Description

TECHNICAL FIELD The present invention relates to a headlamp which is used by being mounted on a vehicle such as an automobile and in which a reflector is divided into a plurality of parts.

[Conventional technology]

As this type of divided reflecting mirror, one having a configuration disclosed in Japanese Utility Model Application Laid-Open No. 59-118201 is commonly known. In this known reflecting mirror, the reflector is divided into two, and the length relationship and the positional relationship between the running filament and the passing filament used are clearly divided, and in particular, the running filament is 0 to 1 more than the passing filament. It was clarified that it was formed to be 0.5 mm longer, and that the traveling filament of both filaments was in a position orthogonal to the vertical line and the passing filament was shaken on the parabolic center axis or at a constant width. There is.

[Problems to be solved by the invention]

In the above conventional example, the traveling filament is positioned so as to be orthogonal to the vertical line, so that dazzling light is not generated for an oncoming vehicle when a headlamp for right-hand traffic and left-hand traffic is formed. Therefore, there is a problem that it is difficult to adjust the light distribution pattern.

As a solution to this problem, an invention by the same applicant was filed as Japanese Patent Application No. 61-85494. The invention of this prior application also has a problem that the traveling beam hot zone cannot be enlarged because the reflector has a two-division structure and the light distribution pattern of the passing beam is emphasized.

In addition, since the reflector is divided into two parts, when the valve used has a high W, the road surface irradiation between the traveling beam and the passing beam does not cause a large difference in switching between the irradiation patterns, so the driver It also has a problem that there is no sense of switching.

The upper central reflector, the upper right reflector, and the lower lower reflector, each of which is composed of four divided parabolic reflectors, and the focal point of each of the upper central reflectors is the focal length of the upper central reflector. Are formed to be longer than the focal lengths of the other paraboloids of rotation, and the focal point of the upper central reflector, the focal point of the upper left reflector and the focal point of the upper right reflector are on the front center axis and at the upper central reflector. The focal point rearward (reflector side) has both focal points of the upper left and right reflectors, and the focal point of the lower reflector is forward from the focal point of the upper central reflector by at least the longitudinal length of the passing filament. In addition, it is formed below the central axis in the front direction and has a non-passing filament. Between the focal point of the upper central reflector and the focal point of the lower reflector, the front central axis and the longitudinal direction of the filament are arranged substantially parallel to and slightly above, and the traveling filament is The front central axis and the filament longitudinal direction are arranged substantially parallel and downward so that the front end of the filament is located near the focal point of the lower reflector, and the longitudinal central axis of the traveling filament is Centering on the central axis in the longitudinal direction, passing through the central axis of the passing filament, and being within a range of 0 to 45 ° when viewed from the front from a vertical line parallel to the vertical line,

The central axis X and the longitudinal central axis 6a of the running filament are arranged so as to be located at a position about 3 mm ahead of each other so as to be parallel or substantially parallel. (See FIG. 2 (A)) Moreover, the running filament 6 is the central axis 5a in the longitudinal direction of the passing filament 5 which is substantially parallel to the central axis X.

In addition, the length of the traveling beam filament is the same as the length of the passing beam filament at the maximum.

FIGS. 3 to 4 show spot light patterns in a reflection state of the passing filament 5 and the traveling filament 6 in the reflector in the above-mentioned arrangement state. In the figure, the spots when the distance d ₃ = 0 mm and the range θ = 0 ° are set so that the passing filament 5 and the traveling filament 6 are both arranged on the vertical line V for easy understanding. This is a light pattern, and the length of both filaments 5 and 6 is 4 mm.

First, the pattern of the passing filament 5 will be described. By arranging the passing filament 5 above the central axis X of the front direction of the reflector A and by arranging it in front of the focal point f ₁ of the upper central reflector 1, The light generated between the front end and the rear end of the passing filament is divided into the divided reflectors 1, 2, 3,
When reflected at 4 respectively, as shown in FIG.
It becomes a spot pattern that spreads out in a substantially fan shape below.

In this spot pattern, the spot pattern 1'of the upper central reflector 1 and the spot pattern 4'of the lower reflector 4 are positioned so as to substantially overlap each other in the central portion, and the spot patterns 2'and 3'of the upper left and right reflectors 2 and 3 are located. Will be located on both sides. When the passing filament is on the vertical line V, the pattern is as shown in FIG. 3, but when the passing filament is shifted to the left or right of the vertical line V, the spots of the upper left and right reflectors are changed depending on the degree of the shift. The sizes of the patterns 2'and 3'are changed. For example, in the case of a headlamp of an automobile, the reflectors are arranged by slightly shifting the positions of the passing filaments between the left side mounting and the right side mounting. It is possible to obtain a desired light distribution pattern without changing the spot pattern of the passing filament by changing the incident angle to the light.

