First, the basic requirements of modern shopping mall lighting
Modern shopping malls, regardless of size, are considering the details of consumer buying behavior and psychological changes. Among these factors, the lighting environment is critical to shopping malls and consumers.
In order to ensure a high circulation rate of the crowd, the large space lighting of the mall requires a relatively high level of illumination of the base lighting. The level of illumination should be determined according to the economy, power supply and environment of the area where the mall is located. The recommended average illumination level is 500-1000lx, and the color rendering is Ra>80. In terms of light color, it is recommended to choose warm daylight or cool daylight according to different environments. In terms of function: first, The lighting of the mall should be able to display the unique image of the mall, so that customers can see the facilities and equipment of the store and the mall. This is the basic demand, including the lighting of the space and corridors. Second, the lighting needs to reflect the color of the goods more closely. Details such as texture, craftsmanship and quality can help customers clearly identify goods, understand the characteristics of goods, and even experience the special feelings that goods can bring to customers, such as clothing, jewelry, oil painting, etc. This is the key lighting part of shopping mall lighting. At the same time, save energy as much as possible in today's green environment.
Second, mall lighting trends <br> <br> With the development of lighting technology, the future of commercial lighting from the current sale of goods to meet the demand for lighting behavior become to provide consumers with a better shopping experience and the appropriate configuration Lighting system. The lighting system will create a relaxed and exciting experience environment for the better interaction between buyers and sellers to meet the emotional needs of people.
A more user-friendly shopping environment helps store owners in the mall to provide consumers with a more comfortable shopping experience. A harmonious and quiet lighting environment with warm and comfortable natural light allows consumers to make natural purchase decisions based on their own situation without buying pressure. The whole purchase has been made. 
Cheng seems to be relaxed and happy, just like a party to a friend.
Third, innovative products to promote commercial lighting upgrade program <br> <br> With the development of science and technology of lighting, mall lighting solutions are a combination of escalating. The traditional way of fluorescent tubes and ordinary halogen lamps dominated the world, due to the disadvantages of poor lighting and high power consumption, there are more and more alternatives in modern shopping mall lighting solutions. The new generation of energy-saving lighting products represented by ceramic metal halide lamps and discrete energy-saving lamps provide a solid foundation for the emergence of innovative lighting solutions. Excellent product performance, energy saving, especially suitable for shopping mall lighting with high lighting requirements and long lighting time. Below, briefly analyze the two new systems:
1. Ceramic metal halide lamp system 
The CDM ceramic metal halide lamp series pioneered by Philips represents the highest technology in today's light source industry and explains the new concept of commercial lighting. Ceramic metal halide lamps are popular for their stable natural light color, high luminous efficiency, long life, UV protection, effective protection of products and compact shape design. Coupled with a dedicated electronic ballast, the overall system provides better energy savings and longer life. Therefore, more and more high-end shopping malls have begun to use ceramic metal halide lamps to replace some of the tungsten halogen lamps to create tungsten halogen lamps, which can not provide dazzling light and strange display effects, and make up for the high-temperature lighting of tungsten halogen lamps, such as high temperature. Some defects such as the object being easily faded.
Take the Philips ceramic metal halide lamp product CDM-T as an example. This product has all the above characteristics, and there are two kinds of light colors, warm white and white light, which can make up for the deficiency of halogen yellow color. Warm white produces comfortable and warm lighting effects for fashion stores; white light produces lively, bright and modern lighting effects for sporting goods stores.
Ceramic metal halide lamps use polycrystalline alumina (PCA) as the main material of the bulb, with good chemical stability and thermal stability, plus high pressure halide vapor, which makes the color of the lamp better; The luminous material of the efficiency greatly improves the luminous efficiency, greatly saves the power consumption, and saves 4-6 times more energy than the ordinary halogen lamp; the arc tube filling material has stable properties, high lumen maintenance rate, and 6000 hours of light is used. The pass-through rate is still over 80%; advanced ceramic discharge tubes and electronic control technology and unique lead design ensure optimum color temperature stability and longevity.
characteristic | power | Voltage | Color temperature | Color rendering index | Light effect | Luminous flux | life | Electric appliance |
parameter | 35-250W | 88-96V | 3000-4200K | Ra=80～96 | 87-95Lm/w | 3300-23000Lm | >6000-12000h | EH-S |

2, "separate" energy-saving lamp series "separate" energy-saving lamps with its special lamp bridge position, advanced top coating process, the overall efficiency is increased by 18% than the traditional lamp. Correspondingly, the luminous flux and lumen maintenance rate of the lamp tube are greatly improved; the combination with the dedicated TLD electronic ballast saves more than 80% of the energy of the ordinary incandescent lamp; the trichromatic rare earth phosphor used and the special formula are used. The color index reaches 80 or more, the color reproduction is better, the object to be photographed is more realistic and the level is more distinct; the built-in anti-interference capacitor and the starter have no noise and no flicker; the special lamp head is easy to install, convenient for maintenance and maintenance; It has low heat generation, saves air conditioning and electricity, and is suitable for a variety of closed and open lamps.
Fourth, the new lighting plan example - Wuhan World Trade Center sell goods selling goods <br> <br> Wuhan World Trade Center is located in Wuhan Inner Ring Road, covers an area of 60,000 square meters, with a total construction area of 200,000 square meters. As a typical shop-in-shop sales, it takes Wal-Mart Supermarket and China Merchants Department Store as the leading products, and integrates more than 700 various franchise stores such as Pizza Hut, KFC, McDonald's, Watsons, and Xinhua Bookstore to form a A large-scale commercial center that combines shopping, dining, and entertainment.
Zhongshang Department Store is mainly based on “separate†energy-saving lamps. Partially using Philips ceramic metal halide lamp system and tungsten halogen lamp system for key lighting, precise light control, uniform light and natural soft lighting colors reflect the characteristics of modern high-end fashion department stores. . Wal-Mart supermarkets mainly focus on lighting, and some special areas such as food areas use ceramic metal halide lamp system for key lighting, reflecting high illumination, high color rendering, simple and bright modern supermarket style.
Other special store lighting is closely combined with its own characteristics, using different forms of lamps, or splendid, or warm and romantic, or simple and generous, or small and exquisite; public area walkway with hidden lights and energy-saving downlight lighting, play a good guide and points As the center of the sales and trade shop, the atrium is equipped with Philips ceramic metal halide lamp and supplemented by Philips halogen tungsten lamp series. It realizes the combination of virtual and real, dynamic and static lighting effects, with strong visual impact and shopping. comfortability.
In the lighting design of sales and trade, the basic connotation of green lighting project is always reflected: energy saving, high efficiency, comfort, safety and environmental protection.
Conclusion:
As large-scale complex shopping malls become the mainstream of the development of large and medium-sized cities in China, how to find a reasonable design plan among the various lighting indicators will become the problem faced by the owners of these shopping malls. The new solution can stimulate customers to buy more products. Secondly, it can reduce the operating temperature by reducing the lighting temperature and reducing the lighting temperature to reduce operating costs. It has a broad space for development.
