Description

一种多功能复用的汽车照明装置及其照明方法A kind of multi-functional multiplexing automobile lighting device and its lighting method

技术领域technical field

本发明涉及车灯领域，具体的，本发明涉及一种具有复用功能的汽车照明装置及其照明方法，所述汽车照明装置及其照明方法可装配各种照明用具(灯泡)，可形成各种不同的照明功能。The present invention relates to the field of vehicle lamps. Specifically, the present invention relates to a car lighting device and its lighting method with multiplexing functions. The car lighting device and its lighting method can be assembled with various lighting appliances (bulbs) different lighting functions.

背景技术Background technique

随着汽车产业的高速发展，对机动车辆照明设备提出更高的要求，包括：With the rapid development of the automobile industry, higher requirements are placed on motor vehicle lighting equipment, including:

1.在同一发光区域内完成不同功能、不同光照强度及光色的车灯照明，以求达到点灯效果的动态变换效果，同时，实现一个基本上均匀同质的光射出面；1. Car lighting with different functions, different light intensities and light colors is completed in the same light-emitting area, in order to achieve the dynamic transformation effect of the lighting effect, and at the same time, realize a basically uniform and homogeneous light exit surface;

2.由于机动车辆照明设备安装部位的多样性，要求在较小的形状不一的空间内达到上述效果，由此满足新型车灯的设计要求，不影响造型外观，提高车辆照明装置设计的灵活性；2. Due to the diversity of installation parts of motor vehicle lighting equipment, it is required to achieve the above effects in a small space with different shapes, thereby meeting the design requirements of new car lights, without affecting the appearance of the vehicle, and improving the flexibility of vehicle lighting device design sex;

3.用于不同照明功能的照明用具设置不同的单色光源以实现不同的照明功能；3. Lighting fixtures used for different lighting functions are equipped with different monochromatic light sources to achieve different lighting functions;

4.上述汽车照明装置除具有下述光学功能：白色的DRL或PL第一功能，黄色的转向灯第二功能之外，还包括其他颜色的车用第三种功能。4. The above-mentioned automotive lighting device has the following optical functions: the first function of white DRL or PL, the second function of yellow turn signal, and the third function of other colors for vehicles.

现有机动车辆照明设备在用于不同照明功能的照明用具设计时需要考虑彼此相邻位置要求，即需要在照明设备中设计相当大的空间来安装这些具有不同功能的照明用具，通常需要所述各个照明用具形成矩阵排列。The existing motor vehicle lighting equipment needs to consider the requirements of adjacent positions when designing lighting appliances with different lighting functions, that is, it needs to design a considerable space in the lighting equipment to install these lighting appliances with different functions. The individual lighting fixtures form a matrix arrangement.

但是，所述各个照明用具的矩阵排列需要较大的空间，由此需要照明用具在设计时必须加大安装尺寸，以满足两个以上的照明功能要求。However, the matrix arrangement of the various lighting appliances requires a relatively large space, so that the installation size of the lighting appliances must be increased during design to meet the requirements of more than two lighting functions.

例如，德国海拉车灯有限公司(HELLA KGAA HUECK&CO)的发明专利“Lightingdevice for a motor vehicle”(申请号：EP20080163803申请日：2008.09.05)提供了一种具有不同功能的车灯照明装置，所述发明公开的权利要求1的技术方案包括如下特征：For example, the invention patent "Lightingdevice for a motor vehicle" (application number: EP20080163803 filing date: 2008.09.05) of HELLA KGAA HUECK&CO provides a vehicle lighting device with different functions. The technical solution of claim 1 disclosed in the invention includes the following features:

“①对应多项光功能的多组光源(1a,1b,1c)；"① Multiple groups of light sources (1a, 1b, 1c) corresponding to multiple light functions;

②与多组光源耦合(1a,1b,1c)的光导，并且该光导具有至少一个可实现多功能的共同出光体；② A light guide coupled with multiple groups of light sources (1a, 1b, 1c), and the light guide has at least one common light outlet that can realize multiple functions;

③多组光源共用一个载体；③Multiple groups of light sources share one carrier;

④第一光源的功能体现为日行灯和/或位置灯，第二光源的功能体现为转向闪光灯；④ The function of the first light source is reflected in the daytime running lights and/or position lights, and the function of the second light source is reflected in the turning flashlight;

⑤白光LED(1a)和琥珀光LED(1b)置于光源载体上。”⑤ The white light LED (1a) and the amber light LED (1b) are placed on the light source carrier. "

