The chip technology promotion and prices is the key to promote LED lighting application costs down. With the ascension of the LED chip technology, LED luminous efficiency increase, declining the cost of single star LED chip. Driven at the same time, the upstream investment mass production release, trigger a strong market competition will drive the chip prices fall, the effective drive as a decline in the cost of LED lighting products. In 2011, the chips from the demand quickly converted to supply exceeds demand, the chip prices falling fast. For example, small power 7.5 mil&TImes; 7.5 mil blue chips and high-power 45 mil & TImes; 45 mil 2011 blue chip prices fell 55.9% and 55.0% respectively in a year.
Before 2016, the LED chip makers to expand business, cause excess production capacity significantly, prices continue to decline quickly, upheaval in LED industry. Many poorly run due to backward technology, small firms have cut or transformation, a large number of LED enterprises to withdraw from the market.
At the same time, the strength of state subsidies for MOCVD equipment is reduced, lack of funds of small expansion. Overseas LED chip manufacturer's profits are also showed a sharp decline, product gross margin is low.
However, since 2016, with the steady growth in demand, LED industry supply and demand relations gradually improve, recently it is product intensive rise in price. The personage inside course of study says, is not only the LED chip, screen and so on has risen.
After the manufacturer of demand forecasting is too conservative, resulting in inadequate capacity preparation; At the same time, the intelligent products expand rapidly, the demand for products such as chip screen greatly increased. Superposition of these factors, the contradiction between supply and demand.
Circulating industry carries a three optoelectronic company, according to the official seal of the contact letter depends on January 10, 2017 raised 30 MB/S - S - 32 bb series product prices 8%. Packaging companies star electrical research and development center, deputy director of the confirmed zhi-guo xie, were the star light electric in 2017 the first day of received three Ann photoelectric price notification.
The personage inside course of study thinks, three Ann photoelectric price increases on the one hand, the causes of the cost; Exit, on the other hand, as the small and medium-sized manufacturers, LED chip industry is mainly concentrated in the hands of several large manufacturers, sellers position stronger.
According to the research data shows that, by the end of 2017, LED chip effective capacity of about 83.28 million, demand of about 92.35 million pieces. Among them, 47.04 million pieces of lighting chip demand, a year-on-year growth of 20%; Outdoor full-color displays demand of 26.02 million, up 5%; Indoor small spacing requirements of 1.02 million, up 50%; Mobile phone backlight needs 1.39 million, 440000 tablets backlit demand, computers and TV backlight needs 6.99 million, auto lamps and lanterns requirements of 1.06 million.
