LIGHTING UNIT Russian patent published in 2005 - IPC

FIELD: autonomous light sources.

SUBSTANCE: device can be used as autonomous transformer-free type light radiation source being able to work as fed by an ac general circuit power supplies and by dc supply (on-board automobile circuit) and solar batteries having small surfaces to be illuminated. Device has photo-electric converter and storage batteries and light source connected to each other by corresponding contacts of switch. Device also has pulse step-up voltage regulator which has input connected with photoelectric converter. Output of voltage regulator is connected to charge current pulse former. Output of pulse former is connected with corresponding terminal of the converter mentioned above which intends for providing supply of charge current to storage battery. According to the other version of the realized device, output of voltage regulator is connected with current adder through charge current voltage regulator to provide connection of the adder to storage battery through mentioned switch.

EFFECT: reduced cost of electric lamp; simplified exploitation.
