LED will accelerate the penetration of the lighting market this year. International brand manufacturers Philips, Cree, and Samsung have successively released LED bulbs with a price of only half of the current market price, announcing the official arrival of the LED lighting era. At present, LED has begun to expand its penetration from the commercial lighting market, and will significantly replace incandescent light bulbs in the next few years, becoming the mainstream light source for home lighting.
After Samsung and Cree released LED light bulbs for less than $15 and $10 respectively, OSRAM also announced that it will launch 10 euros (about $13.1) in June this year. The following products will make the price competition in the LED bulb market more and more fierce, which will help stimulate consumers' willingness to purchase and push up the market penetration of LED bulbs.
NPDDisplaySearch analyst Yan Qingwei said that the penetration rate of the overall LED lighting market depends on the brightness and price ratio of each bulb (lm/$), so the brand factory is moving towards increasing the brightness of LEDs and lowering the unit price to speed up the penetration of LED bulbs. The speed of the lighting market; while Cree's announcement of new products represents a turning point in the LED lighting market.
It is understood that Cree's replacement of a 60-watt (W) incandescent lamp can deliver 800 lumens (lm) of brightness at 9.5 watts for $12.97, while a 40-watt incandescent lamp can consume 6 watts. It emits 450 lumens and is priced at $9.97.
Not only that, but Cree uses LEDFilamentTowerTechnology and a well-balanced light source in the glass cover to provide a lighting experience comparable to traditional incandescent bulbs with a lifespan of at least 25,000 hours, twenty-five times the traditional solution. .
Not to let Cree specialize in the past, OSRAM also announced that it will start selling LEDs with a price of less than 10 euros in place of 40-watt incandescent bulbs in Germany in June, while most of the current LED schemes in Europe are higher than 15 euros. At the same time, during the promotion period, the replacement of 60-watt incandescent lamps will also be less than 10 euros, and the life expectancy is as long as 15 years.
In fact, as early as December last year, Samsung has released a 60-watt Retrofit LED bulb for US$15 in the US market, and Cree and OSRAM’s price cuts this year have helped people buy LED bulbs. The willingness to replace incandescent bulbs.
In addition to the price of LED bulbs fell to sweet spots, LED bulbs also have a breakthrough in brightness. According to Yan Qingwei, the current mainstream specification of the bulb market is still 660 lumens, but the high-lumen light bulb is about to become more and more popular. Among them, the 900-lumen LED bulb specification is the most popular.
Yan Qingwei pointed out that with the gradual increase of LED lamp penetration rate, the overall lighting market output value in the fourth quarter of 2012 has reached 5.64 billion US dollars, and is expected to reach 6.89 billion US dollars in the first quarter of 2013.
It is worth noting that in many LED lighting applications, especially the most anticipated commercial lighting applications, it will become the hottest development field this year.
Commercial applications take the lead in fermenting LEDs to accelerate the penetration of the lighting market. LEDs in the commercial lighting applications have high energy-saving benefits, and can significantly reduce maintenance costs, coupled with incentives from national governments, have attracted many companies to start mass import, not only become LED-related supplies The primary market for active business attack is also the most important source of power for the growth of LED lighting market in the next few years.
Tony Armstrong, director of product marketing at Linear Technology's Power Products Division, said that LED lighting production in 2012 was $12.5 billion, accounting for only 16 of the overall LED application market, still below the two major applications of mobile devices and TV backlights. However, starting this year, LED bulbs will have multiple advantages such as power saving, longevity and high brightness, and accelerate the penetration of commercial lighting and home lighting.
Armstrong quoted the market research report as saying that the current price of LED bulbs is still not ideal for home lighting customers, so the main growth comes from commercial lighting. In addition to the long-term cost-effectiveness of LED bulbs, the government's tax reduction offers, such as South Korea. The government's tax cuts for private companies using LED lighting products are also an important incentive to accelerate the development of LED lighting products in commercial applications such as parking lots, offices, factories and warehouses.
In fact, because commercial lighting consumes as much as 25 to 40 of the building's power consumption, the use of LED bulbs to replace incandescent bulbs has become a way for business owners to save on electricity bills. Armstrong pointed out that LED bulbs have a long service life, and companies can reduce the frequency of lamp replacement, saving maintenance costs and labor costs. For example, the replacement cost of High BayLighting is very high.
KCCheng, Asia-Pacific marketing director of Osram OptoSemiconductors, said that there are two major trends in the commercial lighting market that are affecting the product design direction of component suppliers. One is that LED chips must be miniaturized to meet special luminaire designs. For example, many office or hotel halls, and even museum lighting, require the use of panel luminaires (PanelLuminaire) or linear retrofits (LinearRetrofit), which do not individually illuminate, but present a complete light source concept. Therefore, LED chips must conform to this trend to reduce the size, allowing the luminaire to place more LED light sources in a limited luminaire space.
Cheng further added that in addition to LED chip miniaturization, high-power LED chips have recently become more and more popular in the commercial lighting market, which can convert 1 to 2 watts of power and provide high luminous flux (LuminousFlux). Take OSRAM's LED chips as an example. It achieves 290 lumens (lm) brightness at 700 milliamps (mA) and 250 lumens in harsh environments at 85 °C.
Armstrong pointed out that after comprehensive research reports, the LED home lighting market will start to take off this year, and as LED bulbs gradually gain a foothold in the commercial lighting market, the price of LED lamp housings will further decline, when LED bulbs will More intimate prices attract more families to adopt; in the next few years, the market's revenue scale is expected to show explosive growth like the commercial lighting market.
