Modern office space is no longer just a place for employees to complete their work independently, but more of a communication center, a place for communication and exchange of information between employees, employees and customers, and their mutual communication and exchanges are essential for completing the work. Play an increasingly important role.

We are busy operating computers in the office, writing documents, reading materials, making phone calls, meetings, discussing work with colleagues, etc. All these activities have their own visual requirements, and it is necessary to carry out corresponding lighting design.

The bright and comfortable office light environment can protect people's health, interest and enthusiasm; reduce fatigue and improve work efficiency.

We all know that natural light is the most comfortable way of lighting, but the main structure of most modern office buildings is made up of layered floors, which will block the natural projection of sunlight into the room.

Therefore, artificially create a light-dark contrast that is distributed too much and too heavily, which is much more serious than what is seen under natural conditions. Although daylight is real and natural, the way daylight enters the room is limited, which creates an uncomfortable and unnatural environment. Therefore, artificial lighting is needed to supplement it to achieve a comfortable environment.

7 issues that need to be paid attention to in hotel lighting design

Hotels and hotels are usually divided into business type and tourist resort type. Business hotels are usually located in economically developed cities and receive business travelers, highlighting functions such as office, conference, business banquets, etc.; tourist resort hotels are usually set up Among tourist attractions, vacation and leisure functions are prominent. But this distinction is relative, and their functions are often intersecting.

In addition, from the perspective of architectural characteristics, the various spaces divided by functions inside and outside the hotel are also roughly the same. For example, compared to the Le Méridien Hotel in Hong Kong Cyberport and the Garden Hotel in Guangzhou, although the characteristics are very different, they all have a reception lobby, that is, a Portman-type space, and they have various types of guest rooms, Chinese and Western restaurants, and many more. Function hall.

Therefore, from the perspective of hotel lighting design, their commonalities are basically the same. In the design process, the following 8 important issues need to be paid attention to:

1. It is necessary to generally use warm white light sources with a color temperature of about 3000K

The basis is: no matter what type of hotel, it should be their common desire to create a cordial, warm and friendly atmosphere, and the lighting environment provided by the 3000K color temperature light source can strengthen this characteristic of the hotel.

(1) Based on the research of human vision on the temperature perception and spatial perception of colors, the hue is biased towards orange and yellow and the same hue is biased towards blue and purple. When contrasted at the same time, orange and yellow make people feel warm and close to us; based on memory , When the above colors are continuously compared, the result is the same.

(2) This perception is closely related to psychological evaluations and emotional activities such as kindness, warmth, and friendliness in the depth of psychological arousal.

(3) Based on engineering practice, whenever a hotel lighting project can fully implement this principle without interference from all aspects, the effect is very good.

2. Under the condition that the color temperature of the light source is the same, the light color of different types of light sources should be analyzed in detail

(1) Take only incandescent lamps and compact fluorescent lamps as examples. An incandescent lamp with a nominal name of 2800K and a compact fluorescent lamp with a nominal name of 2850K (or 2700K). This just indicates that their color tables are roughly the same, but the light color (color table and light color are still the same). There are still subtle differences in color perception: due to their different spectral composition, the light emitted by incandescent lamps is very similar to the cobalt yellow or cadmium yellow of watercolor paints, and the hue is "loud" and "transparent"; The light emitted by the fluorescent lamp looks like earthy yellow, and the color tone is a little muddy.

(2) Therefore, lighting design should select the type of light source in a targeted manner. Under the same color temperature, it is necessary to comprehensively weigh whether they are energy-saving in terms of luminous flux and average life, whether they are easy to maintain and the light color.

(3) As for the issues of energy saving and prolonging the life of light bulbs, as far as the current domestic situation is concerned, a large part of it can be adjusted in a timely manner through the intelligent control system, like the Bank of China headquarters building, in combination with natural lighting and the brightness requirements of guest activities. Light, come and solve it.

Of course, there are many ways to save energy, but they are beyond the scope of this article.

3. Pay special attention to the relationship between color temperature and illuminance

Use the matching relationship between illuminance and color temperature to carefully create a suitable space atmosphere. Generally speaking, color temperature and illuminance should be in direct proportion, that is, high illuminance, high color temperature, and vice versa. The custom of domestic hotel lighting design is often that the color temperature is very high, but the illuminance is generally low, often falling into the "gloomy" atmosphere as shown in the figure below.

This should be given sufficient attention in future design practices.

4. Use light sources with the same color temperature to avoid chaotic light colors

The same functional area, surface and object use light sources with the same color temperature to make the color tone of the light environment uniform. As far as the lighting design of the hotel is concerned, because the emphasis is not on conflict and drama, a unified color tone is in line with the characteristics of the hotel. We have noticed that some domestic interior design companies do well, and there are still many problems at this point. For example, the Changlong Hotel project designed by Guangzhou Jimei Group is very good in other aspects, but there are still some problems with the lighting: some rooms use cool white light sources; some rooms have both warm white light sources and cool white light sources , Makes people feel very uncomfortable.
