Hefei will build LED (Light Emitting Diode) Industrial Park

The LED Industry Park project special investment promotion conference was held in Shenzhen. Provincial and municipal leaders Sun Jinlong, Wu Cunrong, Wang Linjian and the responsible persons of Gaoxin District and Xiangyang District, including the heads of 12 companies including Shenzhen Fu Shi Yuan Landscape Engineering Co., Ltd., attended the promotion meeting.
LED is the abbreviation of Light emitting diode ,, which refers to a cold light source made by a new material technology. Compared with traditional incandescent and fluorescent light sources, the main advantages of this light source are energy saving, environmental protection and long life. aspect. It is reported that the LED Industrial Park, which is planned to be located in the Xiangyang Industrial Park, will be built with a investment of several hundred million yuan in 3-5 years. The first phase will be to build a LED industry R&D and landscape lighting package base, with an investment of 50 million yuan. It is put into production this year.

Low temperature lithium battery refers to the working temperature under - 20 ℃,to meet different environment and temperature. YFJ company has designed a lot of this kind of Low Temperature Battery with our own advantages.

1.Dual IC chips, that can anti-shortcircuit, anti-overcharger, anti-overcurrent, anti-overload

2.Widely using temperature range, lower temperature Lithium Battery can be operated in -50°C~+60°C

3.Long cycle life, more than 500 charge/discharge cycles (0.2C)( 80% capacity remained ). more than 800 times(0.1C charge/discharge
4.The Battery Pack has a high cycle life, which conforms to the values of low carbon, energy saving and environmental protection
