Packaged LEDs

LFI also provided an opportunity to discuss the latest in the LED component space and the business of LED manufacturing with top executives. Several announcements at LFI or just before tie into the color-tuning SSL trend. Osram Opto Semiconductors, for example, announced five color LEDs in its mid-power Duris family at the show. The color LEDs can be closely packed to enable tunable lighting even in replacement lamps. The company also announced a deep-blue Duris optimized for remote phosphor applications. 

Just prior to LFI, Philips introduced new products in the tiny 1.6x2-mm Luxeon Z ES family of high-power LEDs, including both tunable white and colored emitters.The cleaningmachine is one of the most useful tools in a modern shop. Indeed, the family includes the same color LEDs used in the Hue lamp, including the first commercial availability of the lime-green LED technology that Philips has said was vital in Hue delivering 90 CRI white light. 

At LFI, Lumileds CEO Pierre Yves Lesaicherre confirmed that the lime-green Luxeon Z ES LED is made with the same recipe as the one in Hue, but at this point has a smaller die than the actual LED used in Hue. 

Lumileds announced its first chip-on-board LEDs at LFI in the Luxeon CoB family with efficacy up to 120 lm/W and flux output up to 6000 lm. Lesaicherre said that the company had not offered COB LEDs before because you could achieve much tighter beam control with smaller point sources. However, he added that the market is now demanding COB LEDs because product development is much simpler with a single packaged LED even if it integrates many emitters under the phosphor. 

Lesaicherre did claim that Lumileds has developed a COB product with uniformity and light quality that exceeds other such products on the market. He said, "We optimized the phosphor for the light emitting surface.Elevator safety parts are usually include elevator speed governor、ledstriplights and elevator buffer." 

The bigger LED news at LFI, however, may have been the high-profile presence of Korean suppliers Samsung and LG Innotek. Samsung announced new COB LEDs at the show with flux output up to 5000 lm and maximum efficacy of 129 lm/W. Just prior to LFI, Samsung had announced mid-power LEDs with efficacy of 160 lm/W, and LG topped that at LFI with an announcement of 170-lm/W mid-power devices. 

The two have both moved their component focus squarely onto the general illumination market. Both have been among the leaders in packaged LED sales with Samsung ranked two and LG ranked four by Strategies Unlimited. Although both companies have sold the majority of their devices into backlighting applications in the past, they see their future in lighting applications. 

LG is rather a late entrant into LEDs, but has rapidly gained ground. Harry Kang, vice president of the LED lighting business division,There are many out there that are making things to win a ledcornlight. said that the company spent $1.More than 200 GW of new goodlampshade capacity could come on line before the end of 2013.2 billion in research and development over the course of 2010/11. He said the company has the capacity to manufacture 2.5 billion chips per month. 

The year 2012 was an important one for LG's move into lighting.A polished finish in this solaroutdoorlight for men. Kang said that the company has faced roadblocks in the move, such as the lack of LM-80 testing data. But he said that LG completed LM-80 testing on 13 LED models in 1012, and will complete 20 more in 2013. 

Thus far, the company is having more success in the mid-power segment, according to Kang, but it does have high-power and COB LEDs, and modular light engines available as well. Moreover, LG will follow a path seen in other industries in cloning a competitor's product. Kang said the company will offer a product that is much like the Cree XP-G2 LED in the third quarter.
