【 Weak current College 】 hotel room lighting engineering design case study

Summary: guest houses and hotels are usually divided into the business and tourist resort, the hotel is located in the economically developed, reception is business travel guests to prominent Office, Conference, business banquets, and other functions; tourist resort hotel is located in the scenic highlights of a holiday and leisure features.
1. a focus on issues of guesthouses and hotels are usually divided into the business and tourist resort, the hotel is located in the economically developed, reception is business travel guests to prominent Office, Conference, business banquets, and other functions; tourist resort hotel is located in the scenic highlights of a holiday and leisure features. But this distinction is relative, they often cross; in addition, the characteristics from the building, the hotel's internal and external classification based on the functions of various kinds of space, it is generally the same. For example, the Hong Kong Cyberport Meridien and Guangzhou Garden Hotel, although the features are not the same, but they all have a reception lobby, i.e. Portman type space, there are various types of rooms and Western restaurants and function rooms.　　Therefore, from the angle of the hospitality lighting design, their similarities are basically the same.　　1.1 to commonly used warm white light, the color temperature to 3000K based around: no matter what type of hotel cordial, warm atmosphere and a friendly atmosphere, it is their common demands and color temperature 3000K light provides illumination environment, to strengthen the point of this wine.　　(1) based on human visual perception of colour temperature and study on space perception, hue too orange colors with hue too blue purple color, in contrast, at the same time, Orange, yellow, feel the warmth from us near; based on memory, the color contrast for continuous, the result is the same.　　(2) this perception, mental level of depth of draw, it is the same kind, warm, friendly and some psychological evaluation and emotional activities closely linked.　　(3) based on the engineering practice, whenever a hotel lighting project, without the interference of the complete implementation of this principle, the effect is very good. 1.2 in light color temperature nominal consistent case, to different categories of light sources of light color specific analysis (1) only to incandescent lamps and compact fluorescent lamps, for example.　　A standard called 2800K of incandescent lamps and a label called 2850K (or possibly 2700K) compact fluorescent lamp, it just indicates their color map, is generally consistent, but on the light color (color map, and light color still has the distinction of) the evaluation of the color perception still have subtle differences: because of their different spectral composition, light emitted by incandescent lamps like watercolor of cobalt yellow or cadmium yellow, tonal "loud" and "transparent"; compact fluorescent lamp light resembles earth tones of yellow, some muddy.　　(2) therefore, the lighting design to specifically choose the illumination light source category, under the same conditions, to integrated weighing their luminous flux, average life-saving, on whether it is easy to maintain and a choice between a light color, because of the "green lighting" (I called for a "green light" to the specific analysis of treatment), but not an incandescent lamp.　　(3) the senior hotel, energy efficiency and ease of maintenance is important, for example, there is a good average life expectancy of compact fluorescent lamp achieves 10000 hours (but only one-tenth of its incandescent lamps), although Hotel eliminates the cost of replacing the lamp, but at the expense of the "pure" light and color. (4) as regards energy efficiency and extended lamp life of current domestic situation, a large part of the headquarters building as the Bank of China, combined with natural lighting and guest activities on brightness, through intelligent control systems in a timely manner to adjust light, to be addressed.　　Of course, there are many energy-saving method, but is beyond the scope of this article. 1.3 pay special attention to color temperature and luminance of the color using the illuminance and matching, meticulous and create appropriate space atmosphere. Generally speaking, color temperature and luminance to be in direct proportion to the match, that is, high intensity, high color temperature, and vice versa. Domestic hotel lighting design habits often, color temperature, illumination and generally low, often in the following figure represents a "dismal" atmosphere.　　This design practice in the future, to give sufficient attention. 1.4 can direct lighting, indirect lighting are not adopted light tank is now in commercial space lighting is widely used, and even some flooding.　　With electric light source, lighting manufacturing technology, with direct lighting way has been able to avoid discomfort glare on the Visual, so unless decorative requirements, otherwise, do not use flux and wasted and does not facilitate the maintenance of various types of luminous Groove. 1.5 uses the same color temperature of light sources, avoid the light color of disorganized same functional area, surface and objects, using color temperature consistent light source, optical environment in tone. Lighting design of the hotel, due to the stresses of not conflict and dramatic, so that uniform tone is consistent with the characteristics of the hotel. We note that some do very good interior design company, at this point still has many problems.　　For example, Guangzhou Jimei group design changlong, other hotel projects are very good, there are still a few problems: the lighting of a room with a cool white light; some rooms have warm white light and cool white light source, make people feel uncomfortable. 1.6 flux selection luminaire high utilization rate (1) selection parameters optimized design, high luminous flux utilization luminaires. We often come across such a situation, light the nominal luminous flux is very high, but due to the use of luminous flux of the lamp output efficiency low, theoretically calculation of illuminance values and actual finished, use Lux meter measured results quite different.　　(2) recommended that manufacturers of lamps and luminaires provide the efficiency parameters of photometric curve parameters, such as suspected, to delegate a related test equipment units for testing. 1.7 select suitable light distribution point for wine different functional areas of the room, the light distribution of the light intensity distribution curve, Centre of light intensity and half intensity, photometric parameters to be screened in order to avoid the two aspects of the luminous flux loss. (1) for example, the point is typically located in the lobby of the buildingPodium of the ceiling are usually very high, tall 6m above is very common to use a narrow beam angle, lighting distance long luminaries, not very bright, while the upper floor and ground 1m Department human activity areas are insufficient brightness; (2) on the other hand, if the ceiling in the rooms, the shorter range from using such a luminous, the ground is very bright, but insufficient illumination of vertical surfaces.　　The following figure is a PAR38/80W/beam angle 120 and PAR56 300W/beam angle/400 in comparison with light. (1) the colouration of general use CIE color index to evaluation, it is to include people of colour, 10 several color, used to evaluate lighting and standard light source (full light overcast sky) color display of evaluation.　　Generally speaking, the higher one light source Ra, indicating that it is the color of the better. (2) it should be noted that, because Ra takes the average of the sample, therefore, although some light source color index is very high, but on a specific color appearance may not be good.　　This will cause the lighting design of the hotel. (3) domestic lighting standards and design practice, has been neither on colour, usually emphasize attach too much importance to the good judge demanded that need high color index of the light source.　　Solid not, most people have more contact with the place, especially in the hotel, guests are able to show a healthy complexion is very important. (4) in addition, the color of good light source than the color of poor, under the same conditions, can have a low illumination.　　This is not to say that coloration can substitute part of illumination, but in some sense to sharp.　　Hotel lighting focus much more than the above, this article only relates to the author believes that currently lighting design practice is more prominent issues for lighting design Associates thought, discussion. 2. tap feature area lighting design room space variable hotel rooms should be at home, quiet, comfortable and cordial tone is typical. (1) illumination requirements: General lighting takes 50-100Lux, room illumination lower, to reflect the quiet, rest and even lazy characteristics; however, partial lighting, such as dressing mirror lighting, bedside reading lighting should provide sufficient illumination, these regional desirable 300Lux illuminance values; the most overlooked is the lighting desk writing, there are also fresh hotel offers a writing desk lamp (usually with decorative lamp instead of) to the guest, I lived in, the hotel is also only Sunshine Hotel Shenzhen possess such lighting, this is a very user-friendly lighting.　　(2) color temperature requirements: 3000K. Bedroom lights with 3500K following, in the bathroom lights with 3500K above. In the bedroom you need warm, high color temperature in the toilet needs to display a clean and crisp. (3) color requirements: Ra > 90. Better color rendering, making guests feel comfortable and increase self-confidence, good.
