More Information
Summary:A LED illuminating device includes: a power source device, a controller, an LED lighting device, and an LED unit 4 incorporating LEDs of a plurality of emission colors. The device is configured to mix the lights of the LEDs at an arbitrary proportion and set the lights in an arbitrary color mixture proportion on the basis of a dimming signal from the controller. The device is further configured so that: a coefficient specific to the LED unit at which an emission color of the LED unit becomes a desired color can be set to a signal value of the controller preliminarily set as a standard. The LED lighting device can control an emission amount of the LEDs having the respective emission colors by using a value calculated by a calculation expression employing the specific coefficient.
