JP 2017-211432 A

By the way, when a light pattern for drawing an image has high luminosity in the center and low luminosity in the periphery, the image drawn in the pattern of light with low luminosity in the periphery tends to be blurred.

For this reason, for example, when the center of the light pattern is aligned with the position where the vertical reference line and the horizontal reference line intersect on the screen, the light pattern projected on the road surface near the vehicle will be a low-luminance area in the periphery. Therefore, when an image such as a warning display is drawn there, the warning display may become blurred.

In recent years, there has been an increasing demand for downsizing of vehicle lamps. Therefore, it is desired to reduce the size of the vehicle lamp when incorporating a configuration capable of projecting an image.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the form (henceforth "embodiment" is called) for implementing this invention is demonstrated in detail.

As shown in FIG. 1, the vehicle lamp according to the embodiment of the present invention is a vehicle headlamp (101L, 101R) provided on each of the left and right sides in front of a vehicle 102. Hereinafter, the vehicle lamp will be simply referred to as a vehicle lamp. and described.

The vehicular lamp of this embodiment includes a housing (not shown) that opens toward the front of the vehicle and an outer lens (not shown) that is attached to the housing so as to cover the opening, and is formed by the housing and the outer lens. A lamp unit 1 (see FIG. 2) and the like are arranged in the lamp chamber.

FIG. 2 is a perspective view of a lighting unit 1 according to an embodiment of the invention, and FIG. 3 is a cross-sectional view showing a main part of the lighting unit 1 according to an embodiment of the invention.
FIG. 3 is a cross-sectional view showing a main part of the lens part 50 of the lamp unit 1 when cut in the front-rear direction at the center position in the left-right direction. Illustration of other parts is omitted.

As shown in FIG. 2, the lamp unit 1 includes a heat sink 10, a light source device 20, a two-dimensional light control device 30, a relay optical section 40, a lens section 50, and a light blocking section 60 (see FIG. 3). , is mainly provided.

The heat sink 10 is a base for assembling the light source device 20, the two-dimensional light control device 30, the relay optical section 40, and the lens section 50, and also serves to cool the light source device 20, so that heat dissipation is high. The heat sink 10 is made of good material, for example, aluminum die-cast in this embodiment.

The light source device 20 is a part that forms light controlled by the two-dimensional light control device 30. As will be described later, a light source 21 (see FIG. 3) and the light from the light source 21 are directed to the relay optical section 40. and a holding unit 23 for holding the irradiation lens unit 22 so as to position the irradiation lens unit 22 at a predetermined position with respect to the light source 21 .

The two-dimensional light control device 30 is arranged in a two-dimensional matrix and includes a light irradiation section 31 (see FIG. 3) having a plurality of micromirrors for controlling the reflection direction (irradiation direction) of light. device (DMD) and the like.

As shown in FIG. 3, the two-dimensional light control device 30 is arranged on the rear side facing the lens unit 50 so that the light irradiation unit 31 faces the lens unit 50 side.

In this embodiment, the lens optical axis Z1 (see FIG. 3) of the lens portion 50 is set slightly below the vertical center of the lens area, excluding the flange portion described later. center substantially coincides with the lens optical axis Z1 (see FIG. 3).

Therefore, the two-dimensional light control device 30 is arranged so that the center of the light irradiation section 31 is positioned below the center of the lens section 50 (the physical center of the lens area) when viewed in the vertical direction. there is

As shown in FIG. 2, the relay optical unit 40 is attached to a support unit 70 attached to the upper surface 10A of the heat sink 10, which is inclined to the upper side of the heat sink 10, and transmits the light from the light source device 20 to the two-dimensional light control device. It is a member that reflects toward 30 .
On the opposite side of the surface 10A of the heat sink 10, a plurality of radiation fins are arranged in the left-right direction and extend in the front-rear direction.

In this embodiment, the support portion 70 has a wall surface extending from the heat sink 10 side to almost above the lens portion 50, and a pair of left and right arm portions 71 for attaching the relay optical portion 40 extend forward from the wall surface. An opening 72 is formed in the wall surface to allow the light irradiation section 31 (see FIG. 3) of the two-dimensional light control device 30 to face the lens section 50 .