然而，该专利技术方案存在的问题是：Yet the problem that this patent technical scheme exists is:

所述车灯照明装置无法从不同方向，即任何角度引入多组光源的入射光线，这使得在作车灯光学及结构设计时难以作更灵活的空间布置，例如，因光学原理局限，光源只能由后方入射，前方出射，或光导采用光导管形式，由此，使得LED的间距不便调节(在进行普通形式布置，如LED光源从后方入射安排时，由于光学结构的原因，LED间距一般较大，但LED间距大会造成点灯外观不良。在此情况下，需要一种能使得LED间距减小的方案，提高点灯均匀性)，妨碍提高外观均匀性；同时，不便该照明装置各种内部结构布置及有效利用空间；The car light lighting device cannot introduce the incident light of multiple groups of light sources from different directions, that is, from any angle, which makes it difficult to make more flexible spatial arrangements in the optical and structural design of car lights. For example, due to the limitation of optical principles, the light source only It can be incident from the rear, exit from the front, or the light guide adopts the form of a light guide, thus making it inconvenient to adjust the spacing of the LEDs (due to the optical structure, when the LED light source is incident from the rear, the spacing of the LEDs is generally relatively small. Large, but the large LED spacing causes poor lighting appearance. In this case, a solution that can reduce the LED spacing is needed to improve lighting uniformity), which hinders the improvement of appearance uniformity; at the same time, it is inconvenient for various internal structures of the lighting device layout and efficient use of space;

光学层次感较差，难以满足多种不同的造型方案；Poor optical layering, difficult to meet a variety of different modeling solutions;

光导难以与尾灯造型开口紧密贴合，影响造型外观。It is difficult for the light guide to fit closely with the opening of the taillight shape, which affects the appearance of the shape.

又如，“DE 100 43 660 A1”的德国发明专利公开了一种机动车辆的照明装置，所述照明装置使用一个光源载体，用于装配各种车辆照明用具，且共用一个灯体，其中包括两个不同颜色灯光的LED排列成一个灯光总成矩阵，所述灯光总成矩阵设置于一个反光镜或者散射镜后。As another example, the German invention patent "DE 100 43 660 A1" discloses a lighting device for motor vehicles. The lighting device uses a light source carrier for assembling various vehicle lighting appliances, and shares a lamp body, which includes Two LEDs of different colors are arranged to form a light assembly matrix, and the light assembly matrix is arranged behind a reflector or a diffuser.

又如，公开号为“CN106016127A”、上海小糸车灯有限公司的“一种具有不同功能的车灯照明装置”的发明专利，采用两种不同光色的LED光源，配置在厚壁透明光导的一侧,最终通过厚壁透明光导的共同出光体出光，实现两种不同功能；并且LED光源分别单独安装不同的线路板，配置在厚壁透明光导一侧，以将所述两种不同光色的LED光源的入射光线从不同方向引入厚壁透明光导。Another example is the invention patent of "a car light lighting device with different functions" with the publication number "CN106016127A" of Shanghai Koito Auto Lamp Co., Ltd., which uses two kinds of LED light sources with different light colors and is arranged in a thick-walled transparent light guide. On one side, the light is finally emitted through the common light-emitting body of the thick-walled transparent light guide to realize two different functions; and the LED light sources are separately installed on different circuit boards, and are arranged on one side of the thick-walled transparent light guide to combine the two different light colors. The incident light of the LED light source is introduced into the thick-walled transparent light guide from different directions.

US8764257的美国专利涉及一种车辆照明装置，该装置包括实现两种光功能的两个光源，以及将两个光源的光传输到出光体的主光导，这两个光源，一个可以是执行车辆前照灯功能的白光，另一个可以是执行车辆转向灯功能的黄光。The U.S. patent of US8764257 relates to a vehicle lighting device, which includes two light sources to realize two light functions, and a main light guide that transmits the light of the two light sources to the light output body. A white light that functions as a headlight, and another that can be a yellow light that performs the function of the vehicle's turn signal.

该专利的权利要求8进一步揭示了采用主光导和两个辅助光导的技术方案，使主光导有两个辅助分叉，这样两个光源的光分别从辅助分叉进入主光导，在权利要求10中将这种光导结构进一步限定为Y型结构，即将主光导和辅助分叉整体设计成Y型，入光口设计在Y的上部，出光口设计为Y的足部。Claim 8 of this patent further discloses the technical solution of using the main light guide and two auxiliary light guides, so that the main light guide has two auxiliary forks, so that the light of the two light sources enters the main light guide from the auxiliary forks respectively. In claim 10 This light guide structure is further defined as a Y-shaped structure, that is, the main light guide and the auxiliary bifurcation are designed as a Y-shape as a whole, the light entrance is designed on the upper part of the Y, and the light exit is designed as the foot of the Y.

