Description

The present invention relates to a vehicle lamp, and in particular, when the front lens body is visually recognized from the front, a feeling of division occurs in the front lens body, and it is possible to suppress the appearance of the line shape of the front lens body from being impaired. Regarding lighting equipment.

Conventionally, the front lens portion, the rear lens portion arranged behind the rear lens portion, and the rear lens portion are arranged behind the rear lens portion, and the light is transmitted to the front through the rear lens portion and the front lens portion in this order and irradiated forward to distribute light for a head lamp. A vehicle lamp equipped with a light source that emits light forming a pattern is known (see, for example, Patent Document 1 (FIG. 36, etc.)). The rear lens unit is a lens unit responsible for condensing light in the first direction (for example, a direction inclined by a predetermined angle with respect to a reference axis extending in the vehicle width direction), and the front lens unit is a second direction orthogonal to the first direction. This is the lens unit that is in charge of condensing light.

On the other hand, as shown in FIG. 8, the present inventors have a plurality of rears arranged adjacent to each other along a predetermined direction behind the front lens body 100 (front lens portion) extending in a predetermined direction. It was examined to integrally form the rear lens body 103 including the lens portion 101 and the connecting portion 102 that connects the rear lens portions 101 arranged adjacent to each other by, for example, injection molding. FIG. 8 is a sectional view taken along the line AA of the vehicle lamp 10A shown in FIG. FIG. 9 is a front view (light source omitted) of the vehicle lamp 10A using the front lens body 100 and the rear lens body 103 shown in FIG.

At that time, from the viewpoint of reducing the material cost, it was considered to shorten the length LB (see FIGS. 8 and 10 (b)) along the reference axis AX _Lo extending in the vehicle front-rear direction of the connecting portion 102.

International Publication No. 2015/178155

However, as a result of the study by the present inventors, when the length LB of the connecting portion 102 is shortened, as shown in FIG. 10, when the front lens body 100 is visually recognized from the front, the direction of the line of sight transmitted through the front lens body 100 is obtained. The front lens body 100 has a large difference between the distance LA through which the light RayA passes through the rear lens portion 101 and the distance LB through which the light RayB in the line-of-sight direction transmitted through the front lens body 100 passes through the connecting portion 102. It has been found that a feeling of division occurs and the linear appearance of the front lens body 100 is impaired.

Hereinafter, this point will be described in detail.

This is a region where the distance through which the light RayB in the line-of-sight direction transmitted through the connecting portion 102 is transmitted through the connecting portion 102 is LB.

In this way, when the front lens body 100 is visually recognized from the front of the front lens body 100, the light RayA in the line-of-sight direction that has passed through the front lens body 100 has passed through the distance LA that passes through the rear lens portion 101 and the front lens body 100. The light Ray B in the line-of-sight direction is significantly different from the distance LB transmitted through the connecting portion 102. Due to this, when the front lens body 100 is visually recognized from the front of the front lens body 100, the appearance of the first region A1a and the second region A2a is different.

As a result, when the front lens body 100 is visually recognized from the front, as shown in FIG. 11, a feeling of division occurs in the front lens body 100, and the linear appearance of the front lens body 100 is impaired.

FIG. 1 is a perspective view of a vehicle lamp 10. FIG. 2 is a front view of the vehicle lamp 10.

The vehicle lighting fixtures 10 shown in FIGS. 1 and 2 are vehicle headlamps, and are mounted on the left and right sides of the front end of a vehicle such as an automobile, respectively. Since the vehicle lighting fixtures 10 mounted on both the left and right sides have a symmetrical configuration, the vehicle lighting fixtures 10 mounted on the left side of the front end portion of the vehicle (the left side when facing the front of the vehicle) will be described below as a representative. .. Although not shown, the vehicle lighting fixture 10 is arranged in a lighting chamber composed of an outer lens and a housing, and is attached to the housing or the like.

FIG. 3 is a sectional view taken along the line AA of the vehicle lamp 10 shown in FIG.

As shown in FIG. 3, the vehicle lighting equipment 10 includes a front lens body 20 extending in a predetermined direction, and a plurality of rear lens portions 31A to be arranged behind the front lens body 20 so as to be adjacent to each other along a predetermined direction. A rear lens body 30 including 31C, first connecting portions 32A to 32B for connecting rear lens portions arranged adjacent to each other, and a rear lens provided behind a plurality of rear lens portions 31A to 31C. It includes a plurality of light sources 40A to 40C that transmit light that passes through the portions 31A to 31C and the front lens body 20 in this order and is irradiated forward to form a light distribution pattern for a low beam. The first connecting portions 32A to 32B correspond to the connecting portions of the present invention, and the low beam light distribution pattern corresponds to the predetermined light distribution pattern of the present invention.

