Fourth, the characteristics of commercial lighting
1. The visibility and attractiveness of attractive goods is very important to illuminate specific objects, enhance their image and emphasize them, making them the focus of attention.
2, comfortable light environment In order to attract customers, the mall must create a comfortable light environment, if a customer feels comfortable when shopping, they will stay longer, spend more money, and are willing to come back and forth again and again. Quality lighting evokes emotions and feelings, which in turn strengthens the store's brand. 5. Classification of commercial lighting Basic lighting | Provide basic functional lighting | Key lighting (showcase and window lighting) | Reasonable accent lighting can create a variety of contrast effects, emphasizing the shape, texture and color of the product, enhancing the visibility and appeal of the product, attracting more eyeballs | Ambient lighting | Create a comfortable light environment and express the emotions of the space |
Sixth, specific lighting methods and lamps checkout counter | Meet operational requirements | | Display window lighting | Impress the customer with dramatic, use white glare or color light to attract the passer through evenly saturated lighting | | Display cabinet lighting | Illuminate items in glass cabinets or open containers and shelves | | Peripheral lighting | Helps limit the sale of merchandise and provides the necessary vertical lighting along the wall to make the space feel bigger overall, with the aim of attracting customers from the main channel to the sales area | | Ceiling lighting | Expanded the space, increased the height of the ceiling, and created a sense of openness and space through the lines formed by long, unshaded, uninterrupted light. | | Fitting room lighting | The form and texture of the product should be clearly displayed so that the color of the product is truly natural | | Supporting space (warehouse, staff lounge) | standard | | Indicating lighting | Make shopping flow convenient for customers | |

Nine, the elements that commercial lighting needs to grasp
Due to the complexity of the store itself, in addition to the basic illumination, in addition to the basic illumination, it is necessary to consider various key lightings that are compatible with the actual environmental requirements. The two are harmonious and unified to create an excellent overall illumination. effect. Influencing factors on lighting effects Illuminance | Color temperature | Light distribution | Color rendering |
9.1
The different illuminances of different regions or commodities form customers' different feelings for goods and spaces, which in turn creates a sense of spatial pleasure and comfort. (The change in brightness of the ceiling and vertical surfaces plays a crucial role in the formation of feelings.) In Philips' standards, there is a scientific summary of the brightness ratio of goods and the environment and the sensory effect on people.
(See attached table 3.5) 9.2 Relationship between color temperature and illuminance
The store lighting design creates a personalized store space through the combination of color temperature and illumination. High illumination and high color temperature | Comfortable | Supermarket | Low illumination low color temperature | Comfortable | Jewelry store | High illumination low color temperature | Uncomfortable (sad and hot) | Low illumination and high color temperature | Uncomfortable (cool) |
9.3 Color rendering
The use of high color rendering (Ra > 80) light sources in stores is a basic store principle, but sometimes it is desirable to use a (glamorous) color development method to create some color differences compared to a fully faithful representation.
a. faithful reproduction of color b. compared with the reference source to produce some color difference, if it is the color difference produced in the ideal direction can be used 9.4
Only by fully grasping the color and reflectivity of the floor, wall, ceiling, and the material color of the product and the different light distribution of the lamp can produce various effects. Close range | Wide light distribution | Long distance | Narrow light distribution | Close range, dramatic effect | Narrow light distribution |
X. The process of commercial lighting design 1. Conception | Owner's request | Architectural design requirements | The nature of the store | Surroundings | Confirm budget | 2. Determination principle | Set lighting concept | Imagine the distribution of spatial light | Definition of each region | 3. basic design | Basic lighting | Lighting technique, illumination | Lamp, light source | Commodity lighting | Spatial light distribution | Ambient lighting | | 4. Implementation design | Illumination calculation is carried out by lighting software to determine the number of lamps, confirmation and adjustment of illumination, determine the feasibility of the budget, and make construction drawings. | 5. construction | On-site, re-confirmation of design, supervision of construction lighting commissioning, collection of various data |
Eleven, the development trend of Shanglai lighting
1. Provides flexible control methods to increase lighting levels in a specified area, at specific times, to accommodate changes in merchandise placement.
2. Produce different working modes and implement different lighting methods at different times
Before opening the store | | Business hours | | at night | | late at night | | four Seasons | |
3. Produces dynamic or special lighting effects, although general effects lighting can produce special effects. But having control of dynamic lighting can produce more fun.
4. The most energy-efficient lighting uses the least amount of energy, the shortest time of exercise |
