<P>PROBLEM TO BE SOLVED: To provide a lighting fixture capable of inhibiting thermal effects among light sources and attaining resources savings by making it more compact. <P>SOLUTION: When a detected temperature by a thermal sensor reaches the predetermined temperature or exceeds the predetermined temperature, a control circuit modulates lighting so that an applied voltage to light emitting diodes 18B is lower than an applied voltage to light emitting diodes 18A. This enables to lower a heating value at the light emitting diodes 18B, thus reducing a thermal effect on the adjacent light emitting diodes 18A. <P>COPYRIGHT: (C)2007,JPO&INPIT |
