- an LED light source comprising a rectifier diode bridge, to the output of which LEDs are connected, in series with which a current regulator comprising a voltage regulator is connected, the output of which is connected to the first output of the resistor, the second output of which is the output of the current stabilizer and connected to the control the input of said voltage stabilizer, while the LEDs are interconnected in series.
- RU 79741 U1 contains a step-down voltage converter, which is connected through at least one LED through a rectifier diode bridge, and a capacitive filter is connected in parallel with the rectifier diode bridge and LED.
- a step-down voltage converter is made of a series of series-connected capacitors, at least one of which, being a power take-off capacitor, is connected to a rectifier diode bridge.
- the objective of the utility model is to increase the stability and reliability of the LED light source in transient conditions.
- an LED light source containing a step-down voltage converter, which is connected through at least one LED through a rectifier diode bridge, and a capacitive filter is connected in parallel with the rectifier diode bridge and LED, and the step-down voltage converter is made of a series of capacitors connected in series .
- a rectifier diode bridge is connected to break a chain of series-connected capacitors of a voltage converter.
- a quenching resistor with a nominal resistance of several hundred ohms to units of megohms is connected in parallel with the capacitor in the capacitive filter.
- a thermistor with a negative resistance coefficient with a nominal resistance of several tens of ohms to hundreds of ohms can be sequentially connected to the circuit.

- a current-limiting resistor with a nominal resistance of several ohms to hundreds of ohms is connected in series to each branch of the capacitor circuit.
- the figure shows a circuit diagram of an LED light source according to the present utility model.
- the LED light source comprises a step-down voltage converter A, a rectifier B, a filter C, a block D of LEDs that are electrically connected to each other.
- the step-down voltage converter A contains a series of capacitors connected in series 5.

- the voltage limiter 2 limits the amplitude of the voltage jumps in the supply network to no more than the permissible value (as a rule, 1.2 - 1 5 times higher than the rated value of the mains voltage).
- the reduced voltage from the voltage converter A is supplied to the input of the rectifier diode bridge 7, and the direct current from its output through the thermistor 8 energizes the LEDs 1 1.
- the resistance of the thermistor 8 is hundreds of ohms, and as it heats it decreases to units of ohms , then the supply voltage of the LEDs 1 1 gradually increases, they flash and, gradually kindling, illuminate the surrounding space.
- the discharge resistors 3, 4 and 6 the charge accumulated in the capacitors of the circuit is removed after turning off the LED light source.
- the capacitor 9 provides smoothing of the ripples of the rectified current, and the quenching resistor 10 provides an effective discharge of the charge of the capacitor 9 after turning off the circuit, which ensures sharp damping of the LEDs 1 1.
- the LED light source becomes resistant to sharp voltage fluctuations in the supply network, and its reliability is improved during repeated switching on and off.
