Description

Single light source double beam motor vehicle light

Technical field

The utility model relates to a vehicle illumination lamp, in particular to a motor vehicle illumination lamp which can generate double beams based on a single light source.

Background technique

At present, motor vehicle lighting is divided into structures, which can be divided into independent lamps with far and near light separation and hybrid lamps with the same reflective bowl for far and near light. They can be divided into reflective illumination lamps and lenticular illumination lamps. .

As we all know, the high beam is more effective because of its dazzling effect. In addition to being used in extremely dark nights and foggy conditions, the driver usually uses the low beam for a long time. In the national standard, the low beam is defined as: the road in front of the illuminating vehicle, which does not cause glare or discomfort to the driver and other road users. In other words, the low beam should be both distant and wide, but not dazzling.

However, the existing reflective low beam and lenticular low beam have their own defects, which cannot meet the requirements of the current national standards. When used in China, where there are many pedestrians and non-motor vehicles, there are many drawbacks. . The following descriptions of the reflective low beam and the lenticular low beam are respectively described.

Because of the design of the reflective bowl, the reflective low beam can make the central part of the beam have higher brightness, longer illumination distance and wider illumination. However, due to the diffraction principle of light, it is difficult to form a good dividing line. Therefore, only light sources with low illumination can be used. If you use a light source with a higher illumination, it will produce a noticeable glare. However, with the improvement of technology, the reflective efficiency of reflective bowls has gradually increased, especially the reflective bowls of SUVs and wagons are relatively large, and the installation position is high. Therefore, even if the reflective low beam adopts 55W halogen lamps, Very dazzling. At present, most of the ordinary vehicles use it because of the low cost of the reflective low beam lamp. However, when the vehicle density is high, the light pollution caused by the reflective low beam lamp is obvious.

The structure of the lenticular low beam lamp is as shown in FIG. 1 , and includes a reflective bowl 11 . The reflective bowl 11 is provided with a lens 12 at the port. The bottom of the reflective bowl 11 is provided with a light source 13 coaxial with the lens 12 . In the reflector bowl 11, a light shielding plate 14 is provided between the lens 12 and the light source 13 and below the central optical axis L'. The working principle is: when the light source 13 emits light, the light is irradiated onto the external object through the lens 12, and the light shielding plate 14 under the central light axis L' blocks the light of the lower half, so that the upper half of the object is projected onto the object. A distinct dividing line appears between the light and the occluded lower half of the light. Here, the portion of the light that is normally projected onto the object is referred to as the main beam, and the portion of the light that is blocked by the visor 14 without producing an illumination effect is referred to as a discarded beam. In actual use, it can be found that in the process of forming the main beam by the lenticular low beam, the loss of the abandoned beam is serious. Therefore, the lenticular low beam is obviously present. Defects with low light utilization. Because of this, most of the lenticular low beam lamps installed in vehicles now use high-intensity xenon lamps. If halogen lamps are used, the halogen lamps cannot see the road due to low brightness under the same outdoor illumination. The driving speed is greatly reduced and it is very impractical.

In the existing lenticular low beam lamp, the distance between the lens 12 and the light source 13 is designed to obtain a main beam having a large condensing angle, and the distance between the main lens 21 and the light source 24 of the illumination main member is increased. Reduce the concentration angle of the main beam to increase the brightness.

The double-lens composite low beam lamp makes full use of the abandoned beam through the main reflector, the sub-reflector and the secondary lens on the basis of obtaining the main beam having the frontal illumination effect through the main lens, so that the abandoned beam becomes a side illumination effect. The beam (recovery beam) is emitted, so that the two-lens composite low beam illuminates the two beams. The two beams have different axes, and the illuminating position of the recovered beam can be arbitrarily arranged. The advantages of the two-lens composite low beam lamp are as follows: 1. The main beam of the existing lenticular low beam lamp has to take into account the illumination width, but in the double lens composite low beam, the illumination width of the double beam due to different axes It is already very wide, and the illumination width can be adjusted by retrieving the beam. Therefore, it is only necessary to take into account the depth of illumination, that is, to the road surface, and the illumination width is inversely proportional to the brightness, such as the illumination width is reduced to 1/3 of the original. When it is between 1/4, the brightness can be increased by more than 3 times. 2. The direction of the beam can be adjusted freely, which is more conducive to the driver to watch other road users on the roadside, especially when turning. 3. The two illumination beams share one light source, thus improving energy utilization and can be widely applied to low-power vehicles and energy-saving vehicles. 4, to maintain the existing lenticular low beam is not dazzling features.

The transflective composite low beam lamp obtains the main beam with the frontal illumination through the main lens, and makes full use of the abandoned beam through the main reflector, the sub-reflector, or the main reflector and the reflective bowl, so that the abandoned beam becomes The beam (recovery beam) having a side illumination effect is emitted, so that the transflective composite low beam lamp realizes double beam illumination, and the two beams have different axes, and the illumination position of the recovered beam can be arbitrarily arranged. The advantages of the transflective composite low beam lamp are as follows: 1. The double-lens composite low beam lamp has the advantages of wide illumination width, freely adjustable illumination direction of the recovered beam, and high energy utilization rate. 2. For the third and fourth embodiments of the present invention, first, the light utilization rate is high because the light focused by the main lens is direct light, and the scattered light cannot pass through the main lens, and the main reflector and the reflective bowl can not only The use of the abandoned beam can also make full use of the scattered light that cannot pass through the main lens. Secondly, it can be obtained by modifying the existing vehicle headlights, and the manufacturing cost is low, which is especially suitable for economical vehicles. Third, in the reflective bowl. The installation of the main lens makes the non-glare main lens block the brightest part in the middle of the reflective bowl, and presents an aura like angel eye from the outside, which is both beautiful and safe.

The above is a preferred embodiment of the present invention and the technical principles applied thereto, and any technical solution based on the present invention can be made by those skilled in the art without departing from the spirit and scope of the present invention. Obvious changes such as equivalent transformation, simple replacement, etc. are all within the scope of protection of the present invention.
