Infineon: a world-class LED driver power producer

[Source: Gaogong LED 's " LED Good Products" magazine May issue reporter / Long Zonghui] "LED drive power is the core component of the luminaire, we advocate good products, distinctive products, fine products, and win the market with products. "Infineon Electronics (Hangzhou) Co., Ltd. (hereinafter referred to as "Infineon") market planning department director Mao Zhaoyu said that if the LED driver industry all go to the low-end market, quality can not be guaranteed, in the long run, will This caused users to have a crisis of trust in LED products.

"Technology Control" Infineon was established in September 2007. At present, its main products include indoor power supply, outdoor power supply, intelligent controller and other products. From the perspective of the power of the product, it fully meets the driving power products of different voltage levels in the world, and fully covers the driving power required for LED lighting fixtures in the 0-300W power range.

Targeted R&D

Continuously improving power performance, improving efficiency, improving reliability, grasping market trends and demands, and combining technical advantages with the market, and carrying out targeted and directional research and development are the technical goals that Infineon is constantly pursuing.

“Small size, integration, and dimming are the development direction of indoor LED driver.” Innolux said that Infineon is committed to using highly integrated chips to minimize circuit design and minimize the way by streamlining peripheral materials. Volume and weight. Under the premise of streamlining the structure, realize the technical goal of low cost, high reliability and dimming.

For high-power drive power supplies, the reliability of outdoor power supplies is an eternal topic of LED drive power. While continuously improving reliability, the market has reached a consensus on the realization of intelligent, standardized and modular LED lighting. If a number of LED power supplies and heat sinks are integrated into the light distribution, heat dissipation and dustproof and waterproof modules, the lamps are also composed of multiple modules, and the power supply can be powered by multiple constant currents, and each module is separately powered, so that even a single Module failure will not affect other working circuits, thus effectively avoiding the failure of the entire lamp. At the same time, such a design simplifies maintenance steps and reduces maintenance costs. In addition, intelligence is also the research direction of LED drive power, dimming LED street lights and tunnel lights in different time periods, which can achieve secondary energy saving and extend the life of the whole lamp. Based on the LED intelligent lighting control system, it can also create rich lighting scenes, achieve the consistency of time control, eliminate the time error of the power supply system, and ensure the quality of the LED lighting scenes.

At present, many power supply manufacturers directly adopt the topology solution provided by the IC factory. Mao Zhaoxuan believes that the topology solution provided by the IC factory is not a panacea. If all are directly applied, the LED power supply enterprise will directly become an assembly plant. In fact, we have to solve a lot of problems, such as material system matching, EMC optimization, efficiency improvement, life and reliability assurance, obviously there is an IC company's reference design is completely unworkable. “Infante is committed to working with IC manufacturers to develop better and more optimized circuit designs, which will gradually increase the cost performance and reliability of power supplies,” said Mao Zhaoyu.

Positioning the global market

With continuous technological innovation and product quality, Infineon Power can still provide reliable and stable power support for LED lamps in the face of complex and ever-changing external environments.

“Excellent quality and production technology, as well as the company's accumulated experience over the years, have made us confident to position our outdoor products in the mid-to-high-end market.” Mao Zhaoxi said that from the current sales ratio, high-power power sources are less powerful than indoors. The driving power supply accounts for a slightly higher proportion of sales, but in abundance, the indoor power supply does not lose the outdoor high-power power supply. Faced with a wide variety of indoor lighting and a wide range of applications, Infineon is committed to making power drivers more flexible while controlling costs. In addition, in addition to products, Infineon can also help customers to provide better overall solutions, such as multi-function controllers and accessories, and assist our high-quality services to seize the power market.
