Indoor lighting design should be analyzed for daylighting

However, not all lighting is in line with the scene atmosphere that the designer wants to create. Therefore, considering these factors in the early stage of building construction will bring considerable benefits to architectural lighting and create good quality light. surroundings.

Let's first take a look at the natural lighting reference value:

A few notes:

(1) The lighting windows should have sufficient lighting area to allow natural light to shine into the room. The ratio of the net area of ​​the window (the area after the edge of the window is removed) to the floor area is called the daylighting factor. In the rough working place, the lighting coefficient is more than one tenth, and the fine working place is more than one fifth.

(2) When the side window is used for lighting, the depth that the light can reach is enough to make the light shine to the working place, so the lighting is good and the depth coefficient is light. The depth factor is the ratio of the distance from the window to the opposite wall to the window height, and the window height is the distance from the upper edge of the window to the ground. If the upper edge of the window is more than 3.5m from the ground, the height of the window is the distance between the upper edge of the window and the working surface. When the side is lighting, the fine working place, the depth coefficient is ≤ 2, and the roughness is <4. The above-mentioned coefficient of double-side lighting can be improved. Doubled.

(3) In addition to the above-mentioned factors of the structural form of the house, the actual indoor illuminance is related to the presence of trees or trees outside the window, and is related to the indoor reflection coefficient.

The lighting design is not limited to the above data, and the above data is more for functional lighting. But lighting design is not limited to functionality, it also needs to take into account our visual beauty and display lighting art.

Different buildings have different functions and artistic expressions. We cannot rely on the above data to locate the advantages and disadvantages of their building lighting. Light and architectural space, the two have a mutual dependence and complement each other.

First of all, when there is light in the building space, it is possible to exert visual effects and identify the existence of people and objects in the space. At the same time, light also displays its state, change and expressive power on the basis of space, thus creating the art of light environment. By virtue of the characteristics of reflection, refraction and transmission, light creates a change in the brightness of light in the building space.

For our professional lighting designers, if we are involved in the application and influence of light in architecture in the early stage of construction, perhaps we can influence what kind of light environment we want and what kind of lighting effect we want. The lighting design, so that the building brings us not only the display of its architectural technology and art, but also presents the user with a high-quality light environment.

Figure: It can be seen from the daylight analysis that the lighting design of the indoor lighting exhibition is not very good.

Figure: The effect of the architectural lighting design is impressive.

Figure: A reasonable lighting design enriches the interior light.

The ideal is full, but the reality is very skinny.

Most of the time, we are involved in the lighting design only when the architectural drawings have been determined, and the lighting design can only be based on the existing lighting conditions. At this point, daylight analysis is very necessary!

If we can't get involved in architectural lighting design, at least our indoor lighting design should take into account the existing lighting conditions of the building, and then design the lighting after daylight analysis. Although this is a passive acceptance of architectural lighting, at least we can use technology to improve the space light environment.

For the domestic, lighting design is still an emerging profession, and has not received enough recognition and attention. This depends on the efforts of our lighting industry. I believe that the future lighting design is not just a career that can give many people work and income, but a career that can bring you a beautiful light environment.
