DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the accompanying drawings.
In description of embodiment, the same number is attached | subjected to the same element through the whole.
In this specification, front, rear, upper, lower, left, and right indicate directions viewed from a driver who rides on the vehicle when the vehicular lamp is mounted on the vehicle.

The vehicular lamp according to the embodiment of the present invention is a vehicular lamp (101R, 101L) provided on the left and right in front of the vehicle 102 shown in FIG. 1, and the configuration of the left and right vehicular lamps (101R, 101L) is left and right. Since it is symmetrical, only the right vehicle lamp 101R will be described below.
Hereinafter, the vehicle lamp 101R is referred to as a “vehicle lamp”.

(Overall configuration of vehicle lamp)
The vehicle lamp of the present embodiment is shown in FIG. 2 in a lamp chamber formed by a housing (not shown) that is open on the front side of the vehicle and an outer lens (not shown) that is provided so as to cover the opening of the housing. A lamp unit 10 is arranged.

(Lamp unit)
2 is a front view of the lamp unit 10, and FIG. 3 is a plan view of the lamp unit 10 as viewed from above.
As shown in FIG. 2, in the present embodiment, a lens 20 is used in which a cylindrical lens 21 arranged on the vehicle outer side and a projection lens 22 arranged on the vehicle center side are integrally formed.
In the lens 20, the flange portion 23 of the lens 20 is fixed to a lens holder 24 (see FIG. 3) attached to the heat sink 30 by a retainer 25.

  As shown in FIG. 3, the base part 31 of the heat sink 30 has a first reflector 40 that covers the first light source 43 in a semi-dome shape from above and a second reflector that covers the second light source 53 in a semi-dome shape from above. 50 are fixed with screws.

(light source)
The first light source 43 and the second light source 53 shown in FIG. 3 are both semiconductor-type light sources. For example, an LED, an EL (organic EL), or the like is formed on the substrates 41 and 51 on which a power supply pattern or the like (not shown) is formed. Self-luminous semiconductor light emitting elements 42 and 52 are mounted.

The number and shape of the semiconductor light emitting elements 42 and 52 used for forming the light emitting portion are not particularly limited. For example, a plurality of square semiconductor light emitting elements 42 and 52 are horizontally arranged on the substrates 41 and 51. The light emitting surface may be formed in a flat rectangular shape as a whole, or the light emitting surface may be formed by providing only one semiconductor light emitting element 42 or 52 having a square or rectangular shape. .
Further, the semiconductor light emitting elements 42 and 52 may be sealed with a sealing resin and packaged.

(Reflector)
As shown in FIG. 3, the first reflector 40 is disposed so as to cover the first light source 43 in a semi-dome shape so that the reflection surface of the reflection portion 40 a faces the first light source 43.
Similarly, the second reflector 50 is also arranged so as to cover the second light source 53 in a semi-dome shape so that the reflecting surface of the reflecting portion 50 a faces the second light source 53.
As can be seen from FIG. 3, the first reflector 40 and the second reflector 50 are provided at substantially the same position in the vehicle longitudinal direction.

Furthermore, the vehicle outer side of the first reflector 40 is fixed to the base portion 31 so as to be located slightly on the vehicle rear side from the vehicle center side.
More specifically, the axis perpendicular to the light reflection direction of the first reflector 40 is disposed so as to be inclined about 5 ° toward the vehicle rear side with respect to the axis in the vehicle width direction (horizontal direction). The light from the light source 43 is reflected toward the front slightly outside the vehicle.

  The first reflector 40 and the second reflector 50 are both reflecting surfaces whose reflecting surfaces (40a, 50a) are based on an ellipse. More specifically, the reflecting surface has an elliptical cross section, for example. It is a free-form surface having a surface and a horizontal cross section forming a paraboloid or a deformed paraboloid.

