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.
Claims6
A light-emitting diode lamp, comprising:
- one or more pairs of light-emitting diodes;
- said light-emitting diodes of each said pair of light-emitting diodes being connected in parallel and in opposition to each other;
- a voltage down-converter electrically connected with said light-emitting diodes and used to maintain a power supply level of said light-emitting diodes;
- said voltage down-converter comprising a first capacitor, a second capacitor, and a third capacitor;
- said first, second and third capacitors being directly connected to each other;
- said first, second and third capacitors being connected in series to each other;
- said second capacitor functioning as a power take-off capacitor;
- a first terminal of said light-emitting diodes being electrically connected directed to a first junction of said first and second capacitors;
- and
- a second terminal of said light-emitting diodes being electrically connected directed to a second junction of said second and third capacitors.
