Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp for illumination such as a headlamp and a fog lamp, and more particularly to a reflector having two focal points, such as a spheroid and a compound ellipsoid, which is called a projector type. The present invention relates to a lamp mainly comprising a projection lens for projecting an image of a light source placed at a first focal point, which forms an image at a second focal point of the reflector, and a shade for adjusting light distribution characteristics.

[0002]

2. Description of the Related Art FIG. 11 shows a configuration of a conventional projector-type lamp 90 by way of an example of a headlamp. This projector-type lamp 90 has a first focal point and a second focal point, for example, a compound elliptical surface. Reflector 91, a light source 92 placed at the first focal point, a shade 93 provided near the second focal point, and an aspheric convex lens having a focal point near the shade 93. It comprises a lens 94 and a housing (not shown) for holding these in a predetermined position.

[0003] With this configuration, all of the light from the light source 92 reflected by the reflecting mirror 91 becomes convergent light that converges to the second focal point. At this time, since the shade 93 is provided in the vicinity of the second focal point, the convergent light has a shape in which the lower half portion is shielded, and this shape is inverted by the projection lens 94 and irradiated. The light distribution characteristic for a low-pass beam which does not include upward light is projected in an enlarged manner in the direction.

[0004]

However, in the above-mentioned conventional projector-type lamp 90, the projection lens 94 serves as a light emitting surface when it is turned on, so that the light emitting area is, for example, a parabolic reflecting mirror and a lens cut. Lamps using other types of lamps, such as those using a lens, and have a problem that visibility from oncoming vehicles or pedestrians is reduced.

The projection lens 94 has a circular shape when viewed from the front, and only the projection lens 94 is visible when mounted on a vehicle.
Each lamp has the same impression. For example, it is practically impossible to produce a difference in design depending on the type of vehicle or the like, and there is a problem that the degree of freedom in design is lacking.

Further, as described above, since the projection lens 94 is smaller than other types of lamps, the heat of the light source 92 is also concentrated on the projection lens 94 and the temperature rises remarkably. Therefore, it is necessary to employ a glass member, and there is a problem that it is difficult to reduce the weight while increasing the cost, and it is an issue to solve these points.

As for the degree of freedom in the design aspect, a method is proposed in which the projection lens 94 is cut off at the upper and lower ends as shown in FIG. However, in this case, the light-emitting area at the time of lighting becomes smaller, the visibility is reduced, the light amount is lost, and the arrangement of the shade 93 becomes more difficult. The formation of optical characteristics is also restricted, and does not completely solve the problem.

[0008]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, a light source, a projection lens, a reflecting mirror, a shade provided as necessary, and In a projector-type lamp comprising a housing, a cylindrical lens portion having a curved section in a vertical cross section in a mounted state is formed in a central portion, and the left and right end portions of the cylindrical lens portion each have a center. An aspherical lens portion having a shape that is divided into two by a cross section passing through and is in contact with the divided surface, and the reflecting mirror has an upper reflecting surface, a lower reflecting surface, a left reflecting surface, and a right reflecting surface that are positioned substantially in the up, down, left, and right directions in the mounted state. Divided into four reflection surfaces,
An object of the present invention is to solve the problem by providing a projector-type lamp characterized in that each is configured as a curved reflecting surface based on an ellipse and is combined.

[0009]

Next, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 shows a first embodiment of a projector-type lamp according to the present invention. The projector-type lamp 1 according to the first embodiment is a light source such as a halogen bulb or a metal halide discharge lamp. 2, a projection lens 3, a reflecting mirror 4,
For example, the shade 5 is provided with a shade 5 provided as necessary, for example, when forming a low-beam light distribution characteristic, and a housing for holding these, although not shown, as in the conventional example. .

Here, in the present invention, the projection lens 3 comprises a cylindrical lens portion 31 and aspherical lens portions 32 and 33. First, the cylindrical lens portion 31 is located at the center of the projection lens 3. When the projector-type lamp 1 is mounted on a vehicle or the like, a vertical section shows a curve forming a lens, and a horizontal section shows a linear lens (cylinder lens or cylindrical lens). .

Therefore, the cylindrical lens portion 31
Shows the same shape in the vertical cross section at any position. The shape of only the cylindrical lens portion 31 is rectangular when viewed from the front, and the right and left ends have the same shape as the vertical cross section. Has emerged.

