[ 1 st embodiment ]
First, the mirror unit 100 including the motor 10 for a mirror in embodiment 1 will be described.
Fig. 1 is a diagram schematically showing the configuration of a motor 10 for a mirror reflector constituting embodiment 1 of a mirror unit 100. Fig. 2 is a plan view showing a schematic structure of the mirror 17 according to embodiment 1. Fig. 3A is a cross-sectional view taken along line B-B of fig. 2, and is a side view showing the 2 nd reflecting surface 172 of the mirror 17 of embodiment 1. Fig. 3B is a sectional view taken along line C-C of fig. 2, and is a side view showing the 3 rd reflecting surface 173 of the mirror 17 of embodiment 1. Fig. 4 is a perspective view showing another shape of the mirror.
The mirror device 100 shown in fig. 1 is composed of the motor 10 for a mirror of the present embodiment, a light source unit 80, and a case 1001 housing the motor 10 for a mirror and the light source unit 80.
The light source unit 80 emits light toward the motor 10 for the mirror. The light source unit 80 includes: a heat sink, not shown, fixed to case 1001; a light source 83 mounted on a side surface of the heat sink 81 via the substrate 82; and a lens 84 disposed between the light source 83 and the motor 10 for the mirror in the light emitting direction of the light source 83.
As the light source 83, a plurality of semiconductor light emitting elements such as LEDs, LDs, and EL elements are preferably used. The light source 83 outputs light that is vertically long in the axial direction of the mirror device 100 by a plurality of semiconductor light emitting elements that are arranged, for example, in the vertical direction (axial direction) of the mirror device 100. The lens 84 condenses the light emitted from the light source 83 toward the motor 10 for the mirror reflector. The light source unit 80 has a function of controlling irradiation (light shielding) to the motor 10 for the mirror described later.
The motor 10 for the mirror reflector reflects the light emitted from the light source unit 80 in a direction different from the direction of the light source unit 80 (forward of the mirror unit 100). The motor 10 for a mirror has: a rotation driving unit 13 that rotates about a central axis O; a shaft 14 that rotates together with the rotation driving unit 13; and a mirror (reflecting member) 17 connected to one side in the axial direction of the shaft 14.
The mirror 17 rotates about the center axis O together with the shaft 14 in accordance with the driving of the rotation driving unit 13. The central axis O is sometimes also referred to as a rotation axis of the rotation driving portion 13. The mirror 17 has a substantially triangular prism shape having a triangular upper surface 174, a bottom surface 175, and three reflecting surfaces 170 around the central axis O when viewed from the axial direction.
Further, although the mirror 17 of the present embodiment has a shape having the upper surface 174 and the bottom surface 175, as long as at least three reflection surfaces 170 are provided in the circumferential direction, the mirror may not have the upper surface 174 and the bottom surface 175, and may have a space inside. In the present specification, the "polygonal column shape" may be any column shape having a polygonal outer shape in a cross section intersecting with the axial direction, and includes a solid shape, a hollow shape, and a cylindrical shape.
The mirror 17 is positioned on the optical axis of the lens 84 of the light source unit 80, and the reflecting surfaces 170 are sequentially moved on the optical axis of the light source unit 80 as the mirror 17 rotates. Each reflecting surface 170 reflects light emitted from the light source unit 80 in a direction different from the incident direction and forward (G direction) of the mirror device 100.
As shown in fig. 2, 3A, and 3B, the three reflecting surfaces 170(171, 172, 173) of the mirror 17 have different angles with respect to the central axis O. In embodiment 1, the 1 st reflecting surface 171 is a surface parallel to the central axis O with an inclination angle of 0 ° with respect to the central axis O. The 2 nd reflecting surface 172 and the 3 rd reflecting surface 173 (2 nd reflecting surface) are inclined with respect to the central axis O and have different angles with respect to the central axis O. The 2 nd reflecting surface 172 is inclined at a predetermined angle- θ (fig. 3A) with respect to the central axis O, and the 3 rd reflecting surface 173 is inclined at a predetermined angle + θ (fig. 3B) with respect to the central axis O. In the present embodiment, the absolute values of the inclinations | θ | are equal, but may be different. In addition, the inclination directions with respect to the central axis O may be the same.
