Japanese Patent Application Publication No. 2005-193804

However, the indoor lighting device of Patent Document 1 includes a direct illumination lamp body separately from an indirect illumination lamp body. Therefore, it is necessary to separately provide a lamp support base for the direct illumination lamp and a lamp support base for the indirect illumination lamp, which increases the number of lamp support bases. Therefore, the number of parts required to provide the direct illumination lamp body and the indirect illumination lamp body increases, and the number of assembly steps also increases. In addition, the increased number of parts may increase the weight of the vehicle.

The present invention can support two types of lighting lamps, direct lighting lamps and indirect lighting lamps, while suppressing an increase in the number of parts, and further allows the driver, other passengers, and surrounding vehicles to recognize the vehicle status. The purpose of the present invention is to provide an interior lighting device for a vehicle that can be effectively used for purposes such as lighting.

In order to solve the above problems, the present invention proposes the following means.
(1) The indoor lighting device for a vehicle according to the present invention includes a lamp support base (for example, the lamp support base 13 of the embodiment) provided in a vehicle (for example, the vehicle 1 of the embodiment), and a lamp support base (for example, the lamp support base 13 of the embodiment). A direct illumination light body (for example, the direct illumination light body 22 of the embodiment) that is supported by a base and irradiates direct light into the vehicle interior, and a direct illumination light body that is supported by the light body support base and irradiates reflected light into the vehicle interior. An indirect illumination light body (for example, the indirect illumination light body 24 of the embodiment), a vehicle state determination section that determines the state of the vehicle (for example, the vehicle state determination section 16 of the embodiment), and a direct illumination light body that lights up the light body. an indirect lighting mode in which the indirect lighting lamp is turned on; an all-lamp lighting mode in which the direct lighting lamp and the indirect lighting lamp are turned on; and at least one of the direct lighting lamp and the indirect lighting lamp. a lighting control section (e.g., the lighting control section 17 of the embodiment) that selects a mode from among the flashing lighting modes that cause the vehicle to blink, and switches to the selected mode; The mode is switched to the selected mode according to the determined state of the vehicle.

According to this configuration, two types of illumination lamp bodies, a direct illumination lamp body and an indirect illumination lamp body, can be supported by the same lamp support base. Thereby, it is possible to support two types of illumination lamp bodies, the direct illumination lamp body and the indirect illumination lamp body, while suppressing an increase in the number of parts, and it is possible to reduce the weight of the vehicle.

In addition, depending on the vehicle condition, the irradiation of the direct illumination light body and the indirect illumination light body (i.e. vehicle interior light) is selected from among direct illumination mode, indirect illumination mode, all-light illumination mode, and flashing illumination mode. mode can be switched. Thereby, the driver can recognize the state of the vehicle based on the irradiation state of the direct illumination lamp body and the indirect illumination lamp body, and can effectively utilize the interior lighting device.

Further, occupants other than the driver can also recognize the state of the vehicle based on the illumination state of the direct illumination lamps and the indirect illumination lamps. As a result, occupants other than the driver can also recognize the state of the vehicle, which was conventionally known only to the driver, from the illumination states of the direct illumination lamps and the indirect illumination lamps.
In other words, with this configuration, it is possible to support two types of lighting lamps, direct lighting lamps and indirect lighting lamps, while suppressing an increase in the number of parts, and further protect the driver, other passengers, and surrounding vehicles. It can be effectively used to make people aware of the vehicle status.

(2) In the above aspect, the lighting control unit includes a first adjustment unit (for example, a first adjustment unit in the embodiment) that adjusts the illuminance of the irradiation light emitted from at least one of the direct lighting lamp body and the indirect lighting lamp body. means 45), and a second adjustment means (for example, second adjustment means 46 of the embodiment) for adjusting the emission color of the irradiation light emitted from at least one of the direct illumination lamp body and the indirect illumination lamp body. The illumination control unit may adjust the illuminance by controlling the first adjustment means and adjust the emission color by controlling the second adjustment means according to the state of the vehicle. .

According to this configuration, the illuminance emitted from at least one of the direct illumination lamp body and the indirect illumination lamp body can be adjusted by the first adjustment means according to the state of the vehicle. Therefore, for example, while the vehicle is running manually or automatically, the illuminance of the irradiation light emitted from at least one of the direct illumination lamp and the indirect illumination lamp can be lowered. This makes it possible to suppress the brightness (darkness) in the vehicle interior to a level suitable for driving the vehicle. Therefore, while the vehicle is running, it is possible to prevent the irradiation from the direct illumination lamp body and the indirect illumination lamp body from affecting the running of the vehicle, and furthermore, it is possible to improve the quality of the interior of the vehicle cabin provided to the occupants.

