Dongguan LED development is uneven and hopes to cooperate with Taiwan-funded chip factory

The LED industry chain planned by Dongguan City, Guangdong Province is accelerating. It is expected to contribute RMB 15 billion in output value in 2015. At the same time, in view of the fact that Dongguan LED industry is mostly a downstream packaging factory, it is hoped that a powerful Taiwan-funded LED chip factory will be introduced to bless.

At present, there are more than 60 enterprises engaged in the production and operation of LED lighting technology and products in Dongguan, with a total annual sales income of more than 2 billion. Although the LED industry in Dongguan is in full swing, according to the "Proposal on Actively and Steadily Promoting the Development of LED Industry in Our City" put forward by the Economic Committee of the CPPCC, it is pointed out that the development of LED industry in Dongguan is very uneven, and it is too concentrated in the downstream packaging field. . In addition, LED companies are independent and lack synergy.

The Economic Committee of the CPPCC of Dongguan believes that the development of the LED industry in Taiwan is long and the technological capability of the manufacturers is relatively superior. What is important is that the LED chip factory in Taiwan has better strength. This is the most lacking link in the LED industry chain in Dongguan. Can cooperate with Taiwan-funded LED companies, especially the LED chip factory.

The Dongguan CPPCC Economic Committee has also suggested that LED industry associations must be established and form an upstream and downstream industry chain. It is expected that by 2015, Dongguan will complete a complete LED semiconductor lighting industry chain, gathering more than 200 LED lighting companies, and the annual output value of the LED lighting industry will reach 15 billion yuan.

Li-Ion Battery With Smbus refers to the battery datas can be collect through equipments based on SMBUS data communication, it usually applied to the military grade battery which need higher safety level protection .but as these battery have SMBUS inside ,it also should meet these requirements as :

1.The rated voltage is high (the operating voltage of the unit is 3.7v or 3.2v), which is about equal to the series voltage of three nickel-cadmium or nickel-hydrogen charging batteries, so as to form the battery power supply group

2.The self-discharge rate is very low, which is one of the most prominent advantages of the battery. At present, it can reach less than 1% per month, less than 1/20 of the nickel hydrogen battery.
