In the global green trend, driven, LED lighting, green energy, electric / hybrid vehicles, conversion technology used in the next few years, generally optimistic about the market demand. Meanwhile, with the power structure of the industry and the increasing understanding of the product, the future supply options, both efficiency and power density and so should have made great progress, customers can expect to find more effective and reliable power management solutions.

Build green engine

As the energy continued tight supply, the market for energy-efficient products in an increasingly upward trend. ON Semiconductor (OnSemi) afterglow, marketing manager for power products that the widespread use of switching power supply is a typical example. For example, in the field of air power, inverter air conditioner previously only used in high-end switching power supplies, and a huge amount of traditional fixed-frequency air-conditioning is still the main power frequency transformer. But in 2010, replaced by frequency switching power supply transformer trend has started to emerge, is expected to show a substantial growth in future years; the other hand, has been used in the field of switching power supply, such as television, adapters, etc., lower power increasing consumption needs of the program. Accordingly, the afterglow of this year, analysts said, even the next few years, the Chinese market for AC / DC off-line controller (AC / DCOfflineController) demand will steadily increase.

Fairchild (Fairchild) computing product line manager Zhanzhen Hui said, AC / DC off-line controller in the Chinese power market a wide range of applications, covering DVD, STB, PC power supply, NB adapter, LCDTV, LCD displays, home appliances , LED lighting, and so on. “Although each application of the solutions are not the same, but they have a common trend: it is more efficient, slim profile, less component count and lower standby power consumption.” He emphasized that

From ON Semiconductor’s news, the company may apply to the TV, white goods, lighting, communications and other areas including the PWM controller, PFC controller, the secondary synchronous rectification controller, half-bridge driver, the output reference (TL431 ), including a series of high-power core control device. Afterglow that high efficiency, low standby power consumption of power management solutions, and reliable quality and good technical service will be the best competitive value Semiconductor embodiment (Electronic Engineering Times Copyright, declined reproduced).

Fairchild (Fairchild) flagship “green” brand series of PWM and integration in the energy-saving performance is also worth mentioning. The FAN6754, for example, the chip will not only satisfy the no-load power consumption <100mW of energy requirements, also has OVP, OCP, OLP, OPP, OTP, Brown-out and sense resistor short-circuit protection; FAN6755 is designed to meet the recently <100mW and the future of LCD display adapter <25mW stringent energy efficiency requirements introduced new products, technology allegedly used mWSaver switch in what is known as Zfb new energy-saving technologies; and FAN6863 6 feet for low-cost solution , to meet the <100mW of energy requirements.

Integration caused by competition

Persistence in an interview with EE Times, said ON Semiconductor’s future product roadmap will continue to focus on energy efficiency and low power supply expansion program. For example, for the power adapter, the target ultra-low standby power consumption of the new controller has been under development. New PFC controller allows light-load down-reduced switching losses and improve the average efficiency of PFC, high efficiency power supply is bound to become the first choice for the future; the same time, more compact and smaller PFC controller is also planned. On the other hand, high integration, powerful modular COMBO products (integrated PFC + PWM), ON Semiconductor will also be the focus of power management product development direction.

COMBO trend is clearly seen more than a Semiconductor, Fairchild Zhanzhen Hui also stressed in the field has a broad product portfolio.
For example, the T series FSFR1700-2100, is an integrated package in a single SIP9 the LLC controller, two 500VMOSFET and many other components COMBOIC. As the high efficiency, easy to implement slim design, fully able to meet current demand trends LEDTV slim design (EE copyright, declined reproduced).

Fairchild Power Switch (FPS) is the modular IC. DIP8 package it in a single integrated PWM, MOSFET and SenseFET, rated voltage 650V-800V, rated current 0.5A-7A, can be widely used in many different applications. Zhan Zhenhui further said that in FPS3 different sub-series, FSL series for low-cost solution, targeting the consumer market (DVD, set-top boxes, home appliances), mainly used to reduce standby power consumption; FSD series for the display device (LCDTV etc.); FSBH series is integrated 700VMOSFET and Brown-out functions, mainly for the PC in order to reduce standby power consumption. It also can help customers meet 2009ErP’s energy requirements, at 0.5W load conditions, the standby power consumption is still less than 1W.

Also uses an integrated IC design products also include integrated PFC and PWM functions FAN480x and FAN692x. The former for the forward topology can be used for PC power supply; the latter for flyback topology can be used for notebook adapters, LEDTV and lighting. Reported, compared to discrete component solutions, FAN692x be reduced by about 20 components, and also reduce the more than 50 FAN480x (EE copyrighted and may not reproduced).

