HALOGEN MODIFICATION OF LIGHTING DEVICE BASED ON LED (LIGHT-EMITTING DIODES) USING ELECTRONIC TRANSFORMER AND CONTROLLER

摘要

FIELD: lighting.;SUBSTANCE: control circuits (1) lead the power converters (4) to different modes in response to the detection results. Power converters (4) exchange possible straightened first current/voltage signals with electronic halogen transformers (2) and the second current/voltage signals on the circuit of light-emitting diodes (5). The first current signals have different amplitudes for different modes. Different amplitudes have different constant values and/or different values of the derivatives. As a result, the first current signal becomes a relatively volatile first current signal. Then the halogen transformers (2) will no longer experience the problems that arise when it is necessary to provide smaller amounts of power than designed. The detection may comprise detecting polarity and/or detecting transitions through zero in the first voltage signals. Halogen transformers (2) contain power supplies with self-oscillating switchable mode, designed to provide the first quantities of power at their outputs. The circuits of the light-emitting diodes (5) are designed to consume second power amounts less than the first quantities.;EFFECT: improve the operation of the device.;19 cl, 12 dwg
