Description

The invention relates to the field of signal light devices of railway light signaling.

The task to which the claimed utility model is directed is to increase the level of safety at level crossings, which are objects of increased danger, due to the continuous and reliable direct monitoring of the operability (luminosity) of LED light-optical systems of a level crossing traffic light both in working and in non-working ("cold" ) states.

Known railway traffic light, RF patent B61L 5/18 256926 03/15/2012, with LED systems made in the form of aspherical lenses, on the inside of which are recesses for installing light emitters - LEDs. Monitoring is carried out according to the current consumption in working condition. The disadvantage of this invention is the lack of control of luminosity in the "cold" state.

Known traffic light LED railway, RF patent 27313, 7 B61L 5/18, 01/20/2003, containing a housing with a light source in the form of an LED matrix. The operability of light-optical systems is carried out by the method of measurement flowing through the light-optical current systems using firing relays in the running state.

A disadvantage of the known railway traffic lights is that none of the identified railway traffic lights has luminosity control in both the working and non-working ("cold") states, and the magnitude of the current consumption in the running state is monitored. This method of control does not allow to identify a malfunction of the LED system in advance of turning on the crossing signaling.

An analysis of the applied signal devices shows that this construction scheme is applied for the first time.

The specified technical result is achieved by the fact that the LED optical systems that are part of the crossing traffic light have an integrated light emission control system for LEDs, which makes it possible to evaluate their serviceability with a high degree of reliability. Light-emitting diode optical systems include: printed circuit boards with light-emitting diodes and electronic components, a housing in which photosensitive sensors for monitoring luminosity are placed, a set of lenses and a protective glass, the housing and the light-optical system are connected together by screw connections.

A general view of a traffic light is shown in the drawing.

Brief description of the drawing. The structure of the traffic light with LED light-optical systems with luminosity control includes: traffic light head with LED light-optical systems - 1; mast - 2; foundation - 3, swivel bracket - 4, transformer box - 5, road sign - 6 (single-track or multi-track railway), stairs - 7.

The proposed utility model operates as follows. The power supply unit of the LEDs generates current pulses with the specified characteristics. Photosensitive sensors receive light pulses generated by LEDs. The pulse power supply of the LEDs makes it possible to distinguish the effect on the photodetectors of external illumination (sunlight, light from headlights and others) from the emission of LEDs. The signals of the photodetectors are processed and fed into the control signal generation system. If the light emission parameters of the LEDs do not meet the established standards, a malfunction signal is issued to the control and monitoring device of the cross-country alarm system.

Using the proposed utility model allows you to:

1. significantly increase the efficiency of the crossing traffic light due to continuous direct control of luminosity, increase the reliability of the crossing signaling and reduce maintenance costs;

2. significantly improve traffic safety at level crossings, especially with high traffic intensity;

3. provide the ability to replace obsolete traffic lights with modern LED devices in accordance with the new requirements.
