The invention relates to regulating devices installed along the route of the trains or locomotives, namely, traffic signals, performing the functions of the indicator, permitting or prohibiting the movement of trains on station road.
Known traffic lights railway transport, in which the radiating element used single-strand filament lamp and reading light are changed by switching in the circuit contacts green and yellow alarm relay (rail Systems and is, 1996. - S. 68, Fig.4.1). Their disadvantage is the low reliability, due to frequent blown bulbs.
Higher reliability have lights that use double-filament incandescent lamp (Deev, A. M., Zenkovich Y. I., Kogan, D. A. and other resource-Saving technologies in the control devices reading lights // Automation, communication, computer science. - 2000. No. 1. - S. 32, Fig.1). However, the reliability is insufficient, because they fundamentally remains the use of incandescent lamps. In addition, the use of incandescent lamps defines high maintenance costs due to the need for periodic replacement of incandescent lamps. The efficiency of incandescent lamps, expressed by the ratio of the radiation intensity and cost of electrical energy, a small, which determines the low energy efficiency of these lights.
Closest to the proposed device is a traffic light, the energy efficiency is significantly higher than that of tube lights. It as emitting elements are LEDs led matrices (P Century. And., Etruscan A. E. Led for crossings traffic lights / Automatics, the light is here. This is due to the fact that to obtain, for example, three reading lights, you must have three structurally complete heads, each of which corresponds to one of its indication. In this respect, economically more favorable are projector lights that implement three readings of the lights in one head. However, the design of the internal mechanism of lights traffic light complex and has a low reliability.
The aim of the invention is the elimination of the lack of traffic lights that uses the led matrix by obtaining the possibility of implementing the three reading lights in one structurally complete head. This gives simplify both the structure and schema of the light that determines the reduction in the cost of manufacture and a reduction in operating expenses.
This goal is achieved by the fact that the light entered the second led circuit consisting of a serial connection included according To the led and resistor, the first output of which is connected to the first output of the first led circuit, connected to the second rear contact green signal relay, front contact of which is connected to Deut is i.i.d. with a common contact green signal relay, moreover, the first led circuit corresponds to the green indication light, and the second red. In the proposed device is the property of led elements having three color light when the scheme of the two LEDs (Earl F., Shits Century encyclopedia of electronic circuits. Tom. 7. Part 1.: TRANS. from English. - M.: DMK Press, 2001. - S. 276, Fig.31.11. or S. 290, Fig.31.30). In accordance with this leakage currents separately through the green and red LEDs give them radiation of the red and green colors. If you miss at the same time the current through the red and green LEDs, the resulting radiation will be yellow.
The drawing shows a diagram of a three-digit led light Device includes the first 1 and second 2 led circuits, each of which consists of a serial connection of LEDs 3.1,...3.To and resistor 4. General contact green signal relay 5 is connected with the common contact yellow alarm relay 6 and with one of the poles 7 of the power source, the other pole 8 which is connected to the first conclusions of the first 1 and second 2 led circuits. The second output of the first led circuit 1 is connected to the front contacts green 5 yellow 6 alarm relay and rear nanodiodes circuit 1 corresponds to the green indication light, and the second 2 - red.
Three-digit led light operates as follows.
The operation of the traffic light scheme is defined as a state of green contacts 5 and yellow 6 alarm relay. If both relays are off, the traffic light is red indication. When you enable yellow alarm relay the traffic light is yellow indication, and when the green signal relay, then the traffic light is green indication.
When the circuit common and the front contact 5 green signal relay to the first led circuit 1 are connected to the poles 7 and 8 of the power supply. Through the LEDs 3.1,...3.To the circuit 1 starts to leak current, causing them to glow. The amount of current depends on the resistance of the resistor 4. Physical and technological parameters of LEDs 3.1,...3.To chain 1 define them glow green. That is, when a voltage is applied to the first led circuit 1 a three-digit traffic light is green indication.
If the green and yellow signal relays are in the off state, in General and rear contacts 5 green alarm relay power supply is connected to the second led circuit 2. Through the LEDs 3.1,...3.To and resistor 4 circuit 2 starts protest. Therefore, when the off state green and yellow alarm relay the traffic light is red indication.
When off the green signal relays and switched on the yellow alarm relay through closed contact 6 yellow alarm relay and through General and rear contacts 5 green alarm relay current flows in the first led circuit 1 and the second 2. The summation of the spectra of their radiation in one structurally complete led matrix determines a yellow led that produces a yellow indication light.
In the General case, in the scheme of the traffic light as the first 1 and second 2 led circuits can be used parallel connection of several similar led groups.
Thus, the invention uses only two types of led circuits having two color light: green and red, but the result of the operation of the device provides three color light: green, red and yellow.
Therefore, the use of the proposed device allows you to have constructively only one head for the three reading lights. This determines the possibility of reducing the cost of the traffic light, simplify operation and reduce ekspluatacii contacts green and yellow alarm relay and the first and second led circuit different color light, consisting of a serial connection included according To the led and resistor, where General contact green signal relay is connected to one of the poles of the power source, the other pole of which is connected to the first findings led circuits, characterized in that the second output of the first led circuit is connected to the rear contact green signal relay, front contact of which is connected to the second output of the second led chain and front contact yellow alarm relay common contact connected to the common contact green signal relay.
