Will LED-backlit LCD TVs Break into Mass Market?

LED-backlit LCD TVs, enabled by Dolby Laboratories' High Dynamic Range (HDR) technology, produce stunningly clear pictures. Unclear, though, is how much consumers will have to pay for that kind of picture quality. "These products have been screaming to get out to a mass market," said Eric Haruki, research director for TV markets and technologies at IDC. But he cautioned that unless LED manufacturers can achieve the economies of scale and cut the cost of LEDs, "this could still remain a great white hope for awhile."

LED Ring Light For Compact Digicams

Marumi's little ring-light uses LEDs instead of a flash tube, which has a couple of advantages. You can preview the light's effect on the image, and batteries will last a lot longer. Digital photography means that the color of light doesn't matter nearly as much as it did with film, but mixed lighting can still cause problems. The LEDs on the Marumi are daylight balanced.

Factors Influencing Luminous Efficacy of WLEDs

Currently, the luminous efficacy of power LEDs is around 50lm/W (lumens/watt), which does not meet the requirements for home lighting. Therefore, many problems remain to be tackled to boost the power WLEDs (White LEDs) into home lighting, of which the luminous efficacy is the key factor. Although there are many factors which can influence the luminous efficacy of WLEDs, the following ones are worth paying attention to.

Five Problems Concerning White LED Lights

1. Bad Color RenderingCurrently, a white LED produced from a blue LED covered with yellow phosphor generally has bad color rendering (below 80%), as the emitted light lacks red and does not restore this color correctly. But a TL tube or a compact fluorescent lamp may have color rendering indices from 80% to more than 90%.
