LEDforum 2011 Shenzhen (two): LED lighting is one of the most efficient energy-saving light sources

Seoul Semiconductor provides one-stop service for LED customers

Seoul semiconductor (Seoul Semiconductor) Mr. Pan Guojie China FAE manager, introduced Seoul's flagship product, and from the technical aspects of the design process were analyzed.

He pointed out that the Acriche resolution for Chinese translation is the top of the semiconductor lighting technology, at present, Seoul semiconductor has to provide one-stop service for LED customers, including LED chip, LED packaging and application of LED terminal products etc..

He pointed out that compared with the traditional DC LED AC LED, with components use less, cost savings for the converter assembly and component design and use life because there is no current converter, up to 35000 hours, the effectiveness of no conversion loss and other advantages. In order to elaborate, Mr. Pan Guojie also in Seoul Acriche, Z-Power LED, direct type LED; side light type LED, Lamp LED, in-line patch type chip LED, piranha LED; dot matrix display, customized display; deep ultraviolet, near ultraviolet and other products as an example, from the technical details the design of 150W high shed light design, 10W outdoor LED light engine lamp design, engine.

The largest market value of building lighting applications for LED lighting

Accumulation (Macroblock) chairman Dr. Yang Lichang introduced in the end application development trend of LED lighting: use RGB LED to replace the traditional neon lamp has formed industry trends; commercial space use "curtain" or "shaped screen" gradually increase; LED label will replace the traditional label.

Dr. Yang first introduced the 2008-2012 annual output value of LED lighting in the application market, the output value is the largest building lighting market in 2008 was $203 million, as of February 2011 has increased to $491 million, he also predicted in February 2012 will increase to $684 million. Secondly, the greater the value of the application of Retail display, as of February 2011, the output value of the application area has increased from $135 million in 2008 to $34 million, in 2012 is estimated to increase to $193 million.

In LED lighting market, he said, at present, the application of LED in the high-end architectural lighting products in the area of the highest quality, but the amount is less. The application of the low end of the field, the largest amount of products, but the price is low. At the same time, he also believes that the practical application of building lighting waterproof, electromagnetic radiation, hot insertion and other issues need to be handled with care.

The application, in the commercial space he introduced, the application includes LED decorative lighting (such as curtains, screen shaped screen), stage lighting (LED stage lights, LED display), application of LED signs in three aspects. The commercial space use "curtain" or "shaped screen" gradually increase, mainly because it is the "light" and "thin" and "irregular" signs; LED dynamic display features, will become the LED label to replace the traditional signs of the driving force; using RGBLED to replace the traditional neon lamp has formed industry trend.

Shanghai blue power chip luminous efficiency reached 120lm/w

Shanghai blue (Epilight) Dr. Hao Maosheng introduction, the company is engaged in the mainland's first GaN based LED epitaxial wafer and chip R & D and production of industrial enterprises, located in the field of Optoelectronics science and technology achievements Chinese national "863" plan into the base. By the end of 2010, the Shanghai headquarters of the company has 20 MOCVD production lines, with an annual output of blue green LED chip 10 billion. At the same time, the company's production base in Anhui plans 200 MOCVD production lines, a phase of the construction of 50, the construction of the two phase of the 150.

The company's main products are high brightness GaN Blue and green wafer and chip. High power chip (45*45 mil) luminous efficiency of 120lm/w @ 350mA, production level has reached 100 lm/w @ 350mA. Small power chip (10*23 mil) production level has reached 7lm @ 20mA.

In addition, Dr. Hao also introduced the high-end chip technology, such as PSS technology, epitaxy, chip technology, thin film technology and the vertical structure of interfacial roughening technology.

Finally, he concluded that the Shanghai blue presents a new technique of lateral epitaxial mask, with GaN thin films grown on sapphire substrate with lower dislocation density; another significant characteristic of this method is the formation of high density nano pits in situ sapphire substrate surface. The rough interface between the substrate and the GaN greatly improves the light extraction efficiency of LED.

LED lighting is one of the most efficient energy-saving light sources

LEDinside storage analyst introduces the current development status, the traditional lighting and LED lighting of various LED applications and development in the super, LED lighting development trend and Japan at the Lighting Fair2011 show is analyzed.

Storage in ultra pointed out that the current lighting electricity consumption accounted for the proportion of about 19%, converted into electric power consumption of up to 2651 TWh. The use of existing energy-saving lamps are the most efficient to replace the existing lighting device, will be able to save 30% of lighting energy consumption, if combined with intelligent lighting network environment, has the potential to save more than 30%, LED lighting is one of the most efficient energy-saving light source.

In a variety of applications in LED, 2010, global lighting output value of $793 billion dollars, while in 2010 the global LED lighting output value of $36 billion dollars, the application of LED lighting construction accounted for the largest, reaching 33%, followed by the replacement project of lighting and outdoor lighting (19%), (13%).

The development trend of LEDinside Lighting Fair 2011 LED lighting observation that: Although the Lighting Fair 2011 as the main lighting exhibition in the exhibition, but
