It is a perspective view which looked at 102 from the rear side.
2 is a partial cross-sectional view taken along the line AA of FIG. 1A, and FIG. 3 shows the decorative member 10, the first light guide body 20, and the vehicle lamp of the vehicle lamp according to the present invention. It is an exploded perspective view which shows the 2nd light guide body 30.

As shown in FIG. 1, the vehicle lighting fixture of the present embodiment is provided so as to be visible from any position 360 ° around the vehicle 102 along the circumference of the vehicle 102 to be mounted, depending on the situation of the vehicle 102. It includes a light emitting region 1 in which the light emitting state is controlled.

In the present embodiment, the light emitting region 1 is provided around the vehicle 102 in a band shape so as to be capable of emitting light, but it is not always necessary that the light emitting region 1 is connected in a band shape and is capable of emitting light. The light emitting portions may be scattered at appropriate intervals, and even in this case, the light emitting region 1 that can be visually recognized from any position of 360 ° around the vehicle 102 can be obtained.

Further, the vehicle lighting equipment of the present embodiment is provided on the front side of the vehicle 102, and includes a front light emitting region 2 in which the light emitting state is controlled according to the situation of the vehicle 102, and is a part of the front light emitting region 2. From now on, it is possible to irradiate a high beam, a low beam, etc. according to the operation of the driver.

Further, the vehicle lighting equipment of the present embodiment includes a rear light emitting region 3 provided on the rear side of the vehicle 102 and controlling the light emitting state according to the situation of the vehicle 102, and the rear light emitting region 3 is at least Some of them function as tail lamps and stop lamps.

The light emitting region 1 is provided so as to extend in the front-rear direction near the lower end of the side window on the left and right sides of the vehicle 102, and on the front side of the vehicle 102, one of the upper outer periphery of the front light emitting region 2. It is provided so as to extend along the portion, and on the rear side of the vehicle 102, it is provided so as to extend along a part of the upper outer periphery of the rear light emitting region 3.

In this way, the visibility can be improved by setting the position where the light emitting region 1 is provided to a higher position.
For example, on the left and right sides of the vehicle 102, if the light emitting region 1 is on the lower end side of the door, the light emitting region is emitted from another vehicle parked next to the vehicle 102 or another vehicle running in parallel with the vehicle 102. Although it is difficult to visually recognize 1, it is possible to visually recognize 1 when it is provided near the lower end of the side window as in the present embodiment.

Further, the light emitting region 1 is easily distinguishable from the front light emitting region 2 and the rear light emitting region 3, and in consideration of the fact that a sharp design can be obtained when the light emitting region 1 is provided along the periphery of the vehicle 102, the vertical direction is obtained. In the present embodiment, the maximum width of the front light emitting region 2 and the rear light emitting region 3 in the vertical direction is 11.0 mm or more, whereas the width of the light emitting region 1 is in the vertical direction. The maximum width of is set to 60.0 mm or less.

In the present embodiment, the width of the light emitting region 1 in the vertical direction is about 50.0 mm at the maximum portion and about 30.0 mm at the minimum portion, and is at any position in the circumferential direction of the vehicle 102. It fits within approximately 30.0 mm or more and 50.0 mm or less.

Further, the width of the portion of the front light emitting region 2 on the left and right side surfaces becomes smaller toward the rear side so that a sense of unity between the light emitting region 1, the front light emitting region 2 and the rear light emitting region 3 can be obtained. At the rear end of the front light emitting region 2, the light emitting region 1 and the front light emitting region 2 are connected without a step, and the shape of the portion on the left and right side surfaces of the rear light emitting region 3 is changed to the front side. The width in the vertical direction is made smaller toward the rear, and the light emitting region 1 and the rear light emitting region 3 are connected without a step at the front end portion of the rear light emitting region 3.

Next, an example of the configuration for causing the light emitting region 1, the front light emitting region 2 and the rear light emitting region 3 to emit light will be described with reference to FIGS. 2 and 3.
In the following description, the configuration on the front side, that is, the configuration of the portion where the ring-shaped light emitting region 1 and the front light emitting region 2 overlap when viewed in the circumferential direction of the vehicle 102 will be described as an example. Since the configuration, that is, the configuration of the portion where the ring-shaped light emitting region 1 and the rear light emitting region 3 overlap when viewed in the circumferential direction of the vehicle 102 is the same configuration, detailed description of the rear side configuration is omitted below. do.

