Abstract: The invention relates to electric lighting facilities powered from an external electrical network. The light-emitting diode lamp comprises a step-down voltage converter (1) made up of a chain of capacitors (2, 3, 4) connected in series, one of which is a power take-off capacitor (3) and is connected to at least one pair (5) of inverse-parallel connected light-emitting diodes (6, 7). The invention makes it possible to achieve extremely low electrical energy consumption for lighting, ensure optimum performance, and use the circuit for the additional function of supplying power to external users of, for example, mobile telephones.

Abstract: The invention relates to light sources having an ultra-low active-energy consumption. The LED lamp of the present invention includes a voltage down-converter (1) in the form of two capacitors (2, 3), one of which is a power bleed capacitor, and at least one pair of light diodes connected back-to-back and in parallel (5, 6). According to the invention, in order to reduce the reactive current in the supply circuit, an induction (8) is coupled in series with the light diodes (5, 6) and defines an electric oscillating circuit (9) together with the power bleed capacitor (3) according to one variant of the invention, and together with the output capacitor (11) and the light diodes (5, 6) according to another variant.