然而，上述现有的技术方案分别程度不同地存在下述问题：However, the above-mentioned existing technical solutions have the following problems to varying degrees:

用于不同照明功能的照明用具需设置不同的单色光源以实现不同的照明功能；Lighting fixtures used for different lighting functions need to be equipped with different monochromatic light sources to achieve different lighting functions;

将两套点灯设备拼装在一个车灯装置的空间中，这就需要一个较大的车灯装置空间来设计安装这些照明用具；或Assembling two sets of lighting equipment in the space of a car light device requires a larger car light device space to design and install these lighting appliances; or

分开排列的点灯设备难以均匀分布在同一发光面，为此因无法满足新型车灯的设计要求；或It is difficult for separately arranged lighting devices to be evenly distributed on the same light-emitting surface, because it cannot meet the design requirements of new-type vehicle lights; or

因用于不同照明功能的照明用具在设计布置时需彼此相邻，这样在照明设备中须考虑设计相当大的车灯照明装置空间来安装这些照明用具。例如，在各个照明用具的排列需要较大空间的场合，须对照明灯具整体结构作加长设计，以满足不同的照明功能要求；或Because the lighting fixtures used for different lighting functions need to be adjacent to each other when designing and arranging, it is necessary to consider designing a considerable space for the lighting device of the car lamps to install these lighting fixtures in the lighting equipment. For example, where the arrangement of various lighting fixtures requires a large space, the overall structure of the lighting fixtures must be designed to be lengthened to meet different lighting function requirements; or

因各个照明用具常作为单个灯光源使用，但各种新型车灯照明装置的发光体具有不同结构、形状及发光位置的发光面，例如，所述发光面常形成矩阵式排列，往往导致在以往的照明装置内无法实现一个基本上均匀同质的光射出面；Because each lighting appliance is often used as a single light source, but the illuminants of various new car lighting devices have light-emitting surfaces with different structures, shapes and light-emitting positions. For example, the light-emitting surfaces are often arranged in a matrix, which often leads to It is impossible to achieve a substantially uniform and homogeneous light exit surface in the lighting device;

或or

除具有白色的DRL或PL第一功能和黄色的转向灯第二功能之外，难以实现包括其他颜色的车用第三种功能。In addition to having the first function of DRL or PL in white and the second function of turn signal in yellow, it is difficult to realize the third function for vehicles including other colors.

发明内容Contents of the invention

为克服上述问题，本发明目的在于：提供一种新型机动车辆照明装置及其照明方法，所述新型机动车辆照明装置及其照明方法通过安装单色光源就能够实现不同的照明功能，且只需很小的安装空间，可以提高灯具空间利用率。In order to overcome the above problems, the object of the present invention is to provide a novel motor vehicle lighting device and its lighting method, which can realize different lighting functions by installing a monochromatic light source, and only need Small installation space can improve the space utilization of lamps.

根据本发明，将不同光色的光源分别布置在一个光传播介质的一端或两端，以共用发光介质实现发光面的均匀效果，节省空间的同时也能满足良好的共用发光面的点灯效果。According to the present invention, light sources of different light colors are respectively arranged at one or both ends of a light propagation medium, and the uniform effect of the light-emitting surface is achieved by sharing the light-emitting medium, which saves space and satisfies a good lighting effect of the shared light-emitting surface.

根据本发明，可以满足新型车灯的设计要求，不影响造型外观，提高车辆照明装置设计的灵活性。According to the invention, the design requirements of the new type of vehicle lamp can be met, the styling and appearance are not affected, and the flexibility of the design of the vehicle lighting device is improved.

根据本发明，可以在一个导光体上实现多种功能，包括具有至少两种不同色度要求的光学功能，典型的是，第一功能为白色光学的DRL或者PL，第二功能为黄色光线的转向灯，还可实现其他颜色的车用第三种功能。According to the present invention, multiple functions can be realized on one light guide, including optical functions with at least two different chromaticity requirements, typically, the first function is DRL or PL of white optics, and the second function is yellow light The turning signal lamp can also realize the third function for vehicles of other colors.