The light from the first light source 43 is reflected on the vehicle front side by the reflecting surface of the first reflector 40, and then a part of the reflected light is shielded by the shade, and the lens 20 is arranged on the vehicle front side. Is irradiated to the front side of the vehicle through the cylindrical lens 21.
Similarly, after the light from the second light source 53 is reflected to the vehicle front side by the reflecting surface of the second reflector 50, a part of the reflected light is shielded by the shade and arranged on the vehicle front side. The light is irradiated to the front side of the vehicle through the projection lens 22 of the lens 20.

(lens)
In the present embodiment, as the lens 20, a lens in which a cylindrical lens 21 and a projection lens 22 are integrated is used.
As shown in FIGS. 2 and 3, the cylindrical lens 21 is disposed on the vehicle outer side, and the projection lens 22 is disposed on the vehicle center side.
Also, as shown in FIG. 3, the projection lens 22 is arranged on the vehicle front side rather than the cylindrical lens 21, and the cylindrical lens 21 is about 10 ° to the axis in the vehicle width direction (horizontal direction). It arrange | positions so that it may incline to the back side.
For this reason, the light emitted from the cylindrical lens 21 toward the front side of the vehicle is irradiated toward the slightly outside front side of the vehicle.

  In the present embodiment, a lens in which the cylindrical lens 21 and the projection lens 22 are integrally formed is used, but it is not necessary to be limited to an integrally structured lens. A configuration in which a lens composed only of a cylindrical lens is used at the cylindrical lens 21 and a lens composed only of a projection lens is used at the projection lens 22, that is, two separate lenses are used. Also good.

  Since the cylindrical lens 21 has a lens effect in the vertical direction, the cylindrical lens 21 collects light from the first reflector 40, while there is not much lens effect in the vehicle width direction (left-right direction). Light having a spread corresponding to light from the vehicle is irradiated to the front side of the vehicle, and a diffusion type light distribution pattern that is long in the vehicle width direction, for example, a diffusion light distribution pattern of a low beam light distribution pattern is formed.

Here, the light that is rapidly condensed becomes the light that also starts to spread, and then spreads rapidly.
When the reflecting surface of the first reflector 40 is formed so as to be rapidly condensed, a focal point is formed at a position close to the reflecting surface, and the light is condensed at the position of the focal point. Therefore, the light has a spread suitable for being incident on the cylindrical lens 21 at a position not far from the focal point.
For this reason, the 1st reflector 40 can be arrange | positioned in the position close | similar to the cylindrical lens 21. FIG.

The cylindrical lens 21 has a light aspherical convex surface. On the other hand, the light incident surface of the cylindrical lens 21 may be flat or may be gently recessed toward the exit surface, or conversely, may have a gently convex shape toward the first light source 43 side.
Further, the overall shape of the cylindrical lens 21 may be a straight line in the left-right direction (vehicle width direction) or a shape that gently curves.

  On the other hand, the projection lens 22 is an aspherical convex lens. The light exit surface of the projection lens 22 has a convex aspherical surface with a large curvature (small curvature radius), while the light entrance surface has a shape such as a convex aspherical surface or a flat surface with a small curvature (large curvature radius). Have.

  When the reflecting surface of the second reflector 50 is formed so as to be gradually condensed, a focal point is formed at a position away from the reflecting surface, and light that spreads away from the focal point also becomes light that gradually spreads.

When the light that spreads gently becomes suitable for entering the projection lens 22, it is easy to control the light distribution to the emitted light close to the parallel light by making it enter the projection lens 22, and a good condensing type light distribution. An optical pattern, for example, a condensing light distribution pattern of a low beam light distribution pattern can be formed.
For this reason, compared with the distance from the 1st reflector 40 to the cylindrical lens 21, the distance from the 2nd reflector 50 to the projection lens 22 becomes long (refer FIG. 3).

(heatsink)
The heat sink 30 is made of a metal member or a resin member having a high thermal conductivity, and in the present embodiment, the heat sink 30 made of aluminum die cast is used.
4 is a cross-sectional view taken along line AA in FIG. In addition, although there exist a heat radiating fin etc. behind a vehicle from a reflector, in order to make a figure legible, these are abbreviate | omitting illustration.

