Prices of LED light bulbs showed a slight decline this August, according to the latest reporting from LEDinside, a division of TrendForce. Compared with July, the global ASP of 40-watt equivalent LED light bulbs fell by 1.1% to US$6.4, while the global ASP of 60-watt equivalent LED light bulbs dropped by 1.5% to US$7.7. LEDinside analyst Allen Yu pointed out that Japan witnessed a larger price decline as the promotional pricing of new products including LED filament bulbs helped pull down ...

With their research on nanomaterials for optoelectronics, scientists from Heidelberg University and the University of St Andrews (Scotland) have succeeded for the first time to demonstrate a strong interaction of light and matter in semiconducting carbon nanotubes. Such strong light-matter coupling is an important step towards realizing new light sources, such as electrically pumped lasers based on organic semiconductors. They would be, amongst other things, important for applications in telecommunications. These results are the outcome of a cooperation between Prof. Dr Jana Zaumseil (Heidelberg) and Prof. Dr Malte Gather (St Andrews), and have been published in “Nature Communications”.

How many researchers does it take to change a light bulb? And how many lives could they save by changing it?

A breakthrough by a team of researchers from UCLA, Columbia University and other institutions could lead to the more precise transfer of information in computer chips, as well as new types of optical materials for light emission and lasers.
