Manufacture, installation, provision, and use of passenger cabin LED tube camera systems used as passenger lighting in passenger cabin of passenger rail cars, bus cars, passenger ships, passenger aircraft, etc., as well as their transport, storage, and assembly From the field of providing and selling the equipment and fixtures required for installation and the lighting and monitoring systems constructed by them, the materials required for those materials, machinery and components, such as wood, stone, and various fibers Of plastics, various metal materials, etc., electronic components incorporated in them, the field of control-related equipment integrating them, the field of various measuring instruments, the facilities and equipment The field of power machinery that drives the power, the field of electricity and the source of energy that is electricity, the field of oil, such as the field of oil, is generally referred to as the industrial machine, furthermore, such equipment and instruments are tested and researched, Fields related to their display, sales, import / export, general, results of their use, and fields related to the collection and transportation of garbage generated during the operation of equipment and instruments for making them, and their garbage There are few unrelated technical fields, such as the recycling field that efficiently recycles waste and other new fields that cannot be anticipated at this time.

(Points of interest)
As digital miniature cameras become smaller, lighter, and cheaper, security cameras are being installed in various places, such as on streets where a large number of unspecified people come and go, in public places, inside buildings, stores, and warehouses. In addition, in addition to installation in buildings, etc., in recent years, with the spread of back cameras and drive recorders to general vehicles, technology to record around the vehicle while the vehicle is running, Security cameras have been installed and used in various fields, such as technology for automatically recording the damage caused by accidents during parking and vandalism such as car vandalism.

    Despite these advances in security camera technology, security cameras have been installed in decks and deck aisles, for example, in passenger compartments of Shinkansen passenger vehicles that various passengers board. There is a risk that various accidents and crimes may occur even indoors, and it is expected that in the future, there will be a need to provide a technology that enables the entire room to be recorded.

(Conventional technology)
Proposals that reflect this situation and offer a breakthrough are not uncommon. For example, as typified by the following Patent Document 1 (1), an LED having an additional function unit including a wireless communication unit and an imaging unit for capturing a still image or a moving image and serving as a light source An LED lighting device system comprising: an LED lighting device provided inside a straight tubular cover including a light transmitting portion; and a portable terminal capable of wirelessly communicating with the LED lighting device via a wireless communication unit. The mobile terminal, when placed in an area where communication with the wireless communication unit is possible, displays information indicating that there is a camera around the mobile terminal. The user of the terminal can recognize that there is a camera in the vicinity, and as a result, those who intend to commit a crime are more likely to give up committing the crime and reduce the crime prevention effect. Higher When an LED illuminator is mounted on an existing fluorescent lamp socket as shown in Patent Document 1 (2) or an existing fluorescent lamp, and the LED illuminator is turned on, a low-frequency drive power is used. There was a drawback that the lighting state of the LED lamp was flickered due to the ripple included in the current, but a switching type step-down DC / DC converter composed of a switching transistor, a transformer, and a commutation diode was used as a power supply. In the LED lighting device to be used, the primary coil of the transformer is connected between the switching transistor and the LED light emitting unit, the circuit constituting the power supply for driving the sensor system is connected to the secondary coil, and the space on the component mounting surface is sufficient. To facilitate integration of sensor systems into LED lighting devices In both cases, LED lighting devices and the like that make it possible to avoid that the fluctuation of the power consumption of the sensor system has an adverse effect on the lighting condition of the LED lighting device of the LED lighting device and stabilize the lighting condition of the LED lighting device are found. .

However, the LED lighting device system as disclosed in the former patent document 1 (1) includes an image pickup unit and an additional function unit including a wireless communication unit capable of communicating with an external portable terminal in the LED lighting device. It can be said that it is installed as a lighting on the ceiling of a building, etc., and is suitable for recording images of accidents and crimes that occurred under the lighting, but it is suitable for passenger vehicles such as railways and buses. No technology has been shown that can set the angle of view of the imaging unit to a wide angle in the cabin, below the lighting, and in a range where crime tends to occur frequently. It is not possible to capture images well, and only obtains imaging data in a limited angle of view range, and there is a possibility that a crime may be committed at a position where blind spots occur. LED lighting represented by literature 1 (2) Cannot save recorded data when the power is cut off or a power failure occurs, especially in a usage environment where the power is repeatedly turned on and off every day, and power failures occur due to traffic accidents, railway accidents, disasters, etc. It is expected that fatal drawbacks will occur in passenger vehicles that are easy to use.