For example, the 2 nd reflecting surface 172 is an upper reflecting surface facing upward with respect to the 1 st reflecting surface 171, and can be visually confirmed when viewed from the upper surface 174 of the mirror 17 as shown in fig. 3A. The 3 rd reflecting surface 173 is a downward reflecting surface facing downward with respect to the 1 st reflecting surface 171, and is blocked by the upper surface 174 of the mirror 17 and cannot be seen when viewed from the upper surface 174 as shown in fig. 3B.
The reflection surfaces 171 to 173 are side surfaces of triangular prisms, and are rectangular flat surfaces that are smooth as a whole. In the present embodiment, the long side of each reflecting surface 170 is substantially perpendicular to the central axis O, and the short side is substantially parallel to the central axis O.
As shown in fig. 1, the length of each reflecting surface 170 in the circumferential direction (around the central axis O) of the mirror 17, that is, the length of the long side of each reflecting surface 170 is longer than the width of the incident light incident on the reflecting surface 170 in the circumferential direction. Here, the width of the incident light is the lateral width of the vertically long light emitted from the light source 83 toward the mirror motor 10, and is the width of the light in the direction perpendicular to the vertical direction of the mirror 17.
In the mirror unit 100 described above, the light emitted from the light source unit 80 and reaching the mirror 17 of the mirror motor 10 is reflected by each of the reflecting surfaces 170, and is reflected in a direction different from the direction in which the light enters each of the reflecting surfaces 170 and in front of the mirror unit 100 (the G direction: fig. 1). At this time, since the mirror 17 is rotated about the central axis O by the driving of the rotation driving unit 13, when the light emitted from the light source unit 80 enters the respective reflection surfaces 170 having different angles with respect to the central axis O, the incident light is reflected at an angle corresponding to the rotational position of the respective reflection surfaces 170 that are rotated, and the light is scanned in the left-right direction (direction F: fig. 1).
The mirror unit 100 can be used as a vehicle lamp mounted on a headlamp of a vehicle. The vehicle lamp having the mirror unit 100 can improve not only the visibility in the horizontal direction but also the visibility in the vertical direction in the front of the vehicle, for example, by using the light emitted from each reflecting surface 170 of the motor for mirror 10.
Specifically, in the mirror device 100, the light incident on the 1 st reflecting surface 171 parallel to the central axis O in the mirror 17 in the triangular prism shape is reflected forward of the mirror device 100, and is scanned at the height of the driver's sight line, for example, in the horizontal direction by the rotation. This makes it possible to illuminate the vehicle front brightly.
Since the mirror 17 of the present embodiment includes the 2 nd reflecting surface 172 and the 3 rd reflecting surface 173 having different angles with respect to the central axis O in addition to the 1 st reflecting surface 171 parallel to the central axis O, when the irradiation position of the 1 st reflecting surface 171 is set to the height of the line of sight of the driver (front surface), the irradiation position of each of the reflecting surfaces 172 and 173 is located above the height of the line of sight of the driver.
That is, light incident on the 2 nd reflecting surface 172 inclined upward with respect to the 1 st reflecting surface 171 (central axis O) is reflected upward than light reflected by the 1 st reflecting surface 171 (hereinafter referred to as 1 st irradiation light), and is rotated to scan in the horizontal direction at a position above the front surface. Thus, the irradiation position of the reflecting surface 172 is located above the height of the driver's line of sight.
Light incident on the 3 rd reflecting surface 173 inclined downward with respect to the 1 st reflecting surface 171 (central axis O) is reflected downward than the 1 st illumination light reflected by the 1 st reflecting surface 171, and is rotated to scan in the horizontal direction at a position below the front surface. Thus, the irradiation position of the reflecting surface 173 is lower than the height of the line of sight of the driver.
In the mirror 17 of the present embodiment, since the space above the height of the line of sight of the driver can be illuminated by the reflected light reflected by the 2 nd reflecting surface 172 facing upward with respect to the 1 st reflecting surface 171, a signal, a notice board, or the like located at a high position can be brightly illuminated. Further, the reflected light reflected by the 2 nd reflecting surface 172 directed downward with respect to the 1 st reflecting surface 171 can illuminate a space below the height of the line of sight of the driver, and thus can illuminate a road surface near the vehicle brightly. This makes it possible to confirm an abnormality of the lane that becomes a travel obstacle, such as a falling object or a damage of the road surface.
