Description

  The present invention relates to a vehicular lamp, and in particular, when a front lens body is viewed from the front, the front lens body has a feeling of partitioning, and a vehicle that can suppress the deterioration of the line-like appearance of the front lens body. It relates to a lamp.

  Conventionally, a front lens unit, a rear lens unit disposed behind the front lens unit, and a rear lens unit are disposed behind the rear lens unit, and are transmitted through the rear lens unit and the front lens unit in this order to be irradiated in front and distributed for headlamps. There is known a vehicular lamp including a light source that emits light that forms a pattern (see, for example, Patent Document 1 (FIG. 36, etc.)). The rear lens unit is a lens unit in charge of condensing light in a first direction (for example, a direction inclined at a predetermined angle with respect to a reference axis extending in the vehicle width direction), and the front lens unit is in a second direction orthogonal to the first direction. It is a lens part in charge of condensing.

  On the other hand, as shown in FIG. 8, the present inventors have a plurality of rear portions arranged adjacent to each other along the predetermined direction behind the front lens body 100 (front lens portion) extending in the predetermined direction. It has been studied 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, for example, by injection molding. 8 is a cross-sectional view taken along line AA of the vehicular lamp 10A shown in FIG. FIG. 9 is a front view (light source omitted) of the vehicular 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 10B) of the connecting portion 102 along the reference axis AX _Lo extending in the vehicle front-rear direction.

International Publication No. 2015/178155

  However, as a result of studies 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 viewed from the front, the direction of the line of sight passing through the front lens body 100 is reduced. Due to the large difference between the distance LA where the light RayA is transmitted through the rear lens portion 101 and the distance LB where the light RayB transmitted through the front lens body 100 is transmitted through the connecting portion 102, It has been found that a feeling of separation occurs and the line-like appearance of the front lens body 100 is impaired.

  Hereinafter, this point will be described in detail.

The distance LB through which the light RayB in the eye direction passes through the connecting portion 102 is greatly different. Due to this, when the front lens body 100 is viewed from the front of the front lens body 100, the first region A1a and the second region A2a are different in appearance.

  As a result, when the front lens body 100 is viewed from the front, as shown in FIG. 11, the front lens body 100 is divided and the appearance of the line shape of the front lens body 100 is impaired.

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

  A vehicle lamp 10 shown in FIGS. 1 and 2 is a vehicle headlamp (head lamp), and is mounted on each of the left and right sides of a front end portion of a vehicle such as an automobile, for example. Since the vehicular lamp 10 mounted on both the left and right sides has a symmetrical configuration, the vehicular lamp 10 mounted on the left side of the front end of the vehicle (left side toward the front of the vehicle) will be described as a representative. . Although not shown, the vehicular lamp 10 is disposed in a lamp chamber composed of an outer lens and a housing, and is attached to the housing or the like.

  3 is a cross-sectional view of the vehicular lamp 10 shown in FIG.

  As shown in FIG. 3, the vehicular lamp 10 includes a front lens body 20 extending in a predetermined direction, and a plurality of rear lens portions 31 </ b> A to 31 </ b> A disposed adjacent to each other along the predetermined direction behind the front lens body 20. A rear lens body 30 including 31C and first connecting portions 32A to 32B that connect rear lens portions disposed adjacent to each other, and a rear lens provided behind the plurality of rear lens portions 31A to 31C. And a plurality of light sources 40A to 40C that emit 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 low beam. The first connecting portions 32A to 32B correspond to 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 formed 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, the following description will be made as the rear lens portion 31, the first connecting portion 32, and the light source 40 unless they are particularly distinguished. To 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 inclined by a receding angle θ1 with respect to a reference axis AX1 extending in the vehicle width direction in a top view, and in the vehicle width direction in a front view as shown in FIG. 4. The tilt angle θ2 is inclined with respect to the reference axis AX1 extending in the direction. FIG. 4 is a diagram (a front view of the vehicular lamp 10) for explaining the transition angle θ2. θ1 and θ2 are each an arbitrary angle within 0 to 90 degrees. FIG. 2 shows an example in which the transition angle θ2 is 0 degree.

