Explore the industry's future LED industry giants opinions

CREE, Lumileds (America and lumens) Nichia business representatives held in August 13th to August 15th of the Las Vegas LED Exhibition (LED Show) held a meeting to discuss the application of LED in the general lighting in the future, marketing manager Chad Stalker America participants are the products of Cree company sales manager Paul Scheidt, Nichia LED Sales Manager Erik Swenson and PHILPS lumens.

The theme of the conference is to investigate whether LED chips can continue to advance the lumen output and efficacy of lighting products at the same pace in recent years. The meeting discussed the direction of LED technology is more focused on how to meet different solid-state lighting (SSL) system of quality and cost objectives, the three representatives of the LED and SSL system will have a very different idea of how to develop.

PHILPS lumens representative Stalker first said that the future progress of LED in the future will be advanced in the system level component level, LED will continue to improve, but slower. He added, "LED systems will continue to drive improvements. "The content of his speech, including the progress of the component level, outside of efficacy, can improve the effectiveness of the system and provide a higher quality of light. He said that the use of better red LED and phosphor conversion white light LED mixing is critical, the use of lime green LED PHILPS Hue lamp is an example of color adjustable product trends.

On behalf of the Swenson view around Nichia power LED, he said, in power compared to LED high power LED can rapidly improve the product efficiency, provide better quality and appearance, to better meet the requirements of many applications. Medium power devices have the advantage of economies of scale is unmatched by high-power devices. Such as 757 LED applications include Nichia lamp, lamp, backlight display, car modification application, wide applicability is more likely to provide increased cost advantage. Medium power LED in the manufacturing sector also offers extraordinary benefits, and higher power output.

Cree on behalf of Paul Scheidt also like Stalker, focusing on system level issues. He said that the early LED relative to the driving, cooling and optical systems, pay more attention to the cost of their problems, and now, LED in the SSL system, the percentage of the cost has been steadily declining for many years. He cited several different ways to address the cost of the system, such as the use of different types of LED and different system architecture. He believes that AC-LED technology may be able to reduce the cost of the driver part, but the AC- driven design requires more LED, because at the same time not all LED are driven. He also said that the flicker problem of the AC system can not be solved, the EMI problem requires additional circuitry, essentially a driver ic. Speaking of medium power LED, Scheidt said, in many cases, the color of the LED conversion are not satisfied, the problem is that you want to force the drive LEDs, but tried to limit the number of LED in the system. But most of the comments on Scheidt power devices are directed at the plastic packaging LED. It is worth noting that Nichia said, the 757 LED is essentially a ceramic composite packaging. The company did not disclose details, but Swenson had previously said that the product provides lumen and color maintenance can match high power LED.

Scheidt concludes that, in many applications, such as retrofit lamps, high voltage, high power LED can provide the best system level approach. He said that these components simplify the driver design, but also meet the requirements of the application of light distribution and quality. Some SSL products, such as street lamps and ceiling troffers using a large number of single transmitter LED, has been a driver level of high voltage design, these products are very successful, with industry-leading SSL system efficacy.

According to the three representatives, the reporter a telephone interview with the world famous distributor WPG group's cloud services group marketing department Mr. Yu, he said on the phone, from now on the lighting market price trend, LED products have been gradually in the area of cost control has madeconsiderable progress, and in the last two years LED lighting products to replace the traditional lighting trend has become more and more fast, so the overall trend for a period of time in the future of the LED industry, can still maintain an optimistic attitude; on the other hand, as the core agent of CREE and Lumileds, WPG group will also be increasing the LED related products, technical marketing efforts in addition, the traditional business model now, enterprise users can already very convenient on the Internet through the WPG cloud services to obtain phase Support related LED products, technology, etc related, this is Mr. LED seems to accelerate the popularization of new technologies, promote LED products in the market share, has very positive meaning. Under the joint efforts of the original plant and distributors, Mr. Yu think the prospects for LED products or worthy of.
