FIG. 1- structural diagram;

FIG. 2- control device and control | signal of traffic lights (general view);

FIG. 3- circuit diagrams of stabilization blocks for voltage supply and LED emitters.

YcTpoilcTBO contains a signal light unit 1, the outputs of which are connected to transceiver blocks 2, 3, consisting of half-sets of a cyclical telemechanics system connected by a communication channel, green 4, yellow 5, red 6 traffic light connection blocks, to the outputs of which are connected their respective series-connected the health monitoring units of the LED emitters 7, 8, 9, stabilization power supply modules 10, 11, 12, made in the form of an electronic circuit located on a printed circuit board 13, one of the inputs of which is connected Directly with the outputs of the corresponding connection blocks 4, 5, b, and other inputs are connected to the connection blocks 4, 5, 6 through control units 7, 8, 9, the outputs of the voltage stabilization blocks | 0, 11, 12 are connected to the corresponding inputs of the blocks LED emitters of green 14, yellow 15, red 16 of the glow color, made in the form of an electronic circuit located on the printed circuit board 17 with LEDs 18, mounted in the grooves of the housing 19 (for each glow color).

The printed circuit board 13 of the voltage stabilization unit (for example 10) (Fig. 3) contains the following electronic components: rectifier diodes VD1 - VD4, filter capacitors C1, C2, supply voltage stabilizer chip DD1, voltage comparator DD2, resistors R1-R9, R 14, R15, a key element in the transistor VT1.

The operation of the power supply voltage stabilization unit is as follows (diagram in Fig. 3)

The rectifier VD1-4 and the filter capacitor C1 form a smoothed DC voltage at their outputs. Next, this voltage is fed to the input of the voltage stabilizer DDI, at the output of which the voltage with the value necessary to obtain the given lighting characteristics of the LED emitter is selected by resistor R2.

The comparator is based on the DD2 microcircuit and measures the current in the power supply circuit of the LED emitter and, if it is less than the threshold value, the comparator disconnects the LED emitter from the voltage source using the transistor VT1, which eliminates the need to highlight the LED emitter caused by noise induced in the communication lines, t since the induced currents are less than the threshold value set on the comparator.

The device can operate both on direct and alternating current.