The aspheric lens portions 32 and 33 are provided at the left and right ends of the cylindrical lens portion 31, respectively. At this time, the projection lens, which is the aspheric lens used in the conventional example, is centered. Are divided into two at the cross section passing through, and the divided surface is in contact with the above-mentioned left and right ends.

At this time, it is preferable that no step is formed at the portion where the cylindrical lens portion 31 and the aspherical lens portions 32 and 33 are joined. It is only necessary to design an aspheric lens suitable for forming, and determine the shape of the vertical cross section of the cylindrical lens portion 31 so as to have the same curvature as that of the aspheric lens. The lens units 32 and 33 have the same focal length.

By forming the projection lens 3 as described above, the shape of the projection lens 3 when viewed from the front is a substantially oval shape that is longer in the horizontal direction than in the vertical direction. here,
As a result of trial manufacture and study by the inventor to achieve the present invention, the aspect ratio of the projection lens 3 (aspect ratio) is 1: 1.2 to from the viewpoint of compatibility with the reflecting mirror 4 described later.
It was confirmed that the ratio was in the range of 1: 5.

In addition, the results of the above-mentioned trial production and examination confirmed that when the projection lens 3 was configured as described above, it was more effective to configure the reflecting mirror 4 corresponding to the configuration. Hereinafter, a configuration of the reflecting mirror 4 suitable for being combined with the projection lens 3 will be described.

According to the present invention, the reflecting mirror 4 includes an upper reflecting surface 41, a lower reflecting surface 42, a right reflecting surface 43, and a left reflecting surface 44 radially about the optical axis Z of the projector lamp 1.
The above-described division is performed within a range of 10 to 45 degrees vertically with respect to a horizontal line H passing through the optical axis Z when the projector-type lamp 1 is mounted on a vehicle or the like. I have.

The upper reflecting surface 41 and the lower reflecting surface 42
Means that an ellipse having a first focal point at the position of the light source 2 and a second focal point near the focal point of the cylindrical lens portion 31 appears on the vertical cross-sectional side, and the ellipse on the horizontal cross-sectional side appropriately within the range of the cylindrical lens portion 31 Is formed so that a free curve having a spread angle appears.

The right reflecting surface 43 is formed as an elliptical surface having a first focal point at the position of the light source 2 and a second focal point at the focal position of the aspheric lens unit 32 in both the vertical and horizontal sections. Similarly, the left reflecting surface 44 is formed as an elliptical surface having a first focal point at the position of the light source 2 and a second focal point at the focal position of the aspheric lens unit 33.

By forming the reflecting mirror 4 as described above,
The reflected light of the light source 2 from the upper reflection surface 41 and the lower reflection surface 42 converges on the cylindrical lens portion 31 in the up-down direction and is appropriately diffused in the left-right direction. Light from the left reflecting surface 44 is converged and incident on the aspherical lens unit 32, and light from the left reflecting surface 44 is
3 and is incident.

When the projector type lamp 1 is required to have a light distribution characteristic for passing beams, the reflecting mirror 4 is used.
Is provided with a shade 5 for shielding a portion of the reflected light from the light which becomes upward light after passing through the projection lens 3. The shade 5 has, for example, a projector-type lamp 1 for left-hand traffic. In such a case, in order to improve the visibility of a sign or the like on the left road side, a cutout for irradiating an appropriate upward light on the left side and providing an asymmetrical light distribution on the left and right sides is usually provided.

Here, in the present invention, the cutout provided in the shade 5 is provided in two places, a right cutout 51 and a left cutout 52, as opposed to one in the conventional example. The position of the projection lens 3
The position substantially corresponds to the boundary between the cylindrical lens portion 31 and the aspherical lens portion 32 and the boundary between the cylindrical lens portion 31 and the aspherical lens portion 33.

By doing so, the aspheric lens portion 3
2 and the aspheric lens portion 33 have substantially the same cross-sectional shape. For example, at a position 10 m ahead of the projector-type lamp 1, the distance between the aspheric lens portion 32 and the aspheric lens portion 33 is Since the light beams are substantially negligible, the light beams from the two lens portions 32 and 33 are overlapped with each other to obtain a desired asymmetric light distribution characteristic such as for left-hand traffic.

