LEDs used in mobile phone cameras have been shown once again to provide a better light source than other components.<br/><br/>A study by thin-form supercapacitor developer CAP-XX indicates that LEDs provide more light energy than most xenon flashes suitable for five-megapixel slim camera phones and digital cameras.<br/><br/>A previous study by the firm had compared the impact of the components in 1.3-3.2-megapixel devices.<br/><br/>Commenting on the findings, CAP-XX vice-president of applications engineering Pierre Mars explained: "People often wrongly assume that light power, which is the brightness or intensity of the flash, is the key because it's what draws our attention, but it's really the light energy that counts."<br/><br/>Xenon flash tests used SonyEricsson, Nokia and Samsung phone models, while standard battery-powered LEDs were tested using the Nokia N73 and N96 models.<br/><br/>Supercapacitor-powered LEDs were tested using a two-LED array of Philips Luxeon PWM4s at 2A each.<br/><br/>Earlier this year, the company tested surface mountable supercapacitors using working prototypes in order to test their suitability for mass assembly production.<br/>!http://feeds.directnews.co.uk/feedtrack/justcopyright.gif?feedid=1785&itemid=19378288|alt=ADNFCR-1785-ID-19378288-ADNFCR|src=http://feeds.directnews.co.uk/feedtrack/justcopyright.gif?feedid=1785&itemid=19378288!