Here, for example, the occupant is relaxed while the vehicle is running automatically. Therefore, depending on the state of the vehicle, the color of the emitted light emitted from at least one of the direct illumination lamp and the indirect illumination lamp is changed to a soft color such as green, for example, by the second adjustment means. This makes it possible to further enhance the sense of relaxation for the occupants, and further improve the quality of the interior of the vehicle provided to the occupants.

(3) In the above aspect, a vehicle interior light (for example, the vehicle interior light 15 of the embodiment) having the direct illumination light body and the indirect illumination light body is provided, and the vehicle interior light is provided in the vehicle interior. The vehicle state determining section is arranged on the outer side in the vehicle width direction of a facing ceiling member (for example, the roof lining 11 of the embodiment), and the vehicle state determining section is a turn signal determining section (for example, , the turn signal determining section 41) of the embodiment, and the lighting control section may switch the vehicle interior light to the selected mode based on the lighting state of the turn signal determined by the turn signal determining section.

According to this configuration, the vehicle interior light is arranged on the outer sides in the vehicle width direction with respect to the ceiling member (that is, on the left and right roof sides). Further, the vehicle state determining section includes a turn signal determining section, and the turn signal determining section can determine the lighting state of the turn signal. Therefore, based on the lighting state of the turn signal determined by the turn signal determination section, the vehicle interior lights disposed on the left and right roof sides can be controlled by the illumination control section.
Thereby, for example, when the vehicle turns right or left, the lighting control unit 17 can switch to a blinking lighting mode in which the vehicle interior light on the side corresponding to the right turn or left turn blinks. Therefore, occupants other than the driver can also visually recognize the direction in which the vehicle is turning based on the blinking state of the vehicle interior light.

(4) In the above aspect, a vehicle interior light (for example, the vehicle interior light 15 of the embodiment) having the direct illumination light body and the indirect illumination light body is provided, and the vehicle state determination unit is configured to The lighting control section includes a shift determination section (for example, the shift determination section 42 of the embodiment) that determines a shift state of a shift lever section provided with the vehicle, and the illumination control section The interior light may be switched to the selected mode.

According to this configuration, the vehicle state determining section includes the shift determining section, and the shift determining section can determine the shift state when switching the shift state of the shift lever section. Therefore, the vehicle interior light can be switched to the mode selected by the lighting control section based on the shift state determined by the shift determination section. Thereby, the driver can visually recognize the position of the shift lever (that is, the shift state) using the vehicle interior light.
Furthermore, occupants other than the driver can also visually recognize the shift state of the shift lever using the vehicle interior light. In addition, vehicles located around the vehicle other than at the rear can visually recognize the shift state of the shift lever using the vehicle interior light.

(5) In the above aspect, a vehicle interior light (for example, the vehicle interior light 15 of the embodiment) having the direct illumination light body and the indirect illumination light body is provided, and the vehicle state determination unit is configured to The illumination control unit includes a power source determination unit (for example, the power source determination unit 43 of the embodiment) that determines the state of the power source, and the lighting control unit determines the state of the power source determined by the power source determination unit. , the vehicle interior light may be switched to the selected mode.

Here, some recent vehicles are known to use electricity to start the power source when starting or stopping the power source. In the case of this vehicle, the volume in the starting state is suppressed to be lower than that of a vehicle equipped with an internal combustion engine. Therefore, it is difficult for the occupant to recognize whether the power source is started or stopped.
Therefore, in this configuration, the vehicle state determining section includes a power source determining section, and the power source determining section determines the state of the power source. Based on the power source state determined by the power source determination section, the vehicle interior light can be switched to the mode selected by the illumination control section. As a result, the occupant can visually recognize whether the power source is started or stopped using the vehicle interior light.

According to the present invention, it is possible to support two types of lighting lamps, direct lighting lamps and indirect lighting lamps, while suppressing an increase in the number of parts. It can be effectively used to make people recognize.

As shown in FIG. 4, in the indirect illumination mode, the indirect illumination lamp 24 is turned on and lit, and the direct illumination lamp 22 is turned off and turned off. The indirect lighting mode is applied, for example, when the vehicle 1 is driving.

FIG. 5 is a cross-sectional view illustrating the all-lamp illumination mode switched by the illumination control unit 17. As shown in FIG. 5, in the full-light illumination mode, the direct illumination light body 22 and the indirect illumination light body 24 are each turned on and turned on.
FIG. 6 is a cross-sectional view illustrating the blinking lighting mode switched by the lighting control unit 17. As shown in FIG. 6, in the blinking lighting mode, at least one of the direct lighting lamp 22 and the indirect lighting lamp 24 is controlled to blink. That is, the blinking lighting mode can be selected from three modes: blinking both the direct illumination lamp 22 and the indirect illumination lamp 24, blinking only the direct illumination lamp 22, and blinking only the indirect illumination lamp 24.
In FIG. 6, a state in which both the direct illumination lamp body 22 and the indirect illumination lamp body 24 are blinked is shown. Hereinafter, as a representative example of the blinking lighting mode, a case will be described in which both the direct lighting lamp 22 and the indirect lighting lamp 24 are made to blink.

