Abstract

Nowadays, many lighting application require complicated wiring such as home lighting appliances. From main power to the specific lighting equipment, the amount of wire for installation is large and messy. In order to solve the wiring problem, solar powered garden light is introduced. This study cover on step by step in order to design a solar powered garden light with motion sensor. Motion sensor is included in the solar garden light as it function available in market is monotonous. The calculation about specification, selection of components, assembly and performance assessment of solar garden light included in this thesis. The design process began with the amount of light lumen require in order to illuminate a predetermined area of a garden. The next step covered on the wattage and the types of lighting element and sensor that fit the criteria. Choosing the right battery and solar panel were the next steps. Schematic circuit design is done after choosing of components. The physical body of solar garden light is designed as well as the materials selection. Final step focus on the performance assessment of solar garden light. Parameter such as sensing distance and field of vision of the sensor, luminance of the LED and operating hours of solar garden light are tested. A prototype of circuit of motion sensor solar garden light was done at the end of the project with sensing distance of 4 meter , 30º dispersion angle, 100 lumen brightness, and minimum of six hours of operating hours. Physical body is designed with the suitable materials but the fabrication of physical body is not included in this study.
