting in a significant reduction in the beauty of the vehicle lights and a decline in the competitiveness of the product. If an additional circuit board and additional optical components are added to realize the common lighting of the high beam lens of the high beam lighting unit and the low beam lighting unit under low beam working conditions, the use cost of the product will increase. Secondly, the low beam lighting unit or the high beam lighting unit often adopts a segmented lens design. When the low beam lighting unit is lit, each lens segment area is in a lit state. At the same time, in order to make the overall appearance of the headlight present a good lighting effect, the high beam lighting unit must also be able to light up at the same time. If the light emitted by the light source is very easily converged by the lens and forms a high-brightness light spot, it will cause the low beam light pattern to be super bright, which does not meet the low beam regulations.

[0004] In the prior art, the low beam lens module and the high beam lens module are integrated. Integrated means that the light source is integrated, multiple light sources are packaged as one, or the reflective bowl or inner lens used to reflect the low beam / high beam / auxiliary light is integrated, or the outer lens that projects the low beam / high beam / auxiliary light to the front of the car is together. The problem with this is that the structural design needs to be comprehensively considered during the light distribution optical design, and the flexibility of the arrangement and combination of the low beam lens module and the high beam lens module cannot be increased.

[0005] The existing auxiliary light needs to be equipped with a lens module separately, which has a technical problem that the internal space utilization rate of the headlight is not high and is not conducive to the miniaturization design of the headlight.

[0006] In summary, the present application aims to provide a vehicle lamp that can optimize the problems of high coupling degree and poor flexibility brought about by the existing integrated module, as well as crowded internal space and difficulty in miniaturization caused by the provision of auxiliary light. Summary of the invention

[0007] The utility model overcomes various deficiencies brought by the existing integrated module and provides a vehicle lamp which can optimize the problems brought by the existing integrated module, such as high coupling degree, poor flexibility, crowded internal space caused by setting auxiliary light, and difficulty in miniaturization.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A vehicle lamp comprises a plurality of lens modules with independent light paths and lampshades arranged on the lens modules, wherein the lens modules comprise a low beam lens module and a high beam lens module, and the lens modules are fixedly arranged along a preset arrangement.

[0010] These modules can realize different functions of car lights, such as low beam, daytime running light and high beam. At the same time, the high beam lens module integrates the functions of high beam and daytime running light, so no additional space is needed to install the daytime running light, saving the installation space in the car lights, and at the same time, different numbers of lens modules can be flexibly placed to provide multiple lighting modes.

[0011] The vehicle lamp of the present application realizes a multifunctional, space-saving and flexible design. Each low beam lens module or high beam lens module is regarded as a unit, and these units are arranged in various and flexible combinations, and can be arranged in various vehicle platforms, saving R&D costs.

[0012] Preferably, the low beam lens module includes a reflective bowl, an LED light source, a light pattern baffle detachably connected to the reflective bowl, a PCB board, a heat sink and an outer lens. The LED light source is arranged on the PCB board. The reflective bowl and the LED light source are located on the same side of the PCB board and part of the bowl edge of the reflective bowl is attached to the PCB board. The reflective bowl reflects and converges the light generated by the LED light source and then emits it from the outer lens through the shielding of the light pattern baffle. The PCB board is attached to a heat sink on the side away from the reflective bowl. The low beam lens module uses an LED lamp as a light source, which is reflected by the reflective bowl and emitted to the outer lens to form a light path. In order to meet the low beam cutoff line required by regulations, a low beam light pattern formed by the reflection of the low beam reflective bowl is shielded and corrected, similar to a semi-elliptical low beam light pattern. The low beam light patterns generated by multiple low beam lens modules overlap to form a perfect low beam light pattern without any extra light spots. The PCB board not only provides energy supply and control circuits for the LED lamp, but also plays a supporting and heat transfer role, transferring heat to the heat sink on the back. The heat sink is used to transfer the heat generated by the circuit-lamp to the outside to avoid heat accumulation, which will cause the high temperature of the lens module and affect its life and light-emitting effect.