Further, although not shown in FIG. 1, since there are doors on the left and right side surfaces of the vehicle 102, the light emitting region 1 of that portion has a configuration corresponding to the light emitting region 1 described in the front side configuration. Since it is provided only for each, detailed description of the configuration of this part will be omitted below.

As shown in FIG. 2, the vehicle lighting fixture of the present embodiment includes a decorative member 10, a first light guide body 20 whose first exit surface 21 side is arranged close to the decorative member 10, and a second exit surface 31. It includes a second light guide body 30 whose side is arranged close to the decorative member 10 and whose second emitting surface 31 side is arranged close to the first emitting surface 21 side.

In the present embodiment, in the decorative member 10, the inner side surface 12 (the surface facing the first exit surface 21 and the second exit surface 31) of the decorative member 10 substantially contacts the first exit surface 21 and the second exit surface 31. Arranged to do.

The first base portion B1 is arranged inside the first light guide body 20, and the first light guide body 20 is placed on the surface of the first base portion B1 facing the first light guide body 20. A first light emitting unit 25 that irradiates light toward the first incident surface 22 is provided.

The first light emitting unit 25 includes a first substrate 23 and a plurality of first light emitting chips 24 provided on the first substrate 23 along the first incident surface 22, and in the present embodiment, the first light emitting unit 25 includes a first light emitting chip 24. A light emitting element corresponding to the three primary colors of light is packaged in the first light emitting chip 24 so that various light emitting colors can be selected as the light emitting color of the one light emitting unit 25, and an LED capable of emitting three primary colors is used.

In the present embodiment, a plurality of rows of the first light emitting chips 24 provided along the first incident surface 22 are provided in two rows in the vertical direction, but how many rows are provided in the vertical direction is determined. It may be appropriately changed according to the width of the first incident surface 22 in the vertical direction.

Similarly, the second base portion B2 is arranged inside the second light guide body 30, and the second light guide body 30 is placed on the surface of the second base portion B2 facing the second light guide body 30. A second light emitting unit 35 that irradiates light toward the second incident surface 32 of the above is provided.

The second light emitting unit 35 also includes a second substrate 33 and a plurality of second light emitting chips 34 provided on the second substrate 33 along the second incident surface 32. Similar to the first light emitting unit 25, a light emitting element corresponding to the three primary colors of light is packaged in the second light emitting chip 34 so that various light emitting colors can be selected as the light emitting color, and an LED capable of emitting three primary colors is used. ing.

In the present embodiment, a plurality of rows of the second light emitting chips 34 provided along the second incident surface 32 are provided in four rows in the vertical direction, but how many rows are provided in the vertical direction is determined. It may be appropriately changed according to the width of the second incident surface 32 in the vertical direction.

The vehicle lighting fixture of the present embodiment is arranged between the first light guide body 20 and the second light guide body 30, and the light that guides the inside of the first light guide body 20 or the second light guide body 30 is emitted. It has a light blocking unit 40 that suppresses leakage to the second light guide body 30 or the first light guide body 20.

For example, as shown in FIG. 3, the light blocking unit 40 has a light-shielding tape, a light-shielding coating film, a reflective tape, a reflective coating film, and the like between the first light guide body 20 and the second light guide body 30. It can be configured by providing it.

Further, the light blocking unit 40 can also be formed by providing a layer having a refractive index sufficiently lower than that between the first light guide body 20 and the second light guide body 30.
However, when the difference in refractive index is used, the blocking force for blocking light is weaker than that of a tape or paint that physically blocks light. It is preferable to provide a tape, a reflective film of a reflective paint, or the like so as to physically block light.

Then, in the present embodiment, the light blocking unit 40 is provided so as to be in direct contact with both the first light guide body 20 and the second light guide body 30, and the light blocking unit 40 is used as an insert member. By color molding, the light blocking portion 40, the first light guide body 20 and the second light guide body 30 can be integrally molded, and the manufacturing cost can be reduced.

Then, by bringing the light blocking unit 40 into direct contact with both the first light guide body 20 and the second light guide body 30, the light emitting region 1 formed by the light from the first light guide body 20 is formed. And the front light emitting region 2 formed by the light from the second light guide body 30 are not separated, and a good sense of unity can be obtained.

Further, in the present embodiment, the decorative member 10 has a thin thickness of about 3.0 to 3.5 mm, and when light is transmitted through the decorative member 10, the light is emitted without spreading in the vertical direction.
From this, the thickness of the decorative member 10 is preferably 10.0 mm or less, and more preferably 5.0 mm or less.

