(54)	Electronic gas-lighter with ignition spark to be fed by a battery rechargeable by a solar cell

(57) The standing of the gas-lighter in a luminous room determines the picking up of the light with direct conversion in electric energy by means of a solar cell (1) that on line (2) sends said energy to a battery (3) putting into effect the recharge continually. Said energy on line (4) by a swithc (5) puts in action on line (6) an oscillator (7) while on line (8) puts in action a transistor (9) connects to a resistance (11). The oscillator (7) gives energy to the diode (15) which transfers the same to a capacitor (17) from which a transformer (19) is fed. Contemporary from diode (15) an energy part is transfered to a resistance (21) from which the same comes to a silicon controlled rectifier (23), the operating of which is regulated by a resistance (25). The energy of the transformer (19) is increased from a capacitor (31). The resulting energy is given available to the transformer (19) on line (35) which determines an electric art toward the line (27) generating a repetitive ignition stark.