FIG. 2 schematically shows the overall light distribution characteristic H1 of the projector type lamp 1 when the shade 5 is provided and the light distribution for a low beam is used. It is formed by combining light distribution characteristics H41 formed by light from 41 and 42 and light distribution characteristics H43 formed by light from the left and right reflection surfaces 43 and 44.

At this time, the reflected lights from the upper and lower reflecting surfaces 41 and 42 converge in the vertical direction as described above, and have an appropriate radiation angle in the horizontal direction. Since the light is made incident, the radiation angle in the horizontal direction does not change even after passing through the cylindrical lens unit 31, only the convergence in the vertical direction is performed, and the shade 5 blocks the upward light. Therefore, as shown in the figure, the light distribution characteristic H41 of a relatively low illuminance, which is wide in the horizontal direction, narrow in the vertical direction, and does not include upward light.
Is obtained.

On the other hand, the reflected lights from the left and right reflecting surfaces 43, 44 are both converged by the aspherical lens portions 32, 33 to form a spot and have a relatively high illuminance near the center of the overall light distribution characteristic H1. At this time, an asymmetric shape is given by the left and right cutouts 51 and 52 provided in the shade 5, whereby the overall light distribution characteristic H1 can be obtained as an appropriate shape as a low-beam light distribution. Becomes

That is, according to the present invention, desired light distribution characteristics can be obtained even when the projection lens 3 has a substantially oval shape. For example, the length of the cylindrical lens portion 31 in the horizontal direction can be obtained. , The lamp shape design can be easily changed. Further, since the projection lens 3 has the above-described shape, the area for transmitting the light from the reflecting mirror 4 is increased, and the temperature rise is reduced. For example, the projection lens 3 can be made of resin.

FIG. 3 shows a second embodiment of the present invention. Also in this second embodiment, the projection lens 3 includes a cylindrical lens portion 31, an aspherical lens portion 32,
3 is provided, and the reflecting mirror 4 is provided with upper and lower reflecting surfaces 41 and 42 and left and right reflecting surfaces 43 and 44, in the same configuration as in the first embodiment. 5 is provided in the same manner.

Here, in the second embodiment,
A right auxiliary reflection surface 45 and a left auxiliary reflection surface 46 are provided outside each of the left and right reflection surfaces 43 and 44. The left and right auxiliary reflection surfaces 45 and 46 are provided on the left and right reflection surfaces 43 and 44 in the first embodiment. It may be provided by dividing a part and omitting it.

The left and right auxiliary reflection surfaces 45, 46

It is formed so that a free curve having an appropriate divergence angle appears within the range of the cylindrical lens unit 31, and the reflected light is made to enter the cylindrical lens unit 31.

FIG. 4 shows the overall light distribution characteristic H10 of the second embodiment having the above-described configuration, and the overall light distribution characteristic H10 is the same as the vertical light reflection characteristic H1 of the first embodiment. In addition to the light distribution characteristics H41 by the surfaces 41 and 42 and the light distribution characteristics H43 by the left and right reflection surfaces 43 and 44, the light distribution characteristics H
The light distribution characteristics H45 of the right auxiliary reflection surface 45 and the light distribution characteristics H46 of the left auxiliary reflection surface 46 are added to both ends outside the outer surface 41, so that a light distribution shape wider in the horizontal direction can be obtained.

Similarly, the boundary between 44 and the left auxiliary reflection surface 48 is set according to the cylindrical lens unit 31 and the aspheric lens unit 33.

The left and right reflecting surfaces 43 and 44 are the first,
Similarly to the second embodiment, light having a relatively narrow irradiation angle is formed as an elliptical surface having a second focal point at a position substantially at the focal point of the aspherical lens parts 32 and 33, and via the aspherical lens parts 32 and 33. In the third embodiment, the left and right auxiliary reflection surfaces 47 and 48 are also configured to cause the reflected light to enter the aspheric lens portions 32 and 33, and the left and right auxiliary reflection surfaces 45 and This is different from the second embodiment in which the reflected light from 46 is incident on the cylindrical lens unit 31.

Accordingly, the left and right auxiliary reflection surfaces 47 and 48 are based on an elliptical surface having a second focal point near the apex of the aspherical lens portions 32 and 33 so that light enters the aspherical lens portions 32 and 33. It is formed as a reflection surface shape. still,
By adjusting the position of the second focal point between the vertices of the aspheric lens parts 32 and 33 and the focal point, the emission angle of the emitted light can be freely adjusted.

