Lianchuang Optoelectronics: LED chip prices rose once and rose

This year's LED industry can be described as hot. The hottest ones are upstream equipment, raw material suppliers, and mid-stream chip makers! From looking around for customers to picking customers, borrowing money from four to buy equipment, and queuing for venture capital, the LED lighting industry is booming. The market expects.

In order to seize the commanding heights of the LED lighting industry, governments have introduced policies to support them. Under the pressure of energy conservation and emission reduction and economic restructuring, China is planning to accelerate the development of emerging industries such as LED.

The LED concept stock Lianchuang Optoelectronics (600363), which was listed as a major shareholder, was once sealed on the daily limit.

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.
