Abstract

DC60 This invention presents a battery charging and lighting control circuit. While not charging, the 7-1 DC converter, even when initially set up, the half-wave element Wp remains OFF. The voltage of the half-wave element Wp is a waveform approaching the positive side when there is no load. Voltage sensing circuit 801 detects the voltage of the half-wave element Wp. The crossover circuit 803 applies a voltage drop only at the relative crossover voltage of the detected waveform to the charging voltage Vc. The collector circuit 804 outputs the collected power for a time delay Vt. The channel control circuit 805, based on the time delay from the start of the negative half-wave element Wn, turns the 7-2 DC converter ON with the delayed time. The resulting delay time Td, compared to the area of excess current flowing out to the lamp side 6, is initially set up. For standard current flow during charging, the maximum current flow during non-charging can be adjusted to an equal average value. This invention presents a battery charging and lamp switching control circuit. While not charging, the converter 7-1, even when initially set up, the half-wave element Wp remains OFF. The voltage of the half-wave element Wp is a waveform approaching the positive part under no load. Voltage detection circuit 801 detects the voltage of the half-wave element Wp. The crossover circuit 803 reduces only the crossover voltage relative to the detected waveform with respect to the charging voltage Vc. The collector circuit 804 outputs the collected power for displaying the delay time Vt. The channel control circuit 805, based on the display of the delay time from the start of the negative half-wave element Wn, turns the converter 7-2 ON with the delay time. The resulting delay time Td, compared to the area of excess current, allows for the output current to flow to the initial 6-lamp side. For standard power output current during charging, adjusting the maximum output current while not charging can be averaged to achieve similar values.
