That kind of yellow paint is very sensitive to green and blue. I would advise museums not to use LED bulbs any more as they emit at lot of blue light.” The researchers used powerful x-rays to examine a series of paintings by Van Gogh. "We discovered that the Dutch master didn’t always use the same type of chrome-yellow paint. ”
Van Gogh also used a lighter lemon-yellow and a lighter-still primula-yellow. "These varieties have a different crystal structure, albeit combined with higher sulphur content. They react quiet adversely to light rays. After just a few days of our tests they changed colour from to brown and olive green. We discovered this unstable form of chrome yellow paint in a number of very well-known paintings like the 'Portrait of Gauguin” and the ‘Sunflowers’.
Beth Rundlett of DSM and committee co-chair, said that ,“UV LED technology has the potential to play an essential role in radiation curing industrial applications, RadTech’s technical efforts will further promote UV LED development and it's full integration into everyday industrial processes.”

US chipmaker Marvell Technology faces having to pay one of the biggest ever patent damage awards. A jury in Pittsburgh found the firm guilty of infringing two hard disk innovations owned by local university Carnegie Mellon. It said Marvell should pay US$1.17 billion in compensation—however, that sum could be multiplied up to three times by the judge because the jury had also said the act had been “wilful.”
Marvell’s shares fell more than ten per cent. The maximum penalty would be close to the $3.96bn value of the company, based on its market capitalisation. Marvell told the it would try to convince the judge to reverse the judgement, and would appeal if that failed.
The university’s law firm issued a statement saying it took “pride” in securing the award following Marvell’s failure to license the university’s intellectual property. Marvell makes a range of chips which includes processors which power devices including Blackberry smartphones, Sony Google TV internet video boxes and LED lighting controllers, as well as hard disks.

Spark will undertake all the light fixing for the above tunnels
It is reported that Ganchong Highway is not only a major thoroughfare connecting southeast coastal area and southwest in China, but also the most difficult highway constructed in Jiangxi Province so far with the biggest ratio of bridges to tunnels.
This tunnel for electromechanical system lighting is composed of JD3 and JD4 phrases, involving 12 tunnels: Luota, Gankeng, Jianfengling, Chatan, Dafuwan, Gaosheng, Chongyi, Xiaguangdong, Xiaguangxi, Tianxin, Guangtian and Wenying. Spark will undertake all the light fixing for the above tunnels. This light project will be completed in December.
SPARK, considering the tunnels’ condition, takes various measures to meet its illumination requirement by adjusting lighting parameter and trying different luminaries.The luminaries applied in this project, including LED tunnel light, LED street light and other lights, are characterized with exquisite appearance, soft light, instant start, no glare and no strobe, which reduces people’s visual fatigue and distraction. The highly accurate constant currency driver guarantees the safety, extends the luminaries’ life and certainly reduces its maintenance expense.
The LED luminaries from SPARK have all kinds of advantages, such as, high uniformity ratio of illumination, high luminous efficiency, low light decay, homogeneity and stability. The product life is over 50,000 hours with an electricity-saving rate of 70%.This project is significant not only in the transportation safety of Ganchong highway, but also strongly effects on the development of the national semiconductor light industry and energy-saving.
Eight companies have been selected under a San Francisco Public Utilities Commission pilot program, and they will each receive a $15,000 stipend to demonstrate what their wireless streetlight systems can do. The technology will be tested in the Sunset, Presidio Heights and downtown neighborhoods.

LED lighting suppliers are making their products more affordable
This will encourage local LED manufacturers to compete for public works projects. Since industrial standards for LED lighting have not yet been finalized, the PIDA urges local governments to carry out strict inspection of LED streetlights to ensure quality.
Another happy development is that LED-lighting suppliers are making their products more affordable, and are making them available both at brick and mortar stores and on the Internet.
However, consumers have been left confused by the inconsistency of specifications defined by suppliers of 6-12W cool white LED bulbs used as 40-60W incandescent replacements. For instance, LED bulbs designed to replace 60W incandescent bulbs have been labeled by different suppliers with incandescent lumen ratings ranging from 420 to 810.

The same time improve electrical efficiency by alleviating problems of light trapped or lost in an LED chip
Another core technology in which Epistar excels is bonding technology that provides for flexibility in epi structure substrate selection. Epistar’s RD team has developed various bonding techniques with metal, glue, and dielectric materials so that the epi structure is not limited by its growth substrate anymore. Taking GaN-on-Si as an example, after nitride is grown on Si substrate, the epi can be transferred to a transparent or reflective carrier by bonding technology to avoid the light from being absorbed by opaque Si. In other applications, multiple LED structures with different light color can be bonded to one common substrate. With different bonding materials, LED can be disposed on different carriers depending on the application. For example, a widely-adopted low temperature metal bonding process provides robust mechanical support with optional reflector for light extraction enhancement, which makes a vertical blue LED possible at lower cost. Epistar’s innovative glue or dielectric bonding provides a transparent interface that provides the LED with the advantages of having stronger support and transparency, which is expected to be particularly useful in general lighting and LED display applications. Epistar has successfully obtained patents in this technology around the world, including in China, Japan, Korea, Taiwan, and the United States.
For applications requiring high power, a larger size chip is normally preferred because it endures high current injection with high power efficiency. Epistar has acquired a portfolio of patents from a Swiss company directed to technology including the design of extension electrodes that can avoid the high cost associated with the process and at the same time improve electrical efficiency by alleviating problems of light trapped or lost in an LED chip.
As the first company to commercialize high-voltage chips (HV), Epistar has also developed several arrangements of multiple cells/junctions on one common substrate that can be driven by high voltage. With its delicate interconnection design, HV chips have excellent electrical properties and flexibility for diversified lighting applications. In addition to such unique structure, Epistar is known as the only chip maker that can provide full-spectrum products. As a result, Epistar can help customers by using its excellent red and blue chips with one or more cells/junctions for warm white applications. Design patents and utility patents related to this technology have been granted to Epistar in countries around the world including China, Japan, Korea, Taiwan, and the United States.
Epistar’s RD team is full of energy and has a vision for the future. There are already several ready-to-go technologies in the patent portfolio that can embrace the LED lighting era to come. One representative work is to connect chips on one transparent base to form a filament-like structure for retrofit light bulbs or lamps. In addition, Epistar also obtained exclusive rights in remote phosphor field that contains an optical device in-between a wavelength converting device and an illumination source. With these patented technologies, Epistar can work with its customers to develop more competitive products and speed up the adoption of LEDs in lighting.