具体实施方式Detailed ways

下面结合附图对本发明作进一步详细的说明。The present invention will be described in further detail below in conjunction with the accompanying drawings.

实施例1Example 1

如图1所示，本实施例的一种多功能复用的汽车照明装置，包括光源(1)、导光体(2)、与导光体(2)连接的辅助导光体(2a)、出光区域(3)以及光源载体(4)等。As shown in Fig. 1, a kind of multi-functional and multiplexed automotive lighting device of the present embodiment comprises a light source (1), a light guide (2), and an auxiliary light guide (2a) connected to the light guide (2) , a light emitting area (3) and a light source carrier (4) and the like.

导光体(2)为透明色，其在头部(或一端)分叉出至少两个端部，辅助导光体(2a)通过双色注塑与导光体(2)一分叉端连接，辅助导光体(2a)为黄色，与导光体(2)的颜色不同，用来实现光色的转换；光源(1)为单色光源，通常可以采用发光二级光(LED)，颜色为白色，其排列在导光体(2)，(2a)后入射端，且可整体安装在光源载体(4)上，也可以分开安装在光源载体(4a)、(4b)上；光源(1)的出射光可控地分别从各分叉端分别射入导光体(2)、(2a)。出射导光体(2)的颜色仍为白色，出射(2a)的颜色变换为近于(2a)的颜色。The light guide body (2) is transparent, and at least two ends are bifurcated at the head (or one end), and the auxiliary light guide body (2a) is connected to a bifurcated end of the light guide body (2) by two-color injection molding, The auxiliary light guide body (2a) is yellow, which is different from the color of the light guide body (2), and is used to realize the conversion of light color; the light source (1) is a monochromatic light source, which can usually use a light-emitting secondary light (LED). It is white, and it is arranged on the light guide body (2), (2a) at the rear incident end, and can be installed on the light source carrier (4) as a whole, and can also be installed separately on the light source carrier (4a), (4b); the light source ( The outgoing light of 1) is controllable to enter the light guide bodies (2) and (2a) respectively from the bifurcated ends. The color of the outgoing light guide (2) is still white, and the color of the outgoing (2a) is transformed into a color close to that of (2a).

该二出射光也可控地分别从各分叉端分别射入导光体(2)、(2a)后，在导光体(2)耦合，最后通过出光区域(3)将入射光线射出，实现不同色度要求的不同光学功能。The two outgoing lights are also controllable to enter the light guide body (2) and (2a) respectively from each bifurcated end, and then couple in the light guide body (2), and finally emit the incident light through the light exit area (3), Realize different optical functions with different chromaticity requirements.

例如，光源(1)的白色出射光可控地仅经过导光体(2)后任为白色，实现需要白色光色的第一功能DRL或者PL。For example, the white emitted light from the light source (1) can be controlled to pass only through the light guide (2) and then become white, so as to realize the first function DRL or PL that requires white light color.

如光源(1)的白色出射光可控地仅经过导光体(2a)时，因辅助导光体(2a) 为黄色，出射光也变为黄色，进入导光体(2)后通过出光区域(3)射出，实现需要黄色光色的第二功能的转向灯功能。For example, when the white outgoing light of the light source (1) only passes through the light guide body (2a) in a controllable manner, because the auxiliary light guide body (2a) is yellow, the outgoing light also turns yellow, and passes through the outgoing light after entering the light guide body (2). Area (3) shoots out, realizes the turn signal function that needs the second function of yellow light color.

实施例2Example 2

如图2所示，光源(1)分开安装在不同的光源载体(4a)、(4b)上，其光线的入射方向可以根据采用的光学方式的不同而更改，保证将入射光射入导光体(2)。图2中，入射光方向为与分叉端延长线垂直的方向，则光线进入导光体(2)及辅助导光体(2a)后方向与导光体方向垂直，此时，通过在导光体内部增加聚光器或反射壁等方式来改变入射光线方向，使得光线沿着导光体方向射入。本实施例主要针对导光体头部在灯具内安装空间不足的情况下采用。As shown in Figure 2, the light source (1) is installed separately on different light source carriers (4a), (4b), and the incident direction of the light can be changed according to the optical method used to ensure that the incident light is injected into the light guide body (2). In Fig. 2, the direction of incident light is the direction perpendicular to the extension line of the bifurcation end, then the light enters the light guide body (2) and the auxiliary light guide body (2a) and the direction is perpendicular to the direction of the light guide body.
