- The LED color change system was first calibrated at a fixed temperature by adjusting four driving currents for red, green, blue, and white LEDs. The KONICA MINOLTA CL-200 colorimeter was used to test the color coordinates and illuminance of the achieved color.
- The PWM duty cycles can be obtained using a linear relationship between the illuminance and duty cycle [5]. The proposed LED lighting is based on four kinds of colors, red, green, blue, and white. The color temperature change algorithm is achieved by the following equation.
- The proposed system adjusts the light intensity of each LEDs to achieve a required color. Fig.
- This paper proposed an emotional LED lighting system with a color temperature change algorithm. The system can directly control the LED color with independently changeable illuminance.
