Efficient High Power Flash Light

Although the xenon lamps dominate the standard camera market, they are not applicable in the portable phone. As a matter of fact, the large reservoir capacitor and high voltage associated with the xenon Flash make such a concept not suitable for the cellular phone equipments. MMBF0201NLT1 MMBF0201NLT1 MMBF2201NT1 NTA4001NT1 MMFT960T1 The semiconductor based White LED devices provide the right choice when limited Flash light becomes necessary to illuminate a photographic scene. This paper depicts the basics of the xenon concept and details a typical White LED Flash application.
