Description

Vehicle lamp {LAMP FOR A VEHHICLE}

The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp mounted on a vehicle to irradiate light in at least one direction.

A vehicle is a device that moves a user in a desired direction. A typical example is a car.

On the other hand, it is a trend that various sensors and electronic devices are provided in a vehicle for the convenience of a user who uses the vehicle. In particular, research on an Advanced Driver Assistance System (ADAS) is being actively conducted for user convenience. Furthermore, the development of autonomous vehicles (Autonomous Vehicle) is being actively made.

Such a vehicle is provided with various types of lamps for irradiating light or outputting vehicle-related signals to other vehicles, passengers of other vehicles, or pedestrians so that objects located around the vehicle can be easily identified.

For example, a head lamp attached to the front of the vehicle and installed to brightly illuminate the front, a fog lamp disposed around the headlight to inform drivers or pedestrians of the vehicle's location to drive, A turn signal lamp for outputting a signal such as a turn signal. A brake lamp to guide whether the vehicle is being braked, a back-up lamp that is turned on when the vehicle is reversing, and a tail lamp to inform the driver of a subsequent vehicle of the rear of the vehicle can be provided in In order for these vehicle lamps to fully exhibit each function, the installation standards and standards are prescribed by laws and regulations.

A typical rear lamp includes a lens that forms an external shape and transmits light, a light emitting unit generating the light, and a control unit controlling on/off of the light emitting unit. The rear lamp uses a reflector made of an aspherical surface or uses a light guide to create a fixed light distribution pattern.

Although the reflector or light guide allows a person looking at the lamp to intuitively perceive the three-dimensional structure of the lamp, it is difficult to create a three-dimensional light distribution pattern due to the limitation of the light source itself.

Accordingly, research is being conducted to implement a three-dimensional light distribution pattern by changing the light source itself. For example, research on implementing a lamp using a surface light source is being conducted. However, due to the nature of the surface light source, it is difficult to secure the amount of light stipulated by the law, and studies on the structure of a vehicle lamp that can bring about integrated aesthetics and advanced sensibility are still insufficient.

In addition, since a lamp is a device that illuminates a dark place or sends a signal by turning on a light, a vehicle designer can use the lamp to change the cold image of a machine created by the vehicle into a warm image. For example, when a lamp that is turned off is turned on, a visual effect may occur as if the vehicle comes to life.

However, the present invention is not limited to the rear lamp, and may be modified into various lamps provided in a vehicle, such as a head lamp.

Hereinafter, for convenience of explanation, the present invention will be described through an example provided on the right side of the vehicle among the rear lamps provided on both sides of the rear of the vehicle. There is only some difference (left and right inversion) in the installation direction or shape, and the present invention can be applied even when the rear lamp is provided in the left direction of the vehicle 100 and/or is provided alone in the center of the vehicle 100 there is.

8A and 8B are front views of a vehicle lamp according to an embodiment of the present invention as viewed from the front. FIG. 8A illustrates a vehicle lamp in an off state, and FIG. 8B illustrates a vehicle lamp in an on state.

The vehicle lamp 800 according to an embodiment of the present invention includes a frame fixed to a vehicle body and a plurality of surface light sources installed on the frame.

A wiring line for supplying power to the surface light source is connected to the frame, and the frame may be directly fastened to the vehicle body or fixed through a bracket. A transparent lens may be provided in order to more diffuse and sharpen the light emitted by the surface light source.

The planar light source is a concept distinct from a point light source, and means a planar light source having a predetermined size. The surface light source is composed of a plurality of point light sources that simultaneously diffuse light, and the user perceives not each of the point light sources, but a predetermined area in which the point light sources are distributed as one light source.

The surface light source has a surface configured to emit light, and is made to be flexible to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the surface light source. Such a deformable surface light source may be referred to as a 'flexible surface light source'. A flexible surface light source refers to a light and durable surface light source that is manufactured on a thin and flexible substrate that can be bent, bent, folded, twisted or curled like paper while maintaining the characteristics of an existing surface light source.

In a state in which the surface light source is not bent (eg, a state having an infinite radius of curvature, hereinafter referred to as a first state), the surface light source becomes a flat surface. In a state bent by an external force in the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), at least a part of the surface light source may be curved or curved. The surface light source may be switched from the first state to the second state, or may be switched from the second state to the first state.

The pixel of the surface light source may be implemented by a semiconductor light emitting device. In the present invention, a light emitting diode (LED) is exemplified as a type of a semiconductor light emitting device that converts current into light. The light emitting diode is formed in a small size, so that it can serve as a pixel even in the second state.

