Abstract

The invention is suitable for the lighting technical field and provides a light emitting diode (LED) drive circuit, an LED luminaire and an LED lighting system. The lighting system comprises a ballast and the LED luminaire connected with the ballast, wherein the LED luminaire contains a plurality of LED lamps; and the LED luminaire also contains the LED drive circuit which are separately connected with the ballast and the LED lamps. In the LED lighting system of the invention, the power storage element of the LED drive circuit and the inductor of the ballast form a loop to generate the exciting current and ensure that the normal operation of the oscillating circuit of the ballast can be maintained. Therefore, when the ballast is used to drive LED lamps with low power, the ballast can not be in an intermittent state or a complete stop state so that the operation state of the LED lighting system is very stable.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED driving circuit, an LED lamp and an LED lighting system. Background technique [0002] A traditional lighting system usually includes a ballast and a lamp driven by the ballast. The ballast converts the mains 220V alternating current into a low-voltage alternating current, which is then used to light the lamp. [0003] With the emergence of LED lamps, LED lamps have the advantages of high luminous efficiency, so LED lamps have gradually replaced traditional lamps, figure 1 The structure of an existing LED lighting system is shown, which includes a ballast 10 and an LED lamp 20 , and the LED lamp 20 further includes an LED driving circuit 21 and an LED lamp 22 . [0004] However, compared with traditional lamps, the power of the LED lamp 20 is smaller, and the ballast 10 works according to the oscillation of its internal oscillating circuit, and the oscillatin...
