Description

  The present invention relates to a vehicle interior indirect lighting device that illuminates a vehicle interior with indirect light.

Conventionally, various lighting devices have been proposed and put into practical use in order to illuminate the interior of a vehicle, which is a vehicle living space.
The simplest example of the vehicle interior lighting device is one in which a vehicle interior lamp is attached to the ceiling of the vehicle interior and the vehicle interior is directly illuminated by the vehicle interior light.
On the other hand, Patent Document 1 proposes a technique in which light from a light source is guided to a lighting device formed in a line shape with a transparent material via a light transmission hose, and light is diffused in a line shape by the lighting device to emit light. ing. According to this, many areas can be illuminated with one light source. Moreover, even if the light source is a point light source, the light emission area can be increased, for example, light can be emitted in a line shape.

As another example of a vehicle interior lighting device, in order to improve the comfort in the vehicle interior, the light from the light source (direct light) is applied to the wall surface of the vehicle interior, the light shielding member of the illumination device, etc. An illuminating device (indirect illuminating device for vehicle interior) using an indirect illumination system that illuminates the vehicle interior with diffused indirect light has been proposed.
Generally, by illuminating the passenger compartment with indirect light, it is possible to create an environment in which passengers can relax.

There are various types of light sources used in vehicle interior lighting devices, and white light bulbs are used as general light sources. In addition, a light emitting diode element (LED) may be used as a light source because it is relatively inexpensive and has relatively high light emission efficiency for low power consumption and excellent durability.

By the way, in order to improve the design of the vehicle interior, it is preferable that the vehicle interior illumination device to be attached to the vehicle interior can be selected from a variety of options. Is required.
As one proposal of such various types of illumination devices, an indirect illumination device that performs indirect illumination using a linear light source that emits light in a line shape is required.

However, the indirect illumination device using a line light source has the following problems.
In the case of an indirect illumination device using a linear light source, it is conceivable to use a linear light source such as a fluorescent lamp as the light source device. In this case, however, power consumption becomes larger than that of an LED or the like. In addition, when a fluorescent lamp is used, a large load is applied at the time of lighting, and there is a disadvantage that a large load is applied to the circuit system.

In addition, when an LED is used as a light source device, since the LED is a point light source, it is necessary to increase the number of LEDs, such as arranging a plurality of LEDs in a line shape in order to emit light in a line shape. It leads to increase.
In addition, it is conceivable to apply the technique of Patent Document 1 so that light is guided from a point light source such as an LED to a transparent material formed in a line shape and emitted from the transparent material in a line shape.

However, when the technique of Patent Document 1 is applied to an indirect illumination device, it is possible to use a light source as a line light source, but light is emitted in all directions as diffused light from a transparent material that is a light source. A large amount of light is blocked by the light blocking plate for blocking the direct light to the occupant.
For this reason, in order to obtain indirect light, when illuminating interior members such as the wall surface of the passenger compartment, the illuminance on the irradiated surface is significantly reduced with respect to the amount of light from the light source to obtain sufficient illuminance as an indirect lighting device. I can't. Moreover, in order to obtain sufficient illuminance, it is necessary to use a light source with higher output, which increases cost and power consumption.

In particular, in the case of indirect illumination, in order to obtain sufficient illuminance, the light source needs to have a higher output than in the case of direct illumination. For this reason, it is desired to suppress an increase in the output of the light source as much as possible in indirect illumination.
The present invention was devised in view of such problems, so that sufficient intensities can be obtained while suppressing the power consumption of the light source as much as possible in the indirect lighting device for a vehicle interior using a linear light source as a light source. An object of the present invention is to provide a vehicle interior indirect lighting device.

The garnish and the convex portion are formed along the vehicle width direction .

Also, by irradiating the light directly into the interior of the garnish, it is conceivable to illuminate the vehicle interior by the light reflected and diffused into the garnish. The interior member in the vehicle interior that directly irradiates light preferably has a diffusion surface that diffuses light.
In addition, as a light source, illuminating devices, such as a light emitting diode (LED) and a light bulb, can be considered.

Further, in order to facilitate the mounting of the reflecting member, it is conceivable that the cross section of the light emitting member is formed in a shape parallel to the central axis and a part of a circle is cut out, and the reflecting member is provided on this notched surface. .

