Abstract
The device includes a photovoltaic panel, an illumination lamp, a control device and a lamp strap disposed on the photovoltaic panel; the photovoltaic panel is electrically connected to the control device, and when the photovoltaic panel senses light, the photovoltaic panel performs photoelectric conversion and generates a conversion electric signal, so as to output the conversion electric signal to the control device; the control device is electrically connected to the lamp strap, and when the voltage of the conversion electric signal is lower than a preset threshold, the control device generates a driving electric signal, so as to transmit the driving electric signal to the lamp strap; the control device is electrically connected to the illumination lamp, and the control device transmits an illumination signal to the illumination lamp for illumination; the lamp strap receives the driving electric signal, and emits light.
