  • Lighting device
    Patent number: 9137867
    Abstract: The disclosed lighting device gradually adjusts from an incandescent bulb color having a 30% dimming rate to a daylight color having a 100% dimming rate. The overall dimming rate is changed to a linear shape, and the ratio of the dimming rates of the incandescent bulb color and the daylight color is adjusted. When changing from the incandescent bulb color to the daylight color, the color is changed to an intermediate color that mixes the incandescent bulb color and the daylight color, and then ultimately is changed to the daylight color, and so it is possible to change the dimming rate without causing discomfort or annoyance in humans, and a comfortable and natural light environment is achieved.
