Description
Technical Field
The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp including a display for displaying information and a marker lamp.
Background
There is known a vehicle having a display unit that displays a message of a state of the vehicle or the like to the outside. As the display device, a display device such as a liquid crystal display device may be used. It is also known that such a display device is provided on a rear surface of a vehicle and is arranged in parallel with a marker lamp such as a rear combination headlight.
Patent document 1: japanese Kokai publication No. 2007-531904
Disclosure of Invention
When the display device is provided outside the vehicle, a person outside the vehicle, such as a pedestrian or an occupant of another vehicle, tends to look at the image of the display device. However, in the display device described in patent document 1, since the display device and the marker lamp are spaced from each other as described above, there is a fear that a person outside the vehicle who looks at the image of the display device needs to notice a change in the marker lamp. The change of the indicator light indicates an emergency as in the case of turning on the brake light, and requires attention from a person outside the vehicle as soon as possible.
Accordingly, the present invention is intended to provide a vehicle lamp excellent in attention calling performance.
In order to achieve the above object, a vehicle lamp according to the present invention includes: a light-emitting panel divided into a plurality of regions, each of the regions being independently lighted; a light transmissive display; a predetermined region of the light emitting panel is overlapped with the light-transmitting display and is used as a backlight of the light-transmitting display, and another region of the light emitting panel is exposed from the light-transmitting display and is used as a marker lamp.
In such a vehicle lamp, a display for displaying an image is adjacent to a marker lamp by using a backlight of a light-transmitting display as a predetermined region of a light-emitting panel. Therefore, compared to the case where the indicator and the marker lamp are provided separately at a predetermined interval, the time until the indicator lamp changes is noticed by a person outside the vehicle who looks at the image of the indicator can be shortened. Therefore, with the vehicle lamp of the present invention, attention calling performance can be optimized.
Further, since the light-emitting panel is divided into a region for the backlight of the light-transmissive display and a region for the marker light to be used, the lighting drive circuit and the like can be shared, and the vehicle lamp can be manufactured at a lower cost than a case where the backlight of the light-transmissive display and the marker light are separately provided.
Preferably, at least a part of the other region of the light-emitting panel is a stop lamp region that is turned on when the vehicle brakes, and the brightness of light emitted from the stop lamp region is set to be higher than the brightness of light emitted from the transmissive display.
In such a vehicle lamp, the brake lamp is made brighter than the display, and therefore, the attention of the brake lamp can be increased, and therefore, the vehicle lamp has higher attention calling performance.
In this case, it is preferable that the light-emitting panel reduces the brightness of light emitted from the predetermined region when the vehicle performs the braking operation.
The display is darkened by reducing the brightness of light from a predetermined region that becomes a backlight of the light-transmitting display during a braking operation. Therefore, the person outside the vehicle feels the light from the brake lamp area relatively brighter and is liable to look at the brake lamp. Therefore, with such a configuration, higher attention calling performance can be achieved.
In addition, it is preferable that, in a state where at least a part of the marker lamp is turned on, a luminance of light emitted from a region adjacent to the turned-on portion of the marker lamp out of the predetermined region is set to be higher than a luminance of light emitted from a region opposite to the turned-on portion of the marker lamp out of the predetermined region.
A person who visually recognizes the display tends to feel relatively darker in an area of the display adjacent to the light-emitting member that is brightly lit than in an area adjacent to a member that is not particularly lit. However, by causing a predetermined region constituting the backlight of the transmissive display to emit light as described above, a region adjacent to the marker lamp of the display, which is likely to be perceived as dark by a person as described above, is brightened, and the display can be visually confirmed with good balance as a whole.
The light emitting panel may be an organic EL panel or an LED array panel.
In addition, the transmissive display may be a liquid crystal display.
Effects of the invention
As described above, according to the present invention, a vehicle lamp excellent in attention calling performance can be provided.

Detailed Description
Hereinafter, a mode for implementing the vehicle lamp of the present invention is exemplified together with the drawings. The following illustrative embodiments are provided to facilitate understanding of the present invention and are not intended to be construed as limiting the invention. The present invention can be modified and improved according to the following embodiments without departing from the gist thereof.
