Abstract

PURPOSE:To secure both direct and indirect illumination without providing an exclusive appliance but with a simple structure by providing a reflection plate and douser in parallel at a specified intervals, respectively, on the top and the bottom of light apparatus arranged in plural numbers in the longitudinal direction of the ceiling portion of a rolling stock. CONSTITUTION:Beams radiated from a light apparatus 5 disperse within the range of direct beams 9, 9' by the action of dousers 6, 6' and beams from a light apparatus 5' disperse within the range of direct beams 10, 10'. These beams are direct illumination for seats 11, 11' portions and also have enough illuminance for the passage portion 12. Beams radiated from light apparatus 5, 5' also disperse toward the direction of a reflection plate 7 on the upper portion. Indirect beams 13, 13' reflected by the reflection plate 7 disperse to various directions through gaps between the reflection plate 7 and the dousers 6, 6' and makes an adjusted illumination (indirect illumination) of the upper portion of the room (ceiling portion).

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting device for the interior of a railway vehicle, and particularly to a lighting device suitable for improving economic efficiency and creating a comfortable indoor environment.

[Prior Art] Conventionally, in this type of lighting device, lamp fixtures are provided independently for direct lighting and indirect lighting, and a method has been adopted in which the lighting fixtures are mounted in layers on vehicle body members.

Related devices of this type include, for example, Japanese Patent Application Laid-open No. 6
3-198203, JP-A-63-158704, JP-A-637160103, and the like.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, separate fixtures are required for direct lighting and indirect lighting, which complicates the vehicle body structure in terms of mounting space and mounting position. Since the holes are attached to the vehicle body member overlappingly, drilling holes in the vehicle body member requires cumbersome work such as machining, and this has been a problem because the arrangement has not been done in terms of economy and workability.

An object of the present invention is to solve the above-mentioned problems, provide a comfortable indoor environment, and improve economic efficiency and workability.

[Means for Solving the Problems] The above object can be achieved by arranging the light fixture and the end plate so that direct lighting and indirect lighting can be achieved at the same time, and by configuring the light fixture as a ceiling member.

[Function] The luminous flux from the illumination part of the lamp fixture installed on the ceiling is directly distributed only in a certain range by the shield plate, and the luminous flux radiated to the ceiling reflector is distributed through the gap between the ceiling plate and the ceiling plate. The light is distributed as indirect lighting. This allows for high-quality lighting without any unnatural appearance.

[Example] In order to facilitate understanding of the present invention, a radial illumination device will first be described.

Fig. 3 is a plan view of the general arrangement of a general vehicle lighting system, Fig. 4 is a side view thereof, and Fig. 5 is an enlarged sectional view of the vehicle body.
The room is illuminated by a lamp 3 installed on the ceiling 2 of the room. Figures 6 and 7 show cross-sectional views of vehicles for indirect lighting, which has been commonly used in the past, with lamps 3 for direct lighting and lamps 4 for indirect lighting arranged independently. The structure is complicated.

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

Fig. 1 shows a cross-sectional view of the lamp 5.5', the luminaire 11ii 6.6', and the reflector 7 installed in fixed positions on the ceiling 8. The light flux is distributed within the range of direct light flux 9.9' by the action of the tip plate 6.6', and the light flux from the lamp fixture 5' is directly distributed within the range of 10.9'.
Light is distributed within a range of 10'. As a result, the waist 1111.
The 11' section will be mainly directly illuminated. In addition, the passage portion 12 can also have a sufficient width as a passage.

Next, the luminous fluxes radiated from the lamps 5 and 5' are also distributed in the direction of the upper reflecting plate 7, and the indirect luminous fluxes 13 and 13' reflected by the reflecting plate 7 are blocked by the reflecting plate 7. Light is distributed in various directions through the gaps between the front plates 6 and 6', and the upper part (ceiling part) of the room can be dimmed (indirectly illuminated).

FIG. 2 shows a detailed sectional view of the mounting part of the light fixture 5.5', and shows the roof 14. Ceiling frame 15.15' and ceiling board 1
6.In a ceiling structure consisting of 16′, two sets of lighting fixtures are installed in one
By combining the light fixtures into a set and making the mounting plates 19 of the lighting section 17.17' and ballast 18.18' wide, the mounting plates 19 can also be used as reflectors in the same way as the ceiling panels 16.16'. The ceiling member of the vehicle body is constructed using the following construction.

According to this embodiment, it is possible to construct an indoor lighting device that is highly economical and provides a comfortable indoor environment.

[Effects of the Invention] As explained above, according to the lighting device of the present invention, both direct lighting and indirect lighting can be achieved with a simple structure without the need for special equipment. Similar to the above, it is possible to ideally distribute light in the room, provide high quality lighting without any unnatural appearance, and create a comfortable indoor environment. Additionally, since no special equipment is required, the design and body structure of the vehicle can be easily integrated, resulting in significant power savings.

Furthermore, since the light fixture can be configured as a ceiling member of the vehicle body, troublesome work such as drilling holes in the vehicle body member is not necessary. These features significantly improve economic efficiency and workability.
