<p>A lighting device with a compact structure, of the type comprising a light source of the fluorescent type (12) coupled with a light source of the incandescent or halogen type (13), having an adequate power, so as to obtain a twofold contribution in immediately reaching the emission of a satisfactory light flow; once the nominal flow has been reached, an electronic circuit interrupts the power supply to the incandescent or halogen light source (13), so that the current absorptions and light flow are those characteristic of the fluorescent light source (12). In practice, the lighting device according to the invention allows optimum lighting levels to be reached immediately (typical characteristic of an incandescent light source), at the same time with a reduced consumption, a considerable energy saving and long functioning life (typical characteristics of a fluorescent light source).</p> |