According to the research report of the strategy group StrategiesUnlimited, the revenue growth of LED bulbs for commercial lighting from 2011 to 2012 is as high as 76, especially in the Japanese market. However, the growth of the region will slow down this year, but other regional markets will begin. A large number of LED lights are used as light sources for commercial lighting applications, and the output value of the LED lighting market continues to rise.
Grab the commercial lighting LED brand factory to improve the component outsourcing rate In response to the development challenges of commercial lighting products, the international LED lighting brand manufacturers continue to expand the market share, and also began to adjust the original one-stop production strategy. Philips, singular (GE) and Cree have begun to increase the proportion of LED bulb components outsourcing, and want to develop electronically dimmable LED commercial lighting solutions by electronic control (Electronic ControlGear, ECG) manufacturers to reduce R&D costs and shorten product development. Cycle to continue to expand the market share in the commercial lighting application market.
Zhang Wengui, senior manager of Infineon's Power Management and Diversified Electronics Division, said that the traditional lighting product manufacturer Philips, which took two years from the conversion of T8 tubes to T5 tubes, took five years to complete. Standardize the T5 tube. However, after the LED bulb market, the product development timeline was reduced to 8 months, which forced Philips to seek R&D cooperation opportunities from ECG plants outside the original supply chain in response to market changes.
Zhang Wengui further pointed out that despite the huge market demand for consumer and household LED bulbs, the price competition is fierce and the output value has not increased significantly. Therefore, major component manufacturers will focus on the commercial lighting market in the next few years due to their higher output value. According to market demand, we can adjust the product's temperature range, lightning protection and other specifications, cut into the outdoor lighting market, or extend down to the home lighting application market.
However, commercial lighting products pay more attention to dimming characteristics than home lighting solutions. In addition to the brightness adjustment function, more importantly, with the changes in the environment and application fields, commercial lighting bulbs must produce high color rendering with color mixing technology ( ColorRenderingIndex) has a color temperature change, but this feature allows brand manufacturers to spend more time designing the internal structure of the LED bulb.
Under the pressure of limited product development time, the LED bulb brand factory has begun to expand cooperation with external component suppliers, and together with electronic controller manufacturers to jointly develop a new generation of commercial lighting products, thereby shortening the development time and adding to its LED bulbs. More professional dimming function.
Zhang Wengui pointed out that major brand factories have begun to use the luminaires to go upstream to the control system or power system field, to find suitable partners to strengthen the supply chain cooperation relationship and make up for their own insufficient R&D resources, while the upstream component manufacturers also Start visiting vendors and launch related products after understanding customer needs.
Zhang Wengui pointed out that Philips, Osram and Cree each released LED bulbs in the price range of 10 to 15 US dollars, representing the LED lighting market has been in the lead period of the previous 5 years, will enter the penetration period from this year, and even emphasize the difference of LED products. The third stage of development.
In fact, international brand manufacturers must not only improve the degree of product differentiation, but more importantly, major manufacturers must further highlight the power-saving characteristics of their LED lamps in response to increasingly stringent energy regulations. One of the major practices is to adopt LEDs. The function of lamp daylight sensing and autonomous dimming attracts consumers' attention with the concept of intelligent lighting.
Energy regulations push the smart lighting business opportunities to see the European and American governments in order to improve energy efficiency, have issued a new wave of energy regulations, limit the commercial building and residential electricity consumption, driving the international LED lighting brand manufacturers to increase deployment can adjust the brightness according to the environment The LED lighting solution has thus driven the development of smart lighting.
Sajol Ghoshal, director of the Austrian Microelectronics (AMS) sensor-driven lighting business, said that the United States has offered a new wave of policies to improve energy efficiency, such as the US government's tax subsidy of $20 per square meter to encourage companies to replace lighting systems; California The introduction of the new building regulation "Title24" requires that the lighting power density should be less than 8.6 watts per square meter from this year, while buildings larger than 230 square meters are forced to introduce automatic dimming systems, and manual control is prohibited.
Coincidentally, the EU Energy Directive has also set a 20-20-20 target to reduce greenhouse gas emissions by 20, reduce energy consumption by 20, and increase the proportion of renewable energy by 20.
In view of the fact that the above energy regulations strictly limit the power consumption of enterprises and households, it is difficult to meet the increasingly stringent requirements of simply replacing LED bulbs. Therefore, LED lighting manufacturers have begun to vigorously promote intelligent lighting control systems that can automatically adjust brightness according to the environment, further enhancing The power saving capability of the LED lighting system. Ghoshal pointed out that if the LED bulb can sense the degree of daylight, the LED light from the window to the wall can reduce the brightness of 20~40 in sequence, which will save more than 30 power.
At present, Philips, Osram, Samsung, Singular, and Toshiba have all developed smart lighting products and established The Connected Lighting Alliance to promote the development of the smart lighting market. Among them, Philips cooperated with Apple (Apple) at the end of last year to launch HUE smart light bulbs that can be controlled by wireless local area network (Wi-Fi). Samsung also announced at the International Fair for Lights (Lightfair) held at the end of April this year. In the third quarter of this year, the replacement of light bulbs with ZigBee as the main connection method was started.
According to Philips official data, the global lighting market revenue will reach 90 billion euros in 2020, of which up to 57.4 revenues from LED lighting and control systems will be the most important source of revenue for LED suppliers.
