led long distance tunnel light

Abstract

The invention discloses an LED long-distance tunnel lamp, which comprises a lamp housing. A lamp cap assembly and a fixing plate for fixing the lamp cap assembly are arranged inside the lamp housing. The lamp cap assembly includes a remote lamp cap assembly for remote light distribution, The mid-distance lamp cap assembly for mid-distance light distribution, the short-distance lamp cap assembly for short-distance light distribution, the long-distance lamp cap assembly, the mid-distance lamp cap assembly and the short-distance lamp cap assembly are arranged on the fixing plate together. The invention provides an LED long-distance tunnel light with simple structure, uniform illuminance over long distances, long-distance lighting arrangement and meeting the illuminance requirements of railway tunnels.

Description

technical field [0001] The invention belongs to the technical field of lighting, and relates to a lamp, in particular to an LED long-distance tunnel lamp. Background technique [0002] At present, gas discharge lamps such as metal halide lamps and electrodeless lamps are mostly used in tunnels as light sources. In order to achieve the minimum illumination of railway tunnels, gas discharge lamps and electrodeless lamps with higher power should be used. For example, 70W gas discharge lamps are used in tunnels. Due to the high power and the large volume of the bulb, the reflector used is designed to have a limited wide angle on one side of the floodlight, resulting in a problem that the illumination directly below the lamp is very high and the distance is very weak. However, in order to achieve the minimum illumination of the railway tunnel Requirements, that is, the minimum illuminance at any position between the two lamps must be greater than 0.51x, so the designed 70W gas di...

Problems solved by technology

[0002] At present, gas discharge lamps such as metal halide lamps and electrodeless lamps are mostly used in tunnels as light sources. In order to achieve the minimum illumination of railway tunnels, gas discharge lamps and electrodeless lamps with higher power should be used. For example, 70W gas discharge lamps are used in tunnels. Due to the high power and the large volume of the bulb, the reflector used is designed to have a limited wide angle on one side of the floodlight, resulting in a problem that the illumination directly below the lamp is very high and the distance is very weak. However, in order to achieve the minimum illumination of the railway tunnel Requirements, that is, the minimum illuminance at any position between the two lamps must be greater than 0.51x, so the designed 70W gas discharge lamp lighting distance can only be about 20 meters, the number of tunnel lighting is large, and because the railway tunnel light source requires 24 hours Turned on, the high-power light source consumes a lot of power, causing a lot of energy waste
