<p><P>PROBLEM TO BE SOLVED: To provide a light-emitting unit capable of adjusting easily variations in luminance and color tone in individual light-emitting units and correcting these to have an optimal curvature. <P>SOLUTION: The light-emitting unit is provided with a plurality of light-emitting diodes 23, a first switching element 50a to switch on and off current to be supplied to the light-emitting diodes 23, a DMX receiving means 51 to receive an emission intensity signal from a light control table, a first table 60a to show relations between a duty ratio of the first switching element 50a and the emission intensity signal, a first controller 40a which extracts the duty ratio corresponding to the emission intensity signal from the first table 60a and outputs a drive pulse signal to the first switching element 50a, and a first variable resistor 52a capable of inputting a correction information regarding the luminance of the light-emitting diodes 23. The first controller 40a changes the duty ratio extracted from the first table 60a based on the correction information when the correction information is input. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
