The future of light-emitting diodes (LEDs) is bright
Although many people like the color of incandescent bulbs, no one wants to receive expensive electricity bills. If incandescent bulbs have no significant improvement in energy efficiency, the energy efficiency standards that are gradually promoted by countries around the world will drive incandescent bulbs out of the market. Investors are betting on other technologies that may dominate the market.
So far, the only products that can replace traditional light bulbs are compact fluorescent light (CFL), but these products contain mercury, and many people are not satisfied with their light quality. On the other hand, LED lighting Mercury free, long life and high energy efficiency.
Since the first actual development in 1962, LED has undergone a long-term development, originally only red, but now developers can produce LEDs of various colors in the spectrum.
LEDs require only 20% of the power of traditional incandescent bulbs. In the case of about 20% of the world's electricity used for lighting, switching to LED lighting will bring considerable energy savings and reduce greenhouse gas emissions. At this moment, countries around the world are arguing over how to price carbon dioxide pollution.
LED cost is too high, is the biggest obstacle to the market to adopt LED lighting. Many experts pointed out that if the LED lighting market is to take off, the price of high-quality LED bulbs must be reduced to less than 10 US dollars. The current LED bulb price is more than 10 dollars. Several times. Investors strongly expect that as LED grass-roots enterprises reach economies of scale and technology continues to advance, costs will fall rapidly.
"In the past 12 months, the market has really begun to change." Warner Philips, co-founder of LED grass-creation company Lemnis Lighting, said he is also the founder of Dutch electronics giant Philips Electronics.
Lemnis launched the first LED bulb called Pharox about four years ago, which can be mounted on a traditional lamp holder. If it is illuminated for four hours a day, the latest version of the LED bulb can last up to about 25 years, but each cable The price is 25 dollars.
LED bulb prices have been in a short period of time. About six months ago, Lemnis sold LED bulbs for about $50 each, and Philips expects prices to fall by an important level of $10 in the near future. "This may be next year." Realized in the first half of the year," he said.
** Optimistic growth estimate**
Pike Research, which tracks the LED lighting market, predicts that by 2020, LED lighting will account for nearly 50% of the US$4.4 billion commercial, industrial and outdoor lighting market. Even though current prices are high, some commercial facilities and retailers have begun to switch. Installed.
At the end of last year, retail giant Wal-Mart (WMT.N: Quote) said that its 650 stores will install LED lighting equipment and choose to supply related products by Cree Inc (CREE.O: Quote); In the field, Cree is one of the few listed companies.
Other companies that modify LED lighting include coffee retailer Starbucks (SBUX.O: Quotes), restaurant chain owners Red Robin and Yum! Brands (YUM.N: Quotes).
Cree shares hit an all-time high of $83.38 in April this year, up nearly 49% since the beginning of the year, partly because the market has optimistic expectations for the LED lighting market. However, the global economic slowdown has cooled the expectations and caused the company's share price to return. Explore $65.
According to Cleantech Group data, in the first quarter of 2010, venture capitalists have invested $100 million in 14 LED lighting companies, up from $14 million in the same period last year.
Bridgelux, a manufacturer of high-power LED chips for the lighting industry, is preparing to launch the Silicon Valley plant, and investors are eager to invest in the company.
Bridgelux raised $80 million in funding earlier this year and declined some investors who want to participate in the stock market. "There are a lot of people coming to knock on our door," said company executive Bill Watkins.
