对于上述基于LED的车灯，两组LED光源择其一组点亮，但无论那一组的LED光源点亮，其均不是完全产生照向车灯前后方向的光，而是使用产生照向车灯侧面的光，此侧光经过反光杯的作用之后打向前方，目前人们设计的LED车灯都是落入这个技术设计思路，采用模拟灯丝灯方式，再利用反光杯将光线以反射的方式打出去。For the above LED-based headlights, the two sets of LED light sources are selected to illuminate one set, but no matter which group of LED light sources are lit, they are not completely generating light that is directed to the front and rear directions of the lights, but are used to generate illumination. The light on the side of the lamp, the side light is turned to the front after the action of the reflector. At present, the LED lights designed by people are falling into this technical design idea, using the analog filament lamp method, and then using the reflector to reflect the light. Way to fight out.
基于此作用原理，上述两组LED光源的位置与基座有较长的距离，使得传导片过长，增加了LED光源的散热难度，影响整个车灯的造价或性能的体现。Based on this principle of action, the positions of the two sets of LED light sources have a long distance from the base, so that the conductive sheets are too long, which increases the difficulty of heat dissipation of the LED light source and affects the cost or performance of the entire vehicle.
另外，基于车灯设计的标准要求，对于作为近光灯使用的前照灯，需要让从前照灯发出的光斑具有较为清晰的明暗截止线；对于作为远光灯使用的前照灯需要形成打向远方的汇聚的光斑，目前为了形成明暗的截止线和汇聚的光斑，往往需要非常复杂的结构。In addition, based on the standard requirements of the design of the lamp, for the headlamp used as the low beam, the spot from the headlight needs to have a clear cut-off line; for the headlight used as the high beam, it needs to be formed. The spot that converges in the distance, at present, often requires a very complicated structure in order to form a light-dark cut-off line and a concentrated spot.
有鉴于此，本申请人针对上述缺陷深入研究，遂有本案产生。In view of this, the applicant has conducted in-depth research on the above defects, and this case has not been produced.

具体实施方式detailed description
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。In order to further explain the technical solutions of the present invention, the present invention will be described in detail below by way of specific embodiments.
如图1至图13所示，该LED的前照灯包括LED光源和散热组件，该散热组件具有导热件以及与导热件相连的若干个散热片；该导热件的安装面具有正前方朝向，该LED光源贴设在安装面上；该LED的前照灯还包括用于形成远光汇聚光斑和近光明暗截止线的光斑成型装置。As shown in FIG. 1 to FIG. 13 , the headlight of the LED comprises an LED light source and a heat dissipating component, the heat dissipating component has a heat conducting component and a plurality of fins connected to the heat conducting component; the mounting surface of the heat conducting component has a front direction, The LED light source is attached to the mounting surface; the LED headlight further includes a spot forming device for forming a high beam convergence spot and a low beam cutoff line.
这样，本发明涉及的一种LED的前照灯，由LED光源产生的光是一个类似于点光源产生的光，其照明是朝向前方，在凸透镜的作用下形成符合当前国家或地区标准所需要的近光或者远光（其可以为散光角度较大或较小的发散光束），由于原理上区别于现有技术，因此该导热件不需要过多的长度，这样就能够减少LED光源的散热难度，确保了整个LED远近两用的车用灯具之使用寿命。Thus, the present invention relates to an LED headlamp, the light generated by the LED light source is a light generated by a point source, the illumination is directed forward, and formed by the convex lens to meet current national or regional standards. The low beam or the high beam (which may be a diverging beam with a larger or smaller astigmatism angle), because the principle is different from the prior art, the heat conducting member does not need excessive length, so that the heat dissipation of the LED light source can be reduced. Difficulty ensures the service life of the entire LED for the dual-use automotive luminaire.
如图1和图2所示，其为本发明的第一实施例，其包括外壳11、LED光源12、散热组件13以及远近光切换机构，该散热组件13具有导热件131以及与导热件131热传导相连的若干个散热片132。As shown in FIG. 1 and FIG. 2 , it is a first embodiment of the present invention, which includes a housing 11 , an LED light source 12 , a heat dissipation assembly 13 , and a near-and-near-light switching mechanism. The heat dissipation assembly 13 has a heat-conducting member 131 and a heat-conducting member 131 . A plurality of fins 132 connected by heat conduction.
该导热件131具有朝向正前方的安装面1311，该LED光源12贴设在安装面1311上；该LED车用灯具还包括位于LED光源12出光光路前方以对LED光源12产生光线进行引导的凸透镜，该LED光源12的中心位于凸透镜的光轴上，该远近光切换机构设置在位于LED光源12出光方向上且位于凸透镜的前方。The heat conducting member 131 has a mounting surface 1311 facing forward, and the LED light source 12 is attached to the mounting surface 1311. The LED vehicle lamp further includes a convex lens located in front of the light path of the LED light source 12 to guide the light generated by the LED light source 12. The center of the LED light source 12 is located on the optical axis of the convex lens, and the near-far light switching mechanism is disposed in the light-emitting direction of the LED light source 12 and located in front of the convex lens.