In addition, Fairchild primary feedback regulator (PSR) also uses an innovative patented technology, primary side regulation to obtain an accurate constant current and voltage, and without feedback loop components. FAN10x independent type PSR controller, FSEZ1x7 the PSR and MOSFET integrated IC. These devices are now cell phone charger and a small power LED lighting solutions for the mainstream.

Although the same is with the incandescent light source, but with the same luminous flux of LED radiation heat much smaller volume and a small advantage, LED performance characteristics of the Chinese lighting manufacturer of innovative imagination opens the door. In the global green trend, increasingly more energy efficient alternative to traditional lighting LED lighting has become an indisputable fact.

When we carefully look around a bit, LED has been everywhere. We use the phone, behind the display and keys, backlit LED; we turn on the computer at work, rest, turn on the TV, the screen behind the colorful, high quality LED backlight module in the running; when driving home , our car’s taillights, brake lights are also likely to use the LED; in the building decoration, wall lights, all kinds of billboards, lights, etc., LED’s use has also been very full.

In addition, you still have some areas I do not often concerned about the future is likely to LED lighting applications will also be part of the site:

Warehouse Lighting: Most of the warehouses are to mercury vapor lamps for lighting, general specifications: Power 250W, luminosity 11,000 lm, color temperature 5,000 K, 8,000 hours of life. WPG WPI Group, Hong Kong’s vice president of marketing at ZHANG Guang-wen introduced as a new type of LED brightness improved a lot, and the high thermal efficiency, power, life expectancy of 35,000 hours, the price advantage, so the LED lights on the market warehouse is very competitive. ZHANG Guang-wen suggested that the choice of CreeXLampXM-L white LED. It’s cold white series, the maximum luminosity can be reached 280lm @ 700mA or 910lm @ 3A, while the luminous efficiency has 138lm / W.

Dental treatment: dental repair process, the final step need to be blue for the ceramic materials used for the aggregation of its Blu-ray intensity of at least 1,000 mW/cm2 and time to last for about 10 seconds. ZHANG Guang-wen, and now the newly developed blue LED, both the wavelength and power are is in compliance with these requirements. ZHANG Guang-wen suggested use CreeXLampMC-EBlue blue LED. It is the 4-chip package LED, the wavelength range 465-480nm, power is 1,480 mW @ 350mA.

Wireless control of LED lighting: Generally speaking, when we want to turn on or turn off a lamp, the lamp should go near the switch button or the control room. But if there is a remote hand controller, can freely switch that light, this will bring a lot of our daily life convenient. WPG’s WPI Group, Applied Technology Division Associate Lin Jian introduced, allowing for accommodation of all the lamps replaced with radio frequency receiver (RFreceiver) LED lamps, can be through a wireless controller (wirelessremotecontrol) independent of any control of each lamp at home and off or adjust the brightness and other features.

Lin Jian suggestions, you can add a power-driven part of the RF receiver to control the power switch or adjust the size of the drive current to achieve the dimming function. Marvell and Texas Instruments In addition to providing power solutions, also offers Wi-Fi or ZigBee wireless transmission solutions.

Institute of the University of California, Santa Barbara, said they found the use of LED technology for general lighting the root causes of inefficiency. Their findings will help engineers develop a new generation of high-performance, energy efficient lighting solutions to replace existing incandescent and fluorescent lamps.

VandeWalle professor and his colleagues are working to improve high-performance, non-toxic and long-life performance of nitride-based LED. They in-depth study in a long time, driven by high power LED light failure phenomenon. The reason for this phenomenon has led to much controversy, but the University of California, Santa Barbara researchers said they found the use of quantum mechanical calculations of the formation mechanism of this phenomenon.

They concluded, LED light failure (LEDdroop) by Auger recombination (Augerrecombination) caused. Auger recombination is occurring in the semiconductor, three charged particles react with each other but do not emit photons of the phenomenon. The researchers also found to contain a scattering of indirect Auger effect is very significant. This discovery makes the previous theoretical studies, the direct Auger process with the LED light failure prediction and actual measurement results can be inconsistent interpretation of the phenomenon.

In nitride-based LED, the process of formation of these non-direct the main Auger recombination. In the April 19 article published in the journal Applied Physics, the first author, University of California, Santa Barbara postdoctoral researcher Emmanouil Kioupakis says. This other authors Vande Walle, Patrick Rinke, Fritz Haber in Germany their Institute work, Kris D ELaney University of California, Santa Barbara is a scientist.

Researchers believe that because the Auger effect is the formation mechanism, so the LED light failure can not be eliminated, but can be minimized. With wider quantum wells, and non-polar or semi-polarization direction of the growth of the device, can reduce the carrier density.