Fig. 1 is a diagram showing an example of a vehicle in which the vehicle lamp according to the present embodiment is mounted. Fig. 1 is a view of a vehicle VE as viewed from the rear side, and the vehicle VE of the present embodiment includes a vehicle lamp 1, as shown in fig. 1. The vehicle lamp 1 of the present embodiment includes a marker lamp 2 and a display 5. Since the vehicle lamp 1 of the present embodiment includes the marker lamp 2, the vehicle lamp 1 is provided one on each of the rear surfaces of the vehicle VE in the left-right direction. Each of the vehicle lamps 1 is exposed to the outside of the vehicle VE, and emits light from the marker lamp 2 and the display 5 to the outside of the vehicle VE. Therefore, the display 5 is a light-emitting display.
Fig. 2 is an exploded view of the vehicle lamp 1 in the present embodiment. As shown in fig. 2, the vehicle lamp 1 of the present embodiment includes a light-emitting panel 20, a transmissive display 50, and a control unit 3 as main components.
The light-emitting panel 20 is an organic EL panel in the present embodiment, and each of the regions divided into a plurality of regions is independently lit. Specifically, the light-emitting panel 20 is divided into a backlight region 25, a stop lamp region 21, a turn lamp region 22, and a backup lamp region 23. Here, when the backlight region 25 is a predetermined region of the light-emitting panel 20, the stop lamp region 21, the turn lamp region 22, and the back-up lamp region 23 are set as other regions of the light-emitting panel 20, and the marker lamp 2 is configured in the other regions. Accordingly, the stop lamp area 21 is lit red, the turn lamp area 22 is lit orange, and the backup lamp area 23 is lit white. In the present embodiment, the backlight area 25 is lit to white. The light-emitting panel 20 includes a drive circuit for lighting, not shown, which receives a signal from the control unit 3 and sets each region to be independently in a lighting state or a non-lighting state.
The transmissive display 50 is a display for emitting light incident from the rear surface from the front surface, and is formed of, for example, a liquid crystal display. The light-transmitting display 50 has a rectangular outer diameter and has a plurality of pixels arranged in a matrix within the rectangle. Each pixel includes a red display dot that transmits red light, a green display dot that transmits green light, and a blue display dot that transmits blue light. Therefore, in the present embodiment, the transmissive display 50 can perform RGB color display. Further, a scanning line driving circuit 50H is disposed on the lateral side of the transmissive display 50, and a data line driving circuit 50V is disposed on the vertical side of the transmissive display 50. The scanning line driving circuit 50H and the data line driving circuit 50V are electrically connected to the display dots of the pixels, and the scanning line driving circuit 50H and the data line driving circuit 50V apply voltages to the display dots, thereby controlling the transmission and non-transmission states of light and the amount of light transmitted by the display dots of RGB.
The light-transmissive display 50 and the backlight region 25 of the light-emitting panel 20 are overlapped with each other so that the light-emitting panel 20 is located on the rear surface of the light-transmissive display 50, and the backlight region 25 is used as a backlight of the light-transmissive display 50. Therefore, the light emitted from the backlight region 25 passes through each display dot of the transmissive display 50, and is emitted from the front surface of the transmissive display 50. As described above, since the backlight region 25 is lit to be white, the light emitted from the backlight region 25 includes red light, green light, and blue light. The display dots in which the transmission amount of the light transmission light is controlled display a color image on the transmissive display 50. Therefore, in the present embodiment, the light-emitting display 5 is provided in the backlight region 25 of the light-transmitting display 50 and the light-emitting panel 20.
In the present embodiment, 2 sides of the rectangular transmissive display 50 adjacent to each other are adjacent to the marker lamp 2, and the stop lamp region 21, the turn lamp region 22, and the backup lamp region 23 are adjacent to the transmissive display 50.
The control section 3 is electrically connected to the scanning line driving circuit 50H and the data line driving circuit 50V, and controls the transmission and non-transmission states of light of the pixels of the transmissive display 50. The control unit 3 performs this control based on a signal input from the outside to the control unit 3. In the present embodiment, the Control unit 3 is electrically connected to a Control device 6 such as an ecu (engine Control unit) of the vehicle VE, an image display instruction unit 7, and the like. The control device 6 of the vehicle VE monitors at least the braking operation, and outputs a signal indicating the braking operation when the braking operation is performed. The image display instruction unit 7 outputs a signal for displaying a predetermined image on the display 5. The signal contains information relating to the content of the image. The predetermined image is not particularly limited. Therefore, the predetermined image may be a still image, a moving image, or a predetermined character or the like. Fig. 2 shows a case where an image indicating "AUTO drive" is displayed on the display 5 for display.
