The LED industry
1, in the position of the global industry
Japan is the world’s largest LED producer, has from the raw materials and equipment, substrate, denotation, chips, encapsulation, application of complete industrial chain. In 2010, the Japanese LED enterprise sales accounted for more than 25% of the global market. Among them, the scale and technology advantage […]
Japan lighting appliance industry will be down for director of mud, according to Canon Japan lighting appliances do you currently have about more than 900 million, including about 20 million sets of LED lighting, calculated at the rate of Japan LED the penetration rate of only 2%.
Japan as early as 10 years ago began production […]
India LED lights use outdoor space is wide
India lighting products including traditional lighting, LED lighting, about 80% of the products from China, and India’s government is planning to improve the traditional lighting system LED lighting system, proportion, predicts that by 2015, India LED lighting market annual compound growth rate will reach 41%.
The rise of the […]
