On March 1st, Hurun Research Institute released the "2018 Hurun Global Rich List". According to the list, Amazon founder Jeff Bezos became the world's richest man with 775 billion yuan of wealth. Buffett surpassed Bill Gates. Second, Ma Huateng became the richest man in China and ranked 15th in the world.
2018 Hurun Rich List, the world's top ten richest
It is understood that there are 819 billion-dollar billionaires in Greater China, ahead of the 571 in the United States. It is worth mentioning that there are many familiar LED industry giants on the rich list. Sanan Optoelectronics Lin Xiucheng, Lin Zhiqiang and his son ranked 329th with 39 billion yuan, and the wealth value increased by 68% year-on-year.
Among them, Ou Pu Lighting Ma Xiuhui and Wang Yaohai were ranked 747, compared with last year's ranking of 87, the wealth value reached 22 billion yuan, an increase of 40%.
As the overall lighting solution provider in China's lighting industry benchmark, Optel Lighting's retail price and gross margin are both leading in the industry, and in the context of the ongoing price war in the LED lighting industry, the gross profit margin has increased year by year. In recent years, Op Lighting has invested a large amount of resources in the construction of a diversified channel network, and has enriched its form on the basis of the original terminal stores, creating Western-style retro lighting stores, integrated home stores, and Qianping stores. Under the current trend of consumption upgrades and the gradual replacement of pure light source products by lighting products, the company is expected to continue its high growth with its brand and channel advantages.
The performance report released by Op Lighting on January 31 showed that the company's operating income in 2017 was 6.957 billion, up 27.03% year-on-year; the net profit attributable to shareholders of listed companies was 680 million, an increase of 34.44%.
In addition, Mr. Sun Qinghuan, chairman of Mulinsen, ranked 996th with 18 billion yuan, ranking 176, and wealth increased by 47% year-on-year.
As a leading LED packaging company in China, Mulinsen has been focusing on the R&D, production and sales of LED packaging and application products. It is a major supplier of LED packaging and application products in China. Through continuous integration of the upstream and downstream of the LED industry chain, Mulinsen has continuously expanded its sales channels through the integration of industrial chains and cooperation with well-known foreign companies. Introduce excellent management talents, improve the training of talents, consolidate the company's core competitive advantages, and promote the company's business scale to continue to grow and develop, and the industry's leading position is further consolidated.
On the evening of March 4, Mulinsen released the “Annual Report 2017â€. The report showed that the company achieved operating income of 8.169 billion yuan, up 47.97% year-on-year; net profit attributable to shareholders of listed companies was 669 million yuan, up 41.20% year-on-year.
Together with Ma Xiuhui and Wang Yaohai, Ms. Mu Qinghuan, chairman of Mulinsen, also listed on the list of Gu Wei, chairman of Zhaochi. Gu Wei ranked 1857 with 9.5 billion yuan, and the wealth value increased by 7%.
According to public information, Zhaochi has only entered the midstream packaging industry and downstream application fields of the industrial chain in 2011. After several years of steady development, it has become a leading LED enterprise in China. On the basis of the good growth of LED packaging and lighting business, Zhaochi shares began to expand into the field of LED epitaxial wafers and chips last year. According to the announcement, the upstream chip layout of Zhaochi has achieved substantial progress. Recently, Zhaochi shares a contract with Zhongwei Semiconductor for the purchase of 100 MOCVD equipment.
According to the 2017 annual performance report released by Zhaochi, the company's total operating income was about 10.317 billion yuan, up 37.98% year-on-year; the net profit attributable to shareholders of listed companies was 611 million yuan, up 63.25% year-on-year. In the future, under the synergy effect and scale effect of upstream and downstream, Zhaochi is expected to further achieve breakthroughs.
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.
