The invention relates to a lamp strip in a passenger room for a railway vehicle. The lamp strip comprises a lamp strip top plate and a lamp cover, wherein the lamp strip top plate is fixed on a top plate in a vehicle; the lamp cover is positioned below the lamp strip top plate; a rotary component with a rotary shaft is fixed on the outer end of the lamp cover; the inner end of the lamp cover is fixedly provided with a rapid connecting mechanism; the lower side surface of the lamp strip top plate is fixedly provided with a T5 lamp seat and a T5 electronic ballast; the T5 lamp seat is internally provided with a T5 lamp; the outer end of the lamp strip top plate is provided with a rotary shaft support component which allows the rotary shaft of the rotary component to enter and rotate; the inner end of the lamp strip top plate extends downward and is folded outward; and the folding edge folded outward is matched with the rapid connecting mechanism to achieve the fixing of the lamp cover. A T5 fluorescent lamp tube is adopted for the light source provided by the invention, compared with the traditional adopted T8 fluorescent lamp tube, the occupied space of the lamp strip is saved by nearly one third, and the ballast with smaller volume is redesigned according to the space requirement; and the lamp cover in the dark space of the lamp strip in the passenger room is provided with a sound transmitting hole, a loud speaker in the passenger room is built in the passenger room, and the space in the vehicle is fully utilized.
Description
technical field [0001] The invention relates to a light strip for a passenger compartment of a railway vehicle, and belongs to the technical field of railway passenger vehicle electric lighting. Background technique [0002] The traditional car light belt uses T8 fluorescent tubes, which are connected to the car body frame as a whole, and the size is too large. Due to the small space in the low-floor EMU, this traditional light belt structure cannot meet the requirements. In addition, the bottom surface of the air-conditioning duct in the passenger room is close to the roof of the car, so the speaker cannot be directly installed on the roof of the car. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a light strip for a railway vehicle passenger compartment. [0004] In order to solve the above technical problems, the present invention provides a rail...