Further, in the present embodiment, the decorative member 10 is provided so that the distance from the outer surface 11 that irradiates the light forward to the first exit surface 21 and the second exit surface 31 is about 3.5 mm. Light does not spread in the vertical direction from the first exit surface 21 and the second exit surface 31 to the outer surface 11.

Therefore, the state of the light emitted from the outer surface 11 of the decorative member 10 to the front side remains substantially the same as the state of being emitted from the first exit surface 21 and the second exit surface 31 toward the decorative member 10. can do.

In this way, the light is emitted from the decorative member 10 to the front side in a state substantially the same as the state in which the first exit surface 21 and the second exit surface 31 are irradiated toward the decorative member 10. In addition, the decorative member 10 is preferably provided so that the distance from the outer surface 11 that irradiates the light to the front side to the first exit surface 21 and the second exit surface 31 is within 15.0 mm. It is preferably provided so as to be within 10.0 mm, and most preferably it is provided so as to be within 5.0 mm.

Then, when light is irradiated from the first light emitting unit 25 toward the first incident surface 22 of the first light guide body 20, the irradiated light leaks to the second light guide body 30 side by the light blocking unit 40. The inside of the first light guide body 20 is guided so as not to be guided, and the light is irradiated to the front side through the decorative member 10 and is ring-shaped by the light in a state where the color is hardly mixed with the light that guides the second light guide body 30. Light emitting region 1 emits light.

Similarly, when light is irradiated from the second light emitting unit 35 toward the second incident surface 32 of the second light guide body 30, the irradiated light is directed to the first light guide body 20 side by the light blocking unit 40. The inside of the second light guide body 30 is guided so as not to leak, the light is irradiated to the front side via the decorative member 10, and the light in a state where the color is hardly mixed with the light that guides the first light guide body 20 is used for the front. The light emitting region 2 emits light.

Therefore, it is possible to avoid that the color mixing of light occurs at the boundary between the light emitting region 1 and the front light emitting region 2 and the target light emitting color is not obtained.
By configuring the rear light emitting region 3 in the same manner as the front light emitting region 2, it is possible to avoid that the light is mixed at the boundary between the light emitting region 1 and the rear light emitting region 3 and the target light emitting color is not obtained. be able to.

On the other hand, if the decorative member 10 has an internal structure that can be seen through like a so-called outer lens, the light emitting region 1 and the front light emitting region 2 (the same applies to the rear light emitting region 3) do not emit light. The boundary between the light guide body 20, the light blocking unit 40, and the second light guide body 30 becomes visible, and there is no sense of unity.

Therefore, in the present embodiment, the decorative member 10 has transparency capable of transmitting the light emitted from the first emitting surface 21 and the second emitting surface 31, and also has the first light guide body 20 and the light blocking unit 40. When the light emitting region 1 and the front light emitting region 2 (the same applies to the rear light emitting region 3) are not emitting light by assuming that the state of the second light guide body 30 has transparency to the extent that it cannot be seen through. Only the decorative member 10 is visually recognized, and the light emitting regions thereof appear to be integrally formed.

Specifically, the decorative member 10 may be made a color such as milky white or smoked color instead of being colorless and transparent, and may be set to have the above-mentioned transparency depending on the state of color depth.

Alternatively, as another method, a grain or a fine prism is formed on the inner surface 12 (the surface facing the first exit surface 21 and the second exit surface 31) of the decorative member 10, and depending on the state of the grain or the state of the fine prism. , So-called frosted glass-like state, and the transparency may be set as described above.

It is possible to obtain the above-mentioned transparency by forming a grain or a fine prism on the outer surface 11 of the decorative member 10, but if this is done, a rough feeling will be visually recognized, so that the grain or the fine prism will be visually recognized. When the transparency is set by forming, it is preferable to form a grain or a fine prism on the inner side surface 12 of the decorative member 10.

And, as mentioned earlier, since the front light emitting region 2 and the rear light emitting region 3 are not provided in the door portions on the left and right side surfaces of the vehicle 102, this portion is only the light emitting region 1.
Therefore, the light emitting region 1 may be configured by providing the first light guide body 20, the first light emitting unit 25, and the decorative member 10 for each door. In this case, the first light guide body 20 as a whole may be provided. Is arranged in a ring shape along the outer periphery of the vehicle 102 on which the is mounted, and the decorative member 10 is arranged in a ring shape along the first light guide body 20.