FIG. 6 shows the total light distribution characteristic H11 of the third embodiment having the above-described configuration. The total light distribution characteristic H11 is the total light distribution characteristic H1 of the first and second embodiments.
In addition to the light distribution characteristic H41 by the upper and lower reflection surfaces 41 and 42 and the light distribution characteristic H43 by the left and right reflection surfaces 43 and 44,
Left and right auxiliary reflection surfaces 47 and 48 are provided at the center in the light distribution characteristic H41.
The light distribution characteristics H47 are superimposed on each other, and the visibility of the vehicle in the far front direction is further improved.

Has a cylindrical lens portion 31 and an aspherical lens portion 3
2 and 33 are provided, and the reflecting mirror 4 is provided with upper and lower reflecting surfaces 41 and 42 for allowing light to enter the cylindrical lens portion 31. This is the same configuration as that of the first embodiment. The same applies to the point that the shade 5 is provided according to.

In the horizontal direction, left and right reflecting surfaces 43 and 44 are provided.
The left and right auxiliary reflection surfaces 47 and 48 are provided on the outer sides of the left and right reflection surfaces 43 and 44, respectively.
The third embodiment is similar to the third embodiment in that light from the left and right auxiliary reflection surfaces 47 and 48 is incident on the aspheric lens portions 32 and 33.

Considering the operation of the left and right auxiliary reflection surfaces 47 and 48 in the third embodiment, the second focal points of the left and right auxiliary reflection surfaces 47 and 48 are the focal points of the aspheric lens portions 32 and 33. , In other words, is set forward of the shade 5 in the irradiation direction, so that when passing through the position of the shade 5, convergence is not yet sufficiently performed, and the light beam has a considerable area.

Accordingly, in the third embodiment, the light reflected by the lower half of the light reflected from the left and right auxiliary reflection surfaces 47 and 48 is almost blocked by the shade 5 and becomes ineffective. The fourth embodiment has been made in consideration of this point,
The right auxiliary reflecting surface 47 is further divided into an upper right auxiliary reflecting surface 47U and a lower right auxiliary reflecting surface 47D by a horizontal line H passing through the optical axis Z, and the left auxiliary reflecting surface 48 is similarly divided into the upper left auxiliary reflecting surface 4D.

The vertical cross-section side is formed on the basis of an elliptical surface that substantially positions the second focal point on an extension of the focal point of the projection lens 3 extending outward.

With this configuration, the reflected light from the left and right lower auxiliary reflecting surfaces 47D and 48D is reflected by the shade 5
When the light passes through the position where is provided, the convergence is completely performed in the vertical cross-sectional direction and the light becomes linear, so that almost all the light amount is not blocked by the shade 5 and the aspherical lens portions 32 and 33 of the projection lens 3 are formed. , That is, it can be used as irradiation light.

FIG. 8 shows the total light distribution characteristic H12 of the fourth embodiment having the above-described configuration, and the total light distribution characteristic H12 is the total light distribution characteristic H12 of the first, second, and third embodiments. In addition to the light distribution characteristic H41 by the upper and lower reflection surfaces 41 and 42 and the light distribution characteristic H43 by the left and right reflection surfaces 43 and 44 similar to the light distribution characteristic H1, the left and right upper auxiliary reflection surfaces 47U are provided at the center in the light distribution characteristic H41.

The shade 5 appears to be enlarged.

Therefore, in the fifth embodiment, the surface 5 of the shade 5 on the side of the projection lens 3 is subjected to a reflection treatment 5a by, for example, vacuum evaporation of aluminum, or a coloring treatment 5b by painting the same color as the body color. In this manner, when the projector-type lamp 1 is not turned on, reflection processing 5a (or coloring processing 5b) is performed by external light.
Will be visible to the viewer.

At this time, in the case of the reflection processing 5a, almost the entire surface of the projection lens 3 shines with metallic luster, and the presence of the projector type lamp 1 is further emphasized. On the other hand, almost the entire surface of the projection lens 3 becomes a vehicle body color, and conversely, the presence of the projector type lamp 1 is not made conscious, and the degree of freedom in designing which one to select is improved.
