Large shopping mall LED design scheme

　　Overview

In product display, products and brands are the center and soul of the store, and all the equipment in the store is served around these two centers. A good lighting environment can attract and guide the flow of people, and a well-designed lighting environment can save energy and control operating costs. The good color rendering of the light source can show the high-quality materials, exquisite design, and rich colors of clothing, which can become a catalyst for customers to purchase decisions, and play the role of a silent salesman.

In commodity display, good lighting design can attract consumers to patronize and guide the flow of people, clearly display the color and texture of commodities, create a more relaxed and comfortable shopping environment, and greatly save electricity bills (not only can save energy consumption in lighting, And can save air-conditioning costs), control operating costs.

　　1. Elements that must be considered in the lighting design of shopping malls

Illumination analysis

For the lighting design of comprehensive large-scale commercial centers, it is necessary to pay attention to the overall illuminance, local illuminance and the ratio of local and overall illuminance. The illuminance of general supermarkets and super shopping malls is 500-750 lux, and any other location is 300-500 lux. The average illuminance of general lighting in shopping malls in big cities in my country is 300-500-750 lux, and the recommended value is 500 lux. But the stores of different products will be different. Such as high-value commodities, fashion, jewelry and other sales areas, the illumination is relatively high, while the sales areas of crude low-value commodities, vegetables and daily food, and other sales areas, the illumination is slightly lower.

Color temperature analysis

Lighting colors are divided into cool tones and warm tones, including red, green, blue and other colors. In the lighting design of shopping malls, warm color temperature (below 3300K) or intermediate color temperature (3300-5300K) is usually appropriate. However, for most shopping malls with moderate illumination levels, it is more appropriate to use an intermediate color temperature of about 3500-4000K; generally speaking, low color temperature and high illumination are easy to create a sultry atmosphere, and high color temperature and low illumination are easy to create a cold atmosphere.

Color rendering index

Most products require good color rendering. According to the recommendation of CIE "Indoor Lighting Guide", the color rendering index of shopping mall lighting should be 1B level (ie 90>Ra≥80). This is very necessary for customers to correctly identify the color and texture of the product and choose the product that meets their wishes. If the color rendering index of the light source is too low, the product will lose its true sense of color and characteristics.

　　2. Lighting design guidance for key functional areas

entrance

The entrance is the main road of the commercial store, and it is the first impression of consumers on the grade and positioning of the store. Good entrance lighting should be guiding, interesting and show the grade of the store, which can arouse consumers' consumption awareness, and the bright space also makes consumers feel safe. For example, the entrance and exit generally have a large flow of people. For safety reasons, the brightness of the basic lighting at the entrance is higher than that of other areas, which makes people feel more comfortable when entering the lobby. If some floor lamps can be properly installed, it will have a better guiding effect on consumers.

Atrium Plaza

The atrium is the focal point of the shopping center. In addition to its essential functions such as sight guidance, rest, display, and performance, it is also an important spatial indicator. The space feature of the atrium is different from that of the business space to attract the attention of shoppers and also to let shoppers understand their position in the space. At the same time, the atrium is also an excellent place to shape the corporate image, because it is usually the meeting point of shopping routes, and it is also the end point of shopping routes.

Therefore, the lighting design of the atrium should have a certain degree of artistry, decorate the space and create a comfortable light environment. In the design, attention should be paid to the consideration of natural lighting, and artificial lighting should be relied on for business at night. On the top of the higher atrium, the lighting of the wall can enrich the space level. The color temperature can also be more diversified due to the spatial characteristics, and the average illuminance design should be around 300lux.

