Train lights History

Date:Aug 17, 2019

         Train lights are a type of traffic lights installed on locomotives and used as lighting and signals to ensure the safety of railway transportation.

            Early train carriages lit oil lamps, then later changed to kerosene gas lamps, and incandescent lamps were gradually used in the early 20th century. After 1910, locomotives were installed with incandescent headlights which can light 300m distance. After 1950, fluorescent lamps began to be used in the carriers, bringing the interior illumination of the carriages to 100 to 300lx. Subsequently, because of the use of high-frequency power supply technology and three-color fluorescent lamps, lighting quality was significantly improved. 

In addition to the use of incandescent lighting 

         Except in special places, auxiliary lighting situations and luxury decorative lamps for superior trains that were using incandescent lights , fluorescent lamps had become the main light source for train locomotive lighting. After 1965, ultra-high-pressure spherical mercury xenon lamps were used on the locomotive headlights as a light source , which had an irradiating distance of more than 1000 m. The increase in irradiating distance has promoted the development of modern long-distance and high-speed trains.

     Now ,led technology has been widely used on train headlights.
