<p>PROBLEM TO BE SOLVED: To provide an illuminating device for an LED capable of being substituted for a halogen light bulb by a simple configuration.SOLUTION: An illuminating device that can perform dimming depending on a drive signal supplied from exterior, comprises: at least one first light-emitting device that has a semiconductor light-emitting element having a light-emission peak wavelength at 360 nm or more and 480 nm or less, and that emits white light of a first color temperature; at least one second light-emitting device that emits white light of a second color temperature higher than the first color temperature; and a current controller controlling a drive current to be supplied to the first light-emitting device to a constant value, and controlling a drive current to be supplied to the second light-emitting device by a variable current depending on the drive signal, in a time period where the drive signal is supplied.</p> |
