Aiming at new LED materials

[Source: "High-tech LED - Technology and Applications" February issue]

In January of this year, the “12th Five-Year Development Plan for New Materials Industry”, which was organized by the Ministry of Industry and Information Technology, was officially released. Together with the plan, the “New Materials Industry 12th Five-Year” Key Product Catalogue was released. From the key industrial bases to the development of new materials, and even the increase in the number of production capacity, the description of the documents can be described in detail.

According to the published development goals, by 2015, the total output value of domestic new materials industry will reach 2 trillion yuan, with an average annual growth rate of more than 25%; R&D investment will increase significantly, and R&D investment of key new materials enterprises will account for 5% of sales revenue; We will build 10 comprehensive leading enterprises with strong innovation ability, core competitiveness and new material sales revenue of over 15 billion yuan, and cultivate 20 professional backbone enterprises with new material sales income exceeding 5 billion yuan.

At the same time, the two documents include phosphors for white LEDs, high-end yttrium oxide semiconductor polishing fluids, gallium arsenide single crystal materials, high-grade diamonds, sapphire materials, silicon carbide wafers, and gallium nitride epitaxial wafers. A variety of LED lighting related key material product catalogs, and refined to performance indicators and capacity quantity indicators. Among them, for the industrialization of white LED phosphors, the goal of increasing the production capacity of luminescent materials by 0.5 million tons per year was proposed.

Obviously, relevant government departments in China are constantly giving more attention to the LED industry, especially in the upstream materials field, and strive to increase technological innovation and investment in special materials in a short period of time, and accelerate the pace of mass production to meet the rapid development of the LED industry. Urgent request.

At present, domestic material research and development and production enterprises generally face bottlenecks in development: First, LED enterprises are scattered and the production of materials is difficult to scale. Second, the average company is not willing to easily replace imported raw materials. Even if the basic performance of domestically produced materials is up to standard, there are general doubts about the long-term stability of domestically produced materials.

We know that overseas LED terminal manufacturers represented by Japan attach great importance to close cooperation with parts and raw material manufacturers in product development, and can communicate smoothly between upstream and downstream, regardless of manufacturing process, material usage and cost control. All have formed a perfect cooperation chain.

Recently, the world-renowned multinational group Styron has launched a variety of new resin materials for LED, and is fully committed to the Chinese market. Almost at the same time, Dow Corning also announced that it will soon launch a special adhesive for LED chips to make up for the shortage of existing materials. The same move is also the Japanese company Mitsubishi Chemical.

For most of the global material giants, although the scale of LED usage is still small, the field will become a new bright spot in the future of the electronic materials industry with the scale effect of the terminal lighting market in the future. So for them, LED is a new growth point worth paying attention to.

The huge LED material family consisting of chips and epitaxial materials, substrate materials, luminescent materials, packaging materials, heat dissipating materials, process auxiliary materials, etc., is an important foundation for the development of the LED industry, to improve the level of LED technology and speed up product updates. Replacing, reducing costs and popularizing applications is critical.

In the future, as the LED industry gradually fades away from high-margin coats, manufacturing demand that strictly controls production costs and continuously improves the process level will be the engine of continuous growth of the LED materials industry. A consistent optimistic view of the future development of the LED industry also indicates that the development of the LED materials industry faces a rare market opportunity.

Vibration speaker:

 

Vibration speaker is a kind of speaker unit which is made from vibration principle. It is also called resonance speaker. Vibration Speakers have no diaphragms and also called exciters. They drive any solid plane surface they contact and made that surface sound, so people can have original sound from different materials. Vibration speakers have a special penetrability which traditional speakers don`t have. These kind of speakers are mainly used for digital audio speakers, music massage facilities and music treatment facilities.

 

Our main vibration speakers include:

1)    From the diameter: we have speakers in diameter of 18mm ~ 44mm.

2)    From the power output, we have speakers of 2W ~ 15W.
