Abstract

The invention relates to an LED two-sided direction signal lamp which comprises a first constant-current drive unit, a second constant-current drive unit, a first LED lamp, a second LED lamp, an interlocking unit and a blink control unit, wherein an external direct-current power supply respectively drives the first LED lamp and the second LED lamp through the first constant-current drive unit and the second constant-current drive unit; the blink control unit is arranged between the direct-current power supply and the first constant-current drive unit or the direct-current power supply and the second constant-current drive unit and used for controlling the blink of the first LED lamp and the second LED lamp; and the interlocking unit is connected between the first constant-current drive unit and the second constant-current drive unit for controlling the first LED lamp and the second LED lamp for realizing the interlocking. The LED two-sided direction signal lamp has the advantages of high efficiency, long service life, high brightness and good shock resistance, can be suitable for the wide voltage input range, can realize accurate interlocking control on the two-sided LED lamp, and effectively avoids the safety accidents.

Description

technical field [0001] The invention relates to a signal lamp at the rear of a train, and more specifically relates to an LED double-sided signal lamp circuit. Background technique [0002] At present, incandescent lamps are basically used as signal light sources in the railway industry. Incandescent lamps have the disadvantages of low electrical efficiency, short life, low illumination, poor vibration resistance and single light color. [0003] With the improvement of LED cold light source technology on the one hand, and the requirement of signal light source for locomotive speed-up on the other hand, LED signal light source has become a new technology in the field of railway signal. Due to its light-emitting principle, LED light source has the advantages of high brightness, good directionality, long life and power saving. It will eventually replace the existing incandescent light source in the field of railway signaling and become the mainstream light source of signal ligh...