The front lens body 20 and the rear lens body 30 are made of a transparent resin such as acrylic or polycarbonate, and are integrally molded by injection molding.

Since the rear lens portions 31A to 31C, the first connecting portions 32A to 32B, and the light sources 40A to 40C have the same configuration, they are described below as the rear lens portion 31, the first connecting portion 32, and the light source 40, unless these are particularly distinguished. do.

The front lens body 20 is a lens portion extending in a predetermined direction (hereinafter, also referred to as a first direction). For example, as shown in FIG. 3, the predetermined direction is tilted by a receding angle θ1 with respect to the reference axis AX1 extending in the vehicle width direction in the top view, and is in the vehicle width direction in the front view as shown in FIG. It is a direction inclined by a hanging eye angle θ2 with respect to the reference axis AX1 extending to. FIG. 4 is a view (front view of the vehicle lamp 10) for explaining the hanging eye angle θ2. θ1 and θ2 are arbitrary angles within 0 to 90 degrees, respectively. FIG. 2 is an example when the hanging eye angle θ2 is 0 degrees.

As shown in FIG. 3, the front lens body 20 includes a second light entering surface 21 extending in the first direction and a second light emitting surface 22 extending in the first direction on the opposite side thereof.

The second light entrance surface 21 is, for example, a flat surface (for example, a vertical surface). The second light emitting surface 22 is a semicircular column whose columnar axis extends in the first direction in order to collect the light emitted from the rear lens portion 31 emitted from the second light emitting surface 22 in the second direction orthogonal to the first direction. It is configured as a surface (cylindrical surface).

As shown in FIG. 2, the front lens body 20 includes a first region A1 and a second region A2 that are visible from the front of the front lens body 20.

In the first region A1, as shown in FIG. 5A, when the front lens body 20 is visually recognized from the front of the front lens body 20, the light Ray1 in the line-of-sight direction transmitted through the first region A1 is directed to the rear lens portion 31. This is the area where light enters. The distance that the light Ray1 in the line-of-sight direction that has passed through the first region A1 passes through the rear lens body 30 (rear lens portion 31) is L1.

Here, the optical Ray 1 is light that coincides with the optical axis of the light distribution emitted from the second light emitting surface 22 when the light source 40 emits light, and is directed toward the front lens body 20 in the opposite direction. For example, the optical Ray 1 travels from the front of the front lens body 20 along the reference axis AX _Lo (see FIGS. 3 and 5A), passes through the front lens body 20, and then enters the rear lens portion 31. It is the light to do.

In the second region A2, as shown in FIG. 5B, when the front lens body 20 is visually recognized from the front of the front lens body 20, the light Ray 2 in the line-of-sight direction transmitted through the second region A2 is the first connecting portion 32. This is the area where the light enters. The distance that the light Ray 2 in the line-of-sight direction transmitted through the second region A2 passes through the rear lens body 30 (first connecting portion 32, etc.) is such that the light Ray 2 in the line-of-sight direction is totally reflected by the rear surface 35 of the first connecting portion 32. By changing the traveling direction of the light Ray2 in the line-of-sight direction, L2 + α is obtained. This point will be described later.

FIG. 5A is a sectional view taken along the line BB of the vehicle lamp 10 shown in FIG.

As shown in FIG. 5A, the front lens body 20, the rear lens unit 31, and the light source 40 form a low beam optical system.

In general vehicle lighting equipment, one projection lens is in charge of condensing light in the first direction and condensing light in the second direction orthogonal to the first direction, whereas in the present embodiment, two lens units ( The front lens body 20 and the rear lens unit 31) are in charge of condensing light in the first direction and condensing light in the second direction orthogonal to the first direction. That is, in the present embodiment, the rear lens unit 31 is in charge of condensing light in the first direction, and the front lens body 20 is in charge of condensing light in the second direction.

The light source 40 transmits light that passes through the rear lens portion 31 and the front lens body 20 in this order and is irradiated forward to form a low beam light distribution pattern. Specifically, the light source 40 is a semiconductor light emitting element such as an LED or LD having a rectangular (for example, 1 mm square) light emitting surface, and is mounted on the substrate K1 with the light emitting surface facing forward (front). .. The substrate K1 is attached to a housing (not shown) or the like by screwing or the like.

The rear lens portion 31 has an edge portion 31c and an edge provided between the first light incoming surface 31a, the first light emitting surface 31b on the opposite side thereof, and the first light entering surface 31a and the first light emitting surface 31b. It includes a reflecting surface 31d extending rearward from the portion 31c and an extending surface 31e extending downward from the edge portion 31c.

The light from the light source 40 that has entered the rear lens portion 31 from the first incoming light surface 31a is focused toward the edge portion 31c at least in the vertical direction (upper and lower directions in FIG. 5A). As a result, the low beam light distribution pattern becomes relatively bright near the cut-off line.