As shown in FIG. 4, the base portion 31 of the heat sink 30 is provided with a first mounting surface 33 a for mounting the first light source 43 and a second mounting surface 33 b for mounting the second light source 53.
The first light source 43 is mounted on the first mounting portion 34a of the first mounting surface 33a, and the second light source 53 is mounted on the second mounting portion 34b of the second mounting surface 33b.
As can be seen from FIG. 4, the second mounting surface 33b is positioned on the vehicle lower side than the first mounting surface 33a.

Here, paying attention to the first reflector 40 and the second reflector 50, the first reflector 40 is fixed on the first vehicle center side connected to the reflector 40a on the second reflector 50 side of the reflector 40a, that is, on the vehicle center side. A portion 40b is formed, and a first vehicle outer side fixing portion 40c connected to the reflection portion 40a is formed at a position on the opposite side across the reflection portion 40a.
The first vehicle center side fixing portion 40b and the first vehicle outer side fixing portion 40c are formed with through holes for passing screws.

Similarly, the second reflector 50 is also formed with a second vehicle outer fixed portion 50b connected to the reflecting portion 50a on the first reflector 40 side of the reflecting portion 50a, that is, on the outer side of the vehicle, and is opposite to the reflecting portion 50a. A second vehicle center side fixing portion 50c connected to the reflecting portion 50a is formed at a position.
Through holes for passing screws are also formed in the second vehicle center side fixing portion 50c and the second vehicle outer side fixing portion 50b.

The base portion 31 of the heat sink 30 has a first vehicle center side fixing portion 40b of the first reflector 40 and a second vehicle outer side of the second reflector 50 at a position near the first mounting surface 33a of the second mounting surface 33b. A common attachment portion 35a for securing the fixing portion 50b with a screw is formed.
The common attachment portion 35a is formed with a female screw for screwing the screw.

The base portion 31 of the heat sink 30 has a vehicle center side mounting portion 35b for fixing the second vehicle center side fixing portion 50c of the second reflector 50 with a screw at a position on the vehicle center side of the second mounting surface 33b. A vehicle outer mounting portion 35c for fixing the first vehicle outer fixing portion 40c of the first reflector 40 with a screw is formed at a position outside the vehicle on the first mounting surface 33a.
The vehicle center side mounting portion 35b and the vehicle outer side mounting portion 35c are also formed with female screws for screwing screws.

  Hereinafter, the first reflector 40 and the second reflector 50 will be described in more detail, including the attachment state of the first reflector 40 and the second reflector 50 to the heat sink 30.

FIG. 5 is a front view of the heat sink 30 as viewed from the front side of the vehicle, and shows only the heat sink 30 with parts such as the lens 20 and the lens holder 24 removed.
As shown in FIG. 5, an attachment portion 37 for attaching the lens holder 24 and the like is provided on the vehicle forward side of the heat sink 30.
In this state, since the common attachment portion 35a described above is hidden behind the attachment portion 37 and cannot be seen, FIG. 6 shows a diagram in which this portion is omitted.

  As can be seen from FIG. 6, the upper surface of the common mounting portion 35a and the upper surface of the vehicle central side mounting portion 35b are located above the vehicle from the second mounting surface 33b so that both are located at substantially the same height as the first mounting surface 33a. It is formed so as to protrude to the side.

On the other hand, the upper surface of the vehicle outer mounting portion 35c is formed so as to slightly protrude upward from the first mounting surface 33a.
As can be seen from FIG. 4, the upper surface of the vehicle outer attachment portion 35c is positioned on the vehicle upper side by an amount corresponding to the thickness of the second vehicle outer fixing portion 50b of the second reflector 50. It is formed so as to protrude from the surface 33a to the vehicle upper side.

In addition, the thickness of the 1st vehicle center side fixing | fixed part 40b of the 1st reflector 40 and the thickness of the 1st vehicle outer side fixing | fixed part 40c are substantially the same thickness.
Moreover, the thickness of the 2nd vehicle outer side fixing | fixed part 50b of the 2nd reflector 50 and the thickness of the 2nd vehicle center side fixing | fixed part 50c are substantially the same thickness.

