The reporter learned from Osram yesterday that in order to build a sustainable low-carbon World Expo, OSRAM and its parent company, Siemens Group, provided green lighting technology support for more than 40 projects of the Expo. In particular, the LED lights that were commissioned in six months accurately interpreted the Chinese pavilion as the fascinating color of the "Forbidden City Red." Compared to conventional halogen lamps, OSRAM LED lamps can save more than 70% of electricity; and OSRAM's various lighting systems used in the Expo Center can achieve energy efficiency of up to 33% compared to conventional lighting solutions.
Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
