IIC energy-saving light source of concern, ZETEX into the hands of the LED Market

With the gradual deepening of the concept of green energy saving, LED lamp as a more reliable, lower power consumption of environmental protection is being more and more attention. In recent years, with the white LED patent loosening and production capacity, in the past hinder the popularity of LED negative factors are being swept away. In this IIC, ZETEX exhibited the latest LED driver solution.

ZETEX ZXLD1360 driver for the latest buck drive, support 7V to 30V power supply range, the output power of up to 24W, suitable for high power lighting applications. Through the external DC voltage or PWM control signal, the output current can be adjusted up and down to achieve the purpose of controlling the brightness of LED. Compared with the existing drive 1350 of ZETEX, the 1360 can provide a higher adjustable output current (350mA = 1350, = 1A). In the ZETEX roadmap, will also launch 60V, 1A driver ZXLD1362 and easy to configure, support, buck boost and buck / boost working mode of ZXLD1380, and for ZXSC380 single cell voltage and low voltage LED applications simple instructions.

Zetex semiconductor company special standard products division chief marketing director Mr. Luo Guowei said in the introduction of new products: high efficiency and small volume is the biggest advantage of ZETEX driver. ZXLD1360 efficiency of more than 90%, and 1350/1360/1362 products are used in the TSOT23-5 package, only 5 pin feet, accounting for a small area of the board. The upcoming 1380 has 16 pin feet, followed by a more perfect control function

.

Zetex business development manager Zou Baiqiang said that in the design of the actual lighting applications, engineers lack of knowledge of optics is becoming a major challenge in the design. Because in lighting applications, in addition to the part of the circuit, the engineer must also consider the matching of the circuit and mechanical structure and the control of the light source, such as brightness, focus and other issues. ZETEX has accumulated some valuable experience in this area, can provide customers with better support.

At present, ZETEX and OSRAM, Lumileds, CREE and other white LED manufacturers have close relations of cooperation, the two sides will work together to promote the popularity of LED light source. In a variety of ZETEX demo version of the use of white LED covers almost all the mainstream white LED manufacturers.

The application of LED is mainly focused on the application of portable devices such as backlight, flashlight, safety lamp, wall decoration of buildings, commercial billboards, digital camera flash and so on. Mr Luo Guowei said: "the vehicle design cycle is relatively long, the lighting system is also very important for the safety of cars, car manufacturers are generally more cautious, so the LED light source comprehensive stationed in the automotive sector also need to wait for a period of time, but believe it will grow into one of the important applications of LED. At present, LED light source has been in a number of well-known automobile manufacturers or concept car interior lighting small dew skill, is very promising, it seems just need some time to prove myself and to further improve the technology (such as heat). So the next question is, when the LED light source occupied by the family as a unit of the huge market, to replace the thousands of families of tungsten filament lamp?

In fact, in some countries, Australia and Europe and the United States have mandatory energy-saving lamp replacement on the agenda, on the other hand, the LED lamp lumens is increasing, while the cost is declining in the whole life of the LED lamp has cost is lower than traditional incandescent light, seems to all levels, can at present in the domestic market is still in the initial stage of LED lamp. At this point, Mr. Luo Guowei is a bit helpless: "the popularity of the idea of people to a certain extent, also hindered the LED light source in the home, after all, most people still care about the initial investment cost, rarely will anyone really go to the calculation and comparison of two kinds of light source and reflected in the life of electricity the economic benefits of the single. "

However, the price of LED lights are still falling, with energy saving and environmental protection are becoming a kind of fashion, we have reason to believe that more in line with the requirements of environmental protection LED light source will be more users favor in the future, grow into a huge market.
