Abstract

A rail vehicle lighting device includes: a plurality of short lighting fixtures assembled into a long lighting fixture having a shape matching with a shape of an irregular interior decoration. Each of the short lighting fixtures is provided with a section body. A light source is provided on the section body. The section body is twisted such that included angles between each of the light sources and a horizontal plane are consistent. In the rail vehicle lighting device, the plurality of short lighting fixtures is assembled into the long lighting fixture having the shape matching with the shape of the irregular interior decoration, thereby satisfying a requirement on a shape of a lighting fixture. By arranging the twisted section body, respective points of the long lighting fixture have consistent light source illumination angles, thereby achieving a satisfactory illumination effect inside a carriage having an irregular interior decoration, and accordingly improving the appearance of the carriage.

First claim

1 . A rail vehicle lighting device, wherein the lighting device comprises a lighting fixture having a shape matching with a shape of an irregular interior decoration.

2 . The rail vehicle lighting device of claim 1 , wherein the lighting fixture comprises a plurality of short lighting fixtures that are assembled into a long lighting fixture having a shape matching with the shape of the irregular interior decoration.

3 . The rail vehicle lighting device of claim 2 , wherein each of the short lighting fixtures comprises a section body, a light source on the section body, the lighting fixture comprises a plurality of light sources, and the section body is twisted such that included angles between each of the light sources and a horizontal plane are consistent.

4 . The rail vehicle lighting device of claim 1 , wherein the irregular interior decoration has a wavy shape having ups and downs in a horizontal direction and/or a vertical direction.

5 . The rail vehicle lighting device of claim 2 , wherein each of the short lighting fixtures comprises a housing comprising a lamp body and a lampshade, wherein a section body is provided in the housing.

6 . The rail vehicle lighting device of claim 2 , wherein each of the short lighting fixtures is fixed with an L-shaped mounting sheet through a first mounting clasp seat, and the L-shaped mounting sheet is fixed with the irregular interior decoration.

7 . The rail vehicle lighting device of claim 6 , wherein a gasket is provided between the L-shaped mounting sheet and the irregular interior decoration, and a thickness of the gasket is sized and configured such that distances between each of the light sources and a top plate of a vehicle body are the same.

8 . The rail vehicle lighting device of claim 3 , wherein two light sources with different illumination angles are provided on the section body, one light source irradiates toward a top plate of a vehicle body, and the other light source irradiates toward an interior of a carriage.

9 . The rail vehicle lighting device of claim 2 , wherein each of the short lighting fixtures is provided with a wiring groove.

10 . The rail vehicle lighting device of claim 2 , wherein each of the plurality of short lighting fixtures and a power supply are fixed and integrated together.

11 . The rail vehicle lighting device of claim 2 , wherein the plurality of short lighting fixtures are linked with each other via terminals.

12 . The rail vehicle lighting device of claim 1 , wherein:
the lighting fixture comprises a lamp tube portion and a lamp body portion; the lamp tube portion comprises a lamp tube section, which, after being stretched and molded, has a shape matching with a shape of the irregular interior decoration; a light source is provided on the lamp tube section; and the lamp tube section is twisted and molded such that included angles between each of the light source and a horizontal plane are consistent.

13 . The rail vehicle lighting device of claim 12 , wherein the irregular interior decoration has a wavy shape having ups and downs in a horizontal direction and/or a vertical direction.

14 . The rail vehicle lighting device of claim 12 , wherein the lamp tube portion is fixed with the lamp body portion through a second mounting clasp seat, and the lamp body portion is fixed with the irregular interior decoration.

15 . The rail vehicle lighting device of claim 14 , wherein a height of the second mounting clasp seat is sized and configured such that the distances between each of the light source and the top plate of the vehicle body are the same.

16 . The rail vehicle lighting device of claim 12 , wherein the lamp body portion comprises a V-shaped base plate, a second mounting clasp seat is fixed on one side surface of the V-shaped base plate, and another side surface of the V-shaped base plate is fixed with the irregular interior decoration.

17 . The rail vehicle lighting device of claim 16 , wherein a plurality of mounting plates is further provided on the V-shaped base plate, and each of the mounting plates is provided with a wiring groove.

18 . The rail vehicle lighting device of claim 17 , wherein each of the mounting plates is provided with a power supply.

19 . The rail vehicle lighting device of claim 12 , wherein the lamp tube section is provided with a light source mounting base and a lampshade mounting base.

20 . The rail vehicle lighting device of claim 2 , wherein the irregular interior decoration has a wavy shape having ups and downs in a horizontal direction and/or a vertical direction.
