Analysis on the development status and competition pattern of LED lighting driver chip industry

] LED lighting driver chip is an integrated circuit that drives LED light by converting power supply into specific voltage and current. Different from traditional incandescent lamps, LED lighting products cannot be directly connected to AC mains due to their sensitive characteristics. In the application process, it is necessary to design a complex constant current drive circuit to stabilize and protect it. As the core component of the driving circuit, the LED lighting driver chip is known as the heart of LED lighting products because its effective power, constant current accuracy, power supply life and electromagnetic compatibility directly determine the performance and life of LED lighting products

led lighting driver chips are mainly matched with all kinds of LED lighting fixtures, which are widely used in home and office lighting, urban lighting engineering, architectural landscape lighting, decorative lighting and other fields. LED lighting driver chips can be divided into general LED lighting driver chips and intelligent LED lighting driver chips. Among them, the general LED lighting driver chip is used to drive daily LED lighting products, and the intelligent LED lighting driver chip adds the functions of full-automatic dimming, color matching, intelligent scene conversion, etc. on the basis of the general LED lighting driver chip, which is used to meet the intelligent needs of LED lighting products under the development trend of smart home and IOT

the competitive formula in the field of LED lighting driver chips: the bureau can be divided into two levels: the first level is the enterprises with high market share, master core design technology and independent research and development ability, mainly including Shanghai Jingfeng Mingyuan Semiconductor Co., Ltd., onbo Electronics (Shanghai) Co., Ltd., Hangzhou Shilan Microelectronics Co., Ltd., Shenzhen Ming Microelectronics Co., Ltd Hangzhou silijie semiconductor concrete pressure testing machine protection technology Co., Ltd. and other enterprises; The second level is mainly a large number of small and medium-sized enterprises, which are small in scale, weak in technological innovation, serious product homogenization and relatively single in model

led lighting driver chips are mainly used to produce LED lighting products. LED lighting products are lighting appliances made by using light-emitting diodes as light sources. They have the remarkable characteristics of high efficiency, energy conservation, environmental protection, easy maintenance and so on. They are an effective way to achieve energy conservation and emission reduction. In the context of global energy shortage, LED lighting will gradually become the mainstream product in the field of lighting, leading to another revolution of lighting sources in the history of lighting after incandescent lamps and fluorescent lamps

in recent years, the price of global LED lighting products has fallen rapidly, and has gradually replaced incandescent lamps, fluorescent lamps and other lighting sources. The penetration rate has continued to increase rapidly. It is expected that the global LED penetration rate will make the internal and external pressure difference of samples reach 36.7% in 2017, an increase of 5.40% compared with 2016

according to the "report on in-depth market research and development prospect prediction of China's LED lighting driver chip industry" released by xinsijie Industrial Research Center, the domestic LED lighting driver chip market scale in 2017 was 2.37 billion yuan. The annual output value of domestic LED lighting applications was about 116.9 billion yuan, 156.6 billion yuan and 204 billion yuan respectively, with a rapid growth rate. The domestic market penetration of LED lighting products (domestic sales volume of LED lighting products/total domestic sales volume of lighting products) reached 42%, an increase of 10% over 2015

led's substitution effect on the lighting market for various temperature control indicators that traditionally fully meet the requirements for low-temperature devices in the national standard gb/t229 (2) 007 metallic Charpy pendulum impact test method has greatly stimulated the demand of the semiconductor lighting market, and the domestic semiconductor lighting industry is expected to usher in key development opportunities. Xinsijie industry researcher predicts that by 2020, the scale of China's LED lighting market is expected to exceed 461.4 billion yuan, and the scale of LED lighting driver chip market is expected to reach 3billion yuan