A plurality of surface light sources are bent or twisted to form a three-dimensional structure, but are arranged to minimize mutual interference. For example, the first surface light source and the second surface light source may be disposed to cross each other at a point, and a part of the second surface light source may be covered by the first surface light source at the one point.

Each surface light source may be formed of a long and thin line having a predetermined width, that is, a strip line. Each surface light source may have a different width and length.

A three-dimensional flame shape can be created by three-dimensionally disposing a plurality of surface light sources intersecting each other. For example, as shown in FIGS. 8A and 8B , when the vehicle lamp 800 is turned off and then turned on, an effect of generating a flame may be generated. As another example, when a plurality of surface light sources are sequentially turned on, a starting effect in which the flame gradually burns and becomes larger may be generated.

Hereinafter, the vehicle lamp 800 implemented using the surface light source will be described in more detail with reference to the drawings.

The vehicle lamp 800 may include a communication unit 810 , a surface light source 830 , a driving unit 850 , and a control unit 880 . However, since the components shown in FIG. 9 are not essential in implementing the vehicle lamp 800, the vehicle lamp 800 described herein has more or fewer components than those listed above. can have

Among the components, the communication unit 810 enables communication between the vehicle lamp 800 and the vehicle 100 or between the vehicle lamp 800 and various components provided in the vehicle 100 . It may include one or more modules that For example, the communication unit 810 may include a module configured to perform CAN (controller are network) communication.

The communication unit 810 may receive information related to driving of the vehicle from various components provided in the vehicle. All information received by the vehicle lamp 800 through the communication unit 810 is referred to as 'vehicle driving information'.

The vehicle driving information may include vehicle information and surrounding information of the vehicle.

The vehicle information means information about the vehicle itself. Vehicle information includes, for example, vehicle traveling speed, traveling direction, acceleration, angular speed, position (GPS), weight, number of passengers in the vehicle, whether brakes are operated, vehicle braking force, maximum braking force of the vehicle, air pressure of each wheel, Centrifugal force applied to the vehicle, the driving mode of the vehicle (whether autonomous driving mode or manual driving), the parking mode of the vehicle (autonomous parking mode, automatic parking mode, manual parking mode), whether a user is in the vehicle, and the user It may include information related to

The surrounding information of the vehicle means information related to other objects located within a predetermined range around the vehicle and information related to the outside of the vehicle. For example, the condition of the road surface (friction force) on which the vehicle is traveling, the weather, the distance to the front (or rear) vehicle, the relative speed of the front (or rear) vehicle, the curvature of the curve when the driving lane is a curve, the vehicle Ambient brightness, information related to an object existing in a reference area (constant area) based on the vehicle, whether an object enters/leaves into the predetermined area, whether a user exists around the vehicle, and information related to the user (e.g. For example, whether the user is an authenticated user), and the like.

In addition, the surrounding information (or surrounding environment information) of the vehicle includes ambient brightness, temperature, sun position, object information (people, other vehicles, signs, etc.) located in the vicinity, the type of road surface being driven, topographical features, lanes ( Line) information, driving lane information, and information necessary for autonomous driving/autonomous parking/autonomous parking/manual parking modes may be included.

The surface light source 830 has one surface configured to emit light. A support portion is connected to the other surface of the surface light source 830 , and the surface light source 830 may be fixed or supported to the frame of the vehicle lamp 800 by the support portion. The support part and the frame may be integrally formed by injection at low temperature sintering.

The support part may be made of graphite manufactured by low-temperature sintering. Graphite produced by low-temperature sintering has excellent thermal conductivity and has the advantage of being able to freely create injection shapes. Not only is it 50% lighter than aluminum, but it is also a material that can reduce costs when mass-produced.

The physical properties of the graphite include a metal additive based on 100% of the carbon content so that the carbon content is less than 90% to 100%. In other words, the support portion may be made of graphite having a carbon content of less than 90% to 100%.

The support unit may serve as a heat sink for the surface light source 830 by transferring heat generated by the surface light source 830 to the frame.

Furthermore, the support portion may be subjected to surface treatment to suppress the fine powder of graphite and to enhance mechanical properties.

The surface light source 830 includes a plurality of surface light sources disposed at different positions. For example, the surface light source 830 may include a first surface light source and a second surface light source that intersects the first surface light source at at least one point.

A three-dimensional shape different from that of an existing lamp may be made by a plurality of surface light sources disposed at different positions. To make the shape more three-dimensional, the plurality of surface light sources may have different shapes.