The first light emitting surface 31b is, for example, a semi-cylindrical surface (cylindrical surface) in which the cylindrical axis extends in the second direction in order to collect the light emitted from the light source 40 emitted from the first light emitting surface 31b in the first direction. ).

The edge portion 31c is configured to have a shape corresponding to the cut-off line of the low beam light distribution pattern. Although not shown, the edge portion 31c has, for example, a Z-shaped step portion.

The front lens body 20 and the rear lens portion 31 are connected by a second connecting portion 33. The second connecting portion 33 connects the upper portion of the front lens body 20 and the upper portion of the rear lens portion 31 with a space S1 sandwiched between them.

FIG. 5B is a sectional view taken along the line CC of the vehicle lamp 10 shown in FIG.

As shown in FIG. 5B, the first connecting portion 32 includes a front surface 34 and a rear surface 35 on the opposite side thereof.

The front lens body 20 and the first connecting portion 32 are connected by a third connecting portion 36. The third connecting portion 36 connects the upper portion of the front lens body 20 and the upper portion of the first connecting portion 32 with a space S2 sandwiched between them. The third connecting portion 36 and the second connecting portion 33 shown in FIG. 5A are continuous. Similarly, the space S2 and the space S1 shown in FIG. 5A are continuous.

The length L2 (see FIGS. 3 and 5B) along the reference axis AX _Lo extending in the vehicle front-rear direction of the first connecting portion 32 is such that the light Ray1 in the line-of-sight direction transmitted through the first region A1 is a rear lens body. It is shorter than the distance L1 (see FIG. 5A) transmitted through 30 (rear lens portion 31). The length L2 is, for example, 3 mm or more.

As shown in FIG. 5B, the first connecting portion 32 includes an optical surface that changes the traveling direction of the light Ray 2 in the line-of-sight direction that has passed through the front lens body 20 and entered the first connecting portion 32. This optical surface is, for example, the rear surface 35 of the first connecting portion 32.

Here, the light Ray 2 is light obtained by moving the light Ray 1 to a position incident on the first connecting portion 32 along the first direction in which the fishing angle θ2 is tilted. For example, the optical Ray 2 travels from the front surface of the front lens body 20 along the reference axis AX ₃₂ (see FIGS. 3 and 5B), passes through the front lens body 20, and then enters the first connecting portion 32. It is a shining light. The reference axis AX ₃₂ passes through the first connecting portion 32 in parallel with the reference axis AX _Lo .

The rear surface 35 is an inclined surface that changes the traveling direction of the light Ray 2 in the line-of-sight direction by totally reflecting the light Ray 2 in the line-of-sight direction that has passed through the front lens body 20 and entered the first connecting portion 32.

Specifically, the rear surface 35 is a front lens so that when the front lens body 20 is visually recognized from the front of the front lens body 20, the first region A1 and the second region A2 shown in FIG. 2 have the same appearance. The traveling direction of the light Ray 2 in the line-of-sight direction that has passed through the second region A2 from the front surface of the body 20 and entered the first connecting portion 32 is changed.

For example, the rear surface 35 has a distance L2 + α (see FIG. 5B) through which the light Ray2 in the line-of-sight direction transmitted through the second region A2 passes through the rear lens body 30 (first connecting portion 32 and the like) and the first region A1. The front lens body is in the direction F (see FIG. 5 (b)) in which the transmitted light Ray 1 in the line-of-sight direction is equal to the distance L1 (see FIG. 5 (a)) transmitted through the rear lens body 30 (rear lens portion 31). The traveling direction of the light Ray 2 in the line-of-sight direction that has passed through the second region A2 from the front surface of the 20 and entered the first connecting portion 32 is changed. That is, the rear surface 35 is tilted so as to totally reflect the light Ray2 in the line-of-sight direction that has passed through the second region A2 and entered the first connecting portion 32 toward the direction F (see FIG. 5B). It is provided at. The angle of the rear surface 35 with respect to the reflection surface 31d is larger than the angle of the extension surface 31e with respect to the reflection surface 31d, and the rear surface 35 is a surface inclined more than the extension surface 31e. The portion indicated by reference numeral 37 in FIG. 5B is a flange portion used when the front lens body 20 and the rear lens body 30 are attached to a housing (not shown) or the like.

In FIG. 5B, the traveling direction of the light Ray2 in the line-of-sight direction that enters the first connecting portion 32 is changed to the upward direction, but the traveling direction is not limited to this, but the downward direction, the left-right direction, and other directions. May be changed to. The front surface 34 has a surface shape in which the light Ray 2 is refracted upward so that the rear surface 35 can easily reflect upward. The rear surface 35 is an inclined surface that is inclined upward, while the front surface 34 is an inclined surface that is inclined downward in the opposite direction. Even when the rear surface 35 changes the traveling direction of the optical Ray 2 in the downward direction, the left-right direction, or the other direction, the front surface 34 preferably has a surface shape that bends with respect to the changing direction.

