Description

Superimposed asymmetric light headlight

The invention relates to the technical field of the structure of an asymmetric light type headlight of an automobile, in particular to a method which has no diffused light and unnecessary stray light, can generate a clear cut-off line without using a visor, and can conform to Superimposed asymmetric light headlamps with ECE R112 regulations and other functions.

Please refer to Figure 1 for a schematic diagram of the ECE R112 asymmetric light headlights regulation. It is clearly stated in the regulations that the low beam type must provide a clear cut-off, in the right traffic system. When the cut-off line is based on the VV line, the left side of the cut-off line is a horizontal line HH extending to the left, mainly to prevent glare from driving to the oncoming vehicle, and the cut-off line on the right is the oblique line formed by H-H1. The upper 15° slash is mainly used to illuminate vehicles, pedestrians and traffic signs in front of the road to ensure safe driving. In the left traffic system, the horizontal line H-H and the 15° oblique line H-H1 are opposite to each other. In addition to the limit of the cut-off line, there is a limitation of illumination on each test point or area on the 25m observation screen.

At present, the conventional automobile headlight design has two designs of a projection type lamp and a multiple reflection type lamp in order to comply with the above-mentioned ECE R112 asymmetric light type headlight regulation.

A conventional projection type lamp, such as Taiwan Announcement No. I261097 In addition, it mainly reflects the light of a light source through a reflecting surface, and uses a specific shape of the light shielding plate to sculpted the reflected light to meet the cut-off line of the ECE R112 asymmetric light headlight regulations. The light type is finally formed by adding a focusing lens to the front of the visor to enable the light to be emitted in parallel. However, since such a projection type lamp uses the shielding of the visor to form a desired light type, in order to make the illuminance of each area conform to the specification, the illuminance of the light source must be high, and the relative light consumption is relatively high. If the visor blocks the light, it will form another heat source in the luminaire, which will cause the temperature inside the luminaire to be too high, thus shortening the service life.

Another conventional multi-reflective vehicle lamp, as shown in the patent No. I491833, is mainly composed of a structure of a plurality of reflecting surfaces, and the parabolic reflecting surface is subdivided into reflecting surfaces of a plurality of small units, and each small unit is designed to be reflected. The curvature and rotation of the surface are such that the reflected light is repeatedly superimposed to meet the light and illumination standards of the cut-off line of the ECE R112 asymmetric light headlight. However, the multi-reflective lamp not only has difficulty in designing the curvature and rotation mode of the reflecting surface of the small unit, but also is time consuming and costly, especially in that it is easy to generate diffused light and unnecessary. Stray light.

Generally, asymmetrical optical headlamps have troubles in designing, high cost, easy to generate diffused light and unnecessary stray light, and require a visor to be more energy-intensive and easily cause internal temperature of the lamp. Too high, and thus shorten the service life and many other problems.

The invention provides a superposition type asymmetric light type headlight, comprising a a first light group, a second light group and a third light group. The first lamp set includes a first lamp holder and a first LED lamp. The first lamp holder has at least one reflective surface. The first LED lamp is disposed on the first lamp holder and can direct the light. The reflective surface on the first socket causes the light to be reflected forward. The second lamp set includes a second lamp holder and a second LED lamp. The second lamp holder has at least one reflective surface. The second LED lamp is disposed on the second lamp holder and can direct the light to the first lamp holder. The reflective surface on the two lamp holders to reflect the light forward. The third lamp set includes a third lamp holder, a third LED lamp and a vertical portion having a narrow bottom width, and the horizontal portion is a narrow outer side width to make a 15 degree oblique angle refraction lens, the third lamp holder Having at least one reflective surface, the third LED lamp is disposed on the third lamp holder and can direct the light to the reflective surface on the third lamp holder to reflect the light forward, and the refractive lens is disposed on the first The front side of the three lamp holders is used to refract light and then project it out. The light pattern projected by the first lamp group and the second lamp group can be superimposed on a 25m observation screen to form a narrow rectangular light pattern located at a 0° horizontal line to a position 25 cm below, and the third light group can be observed at 25 m. A narrow light pattern of 15° oblique angle is projected on the screen, and the upper side of the narrow light pattern passes through the intersection of the 0° horizontal line and the 0° vertical line, the first light group, the second light group and the third The light groups can be superimposed to form a light pattern and illumination that comply with the ECE R112 asymmetric light headlight regulations.

The superimposed asymmetric light type headlight provided by the present invention can be designed to respectively project a specific shape light pattern by the first light group, the second light group and the third light group, and then They are combined so that they can be superimposed on one another to form a light pattern and illuminance in accordance with the ECE R112 asymmetric light headlights regulations, so that the alignment of the fixed light patterns can be achieved such that no stray light and unnecessary stray light are produced, Use a visor It can produce clear and dark cut-off lines and can comply with ECE R112 regulations, and this superimposed light type can also make the production of the lamps simpler and lower the cost, and can also effectively reduce the temperature of the lamps.
