What is the hotel lighting design standard?

To answer this question, we must first have a general understanding of the types of hotels or hotels. For example, hotels and guesthouses are usually divided into business type and tourism type. Business hotels are usually located in economically developed cities, which receive business travelers and highlight functions such as office work, meetings and business banquets. However, tourist resorts are usually located in tourist attractions, highlighting the functions of vacation and leisure.

On the other hand, this distinction is relative, and their functions often cross each other; In addition, from the architectural features, all kinds of spaces divided by functions inside and outside the hotel are basically the same. Next, let's get down to business.

First of all, about the color temperature of the light source.

1. Warm white light source with color temperature around 3000K should be widely used. The reason is that no matter what type of hotel, it should be their common aspiration to create a cordial, warm and friendly atmosphere, and the lighting environment provided by the light source with a color temperature of 3000K can strengthen this feature of the wine spot.

2. Based on the study of human visual perception of color temperature and space, the hue of orange tends to be blue-purple, and orange makes people feel warm and close to us in the contrast at the same time; By memory, compare the above colors continuously and the result is the same.

3. This perception is closely related to some psychological evaluations and emotional activities such as kindness, warmth and friendliness.

4. Based on engineering practice, whenever a hotel lighting project can thoroughly implement this principle without interference from all sides, its effect is very good.

Second, split the light colors of different types of light sources.

1. Incandescent lamps and compact fluorescent lamps are just examples. An incandescent lamp with a label of 2800K and a compact fluorescent lamp with a label of 2850K (or 2700K) only show that their color tables are basically the same, but there are still subtle differences in the evaluation of light color (there are still differences between color tables and light colors): due to different spectral components, the light emitted by incandescent lamps is very similar to cobalt yellow or cadmium yellow of watercolor pigments, and the light emitted by compact fluorescent lamps is "loud" but "transparent".

2. Therefore, the lighting design should choose the light source category in a targeted way. In the case of the same color temperature, we should comprehensively weigh whether they are energy-saving in luminous flux and average life, easy to maintain and choose between light and color. Don't use incandescent lamps just because of "green lighting".

3. For high-class hotels, energy saving and easy maintenance are of course very important. For example, at present, the average life of good compact fluorescent lamps can reach 10000 hours (while incandescent lamps are only one tenth of it). Although the hotel avoided the cost of replacing light bulbs, it sacrificed "pure light color".

4. As for the problem of saving energy and prolonging the life of light bulbs, as far as the current situation in China is concerned, a large part of it can be solved by adjusting the light in time according to the requirements of natural lighting and guest activities, just like the headquarters building of China Bank. Of course, there are many ways to save energy, so this article will not be expanded.

Third, make rational use of the relationship between color temperature and illumination.

Make use of the matching relationship between illumination and color temperature to create a suitable space atmosphere in details. Generally speaking, color temperature and illumination should be matched in direct proportion, that is, high illumination, high color temperature and vice versa. The habit of domestic hotel lighting design is often high color temperature, but the illuminance is generally low, often falling into a "gloomy" atmosphere. This should be paid enough attention to in future design practice.

Fourth, direct lighting can be used instead of indirect lighting.

At present, the light trough has been widely used in various commercial space lighting, even submerged. With the development of electric light source and lighting technology, direct lighting can avoid the harm of uncomfortable glare to vision. Therefore, unless it is necessary for decoration, do not use various types of light-emitting troughs with serious luminous flux and inconvenient maintenance.

Fifth, realize the tone of unification.

Use light sources with the same color temperature to avoid light color disorder. Use light sources with the same color temperature to make the color of the light environment uniform. As far as the lighting design of the hotel is concerned, the unified tone conforms to the characteristics of the hotel because it does not emphasize conflict and drama. We have noticed that some domestic interior design companies that have done well still have many problems in this respect.

Choose a light source with high luminous flux utilization.

1, choose an illuminator with optimized parameters and high luminous flux utilization. We often encounter such a situation. Initially, the nominal total luminous flux of the light source is very high. However, due to the selection of lamps with low luminous flux output efficiency, the illuminance value calculated theoretically is far from the result measured by the illuminance meter after the actual completion.

2. It is suggested that when there is any doubt about the lamp efficiency parameters and light distribution curve parameters provided by the lamp manufacturer, the unit with relevant testing equipment should be entrusted for testing.

Seven, choose the appropriate light distribution, and judge the light distribution parameters such as light intensity distribution, central light intensity and half light intensity of the light distribution curve according to the room air ratio in different functional areas of the wine point, so as to avoid the loss of luminous flux in both aspects.

1. For example, the lobby of a bar is usually located in the podium of a building, and the ceiling is usually very high. It is very common to pick a height of more than 6 m, so it is necessary to choose an illuminator with narrow beam angle and long projection distance to prevent the upper part from being bright, while the ground and the human activity area at 1m from the ground are not bright enough;

2. On the contrary, if such light distribution is used in areas with low ceilings such as guest rooms, there will be problems such as bright ground and insufficient vertical illumination. The following two pictures are the light distribution comparison of PAR38/80W/ toe angle 120 and PAR56/300W/ toe angle 400.

Eight, the more advanced the hotel, the higher the color rendering index of the light source.

1, the color rendering of light source is generally evaluated by CIE's color rendering index, which is to evaluate the color rendering difference between the light source to be evaluated and the standard light source (all cloudy light) for several color samples including human skin color. Generally speaking, the higher the ra of a light source, the better its color rendering.

2. However, it should be pointed out that because Ra takes the average value of color samples, although some light sources have high color rendering index, they may not be able to display specific colors well. This should attract the attention of hotel lighting design.

3. In domestic lighting standards and design practice, color rendering has been neglected, and it is usually emphasized that light sources with high color rendering index are needed where color discrimination is required. In fact, in places where people have more contact, especially hotels, it is very important for guests to show a healthy complexion.

4. In addition, the light source with good color rendering can have lower illumination than the light source with poor color rendering under the same conditions. This is not to say that color development can replace part of the light, but that people should feel more clearly. The key problems of hotel lighting go far beyond the above. This paper only discusses the outstanding problems in the current lighting design practice from the author's point of view, for the lighting design colleagues to think and discuss.

To sum up: What standards should the hotel lighting design refer to? There is no answer to this question. Every lighting designer has his own style and characteristics, and every hotel also has its own style and application requirements. The above are for reference only!
