<p><P>PROBLEM TO BE SOLVED: To provide a light-emitting diode lighting device which can perform lighting control of a light-emitting diode stably, and to provide a lighting fixture. <P>SOLUTION: The light-emitting diode lighting device includes a light-emitting diode, a power supply circuit, and a lighting control unit. The power supply circuit converts the power supplied from a power supply into a DC power being supplied to the light-emitting diode. The lighting control unit controls the output current from the power supply circuit to a constant current value corresponding to a lighting control signal when the output voltage from the power supply circuit is lower than a first voltage corresponding to the lighting control signal, otherwise reduces the output current when the output voltage increases. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