Next, the light distribution pattern of the traveling filament 6 will be described as a spot pattern as shown in FIG. Since the traveling filament 6 is located below the central axis X in the front direction of the reflector A and in front of the passing filament 5, the spot pattern 1'at the upper central reflector 1 is located below the horizontal line H. ,
The spot patterns 2'and 3'on the upper left and right reflectors 2 and 3 are located slightly to the left and right above the horizontal line H, and the spot patterns 4'on the lower reflector 4 are located.
Is a hot zone which is located slightly above the intersection of the horizontal line H and the vertical line V.

In the case of this traveling filament 6 as well, as in the case of the passing filament 5, the spot patterns of the upper left and right reflectors are slightly deformed by arranging them so that they are slightly shifted to the left and right depending on the position of use, and by adjusting the deformed state. Therefore, an appropriate light distribution pattern can be obtained.

In the first embodiment, the reflector is divided into four parts, but the same light distribution structure can be used in the six-part reflector structure of the second embodiment described below.

Next, the second embodiment shown in FIGS. 5 to 8 will be described. The same parts as those in the above-mentioned embodiment are designated by the same reference numerals and the detailed description thereof will be omitted.

The second embodiment is a case of a 6-division reflector, and a fifth embodiment
FIG. 6 is a schematic front view of the headlamp of the second embodiment, and FIG. 6 is a schematic enlarged cross-sectional view of the main part of the headlamp of FIG. 5 along the vertical line V, which is easy to understand. In order to do so, a horizontal line H divides the upper and lower reflectors.

Also in this embodiment, the upper part of the entire reflector A is divided into three reflectors, that is, the upper central reflector 1, the upper left reflector 2 and the upper right reflector 3 as in the first embodiment.

Like the upper reflector, the lower part of the entire reflector A of the second embodiment is divided substantially symmetrically from the center point B or the central portion C of the reflector A in the left and right diagonal downward directions.
The lower reflector is divided into three parts: a lower central reflector 40, a lower left reflector 7 and a lower right reflector 8. These six divided reflectors 1, 2, 3,
Reference numerals 40, 7 and 8 are each formed of a paraboloid of revolution as in the first embodiment.

In each of the lower reflectors 40, 7 and 8 in this case, the lower central reflector 40 is formed in the same manner as the lower reflector 4 of the first embodiment, and the lower left and right reflectors 7 and 8 are less than the lower central reflector 40. And the focal points f ₇ and f ₈ of the lower left and right reflectors 7 and 8 are on the same axis as the upper central reflector 1 and the upper and right reflectors 2 and 3, that is, on the central axis X of the reflector A. Alternatively, the focal points f ₇ and f ₈ of the lower left and right reflectors 7 and ₈ are located below the central axis X and in front of the focal point f ₄₀ of the lower central reflector.

Further, similarly to the upper reflector of the first embodiment, the focal length F ₄₀ of the lower central reflector 40 is made larger than the focal lengths F ₇ , F ₈ of the other lower left and right reflectors 7, ₈ .

In addition, the upper reflectors 1, 2, and 3 have the above-mentioned first
Since it is formed in the same manner as in the embodiment, the focal length F ₁ of the upper central reflector 1 is set to be larger than the focal lengths F ₂ , F ₃ of the upper left and right reflectors ₂ , ₃ and, as described in the first embodiment. Since F _1> F ₄ as, also in this second embodiment F _1>
F ₄₀ .

Therefore, the focal length of each reflector is F ₁ > F ₄₀ > F ₂ ,
It is formed to have a relationship of F ₃ , F ₇ , and F ₈ .

The traveling beam filament 6 and the passing beam filament 5 are arranged in the same manner as in the first embodiment, and the focal points f ₇ and f ₈ are near the focal point f ₄₀ of the lower central reflector 40 and at the center. It is formed so as to be on the X axis, which is slightly forward of the front end portion in the longitudinal direction of the traveling beam filament 6 located below the axis X. Further, in the case of the second embodiment, the amount of the traveling beam filament 6 protruding in front of the passing filament 5 is smaller than that in the case of the above-mentioned first embodiment, and is 0 to 1 mm.

The light distribution pattern obtained by the reflector having the above structure is as shown in FIGS. 7 and 8. FIG. 7 shows a case where the passing filament 5 is turned on, and the upper center reflector 1 and the lower center reflector 4 are shown.
And the spot patterns 1 ', 40' are located below the horizon H and partially overlap each other, and the spot patterns 2 ', 3'of the upper left and right reflectors 2, 3 are also located under the horizon H on the left and right. The spot patterns 7'and 8'of the lower left and right reflectors 7 and 8 are positioned so as to substantially overlap these spot patterns. In this case, the spot patterns 7 ', 8'of the lower central reflectors 7, 8'
Are radiated crossing each other, so in the overlap with the spot patterns of the upper left and right reflectors,
The spot pattern 2'of the upper left reflector 2 and the spot pattern 8'of the lower right reflector 8 overlap with each other, and the spot pattern 3'of the upper right reflector 3 and the spot pattern 7'of the lower left reflector 7 overlap.
And will overlap.

