Abstract

The invention relates to the field of railway signal lamps, and provides an LED railway signal lamp, which is used to solve the problems of poor versatility, difficult maintenance and the need to renovate the original railway system in the current single-color LED railway signal lamps. The LED railway signal lamps are composed of lamps and Composed of load resistors, the lamp includes a lamp base and a lamp body, and the lamp body is equipped with a dual-channel LED light source, a photosensitive resistor, an LED lamp board and a dual-channel LED drive circuit module. The invention improves the versatility of the product, facilitates maintenance, avoids the transformation of the railway system, and realizes "failure-oriented safety".

Description

technical field [0001] The invention relates to the field of railway signal lamps, in particular to an LED railway signal lamp. Background technique [0002] The railway signal light is an indispensable device in the railway system. The different colors of the railway signal light can convey information about the operating conditions of the rolling stock, the status of the driving equipment, and the driving instructions to the railway personnel. Traditional railway signal lights generally use incandescent bulbs or halogen bulbs as light sources. These two types of ordinary bulbs are thermal radiation light sources, which have the advantages of simple structure, low cost, and good color rendering, but have the following disadvantages: [0003] (1) The service life is short, about 3000h; [0004] (2) Low luminous efficiency, 40W light efficiency is only 10lm / W; [0005] (3) Poor adaptability to fluctuations in power supply voltage; [0006] (4) Not resistant to vibration, e...
