LED-illuminated LEDs are made of III-IV compounds, such as gallium arsenide, gallium phosphide, gallium arsenide, etc., which utilize solid semiconductor chips as luminescent materials. Rare metal gallium is widely used in the modern semiconductor industry, mainly in the presence of compound gallium arsenide, accounting for about 80% of the total application of metal gallium. Gallium arsenide is mainly used in 3G mobile phones, semiconductor wireless communication and LED lighting. According to foreign media reports, Taiwan's supply chain companies expect that the global LED lighting market output will increase by 30 in 2015, and the doubling of shipments will offset the negative impact of the price drop of 30-35. According to research institute LEDinside, the total output of global LED lighting will reach 25.7 billion US dollars in 2015, accounting for 31.3% of the total output of the overall lighting market. The industry expects that European production capacity will account for 23% of the global LED lighting market next year. 21, the United States accounted for 19. Industry sources said that compared to the overall growth of the LED lighting market, the LED backlight market will decline, mainly because the new LED TV requires less chips than the backlight LCD TV, while the price of the backlight LED chip It is also falling. An important trend in the LED industry recently is the continued growth in demand for indoor LED lighting equipment and the decline in LED chip/component business. According to the financial report released by CREE, the leading LED lighting company in the United States, the sales of LED lighting products of the company increased by 51 to 223 million US dollars in the third quarter of this year, while the sales of chip/component business decreased by 20 to 173.6 million. According to US semiconductor supplier Rubicon Technology (RBCN), the weak LED backlight market will have a significant impact on the company's current quarterly results, and it is expected that demand will not pick up until the first quarter of next year.