Further, by turning ON and OFF the light emission of the light source unit 80 according to the position of each reflecting surface 170, the irradiation of the reflected light can be controlled according to the situation in front of the vehicle. For example, in the case where there is a preceding vehicle, an oncoming vehicle, or the like, by turning OFF only the light incident on the 1 st reflecting surface 171, it is possible to suppress the irradiation of light to the front side while irradiating the upper and lower sides, and to make other drivers less likely to feel dazzling.
For example, when the driver's seat of the preceding vehicle or the oncoming vehicle is high, only the light incident on the 2 nd reflecting surface 172, which is the upward inclined surface, is turned OFF, and only the upward irradiation is suppressed, so that the irradiation can be performed within a range that does not interfere with the driving of other drivers.
Further, for example, during traveling ON an upward or downward slope, irradiation of the preceding vehicle can be suppressed by controlling ON and OFF of light incident ON the 2 nd reflecting surface 172 and the 3 rd reflecting surface 173 in accordance with the timing of irradiation ON the upward or downward direction.
Therefore, by individually controlling ON and OFF of the light incident ON each reflecting surface 170 of the mirror 17 in the motor 10 for a mirror reflector according to the present embodiment, it is possible to perform high-definition light distribution, irradiate light in a desired direction without causing glare to other drivers, and improve visibility in the front of the vehicle. Thus, a headlamp capable of comfortable and smooth operation can be realized.
In the mirror device 100, the vertical position of the scanning reflected light can be appropriately changed by appropriately setting the respective inclination angles of the respective reflection surfaces 171, 172, 173 with respect to the central axis O of the motor 10 for the mirror.
Further, since the reflection surface 170 is substantially parallel to the shaft 14, even if the reflection surface 170 moves in the axial direction together with the shaft 14 due to the influence of an external force or the like, the influence of the reflected light on the irradiation position can be suppressed. Further, since the mirror 17 can be reduced in the radial direction, the inertia around the shaft 14 is reduced, and the acceleration at the time of startup can be increased.
In addition, conventionally, since irradiation in a predetermined direction is restricted by controlling the number of lighting of a plurality of light sources arranged in the vertical direction, when the light emission of several light sources is suppressed in order to suppress irradiation to an oncoming vehicle, irradiation in a direction in which visual confirmation is desired may be lost. In contrast, in the present embodiment, since the directions of the three reflecting surfaces 170 are such that the irradiation directions of the upper, front, and lower sides can be appropriately controlled, light blocking in a narrow range can be realized, and irradiation of the oncoming vehicle can be suppressed and a desired range can be irradiated even with a small number of light sources. This can reduce the number of vertically arranged semiconductor light emitting elements, and can reduce the size, weight, and power consumption of the light source 83.
The structure of the mirror 17 is not limited to the above-described structure, and may be appropriately changed. For example, the shape of the mirror 17 is not limited to the triangular prism shape described above, and may be, for example, a substantially triangular pyramid shape. In this case, the mirror device 100 can be downsized. The shape of the mirror 17 may be other polygonal shapes such as a pentagonal prism, a quadrangular prism, and a hexagonal prism shown in fig. 4. In this case, four or more reflection surfaces are provided around the central axis O, and at least one of the reflection surfaces 170 is the 1 st reflection surface 171, and the other reflection surfaces 170 are the 2 nd reflection surfaces 172 and 173. The ratio of the number of the 1 st reflecting surface 171, the 2 nd reflecting surface 172, and the 3 rd reflecting surface 173 is appropriately set according to the shape of the polygonal column. The slopes of the reflective surfaces 170 of the polygonal prisms may all be different.
(modification 1)
Fig. 5A is a diagram showing the structure of the mirror 27 of modification 1.
In the above embodiment, all of the three reflecting surfaces 170 of the triangular prism-shaped reflecting mirror 17 have a planar shape, but as in the reflecting mirror 27 shown in fig. 5A, at least one of the three reflecting surfaces 270 may be a concave reflecting surface 271 recessed toward the center axis O side, and the other two reflecting surfaces 270 may be reflecting surfaces 272 formed to be planar surfaces.
