车用投影灯以及车前灯Car projection lamps and headlights

技术领域technical field

本发明涉及一种应用于车辆的车前灯，具体而言，涉及一种可替换原有车前灯的卤素灯泡的车用投影灯以及包括这种投影灯的车前灯。 The present invention relates to a headlight applied to a vehicle, in particular to a projection lamp for a vehicle which can replace the halogen bulb of the original headlight and a headlight including the projection lamp. the

背景技术Background technique

现有的车前灯一般使用卤素大灯，其光照性能一般。图1和图2示出了传统车前灯的灯泡安装结构的示意图，所述灯泡安装结构包括：用于容纳灯泡的反光罩11；设置在反光罩底部上的安装孔12，用于使灯泡的底座穿过；从安装孔12向反光罩11的外侧一体延伸形成的延伸部；形成在延伸部上的定位槽13；形成在所述反光罩11背面并位于所述延伸部外围的外罩14；设置在所述外罩14的与反光罩连接的一端相对的另一端的开口部15，所述开口部15的轴线与所述反光罩11上的安装孔12的轴线同轴；用于覆盖所述开口部15的端盖16；设置在所述端盖16上的导线导入口17；以及设置在所述导线导入口附近的防水密封塞18。 Existing car headlights generally use halogen headlights, and their illumination performance is general. Fig. 1 and Fig. 2 have shown the schematic diagram of the bulb installation structure of traditional car headlight, and described bulb installation structure comprises: be used to accommodate thereflector 11 of bulb; Be arranged on theinstallation hole 12 on the reflector bottom, be used to make bulb The base passes through; the extension formed integrally extending from themounting hole 12 to the outside of thereflector 11; thepositioning groove 13 formed on the extension; theouter cover 14 formed on the back of thereflector 11 and located at the periphery of the extension ; Theopening 15 at the other end opposite to the end connected to thereflector 14 of theouter cover 14, the axis of theopening 15 is coaxial with the axis of themounting hole 12 on thereflector 11; used to cover the Theend cap 16 of theopening portion 15; thewire inlet 17 arranged on theend cap 16; and thewaterproof sealing plug 18 arranged near the wire inlet. the

目前在一些车辆中使用氙气灯代替卤素灯，氙气灯的光性能好但造价较高。但随着氙气灯制作技术的改进，造价趋于降低，因此越来越多的车主考虑将卤素灯更换为氙气灯，但更换灯泡除了考虑造价外，氙气灯和原有灯泡安装结构之间的匹配性和配光效果也是必须考虑的因素。由于各款式汽车的灯泡安装结构千变万化，故难于生产出可统一使用而且与原有灯泡安装结构的匹配性和配光效果都很号的氙气灯，更换时甚至可能要破坏原有灯泡安装结构。总之，直接使用氙气灯泡更换原有的卤素灯并不理想，可能无法获得良好的配光光形，有时甚至破坏原有的灯泡安装结构。 At present, xenon lamps are used instead of halogen lamps in some vehicles. The light performance of xenon lamps is good but the cost is high. However, with the improvement of xenon lamp production technology, the cost tends to decrease, so more and more car owners consider replacing halogen lamps with xenon lamps. Matching and light distribution effects are also factors that must be considered. Due to the ever-changing bulb installation structures of various models of cars, it is difficult to produce xenon lamps that can be used uniformly and have excellent matching and light distribution effects with the original bulb installation structures. The original bulb installation structure may even be destroyed when replacing. In short, it is not ideal to directly use xenon bulbs to replace the original halogen lamps. It may not be possible to obtain a good light distribution and light shape, and sometimes even destroy the original bulb installation structure. the

