Introduction to the LED lighting lamps and lanterns of patent layout planning

LED lighting lamps and lanterns technology problem at present is as follows: 
1, the domestic enterprise without core technology 
LED industry in the upstream of the vast majority of the core patents in foreign company‘s hand, we don‘t have to master the core technology, domestic although we LED application products manufacturing capacity accounted for 50% in the whole world, share to 50%, but in profit link is the lowest. Mainly in the cost of the LED chip LED lighting lamps and lanterns, as long as the chip prices down, LED the lumen of the unit price to with the present stage of energy-saving lamps. Because the increase in the number of LED chips with technology, a larger wafer production process, will continue to reduce costs, reduced every year 20% speed in recent years, the LED chip price factor, will lower photosynthetic efficiency of ascension are also included in the price, the same price to buy the better product, so the LED chip is a price cut space. 
2, LED application products 
Cooling costs remain at 5%, the actual thermal design is very simple, held the two directions: one is that the LED chip and heat dissipation device path as short as possible, the shorter your thermal design is better; Second, heat resistance, is must have enough heat to the path at the same time, also want to have enough "cooling way", the cost in the main structure, the structure design about 20% in the lamps and lanterns, used for heat dissipation cost is not much. Now the biggest problem is how to be more creative, more reasonable structure design. 
3, LED application power supply 
Power is the most weak link in LED lighting lamps and lanterns, restricting the development of LED lighting lamps and lanterns. Now about 20% of the cost of LED lighting lamps and lanterns design, some high, with the development of technology power in 5-10% probably the most reasonable. LED light source compared with other light source the afterlife, in fact, now the cost is not high, especially the LED environmental protection, energy saving, do not contain mercury, and each quarter the price of LED lighting lamps and lanterns are slipping, in a relatively short period of time the price of the LED lighting lamps and lanterns can achieve acceptable levels.