The two-dimensional light control device 30 is supported by a support structure 80 different from the support portion 70 fixed to the heat sink 10 so that the position of the light irradiation portion 31 (see FIG. 3) is aligned with the opening portion 72. It is attached to a heat sink (not shown) that cools the two-dimensional light control device 30 .

However, a heat sink (not shown) for cooling the two-dimensional light control device 30 to which the two-dimensional light control device 30 is attached is attached to the support portion 70, and the light irradiation portion 31 (see FIG. 3) is positioned in the opening portion 72. A two-dimensional light control device 30 may be positioned accordingly.

In the present embodiment, as shown in FIG. 3, the relay optical unit 40 is formed as an inwardly curved concave mirror, and directs the light from the light source device 20 toward the light irradiation unit 31 of the two-dimensional light control device 30 (direct It has a reflective surface 41 that reflects light so as to condense it.

However, the relay optical unit 40 does not need to be limited to such a form. It may be composed of an optical member that is reflective so as to focus the light toward it.

As shown in FIG. 3, the lens portion 50 is formed by combining two or more lenses (a front lens 51 and a rear lens 52) made of resin. not shown) are formed.

2, the lens portion 50 is held by a lens holder 90 attached to the support portion 70 by the flange portions (not shown) of the lenses, thereby , and projects the light from the two-dimensional light control device 30 to the front side.

In this embodiment, the lens unit 50 includes a front lens 51 arranged on the front side and a rear lens 52 arranged on the rear side of the front lens 51 .

The front lens 51 is a biconvex lens in which both the entrance surface 51A and the exit surface 51B protrude outward, and the rear lens 52 is curved in such a manner that the entrance surface 52A protrudes outward. Together, it forms a concave meniscus lens curved so that the exit surface 52B is concave inward.

The front lens 51 is made of resin with low refractive index and low dispersion (for example, acrylic resin), and the rear lens 52 is made of resin with high refractive index and high dispersion (for example, polycarbonate resin). etc.) is used, and the front lens 51 and the rear lens 52 have different Abbe numbers (in this example, the front lens 51 has a higher Abbe number than the rear lens 52), and further , the lens unit 50 cancels chromatic aberration by shifting the amount of chromatic aberration in the front-rear direction from the center side (lens optical axis Z1 side) toward the outside in the radial direction.

In the present embodiment, the lens portion 50 is made up of two lenses made of resin, but the lens portion 50 may be made up of three or more lenses made of resin.
However, if the lenses are made of resin, the selection range of materials is small when considering the combination of refractive index and dispersion. should be made of glass.

For example, when the lens unit 50 is composed of a front lens arranged on the front side, a rear lens arranged on the rear side, and a center lens arranged between the front lens and the rear lens, The front lens is a plano-convex lens with a flat entrance surface (rear surface) and a curved exit surface (front surface) that protrudes outward, while the rear lens has a rear surface that projects outward. A plano-convex lens with a flat exit surface (front surface) may be used, and the central lens may be a biconcave lens with both the entrance surface (rear surface) and the exit surface (front surface) curved inwardly.

In this case, the glass material forming the front lens, the rear lens, and the central lens is, for example, the refractive index for the sodium D line of the front lens, the rear lens, and the central lens is 1.6. , the Abbe number of the central lens is lower than that of the front lens and the rear lens.
For example, as an example, the material of the front lens and the rear lens may be crown glass, and the material of the central lens may be flint glass.

As will be described later, the light blocking unit 60 (see FIG. 3) is provided when the two-dimensional light control device 30 performs control to prevent at least part of the light from entering the lens unit 50, that is, at least the micromirrors. When some of the micromirrors are controlled not to reflect light toward the lens unit 50 , the light is reflected toward the light source device 20 . It is a member that blocks.

