Problems solved by technology

However, in this structure, when the occupant of the vehicle visually confirms the information displayed through the vehicle meter device, at the same time he visually confirms the light of the upper limit of the visible light in the near-infrared light irradiated by the near-infrared light irradiation unit, and the occupant may be worried. give mixed impressions
[0012] Although the light of the wavelength (780-830nm) of the upper limit of visible light included in near-infrared light has poor sensitivity, the occupant can perceive it through visual confirmation.
Furthermore, since the infrared light projector of Patent Document 1 emits such near-infrared light including light of the upper limit wavelength of visible light toward the occupants in the form of a point light source, the luminosity per unit area of ​​the light of the upper limit of visible light is large. , the light is easily perceived by the occupant
Therefore, since light with a wavelength of the upper limit of visible light is perceived, there is a concern that the appearance of the lighting device will be impaired and the occupant may be given a complicated impression.

no. 1 approach

[0074] The vehicle display device 100 according to the first embodiment of the present disclosure is mounted on a vehicle, and is installed on a center console panel facing a seat where an occupant who is a visual observer sits. Such as figure 1 As shown, the vehicle display device 100 constitutes an instrument cluster that combines the analog display by the pointers 40a, 40b indicating the indicators 22a, 22b and the digital display by the image displayed on the image display 10, and displays information toward the visual recognition side. . Accordingly, the occupant on the visual recognition side with respect to the vehicle display device 100 can recognize the displayed information. The displayed information includes, for example, vehicle states such as vehicle speed, engine speed, remaining fuel level, engine cooling water temperature, electric motor current value, and abnormality of other vehicles. Examples of other displayed information include various information such ...

no. 2 approach

[0110] Such as Figure 5-9 As shown, the second embodiment is a modified example of the first embodiment. The second embodiment will be described focusing on points different from the first embodiment.

[0111] The vehicle display device 200 of the second embodiment can display the level of fuel efficiency in the vehicle. Specifically, such as Figure 5 As shown, in the display panel 220 , an eco display lamp 226 configured by forming the outline of the display area DA surrounded by the light-shielding area SA in the shape of the characters "ECO" is provided.

[0112] Such as Image 6 As shown, an eco-friendly visible light source portion 230a is disposed on the anti-visual confirmation side of the eco-friendly display lamp 226 of the display panel 220, and the eco-friendly visible light source portion 230a has a display light-emitting element 231a that emits visible display light. Like the visible light source unit 30 of the first embodiment, the display light emitting el...

no. 3 approach

[0125] Such as Figure 10 , 11 As shown, the third embodiment is a modified example of the first embodiment. The third embodiment will be described focusing on points different from the first embodiment.

[0126] Unlike the first embodiment, the near-infrared light irradiation unit 380 of the third embodiment is not arranged in the visible light source unit 30 . The near-infrared light irradiation part 380 of the third embodiment has a near-infrared light-emitting element 381, and the near-infrared light-emitting element 381 is arranged on the anti-visual confirmation side of the display panel 320, and is separated from the space where the visible light source part 30 is arranged. In the different spaces divided by the light-shielding wall 8 .

[0127] On the display panel 320, a near-infrared light-transmitting layer for transmitting near-infrared light including visible upper limit light is formed by printing at a position adjacent to the indicators 22a and 22b forming th...

Abstract

Provided is a vehicular display device that is mounted to a vehicle and displays information, the vehicular display device comprising: a near-infrared light irradiation unit (80, 280, 380, 480, 580, 680, 780, 880, 980, 1080, 1180) for irradiating a visible side with near-infrared light including light with a wavelength at the upper bound of visible light; and a simulation unit (3, 203, 303, 403, 503, 603, 703, 803, 903, 1003, 1103) for simulating light with a wavelength at the upper bound of visible light. Also provided is an imaging system that is disposed inside a vehicular display device for displaying information about a vehicle, and that illuminates and images an object to be imaged in the vehicle, the imaging system comprising: a near-infrared light irradiation unit; and an imaging unit (60) for imaging an object to be imaged that is illuminated by the near-infrared light irradiation unit. Light at the upper bound of visible light irradiated by the near-infrared light irradiationunit is simulated by the simulation unit provided in the vehicular display device.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2017-128258 filed on June 30, 2017, Japanese Patent Application No. 2018-64210 filed on March 29, 2018, and Japanese Patent Application No. filed on June 30, 2017 No. 2017-128260 and Japanese Patent Application No. 2018-90780 filed on May 9, 2018, the contents of which are cited here. technical field [0003] The present disclosure relates to a vehicle display device, an imaging system, and a lighting device.