Meanwhile, the driving unit 850 is connected to the other surface of the surface light source 830 , and applies an external force to the surface light source 830 . The driving unit 850 is driven under the control of the control unit 880 and generates an external force to deform the surface light source 830 .

The controller 880 controls the overall operation of the vehicle lamp 800 . The control unit 880 may provide or process appropriate information or functions to the user by processing signals, data, information, etc. input or output through the above-described components or by driving an application program stored in a memory (not shown). .

In addition, the controller 880 may control at least some of the components included in the vehicle lamp 800 to drive an application program stored in the memory. Furthermore, in order to drive the application program, the controller 880 may operate at least two or more of the components included in the vehicle lamp 800 in combination with each other.

For example, when the brake of the vehicle 100 is operated, the controller 880 controls the surface light source 830 to emit light with a predetermined brightness.

As another example, the controller 880 may control the driving unit 850 to generate a preset external force based on a signal (or vehicle driving information) received from the vehicle.

Hereinafter, the organic operation of the surface light source 830 and the driving unit 850 will be described in detail with reference to the accompanying drawings.

10 is a conceptual diagram for explaining the vehicle lamp of FIG. 9 in more detail, and FIG. 11 is an exploded perspective view for explaining a coupling relationship between a plurality of surface light sources.

Referring to FIG. 10 , the vehicle lamp 800 may include a plurality of surface light sources including a first surface light source 822 and a second surface light source 824 . For convenience of explanation, the present invention will be described using the first and second surface light sources 822 and 824, but the present invention is not limited thereto, and more surface light sources may be included.

Each of the surface light sources is connected to a corresponding support portion, and may be fixed or supported on the frame 870 by the support portion. In addition, each surface light source has a unique shape by twisting, wrinkling, or bending part, and the shape is maintained by the support part.

Meanwhile, the first surface light source 822 and the second surface light source 824 may be formed to cross at least one point. The intersection is for creating a three-dimensional structure by the surface light sources, and may be made in a manner not in contact with each other or in a manner in which they are in contact with each other.

In the case of mutual contact, the first surface light source 822 has a groove S, and the second surface light source 824 is inserted into the groove S to form a first surface light source 822 and made to intersect.

When an external force is applied to any one of the first and second surface light sources 822 and 824, an external force is also applied to the other one through the intersection of the first and second surface light sources 822 and 824, so that the first and second surfaces The light sources 822 and 824 are deformed at the same time.

For example, when the second surface light source 824 moves in the Z-axis direction by an external force applied from the driving unit, the first surface light source 822 is also deformed or moved by the external force applied to the second surface light source 824 . This can be done. The deformation occurring in the first surface light source 822 may vary depending on the characteristics of the external force applied to the second surface light source 824 and the position of the intersection point.

Embodiments in which an external force is applied to the surface light source 830 by the driving unit 850 will be described below with reference to the drawings.

12A, 12B, 13A, and 13B are exemplary views for explaining the operation of the driving unit.

The controller 880 may control the surface light source 830 to change at least one of a color, brightness, and saturation of the light emitted from the surface light source 830 according to a preset condition. Furthermore, the control unit 880 may control the driving unit 850 to vary the external force applied to the surface light source 830 according to the preset condition.

Here, the preset condition may be a condition related to the vehicle driving information. At least one of the degree to which the vehicle 100 is braked by the operation of the brake, the acceleration of the vehicle 100, and the possibility of collision calculated from another vehicle located at the rear of the vehicle 100 may be related to a preset condition. .

For example, if the acceleration due to braking is within the first range, the first light may be generated from the surface light source 830 and the first external force may be generated from the driving unit 850 . On the other hand, if the acceleration due to braking is within the second range, the second light may be generated from the surface light source 830 and a second external force may be generated from the driving unit 850 . The first and second lights mean that at least one of hue, brightness, and saturation is different.

As another example, if the collision possibility is within the first possibility range, a third external force may be generated in the driving unit 850 , and if it is within the second possibility range, a fourth external force may be generated. As the probability of collision increases, the driving unit may be controlled such that a relatively large deformation is made in the surface light source. Since the surface light source operates as a brake light, as the deformation of the surface light source becomes severe, the driver of another vehicle can recognize that the possibility of a collision is high.

Meanwhile, the second surface light source 824 may be connected to at least one support portion 892 and 894 . The at least one support part may include a driving part configured to apply an external force to the second surface light source 824 or may be a driving part itself.