[0013] Preferably, a protruding skirt is provided at the highest point of the edge of the reflective bowl, and the protruding skirt reflects part of the light emitted to the outside of the reflective bowl and directed toward the LED light source to the outward lens. Since the LED light source is a plane 180-degree divergent light, and the reflective bowl structure is a semi-enclosed type, there is a small part of the light that is divergent from a large angle. The protruding skirt can reuse this small part of the light to improve efficiency.

[0014] Preferably, the reflective bowl includes a connecting structure and a reflective bowl body, the connecting structure includes a plate body, a handle body and a clamping hole, the plate body and part of the bowl edge of the reflective bowl body are connected and coplanar, the clamping hole is arranged on both sides of the plate body and is symmetrically arranged relative to the reflective bowl body, and a guide column is also fixedly connected to the side of the plate body facing the radiator, corresponding positioning holes and buckles adapted to the buckle holes are provided on the light-shaped baffle, and the light-shaped baffle blocks part of the light path to cooperate with the outer lens to form the cut-off line required for the low beam.

[0015] Preferably, the handle body is arranged at the outer edge of the plate body, one end of the handle body is connected to the plate body, and the other end is provided with a handle suitable for grasping by a robot, the upper side of the handle is flat and the lower side is protruding outwards. The shape of the handle is conducive to grasping by a robot.

[0016] Preferably, the high-beam lens module includes a reflective bowl, an LED light source group, a PCB board, a heat sink and an outer lens. The LED light source group is arranged on the PCB board. The LED light source group includes a high-beam LED light source arranged at the modeling focus position of the reflective bowl and an auxiliary LED light source arranged outside the modeling focus. The reflective bowl and the LED light source group are located on the same side of the PCB board and part of the bowl edge of the reflective bowl is attached to the PCB board. The reflective bowl reflects and converges the light generated by one or more of the LED light sources and then emits it from the outer lens through the shielding of the light-shaped baffle. The PCB board is attached with a heat sink on one side away from the reflective bowl. On a plane perpendicular to the PCB board, the auxiliary LED light source is located in the projection of the reflective bowl. The high-beam LED light source and the auxiliary LED light source located at the focus play the functions of high beam and daytime running light, thereby eliminating the lens module corresponding to the daytime running light, thereby saving space.

[0017] Preferably, the radiator has radiating fins, which are perpendicular to the PCB board, and the closer the radiator is to the lampshade, the shorter the radiating fins are. The length of the radiating fins is adapted to the size of the lampshade, so that the module is compact.

[0018] Preferably, a protrusion is provided on the edge of the reflective bowl, and the protrusion fits the PCB board so that a gap for heat dissipation is provided between the reflective bowl and the PCB board. The structure prevents heat from accumulating inside the reflective bowl, which causes high-temperature aging of the reflective bowl.

[0019] Preferably, the preset arrangement is along a single straight line or a combination of multiple straight lines, in a single row or multiple rows.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] (1) Each low beam lens module or high beam lens module is regarded as a unit. These units can be arranged in various and flexible combinations and can be arranged in various vehicle platforms;

[0037] Example:

[0038] A vehicle lamp comprises a plurality of lens modules with independent optical paths and a lampshade 7 arranged on the lens modules, wherein the lens modules comprise a low beam lens module 91 and a high beam lens module 92. In the present embodiment, the low beam lens module 91 and the high beam lens module 92 have the same size, and in some other embodiments, the low beam lens module 91 and the high beam lens module 92 may be different in size, and the lens modules are fixedly arranged along a preset arrangement.

[0039] These modules can realize different functions of the headlights, such as low beam, daytime running light and high beam. At the same time, the high beam lens module 92 integrates the functions of the high beam and the daytime running light, so no additional space is needed to install the daytime running light, saving the installation space in the headlight, and at the same time, different numbers of lens modules can be flexibly placed to provide multiple lighting modes.

