Description

The utility model relates to the field of lighting engineering, namely, to the designs of lighting devices and can be used, for example, in various signaling devices (automobile and railway traffic lights, coastal river and sea signs, airfield lights, etc.) to ensure traffic safety funds.

The closest known solution to the technical nature and the achieved result from its use to the claimed solution is the design of a railway traffic light system according to the RF Certificate No. 27313 for utility model, B61L 5/18, 2002, containing a glass lens on which a light source mounted in in the form of a matrix of LEDs with a given glow color, located on a printed circuit board and connected to a power source and a housing that covers the back of the glass lens, which contains elements of protection against power surges.

The task to which the claimed utility model is directed is to expand the scope, increase traffic safety, increase service life and reduce operating costs.

The problem is solved, first of all, using the technical result obtained from the use of the claimed utility model, which consists in improving the lighting parameters, the use of highly reliable light sources, in the presence of continuous monitoring of the emitted light flux, continuous diagnostics of the system’s operability, including communication lines and power lines .

In the field of railway applications, the Integrated Microprocessor-based System of LED Traffic Light Alarm (KMSS) is designed to work in areas equipped with a microprocessor-based signal management system ECEM, MPCI, MPC-2, Bombardier, Siemens, Dialog, etc.

The basic element of the KMSS is a light-emitting diode optical system (CCC) with LED light control and digital control.

The specified technical result is achieved by the fact that in a known lighting device, a light source is installed, made in the form of a matrix of LEDs with a given glow color, located on a printed circuit board and connected to a power source. Each LED has an individual radiation driver, and each LED corresponds to an individual current source and a device for recording light flux. The communication with the fire control system is carried out via a digital line, which informs the microprocessor control system of the state of fire. The transition to any operating mode is carried out only at the command of the microprocessor signal control system.

Different sections of the protective polymer glass have a slope relative to the vertical axis to reflect the incident light from external sources of light down and to prevent reflected light from entering the driver’s eyes.

The special implementation of some of the basic structural elements of the LED light-optical system can significantly increase the efficiency of its operation and, accordingly, the safety of vehicles on the traffic routes, on which signal devices based on the KMSS will be installed.

The inventive utility model is illustrated in figure 1, which shows a variant of the LED light-optical system included in the integrated microprocessor system of LED traffic lights and intended for use in a railway mast traffic light.

The design of the proposed model contains glass, on which a group lens is fixed, a light source made in the form of a matrix of LEDs with a given glow color, located on a printed circuit board and connected to power sources and a housing in which electronic control and control modules are located.

The proposed KMSS operates as follows. When the traffic light operates in the daytime in bright sunlight, after turning on the LEDs, the light rays freely pass towards the observer (not shown in the figure) to which they are intended. Loss of light flux during the passage of the protective glass is insignificant (the experiments showed that the loss in the protective glass is no more than 15% of the total energy of the light flux from the light source). At the same time, the sun's rays that hit the front inclined surface of the CCC protective glass are reflected downwards and do not fall into the eyes of the observer.

The electrical circuit of the KMSS is made on a modular basis. The role of the security element is played by an internal controller, the software of which allows you to control the operating modes of the LEDs, continuously monitor the health of all KMSS nodes including communication lines and communicate with the control microprocessor system according to the RS 485 standard. Since the microprocessor signal control system communicates with the KMSS via a digital line, this interface device does not contain a single relay, unlike the control of traffic lights on incandescent lamps.

Using the proposed utility model allows you to:

1. Significantly increase the efficiency of the lighting device by increasing the reliability of its work and reduce operating costs.

2. Significantly improve the operational safety of various traffic streams: river and sea routes, roads and railways, as well as subway lines.

3. To provide the possibility of replacing obsolete heads of mast traffic lights on incandescent lamps with modern LED devices with a higher level of security.

4. Simplify the design of the mast traffic light while reducing its size and weight.

5. To provide broader functional capabilities of traffic lights (fixing the precautionary state of the signal light, transmitting additional information from the microprocessor-based signal control system through the KMSS through the light beam to the receiving devices of the rolling stock).
