Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] The railway vehicle lighting device described in the present invention is mainly used for compartment lighting with special-shaped interior decoration. The railway vehicle lighting device according to the present invention is arranged between the roof plate 2 of the vehicle body.

[0022] Such as figure 1 and figure 2 As shown, the rail vehicle lighting device is composed of several short lamps 3, which are spliced ​​into long lamps 4 according to the shape of the wave-shaped interior 1, and the shape of the long lamps 4 matches the shape of the wave-shaped interior 1. The splicing form not only meets the shape requirements of the lamps, but also facilitates the heat dissipation of the lamps.

[0023] The short lamp 3 includes a housing composed of a lamp body 6 and a lampshade 7 , and a profile body 5 arranged inside the housing.

Abstract

A rail car lighting device comprises a plurality of short lamps. The short lamps are spliced into a long lamp matched with a special-shaped interior in shape. Sectional bars are arranged in the short lamps. Light sources are arranged on the sectional bars. The irradiation angles of the included angle between all sections of light sources and the horizontal plane are consistent through sectional bar twisting. The short lamps are spliced into the long lamp matched with the special-shaped interior in shape, and accordingly the requirement for the shape of the lamp is met. The twisted sectional bars are arranged inside, the light source irradiation angles of points of the long lamp are consistent, the requirement for the lighting effect in a carriage of the special-shaped interior is met, and the carriage beautifying degree is further improved.

Description

technical field [0001] The invention relates to a lighting device, in particular to a rail vehicle lighting device. Background technique [0002] With the development of railway passenger vehicles, people not only have higher requirements for the operating speed of vehicles, but also have higher requirements for ride comfort and interior beauty. At present, many vehicles use special-shaped interior decorations to improve the aesthetics of the carriages, such as wavy interior decorations. However, LED lights and fluorescent lamps used in traditional interior lighting equipment are used as line, surface or point light sources to achieve lighting. For new The wavy interior structure cannot achieve better lighting effects. Contents of the invention [0003] The main purpose of the present invention is to solve the problem of how to meet the interior lighting requirements for special-shaped interior decoration structures, and provide a rail vehicle lighting device. [0004] F...