[0040] The vehicle lamp of the present application realizes a multifunctional, space-saving and flexible design. Each low beam lens module 91 or high beam lens module 92 is regarded as a unit, and these units are arranged and combined in various and flexible ways, and can be arranged in various vehicle platforms, saving R&D costs.

[0041] The low beam lens module 91 includes a reflective bowl 1, an LED light source, a light-shaped baffle 4 detachably connected to the reflective bowl 1, a PCB board 2, a heat sink 5 and an outer lens 6. The LED light source is arranged on the PCB board 2. The reflective bowl 1 and the LED light source are located on the same side of the PCB board 2 and part of the bowl edge of the reflective bowl 1 is in contact with the PCB board 2. The reflective bowl 1 reflects and converges the light generated by the LED light source and then emits it from the outer lens 6 through the obstruction of the light-shaped baffle 4. The PCB board 2 is in contact with the heat sink 5 on the side away from the reflective bowl 1.

[0042] Ginseng Figure 1 , 2 As shown, the reflective bowl 1 includes a connecting structure 10 and a reflective bowl body 20, the connecting structure 10 includes a plate body 11, a handle body and a clamping hole 112, the plate body 11 and the reflective bowl body 20 are partially connected and coplanar, the clamping hole 112 is arranged on both sides of the plate body 11 and is symmetrically arranged relative to the reflective bowl body 20, and the side of the plate body 11 facing the radiator 5 is also fixedly connected with a guide column 111, and the light-shaped baffle 4 is provided with corresponding positioning holes 42 and buckles 41 adapted to the buckle holes, and the light-shaped baffle 4 blocks part of the light path to cooperate with the outer lens 6 to form a cut-off line required for the low beam.

[0043] The reflective bowl body 20 is a quarter hollow ellipsoid, and specifically, the reflective bowl body 20 is a curved surface formed by tangent of two planes through a sphere. In some embodiments, the two planes are perpendicular, and the bowl edge of the reflective bowl body 20 is obtained by tangent of the dormitory plane.

[0044] At least part of the edges of the plate body 11 and the reflective bowl body 20 are coplanar and connected. The plate body 11 is a sheet-like or thin structure, and its shape is a rectangle with an arc-shaped notch, wherein the arc-shaped notch is adapted to the contour of the reflective bowl body 20 and the plate body 11. The width of the plate body 11 should be slightly larger than the arc-shaped notch. In this embodiment, the plate body 11 coincides with any one of the aforementioned planes, and the structure can enhance the rigidity of the reflective bowl body 20, and can also avoid stress concentration, protect the reflective bowl body 20 during use, and avoid damage to its edges. The handle body is used for gripping by a robot.

[0045] The handle is arranged at the outer edge of the plate 11, one end of the handle is connected to the plate 11, and the other end is provided with a handle suitable for grasping by a robot, the upper side of the handle is flat and the lower side is convex outward. The shape of the handle is conducive to grasping by a robot.

[0046] The handle body includes a rod body 121 and a handle body. One end of the rod body 121 is connected to the plate body 11, and the other end is connected to a handle body suitable for grasping by a robot. The handle body is a flange turned out by the rod body 121. The handle body is a thin sheet. In some preferred embodiments, the shape is rectangular. In some embodiments, the handle body and the rod body 121 are of equal thickness. In other embodiments, the handle body is flat on the top and convex on the bottom. In still other embodiments, the handle body is concave on the top and bottom. Among them, the direction of the rod body 121 is perpendicular to the direction of the plate body 11, and the flange is turned out in a direction away from the reflector body 20.

[0047] In some embodiments, the connection structure 10 includes a handle body, and the handle body is connected to the curved surface of the outer side of the reflector body 20 .

[0048] The bowl edge of the reflective bowl body 20 is provided with a protrusion 22, which fits with the PCB board 2 so that a gap for heat dissipation is provided between the reflective bowl 1 and the PCB board 2. The structure prevents heat from accumulating inside the reflective bowl 1, causing the reflective bowl 1 to age at high temperature.

