Why China May Not Take Over LED Lighting Just Yet
China became the dominant player in solar modules in a few short years because of standardized manufacturing recipes, a diverse supply chain and high demand.
Now, several Chinese companies have begun to crank out solid staHe said that a county council employee had witnessed a near miss between led lamp a car and cyclist, and he added: "If the argument is leave them off for good, then the answer is ‘no'."te lights. Still, history may not repeat itself in exactly the same way, says Aldo Kamper, CEO of Osram Opto Semiconductors, the chip and LED division of the multibillion-dollar Osram empire, in an interview with Greentech Media.
Part of reason is epi, or the epitaxial growth of films. LEDs are built from precise layers on a sapphire substrate.
“It’s somewhat of an art. You can’t make decent stuff without epitaxial active layers,” he said. “Every machine has its own identity. You need R&D."
“There is still a technology gap and a large quality gap,” Kamper added. “It is not so easy to catch up.CALLS have been made to turn off the lights at one of led lighting Oxford's busiest junctions, after the traffic ran more smoothly when they failed.”
The technology gap, in fact, has already emerged on a few occasions, he said.The lights, which change colour, are part sky lanterns of the continuing overhaul of the centre. Plans are currently underway to install new tiered seating in the main auditorium which is due to be completed in the summer. Kamper says he has heard of some cities and agencies in China swapping out Chinese-made streetlights for lights from more established manufacturers because of technical issues.
Some Chinese fixture vendors, in fact, have begun to advertise that their lamps employ LEDs from Osram and other vendors as a selling point."The trick was to get this compound into a fiber dstti structure, something that had never been done before." Using an innovative high-pressure chemical-deposition technique developed by Justin Sparks, a graduate student in the Department of Chemistry, Badding and his team deposited zinc selenide waveguiding cores inside of silica glass capillaries to form the new class of optical fibers. “For them, that is the badge of quality that they can go to their local government with,” he said.
How the LED story plays out in China is perhaps the most crucial question facing the solid state lighting industry. The solar industry didn’t expect to be colonized quickly, but factory equipment makers and suppliers helped eliminate a lot of the mystery in the industry. China’s remarkable pipeline of grad students and scientific talent, a crucial ingredient in its rise in solar, will likely come in handy in lighting, too.
Other things on Kamper’s mind:
--Supply is rising. “Last year and the year before, there were some shortages, but that is easing up,Corrine Grimley Evans, a spokesman for the Oxford Pedestrians cfl bulbs Association, said the county council's plans for a redesign involving roundabouts would improve life for those on foot.” he said. “With the aggressive nature of the investments that we and others are taking I would not see a shortage of supply.”