  Escalator

In all kinds of commercial stores, escalators play a vital role in transporting passengers. It can smoothly connect different areas together, providing passengers with convenient access from the parking lot to the various shopping floors. Therefore, the lighting of the escalator mainly comes from the lighting devices in the surrounding places. At the same time, the lighting fixtures should be properly installed above the elevator, so that the passengers can clearly identify the elevator warning line.

  corridor

Corridor is a passage connecting different areas. It is used frequently and needs to have a more uniform illumination and a certain brightness. At the same time, attention should be paid to the coordination with the lighting of other independent stores. Otherwise, it will be darker from the bright corridor. area, it can cause depression or discomfort. The lighting of the corridor should also have a certain orientation, which can be suggested by the arrangement of the lamps.

  promotion area

The establishment of the promotion area is, on the one hand, to increase the sales of goods by way of profit-making; Therefore, the display of goods in the promotion area must immediately attract the attention of consumers. In addition to the vivid display of commodities, lighting shoulders the important task of grabbing the attention of consumers. Generally speaking, the brightness of the promotion area should be higher than 20% of the surrounding environment.

  rest area

The setting of the lounge area is very important. Warm lighting and beautiful music make the guests staying here get a small drink and a moment of rest. Consumers who get "fueled" on the lounge chair are likely to stroll for half an hour, which will create new sales increments for merchants.

The comfortable and elegant rest area brings consumers a kind of enjoyment. The lighting of the space should be lighting with high color rendering, low color temperature and low illuminance, and lamps with good anti-glare performance should be selected. The average illuminance design should be around 200lux.

　　3. Lighting applications in supermarkets

Shelf area

The shelf area is the main body of supermarket merchandise display, which requires both horizontal and vertical lighting, so that all merchandise has enough opportunities to be purchased by consumers. Therefore, shelf area lighting is the best embodiment of lighting technology. Due to the short distance between the shelves, the lighting should be based on the principle of avoiding shadows and making it easy to find products. Fluorescent lamp brackets with masks or anti-glare series grille light panels can be used between the shelves as the main lighting, and the color temperature should be neutral. 4300K, the average illumination reaches more than 300lux.

The lighting method of the height area of ​​different shelves (H=height):

H<6M generally adopts light strip lighting

6M≤H<8M mostly use point arrangement, the lights are between the shelves

H ≥ 8M, the arrangement of lamps can be ignored, but it is necessary to consider increasing the vertical illuminance on the shelf

Fresh fruit and vegetable area

The lighting in this area should not only ensure the perfect presentation of the products, but also consider the impact of temperature on the storage period of the products. It is not advisable to use lighting fixtures with too high calorific value here, which will cause the water loss of fresh fruits and make the fruits lose their freshness. It should be equipped with high color rendering cold light source lighting without ultraviolet and infrared radiation, and use low-power incandescent lamps with transparent masks as accent lighting. For example, the color temperature of the fruit area is better to choose a warm color of 3000K, and the vegetable area is to choose a cool color of about 6400K. The average illuminance should reach 300lux, and the illuminance in key areas should reach more than 500lux.

Deli area

This area has relatively independent containers and kitchen facilities. Lighting is required to display lighting equipment with good performance and restore the true color of food. For example, the choice of warm lighting can enhance the temptation of cooked food to consumers, and at the same time pay attention to temperature control, so as not to affect the preservation of goods. In the selection of lamps, a lamp panel with a diffuse reflection mask should be used as the basic lighting, and a low-power incandescent lamp with a transparent mask should be used as the accent lighting. The color temperature must be 3000K, the average illumination is 300lux, and the illumination in key areas is above 500lux.

Refrigeration area

The lighting in this area should be dominated by warm tones with high color rendering, so that customers have a good psychological effect that the food stored in this supermarket is very fresh, thereby stimulating a strong desire to shop. For food in the corner or bottom of the freezer, hidden LED linear lights can be used for lighting. The color temperature must be 3000K, the average illumination is 300lux, and the illumination in key areas is above 500lux.

  cashier

The cashier area should highlight the visual guidance for consumers, so that they can easily find the area and complete the purchase. In addition, the area usually has a large flow of people, and the cashiers are also in continuous high-intensity work. Therefore, it is most important for cashiers and consumers to be able to clearly see the goods and coins for cashiers, while ensuring that consumers can easily read the contents of the cashier slip. The color temperature should be 4300K, the average illumination should be above 300lux, and the illumination uniformity should be relatively high.