Next, the operation of the vehicle lamp 1 of the present embodiment will be described. Fig. 3 is a diagram showing a control flowchart of the control unit 3. In step SP1, the control unit 3 detects the image signal from the image display instructing unit 7, and when an image signal for displaying a predetermined image is input from the image display instructing unit 7, the processing proceeds to step SP 2.
In step SP2, the control unit 3 controls the light-transmissive display 50 and the light-emitting panel 20 so that a predetermined image is displayed on the display 5. Specifically, the control unit 3 controls the light-emitting panel 20 to light the backlight region 25. In this case, it is preferable to turn on the backlight region 25 so that light having uniform brightness is emitted from the entire backlight region 25. Further, the control section 3 drives the scanning line driving circuit 50H and the data line driving circuit 50V based on information about the content of the image included in the image signal from the image display instructing section 7. The scanning line driving circuit 50H and the data line driving circuit 50V adjust the applied voltages, and adjust the states of light transmission through the red display dots, the green display dots, and the blue display dots of the pixels of the light-transmitting display 50. In this way, the control unit 3 controls the respective pixels, and the light emitted from the backlight region 25 of the light-emitting panel 20 passes through the light-transmissive display 50 to form a predetermined image, thereby displaying the predetermined image on the display 5.
On the other hand, in step SP1, when the image signal for displaying the predetermined image is not input from the image display instructing unit 7, the control unit 3 proceeds to step SP 3.
In step SP3, the control unit 3 controls not to display an image on the display monitor 5. Specifically, the control unit 3 controls the light-emitting panel 20 so that the backlight region 25 is not lit. Further, the control section 3 drives the scanning line driving circuit 50H and the data line driving circuit 50V to control the pixels so that light does not pass through each point of the pixels of the light-transmissive display 50. In this way, light is not emitted from the display monitor 5, and an image is not particularly displayed.
The control unit 3 controls each pixel so that a predetermined image is displayed on the display 5 in step SP2, and thereafter, proceeds to step SP4, and controls each pixel so that the display 5 does not display an image in step SP3, and thereafter, proceeds to step SP 4.
At step SP4, the control unit 3 detects a signal indicating a braking operation from the control device 6, and proceeds to step SP5 when the signal indicating the braking operation is input to the input state of the control unit 3. In step SP5, the control unit 3 controls the light-emitting panel 20 to light the stop lamp region 21. Thus, the brake light area 21 of the identification light 2 is illuminated in red.
When the process proceeds to step SP5 via step SP2, in the present embodiment, the luminance of the light emitted from the display 5, that is, the light emitted from the transmissive display 50 after passing through the transmissive display 50 is set to be lower than the luminance of the light emitted from the stop lamp region 21. When the brightness of the light emitted from the display 5 does not change before and after the braking operation, in step SP5, the control unit 3 turns on the stop lamp region 21 so that the brightness of the light emitted from the stop lamp region 21 becomes higher than the brightness of the light emitted from the transmissive display 50.
In step SP5, the control unit 3 preferably decreases the luminance of the light emitted from the display 5. Specifically, in step SP5, the control unit 3 controls the light-emitting panel 20 to reduce the brightness of the light emitted from the backlight region 25. Since the light emitted from the display 5 is the light emitted from the backlight region 25, transmitted through the light-transmissive display 50, and emitted from the light-transmissive display 50, the luminance of the light emitted from the display 5 is reduced by reducing the luminance of the light emitted from the backlight region 25. In other words, the display 5 becomes dark. Therefore, the person outside the vehicle feels that the light from the stop lamp area 21 is relatively bright, and thus the person can easily watch the stop lamp. In this way, the brightness of the light emitted from the backlight region 25 is controlled during the braking operation, and the vehicle lamp 1 can have a high attention calling performance.
