when five LED modules were needed for the headlight

It is know that LED light bulbs are to be treated for heat dissipation and to have uniform lighting. Solution from LIQUIDLEDS is to use “liquid” in LIQUIDLEDS LED light bulbs.  With the technology of Liquid Immersed Thermal Management Solution, the liquid not only acts as an excellent medium for heat dissipation of light bulbs but also helps reshaping the luminosity in the beam angle as well as uniform lighting of the light bulbs.LED lights are designed for stylish architectural led high bay light or for landscape lighting, as well as spot lighting points of attraction or for public lighting as needed. The LED light unit has a mounting bracket so it can be secured with bolts anywhere it is needed.The white LED modules used in the two units were manufactured by Nichia Kagaku Kogyo KK and consist of four elements. The modules were also used in the LED headlight of the Toyota’s "RX450h", which was released in April 2009, according to Koito Seisakusho.

Seisakusho used LED headlights for the first time in the world on Toyota's "Lexus LS600h" in May 2007, when five LED modules were needed for the headlight. Now, due to the improved LED efficiency, the number of LED modules needed for the LED headlight for the new Prius has been reduced to three.The two headlights mounted on the new Prius are 66W, slightly more than 30% lower compared with 100W of the headlights of the LS600h, according to Koito Seisakusho.In recent months, Samsung and other LCD TV manufacturers have actively promoted LED-backlit models and hence thirsted for blue LED chips. At present, Samsung has booked large portions of Epistar and Formosa Epitaxy`s capacity to secure supply of the components, which has driven the two Taiwanese LED chipmakers to boost outputs.

Epistar says it plans to outsource some capacity as well as introduce MOCVD (metal organic chemical vapor deposition) to loosen its production lines, and will expand its in-house downstream production capacity, in an effort to boost its existing output of 1.1 million LED chips to 1.4 million units by the end of this year.Formosa Epitaxy has invested a total of US$4.5 million in capacity expansion this year, after the plan to raise capitalization of its plant in Shandong, northern China by US$3 million recently. The firm will expand its laser engraving lines before setting up new epitaxial wafer production lines.

The specialty crop industry plays an enormously important part in American agriculture

The USDA Specialty Crops Research Initiative Award will include $2.44 million from the USDA and an equal amount of in-kind contributions of equipment and services from industry partners. The project is titled "Developing LED Linear high bay light Technology and Practices for Sustainable Specialty-Crop Production." Merrigan pointed out that” The specialty crop industry plays an enormously important part in American agriculture and is valued at approximately $50 billion every year. These projects will be key to providing specialty crop producers with the information and tools they need to successfully grow, process, and market safe and high-quality products." In the process of the project, Mitchell will test led high bay light on high-wire tomatoes. He believes that using LED lights on the sides of plants will increase photosynthesis and flowering, improving yield. Roberto Lopez, an assistant professor of horticulture, will work with about 20 species of bedding pla...

We expect global sales to be about 60 percent of YAHAM going forward

Rice has served customers, built partnerships and done deals around the world for more than 20 years.He will be responsible for all non-U.S. markets with particular emphasis on high-growth markets such as China, India, the Middle East and Brazil where he will accelerate LED Linear high bay light efforts to meet customer needs with GE’s leading technology and services. In many of these markets, this includes GE’s “company to country” growth strategy in which GE works directly with governments to meet local needs. According to GE Chairman and CEO Jeff Immelt, “We expect global sales to be about 60 percent of GE going forward. Our global growth has expanded by about 15 percent a year for most of the past decade and we expect it to continue in the future,” Rice will oversee 12 integrated local organizations that will include business development, commercial teams, finance, led high bay light controllership and legal. This will include China, India, Southeast Asia, Latin/South America,...

Only imaginations brought the ceremony

In 1923, families gathered around the radio to listen as President Calvin Coolidge lit the first National Christmas Tree. Only imaginations brought the ceremony, and the tree located in what is now President’s led linear high bay light , to life. Eighty-nine years later, families are still gathering to witness the lighting of the National Christmas Tree, but 21st century technology is giving them a front-row seat. At 4:30 p.m. ET on Dec. 1, GE Lighting, in conjunction with the National Park Foundation, an official charitable partner of America’s national parks and the National Park Service, invites families to gather around the laptop to watch as the National Christmas Tree come to life. GE Lighting has been designing the National Christmas Tree, and contributing its lighting and decorations for 49 years.  The design process usually begins only a few months after the previous year’s lighting on the National Christmas Tree is shut off, often starting in March or earlier. Thoug...