An edge extending from the front end of the garnish toward the mounting surface is formed at the front end of the garnish, and the edge blocks direct light emitted from the light source to the room mirror. Therefore, it is preferable that the edge portion is configured as the direct light suppressing member (claim 2 ) .

In addition, it is also conceivable to use the edge portion and the convex portion in combination as a direct light suppression member.

As shown in FIGS. 2 and 3, the vehicle 1 is provided with indirect lighting devices (hereinafter referred to as lighting devices) 3 and 4 of the present invention at two front and rear locations.
Three rows of seat groups are installed in the vehicle compartment 2 that is the indoor space of the vehicle 1, and the front row seat 12, the second row seat 13 and the third row seat 14 are arranged in parallel from the front. The front illumination device 3 is installed behind and above the front row sheet 12, and the rear illumination device 4 is installed behind and above the second row sheet 13.

A windshield 11 that forms a part of the front surface of the compartment 2 is provided in front of the compartment 2, and a rearview mirror 5 for the driver's rear view is attached near the upper center of the windshield 11. ing.
An instrument panel 16 is installed below the room mirror 5, and an illumination switch panel 15 is provided on the instrument panel 16.

The lighting switch panel 15 is provided with a dial type switch 15A that can change the light quantity of each of the lighting devices 3 and 4 steplessly. By rotating the dial type switch 15A, each of the lighting devices 3 and 4 is rotated. On / off and the amount of light of each of the lighting devices 3 and 4 can be set steplessly.
The lighting devices 3 and 4 are each formed in a strip shape that is long in the left-right direction (hereinafter referred to as the vehicle width direction) of the vehicle 1, and each has a roof lining (mounting surface, interior member) 6 that forms the upper surface of the passenger compartment 2. They are arranged in parallel in the front-rear direction (hereinafter referred to as the vehicle length direction) at a predetermined interval.

As shown in FIG. 3, front pillars 7 and 8, which are structural members of the vehicle 1, are installed at the ends of the lighting device 3 extending from the left and right ends along the roof lining 6. Rear pillars 9 and 10 are installed at the ends of the left and right ends extending along the roof lining 6.
In other words, the installation positions of the lighting devices 3 and 4 in the vehicle length direction are set to substantially the same positions as the front pillars 7 and 8 and the rear pillars 9 and 10, respectively. Further, the dimension (band width) in the vehicle length direction of each of the lighting devices 3 and 4 is substantially the same as the dimension in the vehicle length direction (the pillar width dimension) of the front pillars 7 and 8 and the rear pillars 9 and 10, respectively. Is set.

From such an arrangement of the lighting devices 3 and 4 and the pillars 7 to 10, it is possible to give a sense of unity and continuity to the lighting devices 3 and 4 and the left and right pillars 7 to 10 on both ends thereof. The design can be such that these members are an integral structural member.
Next, the detailed structure of each illuminating device 3 and 4 is demonstrated. Note that. Since the illuminating device 3 and the illuminating device 4 are configured in the same manner, only the configuration of the illuminating device 3 will be described here, and a detailed description of the illuminating device 4 will be omitted.

As shown in FIGS. 1 and 4, the lighting device 3 includes a light source unit 20 that is mounted apart from a mounting surface inside the passenger compartment 2 and a garnish 21 as a light shielding member. 20 includes a pair of light emitting members (acrylic bars) 22 and 23 and four light source devices 24 to 27.
The garnish 21 has a strip-shaped bottom portion 21A that is long in the vehicle width direction, an edge portion 21B that extends obliquely upward from the front end portion of the bottom portion 21A, and an edge portion 21C that extends obliquely upward from the rear end portion of the bottom portion 21A. ing.

Further, the garnish 21 is formed of an impermeable resin or the like that blocks light, and as will be described later, a part of the direct light radiated from each of the light radiating members 22 and 23 has a bottom 21A and an edge of the garnish 21. The parts 21B and 21C are shielded.
The garnish 21 is fixed to the roof lining 6 with a predetermined gap from the roof lining 6 by a bolt or the like (not shown).