后来人们将投影灯作为车前灯使用，该投影灯一般包括曲面反射体、透镜和带遮光片的远近光切换装置，曲面反射体底部设有用于安装光源的开口。该投影灯的光源通常使用氙气灯。由于不论是远光情况下或切换成近光灯时，投影灯都能获得良好的配光光形，故越来越多的人考虑使用投 影灯，有人提出将投影灯直接安装在现有的卤素车前灯的安装结构上，以代替现有的卤素灯泡，此时原有的灯泡安装结构的灯罩不再用于反射配光，这样就不用再去考虑更换后配光的匹配性了。但怎样将投影灯穿过反光罩的安装孔而安装投影灯的灯体而又不破坏原有的灯泡安装结构，则是一个值得考虑的问题。 Later, people used projection lamps as car headlights. The projection lamps generally include a curved reflector, a lens, and a far and low beam switching device with a light-shielding sheet. The bottom of the curved reflector is provided with an opening for installing a light source. A xenon lamp is generally used as a light source for the projection lamp. Since the projection lamp can obtain a good light distribution shape no matter in the case of high beam or when switching to low beam, more and more people consider using the projection lamp. Some people propose to install the projection lamp directly on the existing The installation structure of the halogen car headlights is used to replace the existing halogen bulbs. At this time, the lampshade of the original bulb installation structure is no longer used for reflection light distribution, so that there is no need to consider the matching of light distribution after replacement. . But how to pass the projection lamp through the installation hole of the reflector to install the lamp body of the projection lamp without destroying the original bulb installation structure is a problem worth considering. the

Afterwards, thepositioning ring 23 and the fixing ring are mounted on the cylindrical body from the back side of thereflector 11 of the halogen vehicle headlight and theouter positioning pin 25 of thepositioning ring 23 is inserted into thepositioning groove 13 of thereflector 11 of the halogen vehicle headlight , Install thewasher 39 again, then tighten the first fixing device 26 (fixing ring), so that the installation part 21 (cylinder) of the projection lamp is locked on the bulb installation structure of the halogen headlight. Then, insert theilluminant 27 of the light source through the cylinder and therear opening 33 into thecurved reflector 2 from the rear of the cylinder, install thewasher 31, and then fasten thesecond fixing device 30. Then, cover the front transparent cover plate of the lampshade, install thewaterproof sealing plug 18 at the rear portion of the mounting seat 32 of the light source simultaneously, and then theend cover 16 is installed on theouter cover 14 . Finally, the wires from the power supply enter the inner side of the end cover 16 from thewire inlet 17, and pass through a plurality of wire perforations arranged on the sealingplug 18 to be connected to the bulb base installed in the extension, thereby supplying power to the bulb . the

根据本发明的投影灯可直接安装在传统卤素车前灯的灯泡安装结构上，不但不会破坏原车前灯的结构，因此安装方便，而且可以较低的价格直接使用配光性好的投影灯。 The projection lamp according to the present invention can be directly installed on the bulb installation structure of the traditional halogen car headlight, not only will not damage the structure of the original car headlight, so it is easy to install, and can directly use the projection lamp with good light distribution at a lower price lamp. the

上面描述了，将根据本发明的车用投影灯安装在原有车前灯的灯泡安装结构上的实施例。但本发明也不局限于此，本领域的技术人员可以理解，也可利用根据本发明的车用投影灯形成一种和原有卤素车前灯的外部结构相同的完整的车前灯，以将这种包括本发明的投影灯的车前灯方便地安装到车辆上，而不必修改车辆本身的其它结构。即这种车前灯包括根据本发明提供的车用投影灯和原有车辆的灯泡安装结构。在另一种实施例中，由于投影灯本身具有可以对光源发出的光束进行发射的曲面反射体，因此可用形状和结构与原有反光罩相同的外罩代替原有车前灯反光罩，即前罩不具有反光性能，这样可降低车前灯的成本。 The above describes the embodiment in which the projection lamp for a vehicle according to the present invention is mounted on the bulb mounting structure of the existing headlight. However, the present invention is not limited thereto. Those skilled in the art can understand that the vehicle projection lamp according to the present invention can also be used to form a complete headlight with the same external structure as the original halogen headlight, so as to Such a headlight including the projection lamp of the present invention can be easily mounted on a vehicle without modifying other structures of the vehicle itself. That is, the vehicle headlight includes the vehicle projection lamp provided by the present invention and the original vehicle bulb installation structure. In another embodiment, since the projection lamp itself has a curved reflector that can emit the light beam emitted by the light source, the original reflector of the headlight can be replaced by an outer cover with the same shape and structure as the original reflector, that is, the front reflector. The cover does not have reflective properties, which can reduce the cost of the headlight. the

尽管对本发明的典型实施例进行了说明，但是显然普通技术人员可以理解，在不背离本发明的精神和原理的情况下可以进行改变，其范围在权利要求书以及其等同物中进行了限定。 While exemplary embodiments of this invention have been described, it will be apparent to those of ordinary skill that changes may be made without departing from the spirit and principles of the invention, the scope of which is defined in the claims and their equivalents. the
