General Electric (GE) expects that most bulbs, including incandescent bulbs, will be replaced by LEDs in the next decade.

Maryrose Sylvester, who was appointed head of the Lighting Division in March of this year, said in an interview in New York City, “LEDs entering indoor general lighting have attracted more and more attention. By 2020, LED will open about 70 to 80 general lighting. market."

Siemens's subsidiaries OSRAM Opto Semiconductors, Philips and GE's traditional rivals have made similar growth forecasts. With the introduction of new regulations and the drop in LED prices, the attractiveness of LED lighting systems to individual consumers and commercial buyers has greatly increased.

Maryrose Sylvester stated that in order to capture market opportunities, GE Lighting’s spending on LED technology research and development has doubled in the past five years. But he did not give a specific number.

Munich-based Siemens AG expects that the LED market will grow to 13 billion U.S. dollars (approximately 980 million euros) by 2013. By 2016, it will increase another 44.9 month forecast. Philips in Amsterdam is expected to arrive in September. In 2015, LED will occupy 45 of the lighting market share.

Maryrose Sylvester said that since LED systems are relatively expensive in the early stages, it is important to show users how maintenance costs and energy savings generate return on investment. This is crucial.

Maryrose Sylvester said, “When we turned to LED technology, we learned that whether it is the owner or individual consumer of a commercial building owner or business, they are very aware of the energy consumption in the world today and pay more attention to improving consumer spending on energy. ”

Although LED bulbs are still more expensive than other bulbs, the price of LED bulbs has started to decline as environmental regulations have made energy conservation an important goal. In the United States, regulations to phase out 100-watt incandescent bulbs in 2007 will begin next year, followed by the phase-out of 75-watt bulbs in 2013 and the elimination of 40-watt and 60-watt bulbs in 2014.

The efficiency of an LED light bulb directly affects light production. In the case of incandescent light bulbs, the electrical heating of the filaments produces energy loss.

Since LED efficiency depends on the LED package and how it is configured, GE focuses on providing overall LED lighting system design for commercial customers instead of trying to make LED bulbs equivalent to incandescent bulbs. That's what Cree and other semiconductor chip suppliers are trying to do.

Maryrose Sylvester said, "Our expertise is to integrate the entire application and implement it into important applications."

Pike Research expects that by 2021, LED lighting will have a market share of 52 in the commercial lighting area alone. This year, the commercial lighting market is expected to reach 42 billion US dollars, and will reach the peak of 54 billion US dollars in 2012. With the increase in the use of LED lighting systems, the commercial lighting market will gradually decline to approximately US$30 billion by 2021.

New Asian companies can produce LED lighting system products at low cost. At present, leading industry giants such as GE and Siemens are facing competition from these companies. Market research company Frost.