  The light source devices 24 to 27 are disposed adjacent to the left and right ends of the light emitting members 22 and 23, respectively. The light source devices 24 and 25 are directed in the axial direction (inward in the vehicle width direction) of the light emitting member 22 so that light is incident from the left and right end surfaces of the light emitting member 22, respectively. In order to allow light to enter from the left and right end surfaces of the radiating member 22, the light radiating member 22 is directed in the axial direction (in the vehicle width direction).

Each of the light source devices 24 to 27 is a light emitting diode (LED) lighting device, and incorporates LEDs 24A to 27A as light sources, respectively.
The light source devices 24 to 27 are connected to a dial switch 15A of the illumination switch panel 15 and a power source (not shown) by wiring (not shown). ˜27A is energized, and the LEDs 24A˜27A built in the light source devices 24˜27 emit light with a set light amount.

  Each of the pair of light emitting members 22 and 23 is an elongated rod-like member formed of an acrylic resin having a light transmitting property and extending parallel to the vehicle width direction. The light emitting member 22 is an edge of the garnish 21. The light emitting member 23 is disposed on the bottom 21A via the plurality of mounting tables 29 on the bottom 21A in proximity to the edge 21C. ing.

Each of the light emitting members 22 and 23 is formed to have a cross-sectional shape in which a part of a circle is cut out by a plane parallel to the central axis (coincident with the vehicle width direction), and is formed by a circular notch. It has planar cut-out surfaces 22A and 23A and curved radiation surfaces 22B and 23B corresponding to the arc portions of the cross section.
Reflecting members 30 and 31 for reflecting light are attached to the notched surfaces 22A and 23A in parallel to the central axes of the light emitting members 22 and 23, respectively. By forming the planar cutout surfaces 22A and 23A on the light emitting members 22 and 23, the reflecting members 30 and 31 can be easily attached. The reflecting members 30 and 31 preferably reflect light at a high rate, and preferably reflect light totally or substantially totally.

The light emitting members 22 and 23 are oriented so that the direction (normal direction) perpendicular to the respective notch surfaces 22A and 23A is substantially parallel to the vehicle length direction, and the two notch surfaces 22A and 23A are arranged so as to face each other, so that the notch surfaces 21A and 22A face the gaps between the edge portions 21B and 21C of the garnish 21 and the roof lining 6.
On the other hand, above the passenger compartment 2, as shown in FIG. 1, the roof lining 6 on the front side of the lighting device 3 smoothly protrudes downward (that is, toward the garnish 21 of the lighting device 3). Part 6A is formed.

The height of the convex portion 6 </ b> A of the roof lining 6 is set so as to be positioned on an imaginary line P connecting the upper end of the light emitting member 22 and the lower end of the room mirror 5. And the direct light irradiated with respect to the windshield 11 is interrupted | blocked.
This is because when the roof lining 6 is formed flat, direct light from the light radiating member 22 of the lighting device 3 is reflected on the room mirror 5 or the windshield 11. This is because there was a request to suppress the reflection of direct light.

Further, the convex portion 6A of the roof lining 6 is formed longer in the vehicle width direction than the length of the light emitting member 22A in the vehicle width direction.
In addition, the convex part of roof lining 6 is not provided in the back part rather than the illuminating device 3 including the vicinity of the illuminating device 4. FIG.

Since the vehicle interior indirect lighting device according to the embodiment of the present invention is configured as described above, the following operations and effects are achieved.
First, the operation of the vehicle interior indirect lighting device of the present invention will be described focusing on the front side lighting device 3.
When the illuminating device 3 is turned on by operating the dial switch 15A of the illuminating switch panel 15 and the illuminating device 3 is set to an appropriate amount of light, the LEDs 24A to 24A built in the light source devices 24 to 27 in the illuminating device 3 are provided. When a voltage corresponding to the set light amount is applied to 27A and energized, the LEDs 24A to 27A emit light. As the LEDs 24A to 27A emit light, light from the LEDs 24A to 27A is incident from the left and right ends of the light emitting members 22 and 23 in a direction substantially along the axial direction of the light emitting members 22 and 23.

When light is incident on the light emitting members 22 and 23, most of the incident light is transmitted in the axial direction inside the light emitting members 22 and 23.
On the other hand, as shown in FIG. 5, part of the incident light is radiated to the outside from the curved radiation surfaces 22B and 23B of the light radiation members 22 and 23. Further, another part of the incident light reaches the notched surfaces 22A and 23A of the light emitting members 22 and 23, and is reflected by the reflecting members 30 and 31 provided on the notched surfaces 22A and 23A. , 23.