Here, the lighting control unit 17 selects one of the direct lighting mode, indirect lighting mode, full-light lighting mode, and blinking lighting mode according to (based on) the state of the vehicle 1 transmitted from the vehicle state determination unit 16. mode and switch to the selected mode. Therefore, lighting and blinking of the direct illumination light body 22 and the indirect illumination light body 24 are controlled by the vehicle state determination section 16 and the illumination control section 17 according to the state of the vehicle 1.
Hereinafter, the "direct lighting mode, indirect lighting mode, full-light lighting mode, and blinking lighting mode" may be collectively abbreviated as "various lighting modes."

Next, a specific example of controlling lighting and blinking of the vehicle interior light 15 according to the state of the vehicle 1 by the vehicle state determination section 16 and the illumination control section 17 will be described based on FIGS. 7 to 16.
FIG. 7 is a cross-sectional view illustrating an example in which the vehicle interior light 15 on the left side in the vehicle width direction is controlled to the indirect lighting mode in accordance with the lighting state of the turn signal. FIG. 8 is a cross-sectional view illustrating an example in which the vehicle interior light 15 on the right side in the vehicle width direction is controlled to the blinking lighting mode in accordance with the lighting state of the blinker.

As shown in FIGS. 7 and 8, for example, the lighting control unit 17 controls various vehicle interior lights 15 based on the lighting state of the blinker determined by the blinker determination unit 41 (see FIG. 2) when the vehicle 1 is driving. Switch to the selected lighting mode.
Specifically, when making a right turn while driving the vehicle 1, the turn signal determination section 41 (see FIG. 2 for both) of the vehicle state determination section 16 determines the lighting state of the right turn signal in the vehicle width direction. Turn signal lighting information determined by the blinker determination section 41 is transmitted from the vehicle state determination section 16 to the lighting control section 17 . The lighting control unit 17 switches the vehicle interior light 15 on the left side in the vehicle width direction to indirect lighting mode based on the turn signal lighting information transmitted from the vehicle state determination unit 16, and switches the vehicle interior light 15 on the right side in the vehicle width direction to indirect lighting mode. Switch to flashing lighting mode.

The vehicle interior light 15 on the left side in the vehicle width direction is maintained in the indirect illumination mode, so that the indirect illumination light body 24 is kept on and the direct illumination light body 22 is kept off. On the other hand, the vehicle interior light 15 on the right side in the vehicle width direction is switched to the blinking lighting mode, so that the direct illumination light body 22 and the indirect illumination light body 24 blink. Therefore, the occupant can confirm that the vehicle 1 is turning right.

Furthermore, when turning left while driving the vehicle 1, the vehicle interior light 15 on the right side in the vehicle width direction is kept in the indirect illumination mode, so that the indirect illumination light body 24 on the right side in the vehicle width direction is turned on, and the indirect illumination light body 24 on the right side in the vehicle width direction is lit. The illumination lamp body 22 is kept in an extinguished state. On the other hand, by switching the vehicle interior light 15 on the left side in the vehicle width direction to the blinking lighting mode, the direct illumination light body 22 and the indirect illumination light body 24 on the left side in the vehicle width direction each blink.

FIG. 9 is a cross-sectional view illustrating an example in which the vehicle interior light 15 is controlled to the all-light illumination mode according to the shift state of the shift lever section.

FIG. 11 is a sectional view illustrating an example in which the vehicle interior light 15 is controlled to the direct illumination mode according to the shift state of the shift lever section. FIG. 12 is a cross-sectional view illustrating an example of controlling the vehicle interior light 15 to a blinking lighting mode according to the shift state of the shift lever section.

As shown in FIGS. 9 to 12, the lighting control section 17 controls the vehicle interior light 15 based on the shift state of the shift lever section determined by the shift determination section 42 (see FIG. 2) during operation of the vehicle 1, for example. Switch to the selected mode from among various lighting modes.

As described above, according to the vehicle interior lighting device 10 of the embodiment, as shown in FIGS. Different lighting lamp bodies can be supported by the same lamp support base 13. Thereby, two types of illumination lamp bodies, the direct illumination lamp body 22 and the indirect illumination lamp body 24, can be supported while suppressing an increase in the number of parts, and the weight of the vehicle can be reduced.

