1. A system of energy saving lighting, comprising:
- a sensor component which comprises a motion sensor having a detecting area and a light sensor for measuring light intensity in said detecting area;
a power supply component, which comprises a solar power supply element which converts solar power to electrical energy, and a rechargeable battery element being charged by said solar power supply element to form a power source;
a light component which is electrically connected to said power supply component to generate light; and
a microcontroller which not only controls charging and discharging of said rechargeable battery element but also controls said light component in responsive to said sensor component, wherein when said motion sensor detects a motion within said detecting area, said light sensor is activated for measuring the light intensity in said detecting area, at the same time, said microcontroller determines a brightness of said light being required within said detecting area in responsive to the light intensity being measured by said light sensor, such that said light component is controlled to initially generate enough said light within said detecting area, wherein when there is not motion within said detecting area, said light component is switched off by said microcontroller.
