To provide a power storage system which can endure preservation for a long time, and in which deterioration due to repeated charges and discharges is small and inexpensive.

In this illumination lamp equipped with receiving function, a power storage unit is mounted that has a long life with a large electric capacity to store day-time electricity from a solar cell, and consumption of electric power is reduced as much as possible while an information receiving function is given at the same time, and the lamp is lighted at night in the case of a disaster. A white screen panel such as a liquid crystal television or the like is used as the lamp, and an electric double layer capacitor is used as a power source for charge and discharge in order to have sufficient discharge capacity. Since it can be used as a night-light in a bedroom or the like or as an amusement television at a normal time, it is more worthwhile to be kept as a ready service stock.
