Artificial light is made up of advanced technology that resembles natural light (sunlight). For example: bulbs, tube lights. Artificial light is developed at the end of 19th and beginning of the 20th century. There are two ways to measure natural light i.e. the specific frequency range and the strength of illumination that measure in lumens. Artificial Lights can easily be seen around you. Peoples usually use artificial light at a wide scale in their homes, at commercial places and many other places. These are available at large variety like in shapes, sizes, colours and even in level of brightness.
An incandescent light source is the most common type of source in which sun, light bulbs and fires can be included. Incandescent light is a type of light source which includes the vibration in the entire atom, as when the atoms are heated then the thermal vibrations in the form of electromagnetic radiations are released. Depending on the temperature the materials vary in emitting energy, at low temperature of the materials, the emittion of radiation takes place through infrared wavelength in the photons. A common example of incandescent light source is when a metal is heated, the atoms present in the metals gets vibrated and emit photons which emit radiations to make it visible to the human eye by raising the wavelength in the spectrum.
As compared to incandescent light sources, these types of sources involve only electrons instead of the whole material vibrations, which takes place in normal or lower temperatures making it different from the Incandescent type of sources. Basically, we can say that when the electrons emit some part of its energy in the form of electromagnetic radiations then the type of light is known as luminescence light. When an electron drops down in temperature then the specific light color is produced through the energy level decrement. Some common examples of Luminescence light source are neon lights, fluorescent light, bioluminescence, fluorescence light, etc. Fluorescence light is the most common example of luminescence light source which can be further divided into two parts which are electro-luminescence and photo-luminescence which can include computers screens and televisions. Bioluminescence is also the most common example of luminescence which even includes animals like fireflies.
The most important difference between natural light and artificial light is that natural light can be found in nature but artificial light are electronic which is formed with the help of advanced technology. Natural light has no control over the usage as it is based on the duration of time but this is not in the case of artificial light. Usage of artificial light is limited. The amount of light produced is the main factor of using artificial light. If the artificial light is produced in less quantity then the consumption is also low.