In step SP5, the control unit 3 may control each pixel of the transmissive display 50 so that red light is emitted from the display 5. When the process proceeds to step SP5 via step SP2, the backlight region 25 is turned on in step SP2, and therefore the control unit 3 may not adjust the luminance of the light emitted from the backlight region 25. Alternatively, the control unit 3 may control the light-emitting panel 20 so that the brightness of the light emitted from the stop lamp region 21 and the brightness of the light emitted from the display 5 are substantially the same, and may adjust the brightness of the light emitted from the backlight region 25. By emitting red light from the display 5 during a braking operation, the display 5 has a function equivalent to that of a brake light except for the brake light region 21, and the vehicle lamp 1 can have a higher attention calling performance.
When the process proceeds to step SP5 via step SP3, the control unit 3 keeps the backlight region 25 of the light-emitting panel 20 unlit. In this case, the display 5 does not display any image before and after the braking operation. Alternatively, when the process proceeds to step SP5 via step SP3, the control unit 3 may control the light-emitting panel 20 and the transmissive display 50 so that red light is emitted from the display 5 in step SP 5. Specifically, in step SP5, the control unit 3 turns on the backlight region 25 of the light-emitting panel 20 and controls each pixel of the light-transmissive display 50 so that red light passes through the light-transmissive display 50. In this case, the display 5 has the same function as the brake lamp except for the brake lamp area 21, so that the vehicle lamp 1 can have higher attention calling performance.
Further, the control unit 3 blinks the turn signal region 22 of the light panel 20 when a signal relating to a turning operation is input from the control device 6, and lights the backup signal region 23 of the light panel 20 when a signal relating to a reversing operation is input from the control device 6.
As described above, the vehicle lamp 1 according to the present embodiment includes the light-emitting panel 20 and the transmissive display 50 which are divided into a plurality of regions and each of which is independently lit. A predetermined region of the light-emitting panel 20 overlaps the light-transmissive display 50 and serves as a backlight of the light-transmissive display 50. In addition, the other region of the light emitting panel 20 is exposed from the transmissive display 50 and is set as the marker lamp 2.
In the vehicle lamp 1, the display 5 for displaying an image is adjacent to the marker lamp 2 by using a predetermined region of the light-emitting panel 20 as a backlight of the light-transmitting display 50. Therefore, compared to the case where the display monitor and the marker lamp are provided at a predetermined interval, the time required for a person outside the vehicle to watch the image of the display monitor 5 to notice a change in the marker lamp 2 can be shortened, and the attention calling performance can be improved.
Further, since the light-emitting panel 20 is used in a state of being divided into the backlight region 25 of the light-transmissive display 50 and the region for the marker lamp 2, a driver for lighting and the like can be shared, and a vehicle lamp can be manufactured at a lower cost than a case where the backlight of the light-transmissive display 50 is provided separately from the marker lamp.
(second embodiment)
Next, a second embodiment of the present invention will be described in detail with reference to fig. 4. Note that the same or equivalent components as those in the first embodiment are denoted by the same reference numerals and redundant description thereof is omitted unless otherwise specified.
Fig. 4 is a view showing the vehicle lamp 1 according to the present embodiment in the same state as fig. 2. As shown in fig. 4, the vehicle lamp 1 of the present embodiment is different from the vehicle lamp 1 of the first embodiment in that the light-emitting panel 20 is a dot matrix panel. As such a light emitting panel 20, an LED array panel can be cited. The following description is made on the assumption that the light-emitting panel 20 is an LED array panel. LEDs emitting white light are arranged in a matrix in the backlight area 25, LEDs emitting red light are arranged in a matrix in the stop lamp area 21, LEDs emitting orange light are arranged in a matrix in the turn lamp area 22, and LEDs emitting white light are arranged in a matrix in the backup lamp area 23. In the present embodiment, a lighting drive circuit provided in the light-emitting panel 20 is illustrated. Specifically, the scanning line driving circuit 20H is disposed on the lateral side of the light-emitting panel 20, and the data line driving circuit 20V is disposed on the vertical side of the light-emitting panel 20. The scanning line drive circuit 20H and the data line drive circuit 20V are electrically connected to the LEDs, and by applying a current from the scanning line drive circuit 20H and the data line drive circuit 20V to the LEDs, the lighting and non-lighting states of the LEDs of the light-emitting panel 20 and the amount of light emitted during lighting are controlled.
In the present embodiment, as in the first embodiment, the light emission panel 20 is independently lit in each region to emit light.
