Electronic Fans News: On January 16, 2013, Beijing time, at the 2nd "Industry and Technology Trends Media Seminar" hosted by Evis, Mr. Lance Zheng, Marvell Green Technology Product Marketing Director, shared how Marvell relied on innovation The intelligent lighting control technology and solutions came to the top in the field of LED drive electronics, and played its role in promoting the popularity of LED lighting.
Mr. Lance Zheng, Marvell Green Technology Product Technology Marketing Director
Lance talked about the theme of "what is the innovation of LED driver" from three aspects. First, it analyzed the LED lighting market and the trend of LED driver technology; then it proposed how to innovate to promote the popularity of LED lighting; and finally described Marvell What role do they play in commercial lighting and the sharing of specific solutions.
New trends in LED lighting Marvell's new opportunities
Regarding the trend of LED lighting, he talked about it in two parts: one is indoor lighting. He believes that the overall LED lighting cost has dropped significantly last year, and pointed out that this is good news, so he concluded that this year is a very critical year for LED lighting. Next year and the following year is a stage of explosive growth; based on this, Marvell introduced a set of schemes that dimming and non-dimming driving costs are 20% less; the second is commercial lighting, all of his lighting from Walmart supermarkets in the United States Changing to dimmable makes it clear that the popularization of this industry is accelerating, and shows that the control technology in LED lighting is very important. So far, there is only one standard for a technology called data dimming control interface. Such technology was 10 years ago. Since its invention in Europe, it is now popularizing and is shifting from Europe to Asia; Marvell also launched the first auto-dimming chip last year. The effect is very good. All mainstream lighting companies have either mass production or are preparing for mass production. .
In terms of driving electronic innovation, Lance believes that the issue of innovation should be addressed from the three most important aspects that people generally pay attention to: cost, compatibility, and willingness.
In the above three aspects, he believes that the biggest problem is that the cost of LED and driving is quite high, the price has remained high, and it is maintained at about 2-3 US dollars, which is a big challenge for LED; for the volume, everyone Seeing that this light bulb is very small, it is very difficult to put the LED driver electronics into it. The LED consumption in Japan is very large. The most popular light bulb is E-17, which is very small.
There is also compatibility with existing lighting architectures. The most important thing here is the dimmer. If you want to keep it working, you need to provide current. And there is no standard when cutting the dimmer, there are very deep, very shallow, some of the first cycle and the second cycle are different, which causes a problem: when you put the LED driver electronics into the bulb , Because it is a switching power supply, it is difficult to be compatible. Lance mentioned that consumer expectations are high. An incandescent lamp may be worth US $ 1, and an LED bulb is US $ 10, so consumer expectations are of course high; Marvell ’s driving scheme can adjust the color, and this additional aspect can be provided to consumers It makes consumers feel worthwhile. Therefore, LED drive electronics is the most important role in the popularization of the entire LED lighting business.
High Voltage Laboratory Power Supplies
The LTP series laboratory high-voltage power supply is a high-voltage power supply specially designed for high-voltage laboratory applications with high precision, high stability, and low ripple output characteristics. Built in 19 inches, 2U standard chassis with designed output power at 1KW and output voltage ranges 1KV to 60KV.
After optimizing the output stability and output ripple on the basis of the 1KW high-voltage power module, the stability and ripple of the high voltage lab power supplies can reach the level at 0.1%.
The high-voltage laboratory power supply is also a constant-voltage and constant-current type high-voltage power supply. The output voltage and current can be continuously adjusted from 0 to the rated value via the added control potentiometers added to the front panel, high resolution LEDs display for output KV and mA are also added for intuitive measuring of high voltage laboratory bench.
The lab high voltage power supply is also equipped with DB9 interface as standard. Customers can apply 0-10V signals and dry contact signals to the interface according to our interface definition to achieve comprehensive control and monitoring functions on the power supply, like high voltage start / stop, output setting and reading.
The LTP series laboratory high voltage power supply is equipped with complete protection functions, which can deal with sparking, short circuit, overload, load discharge and other situations.
At present, the high-voltage laboratory power supply is mainly used in Laboratory power, High-voltage test stands, Electrostatics, Capacitor / Insulations testing and Electrophoresis applications.
