Design is the science and the art of making something useful to humanity, and light design is simply the application of light to the environment. Such light can be natural or daylight. Light design depends on the mixture of certain scientific principles, established theories, and conventions, and few aesthetic, and human factors applied in an unusual fashion. Over the years the aspect of lighting has been faced with two powerful forces which are the energy efficiency and the quality of illumination. When the profession of lighting started, the quality of light was held up in high esteem. Also, the energy efficacy became a problem in the design of different building. Previously, attraction, well-lighted space were the concern of lighting designers. But it has taken a new dimension in this era; there has been a drastic improvement of lighting technology. There several consideration to take note in design verlichting.
The illumination level which depends on the light source spectrum
The lighting recommendation depends on the lumens and footcandles; it does not account for specific effects of the light source spectrum. There are some numbers of details to consider of the light source spectrum to give better reflection to the human vision or sight. But it has two distinct concerns
- The interior lighting at exerting indoor light levels
- The low levels of outside electric lighting at night
The light quality
Lighting used commonly have a different human reaction to the environment. These responses range from the awesomeness of the illuminated effects or the emotional feedback of candle light dinner to the deceptive impacts on employee productivity In offices and the sales made in retail stores.
A common trend in lighting research and philosophy is the single concept of lighting quality which plays a necessary role to the quantity of light. The quality of the light in an environment is increasingly elusive, despite the trials to make metrics ‘of lighting. The lighting quality still is a combination of the physical quantities.
There are three types of lighting quality
- Good lighting, when the lighting system is technically sound. It lifts the spirit of the viewers
- Bad lighting, when the lighting system is technically wrong and suffers from poor quality
- In-different lighting, this when the system is with no defects
This is the amount of light in a certain environment and its effects on the people present in that particular location.
