Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to an LED lamp tube for a train compartment. Background Art

[0002] In recent years, with the rapid development of the national economy, road congestion has become increasingly serious. Therefore, major cities are vigorously developing train transportation such as motor vehicles, high-speed railways, and subways to alleviate ground road traffic congestion and facilitate people's travel. Motor vehicles and high-speed railways often have to go through tunnels, and subways are running underground all year round, which has high requirements for lighting. Not only are lighting fixtures required to have the characteristics of power saving, high brightness, low glare and long life, but also to ensure uninterrupted lighting. Light-emitting diodes (LEDs) have become a new generation of solid-state light sources due to their advantages such as energy saving, environmental protection, long life and earthquake resistance, and have gradually replaced various traditional light sources. They are more widely used in places with high traffic density and long-term uninterrupted lighting, such as train carriages, platforms, aisles and large transportation hubs.

[0003] A Chinese patent with announcement number CN205332047U discloses an LED ceiling light for a train carriage, comprising a shell, a connecting rod, a side cover, a sealing ring, and an LED module. The shell is a long hollow cube structure, and the upper and lower end surfaces of the shell are fixedly provided with bosses in the same direction as the long axis direction of the shell, the bosses are provided with through holes penetrating the left and right end surfaces of the bosses, the connecting rod is fixed in the through holes, the side cover and the connecting rod are fixed to the left and right ends of the shell by screws, and a sealing ring is provided at the connection between the shell and the side cover; the inner sides of the upper and lower end surfaces of the shell are provided with mounting grooves in the same direction as the long axis direction of the shell, the LED module is clamped in the mounting groove in the shell, the LED module comprises an aluminum substrate, an LED light source arranged on the aluminum substrate, and a driving power supply for driving the LED light source. The utility model solves the problems of low light efficiency and light utilization rate of train lighting lamps, easy glare and poor sealing performance of lamps. However, the above patent still has the problem of poor heat dissipation effect of the lamp tube, which causes the temperature of the lamp tube to be too high, which will affect the life of the lamp, and also pose a threat to personal safety, with the risk of scalding the skin. At the same time, there is also the problem of inconvenient installation or replacement. Therefore, we propose a train carriage LED lamp to solve the above problems. Utility Model Content