  Here, as described above, the upper surface of the vehicle outer mounting portion 35c is positioned above the vehicle by an amount corresponding to the thickness of the second vehicle outer fixing portion 50b of the second reflector 50 relative to the upper surface of the common mounting portion 35a. 4, as shown in FIG. 4, the upper surface of the vehicle outer mounting portion 35 c and the upper surface of the second vehicle outer fixing portion 50 b when the second vehicle outer fixing portion 50 b is disposed on the common mounting portion 35 a, It becomes substantially the same position in the vertical position of the vehicle.

Therefore, the first vehicle center side fixing portion 40b and the first vehicle outer side fixing portion 40c of the first reflector 40 to be disposed on the upper surface of the second vehicle outer side fixing portion 50b are substantially the same in height in the vehicle vertical direction. It will be fixed at the height position.
For this reason, even if the first vehicle center side fixing portion 40b and the first vehicle outer side fixing portion 40c of the first reflector 40 are formed symmetrically, when the first reflector 40 is attached to the base portion 31 of the heat sink 30, the first reflector 40 is provided. Does not tilt in the vertical direction of the vehicle.

  On the other hand, when the first reflector 40 is formed symmetrically in this way, it can be used as it is without changing the shape even in the lamp unit on the side opposite to the present embodiment, that is, on the left side of the vehicle.

Further, since the upper surface of the common mounting portion 35a and the upper surface of the vehicle center side mounting portion 35b are both formed to be substantially the same height position as the first mounting surface 33a, the upper surface of the common mounting portion 35a is also used. And the upper surface of the vehicle center side attachment portion 35b is substantially at the same height position in the vehicle vertical direction.
Accordingly, as in the case of the first reflector 40, the second vehicle center side fixing portion 50c and the second vehicle outer side fixing portion 50b of the second reflector 50 are fixed at substantially the same height in the vehicle vertical direction. Will be.

Therefore, even if the second vehicle center side fixing portion 50c and the second vehicle outer side fixing portion 50b of the second reflector 50 are formed symmetrically, the second reflector 50 is attached to the base portion 31 of the heat sink 30. Does not tilt in the vertical direction of the vehicle.
And since the 2nd reflector 50 is also formed symmetrically, it is possible to use as it is, without changing a shape also in the lamp unit on the opposite side to this embodiment, ie, the vehicle left side.

  As shown in FIG. 4, in the second reflector 50, the second reflecting portion 50 a and the second reflecting portion 50 a are arranged so that the reflecting portion 50 a is positioned at an appropriate height with respect to the second mounting surface 33 b of the heat sink 30. The shape of the connecting portions 55b and 55c connecting the vehicle center side fixing portion 50c and the second vehicle outer side fixing portion 50b is such that the shape bends upward in the vehicle after extending in the horizontal direction from the lower portion of the reflecting portion 50a. .

  As shown in FIG. 6, the heat sink 30 is provided with a plurality of radiating fins 38 extending downward on the vehicle lower side of the base portion 31 so as to be aligned in the vehicle width direction (left-right direction). A vertical wall 39a (see FIGS. 6 and 3) is provided at the rear end of the base portion on the vehicle upper side, and a plurality of radiating fins 39b extending from the vertical wall 39a to the vehicle front side are provided in the vehicle width direction (left and right). (The lower part of the heat radiating fins 39b is connected to the upper surface of the base part 31).

(Operational effect of this embodiment)
As described above, the first reflector 40 and the second reflector 50 are disposed on the base portion 31 of the heat sink 30 so as to be located at substantially the same position in the vehicle longitudinal direction.
As a result, the width of the heat sink 30 in the vehicle front-rear direction can be reduced as compared with the case where the heat sink 30 is displaced in the vehicle front-rear direction.

