초록
This paper proposes a multi-color lamp using ROB LEDs for color variation. The lamp has an internal controller circuit. so it can be directly connected to the existing incandescent lamp socket. It's main body is comprised of two PCB layers. The upper layer contains 44 LEDs and the lower one has a simple microcontroller-based PWM control circuit. Appropriate number of RGB LEDs are so chosen according to the color mixing theory that the overall LEDs represent a color temperature of 6500K. The lamp has functions of both ON/OFF control and PWM control, so is capable of color variation of over 100,000 colors and of more than 10 patterns.