Then, if the first light guide body 20 and the decorative member 10 are arranged in a ring shape in this way, the light emitted from the first light guide body 20 toward the decorative member 10 can be emitted from any position around the vehicle 102. Is also visible, and the light emitting region 1 has high visibility.

The decorative member 10 of this portion (door portion on the left and right sides) is not for not showing the boundary between the first light guide body 20, the light blocking portion 40, and the second light guide body 30, but for the front side and the rear. The main purpose is to obtain a sense of unity as a whole by using the same decorative member 10 as the side, and by providing the decorative member 10, the configuration of the first light emitting unit 25 can be visually recognized. It is also possible to avoid.

Next, the control of the light emitting state according to the situation of the vehicle 102 of the vehicle lighting equipment having the above configuration will be described.

(Situation 1)
When the situation of the vehicle 102 is about to start, that is, when the vehicle 102 is stopped, the brake is operating, and the shift state is changed to the drive in the start mode, the light emitting state is displayed. As a control, as shown in FIG. 4, a part C1 excluding the center on the front side of the front light emitting region 2 is controlled to blink.

For example, this blinking control repeats lighting of the first light emission intensity, which is the normal light emission intensity of the front light emission region 2, and lighting of the second light emission intensity, which is higher than the first light emission intensity, several times. It is done by.

That is, instead of repeating turning on and off, the blinking changes the light emission intensity at the time of turning on, and since the light is not turned off, the visibility of the front side of the vehicle 102 is not deteriorated, and the other person ( It is possible to notify pedestrians, drivers of other vehicles, etc.) that the vehicle 102 is about to move.

(Situation 2)
When the situation of the vehicle 102 is a situation in which a pedestrian is urged to cross the front of the vehicle 102, the entire light emitting area 1 is blinked as a control of the light emitting state, and the front light emitting area 2 is shown as shown in FIG. (Refer to the black-painted part), for example, when a pedestrian crosses from the right side to the left side of FIG. ... → DN is controlled to move in the transverse direction.

Therefore, not only the pedestrian is strongly impressed that the vehicle 102 is stopped by the entire blinking of the light emitting region 1, but also the pedestrian is stopped by controlling the light emitting state of the front light emitting region 2. It is possible to accurately inform the pedestrian that it is a stop for crossing the road first.

For example, such control of the light emitting state may be performed by the operation of the driver. Recently, since the vehicle 102 is equipped with a camera, a sensor for detecting a person, or the like, the vehicle 102 controls a pedestrian. It is also possible to have the control unit obtain the fact that the vehicle has stopped in order to cross the vehicle from the image of the camera, the value of the sensor, or the like, and automatically perform the operation.

(Situation 3)
When the situation of the vehicle 102 is a situation where there is a pedestrian who is stopped on the shoulder of the road and is crossing the front of the vehicle 102, as a control of the light emitting state, for example, in the figure of the vehicle 102 on the left side of FIG. When a person is crossing from the right side to the left side, it is located on the opposite side (the left side of the left figure of FIG. 6 and the right side of the right figure of FIG. 6) to the crossing start side of the pedestrian (the right side of the left figure of FIG. 6). Control is performed to blink a part C3 of the front light emitting area 2 on the side and a part C3 of the rear light emitting area 3.

Specifically, as the blinking control at this time, in the front light emitting region 2, lighting and extinguishing at the first light emitting intensity, which is the normal light emitting intensity of the front light emitting region 2, are repeatedly performed, and in the rear light emitting region 3, the rear light emitting region 3 is used. The rear light emitting region 3 is repeatedly turned on and off at the third light emitting intensity, which is the light emitting intensity of the tail lamp in the normal state.

In this way, by notifying the following vehicle or the like that there is a pedestrian trying to cross the front of the vehicle 102, it is possible to prevent an accident due to the pedestrian jumping out from the shadow of the vehicle 102.

For example, such control of the light emitting state may be performed by the operation of the driver, and the image of the camera or the value of the sensor may be used by using a camera mounted on the vehicle 102, a sensor for detecting a person, or the like. For example, the control unit may be asked to request the situation and the situation may be automatically performed.

(Situation 4)
When the situation of the vehicle 102 is a situation in which a following vehicle is approaching, as a control of the light emitting state, a control of blinking the entire rear light emitting region 3 that emits light so as to function as a tail lamp is performed.
It should be noted that the entire rear light emitting region 3 does not necessarily have to blink, and at least a part of the rear light emitting region 3 may be controlled to blink.

