Getting the best possible light
 
Lighting design can be said to be optimum when it has taken account of the nature of the space, its purpose, the special features of the building and the intentions of the architect, and has treated light as an additional material and design element. Artificial lighting can be superior to natural lighting. It can help people find their way around the interior of a building. Light becomes the fourth dimension in architecture.
 
 
Space and function
 
The space to be lit is divided into functions and areas for the purpose of defining the lighting tasks. These areas may be workplaces, sales areas, counters and shelving, entrances and walkways. We talk about "zoning". The zones are defined according to the tasks to be performed in them, their functionality and their emotional impact.
 
 
Light shapes the space
 
Based on experience and intuition, lighting designers decide which lighting effects will best serve the intended purpose. In the various zones, light is used for background lighting, for accent lighting or for marking routes, for helping people find their way around and for highlighting architectural features. Light shapes the space and helps people perceive their surroundings. There is a virtually unlimited number of ways in which style elements, lights and lamps can be combined. Often it is a good idea to call in a competent partner.
 
 
Light and lamps
 
Depending on the task that the lighting has to perform, one or more different types of lamp may be needed. With the aid of initial estimates and computer programs, it is possible to define the number of light sources required, their wattage and other technical details. This goes hand in hand with selecting the luminaires.

세부조정
 
흔히 조명설계자는 여러 가지 상충되는 요구조건을 조정해야 합니다. 전반적인 설계, 등기구 기술, 경제성, 에너지 절약 및 다른 장치와의 상호작용 등을 고려해야 합니다.
 
 
 
조명시스템의 품질특성:
 
품질특성에 대한 설명은 아래와 같습니다.
 
· 조도
· 휘도 분포(Luminance Distribution)
· 눈부심 감소 및 직사광
· 직사광 및 그림자의 영향
· 광색 및 연색성(Color Rendering)
· 쾌적성

조도
 
조도는 작업의 성과, 생산성 및 안전에 지대한 영향을 줍니다. 그러나 조도를 높이면 따라서 비용도 증가하게 됩니다. 따라서 조도 권장값은 일반적으로 가시성, 쾌적성, 비용 및 에너지 소비를 고려하여 절충하도록 합니다. 

Luminance distribution
 
For optimum vision, the German DIN 5035 standard recommends a luminance ratio of 3:1 between the close field and the ambient field. The close field is the work area and ambient field is the immediate environment of the work area. This ensures that the eye adapts properly
 
 Reducing glare
 
When choosing and positioning lamps and luminaires the danger of glare must be taken into account. Thus an unfavorable positioning can lead to direct glare (looking directly into the lamp) or to reflected glare (across shiny or reflecting surfaces). This can impair the vision. In order to minimize reflected glare surfaces of workplaces should be mat. Furthermore the medium light density at the room boundaries should not be more than 200 cd/m² sein.

Directed light and the effects of shadow
 
For right handed people the light should fall onto the work surface from the left side. Otherwise shadows could impair perception. Strong contrasts should be avoided.

Light colors and colors rendering
 
Only use lamps with good to very good colors rendering (like Lumilux fluorescent lamps or halogen lamps) in order to naturally represent furnishings and other materials.

쾌적감
 
크루이토프 곡선(Kruithof comfort curve)은 어떤 색온도에서 어느 정도의 조도를 적용했을 때 가장 쾌적감을 느끼게 되는 지 보여 드립니다.

2700-3000° K의 낮은 색온도의 조명시스템은 50-100 lux 범위에서 쾌적한 느낌을 주는 반면 동일 색온도에서 조도가 높아지면 쾌적감이 감소할 수 있음을 보여 주고 있습니다. 예를 들면 실내에 있는 사람에게 쾌적한 느낌을 갖는 조도는 색온도6000° K 시 최소 500 lux 이상입니다.
