LED (light emitting diode) lighting lamp of locomotive or bullet train with reflectors

Abstract

The invention discloses an LED lighting lamp of a locomotive or bullet train with reflectors. The LED lighting lamp comprises a lamp casing with a rear cover, and the front end of the lamp is provided with a transparent lampshade; the inside of the lamp casing is provided with a mounting board with a lamp holder, and the mounting plate divides the lamp casing into a front cavity and a rear cavity; the lamp holder is provided with a stand column perpendicular to the mounting plate, the side surfaces and the top surface of the stand column are both provided with LED lamp panels., and the inside of the rear cavity of the lamp casing is provided with a power source module for powering the LED lamp panels; the lamp holder is also provided with reflectors which are used with the LED lamp panels on the side surfaces of the stand column in pairs. According to the LED lighting lamp of the locomotive or bullet train with the reflectors, the LED light sources replace traditional filament lamps, halogen tungsten light sources or xenon metal halide lamp light sources; the front portion and the rear portion of the lamp casing are provided with the lampshade and the rear cover, so that the front protection and the rear protection of the lighting lamp can be separately achieved, further the service life of the lighting lamp cannot be affected by external environmental factors during the usage of the lighting lamp and functional maintenance of the lighting lamp is not required within a maintenance period.

Description

technical field [0001] The invention belongs to the technical field of outdoor lighting, and relates to a lighting fixture for a railway locomotive or a train, in particular to an outdoor LED lighting fixture for a railway locomotive or a train with a reflector. Background technique [0002] At present, incandescent, tungsten-halogen light sources or xenon metal halide light sources are generally used for outdoor and near lighting of conventional railway locomotives or bullet trains, but incandescent and tungsten-halogen light sources have disadvantages such as high energy consumption and short life; xenon metal halide lamps are high-pressure gas The discharge lamp category is a new type of gas discharge lamp. It is a new generation of energy-saving lighting source. It is named Xenon metal halide lamp because it injects "xenon" into the bulb and adds metal halide. Its light-emitting principle is activated by arc discharge. The gas in the bulb is ionized with the metal halide...

Problems solved by technology

[0002] At present, incandescent, tungsten-halogen light sources or xenon metal halide light sources are generally used for outdoor and near lighting of conventional railway locomotives or bullet trains, but incandescent and tungsten-halogen light sources have disadvantages such as high energy consumption and short life; xenon metal halide lamps are high-pressure gas The discharge lamp category is a new type of gas discharge lamp. It is a new generation of energy-saving lighting source. It is named Xenon metal halide lamp because it injects "xenon" into the bulb and adds metal halide. Its light-emitting principle is activated by arc discharge. The gas in the bulb is ionized with the metal halide to emit light, but although the xenon metal halide lamp has low energy consumption, it also has the obvious disadvantage of short life
