AC light emitting diode (AC LED ) chip factories have to increase the proportion of LED chip developed high-voltage (HV) . Under AC LED technology shackles difficult to break through, the brightness of the delay catch up to the traditional direct current (DC) LED, therefore, the AC LED suppliers competing aggravate both HV LED luminous efficiency and heat dissipation advantage layout to make up for the AC LED product line the loss of revenue.
Fuhua Electronic LED Division senior manager Chen Dongliang, AC LED supply chain vendors have turned to aggravate the layout of HV LED and DC LED fierce face DC LED luminous efficiency and price offensive.
Fuhua Electronic LED Division senior manager Chen Dongliang the still gap at this stage AC LED brightness DC LED up to 60 to 70%, and the price is still higher than the DC LED therefore EPISTAR, Seoul Semiconductor (Seoul Semiconductor), Samsung Electronics ( Samsung) AC LED chip manufacturer's product strategy has also reversed course and turned to hug the HV LED, in order to grasp the more common lighting opportunities.
Recently, AC LED chip and packaging maker Seoul Semiconductor is already through as many as sixteen HV LED with rectifier development starting light efficiency of 100 lumens per watt AC LED module Acrich2, and by virtue of the integration of multi-cell (Integrated Multi -cell) technology to enhance the power factor (PF) of 0.99, to reduce electricity consumption by up to 50% compared to the previous generation.
Chen Dongliang AC LED luminous efficiency is difficult to meet the requirements of the lighting market, actively explore the application of the territory of the candle lights with small bulbs, contingent confined price is higher than the DC LED, aspiring difficult stretch this reason, Seoul Semiconductor is trying by HV LED equipped with rectifier, to build AC LED modules, actively to snatch Universal lighting market pie.
However, Epistar, Seoul Semiconductor, Samsung the HV LED die manufacturers use different core technologies, so developers HC LED architecture is different luminous efficiency is also large relative diameter with. Epistar the HV LED luminous efficiency has reached 150 lumens per watt; Seoul Semiconductor and Samsung luminous efficiency, up to 100 lumens per watt.
Chen Dongliang think, to enhance the brightness and lower prices for HV LED Seoul Semiconductor built to expand the primary task of the forces of plate, HV LED advertised 8 watts, 600 lumens AC LED module, for example, the the overall modules offer more than 3 U.S. dollars; However, Nichia (Nichia) DC LED the per watt quotes about NT $ 8 million, the translation of the the eight DC LED modules offer only about $ 3, which shows that the the HV LED costs are still falling space.
By DC LED luminous efficiency trot the upgrade price plunged impact, not only AC LED upstream epitaxy and LED chip suppliers, packaging and lighting industry also affected.
The microprobe was that mentioned the beginning of 2011, Fuhua Electronic branched out into the downstream lighting system from the AC LED package plant, in order to expand the product to the sea, but by the Japanese downturn spread from the point of view of three monthly shipments of AC SMD LED package one hundred thousand to one hundred thousand decline, Fuhua Electronics also started DC LED deployment, today a large amount of orders to DC LED-based lighting products mainly supplied to the parent company Datong's.

Several Key Parameters of LED Chip Selection Must be Noted
Energy efficiency rising costs continue to decline with the led,, LED Lighting massive popularity of the era is coming, LED lighting has become the hottest industry topics, LED lighting design involves optical, thermal, microelectronics technology, so LED designers usually more concerned about the appearance of the lighting, cooling, drive circuit design factors, to the neglect of the problem of the selection of the LED chip.
2011 Munich Shanghai Electronics Show LED Innovation Forum, the Philips Lumileds Asia marketing director Zhou Xuejun published a paper entitled "to support the development of LED technology in lighting applications keynote to combine Philips Lumileds LED products, in this speech, Zhou Xuejun share views on the key parameters of the LED chip, it is very helpful for LED lighting designers.
Zhou Xuejun revealed that currently PhilipsLumileds batch shipped over one billion of high power LED chips, and accumulated 15,000 hours of measured data, in addition to 700 million hours of test data accumulated, these accumulated for LED lighting designers are very valuable experience.
"With the LED energy efficiency and rising costs continue to decline, LED chip price war has begun, At this time, in addition to cost considerations in the selection of the time, but also to give more consideration to some of the other key parameters, such as reliability indicators." Zhou Xuejun pointed out.
He considered to constitute LED reliability of the three indicators should be:
1. Lumen maintenance rate - no lumen maintenance, will lead to the same batch of LED lamps brightness varies, so engineers have to learn to look at this index curve.
2. Color stability, he prompts can be obtained by access to vendors LM-80 reports the relevant information.
To examine the reliability of the supply chain of suppliers - if not timely delivery, will result in orders to fly out of your hand!
In addition, he also pointed out to examine the quality of the LED light, the three elements of the light quality is consistency, no difference in color, which is essential for reliable LED lamps.
In addition, he revealed that the back has a two-dimensional code in PhilipsLumileds most new generation LUXEON3LED of products, access to the two-dimensional code, the chip can get a lot of information, such as date of manufacture, MOVCD information, which also facilitates the maintenance of the LED lamps.
