L light source uses outdoor lamp with lithium ion capacitor

L light source company launched a lithium ion capacitor used as a storage device lighting Small Capacity". Equipped with a small solar cell, which can store electricity generated during the day. Lithium ion capacitor using ACT (Advanced Capacitor Technologies), "Premlis A5000" (electrostatic capacity of 5000F, unit volume energy density of 25Wh/kg). Equipped with 2 Premlis with 16.6Wh storage capacity. The internal resistance of the capacitor is less than 5m, which can be used in the storage of the weak light when the lead-acid battery can not store electricity. In addition, due to the characteristics of charge and discharge cycle is good, can be used for more than 10 years.

The Small Capacity is designed to be used in places where there is no need for higher brightness, such as no street lights. Equipped with a power consumption of 2W high output LED. 6 kinds of lighting modes can be switched automatically, thereby reducing the power consumption, for example, will use a dinner on the setting of electric power is about 6Wh, or to reduce the brightness in less storage capacity. In this way, even if the use of smaller capacitors, do not need to worry about the battery, etc., can be used for about a year. The price for sale stores vary, not including construction costs about 500 thousand yen. 09 years before and after May will also be listed near the sensor model.
