The lighting design of hotel space should fully mobilize all the characteristics of light, and combine the various functions of the hotel and the design concept of star-rated hotels. 1. Lobby: Lobby space is mainly divided into lobby entrance, main hall, service desk and rest area. The lighting in this area should be consistent, and warm light sources should be used to form an interesting, continuous and undulating transition of light and shade through brightness contrast, so as to create a cordial welcoming atmosphere as a whole. 2. Entrance to the lobby: The entrance to the lobby includes the entrance and the front hall, which is a transitional space for entering the hotel. It is necessary to give the guests a clear guide to show the entrance position. In addition to creating a comfortable visual environment, we should also emphasize its friendly atmosphere. Here, energy-saving downlights are used to provide basic functional lighting. In addition, indirect lighting can be used to hide T4 and T5 tubes in the ceiling groove structure. By illuminating the ceiling structure, the spatial layering of this area is enriched and a good first impression is left to customers. 3. Lobby main hall: The main hall is the place where the hotel provides guests with waiting and communication, and it is also an important place to reflect the hotel's grade and attract guests to stay. It pays more attention to strong decoration in space. Here, the horizontal plane can reach a higher brightness (illuminance is 311LUX) by evenly distributing lights. The main hall of a star-rated hotel can consider the application of natural lighting, and at the same time, it should pay attention to the coordination with the overall decorative environment when using artificial lighting. In order to enable customers to clearly see each other's expressions and details in communication, we can use grille downlights as accent lighting, and emphasize the decorative quality of star-rated hotels through hidden lamps and wall lamps. 4. Lobby service desk area: The lighting in the service desk area is required to be relatively bright in the whole lobby to achieve eye-catching effect, and the illumination level is higher than other areas. In order to avoid glare, the lighting mode of the service desk adopts a hidden light source with high color rendering, which is convenient for communication between guests and receptionists, as well as accurate and fast formalities. Chain hotels should also strengthen the illumination of their chain store signs and background walls; The reception area of star-rated hotels is generally large, so it is necessary to pay attention to its decoration style, use recessed lamps and table lamps as local lighting and wall lamps as decorative lighting, and ensure that the style and color of lamps are consistent with the decorative environment. 5. Lobby/Lounge: Lounge often incorporates some unique elements, such as humanistic elements, theme elements and decorative elements. Lighting application should consider not only functionality, but also artistry and moderate brightness. Energy-saving downlights with warm yellow light (3111K) and strong color reducibility (color rendering Ra 81) are used as basic lighting and ceiling lamps as auxiliary lighting. In order to reflect the rest function and pay attention to the control of glare, it is best to choose light source hidden lamps. The lighting in the rest area of star-rated hotels should be layered, at the same time, it should be consistent with the surrounding environment and pay attention to the perfect integration of decorative style and lighting; Energy-saving downlights are used as basic lighting, and light sources with warm yellow light (3111K) and high color rendering (Ra 91) are equipped. The ceiling lamp is used as auxiliary lighting, and the dark trough lamp is used as scene lighting, highlighting the top space level; As decorative lighting, floor lamp reflects the taste of the hotel. 6. Elevator Hall: The lighting of elevator hall adopts a combination of functional and decorative lighting. Here, you can choose a wide downlight to illuminate the whole environment, combine a narrow downlight or a ceiling lamp to apply accent lighting to the elevator entrance, and choose a light source of 4311K (warm white light). The bright lighting environment has the function of indicating and brings customers a sense of security. In order to shape the style and taste, and at the same time to ensure the integrity with other spaces, star-rated hotels can increase decorative lighting methods such as wall lamps and ceiling sinks. 7. Channel area: Channel lighting mainly focuses on guidance and safety. Proper illumination and color temperature not only make guests feel safe, but also create a warm and cordial atmosphere; Adopt energy-saving downlight as basic lighting, which reflects the requirements of guidance and safety; In order to make the passage space vivid, decorative paintings or handicrafts are usually installed on the wall; The use of ceiling lanterns as accent lighting plays an important role in emphasizing sight. The corridor of chain hotels is generally narrow, and an extended light trough can be added at the top. Star hotels can add decorative wall lamps on both sides, and wall lamps also play a guiding role. Hidden trough lights are hidden in the ceiling to increase the brightness and sense of space of the passage. 8. Guest Room/Bedroom: The guest room is the core area of the hotel and should be as friendly as home. Here is mainly rest, and anti-glare is also very important in guest rooms; Lighting should reflect warmth and ease, and achieve tranquility and comfort with relatively low illumination. Desk lamp is used as local lighting to facilitate the processing of business documents; Mirror headlights with good color rendering are used for the lighting in front of the dressing mirror; Bedside reading lighting can use wall lamp or desk lamp, equipped with adjustable light source. 9. Guest room/bathroom: The lighting in the bathroom should be soft and uniform, and should be combined with ordinary lighting and front-of-mirror lighting to create a refreshing and clean bathroom and meet the local lighting requirements; Use anti-fog downlights or ceiling lamps to complete basic lighting, and use energy-saving downlights combined with anti-fog ceiling lamps to cooperate with local lighting, with relatively high illumination requirements (311 lux); A ceiling lamp can be installed right in front of the toilet to facilitate reading; Above the bathtub, the fog-proof downlight is used as basic lighting, and the sink can be partially illuminated by downlight or spotlight; The illuminance of mirror headlights should be above 281 LUX. 11. Dining area/Chinese food: The illumination of Chinese restaurants is much higher than that of western restaurants, but the brightness contrast should not be too strong and the light should be uniform. Point light source, strip light source or various types of chandeliers can meet good lighting requirements. The table top is illuminated by lamps with high color rendering, which truly restores the quality and color tone of dishes and arouses customers' appetite. The quality of Chinese food in star-rated hotels is relatively high, and the lighting should be three-dimensional. In the application of restaurant lighting, wall lamps or projection lamps are used to correct the planarization of general lighting and create a high-taste dining environment. 