where premium lighting products were displayed in an elegant setting

The president of Diguang, said it was very rewarding to hear so many experts and buyers speak highly of their products during the Hong Kong Lighting Fair. The show also gave their a deeper appreciation for the led high bay light great potential of the entire LED lighting market. Based on their longstanding expertise in the specialty of backlights, they plan on vigorously developing their LED lighting business, as well as their newly launched value-priced mini-notebook product portfolio.

According to market estimates, the total LED market reached $2.8 billion in 2006, with general lighting applications constituting less than 10% of the total. The market for LEDs for general lighting is expected to grow at a compound annual growth rate of 35%, reaching nearly $1.4 billion by 2012. The total high-brightness LED market, including general illumination, automotive headlights and backlights for monitors and TV screens, is expected to reach $8.3 billion in 2010, well over twice the level of 2005.

The 2008 Hong Kong International Lighting Fair, which celebrated its 10th anniversary this year, was 17 per cent larger than last year's edition. It featured more than 1,570 exhibitors from 33 countries, including first-time exhibitors from Romania, the led flood light. Popular theme zones included the Galaxy of Stars, where premium lighting products were displayed in an elegant setting, Crystal Indulgence, resplendent with crystal lighting and chandeliers, and Green Lighting, with a focus on state-of-the-art, energy-efficient and environmentally responsible lighting.

they switch to LEDs across the board

While LED backlighting is a short-term market trend, the market for LED general lighting applications will take off only in the mid-term. Before this application will achieve a major breakthrough, the LED technology has to overcome certain technological hurdles, especially with respect to their efficiency. Pickert pointed out  that the led flood light is not yet fully competitive against sodium discharge lamps and fluorescent lamps in widespread use for street lighting, in ten years it certainly will be the dominant lighting source but we do not expect a strong market demand before 2012/2013. However, what Pickert did not say is that manufacturers of lighting devices such as Germany's Osram or Dutch Lumiled probably intend to exploit the market potential for today's energy saving lamps before they switch to LEDs across the board.

Nevertheless, Pickert does not see LED production overcapacities comparable to the DRAM market since the short- and mid-term growth factors are tangible. He noted "Energy saving is not only popular in Europe. If you take a look to California, you will see great advances towards this direction. For instance, all traffic lights are equipped with LEDs. Also in China, the demand for energy-saving lighting solutions is rising; the Chinese government recently has launched a Solid State Lighting initiative that aims at replacing light bulbs and similar energy hogs by LEDs. All these factors however will create demand only in about three to five years.”

Aixtron claims to control about 70 percent of the global market for Metal Oxide Chemical Vapor Deposition (MOCVD) equipment used to produce III/V semiconductors and thus LEDs. The market volume for this type of led high bay light equipment currently is estimated to about $300 million per year. Aixtron regards US-based Veeco Instruments as its only competitor in international markets; besides Veeco, there are several smaller MOCVD vendors in Japan which however are serving only local markets.

the consumer electronics market

He said the investment was an estimate and details were not yet decided. The investment is in anticipation of a move to the new technology from the now more common liquid crystal displays.OLEDs use light-emitting organic compounds similar to those found in fireflies. TVs using led high bay light panels don't require a backlight and can be made thinner than those based on liquid crystal or plasma displays.

The key to success was a perfectly matched system of optimized chip technology, a highly advanced and extremely efficient light converter and a special high-performance package. By far, Osram has already applied for patents for the technologies that lie behind these records.According to the company's analysis that with high CRI, superior lumens per watt and long life, its new top-view LEDs are poised to dominate the lighting market segments where high-performance light sources are a trend.

According to Scientists, the OLED display, means high-quality images, so it’s difficult to make, but one day could become a display standard for the consumer electronics market. Samsung Electronics will spend 935.8 billion won to acquire 50 percent of the new company, to be named led flood light, and Samsung SDI will spin off its OLED division to form the joint venture in September.According to analysts at the Darnell Group market research firm in Corona, Calif, LED will rapidly accelerate over the next few years in general illumination applications.

LED lighting for outdoor use such as street lamps

In addition to the combination of high brightness, long life and low profile height, Avago's ASMT-Mx00 1W Power LED series also provides a significant advantage in the production environment: They can be easily soldered using conventional surface mount techniques to minimize production costs.Avago's ASMT-Mx00 series LEDs is capable of being driven to a high current of 350 mA to deliver up to 42 lumens output making this product an ideal for use in solid state lighting applications. Moreover, the ASMT-Mx00 series is compatible with IR soldering processes.Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.

The LED lamp is 100% compatible with current sockets (E27) and is similar in appearance to compact fluorescent lamps (CFL) of the same wattage. The lamp is easily installed and readily replaces CFL and incandescent lamps. Advantages of the Delta High Brightness LED Lamp include: power-saving, excellent thermal dissipation & color rendering index (CRI), high efficiency, and long life. Of special note is the lamp's outstanding energy-efficiency, especially at lower environment temperatures. In addition to the 5W/9W/12W LED Lamp, Delta is demonstrating LED lighting for outdoor use such as street lamps and floodlights that is based on the same technology. The show signals Delta's entry into the general LED lighting market.


"In the spirit of Delta's commitment to energy-efficiency, we use superior technology in optical design, thermal modules, key components, and lighting techniques to successfully develop a high brightness LED lamp that has power-saving, excellent thermal dissipation & CRI, high efficiency, and long life. Its performance is much better than traditional lamps and CFLs," said Mr. Sean Chang, director of the CPBG Optical Component Business Unit at Delta. To bring about a better living environment, Delta continues to create exceptional LED products for solid-state lighting solutions.