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

  The second light incident surface 21 is, for example, a flat surface (for example, a vertical surface). The second light exit surface 22 condenses the light from the rear lens portion 31 that exits from the second light exit surface 22 in a second direction orthogonal to the first direction, so that the cylinder axis extends in the first direction. It is comprised as a surface (cylindrical surface).

  As shown in FIG. 2, the front lens body 20 includes a first area A <b> 1 and a second area A <b> 2 that are visible from the front of the front lens body 20.

  5A, when the front lens body 20 is viewed from the front of the front lens body 20, the first area A1 has the light ray 1 in the line of sight transmitted through the first area A1 in the rear lens portion 31. This is the area where light enters. The distance through which the light ray 1 in the eye line direction that has passed through the first region A1 passes through the rear lens body 30 (the rear lens portion 31) is L1.

Here, the light Ray1 is light that coincides with the optical axis of the light distribution emitted from the second light exit surface 22 when the light source 40 emits light and travels toward the front lens body 20 in the opposite direction. For example, the light Ray 1 travels along the reference axis AX _Lo (see FIGS. 3 and 5A) from the front of the front lens body 20, passes through the front lens body 20, and then enters the rear lens unit 31. It is light to do.

  As shown in FIG. 5B, in the second area A2, when the front lens body 20 is viewed from the front of the front lens body 20, the light ray 2 in the line-of-sight direction transmitted through the second area A2 is the first connecting portion 32. This is the area where light enters. The distance that the light ray 2 in the line-of-sight direction that has passed through the second region A2 passes through the rear lens body 30 (the first coupling part 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 coupling part 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.5 (a) is BB sectional drawing 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 constitute a low beam optical system.

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

  The light source 40 emits light that passes through the rear lens unit 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 unit 31 includes a first light incident surface 31a, an opposite first light output surface 31b, an edge portion 31c provided between the first light incident surface 31a and the first light output surface 31b, an edge A reflecting surface 31d extending rearward from the portion 31c and an extending surface 31e extending downward from the edge portion 31c are included.

  The light from the light source 40 that has entered the rear lens portion 31 from the first light incident surface 31a is condensed toward the edge portion 31c at least in the vertical direction (the vertical direction in FIG. 5A). Thereby, the light distribution pattern for low beam becomes relatively bright in the vicinity of the cut-off line.

  The first light exit surface 31b is, for example, a semi-cylindrical surface (cylindrical surface) having a cylindrical axis extending in the second direction in order to condense light from the light source 40 that exits from the first light exit surface 31b in the first direction. ).

  The edge part 31c is configured in 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 2nd connection part 33 has connected the upper part of the front lens body 20, and the upper part of the back lens part 31 in the state which pinched | interposed space S1 between both.

  FIG.5 (b) is CC sectional drawing 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.

  The front lens body 20 and the first connecting part 32 are connected by a third connecting part 36. The 3rd connection part 36 has connected the upper part of the front lens body 20, and the upper part of the 1st connection part 32 in the state which pinched | interposed space S2 between both. The 3rd connection part 36 and the 2nd connection part 33 shown to Fig.5 (a) are continuing. Similarly, the space S2 and the space S1 shown in FIG. 5A are continuous.

The length L2 (see FIGS. 3 and 5B) of the first connecting portion 32 along the reference axis AX _Lo extending in the vehicle front-rear direction is such that the light ray 1 in the eye direction transmitted through the first region A1 is the rear lens body. 30 (rear lens portion 31) is shorter than the distance L1 (see FIG. 5A). The length L2 is 3 mm or more, for example.