Next, a more detailed configuration will be described while describing a state in which the light source device 20 is caused to emit light.
As shown in FIG. 3, the light source device 20 includes a light source 21 having a substrate 21A and a semiconductor-type light emitting portion 21B provided on the substrate 21A.

In this embodiment, the light-emitting portion 21B is formed of an LED element, and a plurality of square LED elements are connected in the left-right direction (the paper surface direction of FIG. 3) without leaving a gap to form one horizontally long rectangular shape in the left-right direction. is a light emitting portion 21B.
Therefore, the light source 21 of the present embodiment is provided with one light-emitting portion 21B having a horizontally long rectangular shape in the left-right direction.

As mentioned above, the light source device 20 includes the irradiation lens section 22. As shown in FIG. and a second lens 22B located closer to the relay optical unit 40 than the first lens 22A. The holding portion 23 ( 2).

For example, since the first lens 22A is located on the light source 21 side, it is preferably made of a polycarbonate-based resin having excellent heat resistance. does not need to be considered so much, and may be formed from an acrylic resin or a polycarbonate resin.

However, the first lens 22A is not limited to being made of a polycarbonate resin because there are cases where acrylic resin can be used without problems depending on the output of the light source 21 or the like.
In addition, it is conceivable that the output of the light source 21 will be increased. From this point of view, it may be preferable to use polycarbonate resin for the second lens 22B. When both are made of polycarbonate resin, the thickness of the irradiation lens portion 22 in the direction along the irradiation optical axis Z2 of the light emitted from the light source 21 can be reduced.

Although not shown in FIG. 3, the first lens 22A and the second lens 22B have flanges around them, and the flanges are held by the holder 23 (see FIG. 2). ing.

In this embodiment, the light source 21 is arranged on the surface 10A (see FIG. 2) of the heat sink 10 (see FIG. 2), and the portion of the support portion 70 (see FIG. 2) positioned around the light source 21 is Although the holding portion 23 is attached, the holding portion 23 may be attached to the surface 10A (see FIG. 2) of the heat sink 10 (see FIG. 2).

Here, as shown in FIG. 3, both the first lens 22A and the second lens 22B have an incident surface (surface facing the light source 21 side) and an exit surface (surface facing the relay optical section 40 side). It is a biconvex lens curved to protrude outward.

For this reason, the rectangular light pattern P1 from the light emitting part 21B of the light source 21 is not collapsed, and the unevenness of the luminous intensity in the light pattern P1 is suppressed toward the reflecting surface 41 of the relay optical part 40. It is easier to design to irradiate light.

Since the light pattern P1 irradiated onto the reflecting surface 41 of the relay optical unit 40 can be formed into a rectangular shape with little unevenness of the luminous intensity in the light pattern P1, the light irradiation unit 31 has a horizontally long rectangular shape. The reflective surface 41 is designed so as to make the pattern P2 of the light reflected so as to converge the light toward the light irradiation unit 31 of the two-dimensional light control device 30 and to have a light pattern P2 with less unevenness of the luminous intensity. Cheap.

Therefore, since the light can be irradiated to the entire surface of the light irradiation unit 31 without unevenness in luminous intensity, the rectangular light distribution pattern projected forward through the lens unit 50 is also included in the light distribution pattern. luminous intensity bias can be suppressed.

FIG. 4 is a diagram for explaining a light distribution pattern on the screen formed by the lamp unit 1. FIG.
In FIG. 4, the HL-HR line indicates a horizontal reference line on the screen, and the VU-VL line indicates a vertical reference line on the screen.
Also, in FIG. 4, the state of the low-beam light distribution pattern LP formed by the light from the lighting unit that forms the low-beam light distribution pattern LP different from that of the lighting unit 1 is indicated by a dotted line.

As shown in FIG. 4, when the light reflection directions of all the micromirrors of the light irradiation unit 31 of the two-dimensional light control device 30 are controlled to enter the lens unit 50, the left and right beams are projected onto the screen via the lens unit 50. A horizontally long rectangular light distribution pattern AP is formed.