For example, lighting at the third emission intensity, which is the emission intensity of the rear light emitting region 3 as a normal tail lamp, and emission higher than the third emission intensity and lower than the fourth emission intensity, which is the emission intensity as a stop lamp. Blinking control is performed so as to repeat the lighting of the fifth emission intensity, which is the intensity.

Then, in the blinking control, the blinking speed is changed based on the distance and speed of the following vehicle.
Specifically, a collision prevention alert is issued by changing the blinking speed so that the blinking speed becomes faster as the speed of the following vehicle is faster and the distance is shorter.

For example, in such control of the light emitting state, the distance and speed of the following vehicle are obtained from the control unit from the value of the sensor by using a sensor or the like that measures the distance between the following vehicle and the following vehicle mounted on the vehicle 102. It should be done automatically.

(Situation 5)
When the vehicle 102 is parked in the automatic mode, as a control of the light emitting state, the entire light emitting area 1 is blinked at a blinking cycle having a high blinking speed like a so-called hazard lamp, and is shown in FIG. As described above, the control is performed so that a part C5 on the left and right center side of the rear light emitting region 3 is made to emit light in a light emitting color other than red (for example, white).

The entire light emitting area 1 is not limited to blinking, and at least a part thereof may be blinked. However, by blinking the entire light emitting area 1, it is suitable for others all around the vehicle 102. Since it is possible to notify, it is preferable to blink the entire light emitting region 1.

Further, by causing a part of the rear light emitting region 3 on the left and right center side to emit light in a light emitting color other than red (for example, white), the rear light emitting region 3 that emits red light generally emits light in a different color. , It is easy for others on the rear side of the vehicle 102 to recognize that the vehicle 102 is moving backward.

For example, such control of the light emitting state may be performed based on the operation of parking in the automatic mode by the driver.

A part of the area C8 corresponding to the pedestrian is blinked according to the distance and the angle of the person, and the blinking part is moved according to the pedestrian. Control is done.

For example, blinking control in which lighting at the sixth emission intensity, which is the normal emission intensity of the light emitting region 1, and lighting at the seventh emission intensity, which is a emission intensity higher than the emission intensity of the sixth emission intensity, are repeated. Should be done.

Then, as described above, the blinking portion of the area C8 is made to move corresponding to the pedestrian according to the relative angle between the vehicle 102 and the pedestrian.

For example, such control of the light emitting state is performed by using a camera mounted on the vehicle 102, a sensor for detecting a person, or the like, and the control unit detects a person from the image of the camera, the value of the sensor, or the like. The blinking control of the position corresponding to the person is started according to the distance and angle between the 102 and the person, and the control unit is made to obtain the relative angle between the vehicle 102 and the person, and the area C8 is adjusted to the change of the relative angle. Of these, the blinking part may be moved, that is, the movement may be controlled in response to a pedestrian.

(Situation 9)
When the situation of the vehicle 102 is a situation where the door is opened, as a control of the light emitting state, for example, when the door on the left side of the vehicle 102 is opened, as shown in FIG. 10, the door to be opened in the light emitting region 1 Control is performed to blink the area C9 from the front end of the area corresponding to (the left door) to a position visible from the rear side.

Specifically, the region C9 is lit in a stepping stone state at the sixth emission intensity, which is the normal emission intensity of the light emission region 1, and the seventh emission intensity, which is higher than the emission intensity of the sixth emission intensity. After lighting the part to be lit so that there is, the part lit with the 6th emission intensity is lit with the 7th emission intensity, and the part lit with the 7th emission intensity is lit with the 6th emission intensity. It is advisable to make the lighting state blink in the stepping stone state.

For example, such control may be performed based on the fact that a sensor such as a touch sensor is provided on the doorknob and a person in the vehicle 102 touches the doorknob.

(Situation 10)
When the situation of the vehicle 102 is a situation where security is started, for example, when security is started such as when the door is locked, a part of the light emitting area 1 is turned on and a part of the light emitting area 1 is turned on as a control of the light emitting state. Control is performed to move the lighting portion so as to orbit the light emitting region 1.
For example, such control may be based on locking the door.

As described above, in the vehicle lighting equipment of the present embodiment, unlike the conventional lighting equipment, the light emitting region 1 is provided so as to be visible from any position of 360 ° around the vehicle 102, so that another person (walking). People, drivers of other vehicles, etc.) can easily recognize the transmitted information, and information can be transmitted according to various situations of the vehicle 102, so that communication with others is high. ..
