ELECTRONIC FLASH, IMAGING DEVICE AND METHOD FOR PRODUCING A FLASH OF LIGHT HAVING A WAVELENGTH SPECTRUM IN THE VISIBLE RANGE AND THE INFRARED RANGE USING A FLUORESCENT MATERIAL

摘要

visible light wavelength range and an infrared wavelength range of the wavelength spectrum of the generation of the electronic flash having a flash photographing device and the method is converted into light of a longer wavelength emitted from the light source at least a portion of one or more of the electronic flash light by using a fluorescent substance that generates a flash . The light source may be configured to generate light having a peak wavelength in the UV and visible light wavelength range . The fluorescent material may include any combination of the red, green, blue, and yellow phosphor .
