Nickel-cadmium storage batteries and lead-acid batteries used in emergency lighting equipment are generally designed to exhibit maximum efficiency at ambient temperatures of 10°C to 30°C, and chemical reactions do not occur in low-temperature environments below 0°C. As the battery becomes more active and the battery capacity decreases significantly, the
Conventional emergency lighting equipment with built-in storage batteries could not be used in cold storage warehouses, etc., which are exposed to low-temperature environments ranging from -40°C to -40°C.

Fig. 1 is a circuit diagram showing an embodiment of the lighting equipment of this invention.
A charging device 2 is connected to this power source and supplies charging current to the built-in emergency lighting power source battery 3. During normal times, this charging device 2 charges the battery 3 using a built-in charging circuit (not shown), but during a power outage, a built-in charge/discharge switching relay (not shown) is used to charge the battery 3. The battery 3 is discharged and, for example, an incandescent light bulb 4 is turned on. A heater 5 surrounds the built-in battery 3 and is constantly heated by the AC power source 1.

である。 By the way, this heater needs to maintain a uniform temperature around the outer circumference of the battery 3, so for example, a linear heater made of nichrome wire covered with silicone rubber or a planar heater made of a thermistor covered with ceramic or the like is used. . In addition, the built-in battery 3
As shown in Figure 2, the charging efficiency is highest at an ambient temperature of 10°C to 30°C, and a thermal switch 6 is built into the heater 5 to maintain the temperature within this temperature range. There is. 7 is a connector that electrically connects the battery 3 and the charging device 2.

As described above, the lighting equipment of this invention surrounds the built-in emergency lighting power battery with a heater.
Moreover, since this battery is maintained at a predetermined constant temperature state by the function of a thermal switch, the charging efficiency of the battery can be improved even in low-temperature environments such as cold storage warehouses where the temperature is constantly between -20℃ and -40℃. It can be used as a power source battery for emergency lighting of emergency lighting equipment in a good state of charge at all times without deterioration.
