Just as you have already passed the warmth of the age, you have already passed the age of filling your stomach.
In this era of experience-oriented, the lifeline of a restaurant, in addition to delicious, the feeling brought by space design and lighting design is also an important part of the diners' evaluation system.
It is even said that many times you remember that this restaurant is not a taste, but a longer lasting feeling than taste (memory). Therefore, the lighting design of the dining space plays a vital role in the operation of a restaurant.
Let's take a high-end cafeteria as an example to analyze the lighting design points of the dining space.
What is the per capita consumption of the restaurant? Target space positioning
When we go to find food, there are several key words, and “per capita consumption†is a very key word:
Figure: In the food keyword recommendation displayed in the public comment network, in addition to the number of stars and reviews, the third place is the keyword per capita consumption, which means that this keyword largely determines this The positioning of the space.
The catering store is first of all a store, and the store must first pay attention to the “Ping effect†of the operator. Simply put, how much rent is paid for one square meter? What do you sell by selling? How to sell? This is not a matter of wide management, it is precisely the vital item that needs to be paid attention to in commercial lighting design.
The positioning is wrong, everything done in the back is no good, for example: a medium and high-end restaurant and a fast food restaurant are not the same positioning, high-end focus on the dining experience, and fast food restaurants are fast-moving, pay attention to rapid flow, to achieve comparison High turndown rate. These two different positionings are definitely different for their lighting design or lighting design.
A high-end buffet restaurant located in Zhujiang New Town, the core CBD of Guangzhou, has a high-end positioning and luxurious interior design, so it is conceivable that dark and uneven light is the main theme of light in this space.
Let's take a look at the scene. Dark and uneven seems to be a keynote:
Picture: The light of the decoration, we see a lot of golden highlights, is a feeling close to golden yellow, creating a very good "expensive" feeling.
Analysis: In order to reflect the high-end positioning of the dining experience, lighting designers chose a lower 2700K color temperature in the overall tone of color temperature, creating a romantic and warm dining atmosphere.
And in order to reflect the overall tone of luxury retro, lighting designers choose the lamps from material to form to light and color, have achieved a corresponding fit. Reflecting the high-end luxury brass material, the retro candlestick lamp shape, with the large angle and low color temperature candle bubble, all in one, reminding people of the accurate positioning of the restaurant luxury retro.
Photo: A hotel in Dubai, the golden light color is the special color of the local tyrant, which is a common sense of psychological suggestion for the design of the light environment.
Can the food be seen clearly? Function lighting of the dining table
After the positioning of the restaurant is clear, the next thing that needs to be dissected is the realization of the lighting of various functional spaces.
In the cafeteria, there are two main categories of places to eat and place to eat.
The buffet dining table, the demand for light is inevitable: let everyone clearly see the dishes, easy to select at a glance, therefore, providing uniform high illumination, and focusing on the food display that needs to express beauty, is the main method .
Photo: Garden Hotel Lingxuan Pavilion buffet selection area.
Let's look at the lighting design of this project:
Analysis: The intensive brass candlestick lamp not only reflects the luxurious tone and the retro court style, but also enhances the illumination of the overall space of the dining table. It is dotted with the blue reflection of the ice sculpture below. Frozen seafood dishes are perfectly represented.
Good food is a beautiful person: the light of the dining area
In the dining area, the ratio of the light of the dining table to the ambient light is skillful. Different positioning and goals require different lighting expressions.
For the high-end stylish dining area, you only need to use a narrow beam of light to illuminate the table, and the reflected light illuminates the face. Let people communicate smoothly and present a warm and welcoming effect.
The cheap dining area of ​​civilians only needs to illuminate large spaces with wide beam angles, such as KFC, McDonald's, and real kungfu, which evenly illuminate the entire dining area and present an affinity feature.
The elegant and comfortable dining area is a narrow beam that illuminates the table and indirectly illuminates the rendering space, giving the space a comfortable atmosphere and a rich layering.
Take a look at this case as well:
Analysis: A high-end, sturdy restaurant in the dining area is responsible for illuminating the narrow beam of light on the table, as well as indirect lighting of the rendering space to create a comfortable dining environment.
In this case, the light responsible for illuminating the table is an adjustable angle spotlight embedded in the beam, and the narrow beam allows the light to be limited to the table to achieve an appetite-enhancing effect. The indirect lighting of the rendering space uses the retro palace style lighting that is consistent with the overall tone, which makes the whole dining space present a rich layering, creating a luxurious and comfortable atmosphere.
It looks so delicious: the light quality that has to be said
The design of the lighting, the good experience of the space depends to a large extent on the good light quality of the luminaire. Light quality is mainly reflected in the following four aspects: suitable color temperature, color rendering index (especially for red reduction index R9) and glare control.
Glare vs no glare
(The interference light in the left picture can cause people's discomfort, distraction or decreased visual ability, and customers will feel bored and resistive)
Let's take a look at the effects of lighting design in this case:
Analysis: It must be said that the designer's choice of lamps for the presentation of the food is wonderful, Ra is equal to 92 color rendering index, resulting in the best color reproduction, which is also the restaurant was listed as "the best buffet list" The important reason for the first place.
Product Description
SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.
Surge protective Device Model Selection
With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.
SPD for Power Supply System Series Selection Guide
The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
