Philips Lumileds optimistic about the LED Flash Market

The light emitting diode (LED) to attack the flash market opportunities, Philips Lumileds code introduced a new generation of LUXEON Flash series LED products, more emphasis on high brightness and high driving current, is expected to be officially mass production before the end of this year.

Philips Lumileds lighting product manager MichEL Zwanenburg said that the mobile phone has a million pixels camera and represent the general trend of the company's latest publication, LUXEON Flash series LED drive current can reach 1 amp market requirements, and the maximum drive current can be as high as 2.5 amperes.

With thin and million pixel camera mobile phone is popular, with more high brightness LED flash is imperative, therefore, South Korea mobile phone manufacturers have launched LED mobile phone brewing flash photography 1000 Ma drive current, the design of LED flash will face more stringent challenges in the future, in addition to using high brightness and high driving current of LED, Zwanenburg that, at 1000 Ma drive current LED flash scheme, power conversion efficiency and power management for two key design.

In addition, Zwanenburg analysis, the future of high power LED to achieve the purpose of heat dissipation will require greater cooling area, therefore, LED will flash toward the development of large size, but also to take into account the market for LED light source color accuracy and consistency requirements.

Compared with the traditional xenon flash, LED flash in addition to saving energy, thin advantage, fast charging and long time light characteristics, but also its win another major camera mobile phone manufacturers are favored, so the future can support the use of other lighting source mobile phone video, after the potential development of deep potential.
