ABSTRACT:
Disclosed is a solar powered lamp adopting a cold-cathode fluorescent lamp and an auxiliary startup device which can improve the efficiency of the voltaic-photo transformation when lighting the cold-cathode fluorescent lamp. The device comprises a direct current power unit, a DC/AC inverter circuit for generating a high voltage alternating current from the DC voltage to light a CCFL; and an auxiliary startup circuit disposed between the DC power supply unit and the DC/AC inverter circuit for generating across the input terminals of the DC/AC inverter circuit a voltage of about twice of the DC voltage output from the DC power supply unit.
