请参照图1，本发明第一实施例中的车辆前照灯100位于车辆200的前端，不再分左右两个组合大灯，而是包括多个阵列排布于车辆200前端的高亮的LED模组110。在本实施例中，该多个LED模组110的宽度大致等于车辆200前端车头的宽度，但不限于此。可以理解的是，通过合理设置LED模组110的位置及照明方向，可以减少LED模组110的使用数量及宽度。车辆200前方的整个区域分为若干个投射区120，该每个LED模组110照亮车辆200前方的一个投射区120，多个LED模组110配合照亮车辆200前方的所有投射区120，从而实现分区照明。 Please refer to FIG. 1 , the vehicle headlight 100 in the first embodiment of the present invention is located at the front end of the vehicle 200 , and is no longer divided into two combined headlights on the left and right, but includes a plurality of bright lights arranged in an array at the front end of the vehicle 200 LED module 110. In this embodiment, the width of the plurality of LED modules 110 is approximately equal to the width of the front end of the vehicle 200 , but it is not limited thereto. It can be understood that the number and width of the LED modules 110 can be reduced by reasonably setting the positions and lighting directions of the LED modules 110 . The entire area in front of the vehicle 200 is divided into several projection areas 120, each LED module 110 illuminates a projection area 120 in front of the vehicle 200, and multiple LED modules 110 cooperate to illuminate all projection areas 120 in front of the vehicle 200, Thereby realizing partition lighting.
请参照图2及图3，LED模组110包括反光杯111、位于反光杯111内部的光源112、扣设于反光杯111上的灯板113、设置于反光杯111上的反光层114及安装于灯板113上的感应组件115。 2 and 3, LED module 110 includes reflective cup 111, light source 112 located inside reflective cup 111, light board 113 buckled on reflective cup 111, reflective layer 114 installed on reflective cup 111 and installation The induction component 115 on the lamp board 113 .
反光杯111为椭球形结构，包括杯体1111、由该杯体1111围绕形成的反光腔1112以及杯口1113。较佳地，杯体1111的内表面具有反光作用。杯口1113为一圆形开口，位于杯体1111的末端。可以理解的是，杯口1113也可以为矩形或其他多变形状。 The reflective cup 111 has an ellipsoidal structure and includes a cup body 1111 , a reflective cavity 1112 surrounded by the cup body 1111 and a cup mouth 1113 . Preferably, the inner surface of the cup body 1111 has a reflective effect. The cup opening 1113 is a circular opening located at the end of the cup body 1111 . It can be understood that the cup mouth 1113 can also be rectangular or other varied shapes.
光源112设置于反光腔1112内部，较佳地，光源112设置在反光杯111的焦点上。光源112包括至少一个高亮的LED，其亮度可以调节，以此可以实现车辆前照灯100的光照亮度的调节。另外，光源112可以发射出不同颜色的光线，在行车过程中，针对不同的行车路况，可以将光源112调整为具有不同穿透能力的相应颜色的光束，并且变换光源112的颜色也可以起到警示作用。 The light source 112 is disposed inside the reflective cavity 1112 , preferably, the light source 112 is disposed at the focal point of the reflective cup 111 . The light source 112 includes at least one bright LED, the brightness of which can be adjusted, so as to realize the adjustment of the illumination brightness of the vehicle headlamp 100 . In addition, the light source 112 can emit light of different colors. During the driving process, for different driving conditions, the light source 112 can be adjusted to a light beam of a corresponding color with different penetration capabilities, and changing the color of the light source 112 can also play a role. warning effect.
灯板113扣设于反光杯111的杯口1113上，其为薄片状结构。灯板113的形状与杯口1113的形状相同，以使灯板113可以完全封合杯口1113。灯板113为一透镜，其上设置有用于透光的透光窗1131，灯板113的其余部分为不透光区域。可以理解的是，灯板113也可以为一其上所有区域均透光的透镜，此时灯板113的表面上设置一其上所有区域均不透光的的盖板（图未示），该盖板上开设有透光窗1131。透光窗1131的形状为矩形，用于出射光源112所发出的光线并限制该光线的出射路径，从而使照亮区域形成特定的形状。可以理解的是，该透光窗1131也可以为圆形、三角形或者其他多边形状。 The lamp board 113 is fastened on the cup opening 1113 of the reflector cup 111 , and has a sheet-like structure. The shape of the light board 113 is the same as that of the cup mouth 1113 , so that the light board 113 can completely seal the cup mouth 1113 . The light board 113 is a lens, on which a light-transmitting window 1131 for light transmission is arranged, and the rest of the light board 113 is an opaque area. It can be understood that the lamp board 113 can also be a lens through which all areas are transparent, and at this time, a cover plate (not shown) that is opaque to all areas above is provided on the surface of the lamp board 113 . A light-transmitting window 1131 is opened on the cover plate. The shape of the transparent window 1131 is rectangular, and is used to emit the light emitted by the light source 112 and limit the outgoing path of the light, so that the illuminated area forms a specific shape. It can be understood that the transparent window 1131 can also be circular, triangular or other polygonal shapes.
