ABSTRACT
The pollution of the environment and demand for energy are more and more serious because of the speedy development in scientific technology. The new scientific technology of economizing energy and environmental protection is everyone's striving goal. Solid-state lighting source, such as MOCVD LED, is a light source component which accords with this goal.
This paper presents an analogue photovoltaic warning lighting system. The proposed system consists of a photo voltaic module, phase control circuit, LED driving circuit, and a battery. In the paper, the types of photo voltaic module are introduced first. Then, implement a phase control circuit, an analogue controller and a switch circuit. In the sunny daytime, battery is charged by phase control circuit and during night supply to a LED lamp to achieve the capability of automatic warning lighting. Finally, an analogue controlled photovoltaic lighting system is implemented and to verify the theoretical analysis.
Keywords: Photo-voltage energy, light emitting diode, warning lighting, MOCVD LED
