Analysis on development status and competition pattern of LED lighting drive chip industry
LED lighting drive chip is an integrated circuit that drives LED light by converting the power supply into a specific voltage current. Unlike traditional incandescent lamps, LED lighting products cannot be directly connected to ac power supply due to their sensitive characteristics. Therefore, complex constant current drive circuit should be designed to stabilize and protect them in the application process. As the core component of the driving circuit, LED lighting drive chip, its effective power, constant current accuracy, power supply life and electromagnetic compatibility directly determine the performance and life of LED lighting products, and is honored as the "heart" of LED lighting products.
LED lighting drive chip is mainly used in various LED lighting lamps, and then widely used in household and office lighting, urban lighting engineering, architectural lighting, decorative lighting and other fields. LED lighting drive chip products can be divided into general LED lighting drive chip and intelligent LED lighting drive chip. Among them, the universal LED lighting drive chip is used to drive daily LED lighting products. The intelligent LED lighting drive chip adds the functions of automatic dimming, color palette and intelligent scene transformation on the basis of the universal LED lighting drive chip, which is used to meet the intelligent demand of LED lighting products under the development trend of smart home and Internet of things.
LED lighting driver chip in the field of competition can be divided into two levels: first level is higher market share, grasp core technology design, with independent research and development ability of enterprises, including Shanghai crystal FengMingYuan semiconductor co., LTD., the treasure electronics (Shanghai) co., LTD., hangzhou silan microelectronics co., LTD., shenzhen city Ming microelectronics co., LTD., hangzhou silicon semiconductor technology co., LTD and other enterprises; The second level mainly consists of a large number of small and medium-sized enterprises, which are small in scale, weak in technological innovation, serious in product homogeneity and relatively single in model.
LED lighting drive chip is mainly used to produce LED lighting products. LED lighting products are lighting appliances manufactured by using LED as the light source, which are featured by high efficiency, energy saving, environmental protection and easy maintenance, and are an effective way to realize energy saving and emission reduction. Under the background of global energy shortage, LED lighting will gradually become the mainstream product in the field of lighting, leading a revolution in the history of lighting after incandescent lamp and fluorescent lamp.
In recent years, the price of global LED lighting products has fallen rapidly, and it has gradually replaced other lighting sources such as incandescent lamp and fluorescent lamp. The penetration rate continues to rise rapidly. It is estimated that the global LED penetration rate will reach 36.7% in 2017, up 5.40% from 2016.
According to the in-depth market research and development prospect forecast report of China's LED lighting drive chip industry 2018-2023 released by xinsi industry research center, the domestic LED lighting drive chip market scale in 2017 was 2.37 billion yuan. From 2014 to 2016, the output value of domestic LED lighting application was about 116.9 billion yuan, 156.6 billion yuan and 204 billion yuan respectively, with a rapid growth rate. The domestic market penetration rate of LED lighting products (domestic sales volume of LED lighting products/total domestic sales volume of LED lighting products) reached 42%, up 10% from 2015.
The replacement effect of LED on the traditional lighting market has greatly stimulated the demand of semiconductor lighting market, and the domestic semiconductor lighting industry is expected to embrace a key development opportunity. The LED lighting market in China is expected to exceed 461.4 billion yuan by 2020, and the LED lighting drive chip market is expected to reach 3 billion yuan, according to xinsi industry researcher.
