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 parts, such as wood, stone, and various fibers. Fields that provide types, plastics, various metal materials, etc., fields of electronic parts incorporated in them and control-related equipment that integrates them, fields of various measuring instruments, fields of power machinery that moves the equipment and appliances, and their energy In the fields of electricity and oil, which are the power and energy sources, which are generally called industrial machinery, as well as testing and researching those facilities and appliances, and exhibiting, selling, and importing and exporting them.

(Point of interest)
With the miniaturization, weight reduction, and cost reduction of small digital cameras, the installation of security cameras on the streets where an unspecified number of people come and go, in public outdoors, in buildings, stores, warehouses, etc. is progressing, and the security effect In addition to being installed in buildings, in recent years, with the spread of back cameras and drive recorders in general vehicles, technology for recording the surroundings of vehicles while the vehicle is running has become available. Security cameras are being installed and used in various fields, such as technology that automatically records accident damage caused while parking and incident damage such as on-board vandalism.

Despite these advances in security camera technology, for example, security cameras have been installed in decks and deck aisles in the passenger compartments of Shinkansen passenger vehicles on which various customers ride. There is a risk that various accidents and crimes will occur indoors, and it is expected that in the future, it will be required to provide technology that enables recording in the entire cabin.

(Conventional technology)
Proposals that reflect this situation and provide a solution to this situation are not unheard of. For example, as typified by the one proposed in Patent Document 1 (1) below, an LED having an additional functional 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. Is an LED lighting device system having an LED lighting device provided inside a straight tubular cover including a light transmitting portion, an LED lighting device, and a mobile terminal capable of wireless communication via a wireless communication unit. Is capable of wireless communication, and when the mobile terminal is placed in the communicable area with the wireless communication unit, it is supposed to display information on the screen informing that there is a camera in the vicinity, and is portable. The user of the terminal can recognize that there is a camera in the vicinity, and as a result, those who are thinking of committing a crime are more likely to give up the crime and prevent the crime. Low drive power when an LED lighting lamp is attached to an existing socket for a fluorescent lamp and turned on, as seen in Patent Document 1 (2) or one that can be increased. There was a drawback that the lighting state of the LED lighting lamp flickers due to the ripple content contained in the frequency current, but the power supply is a switching type step-down DC / DC converter consisting of a switching transistor, a transformer and a commutation diode. In the LED lighting device used as, the primary coil of the transformer is connected between the switching transistor and the LED light emitting part, and the circuit that constitutes the power supply that drives the sensor system is connected to the secondary coil to save space on the component mounting surface. It can be sufficiently secured to facilitate the incorporation of the sensor system into the LED lighting device, and it is possible to prevent fluctuations in the power consumption of the sensor system from adversely affecting the lighting state of the LED lighting of the LED lighting device. There are some LED lighting devices that can stabilize the lighting state of LED lighting.

However, the LED lighting device system as shown 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 mobile terminal in the LED lighting device. Therefore, it can be said that it is installed as a lighting on the ceiling of a building and is suitable for recording images of accidents and crimes that occurred under the lighting, but for passenger vehicles such as railroads and buses. No technology has been shown that allows the imaging unit to have a wide angle of view in the cabin, below the lighting, where crime tends to occur frequently, and efficiency is achieved in the cabin of a vehicle that is long in the direction of travel. It is not possible to take a good image, and only the imaged data in a limited angle range is obtained, and there is a risk that the crime will be committed at a position that becomes a blind spot. LED lighting devices such as those represented by Document 1 (2) cannot save recorded data in the event of a power outage or power outage, and are in a usage environment where the power is turned on and off every day, and moreover, traffic accidents and railways. It is expected to be a fatal drawback for passenger vehicles that are prone to power outages due to accidents and disasters.

Since it is not possible to take a wide image in the direction, it is not possible to take an image of the entire passenger cabin, and safety such as strength, durability and fire resistance to withstand the vibration during vehicle driving required for mounting on a vehicle. In addition to being difficult to satisfy the characteristics, there remains the drawback that the imaged data is lost due to an unexpected power outage, and the configuration for eliminating these drawbacks remaining in the conventional type is described.