In this way, the light Ray2 in the line-of-sight direction that has passed through the second region A2 has passed through the distance L2 + α (see FIG. 5B) that has passed through the rear lens body 30 (first connecting portion 32 and the like) and the first region A1. The front lens body 20 was visually recognized from the front by making the light Ray 1 in the line-of-sight direction equal to (or substantially equal to) the distance L1 (see FIG. 5A) transmitted through the rear lens body 30 (rear lens unit 31). In this case, the first region A1 and the second region A2 can be viewed in the same manner.

As a result, when the front lens body 20 is visually recognized from the front, as shown in FIG. 6, it is possible to prevent the front lens body 20 from being divided and the linear appearance of the front lens body 20 from being impaired. can. FIG. 6 is a front view (photograph) of the front lens body 20 in which the feeling of division is suppressed.

In the low beam optical system having the above configuration, when the light source 40 is turned on, the light from the light source 40 enters the rear lens portion 31 from the first light incoming surface 31a and is partially shielded by the reflecting surface 31d. Light is emitted from the first light emitting surface 31b together with the reflected light from the reflecting surface 31d. At that time, the light from the light source 40 emitted from the first light emitting surface 31b is focused in the first direction by the action of the first light emitting surface 31b. Then, the light emitted from the light source 40 emitted from the first light emitting surface 31b passes through the space S1 between the rear lens unit 31 and the front lens body 20, and further, the front lens body 20 from the second light entering surface 21. Light enters the lens and emits light from the second light emitting surface 22 to be irradiated forward. At that time, the light from the light source 40 emitted from the second light emitting surface 22 is collected in the second direction by the action of the second light emitting surface 22. As a result, a low beam light distribution pattern is formed.

In other words, the luminous intensity distribution formed in the vicinity of the edge portion 31c by the light from the light source 40 that has entered the rear lens portion 31 functions as a projection lens for the rear lens portion 31 (first light emitting surface 31b) and the front lens body. It is inverted and projected forward by 20. As a result, a low beam light distribution pattern is formed.

FIG. 7 is an example of the low beam light distribution pattern P _Lo . FIG. 7 shows an example of a low beam light distribution pattern P _Lo formed on a virtual vertical screen (arranged about 25 m ahead of the vehicle front) facing the front of the vehicle. The low beam light distribution pattern P _Lo includes a cut-off line CL defined by the edge portion 31c at the upper end edge.

As described above, according to the present embodiment, when the front lens body 20 is visually recognized from the front, a feeling of division occurs in the front lens body 20 and it is suppressed that the linear appearance of the front lens body 20 is impaired. It is possible to provide a vehicle lamp 10 that can be used (for example, when the light source 40 is not lit).

This is an optical surface on which the first connecting portion 32 changes the traveling direction of the light Ray 2 in the line-of-sight direction that has passed through the front lens body 20 from the front surface of the front lens body 20 and entered the first connecting portion 32. This is due to the provision of 35.

Specifically, when the rear surface 35 visually recognizes the front lens body 20 from the front of the front lens body 20, the front lens has the same appearance in the first region A1 and the second region A2 shown in FIG. This is due to changing the traveling direction of the light Ray 2 in the line-of-sight direction that has passed through the second region A2 from the front surface of the body 20 and entered the first connecting portion 32.

As a result, when the front lens body 20 is visually recognized from the front, it is possible to prevent the front lens body 20 from being divided and the linear appearance of the front lens body 20 from being impaired.

Next, a modification will be described.

In the above embodiment, the light Ray 2 in the line-of-sight direction that has passed through the front lens body 20 from the front surface of the front lens body 20 and entered the first connecting portion 32 is totally reflected by the rear surface 35 of the first connecting portion 32. An example of changing the traveling direction of the light Ray 2 in the line-of-sight direction has been described, but the present invention is not limited to this.

For example, by refracting the light Ray 2 in the line-of-sight direction that has passed through the front lens body 20 from the front surface of the front lens body 20 and entered the first connecting portion 32 at the front surface 34 of the first connecting portion 32, the light in the line-of-sight direction is refracted. The traveling direction of Ray 2 may be changed.

Further, in the above embodiment, an example in which a front lens body provided with a semi-cylindrical surface (cylindrical surface) is used as the front lens body 20 has been described, but the present invention is not limited to this. For example, a so-called transparent outer lens may be used as the front lens body 20.

An example using a cylindrical surface) has been described, but the present invention is not limited to this.

For example, a semi-cylindrical surface (cylindrical surface) whose columnar axis extends in the first direction is used as the second light incoming surface 21 of the front lens body 20, and a flat surface (for example, a vertical surface) is used as the second light emitting surface 22. You may.