Specifically, the light distribution pattern AP corresponds to a high-beam additional light distribution pattern for forming a high-beam light distribution pattern by multiplexing the low-beam light distribution pattern LP above the horizontal reference line (refer to the HL-HR line). The light distribution pattern covers from the light distribution area APU to the light distribution area APL including the area where the warning display etc. are displayed on the road surface near the vehicle 102 below the horizontal reference line (see the HL-HR line). there is

As described above, since the light distribution pattern AP has less unevenness in luminous intensity, the micromirrors are individually controlled so that part of the light is not projected onto the screen side and a warning display is performed. Even when drawing etc., the warning display etc. will not be blurred.

On the other hand, as shown in FIG. 3, the relay optical unit 40 is arranged at a position between the two-dimensional light control device 30 and the lens unit 50 when viewed in the front-rear direction. It is arranged above the light (see light pattern P3) irradiated from the two-dimensional light control device 30 so as to enter the lens unit 50, and at least a part (approximately) of the reflecting surface 41 when viewed in the vertical direction. all) is above the light (see light pattern P3) irradiated from the two-dimensional light control device 30 to enter the lens unit 50, and at least a part (almost all) of the reflecting surface 41 is It is arranged so as to be positioned below the upper end of the lens portion 50 .

In this embodiment, if the upper end of the flange portion held by the lens holder 90 of each lens (the front lens 51 and the rear lens 52) of the lens portion 50 (not shown in FIG. 3) is defined as the upper end of the lens portion 50, , the relay optical section 40 is arranged so that almost all of the relay optical section 40 is located below the upper end of the lens section 50 .

Further, the light source device 20 is positioned between the two-dimensional light control device 30 and the lens unit 50 when viewed in the front-rear direction, and is positioned between the two-dimensional light control device 30 and the lens unit 50 when viewed in the vertical direction. It is arranged at a position that does not block the light (see light pattern P3) irradiated to enter the unit 50, and more specifically, the light source device 20 has two irradiation lens units 22 when viewed in the vertical direction. Below the light (see light pattern P3) irradiated from the dimensional light control device 30 to enter the lens section 50, and at least part of the irradiation lens section 22 is below the lower end of the lens section 50 It is arranged so as to be positioned on the upper side.

In the present embodiment, if the lower end of the flange portion held by the lens holder 90 of each lens (the front lens 51 and the rear lens 52) of the lens portion 50 (not shown in FIG. 3) is defined as the lower end of the lens portion 50, , the light source device 20 is below the light (see light pattern P3) irradiated from the two-dimensional light control device 30 so that the second lens 22B is incident on the lens unit 50 when viewed in the vertical direction. In addition, almost all of the second lens 22B is positioned above the lower end of the lens portion 50. As shown in FIG.

In this way, the light source device 20 and the relay optical unit 40 are controlled as much as possible while preventing the light emitted from the two-dimensional light control device 30 to enter the lens unit 50 (see light pattern P3). Since it is made to be close to the light (see light pattern P3) irradiated from the control device 30 so as to be incident on the lens unit 50, the size in the vertical direction is made compact, so that the size of the vehicle lamp can be easily reduced. ing.

Note that, for example, above the lighting unit 1, there are cases where a lighting unit forming the low-beam light distribution pattern LP and another lighting unit for forming the high-beam light distribution pattern are arranged. By arranging the light source device 20 on the lower side, the light source device 20 can be made less susceptible to heat.

In addition, with such a compact arrangement, the micromirror is driven when the two-dimensional light control device 30 controls not to allow at least part of the light to enter the lens unit 50 in order to draw a warning display or the like. Then, when the light is reflected obliquely downward, the light is reflected toward the light source device 20 .

However, as mentioned earlier, in the present embodiment, between the two-dimensional light control device 30 and the light source device 20 (more specifically, between the two-dimensional light control device 30 and the second lens 22B of the irradiation lens unit 22) ) to block the light emitted from the two-dimensional light control device 30 from entering the light source device 20 (more specifically, the second lens 22B).

