The industry economy is in the stage of upward recovery. March was an important turning point. Taiwanese manufacturers' revenue generally turned from negative to positive. Moreover, the revenue data in April continued to improve, and the visibility of orders was extended to one and a half months, that is, the demand heat is expected to continue until middle June. Therefore, some people in the industry judged that the industry's continued upward trend in the second quarter was a high probability event. International manufacturers have promoted the price reduction of LED bulbs, and the demand for lighting is expected to be large. International manufacturers have successively launched low-cost products to stimulate the growth of LED lighting demand. The price drop has increased the advantage of LED lamps over energy-saving lamps, and demand is expected to accelerate. The data also show that Philips and Cree's LED lighting business is accelerating. 13 years is expected to become the first year of LED lighting, and the penetration rate is expected to rise to more than 15. The number of LED lighting is expected to increase by more than 100 in 2013. With the price of LED bulbs replacing 60-watt incandescent lamps falling to US $10 in the third quarter, the compound growth rate of LED lighting output value is expected to reach 3rd in the next five years. Key companies recommend that the chip field should focus on San'an Optoelectronics and Dehao Runda, which have obvious scale advantages and extend to the middle and lower reaches of the industrial chain and have integrated production capabilities. The competition pattern of domestic backlight packaging manufacturers is far better than the lighting field. The main manufacturers Ruifeng optoelectronics and jufei optoelectronics have obvious advantages and will be the big beneficiaries of backlight capacity from Taiwan to China. International manufacturers have been actively promoting LED lighting business for 13 years, and overseas demand has been ignited. Manufacturers who can cut into the overseas OEM supply chain will benefit, recommend sunshine lighting, and recommend paying attention to Zhou Ming technology. In addition, the demand for 12-year street lamp orders was lower than expected due to the change of government. The demand for 13 years will be greatly improved, and it is recommended to use Optoelectronics. Risks suggest excessive expansion of production capacity and a sharp drop in product prices; Demand growth is not as expected.