  As shown in FIG. 5B, the first connecting portion 32 includes an optical surface that changes the traveling direction of the light Ray2 in the eye direction that has passed through the front lens body 20 and entered the first connecting portion 32. This optical surface is the rear surface 35 of the 1st connection part 32, for example.

Here, the light Ray2 is a light obtained by moving the light Ray1 along the first direction inclined at the fish angle θ2 to the position where the light Ray1 is incident on the first connecting portion 32. For example, the light Ray 2 travels along the reference axis AX ₃₂ (see FIGS. 3 and 5B) from the front of the front lens body 20, passes through the front lens body 20, and then enters the first connecting portion 32. Light that shines. Note that the reference axis AX ₃₂ is parallel to the reference axis AX _Lo and passes through the first connecting portion 32.

  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, when the front lens body 20 is viewed from the front of the front lens body 20, the rear surface 35 is configured so that the first area A1 and the second area A2 shown in FIG. The traveling direction of the light Ray2 in the eye-line direction that has passed through the second region A2 from the front 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 transmitted through the second region A2 passes through the rear lens body 30 (the first coupling portion 32 and the like) and the first region A1. The front lens body in a direction F (see FIG. 5 (b)) in which the distance L1 (see FIG. 5 (a)) through which the transmitted ray Ray1 in the line of sight passes through the rear lens body 30 (rear lens portion 31) is equal. The traveling direction of the light ray 2 in the line-of-sight direction that has passed through the second region A2 and entered the first connecting portion 32 from the front surface 20 is changed. That is, the rear surface 35 is inclined so as to totally reflect the light ray 2 in the eye-line direction that has passed through the second region A2 and entered the first connecting portion 32 toward the direction F (see FIG. 5B). Is provided. The angle of the rear surface 35 with respect to the reflective surface 31d is larger than the angle of the extended surface 31e with respect to the reflective surface 31d, and the rear surface 35 is inclined with respect to the extended surface 31e. In addition, the part which the code | symbol 37 in FIG.5 (b) shows is a flange part used when attaching the front lens body 20 and the back lens body 30 to a housing (not shown).

  In addition, in FIG.5 (b), although the advancing direction of the light Ray2 of the line-of-sight direction which entered the 1st connection part 32 is changed to the upper direction, it is not restricted to this, A downward direction, the left-right direction, and other directions You may change to The front surface 34 has a surface shape in which the light Ray2 is refracted upward so that the rear surface 35 can be easily reflected upward. The rear surface 35 is an inclined surface inclined upward, whereas the front surface 34 is a reverse inclined surface facing downward. Even when the rear surface 35 changes the traveling direction of the light Ray2 in the downward direction, the left-right direction, and other directions, the front surface 34 preferably has a surface shape that is refracted in the changing direction.

  In this way, the light ray 2 in the eye line direction that has passed through the second area A2 has passed through the first area A1 and the distance L2 + α (see FIG. 5B) that passes through the rear lens body 30 (the first connecting portion 32, etc.). The front lens body 20 was viewed from the front by making the distance L1 (see FIG. 5A) through which the light Ray1 in the line of sight passes through the rear lens body 30 (the rear lens portion 31) equal (or substantially equal). In this case, the first area A1 and the second area A2 can be viewed in the same manner.

  As a result, when the front lens body 20 is viewed from the front, as shown in FIG. 6, the front lens body 20 has a feeling of partitioning, and the line-like appearance of the front lens body 20 is prevented from being impaired. it can. FIG. 6 is a front view (photograph) of the front lens body 20 in which the feeling of separation 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 unit 31 from the first light incident surface 31a and is partially blocked by the reflecting surface 31d. The light exits from the first light exit surface 31b together with the reflected light from the reflective surface 31d. At that time, the light from the light source 40 that is emitted from the first light exit surface 31b is condensed in the first direction by the action of the first light exit surface 31b. Then, the light from the light source 40 emitted from the first light exit surface 31 b passes through the space S <b> 1 between the rear lens unit 31 and the front lens body 20, and further from the second light incident surface 21 to the front lens body 20. Is incident on the second light exit surface 22 and irradiated forward. At this time, the light from the light source 40 that is emitted from the second light exit surface 22 is condensed in the second direction by the action of the second light exit surface 22. Thereby, 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 incident on the rear lens portion 31 is the rear lens portion 31 (first light exit surface 31b) and the front lens body that function as a projection lens. 20 reversely projects forward. Thereby, a low beam light distribution pattern is formed.