In addition, depending on the state of the vehicle 1, the irradiation of the direct illumination light body 22 and the indirect illumination light body 24 (that is, the vehicle interior light 15) is controlled in direct illumination mode, indirect illumination mode, all-light illumination mode, and flashing illumination mode. You can switch to the mode of your choice. Thereby, the driver can recognize the state of the vehicle 1 based on the illumination state of the direct illumination lamp 22 and the indirect illumination lamp 24, and can effectively utilize the interior lighting device 10.
Further, occupants other than the driver can also recognize the state of the vehicle 1 based on the illumination state of the direct illumination lamp 22 and the indirect illumination lamp 24. Thereby, occupants other than the driver can also recognize the state of the vehicle 1, which was conventionally known only to the driver, by the illumination states of the direct illumination lamp 22 and the indirect illumination lamp 24.
That is, according to the vehicle interior lighting device 10, two types of lighting bodies, the direct lighting body 22 and the indirect lighting body 24, can be supported while suppressing an increase in the number of parts. It can also be effectively used to make surrounding vehicles aware of the state of the vehicle 1.

Furthermore, the illuminance emitted from the direct illumination lamp body 22 and the indirect illumination lamp body 24 can be adjusted by the first adjustment means 45 according to the state of the vehicle 1. Therefore, for example, while the vehicle 1 is running in manual operation or automatic operation, the irradiation light emitted from at least one of the direct illumination light body 22 and the indirect illumination light body 24 (the indirect illumination light body 24 is exemplified in the embodiment). The illuminance can be lowered. Thereby, the brightness (darkness) in the vehicle interior can be suppressed to a level suitable for driving the vehicle 1. Therefore, while the vehicle 1 is running, it is possible to prevent the irradiation from the indirect illumination lamp 24 from affecting the running of the vehicle 1, and furthermore, it is possible to improve the quality of the interior of the vehicle cabin given to the occupants.

Here, for example, while the vehicle 1 is running automatically, the occupant is relaxed. Therefore, depending on the state of the vehicle 1, the second adjustment means 46 adjusts the color of emitted light emitted from at least one of the direct illumination lamp 22 and the indirect illumination lamp 24 (the indirect illumination lamp 24 is exemplified in the embodiment), for example. Change to a soft color such as green. This makes it possible to further enhance the sense of relaxation for the occupants, and further improve the quality of the interior of the vehicle provided to the occupants.

Furthermore, vehicle interior lights 15 are arranged on the outer sides in the vehicle width direction with respect to the roof lining 11 (that is, on the left and right roof sides). Further, the vehicle state determining section 16 includes a turn signal determining section 41, and the turn signal determining section 41 can determine the lighting state of the turn signal. Therefore, based on the lighting state of the turn signal determined by the turn signal determination section 41, the lighting control section 17 can control the vehicle interior lights 15 disposed on the left and right roof sides.

Thereby, for example, when the vehicle 1 turns right or left, the lighting control unit 17 causes the direct illumination light body 22 and the indirect illumination light body 24 of the vehicle interior light 15 on the side corresponding to the right turn or left turn to blink. Can be switched to lighting mode. Therefore, occupants other than the driver can also visually recognize the direction in which the vehicle 1 is turning based on the blinking state of the vehicle interior light 15.

In addition, the vehicle state determining section 16 includes a shift determining section 42, and the shift determining section 42 can determine the shift state when switching the shift state of the shift lever section. Therefore, based on the shift state determined by the shift determination section 42, the vehicle interior light 15 can be switched to a mode selected from among various illumination modes by the illumination control section 17. Thereby, the driver can visually recognize the position of the shift lever (that is, the shift state) using the vehicle interior light 15.
Furthermore, occupants other than the driver can also visually recognize the shift state of the shift lever using the vehicle interior light 15. In addition, vehicles located around the vehicle 1 other than behind the vehicle 1 can also visually recognize the shift state of the shift lever using the vehicle interior light 15.

Here, some recent vehicles 1 are known that use electricity to start the power source when starting or stopping the power source. In the case of this vehicle 1, the sound volume in the starting state is suppressed to be lower than that of a vehicle 1 equipped with an internal combustion engine. Therefore, it is difficult for the occupant to recognize whether the power source is started or stopped.

Therefore, the vehicle state determining section 16 is provided with a power source determining section 43, and the power source determining section 43 determines the state of the power source. Based on the power source state determined by the power source determining section 43, the vehicle interior light 15 can be switched to a mode selected from various illumination modes by the illumination control section 17. Thereby, the occupant can visually recognize whether the power source is activated or stopped using the vehicle interior light 15.
