In the third quarter of this year, the lighting terminal market channel re-emerged
According to data from CSAResearch's joint lighting channel survey, in the first half of 2014, the sales growth of LED lighting products in the domestic market entity dealer channel was around 27.8. In the second half of the year, the growth of LED lighting products has slowed down due to the slowdown in national economic growth and the shrinking of real estate. In the first three quarters, the growth rate of the domestic market entity dealer channel was about 25.5, which was still much higher than that of other industries. (According to the National Bureau of Statistics, the average growth rate of China's GDP in Q3 2014 was 7.3). In the first half of 2014, the secondary market broke out obviously. In the third quarter, the third- and fourth-tier markets performed outstandingly and became a bright spot. According to CSAResearch's joint lighting research data, as of August 2014, sales in the third- and fourth-tier markets increased by about 26 compared with the same period of last year, and its growth contributed more than 40 to the overall market growth. In addition, the survey data shows that the brand competition pattern of China's LED lighting products terminal market has taken shape. In the first three quarters of 2014, the market share of the TOP3 brand in physical channel distributors was approximately 22.1, a decrease of 18.4 percentage points from 2013, and the brand concentration of the LED lighting market was significantly reduced. From the perspective of market competition, traditional lighting brands still have certain advantages due to their accumulated resources for many years. Among the top 20 brands in the sales ranking, traditional brands such as Op, NVC, Foshan Lighting, Philips, Sanxiong Aurora and other brands still occupy 15 seats. The other 5 seats were seized by emerging brands such as Mulinsen, Yiguang, Qinshang, Changfang and Teyoushi. From the perspective of growth rate, the growth rate of emerging brands is much higher than that of traditional lighting brands. Mulinsen and Yiguang are the two brands with the fastest expansion. At the same time, from the perspective of single products, emerging brands began to attack traditional strong brands, and some brands have obvious competitiveness. CSAResearch believes that 2014 is a year of rapid explosion in the LED lighting market and a year of influx of brands. With the advancement of urbanization, consumers' pursuit of quality of life is getting higher and higher, and the LED lighting terminal market channel will continue to rise. At the same time, the traditional lighting brand and the emerging LED brand confrontation incentives, but the quality and cheap Chinese good products still lead the market, especially in some market segments, the brand competition pattern has begun to take shape.
