A flash emitter includes a flash discharge tube, a reflector and a transparent protector. A light reducing plate is set in front of the flash emitter. The light reducing plate is provided with a slit located in front of a center of the long flash discharge tube, and the slit is extended in a direction perpendicular to the longitudinal direction of the flash discharge tube. The slit provides a good light distribution of flash light and reduces light to prevent overexposure of a main subject.
