High-tech LED network news (Reporter Tang Guirong) As a company founded by Philips more than 50 years ago, NXP Semiconductors (NXP), although independent in 2006, still follows the strategic route of Philips Lighting: unique, integrated, design Turn.

As NXP's global vice president Russell has repeatedly stressed in an interview with Gao Gong LED reporter: Our focus is on upgrading technology and applications, and strengthening technical exchanges. Based on the positioning of the overall lighting solution provider, this year NXP joined its agent Zengyouqiang (Shenzhen) Co., Ltd., and launched dozens of LED lighting solutions.
"At present, the company has two fields with rapid growth. One is intelligent identification, and the other is LED lighting. LED lighting is an emerging industry and the focus of our future development." Russell said that the company's total IC chip production capacity in 2010 It has reached 65 billion pieces and has an important market share in the world.
In 2010, NXP established a chip R&D center in Shanghai. In the words of Russell, "Our market, R&D, and application centers are all located in China, and we have established technical and application teams throughout the country to understand market demand and serve customers. We are confident that we can do better in the LED lighting industry. â€
Non-isolated LED driver ICs dramatically reduce costs
High-tech LED: It is understood that the price of LED lighting products has dropped a lot this year. The LED driver IC industry is also in a price pain period. Many companies rely on the volume list. How long do you think the LED driver IC's pain period will last?
Russell: The price cut in the semiconductor industry is normal, mainly to see which way to use it. It is an important and positive way to cut prices by sacrificing profits to gain technological innovation. But the most serious price cut is the light source part.
From a system perspective, the LED driver ICs currently on the market are mainly isolated, and we are introducing non-isolated driver ICs. The non-isolated type does not require the use of a transformer, which reduces overall cost by 20% and efficiency by 5%.
High-tech LED: Currently incandescent lamps are also non-isolated, but there are safety issues. Different housing materials have different heat dissipation problems. How does your non-isolation solution solve the safety and cooling problems? How to promote?
Russell: From a technical point of view, LEDs can solve heat dissipation and safety problems. The key lies in mechanical structure and material selection. In recent years, the development of heat dissipation technology has been rapid, and new products have been introduced continuously, and prices have become cheaper and cheaper. In the past, plastic heat-dissipating materials were more expensive than aluminum, and now plastics have also cut prices.
In terms of efficiency, we are a semiconductor company, and the goal is to make it change cold and solve heat dissipation problems by increasing efficiency.
In terms of potential, LED power is low, safer and more energy efficient than incandescent lamps. LEDs are safer and safer to dissipate heat, because of lower power, they are safer than incandescent bulbs.
I think that the current LED lighting is not lacking in technology and lacking in the market. There is a direction, and then we can do it in this direction.
Complementary technical cooperation
High-tech LED: In the past year, NXP has held seminars on lighting promotion programs in many cities in China. Where does NXP put LED lighting? What is the consideration for holding a roving seminar in the country?
Russell: Our focus is on green lighting. However, the current lighting is not only in LED, Philips lighting has four main applications: LED, energy-saving lamps, fluorescent lamps, gas discharge lamps. Our products correspond to them. Although LEDs are the future development trend in place of energy-saving lamps, in terms of quantity, there are still far more energy-saving lamps than LEDs.
High-tech LED: It is understood that NXP was once part of Philips Semiconductors and became independent in 2006. Philips is a huge lighting group. What lighting applications are worth learning?
Russell: At present, NXP's driver ICs are widely used in lighting applications. Secondly, we have advantages in terms of product reliability, performance, system finished product, efficiency, etc., which is actually related to our previous semiconductor process and design experience.
High-tech LED: At present, some international driver IC manufacturers have changed the modular mode and turned off the IC after turning to LED lighting. Is there any conflict between this route and NXP's overall lighting promotion solution for driver ICs?
Russell: Modularization still requires IC, and modularity is the whole circuit board.
From the current positioning of the company, we only provide driver chips and solutions, and will not follow this model. Modules are very flexible and diverse, and it is difficult for semiconductor companies to create such a diverse range of products. There are many modular factories in China. If customers require modular design, then we will find partners to do their own advantages.
The market is changing very fast. We only provide one of the technical support. Whether our model is suitable or not, I think it is another thing. Every company will have different market positioning suitable for itself.
