Lens-mounted LED flash rings are a great resource for properly lit macro shots, but they’re usually pretty expensive (think $150). Enter Brando’s budget version.

It’s almost certainly crappier than the full-priced models, as is Brando’s wont, but hey, at $58 I’m perfectly willing to accept a few deficiencies. It can light up in either the full circle or a semicircle on either side, and is powered by 2 AA batteries. Pretty solid deal for something that usually seems unnecessarily pricey.

Nanosys offers better saturation of LED-backlit displays with nanoscale coating

In: gadgets

While we all wait around for larger-sized OLED displays to become feasible for the consumer market, Nanosys has stolen in and demonstrated a new LED coating technique that proposes to radically improve color saturation in LED-backlit screens. Based on standard blue LEDs — the most efficient kind — this works by applying nanoparticles to the light and thereby endowing it with the desired hue. While the nano-coating can make standalone LED lights far richer in color, the real potential is in its deployment in LED-backlit displays, such as those becoming dominant on laptops today. By employing a coated array of blue LEDs instead of the standard white stuff, this can deliver greater color saturation while fitting within the same energy profile of current LED tech. Products boasting Nanosys’ new hotness are said to be coming out later this year, with some appropriate premium slapped on the price for the fancier output.

Nanotechnology Could Vastly Improve The Color Of LED Lighting [Led]

In: gadgets

12 Jan 2010

I switched to LED lights on my Christmas tree this year and, while generally pleased, there is no doubt that the colors are a bit “off.” A simple nanotech coating could change that by making colors brighter and warmer.

Nanosys is the company behind this new approach, and the process is fairly simple: a phospor material developed from nanomaterials is layered over standard blue LEDs (the most energy-efficient color) to create a spectrum of colors that are warmer and more vivid. So, unlike other methods (quantum dots for example), Nanosys hasn’t tried to reinvent the wheel. Manufacturers could simply apply the coating without having to start over with a completely new product.

Furthermore, Nanosys’ material could be utilized in a lot more than just light fixtures. Think about laptop and HDTV displays with better, brighter screens—all without increasing energy consumption. [Treehugger via DVICE]