  In this way, incident light incident on the light emitting members 22 and 23 is reflected by a subtle error in incident angle at the time of incidence, light refraction caused by this, or impurities inside the light emitting members 22 and 23. The light is emitted from the radiation surfaces 22B and 23B of the light emitting members 22 and 23 to the outside of the light emitting members 22 and 23 while being transmitted in the axial direction through the light emitting members 22 and 23 by diffusion or the like.

The amount of light emitted from the radiation surfaces 22B and 23B can be adjusted by changing the material of the reflecting members 30 and 31 and the vertical dimension.
In this way, incident light incident from both ends of the light emitting members 22 and 23 by the light source devices 24 to 27 is emitted from the radiation surfaces 22B and 23B, so that the light emitting members 22 and 23 are lined over the entire length. It becomes a linear light source that emits light.

In addition, since the radiation | emission surfaces 22B and 23B of the light radiation members 22 and 23 are formed in circular arc shape, the light radiated | emitted from radiation surfaces 22B and 23B turns into light which has moderate diffusivity.
Further, light (direct light) emitted from the light emitting members 22 and 23 is applied to the roof lining 6 through the gaps between the edge portions 21B and 21C of the garnish 21 and the roof lining 6. The interior of the passenger compartment 2 is illuminated by the indirect light reflected and diffused by the roof lining 6.

Further, the light radiated from the light emitting members 22 and 23 and once reflected and diffused on the inner surface of the garnish 21 (the surface on the light radiating members 22 and 23 side) is also refining with the respective edges 21B and 21C of the garnish 21. 6 is radiated to the outside of the lighting devices 3 and 4 through a gap with the light source 6.
On the other hand, the direct light emitted from the light emitting member 22 to the room mirror 5 and the windshield 11 is shielded by the convex portion 6 </ b> A of the roof lining 6 and the front edge 21 </ b> B of the garnish 21. That is, here, the convex portion 6 </ b> A of the roof lining 6 and the edge of the garnish 21 function directly as a light suppression member.

Moreover, the direct light irradiated to each passenger | crew or living space from each illuminating device 3, 4 is interrupted | blocked by each garnish 21, and these direct lights are not irradiated with respect to a passenger | crew.
The direct light emitted from the other light radiating member 23 of the illuminating device 3 and each light radiating member (not shown) of the illuminating device 4 to the room mirror 5 and the windshield 11 is a special direct light suppressing member. There is no need to provide it, and it is shielded by garnish 21 or the like.

  Thus, according to the vehicle interior indirect lighting device of the present invention, the light emitting members 22 and 23 can emit light in a rod shape (linear shape) while using the LED 24A to 27A that are point light sources as light sources. By reflecting and diffusing the direct light radiated from the light emitting members 22 and 23 to the inside of the garnish 21 or the roof lining 6 or the like, indirect light having high diffusibility can be supplied to the vehicle interior 2. That is, indirect illumination with a line light source can be performed without arranging many point light sources in a line or using a line light source such as a fluorescent lamp.

  Moreover, since the light emitted from the notched surfaces 22A and 23A side of the light emitting members 22 and 23 is reflected by the reflecting members 30 and 31 and bent to the radiation surfaces 22B and 23B side, the light emitting member The light radiated from 22 and 23 can be radiated in the range of the radiation surfaces 22B and 23B. In addition, since the reflecting members 30 and 31 are oriented so as to face the gap between the edge portions 21B and 21C and the roof lining 6, most of the light emitted from the radiation surfaces 22B and 23B is garnish 21 or the like. Therefore, the roof lining 6 that is a reflecting surface for obtaining the indirect light without being shielded by the light is irradiated to the roof lining 6 and a large amount of light can be supplied to the roof lining 6 without waste. Thereby, the passenger compartment 2 can be sufficiently illuminated while suppressing the outputs (power consumption) of the LEDs 24A to 27A of the light source devices 24 to 27 as much as possible.

