This research aims at achieving several objectives that might help us economize electricity through these mains points. First of all, utilization of the external enlightment for enlightening inside, developing the lights of cars and streets, saving the electric power and reducing costs.
Personally, I see that electricity is a very significant source of power and energy and power nowadays, thus, I was determined to invent and make something new that could contribute to save this valuable source of energy. I took my turn as part of my awareness of this project, and as a diligent I worked hard to collect information about electricity and different tools. The idea of my project can be summarized in the principle of working for my project which is as this: the principle of working of this circuit starts when the sensor receives the light coming into a place, the much the amount of light entering the higher the current of the sensor be. As a result, the current of the circuit will be lesser, thus the lightning of the lamp will be also lesser and visa versa, the lesser the amount of light entering, the higher the current of the circuit, thus the light of the lamp will be stronger. For more explanation, a place that needs a lighting of 100 watts in order to be fully lighted. If the amount of light coming which is about 50 watts of external light, thus the lamp will produce lighting of about 50 watts, so the amount of light coming changes into 70 watts, so the lamp might produce lighting of about 30 watts, and so on throughout day, the larger the light entering the lesser of the lamp lighting will be. all this depends on the amount of light that the sensor receives.
My project needed some tools like, a source of electric exertion, a lamp, a transistors, dilators, fuse, commutator, and diodes.
The outcomes of my project are that we could control the lighting of the lamp by using the external lighting through the internal lighting. So this could save energy and reduce costs.
