Abstract
Solid-state lighting is a field that has developed rapidly over the recent years. Visible Light Emitting Diode (LED) has achieved higher luminous efficacy than that of incandescent light, subsequently incorporated into many lighting systems in household or in workplaces. Energy saving can be achieved by utilizing adaptive lighting systems which can adapt to ambient lighting. We discuss the ability of LED as an ambient light detector and subsequently propose a solution that would enable the LED to be used to illuminate and detect ambient light simultaneously. The proposed solution simplifies the circuit for illumination and light detection that could potentially reduce hardware cost for detection. This can potentially be used in automated light intensity control based on ambient brightness. � 2017 IEEE.
