LED light source is stuck in the future
Not long ago, after the review of the budget, the Taichung City Council in Taiwan decided to delete the news of the 79 million LED subsidy. Member Li Zhong said that the LED street lamp has insufficient illumination and the failure rate is very high. After the installation of the street lamp, the maintenance fee is required, and the purpose of saving money is not achieved.
Coincidentally, Guangdong’s public lighting has been strongly questioned in the past three years. The industry believes that the regional mandatory replacement technology is not mature, and the LED lighting products with low technology content cannot be ignored. The bigger problem is that LED lighting products need to consume a lot of non-ferrous metal resources, which is not in line with the national energy-saving and low-carbon policy. Therefore, the application of LED to public lighting has certain risks.
After the carnival in previous years, the aftermath of the LED lighting industry has been continuously revealed, and the reshuffle period may last until the middle of 2014. If LED lighting companies do not see the market environment in time, it is possible to repeat the photovoltaic industry reclamation.
For a time, the LED light source that has been optimistic about the government and the industry has been caught in a deadlock. At the same time, from another perspective, the industry after the chaos began to calmly think about the future direction of LED light sources.
Be wary of "good deeds"
A few days ago, Shanghai-based people said that LED lighting was once the "Xiangxiang" in the eyes of the government in Shanghai, and it gave huge subsidies to LED upstream chip companies. However, this year, subsidized companies have not achieved any results, and the source said that Shanghai began to curb the development of LED lighting. In 2009, the Yangzhou Municipal Government of Jiangsu Province introduced the MOCVD subsidy policy, which enabled other local governments in China to follow suit. However, at the beginning of last year, Yangzhou stopped the MOCVD subsidy policy, and the MOCVD subsidies were gradually stopped. Obviously, if the person disclosed by the insider reveals that Shanghai will begin to curb the development of LED light sources, then this is likely to be a microcosm of the development of LED light sources in the country. The development plans of LED light sources by various governments are gradually becoming more rational.
Since the development of LED, the policy subsidies have been introduced one after another, from upstream equipment to downstream application procurement. However, how many enterprises are really rushing for research and development, for expanding production, and contributing to the development of the industry, rather than treating themselves as “pocket money� If subsidies are in place, enterprise development is not effective, what should the government take? Means to save? Does it need to be held accountable for legal procedures? Or does it mean that the people’s hard-earned money can be lost without being investigated? In addition, what kind of situation will the subsidized enterprises face when the huge financial subsidy policy is terminated? What is the impact on the industry? These important issues require in-depth thinking.
From a glimpse to the current "bamboo baskets to fight water," government subsidies are understandable, but the development path of guiding ideology and choice should obviously be rethought, and vigilance becomes "good deeds."

Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
