The present invention belongs to the technical field of solar lamps, and more particularly relates to a double battery switched dual-purpose solar lamp.
It is well-known that a solar lamp consists of a photovoltaic battery, a secondary rechargeable storage battery, a control electronic circuit board, light sources and other structure components. During the daytime, a solar photovoltaic battery converts solar energy into electric energy to charge the secondary storage battery, and at night, the secondary rechargeable storage battery supplies power to the light sources through the control circuit board such that the light sources light. Such product which takes the solar photovoltaic battery slice as a unique power supply source has a certain performance defects, i.e., a site of use fails to gain sufficient light during the bad weather (rainy or cloudy) or when the use conditions of a user are limited, the solar photovoltaic battery slice cannot store sufficient electric energy for the secondary storage battery during the daytime to maintain the lighting time at night, and therefore, the adaptability and the user experience of the lamp are greatly reduced.
To solve the technical problem that the normal lighting time cannot be maintained by light sources at night because an existing solar lamp just takes a solar photovoltaic battery slice as a power supply source and the solar photovoltaic battery slice cannot supply sufficient electric energy to a secondary storage battery during the bad weather or when the site of use cannot be gain sufficient light, the present invention provides a double battery switched dual-purpose solar lamp.

The LED light sources 6 are connected with the control circuit board 7 through plug-in pieces and wires.
The control circuit board 7 comprises a second battery charging and discharging control part 71, a second battery capacity detection part 72, a first battery discharging control part 73 and a light source lighting timing control part 74, wherein the second battery charging and discharging control part 71, the second battery capacity detection part 72 and the first battery discharging control part 73 are connected in sequence; the solar photovoltaic battery slice 3 and the second battery 241 are connected with the second battery charging and discharging control part 71, the second battery discharging and discharging control part 71, the light source lighting timing control part 74 and the LED light sources 6 are connected in sequence, and the first battery 231, the first battery discharging control part 73, the light source lighting timing control part 74 and the LED light sources 6 are connected in sequence.
During the daytime, the solar photovoltaic battery slice 3 converts solar energy into electric energy and transmits the electric energy to the second battery 241 through the second battery charging and discharging control part 71, and the second battery 241 stores the electric energy.
At night, when the solar photovoltaic battery slice 3 detects that the illumination drops to a lighting threshold (0-500LUX), the second battery charging and discharging control part 71 is connected to the second battery 241, the second battery 241 supplies power to the LED light sources 6, the light source lighting control part 74 works, the LED light sources 6 light, and then the LED light sources 6 are automatically powered off after 6 or 8h from the beginning of lighting.
