| description | In the present invention, there is disclosed a system for electronic control of light emitting diodes (LED) intended particularly for visual signaling in railway traffic, comprising at least one column (SLi1 through SLik) of light emitting diodes (LEDs) with additional circuits. The system alternating or direct current voltage input is connected to a measuring circuit (MOUI) of input voltage and current wherein said measuring circuit (MOUI) output is connected to the block of a boosting converter (ZM) comprising a pulse generator (GI) and a switch (SP). The outputs of the input voltage and current measuring circuit (MOUI) are connected respectively to a first and a second control blocks (CPUiA, CPUiB), which are connected with each another, are independent of each another and are individually connected to a first and a second blocks (BSiA, BSiB) of a safe passage of an exciting signal of the switch (SP). These blocks (BSiA, BSiB) of the safe passage of the switch (SP) exciting signal are connected in series between the pulse generator (GI) output and the switch (SP). Both a measuring circuit (MOUC) of said boosting converter (ZM) output voltage and at least one column (SLi1 through SLik) of light emitting diodes (LEDs) with additional circuits are connected to said boosting converter (ZM) block output . The outputs of the boosting converter (ZM) output voltage measuring circuit (MOUC) are individually connected to the first and second control blocks (CPUiA, CPUiB). Each column (SLi1 through SLik) of the light emitting diodes (LED) comprises series connected LEDs that are series connected with a LEDs current source (PZ) and a current measuring circuit (MOI) and further with a voltage measuring circuit (MOU) to a series combination of the current source (PZ) of both the LEDs and the current measuring circuit (MOI). The outputs of the current measuring circuit (MOI) and the outputs of the voltage measuring circuit (MOU) of the series combination of the LEDs current source (PZ) and the current measuring circuit (MOI) are individually connected to the first and second control blocks (CPUiA, CPUiB) for its control to the first control block (CPUiA) and/or the second control block (CPUiB), whereby the input of the LEDs current source is connected to the second control block (CPUiB) while the first control block (CPUiA) is connected to a coding circuit (KO). |
