If the light bulb is filled with colored liquid, it will be both eye-catching and energy-saving. Is it cool? If the price is lower, and then close to the people, there are probably many people who are willing to place an order.
Infineon Electronics (Hangzhou) Co., Ltd. produces a patented product every week through continuous innovation and research and development; at the same time, the price has become more and more close to the people. In 2010, the head of the company, Hua Guichao, was selected as a candidate for the CCTV annual economic figures. There are really two brushes.
The bulb is filled with liquid, beautiful and energy-saving. In the product showroom of Infineon, the reporter saw a lot of new LED products. The most curious for the reporter is the LED light bulb in the liquid. This bulb is filled with liquid and looks like water to the naked eye. The staff plugged the plug in, and the bulb filled with water lit up, brighter than the ordinary LED bulb.
The secret is in this special formula of special liquid, this is Infineon's liquid cooling technology, which can reduce the cost of LED lamps by 20, and greatly improve the light efficiency, life and brightness of the lamps.
From an aesthetic point of view, this liquid can be customized to various colors as needed, making the seemingly ordinary light bulb more individual. In terms of price, it is similar to an ordinary LED bulb.
Can a light bulb filled with water save more power? Its power saving is mainly reflected in the heat dissipation. The staff took out a common LED bulb and a liquid-cooled bulb for comparison. The upper part of the LED bulb is made of aluminum, which is used to dissipate heat. The liquid-cooled bulb mainly uses the liquid inside to dissipate heat. The reporter touched the light bulb and found that there was no warm feeling.
According to reports, if a light bulb consumes 3,000 watts, of which 2000 watts are used for heat generation, only 1000 watts are used for illuminating. According to the technician, the light source of the bulb will have light loss, whether it is through air, liquid or glass. However, the liquid-cooled bulb enters the liquid from the light source and then to the glass. Because the density is similar, the loss is reduced. Therefore, liquid-cooled bulbs have advantages in terms of light efficiency and refraction.
According to reports, Infineon's LED liquid cooling technology is also leading the world.
The price has dropped by half in three years. The price of LED is low and low. Our goal is to make LEDs more and more energy-efficient, and the price is getting closer to the people, making the products more cost-effective. Hua Guichao said. How to improve reliability and reduce costs is exactly what Infineon has been thinking and solving.
First look at the composition of an LED lamp, mainly four components: the outer casing, the heat sink, the light source, and the drive type. Hua Guichao said that in the past, the light source in the finished product accounted for about 50% of the cost. With the price of the upstream chip and so on being greatly reduced, the proportion is now reduced to 30, and the proportion of the driver is increased, from 15 last year to 20.
If the chip is likened to the brain of an LED, then the drive is its heart. The construction and technology of the drive is very complicated, with a high-power driver and five or six hundred components. And this is the advantage of Infinity. Since 2007, LED driver has been launched. In just three years, Infineon has become the world's number one LED driver.
Under the premise of ensuring reliability, Infineon has reduced the price of its drives year by year, resulting in a 15% annual decline in product costs. Take the 3-inch (10 cm diameter) LED downlight commonly used in daily decoration as an example. The market sales price was more than 200 yuan three years ago, but now it is only 100 yuan, and the price is reduced by nearly half.
With a super brain, it creates a new patent every week. Although it is a new company, it is a baby with a super brain. This is the price of the outside world. Dr. Huagui, a returning doctor, is more willing to be called a scientist.
Infineon is more like a research and development center than a manufacturing company. Hua Guichao said. As a high-tech company, in Infineon, most of the departments that reporters see are related to research, development, experimentation, and certification. At present, Infineon has 300 R&D personnel, accounting for nearly 45% of the company's total, and R&D investment accounts for about 10% of the company's sales revenue. Up to now, Infinex has applied for and authorized more than 375 patents, mostly invention patents, and dozens of international patents including US patents, which means creating a new technology every week. Invention, apply for a new patent.
In this way, under the protection of the patent-based intellectual property cluster, Infineon products can be sold globally without being hit, and Infineon also obtains technology licensing revenue through the authorization of patented technology. Thousands of dollars in return.
At present, Infineon is welcoming explosive growth: in 2007, the company was just established. The sales in that year were basically negligible. In 2008, it was 2.8 million yuan. In 2009, it suddenly increased to 28 million yuan. In 2010, it was leaps and bounds, 100 million yuan last year. The turnover has reached 220 million yuan, and both operating income and net profit have doubled.
LED market: Winter is coming, spring is not far away: Last year, due to the poor overall economic environment, LED companies have closed down sharply, while Infinex sales have doubled. Against the trend of growth, what is the secret of Infineon?
Hua Guichao: Infineon's strength lies in its strong R&D capabilities and technological innovations, providing cost-effective products, which is the competitive edge. At the same time, due to the early layout and leading technology, the overseas market sales were not dragged down by the economic downturn. Last year, sales increased by 300%.
Q: The photovoltaic industry, which once had a lot of scenery, is facing a crisis. Some people say that it is necessary to be alert to the LED step. What do you think?
Hua Guichao: I believe that LED is currently in the winter before the spring, and the second half of last year is much slower than expected, but with the advancement of technology and the reduction of cost, LED is getting closer and closer to the market, and the market is expected. The turning point will appear in the second half of the year. Under this expectation, Infinity's vision is to continue to double its output this year.
