What is lighting?
Lighting is the effect of light which could either be natural or artificial. While natural is predominant in the day artificial light demand is at peak at night. Example of artificial includes: electric lights, gas lighting, candles, and oil lamps.
Forms of lighting
Indoor Lighting
This form of lighting includes fluorescent lighting, neon lighting, LED, high intensity discharge.
Outdoor lighting
This form of light includes: street lights used to illuminate roadways and walkways at night, beacon lights positioned at roads' intersection to aid in navigation, security lights which may include floodlights used to deter crime and so on.
Reasons for controlling lighting system
Information given in this articles and others published on this website may not represent general view but personal opinion. So the reasons for controlling lighting system given here is my opinion.
Energy saving: Light intensity needed in your library or laboratory is not needed in your bed room. Employing a dimmer system for your bed room lighting will invariably reduced your energy consumption.
Still on energy saving, I will give a live scenario: I have a house in my country home, work in a city far away and I only go home once a while. Security lighting system is provided around the house to provide illumination at night. if no one is around to turn the light off, the light will remain on even in the day when it is not needed and consumes energy which I will have to pay for. That was the case in my dad's house before I introduced automatic lighting control system into it.
Usage: In some applications for instance stage lighting in theatre house, purpose of a controlled lighting is rather given more priority than energy usage.
