Disadvantages of Laws of Illumination
- Proper maintenance is required to get better performance.
- Lighting perceptions are personal and will be different from one another that will effect the consideration of lighting environments.
- Fixing with the laws of illumination can increase the cost.
- Some laws of illumination can be complex.
- Using illumination laws provides energy efficiency and some lighting solutions can cause light pollution.
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.
