With the increasingly fierce competition in the supermarket industry and the industry entering the era of low profit, how to reduce operating costs has become a problem that retail companies often think about. In particular, huge electricity bills have become an important part of supermarket costs. How to control electricity cost has become the key to energy-saving renovation in supermarkets. Some lighting experts pointed out that the consumption of electric energy accounts for 70% of the cost of lighting, while the equipment itself only accounts for 3% of the lighting cost (equipment maintenance costs account for 27% of the lighting cost), and the use of energy-saving products is the real low cost. In order to achieve energy-saving purposes, many large supermarkets have turned their attention to LED lighting.
Shangchao LED lighting transformation energy saving effect is remarkable
As the fourth generation of green new energy - LED lighting in the government, enterprises and other efforts to promote, LED lighting market gradually opened. Encouraged by national policies and subsidies, LED lighting applications in road lighting and public places have achieved certain results. However, commercial lighting, office lighting, home lighting, etc. are still to be developed. From the perspective of supermarket lighting, some lightings of Wal-Mart, China Resources Vanguard, IKEA, New World Department Store, Suning, Red Star Macalline, Hualian, Huatang, Wanda Plaza, Tianhong, etc. have adopted LED lighting, but they are absolutely large. LED lighting in most shopping malls is still in the replacement stage and does not fully exploit the advantages of LED light sources.
It is understood that the main lamps and light sources used in supermarkets and shopping malls, including compact energy-saving lamps and T5/T8 fluorescent lamp brackets, grille lamps and metal halide lamps, are gradually trying to apply LED lighting products. However, from the perspective of commercial ultra-LED energy-saving renovation, the energy-saving effect is remarkable. For example, in 2008, Honeywell has fully participated in the transformation and implementation of Wal-Mart's energy-saving lighting solutions in China, providing its most advanced and comprehensive LED lighting products including main lighting, refrigerator lighting, fresh lighting and outdoor advertising lighting. And solutions. According to the comparison of electricity costs before and after the transformation of 100 supermarkets, a large Wal-Mart supermarket can save nearly 1 million kWh per year.
Promote the wide application of LED lighting in the four major roadblocks
Promote the general field of LED lighting applications, commercial lighting to play "head gust", and supermarket lighting applications are considered to be the first mature market for LED applications. There are still four major problems in promoting the widespread use of LED lighting: 1. Insufficient luminous flux and limited lighting effects. Since lighting retrofits mostly use standard replacement light source forms, limited power constraints result in insufficient total luminous flux. 2, the color rendering is not good, the lighting quality can not be guaranteed. 3. The reliability is not high and the after-sales service is not perfect. Especially in the current market, LED products are homogenized and the quality of products is uneven. 4. The price is relatively high. Compared with traditional energy-saving lamps, the price of LED lighting products is relatively high, and the price of one-time investment in lighting energy-saving renovation is generally too high.
Summary: In government policies, subsidies and other plans from outdoor lighting to indoor lighting, LED lighting is gradually used in commercial lighting, office lighting, home lighting and other fields. Although LED lighting still has four “roadblocksâ€, it is believed that LED lighting is being applied to a wide range of fields just around the corner with the continuous improvement of LED lighting technology, performance and cost performance.
