Fig. 8 is an external view of a single-sided light storage plate 31. Because the energy consumption of the LED light source module 4 is reduced, the capacity of a battery arranged in the light storage plate is also reduced, and the required photovoltaic plate can be reduced to be less than 20% of the area of the whole light storage plate, so that the photovoltaic plate 11 and the light emitting surface 2 can be arranged on the same plane, and the normal light emitting of the light emitting surface 2 is not shielded.