For example, the driver may apply an external force to the second surface light source 824 in one direction. Since the second surface light source 824 has the shape of a strip line, when an external force is applied at one point, the second surface light source 824 is deformed based on the other fixed point. In other words, deformation occurs in the surface light source by the vector between the fixed point and the point to which an external force is applied.

The memory may store preset conditions, positions of support points corresponding to the preset conditions, and characteristics of external force to be applied.

When any one of a plurality of preset conditions is satisfied, the control unit 880 controls the driving unit 850 to apply a predetermined external force to the surface light source 830 . Accordingly, the surface light source 830 corresponding to any one of the conditions is deformed.

A plurality of states may be preset for the second surface light source 824 . When any one of a plurality of preset conditions is satisfied, the control unit 880 controls the driving unit 892-896 to be in a state that meets the condition.

For example, as shown in FIG. 12A , the driving unit may be configured to apply an external force in one direction. In other words, the driving unit may be configured such that a point of the surface light source connected to the driving unit is pushed or pulled in one direction. In this case, the surface light source may move in one direction, be crumpled, or be transformed into a planar state in which the crumple is unfolded.

For another example, as shown in FIG. 12B , the driving unit may be configured to rotate and move a point of the surface light source connected to the driving unit. In this case, the surface light source may be twisted like a twist, or a twisted part may be transformed into a plane.

14A and 14B are conceptual views for explaining a film disposed on a surface light source.

Since the surface light source follows the Lambertian emission pattern, it has a dependence of the cosine function. In particular, referring to FIG. 14 , since the surface light source 822 according to the present invention includes first and second portions 822a and 822b that emit light in different directions due to bending, the surface light source 822 emits light. The luminous efficiency of the resulting light decreases. For this reason, there may be a problem in that the amount of light required by the law is not satisfied.

In order to solve this problem, the surface light source 822 of the vehicle lamp 800 according to the present invention may further include a film 1410 disposed on one surface of the surface light source 822 configured to emit light.

The film 1410 is formed so that different portions of the bent or twisted surface light source 822 emit light in a predetermined range. In other words, the film 1410 is configured to compress light in order to secure the amount of light required by law.

The film 1410 may be disposed on at least a portion of the surface light source 822 . Specifically, the surface light source 822 may be divided into a first portion 822a that faces a direction within a predetermined range with respect to the Z-axis direction, and a second portion 822b that faces a direction other than the predetermined range. The film 1410 may be disposed on the second portion 822b.

The film 1410 is configured to change the path of light emitted from the second portion 822b of the surface light source 822 . For example, the film may be formed of a plurality of thin film layers having a predetermined refractive index. As another example, it may include a plurality of protrusions having a predetermined shape to form a predetermined light distribution pattern, and may be formed of an optical layer made of a light-transmitting material.

Light emitted from the second portion 822b of the surface light source 822 passes through the film 1410 and is directed in a predetermined range based on the Z-axis direction. Accordingly, even through the curved surface light source, the amount of light required by the law can be emitted within the predetermined range.

15A and 15B are conceptual views for explaining a vehicle lamp that classifies one surface light source into a plurality of parts and controls the plurality of parts in different ways.

The first and second surface light sources 822 and 824 are cross-sectional views viewed in the X-axis direction.

One surface of each surface light source may be classified into a plurality of parts. For example, the surface light source may be classified into a plurality of parts based on at least one of distortion, wrinkling, a direction in which the surface faces, a distance from a preset reference line, and an intersection point of the first and second surface light sources.

For example, it may be classified into a flat portion having a curvature equal to or less than the reference curvature and a curved portion having a greater curvature than the reference curvature. Alternatively, it may be classified into a front portion that faces within a predetermined range based on the Z-axis direction, and a side portion that faces outside the predetermined range. Alternatively, it may be classified into a portion outside the reference line and a portion inside the reference line based on a preset reference line. Alternatively, based on the intersection point, it may be classified into a part outside the intersection point and a part inside the intersection point.

This classification may vary depending on the external force applied to the surface light source. This is because deformation occurs in the surface light source by an external force.

The controller controls the surface light source to change at least one of a color, brightness, and saturation of each of the parts. For example, referring to FIG. 15A , the portion HL outside the reference line may be controlled to have a first brightness, and the portion LL inside the reference line may be controlled to have a second brightness. Thereafter, when deformation occurs in the surface light source, as shown in FIG. 15B , the reference line outer portion HL and the reference line inner portion LL may also be different.

Since the plurality of parts are controlled differently, a more three-dimensional visual effect can be generated.