Further, the direct light applied to the room mirror 5 from the foremost light emitting members 22 and 23 is shielded or reduced by the garnish 21 and the convex portion 6A of the roof lining 6 so that it is emitted from the light emitting members 22 and 23. It is possible to prevent the driver from being dazzled by direct light reflected on the room mirror 5.
Further, the edge portions 21B and 21C of the garnish 21 and the convex portion 6A of the roof lining 6 are set to have a vehicle width direction length equal to or greater than the vehicle width direction length of the light emission members 22 and 23. The direct light emitted from the members 22 and 23 to the windshield 11 can be blocked or reduced, and the direct light emitted from the light emitting members 22 and 23 is reflected on the windshield 11 so that the driver is dazzled. Can be prevented.

  In addition, since an LED can be used as the light source, the light source is relatively inexpensive, has a long life, can achieve high output with low power consumption, and has a filament like a light bulb. There are advantages peculiar to LED light sources, such as a point resistant to vibration and a point that a maximum light amount can be obtained immediately after lighting.

Next, a modification of the present invention will be described with reference to FIG. In addition, about the thing which is not changed from embodiment in this modification, detailed description is abbreviate | omitted using a same sign.
As shown in FIG. 5, in this modified example, the length (height) of the front edge 41B of the garnish 41 of the lighting device 3 is set longer than that of the embodiment, and is convex to the roof lining 6 '. This is different from the above-described embodiment in that no part is provided.
By setting the length of the front edge 41 </ b> B of the garnish 41 to be large, the edge 41 </ b> B is positioned on the virtual line P connecting the upper end of the light emitting member 22 and the lower end of the room mirror 5. That is, the edge 41 </ b> B shields the direct light irradiated from the light emitting member 22 to the room mirror 5 and the windshield 11. That is, here, the edge portion 41B functions directly as a light suppressing member.

  Note that the edge portion 41B does not necessarily have to be configured to completely block the direct light applied to the room mirror 5, and at least a part of the direct light is shielded and applied to the room mirror 5. What is necessary is just to comprise so that direct light may be suppressed.

Thus, according to the vehicle interior indirect lighting device according to the modification of the present invention, it is possible to obtain the same effects as those of the above-described embodiment.
Further, since the length of the edge portion 41B of the garnish 41 is set to be large, the gap between the roof lining 6 and the edge portion 41B is narrowed, while the lighting devices 3 and 4 are not provided with a projection on the roof lining 6 '. Therefore, there is an advantage that the direct light applied to the room mirror 5 and the windshield 11 can be shielded or reduced.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
In the above-described embodiment, the convex portion 6A of the roof lining 6 and the edge portion 21B of the garnish 21 are used together to function as a direct light suppression member, but only one of them functions as a direct light suppression member. You may do it.
Moreover, you may make it function not only as the convex part 6A of the roof lining 6, but the edge part of the garnish 21, but other members directly as a light suppression member. For example, by appropriately setting the installation position of the reflecting member provided on the light emitting member, the direct light irradiated from the light emitting member to the room mirror is suppressed. You may comprise so that it may combine.

In addition, the direct light suppressing member does not necessarily need to shield all the direct light applied to the room mirror from the light emitting member, but can reduce the direct light applied to the room mirror and suppress the driver's dazzling. If it is.
In the above-described embodiment, acrylic resin is used as the light emitting member. However, the material of the light emitting member is not limited to acrylic resin as long as it has a light transmitting property. It may be formed. Further, the shape of the light radiating member is not limited to a linear shape, and the light radiating member may be configured in a curved shape so as to change the direction and amount of light emitted from the light radiating member. Good.

Further, the light source is not limited to the LED, and a normal light bulb or a halogen light bulb may be used instead of the LED. By using a light bulb as the light source, the color rendering property of the indirect lighting device for the passenger compartment can be improved as compared with the case of using other light sources.
On the other hand, it is preferable to set a light source having appropriate directivity in order to make light incident on the light emitting member efficiently. Or you may comprise so that the directivity of the light from a light source may be improved by providing a light-condensing plate etc. in the light source device incorporating a light source.

  Further, in the above-described embodiment, the direct light emitted from the light emitting member is mainly applied to the roof lining which is the upper surface of the interior of the vehicle interior. The trim or lining forming the side surface of the vehicle interior is not limited. In addition, a new member for reflecting and diffusing the direct light emitted from the light radiating member is provided to increase the uniformity of the illumination light, or on the contrary, to change the illumination by making the illumination light non-uniform. You may comprise.