Further, the cylindrical lens 21 is disposed outside the vehicle, the projection lens 22 is disposed closer to the center of the vehicle than the cylindrical lens 21, and the distance from the first reflector 40 to the cylindrical lens 21 is the distance from the second reflector 50 to the projection lens 22. Shorter than the distance to.
That is, since the first reflector 40 and the second reflector 50 are substantially in the same position in the vehicle front-rear direction, the relationship between the distances is that the projection lens 22 is positioned closer to the front side of the vehicle than the cylindrical lens. Is equivalent.

  Here, many vehicular lamps have a shape (hereinafter also referred to as a slant shape) that is inclined from the front side of the vehicle toward the rear side from the center side of the vehicle, and includes a housing of the vehicular lamp and an outer lens. In many cases, the lamp chamber has a lamp chamber space from the vehicle center side to the vehicle front side rather than the vehicle outer side.

  As described above, the projection lens 22 that is positioned on the front side of the vehicle with respect to the cylindrical lens 21 is arranged on the vehicle center side, so that the lamp room space on the vehicle center side can be used without waste. A lens 22 can be arranged.

For example, when the projection lens 22 is located outside the vehicle, the position of the projection lens 22 is disposed on the vehicle rear side compared to the position on the vehicle center side due to the slant shape.
Then, the second reflector 50 and the like corresponding to the projection lens 22 are also arranged on the vehicle rear side as much as the projection lens 22 is arranged on the vehicle rear side. Since the lens 22 is arranged on the center side of the vehicle, such a situation does not occur and the vehicle lamp can be easily downsized.

  Further, in this embodiment, the first vehicle center side fixing portion 40b of the first reflector 40 and the second vehicle outer side fixing portion 50b of the second reflector 50 are fixed to the base portion 31 of the heat sink 30 so as to be fastened together. I have to.

  As described above, in order to reduce the width of the heat sink 30 in the vehicle front-rear direction, the first reflector 40 and the second reflector 50 are located at substantially the same position in the vehicle front-rear direction, and usually the reflector is fixed individually. Although an attachment part is provided and attached, if it does in this way, the space of the vehicle width direction (left-right direction) will be needed.

However, if the first vehicle center side fixing portion 40b of the first reflector 40 and the second vehicle outer side fixing portion 50b of the second reflector 50 are fastened together as in the present embodiment, the first reflector 40 and the second reflector 40 Since the reflectors 50 can be disposed close to each other, the space required in the vehicle width direction (left-right direction) can be minimized.
Therefore, the size can be reduced also in the vehicle width direction (left-right direction).

  In addition, in the present embodiment, the first reflector is devised by devising the position of the upper surface of each mounting portion (common mounting portion 35a, vehicle center side mounting portion 35b, and vehicle outer side mounting portion 35c) of the heat sink 30 in the vehicle vertical direction. The first reflector 40 and the second reflector 50 can be attached to the base portion 31 of the heat sink 30 without tilting in the vehicle vertical direction while making the shapes of the 40 and the second reflector 50 symmetrical.

Thus, the shape of the first reflector 40 and the second reflector 50 is made symmetrical, so that it can be used for both the left and right vehicle lamps.
That is, common parts are realized, and the manufacturing cost of the first reflector 40 and the second reflector 50 can be reduced.

In addition, if it is a reflector which formed the several reflector part by integral structure like the prior art, in order to change the arrangement | positioning relationship of each reflector part, it is necessary to change the shape of reflector itself.
However, by using a separate reflector as in the present embodiment, for example, in a different type of vehicle lamp, it is possible to simply change the arrangement state of the reflector without changing the shape of the reflector itself. In such a case, this reflector can be used as it is, so that the versatility of the reflector can be improved.

  In addition, in the present embodiment, the first reflector 40 and the cylindrical lens 21 are arranged so as to be slightly inclined with respect to the axis in the vehicle width direction, so that the light from the first light source is directed slightly forward to the outside of the vehicle. As a result, it is possible to improve the visibility on the outside of the vehicle.

  As described above, the present invention has been described based on specific embodiments. However, the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within a range in which the object of the present invention can be achieved. It is included in the present invention.