该LED光源与等效光学的凸透镜之间的灯具距离在一倍或超过一倍焦距的位置，形成有效利用的近似平行光束或散光角度较小的沙漏形光束。The distance between the LED light source and the equivalent optical convex lens is one time or more than one focal length, forming an approximately parallel beam or an hourglass beam having a small astigmatism angle.
在第一实施例中，该凸透镜14和远近光切换机构构成光斑成型装置。In the first embodiment, the convex lens 14 and the near-and-near light switching mechanism constitute a spot forming device.
这样，由LED光源12产生的光是一个类似于点光源产生的光，其朝向的是前方，在凸透镜的作用下形成符合当前国家或地区标准所需要的近光或者远光（其可以为散光角度较大或较小的发散光束），由于原理上区别于现有技术，如此其导热件131无需伸出那么长，并且由于LED光源12是贴设在朝向正前方的安装面1311，也能一定程度上缩短导热件131的长度，这样将会减少LED光源12的散热难度，确保了整个LED车用灯具的使用寿命。Thus, the light generated by the LED light source 12 is a light generated similarly to a point source, which is oriented toward the front, and forms a low beam or a high beam (which may be astigmatism) required by the current national or regional standards under the action of the convex lens. The diverging beam having a larger or smaller angle is different in principle from the prior art, so that the heat conducting member 131 does not need to be extended as long, and since the LED light source 12 is attached to the mounting surface 1311 facing forward, The length of the heat conducting member 131 is shortened to some extent, which will reduce the heat dissipation of the LED light source 12 and ensure the service life of the entire LED vehicle lamp.
作为更进一步的较佳实施例，如图1和图2所示，该远近光切换机构具有设置在凸透镜前方的遮光片15以及用于控制遮光片15在第一位置和第二位置之间切换的驱动机构16，该遮光片15处于第一位置时该LED车用灯具处于远光工作状态，该遮光片15处于第二位置时该LED车用灯具处于近光工作状态，该遮光片处于第一位置时该LED车用灯具处于远光工作状态，该遮光片处于第二位置时，会遮住近光灯不需要的光形成有明暗截止线。As still further preferred embodiments, as shown in FIGS. 1 and 2, the near-and-near-light switching mechanism has a light shielding sheet 15 disposed in front of the convex lens and for controlling the light shielding sheet 15 to switch between the first position and the second position.

In one position, the LED vehicular lamp is in a high beam working state, and when the visor is in the second position, the light that is not required by the low beam is formed with a cut-off line.
在本实施例中，该驱动机构16采用继电器来实现，尤其是采用电磁继电器，该电磁继电器处于上电状态时，该遮光片15会被吸下来处于第一位置状态，更优选地，该遮光片15还连接有复位弹性件，利用此复位弹性件可以让遮光片15可以自动由第一位置切换到第二位置，如此方便了两个位置之间的切换。In the embodiment, the driving mechanism 16 is implemented by using a relay, in particular, an electromagnetic relay. When the electromagnetic relay is in a power-on state, the light shielding sheet 15 is sucked down to be in a first position state, and more preferably, the light shielding is performed. The sheet 15 is also coupled to a return resilient member by which the shutter 18 can be automatically switched from the first position to the second position, thus facilitating switching between the two positions.
为了满足近光灯相关标准的要求，该遮光片边沿还形成有明暗截止线。更具体地，该第一位置处于底部位置，该第二位置处于第一位置的上方；该LED车用灯具还包括设置在遮光片15前方使用第二凸透镜17。以形成散光角度较小或较大的散光光束的，可以非常清晰地显示出明暗截止线和更佳的显示效果。In order to meet the requirements of the low beam related standard, the visor edge is also formed with a cut-off line. More specifically, the first position is in a bottom position and the second position is above the first position; the LED vehicular lamp further includes a second convex lens 17 disposed in front of the light shielding sheet 15. In order to form an astigmatic light beam with a small or large astigmatism angle, the cut-off line and the better display effect can be clearly displayed.
如图1和图2所示，该LED远近两用的车用灯具还包括安装平台18以及两个L形固定件181，每一L形固定件181都具有竖直臂和水平臂，该水平臂与安装平台18锁固相连，该竖直臂与外壳11锁固相连，该外壳11呈圆筒状，该外壳11上还设置有用于定位凸透镜的连接槽。更具体地，为了方便安装遮光片15和第二凸透镜17，该外壳11还向外延伸形成安装部111，且该安装部111还形成有便于遮光片15和驱动机构16安装的镂空区域112。As shown in FIG. 1 and FIG. 2, the LED luminaire for a near-and dual-purpose LED further includes a mounting platform 18 and two L-shaped fixing members 181, each of which has a vertical arm and a horizontal arm, the level The arm is fixedly connected to the mounting platform 18, and the vertical arm is fixedly connected to the outer casing 11.
