LIGHTING DEVICE Russian patent published in 2018 - IPC H05B33/08 

FIELD: lighting.

SUBSTANCE: lightning device has at least one contact into which the illuminant can be inserted. Lighting device has an electric or electronic ballast, through which the required supply voltage for fluorescent lamps or incandescent lamps is guaranteed. Ballast can be used for a set of series-connected LEDs of led lighting, wherein current set of light-emitting diodes are essentially corresponding to the lamp current during operation of lighting devices with fluorescent lamp. As a protective circuit (33) thyristor clamping chain is made in the led lighting device (4), wherein bridge rectifier (32) has four diodes, which are regulated on their reverse recovery time, relatively the switching frequency of the ballast (20), wherein the lighting device (2) is made flameproof.

EFFECT: improvement of lighting devices to enable simple substitution between, for example, fluorescent lamp and led lighting means od a set of light-emitting diodes without having electrical or mechanical adjustments of lighting devices.
