Optoelectronic News Network: In the financial crisis, has your company been affected? What measures will be taken?
Shanmu shows: The impact is there, but not so big. In general, companies with low production and late start are less affected, or the impact has not yet arrived. Those companies with large output are definitely affected.
We are doing high-end products, the quantity is small but the price is high, mainly facing high-end customers, not the public, affordable people can still afford, and people who can't afford can't afford it. Moreover, our display screen is not limited by a certain professional field. It is used in various fields, and the coverage of users is large. Generally speaking, we are not affected much.
Customers need to change suppliers. For example, we have a price of 800,000 and others have offered 600,000. Although we have saved 200,000, if there is a problem with this 600,000 yuan, the loss will be great, and the high price will try. The cost is also very high, so our suppliers are relatively fixed. In this situation, ensuring quality is the key. If there is a problem with a small number of products, it is possible to give up the whole pot, so the things that are handed over to the customer must be guaranteed. In fact, those manufacturers with relatively low prices always have the reason for the low price. It is possible to use poorly poor materials, and the quality is the first for high-end products. Now we have to pay more attention to customer needs and better after-sales service than ever before. If we are profitable, we can also slightly lower our prices so that customers can buy in large quantities.
Due to the uncertainty of the future, some customers buy less, and want to buy ten instead of buying two, and want to slow down, do not want to buy so much at once, it has a certain impact on us. Our performance this year is similar to last year, and it has not been counted yet, probably tens of millions.
Optoelectronic News Network: Do you think there are problems in China's LED industry?
Shanmu shows: LED is different from traditional light bulbs. The traditional light bulb process is quite simple. Many factories can do it. LED is a high-tech product with various parameters such as wavelength and brightness. It is technically difficult. At present, many companies in China are launching LEDs, and there are many small factories that can guarantee the quality. Although LEDs can use 100,000 hours, they will fade after a certain period of time. If a lot of poor products flood the market, it will have a bad effect. Maybe people will switch to light bulbs, so the inferior products of small factories may harm the whole industry. For example, as for the Japanese, the LED lights sold more than one. Some domestic manufacturers sell less than a dime. If the quality is the same, the photos will be bankrupt, but people have billions of dollars in income a year. For the time being, no company can compete with Nichia.
TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.
It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.
TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.
The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
