Master's thesis

Abstract:

An efficient and intelligent Light Emitting Diode (LED) lighting is proposed for an optimal implementation of an enhanced dimming and switching ON and OFF the light source. The controlled is made using both the switch button control terminal and the Bluetooth wire- less remote control interface. The proposed design supports both the switch button control and the wireless dimming control of the pulse width modulation (PWM) pulse signal from the microcontroller unit (MCU) to the respective light sources. An illumination Light Depen- dent Resistor (LDR) is used for sensing and transmitting the sense illuminance flux values to the MCU. The MCU will desired the correct value of the PWM duty cycle signal to be propagated to the LED light sources. The mixture of the RGB color primary vectors is considered for ensuring that the international commission on illumination (CIE) 1931 chromaticity coordinates is synthesized. The verification of the proposed designed parameters and its functionalities in comparison with the existing commercial LED light solutions is highlighted in this thesis work. Most of the proposed designed parameters work comparable to the current commercial LED lighting solutions. The reason been is that the generation of the spectrum coloration of the RGB light has much flexible user controlled interface. The design sys- tem experiments on intelligent and enhanced controlled of an LED lighting have shown negligible time delay of its task execution.