反光层114位于杯体1111的内表面上的特定区域内，并且与杯口1113相对设置。该特定区域保证光源112发射出的光线经反光层114反射后，通过透光窗1131出射，该出射的光线刚好投射至车辆前方的预定区域，即投射区120内。可以理解的是，反光层114上设置有反光镜或高反射率的反射涂层，以增强光线的出射效果。光源112发射出的光线一部分经由透光窗1131直接出射，一部分经反光层114反射后由透光窗1131出射。由于反光层114的位置的特定设置以及透光窗1131对光线出射路径的限制，从而使出射光线集中投射至预定区域，即投射区120内，而不会投射至其他区域。 The reflective layer 114 is located in a specific area on the inner surface of the cup body 1111 and is opposite to the cup opening 1113 . The specific area ensures that the light emitted by the light source 112 is reflected by the reflective layer 114 and exits through the light-transmitting window 1131 . It can be understood that, the reflective layer 114 is provided with reflective mirrors or reflective coatings with high reflectivity, so as to enhance the outgoing effect of light. Part of the light emitted by the light source 112 is directly emitted through the light-transmitting window 1131 , and part of the light is emitted through the light-transmitting window 1131 after being reflected by the reflective layer 114 . Due to the specific location of the reflective layer 114 and the limitation of the light emission path by the light-transmitting window 1131 , the outgoing light is concentratedly projected into a predetermined area, ie, the projection area 120 , and not projected to other areas.
请同时参照图2及图4，感应组件115 安装于LED模组110的灯板113上，用于侦测车辆200的行驶状况及其前方的路况信息，并反馈该信息至车辆200的照明控制器130。可以理解的是，感应组件115也可以安装在车辆200的前挡风玻璃边缘或者其他位置。该照明控制器130根据感应组件115传输的信息实时做出反应，并发出指令控制该LED模组110的光源112，以根据车辆200的行驶状况及其前方的路况信息，实时更改其照明亮度或照明颜色等，以提供更加适合人眼观看的照明环境。由于多个感应组件115分别安装于多个LED模组110的灯板113上，每个LED模组110对应设置一个感应组件115，该感应组件115用于侦测该LED模组110对应照亮的一个投射区120内的路况信息，因此可以通过照明控制器130控制每一个投射区120的光照情况，从而实现分区明暗的控制以及分区照明颜色的控制。感应组件115可以包括光敏传感器、超声波传感器、角度传感器以及车速传感器等，本发明对此不做限制。 Please refer to FIG. 2 and FIG. 4 at the same time. The sensing component 115 is installed on the light board 113 of the LED module 110 to detect the driving condition of the vehicle 200 and the road condition information ahead, and feed back the information to the lighting control of the vehicle 200. device 130. It can be understood that the sensing component 115 can also be installed on the edge of the front windshield of the vehicle 200 or other positions. The lighting controller 130 reacts in real time according to the information transmitted by the sensing component 115, and issues instructions to control the light source 112 of the LED module 110, so as to change its lighting brightness or Lighting color, etc., to provide a lighting environment that is more suitable for human eyes. Since a plurality of sensing components 115 are respectively installed on the lamp boards 113 of a plurality of LED modules 110, each LED module 110 is provided with a corresponding sensing component 115, and the sensing component 115 is used to detect that the LED module 110 is illuminated correspondingly. Therefore, the lighting condition of each projection area 120 can be controlled by the lighting controller 130, so as to realize the control of the brightness and darkness of the zones and the control of the lighting color of the zones. The sensing component 115 may include a photosensitive sensor, an ultrasonic sensor, an angle sensor, a vehicle speed sensor, etc., which is not limited in the present invention.
当车辆200前方的部分区域有凹坑时，感应组件115能够侦测该路况信息，并反馈该信息至车辆200的照明控制器130，该照明控制器130根据该信息实时做出反应，发出指令以合理加强该LED模组110的光源112的照明亮度，从而提高该凹坑区域的可视度，使驾驶员能够及时发现该凹坑，避免车辆驶入凹坑。同样的，当车辆200前方的部分区域存在高反光物体时，感应组件115能够侦测该路况信息，并反馈该信息至车辆200的照明控制器130，该照明控制器130根据感应组件115反馈的该高反光物体反射的光线强度等信息实时做出反应，发出指令以合理减弱该LED模组110的光源112的照明亮度，从而避免高反光物体反射强光进入人眼，造成人眼短暂失明。 When there is a pothole in a part of the area in front of the vehicle 200, the sensing component 115 can detect the road condition information, and feed back the information to the lighting controller 130 of the vehicle 200, and the lighting controller 130 responds in real time according to the information and sends an instruction The illumination brightness of the light source 112 of the LED module 110 is reasonably enhanced, thereby improving the visibility of the pit area, so that the driver can find the pit in time and avoid the vehicle from driving into the pit. Similarly, when there is a highly reflective object in a part of the front of the vehicle 200, the sensing component 115 can detect the road condition information and feed back the information to the lighting controller 130 of the vehicle 200.
