Applications of Laws of Illumination
- Laws of illumination is used in astronomy, to calculate the brightness of the star.
- Used in design, engineering and architecture.
- Inverse square law is used in photography to find the variation in illumination on an area as it is moving closer or away from the Light source.
- Illumination laws are used in medical Imaging.
- Used in navigation and aviation for safe landing, take -off and in low brightness situations.
Laws of Illumination
Light is an essential element in human life and the day-to-day activities of human beings eventually depend on the light. Where there is no natural light, the use of artificial light is required. Artificial lighting is generated electrically, because of its cleanliness, ease of control, accuracy, and stable output, as well as its low cost it is taking an increasingly major part in modern everyday life.
The science of illumination engineering has become of major importance. Light is a form of luminous energy. Several forms of incandescent bodies are the reference of light and the light radiated by such bodies depends upon the temperature of bodies. Heat energy is emitted into the medium by a body that is much warmer than the medium surrounding it. The heat of the body can be categorized as red-hot or white-hot.