In the case of a mirror shape having a triangular prism shape, the reflecting surfaces 170 are arranged at intervals of 120 degrees around the axis. Therefore, although a range of about 240 degrees can be scanned in the horizontal direction by the reflection surface 170 formed in a flat surface, depending on the use conditions, it may be sufficient that the irradiation range is a range narrower than 240 degrees, for example, about 120 degrees. In such a case, the irradiation range can be narrowed by forming the mirror shape having the reflecting surface 271 formed of a concave surface as in this example.
In the modification 1, one reflecting surface 270 of the three reflecting surfaces 270 of the mirror 27 is a surface parallel to the central axis O, and the remaining two reflecting surfaces 270 are surfaces inclined at different angles from each other with respect to the central axis O, and for example, the other two reflecting surfaces 271 are inclined upward or downward with respect to the reflecting surfaces 270 parallel to the central axis O.
(modification 2)
Fig. 5B is a diagram showing the structure of the mirror 28 of modification 2.
As in the mirror 28 shown in fig. 5B, at least one of the three reflecting surfaces 280 may be a convex reflecting surface 281 protruding in a direction away from the center axis O (outward), and the other two reflecting surfaces 280 may be reflecting surfaces 282 formed as flat surfaces.
In this example, the irradiation range can be further expanded. In particular, in the case of a pentagonal prism or a hexagonal prism, the irradiation range of the planar reflector is narrowed. In such a case, the irradiation range can be enlarged by forming the reflector shape having the reflecting surface 280 formed of a convex surface as in this example.
In the modification 2, one of the three reflecting surfaces 280 is a surface parallel to the central axis O, and the remaining two reflecting surfaces 280 are surfaces inclined at different angles with respect to the central axis O, and for example, the other reflecting surfaces 280 are inclined upward or downward with respect to the reflecting surfaces 280 parallel to the central axis O.
[ 2 nd embodiment ]
Next, the motor 20 for a mirror reflector according to embodiment 2 will be described.
Fig. 6 is a perspective view showing a schematic configuration of the motor 20 for a mirror reflector according to embodiment 2.
As shown in fig. 6, the motor 20 for a mirror of the present embodiment includes a mirror 29, and at least one reflecting surface 290 of the mirror 29 has wide-angle reflection characteristics.
For example, at least one reflection surface 291 of the three reflection surfaces 290 existing around the axis of the mirror 29 in the shape of a triangular prism has the wide-angle reflection section 31.
The wide-angle reflection unit 31 reflects incident light toward a plurality of surfaces along the circumferential direction of the 1 st reflection surface 291, and the wide-angle reflection unit 31 is positioned at the center in the axial direction of the 1 st reflection surface 291. The wide-angle reflection unit 31 is formed of a plurality of wide-angle reflection surfaces 310 arranged in 1 row along the long side of the 1 st reflection surface 291, and the plurality of wide-angle reflection surfaces 310 are provided at predetermined intervals from each other in the entire longitudinal direction (circumferential direction) of the 1 st reflection surface 291. Each wide-angle reflecting surface 310 has a rectangular shape in plan view, and the long side thereof is arranged in a direction substantially along the rotation axis O.
The wide-angle reflecting part 31 may be provided on any reflecting surface 290 of the reflecting surface 290 parallel to the central axis O and the remaining pair of reflecting surfaces 290 inclined at different angles from each other with respect to the central axis O. As described above, the present invention is not limited to one surface, and may be provided on both surfaces or all surfaces. In addition, the wide-angle reflection unit 31 is arranged only in 1 row with respect to the reflection surface 290, but may be arranged in a plurality of rows. The number, plan view shape, arrangement pitch, and the like of the wide-angle reflecting surfaces 310 are not limited to those shown in fig. 6, and may be appropriately changed.
According to the motor 20 for a mirror of the present embodiment, a part of the irradiation light can be diffused widely in the scanning direction by the wide-angle reflection unit 31 provided on each reflection surface 290. Thus, the irradiation region can be irradiated with brightness at which other drivers such as oncoming vehicles are less likely to feel dazzling, so that the drivers can travel more comfortably, and the instantaneous images of photographs, a drive recorder, and the like can be captured with high image quality, so that the situation in front of the vehicle at the time of capture can be confirmed.
While one embodiment of the present invention has been described above, the configurations and combinations thereof in the embodiment are examples, and additions, omissions, substitutions, and other changes in the configurations can be made without departing from the scope of the present invention. The present invention is not limited to the embodiments.
