The substrate 3 is arranged so as to penetrate through the mounting portion 1 and the housing 2, and the substrate 3 is arranged along the axis from the housing 2 to the inside of the mounting portion 1. A solar cell (solar panel) 4, an LED light emitter 5, and a reflector 6 are arranged inside the wall surface in this order from above to below in the housing 2 portion of the substrate 3, and the mounting portion 1 of the substrate 3 is arranged. A secondary battery 7 such as a nickel hydrogen battery that stores the power generated by the solar cell 4 in a portion, and the LED light emitter 5 is lit by a switch 9 using the power stored in the secondary battery 7. It is a configuration in which a lighting control circuit 8 for blinking is housed.

Then, as shown in FIG. 15, for example, the conventional safety light L having the above configuration is used by being detachably attached to a road safety member S such as a triangular cone or construction equipment installed on the road, and is determined in advance. When the darkness becomes predetermined, the lighting control circuit 8 switches from the state of being charged by the solar battery 4 in the daytime to lighting or blinking the LED light emitter 5 by the power from the secondary battery 7. In particular, since this type of safety light L is covered by the power generated by the safety light itself during the daytime by the solar battery 4 in which the secondary battery 7 is housed in the housing 2, when an AC power source is used. Compared to this, it is functionally superior and does not require the trouble of battery replacement as in the case of using a primary battery, and is economically excellent.

By the way, the safety light L is designed by determining the capacities of the solar cell 4, the LED light emitter 5, the secondary battery 7, etc. in consideration of the ratio of the time during the daytime and the time at night throughout the year, but it is actually used. At that time, for example, if the battery is used in a place with little sunshine such as a snowy country or if bad weather continues, or if the installation location is shaded and the sunlight is bad, the charge amount will be insufficient and the charge amount will be low during the daytime charging time. There is a problem that it may not be possible to light a light emitting body such as an LED when it should be turned on due to a shortage.

Therefore, Japanese Patent Application Laid-Open No. 2017-4097 describes a solar cell, a secondary battery for storing electric power converted from optical energy by the solar cell, and a dry battery accommodating portion, and the voltage of the secondary battery is equal to or higher than a predetermined value. In this case, the charging unit supplies power to the part of the construction light that requires power, while when the voltage of the charging unit is lower than the predetermined value, the portion that requires power from the dry battery Security lights (construction lights) that supply electricity have been proposed.

However, when a dry battery is used as a power source, there is a problem that the dry battery is consumed quickly, and the labor and cost for replacing the dry battery increases (usually, it is necessary to install a large number of construction lights of this type). As a whole, the labor and cost required for replacing the dry battery is enormous), and there is a problem that the sealing property is impaired due to the replacement of the battery.
