If you want to answer this question, we must first have a general understanding of the types of hotels or hotels. For example, hotels and hotels are usually divided into business-oriented and tourism-oriented hotels. Business-oriented hotels are usually located in economically developed metropolises, which receive business travelers and highlight functions such as office work, meetings and business banquets. However, tourist resort hotels 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, the various types of spaces divided by functions inside and outside the hotel are also basically the same. Next, let's get down to business.

1. About the color temperature of light sources

1. Warm white light sources should be widely used, with a color temperature of about 3,111 K. The reason is that no matter what type of hotels, it should be their * * * pursuit to create a cordial, warm and friendly atmosphere, and the lighting environment provided by light sources with a color temperature of 3,111 K can strengthen this feature of wine spots.

2. Based on the study of human visual perception of temperature and space of color, it is found that the same hue of orange color is biased towards blue-purple color. When compared at the same time, orange color makes people feel warm and close to us. Based on memory, the results are the same when the above colors are continuously compared.

3. On the psychological level, 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 completely implement this principle without interference from all sides, its effect is very good.

2. Separate the light colors of different types of light sources

1. Take incandescent lamps and compact fluorescent lamps as examples. An incandescent lamp with a label of 2811K and a compact fluorescent lamp with a label of 2851K (or 2711K) only indicate that their color tables are basically the same, but there are still subtle differences in the evaluation of light color (color table and light color are still different): because of their different spectral composition, the light emitted by incandescent lamps is very similar to cobalt yellow or cadmium yellow of watercolor pigments, and the color tone is "loud" but "transparent" The light emitted by compact fluorescent lamps is very similar to khaki, and the color tone is a little cloudy.

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

3. For high-end hotels, energy saving and easy maintenance are of course important. For example, at present, the average life of a good compact fluorescent lamp can reach 11111 hours (compared with incandescent lamp, which is only one tenth of it). Although the hotel avoids the cost of replacing light bulbs, it sacrifices "pure light color".

4. As for the problems of saving energy and prolonging the life of light bulbs, as far as the current situation in China is concerned, a large part of them can be solved by combining the requirements of natural lighting and guest activities for brightness, and adjusting the light in time through intelligent control system, just like the headquarters building of China Bank. Of course, there are many energy-saving methods, which will not be expanded in this paper.

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

Make use of the matching relationship between illuminance and color temperature to create a suitable space atmosphere in detail. 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 that the color temperature is high, but the illumination is generally low, and it is often caught in a "gloomy" atmosphere. This should be paid enough attention to in future design practice.

4. If direct lighting can be used, indirect lighting is not used.

At present, light troughs have been widely used in all kinds of commercial space lighting, and even some of them are flooded. With the development of manufacturing technology of electric light sources and lighting lamps, the harm of uncomfortable glare to vision can be avoided by direct lighting. Therefore, unless it is required for decoration, various types of light-emitting troughs that are serious in light flux and inconvenient to maintain should not be used.

V. Uniform color tone

Use light sources with the same color temperature to avoid the disorder of light colors in the same functional area, surface and object, and 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, the unified tone is in line with the characteristics of the hotel. We have noticed that some domestic interior design companies that have done well still have many problems in this regard.

VI. Choose illuminators with high light flux utilization rate

1. Choose illuminators with optimized parameters and high light flux utilization rate. We often encounter such a situation. Originally, the nominal total luminous flux of the light source was very high. However, due to the selection of lamps with low luminous flux output efficiency, the calculated illuminance value in theory is far from the result measured by the illuminance meter after the actual completion.

2. It is suggested that when there is doubt about the efficiency parameters and light distribution curve parameters of the luminaire provided by the luminaire manufacturer, the unit with relevant testing equipment should be entrusted to carry out testing.

VII. Select the appropriate light distribution, and discriminate 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-to-air ratio of different functional areas of the wine spot, so as to avoid the loss of light flux in two aspects.

1. For example, the lobby of a wine shop 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 6m. It is necessary to choose an illuminator with a narrow beam angle and a long projection distance to prevent the upper part from being very 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, the ground will be very bright and the vertical illumination will be insufficient. The following two figures are the comparison of light distribution between PAR38/81W/ beam angle 121 and PAR56/311W/ beam angle 411.

VIII. The more advanced the hotel is, the higher the color rendering index of the light source will be.

1. The color rendering of the light source is generally evaluated by CIE's color rendering index, which is to evaluate the difference of color display between the light source to be evaluated and the standard light source (all-cloudy sky light). GeneRally speaking, the higher the ra of a light source, the better its color rendering.

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

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

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

To sum up: What standards should the lighting design of hotels 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, so the above is for reference only!
