We often say that food has an appetite first. Then investigate the root, where does the appetite come from?
The appetite of a person is first derived from the perception of the "color" of food. Just like many people hate the sound of fingernails rubbing the tabletop, it is because of the fear of the ancient carnivorous animal's teeth and the sound of human flesh and blood. People's illumination of food is a survival instinct that is inherited by ancestors.
â–² different fresh products, using different light effects
With the development of the fresh food industry, fresh lighting has also risen with the trend, and the trend of fresh consumption has shifted to Dashang. As we all know, the special fresh light, generally with 2700K light source, Ra> 80, R9> 60, this is common sense. But is fresh lighting just like this? Please listen slowly.
People's perception of the "color" of food has been engraved into the DNA of the human body through every evolution of human beings. No one has noticed it, but it is. Light, which determines people's perception of food, the color, likes and dislikes reflected by light, has been decided at the moment of witness.
The biggest effect of the fresh light is to restore the original color of the food. As we all know, the coloration of sunlight is the best. The ancient humans distinguish the characteristics of food in the sunlight. Therefore, lamps with high color rendering and close to sunlight illuminate food, which will make people feel safe and the body will naturally produce appetite. Secrete dopamine. Natural light penetrates through the window, and natural light makes the food more appetizing. From the enticing photos of friends, you can already see the ultimate light and shadow art of fresh lighting.
The lighting in the fresh area is generally hierarchical. In addition to the lighting of the ambient lighting, there are various kinds of lighting on the shelves. Therefore, under these white lights, in order to reflect the characteristics of various products, the color temperature of the lights selected by each category, It also varies. But another major premise is that LED lights will be used (because LED fresh lights have high color rendering, power saving, good brightness, low light decay, and low heat).
â–² fluorescent, incandescent, natural light under the same item
It is better to use LED lighting, which is related to the color temperature of the lamp. Generally, the green light in the vegetable area will appear fresh and green;
The meat area uses a color temperature of 1800K, Ra>80, which can better express red, brown and orange, making the meat more delicious;
Bread, snacks and other foods, generally use color temperature 2500K, Ra> 80, which can better express yellow, so that the baked products create a soft and soft feeling, as if you can smell a wheat flavor;
In the freezing area, the lighting and baking area are exactly the opposite. In order to display the fresh, the freezing area should use light to create a frozen feeling. The color temperature is 4200K, Ra>90, which makes the products in the fresh area brighter, whiter and more natural. It is like a frozen fish that the Eskimos cut out from the ice. It hits the winter night, is frozen from the moment, and then is salvaged and presented on the table.
â–²Different fresh foods have different optimal color temperatures
â–²The same fruit, different color renderings make the appetite different
The ratio of each color is not necessarily a fixed value, and each person's aesthetic vision is different, so the color preference and cognition are also different. However, after thousands of years of truth test, the fixed procedure for fresh lighting has been written in the human bones. Whether it is admitted or not, the general direction of fresh lighting will not have much subversion. Speaking of this, think of the people's lighting in the past fire, this is actually part of the human lighting.
For the time being, we will talk about the details of the light source. Let's talk about the big environment of fresh lighting. Does fresh lighting need no need for accent lighting? What should be done with key lighting?
As mentioned earlier, you can give a positive answer. Fresh lighting is a must to focus on lighting, the height of the light source, the level of lighting and so on, are a good and bad details of fresh lighting.
Ordinary commercial super lighting, to meet the functionality of Shangchao, so the ambient light requires high illumination, allowing consumers to observe the material of the product and feel the sanitation. The first sense of "white = health" is an instinctual understanding that humans and germs have struggled for thousands of years. However, with the discovery and application of penicillin, human beings have new requirements for food, that is, to be "good" and to have a taste.
Therefore, in addition to the sense of environmental sanitation, the advanced commercial super-lighting adds a lot of caution to increase the texture of the object through accent lighting. The ambient light that acts as the basic lighting is dominated by white light, and the illumination is moderate, creating a clean and comfortable shopping environment. And various shelves have set up key lighting, supplementing the illumination of ambient light, and a variety of light effects are brought together to show the product texture according to local conditions.
â–²The common lighting method in the fresh area
Normally, the shelf-based lighting selects a fresh light of 20W~40W, and then selects a spotlight of about 20W for accent lighting. Nowadays, the general Shangchao, in order to facilitate the lighting control, mostly adopts the combination of the rail light and the spotlight, but in the fresh area, the rail light and the spotlight are converted into a fresh special version, so as to ensure the overall coordination of the supermarket, Easy to install. This type of lighting also has merit.
However, in fact, the height and color temperature of the light source will cause different light and shadow. Fruits and frozen fresh can be used as the key lighting. When the color temperature is matched, the wide and narrow combination of lighting can make the surface of the object more full and smooth, cover a lot of defects, and the quality of the items is higher.
â–² different fresh and different lighting and lighting effects
In addition to the color of meat and baked goods, the texture also determines whether people have appetite for them. Therefore, more changes can adjust the light source of the hanging wire, can adjust the light and shadow to the best angle, create a more refined light environment, show the texture of the product, is the first choice for high-end business. The hoisting light source is closer to the item, and more consideration should be given to the use of LED fresh light without radiation damage, which will not generate excess heat and ensure fresh freshness.
Each space has its own unique light and shadow. The lighting design is like a painter. It just means that our pen is light, and the scene of painting is not paper but space.
Therefore, to say the height distance of the light source, there is no fixed template, based on the designer's understanding of the product, relying on their own beauty and designer intuition to grasp. After all, we are lighting designers, not lighting installers.
The illuminating accent lighting also requires that the spot is uniform and not glare, and the beam angle can be optimally 70°, so that the accent lighting between the two adjacent two areas does not interfere with each other.
All human behaviors can find answers in history, and the traces of the years will be confirmed in the genes, we call instinct. Lighting design is a very magical career. Whether it is from the Kuafu to the Prometheus to steal the fire to bring the light and heat to the world, or the original man to get a fire, to leave a safe territory in the night to avoid the history of the beast attack. Illumination, falling into the hands of human beings from the realm of God, is still working hard to make the light source in hand close to the light made by God. Illumination witnessed the rise of mankind and practiced human beings from animals to God.
When we are doing lighting design, when we talk about human lighting, do you think this is really a very fresh idea? In fact, we have been studying an ancient proposition, just as we look up at the stars and ask, "Where do people come from?", we talk about lighting design, in fact, we are studying "Where does light come from, how do we apply it?" Human illumination is the study of human genes and research history on the human genome.
You look out the window, the neon city, in the hall of the feast, the intertwined lights are shining, the answer we are looking for is here.
