Abstract
A lighting unit for producing flash light toward subjects in a photographic scene comprises an matrix array of light emitting elements arranged so as to have individual lighting fields different from one another, a selective excitation circuit for exciting selectively the light emitting elements so as to produce flash light, different in intensity as appropriate, in predetermined lighting patterns and an excitation/extinction circuit 250 for exciting or extinguishing the light emitting elements. A photographic equipment equipped with the lighting unit has directive switches or buttons for directing the lighting unit to select lighting pattern according to focal lengths, zoom rations, operation modes including a communication mode, and/or demands of pre-lighting,
