On the other hand, on the ceiling of the bus facing the central passage, a fluorescent lamp, which is the main room light, is arranged in the center in the front and rear direction so that the interior is illuminated when traveling outside at a relatively dark night. It has become. When the passenger needs to go to bed with a passenger seated on the seat like a night bus, the interior of the main room light is partially turned off to darken the room. However, even if the main room light is partly turned off to darken the room, the vicinity of the lit indoor light is relatively bright and passengers who sleep in the nearby seat may not be able to sleep sufficiently due to the brightness. is there.
[0003]
On the other hand, in recent buses, a cooling device is provided, and cold air blown out by an air conditioning unit that generates cold air arranged under the floor is extended in the traveling direction of the vehicle on both sides of the ceiling above the side window of the passenger compartment. One that blows air to a pair of cooler ducts provided is known. The cooler duct is provided with a console in which a grill for blowing cool air toward each seat at a predetermined interval and a reading lamp are integrally provided. In view of this, there has been proposed a console in which a room light is built in and light from the light source of the room light is directed from the side surface of the console toward the center of the room (for example, see Patent Document 1).
