The publication is based on the book Lighting Design, the original author William F. (Bill) Blitzer is an outstanding lighting designer and former chairman of Lightolier, an important American company founded by his grandfather in 1904. Lighting company. After leading the lighting industry for a lifetime, Bill founded Asia Pacific Lightshop in 2003, sponsoring and supporting the development of Lighting Design. The North American Institute of Lighting Engineering (IES) is grateful to Bill and Lightshop for their generous donations of related materials in this consumer publication.
Light - creative medium
Light is a creative medium... the most powerful of all media. Most of what we know about our own world is perceived through our eyes, and what we have learned is that the way we look at things depends on how they are illuminated.
Lighting design - show life
This application note shows how lighting can make a difference – it's a practical and creative guide to designing lighting. It focuses on three basic choices:
1. What to light?
2, how to take (How to lightit)
3. What to lightit with
We will focus on each of these three decisions and the factors that affect them.
"what to light" and "how to lightit" to address lighting needs and methods in typical lighting applications such as dining areas, bedrooms, living rooms, and the like.
"what to light with" means the appropriate source of light, based on the criteria and conditions set by the "what to light" and "how to lightit" decisions. Lighting and control modes.
What to light
“What to take†is usually determined by the use of the space. The properties and characteristics of the object and surface are important, such as the living room, bedroom and dining area. Often, determining how a space should be designed for lighting can be considered in three ways.
These aspects are:
Task lighting
Accent lighting
Ambient lighting or "space" lighting (Ambientor "space" lighting)
What we mean by "seeing" does not mean the light itself, but the picture that the light perceives after being reflected by the surface of the object. Therefore, we need to consider the characteristics of the surface being illuminated.
Is it bright or dark? Dark surfaces absorb more light and reflect less light;
Is it polished or mirrored? Polishing the polished surface will reflect the image;
Is its texture fine or rough? A textured surface scatters the light striking it;
Do we want to highlight or weaken its color? The color of the surface of the object is determined by the color rendering ability of the light source.
As the first step in lighting design work, the space should be analyzed based on the following aspects.
Function: What kind of activities do people perform in this space?
Visual Assignment: What do you most want people to see?
Objects: What do you most want people to see?
Architectural features: What is worth highlighting?
Furniture location: Where do people sit? Or where are you standing?
Emotion: What kind of atmosphere do people want? Need to change?
Style: Is there something that lighting should work with?
Step 2: Try setting the priority.
What is the most important? Try to find a visual focus on the space you want it to catch the eye. In the dining room or living room, it is most likely a table and its furnishings, a painting, or a vase decoration and a fireplace.
Of course, in a space, there may be multiple lighting targets that need to be prioritized, such as a "work" area such as a sideboard, table, or kitchen counter.
These prioritized goals should consider operational lighting or accent lighting, as will be described later.
Then, consider the space as a whole.
Illuminating the wall can make the space look wider;
The soft light hidden around the furniture creates an intimate atmosphere;
The “sparkling and sparkling crystal†lighting effect from the cut crystal or polished metal will convey the festive atmosphere;
Indirect lighting focuses on the lighting of smallpox to make the space more formal and open;
Focusing on a small piece of carpet on the floor with a downlight can make the space look warmer and more comfortable; but when the downlight is directly projected onto a smooth surface such as a glass table or marble floor, it is likely to cause discomfort. Reflecting glare.
We'll talk more about these aspects of designing with lights later.
How to take photos (Howtolightit)
Once we've analyzed the space and decided what "what tolight", we can use three basic lighting techniques and methods to determine how to best design the lighting.
Ambient lighting - basic, holistic lighting that can:
Make people move easily and safely
Defining space
Make the space look bigger
Make the space more comfortable by balancing the brightness of the surface in the field of view
The general illumination of the objects and surfaces that illuminate the lower part of the room creates a warm and intimate feel, while the indirect lighting that illuminates the upper walls and ceilings makes the space look more rational, quiet and spacious.
Traffic Lights are traffic lights that command traffic and are generally made up of red lights,green lights and yellow lights.The red light means no traffic,the green light is allowed to pass,and the yellow light is a warning.
Traffic lights are divided into:light motor vehicles, no-motor vehicles lights,pedestrian signal lights,direction indicator lamp(arrow lights),driveway lights,flashing warning lights,road and rail light plane crossing.
