For vehicle headlights, especially for automobiles, C-
There is a bulb called a 6/C-6 type bulb which has two filaments, a main filament and a sub filament, which are perpendicular to the optical axis and parallel to the horizontal direction (hereinafter referred to as a C-6/C-6 type bulb). A conventional headlamp using this type of bulb is shown in FIG. a reflector b having a focal point at the center of the optical axis;
It consists of a lens d that covers the front surface of a reflector b, and a bulb a in which a main filament is placed between the two members at the focal point of the reflector b. Here, the positions of subfilaments a 2 and a′ 2 are reversed when used in left-hand driving countries such as Japan and right-hand driving countries such as the United States, and the left side In the case of traffic, the subfilament a2 is placed to the upper left of the main filament a1 , as shown in FIG. When driving on the right side, the subfilament a′ 2 as shown in Figure 3
is located above and to the right of the main filament a′ 1 . For example, in the case of right-hand traffic, as shown in the front view of reflector b in Figure 4, reflector b is divided into three parts: lower left part B, lower right part C, and other part A. , the A section and the B and C sections have different light distribution patterns.
FIGS. 5 to 8 are diagrams showing light distribution patterns in which light reflected from various parts of the reflector due to lighting of a bulb is projected onto a screen without passing through a lens, and the hatched area is the reflection range. 5 and 6 show the light distribution pattern when the subfilament is turned on. FIG. 5 shows the light distribution pattern of the reflected light in the A section, and FIG. 6 shows the light distribution pattern of the reflected light in the B and C sections. As shown in the figure, the light distribution pattern of section A is directed almost below the horizontal line H-H, obtaining the desired light distribution pattern, but the light distribution pattern of sections B and C is largely oriented below the horizontal line H-H. It is facing higher than H. Also, the seventh
Figures 7 and 8 are for when the main filament is lit. Figure 7 shows the light distribution pattern in section A, and Figure 8 shows the light distribution pattern in sections B and C. The light distribution pattern in section A is approximately horizontal line H. Although the desired light distribution pattern is obtained by facing above -H, a considerable portion of the light distribution pattern of sections B and C is directed below horizontal line H-H.

In this way, the light distribution pattern of sections B and C is different from that of section A, but since there is a problem with the upward light especially when the subfilament is turned on, conventionally, a prism is formed on the front lens. The reflected light was directed downward and diffused. However, if the light is simply directed downward, the light distribution pattern will be directed downward when the main filament is turned on, and if the reflected light is directed downward and diffused by the prism of the lens, the thickness of the lens will become thicker. There is a problem with putting it away.

しまうという問題がある。 As described above, in the conventional technology, there is a problem that the light distribution pattern is downward when the main filament is turned on, and that when the lens becomes thick, sink marks are formed on the lens surface, the appearance is poor, and the lens is heavy. .

As described above, in the vehicle headlamp of the present invention, when the reflector is attached to a vehicle, two reflective surfaces, the diagonally upper part and the diagonally lower part, which are located symmetrically with respect to the center position, are positioned from the center of the bulb. The reflective surface has a focal point above the sub-filament that is shifted diagonally upward, and the other reflective surfaces are composed of reflective surfaces that have a focal point at the center of the bulb sandwiched between the main filament and the sub-filament. When the subfilament is turned on, the light reflected from the diagonally upper part and the diagonally lower part is reduced, and this and the reflected light from other parts overlap to achieve the desired misalignment without forming a prism on the lens. The light distribution pattern of the beam can be obtained. In addition, when the main filament is turned on, the reflected light reflected from the diagonally upper part and the diagonally lower part is not reduced much, and this and the reflected light reflected from other parts overlap to achieve the desired main beam light distribution. You can get the pattern.

が、多少違つていてもよい。 As described above, when the reflector is shaped as described above, when the subfilament is turned on, the light distribution pattern of the reflected light is directed downward in all parts, resulting in the desired light distribution pattern, so the prism of the front lens There is no need to lower the light distribution pattern to the side to diffuse it. Therefore, no glare is generated, and the light distribution pattern of the main filament is not affected at all. In addition, since there is no need for prismatic action, the thickness of the lens can be reduced, no sink marks will occur on the lens surface, and the appearance will be better.
It becomes lighter. In the above embodiment, the distances F from the reflective surface of the first focal point and the second focal point are set to be the same, but they may be slightly different.
