A Light-emitting Diode (LED) lighting system with both color and dimming control

Abstract

Researchers have learned that different colour temperature affects users' performance in the settings such as the classroom or living room where they are resting. Generally, individuals exposed to 5000K - 6500K cool light are considerably more productive, while those exposed to 3000K warm light get into relaxed mode substantially faster. Smart LED Control System has greater flexibility, allowing users to control the fixtures from connected devices. Furthermore, users can adjust the colour temperature and the amount of intensity from the device to their preference. This project will use a colour mixing technique and dimming control to generate different colour temperatures and light intensity. This project will design a circuit that will be able to vary the light intensity and colour temperature of the LEDs from 3000K warm light to 5700K cool light with the extension of a phone application.
