The invention relates to electric lighting devices, namely the scheme of the device for powering the light sources, not classified in other subclasses.

Known schemes of devices for supply of light sources made with LEDs containing a group of LEDs, the formation through which currents are controlled using active resistors (Davidenko, Y. N. Modern circuitry in the lighting. SPb.: Science and technology, 2008. - P. 233, Fig.4.25). The disadvantage of such devices is the low energy efficiency due to significant losses power dissipated in the active resistors.

More energy-efficient devices are radiation, in which the formation of the current through series-connected LEDs are controlled using drivers containing the LC filter based on the use of pulsed methods of regulating current (Davidenko, Y. N. Modern circuitry in the lighting. - SPb.: Science and technology, 2008. - P. 243, Fig.5.11). The disadvantage of this device is its low reliability, because if you experience breakage in one of the led's radiation disappears in the whole group of series-connected LEDs.

The closest to the proposed device is an led emitter, which has the power of every led ceiling lamp with LON�s is provided by a separate driver (Davidenko, Y. N. Modern circuitry in the lighting. SPb.: Science and technology, 2008. - P. 242, Fig.5.7).

The disadvantage of such devices is the high cost of led emitter due to the need of application of a significant amount of drivers, each of which must control your led.

The aim of the invention is to improve the reliability of led emitter and a decrease in its value.

This object is achieved in that in the scheme of led emitter entered the keys and the ring pulse generator that allows to reduce the number of drivers to one.

The invention consists in that in the scheme of led emitter entered N keys and the ring pulse generator having N outputs, each of which is connected to the control inputs of the keys, and the cathodes of each of the N LEDs through the power electrodes of keys connected to a negative pole output driver.

The figure shows a diagram of the led emitter, including the driver 1, the inputs are connected to a power source (EpN LEDs 2.1, 2.2, 2....N, the ring pulse generator 3, and N keys 4.1, 4.2,..., 4N. Positive pole output driver 1 is connected to the anodes of the LEDs 2.1, 2.2, 2....N. The cathodes of each of 2.1, 2.2, 2....N LEDs through the power electrodes of keys 4.1, 4.2, 4....N are respectively connected � negative pole output driver 1. Control inputs of the keys 4.1, 4.2, 4....N are connected to the outputs of the ring oscillator pulses 3.

Led emitter works as follows.

Ring pulse generator 3 produces at its outputs a sequence of pulses that when applying to the inputs of keys 4.1, 4.2, 4....N causes a cascade and sequential in time of their inclusion. The presence of the output voltage of the driver 1 and the sequence of pulses generated by the ring pulse generator 3 that controls the operation of the keys 4.1, 4.2, 4....N, causes successive emission of each led 2.1, 2.2, 2....N. A sufficiently high repetition rate of the output pulses of the generator 3 will determine perceived by the human eye radiation LEDs 2.1, 2.2, 2....N as continuous.

As keys 4.1, 4.2, 4....N can be used transistors, implemented in bipolar or MOS semiconductor structures.

If you experience breakage in one or a few LEDs 2.1, 2.2, 2....N others will continue to radiate that will provide permanent work led light source.

Thus, the use of keys 4.1, 4.2, 4....N and o-pulse generator 3 delivers reliable performance of the proposed led light source when using only one driver that will significantly reduce its value�you.

Led emitter containing N LEDs and driver control, the positive output pole of which is connected to the anodes of the LEDs, characterized in that in the scheme of led emitter entered N keys and the ring pulse generator having N outputs, each of which is connected to the control inputs of the keys, and the cathodes of each of the N LEDs through the power electrodes of keys connected to a negative pole output driver.