11. Dining area/Western food: Western-style restaurants should combine Western culture and dining habits. The overall lighting atmosphere should be warm and emotional, and the brightness is generally lower than that of Chinese restaurants. The table top uses high color-rendering lamps for accent lighting, which highlights the color of dishes and enhances the appetite of diners. 12. Dining area/multi-function hall: The multi-function hall integrates functions such as banquet and meeting, and attention should be paid to the collocation of overall lighting, local lighting and accent lighting. Overall lighting needs to grasp the indoor lighting environment of the hotel, including brightness, light source type, light color, etc. In accent lighting, lamps that can flexibly adjust the illumination angle are often used to realize the lighting transformation effect of different scenes. The multifunctional hall should be equipped with intelligent dimming system to realize the switching of different use scenes. The lighting design of multi-function hall in star-rated hotels is closely related to the decoration style and grade, and the lamps with adjustable angle and high power are mainly used in the selection of lamps. 13. Recreation and entertainment area/coffee bar/bar: Lighting mainly shows the rendering of the atmosphere of leisure and entertainment environment, and the overall brightness should not be too high. The lighting effect combining static and dynamic makes the space more vivid. The unique spirituality of lighting will shape the unique charm of cafes and bars and arouse people's yearning for tranquility. Here, grating spotlights can be used to meet the basic functional lighting; As a accent lighting, the ceiling lantern creates a soft coffee shop and a deep sense of space in the bar. The lighting requirements of leisure and entertainment areas in star-rated hotels can better render the atmosphere. It is suggested to use flexible lighting fixtures, recessed lights and decorative lights to create a unique style and taste. Different types of lamps and lanterns In addition, for star-rated hotels, the types and demands of lamps and lanterns are different from those of ordinary hotels. Starting from the characteristics and needs of star-rated hotels, there are several main considerations, which are the main points that we need to pay attention to when designing hotel lighting: 1. Timeliness and durability. Generally, a star-rated hotel needs a small renovation and maintenance every five years and a large renovation and maintenance every ten years. In other words, the life of lamps must be at least ten years or more to meet the requirements of star-rated hotels. Because ordinary minor maintenance will not replace lamps and lanterns, the scope of human resources involved is too large. This means that in the selection of lamps, the quality of the most heated and compressed parts of lamps, including reflective cup cover, heat dissipation components and fixed (positioning) components, is very important. 2. Flexibility Generally, the light source used in star-rated hotels has a service life of about 2,111 to 4,111 hours. Therefore, in 2111, lamps and lanterns will need to be replaced many times. The number of lamps in star-rated hotels is over 11,111, so the replacement of light sources also involves huge human resources, so the flexibility of lamps is another consideration. The most ideal lamp selection is that the light source can be loaded and unloaded without affecting the fixed (positioning) components of the lamp. This can not only save the replacement time, but also protect the interior decoration positively. 3, detailed modeling This includes all aspects of the lamp itself. Take the general ceiling downlight as an example, we should pay attention to the details such as the spraying quality of its trim (if it is metal, what is the surface quality), the smoothness of the reflective cup (if it is frosted reflective cup, the uniformity of sand spraying), and the joint tightness (whether there is light leakage) with the ceiling surface (gypsum board/wood veneer) after the lamp is installed in ceiling. One more thing, I need to mention by the way, besides the hardware (lamps), the installer (technology) is also very important, and the decoration should ensure that the lamps are installed in the correct installation method. 4. The Cutoff Angle of the light projection index lamps, the glare effect, how to collect the light sources, the elasticity of the projection direction of the lamps, and the expandability of the accessories all affect the selection of lamps. In particular, the expandability of accessories should be considered very carefully, because most of the accessories such as "projection angle", "color/tone correction", "glare prevention" and "accurate projection/lighting" in controlling the projection index rely on these accessories to create the overall atmosphere. The same appeal From the environmental considerations of hotel lighting design, whether it is domestic or foreign hotel lighting design in the future, it is definitely inseparable from the premise of "environmental protection". Whether it is market demand or design development, it is inseparable from this concept of "environmental protection". "Environmental protection" in market demand can be interpreted as environmental protection in equipment, that is, how to balance various factors that cause pollution. This is also an important responsibility of lighting designers. Including: 1, power consumption: resulting in the production of carbon dioxide, increasing greenhouse emissions. 2. Light source life/lamp life: the time that can serve the project. 3. Discarding pollution: Although the life of tungsten wire or halogen light source is relatively short, the substances contained in it have less pollution to the environment. On the contrary, such as energy-saving tubes, the life is longer than halogen, but when abandoned, it will pollute the environment to a higher degree. At present, if the investment cost is not considered, LED will be a more environmentally friendly light source choice. 4. Heat of light source: The heat generated by light source/lamp increases the load of air conditioner. 5. Light pollution: In addition to avoiding excessive lighting, we should also start from the design concept and cooperate with the special accessories of lamps to control the projection of light as much as possible and collect unnecessary light in lamps. To sum up the above points, I suggest that lighting designers should work together with lighting engineers, architects and physicists to discuss and study a comprehensive environmental protection index, and make an objective environmental protection scoring standard for lamps, which can be provided to consultants and manufacturers.
