Since many manufacturers can already manufacture LED chips with very high energy efficiency, reducing the unit lumen cost of high-quality white LEDs will be the top priority for LED development.
As the LED market continues to expand and expand, the value of production in 2010 has nearly doubled, and more and more semiconductor lighting bulbs have appeared on the shelves of household goods. It seems to tell people that the era of solid-state lighting has come.
In the past few years, the energy efficiency of white LED chips, packages, and lamps has been significantly improved, but general lighting is still at a very early stage of development.
Most assessments believe that current LED penetration in the general lighting sector is less than 5%. Although designers are keen to explore the various possible applications of LED lighting technology, consumers will be happy to accept lighting solutions that allow them to save money. However, LEDs still have many problems to be solved in order to dominate the lighting market. The status quo of LED lighting applications is a "when" problem, not "if."
Mark van den Berg, director of marketing for Europe, Middle East and Africa at Philips Lumileds, said that it will now focus on the quality and cost of LED lighting and systems. Earlier this month Mark van den Berg at the euroLED exhibition 2011 in Coventry, England, said: "The efficiency of the chip is already high, but we must provide a lower unit lumen cost to accelerate the LED lighting market. universal."
Van den Berg quoted the 20-fold improvement target mentioned in the DOE's latest MYPP plan to clarify how much the cost of a wide range of LED packaging applications should be reduced. That is, by 2020, the LED packaging cost will be 1 USD/1000 lm, while the LED luminaires will be only 5 USD/1000 lm.
As of 2010, the most advanced LED package costs float up and down at $10/1000lm. However, because blue light and phosphors are combined to achieve the best efficiency, this figure is only applicable to cool white light that designers and consumers dislike.
The US Department of Energy estimates that the cost of a 2010 warm white LED package is between $20 and $25/1000 lm. Recently reduced to 18 US dollars / 1000lm. Even so, Mark van den Berg's nearly 20-fold improvement goal is still achievable. The US Department of Energy has also set a mid-term target of $7.50/1000lm by 2015.
LED TV brings growth Strategies Unlimited analysts said that although general lighting gained strong market momentum in high-end applications in 2010, 93% of market growth is still driven mainly by TV backlights. "The use of LED products for TV backlights has become very common. This and Other mature markets, such as automotive lighting, differ from general lighting in some key areas," said van den Berg.
Large-scale production of televisions or cars, select a product that meets the application requirements LED. Therefore, the LED product will be a single type of product, which is convenient for mass production. In other words there is no nuance. Millions of TVs or cars use almost the same equipment. However, in the field of general lighting, different types of application requirements, whether it is work lights, houses, offices or street lights, will be very different, making LED light sources in this area can not be a universal product.
The specific application environment also fundamentally affected the application of LED lighting in the commercial field. Van den Berg exemplifies an Italian Alps tunnel that may use LED lighting solutions. Because the lights of the tunnel need to be on, the return on investment is very fast, even with huge renovation costs. By contrast, office lighting has so far proved to be a very difficult market. This is partly due to the fact that T-5 fluorescent lamps are a very efficient and inexpensive product.
In the retail industry, the demand is also different. With the emphasis on light and color quality, it is increasingly important to give the best CRI for each lighting application. In this regard, halogen lamps are the main competitors for LED lamps, not fluorescent lamps. Retailers also want to see their products "shining" under the perfect light, while doubting whether LEDs can do this. While changing the domestic light bulb, van den Berg believes that when the replacement bulb price is 10 US dollars, it can realize large-scale application without sudden stimuli. The current typical price is 40 US dollars.
For outdoor lighting, such as street lights, LED lighting has been extensively enabled. However, van den Berg still believes that the period of return on investment is too long, and the return on investment must be less than 3 years by increasing efficiency and reducing costs. Only in this way can we truly realize large-scale application.
Obviously, the "general lighting market" is actually composed of many different markets, and the demand points are different. Of course, the cost requirements are the same. LED lighting has more potential than traditional lighting.
The success of the retail sector to open the road to success in the retail sector LED company is Puri. The California-based chip maker provided LED products to the Austrian sports/fashion chain Intersport in December 2010 for lighting throughout the store. According to Tom van den Bussche, Marketing Director of Puri Europe, the versatility of the new lighting technology means that it can guide store shoppers more effectively. This is a classic "value added" case. Van den Bussche also stated that the five chain stores are being remodeled in similar fashion. Such development may lead to LED lighting in hundreds of stores throughout Europe in the short term.
Another obvious advantage of LED lighting is that LED lights do not emit ultraviolet light. The ultraviolet light emitted from traditional halogen or fluorescent lamps will fade the textile for a long time. If clothing is displayed under strong lighting, it will degrade quickly. Similarly, using LEDs to illuminate foods will keep freshness longer, thus avoiding heat from traditional lamps.
Bob Pollock, Cree's vice president of sales, agrees with van den Berg about the difference between a TV LED backlight and a home LED. To this end, he said: "We need different types of LEDs." Bob Pollock estimated that in 2010, the cost of cold white LED packaging only fell to 10% of the price in 2005. By the end of this year it is expected to drop to 33%. However, that is only for the luminaire with 6000K color temperature.
What consumers actually want to buy is warm white lamps. In 2007, Cree's original CR6 downlight was considered to replace the 60-watt light bulb. With about 42 red and white LED combinations to achieve a variety of "color", only consume 12 watts can emit 650 lumens of light. But its cost is even more than $100 for wholesale prices.
In 2010, Cree introduced CR6 replacement lamps, using only 8 LED chips, and the same output only consumed 10.5W. But even if the cost of the lamp is about $50, the cost of the purchase will drop a lot. In some countries, such as the United States, the cost of utility-subsidized purchases is only $20, which is close to the $10 “critical point†mentioned by van den Berg.
Bob Pollock believes that the main market for Cree LED lamps is the popular MR-16 halogen replacement amateur. However, prior to the introduction of MT-G products earlier this year by Cree, none of the LED lamp replacement products had a lighting quality close to that of the MR-16. Bob Pollock expects this product to be successful with consumer acceptance.
Samsung's threatened the LED market is changing, the traditional giants are all aware. They know that Samsung has been following closely. And after Samsung, it will be a Chinese competitive enterprise.
In the face of a downturn in the market, investors are certainly in desperation. Cree's stock price has continued to decline for 52 weeks and will be a warning sign for Philips lighting business. More people will doubt the timing of OSRAM’s initial public offering.
At the same time, Samsung cooperated with other companies to establish an operation center in the United States and publicly announced that it was chasing the American lighting market. OSRAM responded by filing a patent infringement suit against Samsung, and Samsung Electronics’ counter-claims are also necessary.
The flames of war in the LED market will continue, and all the emphasis will be on improving the quality of warm white while reducing costs. Samsung currently has a slight cost advantage. However, how long will Samsung's mass production last? The revolution in solid-state lighting has begun.