FIG. 7 is an example of a low beam light distribution pattern _PLo . FIG. 7 shows an example of a low beam light distribution pattern P _Lo formed on a virtual vertical screen (disposed approximately 25 m forward from the front of the vehicle) 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 viewed from the front, the front lens body 20 has a feeling of partitioning, and the appearance of the line shape of the front lens body 20 is prevented from being impaired. The vehicular lamp 10 can be provided (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 entered the first connecting portion 32 through the front lens body 20 from the front of the front lens body 20. 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 first lens A1 and the second region A2 shown in FIG. This is by changing the traveling direction of the light ray 2 in the eye direction that has passed through the second region A2 from the front 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 suppress the front lens body 20 from having a feeling of partitioning and damaging the line-like appearance of the front lens body 20.

  Next, a modified example will be described.

  In the above embodiment, the light ray 2 in the line-of-sight direction transmitted through the front lens body 20 from the front of the front lens body 20 and entering the first connection portion 32 is totally reflected by the rear surface 35 of the first connection portion 32. Although the example which changes the advancing direction of light Ray2 of a sight line direction was demonstrated, it is not restricted to this.

  For example, the light ray 2 in the line-of-sight direction that has passed through the front lens body 20 from the front of the front lens body 20 and entered the first connection part 32 is refracted by the front surface 34 of the first connection part 32, thereby The traveling direction of Ray2 may be changed.

  Moreover, although the said embodiment demonstrated the example using the front lens body provided with the semi-cylindrical surface (cylindrical surface) as the front lens body 20, it is not restricted to this. For example, a so-called plain outer lens may be used as the front lens body 20.

  In the above embodiment, a flat surface (for example, a vertical surface) is used as the second light incident surface 21 of the front lens body 20, and a semi-cylindrical surface whose cylindrical axis extends in the first direction as the second light exit surface 22 ( Although an example using a cylindrical surface) has been described, the present invention is not limited to this.

  For example, a semi-cylindrical surface (cylindrical surface) whose cylindrical axis extends in the first direction is used as the second light incident surface 21 of the front lens body 20, and a flat surface (for example, a vertical surface) is used as the second light exit surface 22. May be.

  Moreover, although the said embodiment demonstrated the example using the semi-cylindrical surface (cylindrical surface) in which the cylinder axis extended to the 2nd direction as the 1st light emission surface 31b of the back lens part 31, it does not restrict to this.

  For example, a convex lens surface that is convex toward the front of the vehicle may be used as the first light exit surface 31 b of the rear lens unit 31.

  Moreover, although the said embodiment demonstrated the example using the back lens part for low beam light distribution patterns as the back lens part 31, it is not restricted to this.

  For example, as the rear lens unit 31, a rear lens unit for a light distribution pattern for ADB may be used, or a rear lens unit for a light distribution pattern for high beam may be used.

  Moreover, although this embodiment demonstrated the example which applied the vehicle lamp of this invention to the vehicle headlamp (headlamp), it is not restricted to this. For example, the vehicular lamp of the present invention may be applied to a vehicular lamp other than the vehicular headlamp (headlamp).

  All the numerical values shown in the above embodiment are exemplifications, and it is needless to say that appropriate numerical values different from these can be used.

  The above embodiment is merely an example in all respects. The present invention is not construed as being limited by the description of the above embodiment. The present invention can be implemented in various other forms without departing from the spirit or main features thereof.