FIG. 8 is a light distribution pattern when the traveling filament 6 is lit, and the spot patterns 1 ′ and 40 ′ of the upper central reflector 1 and the lower central reflector 4 are
A part of them overlaps with each other over the horizontal line H, and the spot patterns 2 ', 3'of the left and right reflectors 2, 3 on the upper side are also almost over the horizontal line H, and are located in a state of being raised above the central part, The spot patterns 7 ', 8'of the lower left and right reflectors 7, 8 are positioned so as to overlap each other. Also in this case, similarly to the above, the reflected light from the lower central reflector is irradiated in a crossed manner, so that the spot patterns 2 ', 8'and the spot patterns 3', 8 '
7's overlap each other.

In any of the embodiments, it is possible to eliminate the dark part in the central part, weaken the brightness in front of the unnecessary road surface, and make it possible to obtain sufficient brightness in the distance range necessary for driving. I did.

〔The invention's effect〕

A horizontal line that passes or is vertically divided near the horizontal line, and the divided upper reflector is a vertical line that passes through the center point from the center point or the central portion near the center point to the left diagonally upward direction and the right diagonally upward direction. It is divided into three reflectors, an upper left reflector, an upper center reflector, and an upper right reflector so that they are substantially symmetrical about the line, and the reflector is an upper left reflector, an upper center reflector, an upper right reflector, and an upper right reflector. The lower part of the lower reflector is composed of four rotating paraboloids and is divided into four parts. The focal point of the object reflector is formed such that the focal length of the upper central reflector is longer than the focal lengths of the other paraboloidal rotating parabolic reflectors, and the focal point of the upper central reflector, the focal point of the upper left reflector and the upper right. The focus of the reflector is on the center axis in the front direction and behind the focus of the upper central reflector (reflector side), there are both focal points of the upper left and right reflectors, and the focal point of the lower reflector is more than the focal point of the upper central reflector. Separated by at least the length of the passing filament in the longitudinal direction, and
Of the reflectors formed below the central axis of the front direction, or further divided vertically into a horizontal line passing through the center point of the reflector or in the vicinity of the horizontal line, the lower reflector is left from the center point or the central portion. It is divided diagonally downward and diagonally rightward into left and right, and is divided into three symmetrical parabolic reflectors, a lower left reflector, a lower central reflector and a lower right reflector. The lower central reflector is the same as the lower reflector described above. The lower left and right reflectors are formed so that the focal lengths of both the left and right reflectors are shorter than the focal length of the lower central reflector, and the focal points of the left and right reflectors are on the front center axis. In addition, it is formed so as to be located in front of the focal point of the lower central reflector. According to the present invention, the reflector consisting of the compound parabolic reflector of the paraboloid of revolution of the present invention is divided into four or six, and the respective divided reflectors are located behind the filaments where the focal points of the above-mentioned respective reflectors are behind, Is formed so that the respective focal points of the respective reflectors are in front of the passing filaments, and the focal lengths of the respective divided reflectors are the same or partly changed, and the respective divided paraboloids of rotation are parabolic. Each of the reflectors is formed by combining the reflectors so that the reflection state of the reflector composed of the composite reflecting mirror, i.e., the spot pattern, can be adjusted to the most convenient light distribution pattern according to actual driving requirements. It has an excellent effect that the spot patterns can be combined. Further, in a vehicle headlamp having a reflector composed of the composite reflecting mirror, the passing filament includes a front central axis and a longitudinal direction of the filament between a focal point of the upper central reflector and a focal point of the lower reflector. Are arranged substantially parallel to each other and slightly above, and the traveling filament is such that the front center axis and the filament longitudinal direction are substantially parallel to each other so that the front end of the filament is located near the focal point of the lower reflector. The central axis of the running filament in the longitudinal direction is 0 from the front of a vertical line passing through the central axis of the passing filament and parallel to the vertical line. ~
By arranging a running filament of the same length as the passing filament at the maximum so as to be within the range of 45 °, no dark part is generated in the central part in the illuminating light no matter which filament is turned on. In addition to the above, it is possible to weaken the lighting in front of the road surface, which is not often required, and to increase the amount of light of the required lighting portion by that amount, which is an excellent effect.

Especially when the running filament is turned on, the light amount in the hot zone in the center increases and the visibility in the distance becomes great, so that the light distribution is easy to run, and when the passing filament is turned on, it is further ahead of the road surface. The front and both sides are brighter, the visibility is great, and it has various excellent effects such as light distribution that is also easy to run, and it also makes a significant difference in the feeling of switching between the running beam and the passing beam, switching It also has the effect of giving a feeling.
