The invention relates to a wide-area lamp and consists of a transparent mounting plate with conducting path structure on which a large number of luminescent semiconductor elements connected to the conducting path structure are mounted in a wide-area spread. Each semiconductor element is surrounded by a reflector, with these reflectors being arranged on the mounting plate and reflecting through the mounting plate the light emitted by the semiconductor elements.