[0049] A protruding skirt 21 is provided at the highest point of the edge of the reflective bowl 1, and the protruding skirt 21 reflects part of the light emitted from the LED light source to the outside of the reflective bowl 1 to the outer lens 6. Since the LED light source is a plane 180-degree divergent light, and the reflective bowl 1 is a semi-enclosed structure, a small part of the light is diverged from a large angle, and the protruding skirt 21 can reuse this small part of the light to improve efficiency.

[0050] In addition to the guide column 111, the plate body 11 also has a connecting column 113, which is inserted into the PCB board 2 to position the reflective bowl 1, which is similar to the positioning of the reflective bowl 1 to the light-type baffle 4. The plate body 11 is also fixedly connected to the PCB board 2 by fasteners.

[0051] The radiator 5 has radiating fins, which are perpendicular to the PCB board 2. The closer the radiator 5 is to the lampshade 7, the shorter the radiating fins are. The length of the radiating fins is adapted to the size of the lampshade 7, so that the module is compact.

[0052] The plate 11 is provided with an identification code or foolproof shape for identification by a code reader connected to the robot. The identification code provides the model and identification information of the reflective bowl 1 and provides corresponding size information to facilitate subsequent assembly processing. The foolproof shape refers to the addition of a small structure for identification on the handle structure.

[0053] The low beam lens module 91 uses an LED lamp as a light source, which is reflected by the reflective bowl 1 and directed to the outer lens 6 to form a light path. In order to meet the low beam cutoff line required by regulations, a low beam light pattern formed by the reflection of the low beam reflective bowl 1 is blocked and corrected, similar to a semi-elliptical low beam light pattern. The low beam light patterns generated by multiple low beam lens modules 91 overlap to form a perfect low beam light pattern without any extra light spots. The PCB board 2 not only provides power supply and control circuits for the LED lamp, but also plays a supporting and heat transfer role, transferring heat to the heat sink 5 on the back. The heat sink 5 is used to transfer the heat generated by the circuit-lamp to the outside to avoid heat accumulation, which causes high temperature of the lens module to affect its life and light-forming effect.

[0054] Ginseng Figure 3 As shown, the difference between the high-beam lens module 92 and the low-beam lens module 91 is that the high-beam lens module 92 does not have the light-shaped baffle 4, but the number of LED light sources is multiple, forming an LED light source group, which is arranged on the PCB board 2. The LED light source group includes a high-beam LED light source 81 set at the modeling focus position of the reflective bowl 1 and an auxiliary LED light source 82 set outside the modeling focus. The reflective bowl shared by the high-beam LED light source and the auxiliary LED light source has the same reflective surface. On a plane perpendicular to the PCB board 2, the auxiliary LED light source 82 is located in the projection of the reflective bowl 1. The high-beam LED light source 81 and the auxiliary LED light source 82 located at the focus play the role of high beam and daytime running light, thereby eliminating the lens module corresponding to the daytime running light, thereby saving space.

[0055] The preset arrangement is along a single straight line or a combination of multiple straight lines, in a single row or multiple rows.

[0056] Ginseng Figure 4 As shown, in some embodiments, each lens module is arranged side by side in a single row along a horizontal line direction.

[0057] Ginseng Figure 5 As shown, in other embodiments, each lens module is arranged side by side in a single row along the diagonal direction.

[0058] Ginseng Figure 6 As shown, in some other embodiments, each lens module is arranged in a single row in the direction of a horizontal line and a vertical line.

[0059] In some further embodiments, each lens module is arranged in two or three rows in a straight line direction.

[0060] Ginseng Figure 7 As shown, taking two rows as an example, each row has three lens modules, and each row has a low beam lens module 91 and a high beam lens module 92 .

[0061] The external main control circuit is electrically connected to each lens module respectively, and a switch or other control method is set so that the main control circuit can drive all the lens modules.

[0062] In this way, we can achieve a multifunctional, space-saving and flexible lighting device.