In the present embodiment, in a state where at least a part of the marker lamp 2 is turned on, the luminance of light emitted from a region adjacent to the turned-on portion of the marker lamp 2 in the backlight region 25 which is a predetermined region is set to be higher than the luminance of light emitted from a region opposite to the turned-on portion of the marker lamp 2 in the backlight region 25. For example, as shown in fig. 3, when the process proceeds to step SP5 via step SP2, the control unit 3 causes the brake lamp area 21 of the indicator lamp 2 to emit red light in step SP 5. At this time, the scanning line drive circuit 20H and the data line drive circuit 20V are driven so that the region adjacent to the brake lamp region 21 in the backlight region 25 is brighter than the region on the opposite side of the brake lamp region 21 in the backlight region 25. In other words, in fig. 4, the upper region is brighter than the lower region in the backlight region 25. For example, when the vehicle VE performs a reverse operation, a signal related to the reverse operation is input from the control device 6 to the control unit 3, and the reverse lamp region 23 of the light-emitting panel 20 is turned on. At this time, the scanning line drive circuit 20H and the data line drive circuit 20V are driven so that the region adjacent to the backup lamp region 23 in the backlight region 25 is brighter than the region on the opposite side of the backup lamp region 23 in the backlight region 25. In other words, in fig. 4, the right region is brighter than the left region in the backlight region 25.
Generally, a person who visually recognizes a display tends to feel relatively darker in a region of the display adjacent to a light-emitting member that is brightly lit than in a region adjacent to a member that is not particularly lit. Therefore, by lighting the backlight region 25 of the transmissive display 50 as described above, the region adjacent to the marker lamp of the display, which is likely to be perceived as dark by a person, is lit, and the display 5 can be visually confirmed as a whole with good balance.
The present invention has been described above by taking the embodiments as examples, but the present invention is not limited to these embodiments.
For example, in the embodiment, the marker lamp 2 includes a brake lamp area 21, a turn lamp area 22, and a backup lamp area 23. However, the marker lamp 2 may include at least one of the stop lamp region 21, the turn lamp region 22, and the backup lamp region 23.
In the above embodiment, the transmissive display 50 is formed in a rectangular shape, but the shape of the transmissive display 50 can be changed as appropriate. In the above embodiment, the transmissive display 50 has a rectangular shape, and 2 sides of the transmissive display 50 adjacent to each other are provided adjacent to the marker lamp 2, but in the case where the transmissive display 50 has a rectangular shape, only one side of the transmissive display 50 may be provided adjacent to the marker lamp 2.
In the above embodiment, the stop lamp region 21, the turn lamp region 22, and the backup lamp region 23 are adjacent to the transmissive display 50, but the transmissive display 50 may be adjacent to at least one of the stop lamp region 21, the turn lamp region 22, and the backup lamp region 23.
Even when the light-emitting panel 20 is a dot matrix panel as in the first embodiment, the luminance of light emitted from a region adjacent to the lighting portion of the indicator lamp 2 in the backlight region 25 may be set to be higher than the luminance of light emitted from a region opposite to the lighting portion of the indicator lamp 2 in the backlight region 25 in a state where at least a part of the indicator lamp 2 is lit, as in the second embodiment.
In the second embodiment, the entire backlight region 25 may be configured to emit light uniformly in a state where at least a part of the marker lamp 2 is turned on.
In the above-described embodiment, the light-emitting panel 20 may be divided into a plurality of regions, and each region may be independently lit, but the configuration illustrated in the above-described embodiment may not be used. For example, the light-emitting panel may be formed of an inorganic EL panel, a plasma light-emitting panel, or the like.
In the above embodiment, when the process proceeds to step SP5 via step SP2, the brightness of the light emitted from the display 5 may be set to be higher than the brightness of the light emitted from the stop lamp region 21. In the case where the flow proceeds to step SP5 via step SP2, the luminance of the light emitted from the display monitor 5 may not be decreased.
In the above embodiment, the transmissive display 50 is configured to be capable of RGB color display, but may be monochrome, for example.
In the above embodiment, a reflecting plate that transmits light from the light-emitting panel 20 side and reflects light from the light-transmitting display 50 side may be disposed between the light-transmitting display 50 and the light-emitting panel 20. In this case, the display can be a reflective display in the daytime.
As described above, according to the present invention, it is possible to provide a vehicle lamp having excellent attention calling performance, and to use the vehicle lamp in the field of vehicles such as automobiles.
