Foshan LED is facing the embarrassment of technical problems

    It is not too much to say that foshan LED lighting industry is in full bloom, but there is no denying that foshan LED lighting is hot in the industry and cold in the market.Why the embarrassment?This is because the current technology for high-power LED lighting has no obvious energy-saving advantages compared with the existing high-efficiency light source, and the initial investment cost is much higher.Large current is also converted into heat energy while improving light efficiency. If the heat dissipation is not well handled, the LED life will be greatly reduced, and the use of radiator will increase the cost and volume, so that the advantage of LED light source disappears.So it's all LED technology that's not up to the lighting market.

    Currently, LED packaging cost accounts for 50%. In order to reduce the overall cost of LED, we must choose a more appropriate packaging structure. Therefore, changing the existing packaging structure to achieve reasonable packaging cost will be the most effective and direct way for LED lighting to be accepted by the market.Of course, LED chips continue to reduce costs as the process, shipments increase, and larger wafer fabrication processes are adopted. In recent years, the annual rate of decline is 20%. If the current packaging cost can be reduced from 50% of the total cost to 20% ~ 30%, the application of LED lighting will be a new order of magnitude of the market size.

    It is up to the whole industry chain to bring down costs and mature technologies.The upper, middle and lower reaches of the LED industry chain are epitaxial materials and chip processing, product components and module packaging, display and lighting applications respectively.

  LED epitaxial wafers and chips account for about 70% of the industry's profits, LED packaging accounts for about 10% ~ 20%, LED application accounts for about 10% ~ 20%.Statistics  show that there are more than 3,000 semiconductor lighting manufacturers in China, 70% of which are concentrated in the downstream of the industry. Domestic LED epitaxial materials and chips are mainly medium and low grade, and more than 80% of power LED chips and devices depend on imports.

   In recent years, the government has built a number of LED lighting industry bases with pepper, but China's LED industry boom is still at the expense of 70% of the Chinese people competing for the 10% ~ 20% profit share of LED.This means that if foreign companies in charge of the core LED technology do not rush to lower the cost of LED, foshan LED industry downstream of the cluster can only sacrifice their own profits to achieve low prices and make the market hot, but without technical support of downstream products, even if the price is lower, how many people dare to use it.
