Hotel and the hotel is usually divided into business and tourist vacationing industry, business type hotel is located in the economically developed generally will, are business travel guest reception, office, conference, business banquets and other functions; Tourist vacationing industry hotels are usually located in tourist areas, outstanding is on vacation and leisure function. But this distinction is relative, the functions of them are often overlapping; In addition, from the point of architectural features, the hotel internal and external based on function partition of the space, also is same. Hong Kong cyberport Amy hotel, for example, compared with guangzhou garden hotel, although characteristics is not the same, but they all have reception lobby, namely portman type of space, there are various types of rooms, and Chinese restaurant and western restaurant and multi-function hall. So, from the perspective of hotel lighting design, their commonness is essentially the same.
1.1 to commonly used warm white light source, color temperature is about 3000 k
The idea was that: no matter what kind of hotel, build a cordial, warm and friendly atmosphere, should be their common pursuit, and the color temperature of 3000 k light source provided by the lighting environment, to strengthen wine this characteristic. (1) based on human visual perception of color temperature and the study of spatial perception, color should be orange color with hue be violet color, the contrast at the same time, orange, yellow, let a person feel warm, is close to us; Based on yi, continuous comparison in the colour, and the result is the same. (2) this kind of consciousness, on the psychological level of depth to raise, it is the same kind, warm, friendly such psychological evaluation and emotional activities closely together. (3) based on engineering practice, when a hotel lighting project, in the absence of all aspects of interference, thoroughly carry out this principle, the effect is very good.
1.2 under the condition of the light source color temperature scale say consistent, light color concrete analysis to the different categories
(1) only in incandescent and compact fluorescent lamps, for example. A nominal is 2800 k incandescent lamp and a nominal is 2850 k (2700 k) may also be of compact fluorescent lamps, this is indicative of their color table is generally consistent, but the light color (color table and light color is still differentiated) evaluation namely lubricious feeling there are subtle differences: because of their different spectral composition, incandescent light emitted from resembling watercolor cobalt cadmium yellow, yellow or tonal "vocal" and "transparent"; And compact fluorescent light is like yellow, tonal some turbidity. (2) so, lighting design is targeted to choose the light source, the color temperature under the same conditions, should with a weigh them on the luminous flux, average life expectancy is whether energy saving, easy to maintain and the trade-off between light color, don't cry because it is "green lighting" (I claim to "green lighting" to treat specific analysis), instead of using incandescent lamp. (3) for hotels, energy-saving and easy to maintain is important, for example, is a good of the average life span for the compact fluorescent lamps can reach 10000 hours (and incandescent lamps only one over ten of it), although the wine shop was relieved from the cost of replacement bulbs, but at the expense of his "pure light color". (4) as to the problem of energy conservation and to extend the lamp life, is the current domestic situation, a large part of the can like the bank of China headquarters, in combination with natural lighting and the guest activities on the brightness requirements, timely adjusting light through the intelligent control system, to be solved. Energy saving method, of course, there are many, but is beyond the scope of this article.
1.3 pay special attention to color temperature and the relationship between the intensity of illumination
Using the matching relation between intensity of illumination and color temperature, meticulous build suitable space atmosphere. Generally speaking, the collocation of color moderate intensity of illumination should be proportional, namely high illumination, high color temperature, and vice versa. Domestic hotel lighting design is often, colour temperature is very high, but the intensity of illumination is generally low, often in the atmosphere of the "dark" represented in the figure below. This design practice in the future, to give enough attention.
1.4 can use direct lighting, using indirect lighting
Light tank has now been widely used in all kinds of commercial space lighting, and even some flooding. With the development of electric light source, lighting lamps and lanterns manufacture technology, with direct lighting has been able to avoid the dangers of discomfort glare on the visual, so, unless the decorative requirements, otherwise, don't adopt optic waste and inconvenient maintenance of various types of light-emitting slots.
1.5 use the same color temperature of light source, avoid the light colour desultorily
The same function areas, surface and object, use the light source of color temperature is consistent, the light environment is tonal unity. In terms of lighting design of the hotel, because the stress is not the conflict and drama, so those who unite is tonal didn't accord with the characteristics of the hotel. We have noticed that some domestic do good interior design company, still there are many problems on this point. For example, long lung guangzhou jimei group design of the hotel project, other ways are good, is the lighting still have some questions: some rooms with cold white light source; Some rooms ranging from warm white light source, cold white light source, let a person feel very uncomfortable.
1.6 choose high luminous flux utilization illuminator
(1) selection of parameter optimized design, high utilization rate of luminous flux illuminator. We often encounter such a situation, original source of the nominal total luminous flux is high, but because of the luminous flux output efficiency &low lamps and lanterns, bears fruit in theory computing illuminance value and the actual finished, use luxmeter survey results. (2) advice in a care apparatus for efficiency parameters provided by the manufacturer of lamps and lanterns and light distribution curve parameters when in doubt, should entrust a relevant unit testing equipment, for testing.
1.7 select the appropriate light distribution
For wine point of different function areas than room empty, light intensity distribution of light distribution curve, the center light intensity and light intensity in the half light distribution parameters to identify, in order to avoid the two aspects of light loss. (1), for example, drinks the front office is usually located in skirt building construction, the ceiling is usually very high, high 6 m above is very common, choose narrow beam Angle, and cast light distance long illuminator, prevent the upper is very bright, and the ground and from the ground 1 m in terms of active area but brightness is not enough; (2) on the other hand, if the guest room ceiling shorter area such as use of such a light distribution, the ground will appear very bright, and vertical illumination is insufficient, etc. The following two figure is PAR38/80 w/beam Angle and PAR56/300 w / 120 beam Angle of 400 compared with light.
1.8 the more advanced hotel, light source color rendering index will be higher
(1) the light source color rendering generally with CIE color rendering index evaluation, it is including the person's skin color 10 several kind of color, light source used for evaluation and standard light source (the cloudy sky light) color shows the differences of appraisal. Generally speaking, the higher a light source of Ra, indicates that it is better color rendering. (2), but it should be pointed out that, for Ra is the average of the color sample, so, although some of the light source color rendering index is high, but for a particular color may be not good. This will cause the attention of hotel lighting design. (3) in the domestic lighting standards and design practice, has been the color are not very seriously, usually stressed in the places where requires color discrimination Only need light source of high color rendering index. But it is not, in general have more contact with people, especially in the hotel, guests can appear healthy color of skin is very important. (4) in addition, good color light than the color difference, under the same conditions, can have a low intensity of illumination. This is not to say can replace part of the color intensity of illumination, but people on the feeling to clear some. Hotel lamp act the role ofing
The key problem is far more than these of hotel lighting, this article only covers the author thinks, the glaring problems of lighting design practice, for lighting design colleagues thinking and discussion.
