Beschreibung
Zusammenfassung:	An electronic flash, imaging device and method for producing a flash of light having a wavelength spectrum in the visible wavelength range and the infrared wavelength range uses a fluorescent material to convert at least some of the original light emitted from one or more light sources of the electronic flash to longer wavelength light to produce the flash of light. The light sources may be configured to generate light having a peak wavelength in an ultraviolet-and-visible wavelength range. The fluorescent material may include any combination of red, green, blue and yellow phosphors.
