“God said there would be light, and there was light.” The role of light, whether natural light or indoor lighting, is extremely important to people’s lives. In modern interior decoration design, light is not only the condition of indoor lighting, but also the basic element to express the form of space and create an environmental atmosphere.

Without proper lighting, no matter how elegant the interior decoration is, it will only be a waste of space, and “there is no space without light”.

So what should be paid attention to in interior lighting design?

Modern architectural decoration not only pays attention to the components of indoor space, but also pays more attention to the aesthetic effects of lighting on indoor and outdoor environments and the psychological effects arising therefrom. Therefore, lighting is not only to continue natural light, but to make full use of the combination of light and dark in architectural decoration, and the combination of light and shadow creates a comfortable and beautiful lighting environment.

Therefore, people pay more and more attention to the lighting choice of interior decoration.

In the decoration, according to the illuminance required in different building indoor space environments, the lighting method and lamp type should be correctly selected to provide people with good lighting conditions, so that people can get the best visual effects in the building indoor space environment, and at the same time, they can obtain a certain atmosphere and artistic conception to enhance their architectural indoor space performance effect and aesthetic feeling.

There are four requirements for interior lighting design:


It means that the setting and selection of lines, switches, lamps and power distribution require reliable safety measures;


Functionality means that the use of functions in different types of buildings is not the same, and it needs to choose different lamps and illuminance according to the physiological needs of users. For example, the illuminance when we read a book and rest is different.

This has domestic to international illuminance standards recommended for each application site and activity form according to the visual health surface, brightness distribution values of each workplace, various glare evaluation levels, research data with strobe effects, etc., for us to query.


Artistry means that the use of a variety of different lighting techniques and colors will produce a variety of different psychological effects. The display of various shapes and three-dimensional, deep and different architectural styles require different effects through lighting design.


Economy refers to the use of advanced technology, give full play to the actual effect of lighting facilities, obtain greater lighting effects with as little investment as possible, and ensure the overall economy of lighting products throughout the life cycle.

How to choose the right lamp ten precautions

According to the above four disciplines, the author lists ten precautions, briefly describes how to choose the right lamp skills, for the reference of friends.

These ten tips can solve the problem of general indoor lighting in the decoration to meet all the needs of the user and provide an effective working environment:

1 Human vision is very dependent on the brightness of the surrounding horizon.

When the brightness of the environment increases, human motivation and overall vision also increase relatively, and the likelihood of errors decreases.

2 Soft lighting distributed in different surfaces of the room can give the space a sense of comfort.

Conversely, inappropriate or too much light will cause vision impairment and fatigue.

3 Proper reflection control protects vision.

Although reflections do not cause vision, they may cause irritation and damage to vision.

4 Good brightness contrast allows eyes to distinguish between objects and backgrounds.

Within a lighting system, good brightness contrast will not cause strong reflection glare, and provide people with a comfortable visual environment.

5 The direction and position of the luminaire projection is very important.

At the same time, it also affects the distribution of light and shadow.

6 The Shadow River enhances visual dimensionality and provides guidance.

Effective combination of scattered light and direct light produces good shadow conditions.

7 Selection of suitable color temperature – During the day, the color temperature of natural light sources changes.

Therefore, artificial light sources can select and adjust different color temperatures to create different lighting functions and situations.

8 Good color rendering index.

Color rendering index is a measure of the color reproduction ability of artificial light sources to express the natural color of an object. For interiors with a sense of design and rich furnishings, the color rendering ability of the light source is particularly important.

9 Light can affect people’s mood and feelings.

The feeling of the interior and the lighting is a subjective and unconscious impression. In recent years, the public has paid more and more attention to the importance of workplace lighting for productivity, mood and well-being.

10 The basic requirement of modern lamps and lighting design is energy saving and environmental protection.

Energy saving, environmental protection and health are the basic tenets of green lighting. In 1991, the green lighting advocated by the US Environmental Protection Agency has been popularized around the world, deeply rooted in the hearts of the people, and has a profound impact on lighting design. There are many solutions for the installation of luminaires and the re-engineering and refurbishment of old and inefficient systems.
