According to forecasts, the overall demand for the lighting industry will shrink in 2012. Domestic aggregate demand will shrink by 10-20, and total foreign demand will shrink by 30 or more. Therefore, 2012 is still a difficult year for the lighting industry, especially in the first half of the year. Domestic competition has intensified, and the industry will continue to transition from competition in the field to competition in the bowl. Overall trend: According to forecasts, the overall demand for the lighting industry will shrink in 2012. Domestic aggregate demand will shrink by 10-20, and total foreign demand will shrink by 30 or more. Therefore, 2012 is still a difficult year for the lighting industry, especially in the first half of the year. Domestic competition has intensified, and the industry will continue to transition from competition in the field to competition in the bowl. The upstream and middle of the LED will continue to tighten the belt to live, most of the downstream LED companies are still struggling on the lost line, and some enterprises that find the positioning and breakthrough will live more moist. High-end product development trend: Since high-end products are always built for the consumption class of 20 wealthy 20, it is not affected by the economic environment; and the real high-end products can only be provided by a few brands, so the competition The pressure is not too big. Therefore, high-end products can still maintain a growth of 30-50 next year. The development trend of mid-end products: Due to the impact of the economic situation, the consumption power of ordinary urban citizens and small and medium-sized income groups has generally declined. Therefore, the mid-end products of lighting fixtures have been hit hard in 2011, and they are still bearish in 2012. Therefore, the situation of mid-end products will be relatively slim in 2012. Low-end product development trend: Focus on the third- and fourth-tier markets and rural markets, low-end but better-quality lighting products, the market situation is better, and the space is larger. For a long time, the main market for energy-saving lamps will be concentrated in rural areas. Due to the accelerated urbanization of rural areas and the construction of new rural areas in full swing, the consumption power of this class is very huge. The popular lamps in rural areas will be: energy-saving lamps, ceiling lamps, low-end LED local lighting, traditional crystal lamps and low-pressure crystal lamps. Crystal Light: Due to the improvement of the overall consumption level of the nationality, the development investment trend continues to shift to the central and western regions. The high-end hotels will be built more and more in 2012, and the demand for high-end crystal lamps is strong. Mid-range and low-end crystal lamps will be more popular in urban and rural areas, so the situation of crystal lamps in 2012 will still be better. In particular, low-pressure crystal lamps, along with the maturity of technology, will be loved by a large number of young consumers. Modern lights: The general trend is that modern lighting prices are still bullish, but consumers are more demanding on design and quality. The sleek and simple modern lamps are still the first choice for high-level people with high taste and tight life rhythm, such as the brand of Xinteli and Pinyuan. The elites who like luxury and romantic decoration will choose Baohui, Qilang, Jinda and Austria. The brand of the Sgoona type; the taste of the middle class, the elite, and the senior white-collar workers who like the individuality and artistic atmosphere will choose products such as Micah. These three types of products will become the vane of modern lamp demand. European classical art lights: European lights will become the 2012 unpopular category. Due to the sharp decline in the development of European villas, the number of European lamps will continue to decrease, but the number of groups affected by the European wind is still increasing, so the number of individual passengers cannot be underestimated. The project is still the big head of European lights in 2012, so we must pay attention to working with designers. Inferior European lamps will lose market, and European-style lamps with excellent craftsmanship and good taste will gradually be favored by more people. Chinese-style lamps: The share of Chinese lamps will increase in moderation. Although the wooden lamps are lacking in art and lack of artistic tension, they are quite similar to a class, especially the northern consumers. Therefore, the development force should keep up. At present, Lai Yunda and Bolin are good brands; Warm and not fire, Hailing, shepherd can continue to live more moist in 2012; ceramic lamp crystal Bo Yi, Jingde famous kiln are also good, if not affected by capacity, you can also do more, so there is more room. Overall home lighting: Although the overall home lighting has declined in 2011, the future of the entire category is infinite, and it should be able to increase in batches in 2012. The status quo in 2011 is not only affected by the economic environment, but also because many brands are not clearly positioned, and the products are not working hard. In addition, the channels are floating on the surface, the promotion is weak, the dealers are weak, and so many companies are affected. To Waterloo. In fact, there are many good overall home brands in 2011, such as Op, Euro, Qianpu, Qiantai, etc., because the product or channel positioning is better. Engineering non-standard lamps: With the launch of the domestic demand project, the 2012 engineering lamps will usher in a good momentum of continuous development. In particular, government projects, public works and hotel projects will usher in a golden period of development next year. Electrical Products: Conceptualization and Intelligence are trends in electrical products in 2012. At present, the selling point of electrical products, most manufacturers mainly work hard on functions, structures and materials, and they are already lacking. Therefore, in 2012, the most important thing for manufacturers is to work hard on concepts, work hard on marketing strategies, and work hard on product intelligence control. Energy-saving lamps: Due to the impact of the surge in rare earths, the situation of energy-saving lamps in 2011 has been deepened. The resurgence of halogen powder energy-saving lamps is indeed a major disaster for the industry. In 2012, the halogen powder energy-saving lamp will be crazy for a while, but this momentum will not grow. Although LED products are currently developing rapidly, it is still impossible to eliminate energy-saving lamps in a short time. At least 2012 is impossible. The price is moderate, the quality of energy-saving lamps is still the choice of most people in 2012. China's vast rural areas, energy-saving lamps are even more promising. LED lighting: Although the LED lighting industry seems to have dropped to freezing point this year, it still has a strong growth momentum next year. A large number of government projects and public works will use LED products under the leadership of the government next year. Although there is controversy, this will be an indisputable fact; the civilian sector has also begun to partially enter the market, enter the initial cultivation period, and channel development becomes the life and death gate. LED intelligent control is not only a trend in the future, but also an important selling point for next year.