Therefore, when controlling at least part of the light not to enter the lens unit 50, the two-dimensional light control device 30 can irradiate the light blocking unit 60 with the light that is not allowed to enter the lens unit 50. The device 20 (the second lens 22B) prevents the light from being diffusely reflected and projected forward, thereby preventing glare.

For example, the light blocking section 60 is inclined rearward and upward so that the light blocking surface 61 faces the light irradiation section 31 of the two-dimensional light control device 30 so as to easily receive the light from the two-dimensional light control device 30 . In order to increase the light blocking power, the light blocking surface 61 is preferably made uneven to increase light scattering attenuation, and is preferably painted or vapor-deposited in a color that easily absorbs light.

In the present embodiment, the light blocking surface 61 is made uneven by providing a plurality of fin-shaped protrusions extending in the left-right direction in the front-rear direction. It may be one in which fine unevenness is formed by subjecting the surface to surface processing or the like.

On the other hand, when the two-dimensional light control device 30 controls not to allow at least part of the light to enter the lens unit 50 in order to draw a warning display or the like, the micromirror is driven to reflect the light obliquely forward and upward. It is also possible to let

However, in this case, similarly, even if a light blocking portion is provided, if light that cannot be blocked is generated due to vibration of the vehicle 102 or the like, the leaked light is projected above the horizontal reference line of the screen. Since the probability of glare is higher than when the light is reflected obliquely forward and downward, the two-dimensional light control device 30 controls at least part of the light not to enter the lens unit 50 as in the present embodiment. When doing so, it is preferable to drive the micromirror so that the light escapes obliquely forward and downward.

Further, in the present embodiment, the light source device 20 is arranged so that the irradiation optical axis Z2 of the light emitted from the light source 21 is directed obliquely forward and upward. It is arranged so that the point where it intersects with Z2 is offset to the front side with respect to the vertical axis V passing through the light emission center O of the light emitting portion 21B.

Therefore, the relay optical unit 40 is arranged so that the reflecting surface 41 reflects the light from the light source device 20 toward the light irradiation unit 31 of the two-dimensional light control device 30 at a gentle angle toward the rear obliquely downward direction. Therefore, it is possible to prevent the shape of the reflecting surface 41 for performing control of condensing light toward the light irradiating section 31 from being unreasonable, and the entire light irradiating section 31 is irradiated with light with a substantially uniform luminous intensity. be able to.

Therefore, it is possible to make the luminous intensity in the light distribution pattern AP on the screen even more uniform.

As described above, according to the present embodiment, since both the first lens 22A and the second lens 22B are biconvex lenses, a rectangular lens with uniform luminous intensity is projected toward the reflecting surface 41. The light pattern P1 can be irradiated, and the light distribution pattern AP on the screen can be uniformed in luminous intensity, and the light distribution pattern AP can be formed into a clean rectangular shape.

In addition, the light source device 20 is arranged so that the irradiation optical axis Z2 of the light emitted from the light source 21 is directed obliquely forward and upward, so that the light is condensed toward the light irradiation unit 31 by the reflection surface 41. Therefore, the luminous intensity in the light distribution pattern AP on the screen can be made more uniform, and the light distribution pattern AP can be formed into a clean rectangular shape.

On the other hand, since the light source device 20 and the relay optical section 40 are arranged to be close to the light (see light pattern P3) irradiated from the two-dimensional light control device 30 so as to enter the lens section 50, the size in the vertical direction is reduced. In addition to making it compact and facilitating miniaturization of the vehicle lamp, the generation of glare is firmly prevented by providing a light blocking portion 60 between the two-dimensional light control device 30 and the second lens 22B of the irradiation lens portion 22. It is assumed that it can be suppressed.

Therefore, when the two-dimensional light control device 30 such as a DMD is provided, the vehicular lamp can reduce blurring of the projected image, can be made compact, and can suppress glare.

Although the present invention has been described above based on specific embodiments, the present invention is not limited to the above-described embodiments, and modifications and improvements to the above-described embodiments are also subject to the present invention. It is obvious to those skilled in the art from the description of the claims.
