Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railcar indoor lighting device, and more particularly to a lighting device suitable for improving economy and configuring a comfortable indoor environment.

[Conventional technology]

Conventionally, in this type of lighting device, a lighting fixture is provided independently of direct lighting and indirect lighting, and a method of mounting the lighting fixture on the body member is adopted.

A device related to this type of device is disclosed in, for example,
63-198203, JP-A-63-158704, JP-A-63-160103
And the like.

[Problems to be Solved by the Invention]

In the above-mentioned conventional technology, since separate fixtures for direct lighting and indirect lighting are required, the vehicle body structure becomes complicated in terms of the mounting space and the mounting position, and the mounting is performed by stacking on the body member. However, a troublesome work such as drilling on the vehicle body member is required, and no consideration is given to economy and workability, which is a problem.

The object of the present invention is to achieve a comfortable lighting environment and
Its purpose is to simplify the configuration.

[Means for solving the problem]

The above object is to provide two rows of lamp fixtures arranged on the ceiling of the vehicle along the longitudinal direction of the vehicle, and a reflection as a ceiling plate arranged above the lamp fixture at a predetermined distance in parallel with the lamp fixture. And a light shield plate disposed below the light fixture in parallel with the light fixture at a predetermined distance. The reflector plate is provided with the two rows of light fixtures and their ballasts. The two light shield plates are provided with a space through which light passes in the width direction of the vehicle body, and the space through which light passes between the end portions of the two light shield plates and the reflection plate in the width direction of the vehicle body. Can be achieved by providing.

[Work]

Direct light from the two lighting fixtures is emitted downward from the space between the two light shield plates, and reflected light is emitted from between the light shield plate and the reflector in the width direction. Therefore, both direct light and reflected light can be obtained.

Further, since the reflector is a ceiling plate in the interior of the vehicle, and the lighting fixture and its ballast are attached to the reflector, the structure can be simplified.

〔Example〕

In order to facilitate understanding of the present invention, a general lighting device will be described first.

FIG. 3 is a plan view of the general arrangement of a general vehicle lighting device,
FIG. 4 is a side view thereof, and FIG. 5 is an enlarged cross-sectional view thereof, in which interior lighting is performed by a lamp fixture 3 provided on a ceiling portion 2 of a vehicle body 1. FIG. 6 and FIG. 7 show sectional views of a vehicle in the case of indirect lighting which has been generally adopted in the past, in which a lighting device 3'for direct lighting and a lighting device 4 for indirect lighting are independently provided. Are arranged, and the configuration is complicated.

An embodiment of the lighting device of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view showing a state in which the lamp fixtures 5 and 5 ′, the light shielding plates 6 and 6 ′, and the reflector plate 7 are mounted at fixed positions on the ceiling portion 8. The luminous flux emitted from the lamp fixture 5 Due to the action of the light-shielding plates 6 and 6 ', the light beams are directly distributed in the range of the light beams 9 and 9', and the light beams from the lamp fixture 5'are directly distributed in the range of the light beams 10 and 10 '. As a result, the seats 11 and 11 'are mainly directly illuminated. Further, the passage portion 12 can also obtain sufficient illuminance as a passage.

Next, the luminous fluxes radiated from the lighting fixtures 5 and 5 ′ are
The light is also distributed in the direction of the upper reflection plate 7, and the indirect light fluxes 13 and 13 'reflected by the reflection plate 7 are distributed in various directions from the gap between the reflection plate 7 and the light shielding plates 6 and 6'. ,
It is possible to perform dimming illumination (indirect illumination) on the upper portion (ceiling portion) of the room.

FIG. 2 shows a detailed cross-sectional view of the mounting portion of the lighting fixtures 5 and 5 ', including the roof 14, the ceiling frames 15 and 15', and the ceiling boards 16 and 1.
In the ceiling structure consisting of 6 ', two sets of lighting fixtures are combined into one set of lighting fixtures, and the lighting parts 17, 17' and the ballasts 18, 1
The 8'mounting plate 19 has a wide structure so that the ceiling plate 1
Similar to 6 and 16 ', the mounting plate 19 is also used as a reflection plate to form a ceiling member of the vehicle body.

〔The invention's effect〕

According to the present invention, the direct light of the two lamps is emitted downward from the space between the two light shield plates, and the reflected light is emitted from between the light shield plate and the reflector in the width direction. For this reason,
It is possible to obtain both direct light and reflected light. In addition, the reflector is a ceiling plate inside the vehicle,
Since the lamp fixture and its stabilizer are attached to the reflector, the structure can be simplified.
